Avian, Nu - Coggle Diagram

- - - - Dermanyssus gallinae ---> nocturanal feeders, sever infestations --anemia & death. Present in feathers
    - - Knemidocoptes affect chickens, phesants & pigeons occurs unfeathered parts due to irritation can lead to feather picking -> lesions- thickened & encrusted (female-short legged)
    - - Laminocoptes cysticola Subcutaneous mite--> 1-3mm nodulae SC lesions (die in a cyst in collagen & calcifies)
  - - - Rx- Amprolium- 0 withdrawal time, Sulfaquinoxoline- 10d, Sulfadimethoxine -5 day, Nicarbazin -4 days, Robenidine - 5 days
  - - - Eosinophilic intracytoplasmic inclusion bodies (Bollinger bodies) in epi cells. Spread- contact & mosquito vector
      - Dry form- warts, nodules or scabs in unfeathered areas of head, legs & vent. (slow progress) Wet form--diptheritic lesions in oral cavity(pharnx, mouth) & respirator tract. No Rx & sanitary & single vaccine can use to control
    - - increase T by 5 degree
    - - reservoir -wild waterfowl (gull), duck, geese
    - - Marek's ds
        
        C/S progressive paralysis & paresis Affect sciatic nn & cause vasogenic brain edema. tumors in organs-renal
        
        vaccine - in ovo injection of live virus at 18day of incubation. (6wks start the ds)
        
        nn, skin & organs tumors
      - Reticuloendotheliosis (retrovirus)
        
        cause acute neoplasia & chronic B & T cell lymphoma cause runting of ds
        
        Runting syndrome (malabsorption syndrome)
        
        weight loss, paleness, abnormal feathering & occasional paralysis PM- thymic & bursal atrophy, enarge nn & anemia neoplasia liver, spleen, intestine & heart. Dx viirus isolation or Ab detection
        
        1-3 wks old chicks, multifactorial eitiology cull affected birds PM- decrease pigmentation of skin, feet, & beak & broken or twisted feathers. **PM-orange mucus in SI, enlarged proventriculus, a small gizzard & an atropied pancreas
      - Lymphoid leukosis
        
        basophilic inclusion bodies in hear mm--> retro virus -- enlarge liver, spleen tumors in organs & mm
        
        16 wks start ds &slow progression <5% death
    - - greenish diarrhea, ulcers in proventriculus, cecal hemmorrhages
    - - reduce egg prodcution, respiratory signs--> PM- hemorrga in trachea, mucus plud in larynx, eosinophilic intranuclear inclusion bodies in epi cells, epithelian cell hyperplacia (synsitial cells)
      - Dx- virus isolation, crowdry type inclusion bodies in tracheal epi **Vaccinate the flock - modified or recombinant vaccines)
  - - - 3 PM lesions 1. Fibrinous pericarditis, 2. perihepatitis & 3. airsacculitis. fecal contamination, gain access to blood stream via respi tract or intestines. cause septicemia if survive - develop 3 lesions with lymphocytic destruction of bursa & thymus
    - - inhabitant in skin & mucosa --> transmit during skin trauma
    - - out breaks occur during hot weather due to alkali & anerobic conditions occur in stagnated water. **So waterfowls die or cannot move, PM- no gross lesion
      - Rx- nursing care & supportive care --> can walk bt cannot fly / prevention - oxygenation /vaccination type C
    - - Cause Avian tuberculosis - lost weight, thin, sluggish, PM- multiple solid-to-soft crumbly, gray nodules (<1mm to cm)embedded in several organs & tissues including liver, spleen & intestines
      - Acid-fast bacteria
  - - - quarantine & disinfect the pen
      - inhalation of fungal spores cause yellow to tan nodules in the lungs inhalation of fungus --> cause granulomatous pneumonia
- - - - Clostridium colinum affect bob white quail control- quarantine & disinfect pen
