Bacteria And Health
Pathogens (causes diseases)
STDs
Neisseria gonorrhoeae
Gonorrhea
Pelvis inflammation disease (PID)
Ectopic pregnancy
URINARY TRACT INFECTION
Escherichia coli
Chlamydia trachomatis
Treponema pallidum
Syphilis: Skin lesion on genitals
Contact disease
Mycobacterium Leprae
Drug: Dapsone
Attack nervous system
Nerve damage
Loss of pain sensation
Leprae/Hansen's disease
URINARY TRACT INFECTION
Eg:
Escherichia coli
Chlamydia trachomatis
Pathogens (Cause diseases)
Food/water borne
Salmonella typhi
High resistance to environmental condition
Thypoid fever
In small intestine: Deep ulcers, bloody stools
Vibrio cholerae
Cholera: Diarrhea
Disrupting body's water balance
Oral rehydration solution
Staphylococcus aureus
Nausea, vomiting, diarrhea, cramps
Produce enterotoxin (In GI tract)
Helicobacter pylori
Peptic ulcers
Resistant to stomach acid (-ve pH tolerant)
Bloody stools
Soilborne
Bacillus anthracis
Causes Anthrax
Symptoms: Organs filled with bloody black fluid
Spore-forming (Use as biological weapon)
Clostridium tetani
Tetanus: Toxin invaded nervous system, develop in hours
Vaccine: Anti-tetanus serum
Spore-forming, produce tetanospasmin toxin
Pathogens (cause diseases)
Airborne
Upper RT
Corynebacterium diphtheria
Diphtheria: Exudates in throat, causes deaths in infants
DTP vaccines: to neutralize the toxins.
Bordetella pertussis
Pertussis (Whooping cough)
Potential pneumonia
Toxins paralyzes ciliated cells, impairs mucus movement
DTP vaccine
Streptococcal pyogenes
Have substance called M protein, produce toxin erythrogenic
Symptoms
Rheumatic heart disease: Heart valves distorted and scarred
Glomerulonephritis: Kidneys manifestation
Rheumatic fever: joint pain and inflammation
Scarlet fever: strep throat with skin rash
Septicemia (Septic shock): Death
Neisseria meningitidis
Meningitis
Affects the membranous covering of the brain and spinal cord
Shows influenza-like effects
Sepsis
Streptococcal pharyngitis
Strep throat: High fever, sore throat, swollen tonsils.
Otitis media: Middle ear infection
Haemophillus influenzae
Influenza
If the bacteria move from RT to blood, then meninges (CNS) causing meningitis (called Haemophillus meningitis)
Lower RT
Mycoplasma pneumoniae
Pneumonia
Rarely fatal
Klebsiella pneumonia
Pneumonia
Streptococcus pneumoniae
Pneumococcal pneumonia
High fever, chest pains, breathing difficulty
Clostridium botulinum
Produce batulism toxin
Causing muscle contraction
Result: Paralysis (In lung, difficulty breathing)
Tuberculosis (TB)
Early Detection: Mantoux Test
Multidrugs therapy:
Ethambutol, Streptomycin, Rifampin, INH,
Pyrazinamide.
Symptoms
Chronic cough, chest pain, expel sputum
Vaccine
BCG: Bacille Calmetter Guerin
