18
Q

Leydig cell tumor

A

yellowish, firm-semi firm, +/- hemorrhage

benign - only sign it’s there is when it gets big

19
Q

Sertoli cell tumor

A

dogs, budgies get avian form
Firm, fibrous, doesn’t bulge on cut, pale tan
produces estrogens (alopecia, benign prostatic hyperplasia, gynecomastia)
Inhibins cause atrophy of contralateral testicle (decreased testosterone)
Usually benign, things normal when removed
most common tumors in cryptorchid

20
Q

Seminoma

A

most common testicular tumor in stallions
Round cell tumor of testis
soft, tan to pink, bulges on cut section

21
Q

Prostatic neoplasia

A

urothelial carcinoma common in dogs >10 yrs
prostatic adenocarcinoma rare in dogs, common in hum
often aggressive, metastatize
castration increases risk

22
Q

enzootic posthitis/balanoposthitis

A

pizzle/sheath rot
rams
C. renale
Increased protein in diet –> increased urea, hydrolyzed by c. renaled –> ammonia causing local irritation

23
Q

Masculinization

A

XY, Sry gene –> TDF (testis determining factor) –> sertoli cells develop –> testosterone = wolfian duct becomes male parts, Anti-mullerian hormone = no feminization

24
Q

Kleinefelter syndrome

A

XXY

tortoise shell or calico - only female cats

25
Q

Which is true intersex? Chimera or freemartinism

A

chimera

26
Q

XX sex reversal

A

intersex syndrome in goats
true hermaphrodites - have M & F gonads due to loss of FOXL2 gene (F sex determining gene in goats)
also in american cocker spaniels

27
Q

Male genotype, Female phenotype

A

XY, Sry +, has testes, but no androgen/testosterone receptors = external genitalia is mostly vestigial - femaleish

28
Q

Persistent mullerian duct syndrome (PMDS)

A

XY, Sry +, has testes, male phenotype
but no AMH production, so mullerian duct doesn’t regress - get uterus, probably undescended testicles, penis
Prone to muco or hydrometra
Mini schnauzers

29
Q

Mummification vs. maceration which one involves bacteria?

A

Maceration

30
Q

Diagnostic trifecta for abortion cases

A

placenta
fetus
maternal serum

31
Q

Equine, Camels, Pigs have diffuse placentation - what length of coiled/twisted umbilical cord is considered normal?

A

<84 cm. If greater than, pathologic

32
Q

what bacterial abortive infections are intracellular

A

brucella
coxiella
chlamydia
Listeria in fetus

33
Q

late term abortion nephritis, hepatitis

A

leptospira

34
Q

what bacteria can cause abortion at any stage of pregancy

A

campylobacter

35
Q

target lesions, necrotizing hepatitis

bronchopneumonia

A

campylobacter

36
Q

Mummified piglets

A

PRRS
Porcine circovirus - 2
PArvo

37
Q

Porcine circovirus - 2

A

placenta - no lesions

fetus gets myocarditis w/ early to mid-gestation infection

38
Q

timing of porcine parvovirus

A

a. <30 days gestation = embryonic death
b. 30 – 70 days = mummification
c. >70 days = no lesions

39
Q

viruses that cause abortion in cattle

A

BVDV (pestivirus)

BHV-1 - abortion storms in naive cattle

40
Q

intra-nuclear viral inclusion bodies in adrenal gland

A

BHV-1

41
Q

viruses that cause abortion in EQ

A

EHV-1 (fetus, placenta fresh)

Equine viral arteritis

42
Q

CHV-1 and puppies

A

<3 wks old

weak, multifocal renal hemorrhage

43
Q

“cupping” of placenta

A 
Mycotic abortion (aspergillus, zygomycetes)
also see mycotic dermatitis
44
Q

Neospora caninum

A

cattle
mid-term abortion
see oocysts in canine feces
necrotizing myocarditis in fetus
