cere of budgiesblue-male. red-female.
cere is wrinkled?dehydration
why palpate crop?might regurg/aspirate during exam if not careful
explain avian BCS1=concave(poor prog), 2=flat, 3=convex (ideal), 4=semicircular, 5=beyond keel
what should you feel in celomic palpation?NOTHING normally.... maybe egg, enlarged liver, mass.
mass on to tell if papilloma?blanch with application of acetic acid
FECAL GRAM STAIN: what mag?100x (oil)
what is normal fecal gram stain?150 bacteria/field 70% G+ rod 30% G+ cocci. No budding yeast or gram negative rods. (im positive that a rod of bird poop will be 70% more fun than this test)
how would a carnivorous bird's fecal be different?G- normal for them
what is a borderline malnutrition bird's fecal stain be like?fewer than 150bact/hpf, >90%G+ rod, <10%G+ cocci, occasional G-rod

wing trim--> whats a blood feather, what should you know about ER tx?black shaft- DONT CUT. they will bleed to death. if cut,/broken grab at base and stabalize radius+ulna and then twist and pull
if you're gonna trim a feather, where?at covert line (feathers over bigger feathers)
which feathers do you clip in a large bird, and which in a small bird?in large bird, trim all primaries (ten of them) EXCEPT leave last longest ( 10). Smaller birds, trim secondaries too (bc theyre so light)
"cosmetic" wing clip meanscan glide but no lift

what's unique about raptor blood?Eosinophils
what happens when a raptor has poor nutritional management?they get eosinopenia(they have eosinophils to get this) and heteropenia
which type of birds has smaller RBCs?passarines
largest RBCs?ratities and penguins
avian PCV?43-55
what can basophilic stippling indicate?lead intox, IV hemolysis, erythrocytic ballooning
normal retic amount in blood?2-5%
bird platelets have _________nucleuses
most predominant inflamamtory cell in most sp?heterophil
heteroPHILIA can happen from...stress, corticosteroids, young birds may have more normally
heteroPENIA is associated with what other WBC thingLEUKOPENIA
when would you see heteropenia?(associated with leukopenia) G- infxn, septicemia, circovirus in african greys
explain pseudoheteropeniaheterophils most likely to smuge on blood smear
eosinophilia has been linked to?marked tissue trauma
when would a basophilia be normal?neonate, higher in conures and spectacled amazon parrot
when might basophilia occur?chronic resp. dz or severe stress
which species of birds are lymphocytic (have normally a lot of lymphocytes)amazons, canaries, OWLS (40-70% of total count)
what should you know about most hemoparasites?no tx necessary- tx more hazardous. tx plasmodium if illness occurs
plasmodium (avian malaria)--> looks like? vector? main CS? main necropsy findings?signet. Mosquitos. anemia. splenomegaly. (circular plasma tv)
Leucocytozoon--> which cell does it invade? what does it look like? what is the distribution? what is the vector?**GROSSLY DISTORTS HOST CELL (zoo of weird shaped cells) invades immature RBC or WBC. worldwide distribution except for south/cental america and carbbean (no vectors there).

Question Answer
polyoma is a dz in?budgies, nestlings
polyoma affects ages how?Young birds-high nestling mortality, fledgling morbidity. Adults may be asymptomatic carriers
CS of polyoma?CS: lethargy, fluffed, delayed crop emptying, sudden death
describe carriers of polyomaMany birds without CS will remain viremic and shed virus in their droppings (+/- feather dander and skin)→ become virus-negative (may still have Ab titer)
if budgies survive polyoma, what might happen to their feathers?frech molt (lose primaries and secondary feathers)
if you see a budgie with a french molt...POLYOMA (poly got no feathers, dnt want no crackers)
4 major things you should screen for?polyoma, PBFD, chalmyidophila, pacheckos
polyoma histo?INIB (intranuc inclusion bodies) (polly in the nuc.)
Psittacine Beak and Feather Disease (PBFD)--> what kinda virus?circo (circle around their beak)
what are the clinical signs of Psittacine Beak and Feather Disease (PBFD)? (and what age are affected?)chronic progressive disease in birds over 8-10 months of age-starts with lack of beak and down powder, then progresses to feather loss, abnormal pin feathers (constricted, clubbed, or stunted), abnormal mature feathers (blood in shaft), and eventual necrosis/fracture of distal beak and exposure of bone.... SECONDARY INFECTIONS HIGH
clubbed feathers?PBFD
prognosis of PBFD?Most birds die in 6-12 months, some live years
acute infection of PBFD happens in who? what happens?Acute infection in nestling Cockatoos-regurgitation→ constricting annular feather bands → death
PBFD is common in which birds, how does it usually present?Inf. common in lovebirds and Eclectus parrots, but many have no CS (love eclectic feather dzs)... also, Common in lories with a mortality rate of only ~30%
PBFD Often concurrent infection with..polyomavirus
histo finding with PBFD?INTRACYTOPLASMIC IBs (bc circovirus is RNA) (remember polyoma is intraNUC bc DNA...polly in the nuc cage)
how contageous is PBFD? what's the mortality?SUPER contageous, usually terminal
what should you know about birds positive for PBfd?ALL positive birds are actively shedding virus whether they are showing signs or not.
Pacheco’s Disease (PD)--> what kinda virus?herpes!!! (patchy herpes sores)
is pacheco's acute or chornic? how contageous? how is it transmitted? main CS?ACUTE, HIGHLY CONTAGEOUS, transferred via secretions. Most common CS is sudden death. bright yellow urates with scant feces
bright green/yellow poop?PACHECOS (patchy green and yellow colors)
bollingers bodies?pox (intracytoplasma IBs)
Proventricular Dilitation Disease (PDD)--> what kinda virus?borna virus (BORNA THIS WAY-- with a dilated proventriculus)
PDD usually happens in who? what are the clinical signs?psittacines, mostly african grey parrots. dilation (often massive) of proventriculus (forming a “J” shape and causing the ventriculus to be palpable)--> owner will say crop not emptying for several hrs
J-shape organ on rads and abnormal fecal with seeds in it is what dz?PDD
Viscerotropic velogenic newcastle’s disease caused by what kinda virus?paramyxo (pair-o mixed up Vs)
Viscerotropic velogenic newcastle’s disease (VVND) how contagoues? hows the morbidity? CSs?in <60hrs, DEAD. AND HIGHLY INFECTIOUS. AND CROSSES SPECIES... Significant threat to the poultry industry worldwide
how does newcastle get transmitted?resp aerosols (breathe in the castle air)
*Reportable and zoonotic virusesNewcastle dz, Avian influenza, Eastern equine encephalitis, West nile virus
avian influenza is what virus?orthomyxo (virus for flu...feel like i need orthotics when i have the flu)
natural resivoir for avian influenzA?waterfowl
