Gram +/- BACTERIA
GRAM (+) BACTERIA
Branching Filaments
- ONLY anaerobic / facultative
Branching Filaments Gram +
- Anarobic = Actinomyces
- Aerobic = Nocardia
- Treatment for BRANCHES = SNAP them
--> SN = SMX-TMP Sulfonamides --> Nocardia
--> AP = Actinomyces --> Penecillin
-
Anaerobic
- "ANaerobic = ActiNomyces"
*ActiNomyces
- "ANaerobic = ActiNomyces"
- ACTINO --> not acid fast
- Actinomyces = Aspirated food infection
--> mistaken for lung abcesses, TB and lung cancer, etc.
ACTIN O MYCES PORN SCENE with the DENTIST and ANAROBE ANT IN A ROBE
- the low lighting from the HANGING HYPHAE BRANCHES all
--> branching Hyphae
- SET in the LOVE MOUTH BED FULL OF FLOWERS
--> ACT IN O MYCES PORN SCENE is normal mouth flora
- the DENTIST pornstar is doing DENTAL work before the scene
--> you usually catch ACTIN O MYCES PORN SCENE from DENTAL WORK
- the direct = PENICILLIN PENCIL gives the hot ANAROBE AUNT an IUD so she wonlt get pregnant
--> ACT IN O MYCES can cause infections in IUDS
when the ACT IN O MYCES PORN SCENE is over shit hits the fan because IN A ROBE AUNT gets an infection that SPREADS to her URINARY SYSTEM--> common in ACT IN O MYCES infections
- YELLOW PUS OOZES everywhere
- the PENCIL DIRECT ENDS the scene ao he can jump in for the next one
--> tx with high dose penicilin
-
Aerobic
- "Aerobic Fillaments = ARABs fill NO CARDS"
*Nocardia
- "Aerobic Fillaments = ARABs have NO CARDS to get in"
- slightly acid-fast = Ziel Neilson stain
--> like mycobacteria tuberculosum
- note that Nocardia can almost never infect normal people since NO CARDS to play... = no virulence factors to get past the immune system
--> ONLY infect immunocompromised people
- when it does, it is almost always RTI pneumonia
--> 50% go on to brain abscess and seizures
Acid Fast Staining / Ziel Neilson Stain
- only Nocardia and mycobacteria tuberculosis are acid-fast
- first stain with analine dye = carbolfuscin = red dye
--> binds with mycolic acid
- then alcohol to wash away non-acid fast cell walls
- counterstain blue
-
-
NOCARDIA ADVENTURE on PAPER that leads to the
- you start to DREAM ABOUT AEROBICS with a STAPH CAT who starts UREASING your notes to distract you
--> NOCARDIA is STAPH CAT +
--> NOCARDIA is AEROBICS
--> NOCARDIA is urease +
- you then get distracted by a ACID FAST LEMON
--> stains + on acid fast stain
the ACID FAST LEMON leads you to the foot of a massive BRANCHING TREE
- you start to look around the NOCARDIA BRANCHING TREE until you see a CLUMP OF DIRT that seems to be hiding something
--> NOCARDIA BRANCHING TREE is found in the soil
- you start to dig up the soil until you find a hidden FIRST AIDs KIT with a + cross sign on it with LOTS OF BAND AIDS
--> NOCARDIA BRANCHING TREE is a gram + branching filament
--> it affects people with AIDS mostly
you then look up to see some HANGING BEADS
- NOCARDIANG BRANCHING TREE looks like beaded filament on microcsope
- these beads lead you down a CAVITATING LUNG where you climb down the BEADED ROPE
- this was a mistake as it leads you into the layer of BRAIN and LIVER ABSCESS GUY
--> NOCARDIA BRANCHING TREE causes liver and brain abscesses in AIDS people
-
Treatment for Gram + BRANCHES = SNAP them
- SN = SMX-TMP Sulfonamides --> Nocardia
- AP = Actinomyces --> Penecillin

Nocardia = ARAB who has NO CARDS to play...
- "ARAB" = aerobic
- "NO CARDS" = no virulence factors to get past the immune system
Bacilli
Bacilli / Rods
Anaerobic
*Clostridium Family
- "C DIFF = C cup TITZ and BOOBZ are DIFFICULT to PERFECT"
--> TITZ = clostridium tetani
--> BOOBZ = clostridium botulinum
--> DIFFICULT = Clostridium dificile (C. dif.)
--> PERFECT = clostridium perfringens
Clostridium Difficile
- "It's DIFFICULT to attach 2 White CAP BOOBY TASSLES"
- C. difficile is mostly found in soil but
--> but also found in a very small portion of the body as normal flora
- CAP = CYTOskeleton B toxin , A toxin cAMP, pseudomembranes
- note that both normal flora of mouth and anus (Candida and C Diff) have pseudomembrane formation
-
CLOSTRIDIUM CLASSROOM of DIFFERENTIAL equations
- all CLASSROOMS = clostridums have POSITIVE students and are equipped with TEACHING pointer RODS
--> clostridium family are GRAM POSITIVE RODS
- bad kids in the classroom DAYDREAM of BOOBY tassles with 2 WHITE CAPS on them
- CAP 1 = toxins of C DIFF
--> C = cytotoxic b toxin --> cytoskeleton
--> A = A toxin --> increases cAMP and gives dirrhea
--> P = pseudomembrane (white) colon
- CAP 2 = drugs cause C DIFF
--> C = clindamycin = chalkboard CLEANING MICE and VAN of MICE
--> A = ampicillin = PENCIL AMPS
--> P = PPIs
- one student = SUMO fat kid gets in trouble for playing with his PSUDOMEMBRANOUS COLITIS in the middle of class
--> pseudomembranes in both major microbiota of mouth and colon (candida albicans + c diff)
- as punishment the SUMO FAT kid has to show everyone his MEGACOLON
--> C diff gives megacolon
- to get rid of C DIFF / escape from the though of being in the classroom
- Kids DAYDREAM again, but this time of how to get TRANSPORTED out of the C DIFF classroom
--> FIRST by a METRO KNIGHT train drove by a KNIGHT = Metronidazole
--> after the METRO KNIGHT train doesn't work they need to hire some more dangerous and out of control THUGS
--> last resort = dream of VAN full of CLEANING MICE = Vacomycin comes to bust them out

Clostridium *Perfringens
- C DIFF - PERFECT BOOBZ
- cause perforation of the colon
Virulence Factors for Clostridium perfringens
- 2 main toxins for perfringens
--> one causes the gas gangrene of necrosis
--> one causes the "perforating" of cell membrane seen in perfringens
lecithinase = phospholipse C
- this is a "dirty version" of our human phospholipase A2 that is used in arachanodonic acid waterfall for cleaving arachanodonic acid from the cell mebrane to make eucosanoids
rapid glucose metabolism of C perf.
- this is what causes the characteristic gas gangrene of necrosis in c. perf.
- 1 more item...
CLASSROOM for PERFUMES with the very hot and sexy (alpha lecithinase) AFRO-LACED THIN teacher
- all the SPORE boys in the class DROOL over her and her AFRO
--> AFRO perfringens creates spores
--> she sprays them all with perfume and tries to dance for them
- BUT her AFRO always gets stuck in the plasma membrane garland above her head
--> lecithinase PERFORATES plasma membranes
- on the wall there is a MUSCLE MAN where the classroom pet MUSCLE NECROSIS CROW sits
--> the little boy SPORES love to piss off the bird and spray it with gangrene GREEN perfume
- 1 more item...
*SNARE cleaving clostridium toxins
- clostridium botulinism vs clostridium tetani
- both cleave SNARE proteins
- key difference is tetani travel retrograde (same as Rabies virus) to GABA neurons and prevent GABA inhibition
- botulinism stay in the ACh NMJ where they entered, cleave the SANREs and stop ACh release
--> sustained relaxation of muscles
- tetani after retrograde to GABA neurons, cleave the SANREs and stop GABA release
--> sustained contractions of muscles
--> orthopismus
Clostridium *tetani
- blocks inhibitory neurons
--> blocks GABA and Glycine
- trismus = lock jaw
- found in mammal GI tracts normally
- get deposited in the soil everywhere
- release tetani toxin
--> travels retrograde through axons to block anterior horn inhibition
- tetanus of muscles
- "BATS with SNARE NAILS = Joker's MUSCLE thugs"
--> "BATs with SNARE nails" = tetanus cleaves SNARE
- 2 more items...
Clostridium *Botulinum

- 1 more item...
Tetanus vs Rabies vs Botulism
- Tetanus = muslce SPASMS and LOCK JAW
--> puncture wound Hx / Injection Drugs
- Botulism = BODulDYSM double vision and 4 DYSs SPASMS and LOCK JAW
--> dysphagia, dysarthria, dyspnea
- Rabies = hydrophobia, fever, hyperactivity
--> think animal in HEAT and hyperactive, salivating and hydrophobic
--> Hx of animal bite
-
"C DIFF = C cup TITZ and BOOBZ are DIFFICULT to PERFECT"C DIFF:
"ClostridiuNN = It's DIFFICULT to attach 2 White CAP BOOBY TASSLES"
- "ClostridiuNN 2 WHITE caps" = neutrophils make up the white caps
--> Toxin A recruits neutrophils for inflammation
"CAP 1" = neutrophils make up the white caps
- "C" = Cytotoxic B toxin = causes bowel wall necrosis and pseudomembranes
- "A" = A toxin - causes neutrophils to come and cause inflammation
- "P" = pseudomembranes
--> these cover the mucosa, can't absorb
--> cause watery diarrhea
"CAP 2" = ABx and PPIs that cause C diff
- "C" = clindamycin
- "A" = ampicillin
- "P" = PPIs
C Tetani:
"BATS with SNARE NAILS = Joker's MUSCLE thugs"

--> dysarthria
--> dysphagia
--> dyspnea
- "BOTULISM = BOTTLED honey"
--> botulism toxins found in can goods
--> especially honey with children
*Spore formers and boiling temperature survival
- both clostridium family and bacillus anthracis can survive boiling temps
--> reason why you ned autoclaves in hospitals
-
Aerobic
*Listeria Bacillus
- C. Diff. = butt vs Lysterine = other holes (mouth + vagina)
--> Listeria AEROBIC vs C Diff anaerobic
- Listeria usually only causes infection in birth infants and HIV/immunocompromised
- "Listeria BACILLUS = Lysteria BABIES (mouth + vagina)"
--> "BABIES mouth" = Lysteria in unpasteurized milk
--> "BABIES vagina" = Lysteria + GBS in vagina of mother
--> mother - child transmission at birth
- in pregnant women
--> passed on through placenta, birth or spontaneous abortion
--> need to be screened at 36 weeks
--> cause birth canal --> infant transmission
- "tumbling G+ rods" + red rocket tails
--> think "LISTEN for the tumbling LISTERIA in the bottle when you drink KEVS milk"
--> tumbling G+ rods
--> unpasteurized milk
-

--> LISTERIA LIZARD is both STAPH CAT POSITIVE and BETA HEMOLYTIC
-
LISTERIA LIZARD serves SOFT CHEESE to the PREGENANT MOM and her entire FAMILY
- LISTERIA LIZARD serves soft cheese
--> Listeria lives in the fridge and will often go in soft cheese like Brie or feta
- Pregnant women can get Listeria and pass it on to their infant at birth or during pregnancy
--> during pregnancy infection = can casue spontaneous abortion
--> pregnant mothers are screened for Listeria 2 weeks prior to due date to rule out infection
-
Cytotoxic T cells destruction of Listeria = Key defense
- note that listeria is INTRACELLULAR
--> think of the Listeria lizard = INSIDE the refrigerated cell of the desert
--> thus listeria like all other intracellular pathogens need cytotoxic T cells to kill the cell and lyse it
--> exposes the intracellular listeria to activated macrophages
- note this is also key that the Cytotoxic t cells also activate macrophages since some intracellular bugs can evade the lysosome destruction if the macrophage isn't activated
-
*Viurlence for Listeria
- able to live in cold temperatures
--> reason why Listeria can contaminate unpasteurized milk and processed meat in the fridge
*Bacillus Anthracis
- "Bacillus Anthracis = BACKS Anthracis" =
--> backs of animal hydes coomon to get anthrax
- bacillus anthracis toxin
- "Bacillus AN thra CIS = Bordatella Tuss CYS" = adenylate cyclase CIS
--> mimics the adenylate cyclase to increase cAMP
--> inactivates macrophages and evades the immune system
- "Bacillus AN thra CIS = Bordatella Tuss CYS" = also has edema factor the same as bordatella pertussis

- SKIN SUIT MAN has NECROTIC BLACK 3rd degree burns on his back and is holding up a sign with a NECROTIC CROW on top of it saying IM OKAY IM NOT HURT I SWEAR
--> ANTHRAX TRACKS gives necrotic BLACK ulcers on the skin
--> these necrotic ulcers looks bad but they are PAINLESS
- ANTHRAX TRACK explosion at the SHEEP WOOL FARM
--> anthrax in sheeps wool and other hides
--> the explosion killed a bunch of sheep
--> GI GUY didn't want the sheep to go to waste so he ate one and DIED

"Landan Learns the CD --> ABCDE's of CORN DIPPING FAIR"
- Landan = Grey/white Calking in the back of the mouth
--> pharingitis membrane is key in P/C
- A = ADP of EF = elongation factor 2
--> EF2 needed for elongating the polypeptide chain of ribosomes for protein synthesis
--> this is how the diptheria toxin kills cells
- B = Beta prophage is what spreads the toxin

*Hib = Haemophilis Influenzae B
- common cause of infection in children
--> epiglottitis, ear infections, meningitis
- HIB for toddlers = "Hemophilis throat, Influenza ears, B brain"
- Hib main virulence factor is PRP polysacharide capsule
--> what the Hib compliment vaccine makes antibodies for
- PRP polysacharide capsule evade phagocytosis and also stops the C3b compliment system

--> allows it to infect the brain
--> other non-typable HIb are normal RT flora and don't have a polysaccharide capsule
Clinical Cases
Hib = Haemophilis Influenzae B example
- Hib is most common cause of epiglottitis
-
-
Notes:
- children with epiglottitis present with fever, dysphagia, dyspnea
- adults have milder symptoms and present with sore throat
- many cases of epiglottitis from Hib are prevented by the Hib vaccine, but some still occur
-
-
*Virulence Factors for Hib
- PRP polysacharride
--> part of HNS bacteria
-
*EMOP infections from Hib
- note that Hib vs Non-typable H. Infl. are very different
- Hib is the PRP strain that can cause the EMOP infections
--> O is OMITTED though
--> Ottitis media is from NON TYPABLE Hi infections
--> reason why kids will always have a high rate of H. Influenza ottitis media (no vaccine for it)
Hib (Influenza Ears) Ottitis media
- Ear Hib are nontypable
--> non-typable HIb are normal RT flora and don't have a polysaccharide capsule to infect brain
--> nontypable are NOT covered by the Hib vaccine
- B brain = meningitis in toddlers
--> type B HIB is the strain that has polysacharride capsule
--> allows it to infect the brain
-
Hib (Hemophillis throat) Epiglottitis
- thumb print sign on imaging
- kids who have not gotten the Hib vaccine
-
-
*Tybable B vs Non-typable infections from Hib
- note that Hib vs Non-typable H. Infl. are very different
- Hib is the PRP strain that can cause the EMOP infections
--> O is OMITTED though
--> Ottitis media is from NON TYPABLE Hi infections
--> reason why kids will always have a high rate of H. Influenza ottitis media (no vaccine for it)
-
HEME UP IN a FLUTE HEMOPHYLUS takes NUDE MONA out on a DATE
NUDE MONA she CHOKES on a RED CHERRY EPIGLOTTITIS and is saved by a COPD COP
- HEMOP causes epiglottis
- HEMOP causes COPD exacerbation pneumonias
meanwhile a group of MEN IN TIGHTS under 18 are routy at the table next to them
- HEMOP causes MEN IN TIGHTS for young adults age < 18
CHEF TRIAXONE cooks at this restaurant and REFERREE with AXES is the floor manager who gives a THUMBS UP to the COPD COP for removing the RED CHERRY EPIGLOTITITS from NUD MONA
- CHEF TRIAXONE is the treatemnt for HEMOP IN A FLUTE
- REFERRE with PRUPRLE AXES is the prophylaxis for people exposed
- THUMBS UP from teh manager
-
"Nice Small Ds milf /pregnant from BRUCE's COCK..."
- Small D COCK = coccobacillus
- pregnant milf = think of vaccines for kids
--> Hib + pertussis
- BRUCEs COCK = coccobacillus --> think of Brucellosis for kids
"gets NO Hib vaccines for her kid ELLA and feeds her unPASTEURIZED milk..."
- ELLA and unPASTEURIZED milk = Brucella and Pasteurella
"gets Double DD's implants and works at MALL and MOXY's"
--> these are the Double DD Diplococci at MALL and MOXYs
*Bordetella Pertussis
- causes pertussis = whooping cough
- starts with general malaise as normal infection
- tussis = emesis after large coughing spells
- MUST be considered in ANY adult who has similar symptoms and no booster vaccines
-
BORDETELLA PERTUSIS TEXUS BORDER
- can't keep ADP REBULLS out they smash through the thin wall and hit the GI JOE border guards
--> their cAMP guns fire into the air as they get tackled
ILLEGAL immigrant babies on BOTH SIDES of the border
- 2 phases of BORDATELLA PERTUSSIS BORDER
- 1st phase = CAT PHASE
--> this is on the TEXAS side of the BORDETELLA PERTUSSIS BORDER
--> where the ILLEGAL IMMIGGRANT babies are being held in deplorable conditions with a CAT infestation
--> the CATS in the BORDETELLA PERTUSSIS BORDER camp jumps from baby to baby and spreads the infection before they have any sypmtoms
- 2nd phase = PAROXYSOMAL CHOKING on a PEAR phase
--> this is on th mexico side of the border where they send the kids and don't care any more
--> this is the WHOOPING COUGH paroxysmal attacks
LYMPHOCYTIS LIMES stuck in the PERTUSSIS BORDER RIVER
- BORDETELLA PERTUSIS BORDER catches LYMPHOCYTE in the bloods stream and stops them from migrating out from the blood
- this causes DROVEs of INSULIN INSECTS to come to the BORDER to feed on the SWEET LYMPHOCYTE LIMES
--> BORDETELLA PERTUSSIS BORDER causes hypoglycemia
-
-
*Yersinia Bubonic Plague
- south west US areas
- zoonotic
--> resevoir in rodents
--> gets into humans by rodent flea bites
- key presentation is inguinal lymphadenopathy = LAD
- paper clip looking on stains
-
Gram (-) *Comma Shape Rods
- note ALL comma shaped rods are
--> OXIDASE postive
--> think you need to take your oxygen tank to each continent
- "3 comma - shaped continents..."
- "CAMP in a BUBBLE in July at 42 degrees in Africa"
--> Campylobacter
- "sleep on A ROCK in VIBRANT COLORADO"
--> Vibrio cholera
- "UR EASY to take a HELICOPTER to Australia"
--> Helicobacter Pylori
- "**3 comma - shaped continents..."
- "CAMP in July at 42 degrees in Africa"
--> temp = 42
--> CAMP in JULY = Campylobacter jejuni
- "sleep on A ROCK in VIBRANT COLORADO"
--> A ROCK = alkaline
--> VIBRANT COLORADO = vibrio cholerae
- "UR EASY to take a HELICOPTER to Australia"
--> UR EASY = urease producing to avoid duodenum destruction
--> HELICOPTER Australia = Helicobacter pylori stomach ulcers in Australia
*Campylobacter jejunum
- Campylobacter jejuni is the LEADING CAUSE of BACTERIAL ENTEROGASTRITIS
--> bacterial gastroent. is campylobacter until proven otherwise
- live in 42 degrees
- "CAMP in a BUBBLE in July at 42 degrees in Africa"
--> temp = 42
--> CAMP in JULY = Campylobacter jejuni
--> CAMP in a BUBLE = Campylobacter - causes colonic abscesses
Campylobacter Guillan Bare Syndrome
- autoimmune that destroys Schwann cells from most dital to proximal
- comes after campylobacter infections (also viruses)
-
CAMP CAMPYLOACTER 42 DEGREES
- the WRITER KING ARTHUR who sits on his THRONE writes home to his mother about how terrible CAMP CAMPYLOACTER 42 DEGREES is
--> Rieters Syndrome comes after a CAMP CAMPYLOACTER infection
- the flag at CAMP CAMPYLOACTER 42 DEGREES is made of a
--> CORKSCREW shape
--> the flag is a flagella at CAMP CAMPYLOACTER 42 DEGREES
- GREEN BERET camp Counciller
--> GB syndrome happens after a CAMP CAMPYLOACTER infection
- the CHCKEN is served RAW at CAMP CAMPYLOACTER 42 DEGREES
--> 42 degrees is not hot enough to cook the chicken
- the weirdest thing that the WRITER KING ARTHUR has seen at CAMP CAMPYLOBACTER 42 degrees is a dog sucking MILK right from the TIT of a COW and then SHITTING with DIARRHEA everywhere at the camp
--> campylobacter can be in raw milk
--> campylobacter can be in dogs diarrhea
WRITERS SYNDROME WRITING KING ARTHUR at CAMP CAMPYLOBACTER 42 DEGREES
- writing in the toilet to his mother how much CAMP CAMPYLOBACTER SUCKS
-
GREEN BERET camp Counciller at CAMP CAMPYLOACTER 42 DEGREES
- note that GREEN BERET syndrome has muscle paralysis that ascends from the FEET UP
-
*vibrio cholera
- Alkaline positive
- "sleep on A ROCK in the SUNSHINE STATE = VIBRANT COLORADO"
--> A ROCK = alkaline
--> VIBRANT COLORADO = vibrio cholerae
--> Colorado River is Sparkling CLEAN = High volume watery diarrhea
/ no inflammation or Leukocytes
- in COLORADO, clean water and eat ONLY rice water
"sleep on A ROCK in the SUNSHINE STATE = VIBRANT COLORADO"
- A ROCK = alkaline
- VIBRANT COLORADO = vibrio cholerae
"If you CAMP for a LONG long time in Colorado, bring an Oxygen Tank, and some RICE WATER"
- CAMP for a LONG long time
--> Cholera entertoxins cause permanent Gs cAMP activation
--> causes
VIBRANT COLORADO RICE WATER COLLY FIELDS controlled by the MEAN ADP REDBULL with APPLE on and B on his SHOULDER
- with the border COLLY on the POT IRRIGATION SYSTEM
- controlled by ADP REDBULL with APPLE and BEE
--> ADP Ribosylating AB toxin
--> turns up Gs --> cAMP levels
--> diarrhea
- pushing the G SPOT button to INCREASE the cAMP
- this is the RICE WATER COLLY FIELDS in the low elevation of COLORADO, not the COLORADO ROCKIES
--> lots of O2 to break down compared to the high elevation hyperventilation
--> Oxidase POSITIVE
RICE WATER COLORADO COLLY keeps dropping his IRRIGATED COMMA SHAPED SHRIMP from his private ALKALINE COLORADO lake
- after a hard days work IRRIGATING THE RICE WATER fields of VIBRANT COLORADO
- VIBRANT COLORADO COLLY comes home to relax in his VIBRATING CHAIR
- where he is SERVED by the NUN-MILK lady --> milk and his favourite COMMA SHAPED SHRIMP to eat from
- the COMMA SHAPED SHRIMP are from his own PRIVATE ALKALINE LAKE
- the COMMA SHAPED SHRIMP are what give him enough SALT to shut off the CL- channels and Na+ channels of the IRRIGATION GUT of RICE WATER FILEDS in COLORADO
--> increase cAMP and give RICE WATER DIARRHEA
-
ADP REDBULL with APPLE and BEE
- ADP Ribosylating AB toxin
- pushing the G SPOT button to INCREASE the cAMP
--> turns up Gs --> cAMP levels
--> diarrhea
- note that the GDP REDBULL with APPLE and BEE on his SHOULDER
--> ALWAYS increases cAMP
--> either through increases Gs stimulation
--> or Gi inhibition
--> both will increase cAMP levels and cause diarrhea usually
-
-
*Stool findings in Vibrio Cholera
- NO leukocytes or blood
- ONLY mucus from goblet cells
--> "rice water diarrhea"
-
Vibrio cholera is very sensitive to stomach acids
- needs a very hihg amount of cholera to cause infection due to this
- thus cholera can more easily affect people on PPIs, etc.
-
*Helicobacter Pylori = H. Pylori
- Urease positive
- "UR EASY to take a HELICOPTER to Australia"
--> UR EASY = urease producing to avoid duodenum destruction
--> HELICOPTER Australia = Helicobacter pylori stomach ulcers in Australia
*PUD and H. Pylori
- quadruple = TETRA METRO therapy
- 2 Abx
--> "TETRO METRO"
--> tetracyclines + metronidazole
- PPI == omeprazole
- bismuth chelate
-
HELICOPTER TERRORIST
- blowing holes in the DUODENUM
- HELICOPTER TERRORIST is with his terrorist FRIENDS the ADENOMA and GNOME in a CAR who are drinking MALT LIQUOR
--> HELICOPTER TERRORIST causes adenocarcinomas
--> HELICOPTER TERRORIST causes MALT LYMPHOMAS
- HELICOPTER TERRORISThas lots of AMMO
--> can make AMMO ammonia with urease
- there are 2 hostages in the DUODENUM of the HELICOPTER TERRORIST
--> STAPH CAT = cat +
--> OX DAISY = oxidase positive
- it takes 2 ABX soldiers with a PPI gun to take down the HELICOPTER TERRORIST
-
Dx of H pylori
- urea breath test or facal antigen test
- note if a patient starts taking any one of the 3 ACP treatments before the test then it will give a false negative test
--> this is because the bacteria have been snuffed out a little bit but are not completely gone
--> especially for a PPI
-
-
-
-
Acute = Non-atrophic vs chronic ATROPHI H. Pylory infections
- acute H Pylori
--> start int he antrum
--> infect G cells and increase gastrin and stomach acid
--> risk of duodenal ulcers
- chronic H pylor
--> moves up the body and to the fundus
--> more danger for gastric ulcers
--> actually get LOWER acid production since they have now killed off alot of the G cells
--> it is now the inflammation that is causing the ulcers
--> MALT lymphomas
*Acute Non-atrophic
- NON - atrophic
--> means that the damage or ulcers are from the excess gastric acid production
--> and NOT from atrophy of the cells and necrosis from H pylory going into the bdy and the fundus
-
*Chronic Atrophic
- chronic = YES - atrophic
--> means that the damage or ulcers are NOT from the excess gastric acid production
--> BUT are from atrophy of the cells and necrosis from H pylory going into the body and the fundus
- chronic atrophic --> leads to MALT lymphomas
-
-
*Properties of Bacteria
-
*Oxidase Positive organisms
- most are gram -
- NOTE the 3 Comma Continent are positive
- the EEK Lactose fermenters are NEGATIVE
-
*Catalase postive organisms
- Staph CATS like their own SPACE
-
*Toxins from Bacteria
- either endotoxins or exotoxins
*Exotoxins
- ALL are unique
- most activate Adenylate Cyclase and cAMP pathway
--> either directly or through inhibiting Gi inhibition
Toxic Shock Syndrome Toxins
- TSS TSS, say the FRS (Friars)
--> TSS = FRS = fever, rash shock
- major Staph CAT and Rheumital PYTHON
--> Staph A and StreptO PYO
- StreptO PYO
--> 2 antigens for Rheumitral Python
--> Peforating cell membrane = O antigen for cell lyse like clostridium Perfringens
--> toxic shock syndrome = TSS / FRS = A antigen like STAPH CAT
- bind the MHC 2 and TCR outside normal area
--> cause massive cytokine release
LYSE cell membrane toxins
- perfringens and StreptO PYO
--> 2 antigens for Rheumitral Python
--> Peforating cell membrane = O antigen for cell lyse like clostridium Perfringens
Watery Diarrhea = increase Fluid secretion
- increasing either cAMP or cGMP pathways
*cGMP toxins "cAMPing outside your BORDERS gives you TRAVELLER's diarrhea"
- "Travellors feel LABILE/LIGHT in the AIR, and STABLE on the GROUND"
- travellors ETEC BOTH cAMP and cGMP
*cAMP toxins"Bacillus Anthraxis = BACKS of Animals ANTHRA - CYS"
- "BACKS of Animals" = Anthracis from animal hides
- "Bacillis ANTHRA - CYS" = Adenylate Cyclase cys actions
--> same as bordatella pertus CYS
"cAMPing outside your BORDERS gives you TRAVELLER's diarrhea"
- "cAMPing" - increased cAMP = watery diarrhea
--> less absorption of salt and water
--> watery diarrhea
- "outside BORDERS" = Bordatella pertussis increases cAMP
- "TRAVELLERs diarrhea" = ECTC increases cAMP
- also increase cGMP like Yersinia
- "Travellors feel LABILE/LIGHT in the AIR, and STABLE on the GROUND"
Elongation Factor = EF = Protein synthesis toxins"DIP your ELONGATED PSEUDO BULL neck into the apple bob"
- Diptheria and pseudomonas inactivate Elongation factor and cause cell death
- Diptheria present with a BULL NECK lymphadenopathy and pharyngitis
*Endotoxins
- ENDOTOXIN gives the 3 components and 3 activation pathways for endotoxins
- LPS APO
--> A = A antigen ANCHOR = toxic part that ANCHORSthe LPS to the membrane
--> P = olysaccharid
--> O = O antigen
-
-
*Capsulated Bacteria
- "some nasty killers have serious capsule protection"
- note that capsulated bacteria are more likely to infect Sickle cell patients who have asplectomy or improperly functioning sleepns
-
*Intracellular organisms
Cytotoxic T cells destruction of intracellular bugs = Key defense
- intracellular pathogens need cytotoxic T cells to kill the cell and lyse it
--> exposes the intracellular listeria to activated macrophages
- note this is also key that the Cytotoxic t cells also activate macrophages since some intracellular bugs can evade the lysosome destruction if the macrophage isn't activated
-
*Microbiota Bactera = Normal flora
- can produce both Vitamin K and Folate
- when you have overgrowth of bacteria in the intestines, you can be deficient in all the fat soluble vitamins
--> Vit ADE
--> EXCEPT Vit K since the bacteria make it
-
*KEEPS bacteria
- Urease postive organisms
- they are also normally the infecting agents in BURNS victims (+ STAPH CAT)
- "Urease KEEPS the urine and BURNS nice and warm..."
- SS = staph. sapro = urease +
--> urease Positive is the key differentiator for sapro vs epidermidis
-
Gram + vs - key differences
- LPS in Gram -
- THICK peptidoglycan in gram +
-
*Chemotherapy common bacteria
- Mucositis = normal flora of the mouth
--> pseudamonas, strep viridans
- most common sites of large stem cell growth
--> GI enterocytes
--> bone marrow
- Neutropenia
--> common in chemotherapy from the bone marrow disruption
--> stop making IgA = SA and IgG = ospiGINS and neutrophils that are the first line defense against mucosa and GI bacteria
--> only body defense becomes fever
--> fever could be the only sign that you are getting sepsis in a chemo - neutropenic patient
-
*Urease Postive organisms
-
*abscesses
- most are polymicrobial
- they often come from the oropharyngeal normal flora or from the stomach normal flora
-
