Urinary and Repro Flashcards
in general, what commensals are part of the normal microbiome in cat and dog urinary tracts
Gram negative and positives, mycoplasma, aerobes, anaerobes
describe typical small animal UTI signalment
more common in dogs, female, older
what is the most common UTI bacteria in small animals
EPEC (uropathogenic E. coli)
define cystitis
inflammation* of bladder, usually from ascending infection of urethra
define pyelonephritis
infection of kidneys, usually from ascending infection of ureter
name any 3 common clinical signs of cystitis
dysuria, pollakiurua, stranguria, hematuria, caudal abdominal pain
name any 3 common clinical signs of pyelonephritis
kidney or flank pain; possible fever, vomiting, polyuria, and/or polydipsia (PUPD especially if chronic)
what is the preferred method to diagnose a UTI
culture of bladder urine by cystocentesis; male dogs can be catheterized if cystocentesis fails/bladder not palpable
describe morphology, biochemical tests, and basic ecology of genus Corynebacterium
Gram-positive, rod-shaped pleiomorphic, aerobic or facultative aerobic, host specific to cattle; they are obligate symbiont bacteria (normal in lower urogenital tract and prepuce) but opportunistic pathogen of urinary tract and kidneys
in increasing order virulence, what are the three virulent strains of Corynebacterium in cattle
Corynebacterium pilosum < C. renale < C. cystitidis
what percentage of Corynebacterium UTI cases are fatal in cattle
25-30% (note typical herd incidence 1%)
how can Corynebacterium UTI be diagnosed
urinalysis (blood, protein, leukocytes) with clinical sings or urine culture and isolation
how can Corynebacterium UTI be treated
2-4 weeks antibiotics if acute infection; later, harder to reach bacteriia in pus and in chronic cases kidneys irreversible damaged
what would pyelonephritis look like upon gross post-mortem exam
usually one kidney affected and enlarged; granular renal cortex with hemorrhage and abscess; chronically calculi resent in renal calyces and in thickened fibrotic ureter; thickened bladder; purulent exudate
how do clinical signs differ between acute and chronic cystitis pyelonephritis
cystitis: frequent painful urination, hematuria, proteinuria, colic, fever. pyelonephritis, acute: fever, anorexia, abnormal posture, hematuria, polyuria. chronic pyelonephritis: weight loss, anorexia, decreased milk production
