Q2 POULTRY Flashcards
turkey hemorrhagic enteritis
adenovirus, young turkeys, intestines hemorrhaged and distended by blood, splenic pallor
marble spleen disease
adenovirus of pheasants, acute respiratory distress and friable splenomegaly
quail bronchitis
adenovirus that causes catarrhal tracheitis
avian encephalomyelitis
picornavirus causing fine tremors and ataxia in young chicks and decreased egg production in adults, cataracts and white spots on stomach
fowl plague
influenza virus A, can be low pathogenic or high strains, high causes hemorrhage of feet and comb, kinda everything too
avian leukosis vs mareks disease
leukosis (retrovirus) is b cells and causes bursal lymphoma, mareks (herpes 2) is t cells and causes neuropathy
signs of mareks disease
lymphoma everywhere, infiltrated iris, and ballet dancer posture
chicken infectious anemia
circovirus destroys hematopoetic cells and t cells
duck plague
AHV-1, targets waterfowl and causes phallus prolapse and intestinal diphtheric membranes
fowl pox
poxvirus, wet vs dry form on mucous membranes or skin
trichomoniasis
protozoal parasite that also causes ulcerative stomatitis
infectious laryngotracheitis
GHV-1, trachel/glottis occlusion with fibrin and necrosis causes neck extended, pump handle stance, reportable
infectious bronchitis
coronavirus, respiratory, reproductive and renal lesions, reportable
IBD
birnavirus with high morbidity, destroys b lymphocytes in bursa
newcastle disease (three types)
paramyxoviridae with lentogenic, mesogenic, and velogenic (high mortality and neuropathy, cecal tonsils necrosis
ZOONOSIS
fowl cholera
Pasteurella multocida causes necrohemorrhagic hepatitis, chronically fibrin exudate in wattle, reportable
colibacillosis
FESSE
Fibrinoheterphilic
Environmental
Secondary
Septicemia
E. coli
clostridial diseases in chickens
septicum causes skin form and perfringens causes skin and intestinal form, turkish towl necrosis from rations with wheat
clostridial diseases in turkeys
septicum and perfringens cause skin disease from wet litter
clostridial diseases in quail
colinum causes hepatointestinal disease with close to 100% mortality
erysipela
E. rhusiopathiae causes hemorrhage and septicemia in turkeys, ZOONOSIS
three types of mycoplasmosis
M. gallisepticum: serocatarrhal infraorbital sinusitis, reportable
M. synoviae: tenosynovitis
M. meleagridis: turkey specific and causes serofibrinous airsacculitis (venereal)
infectious coryza
Avibacterium paragallinarum in chickens, thick fibrinocaseous exudate from infraorbital sinus
Salmonellosis
cecal plugs and bronze liver, reportable
racoon eye/ turkey coryza
Bordetella avium in young turkeys causing tracheitis and voice change
ascariasis vs pediculosis
mites at feather extremity vs lice at feather base
scaley-leg mites
Knemidocoptes mutans spends whole life cycle embedded in host skin
what 5 viruses all cause respiratory signs and tracheitis?
infectious laryngotracheitis, fowl pox, infectious bronchitis, newcastle, and HPAI
three types of capillariasis
obsignata: small intestine
annulata: crop with indirect life cycle
contorta: crop
gape worm
Syngamus trachea, intraluminal bright red adults
Eimeria tenella
necrohemorrhagic typhlitis/colitis, big blood clots in lumen
cecal worms
Heterakis gallinarum, important vector of Histomonas meleagridis, which causes enterohepatitis
brooder pneumonia
aspergillosis (fumigatus) causes granulomatous airsacculitis, can infect eggs directly or through litter and feed
curled-toe paralysis
hypovitaminosis B2
crazy chick disease
vitamin E deficiency causes cherry cerebellum
cerebellar encephalomalacia and muscular dystrophy
ascites syndrome
since we select for rapid growth, essentially induces hypoxia because lungs and heart can’t keep up, failure of the RV and muscular AV valve, right sides heart failure
green muscle disease
overexertion causes compartment syndrome
what is an important sequelae of hepatic lipidosis in birds
hemorrhage and fatal hemocoelom
