Extraintestinal Infections by Enterobacteriaceae Flashcards
Extraintestinal Infections by Enterobacteriaceae in Companion animals (3)
genitourinary tract infections (UTI) in dogs and cats
septicemia shock in neonatals
opportunistic infections: wound, skin, ear
Extraintestinal Infections by Enterobacteriaceae in Poultry
Colibaciolisis
Extraintestinal Infections by Enterobacteriaceae in FIsh
Edwardsiellosis
Most common pathogen in canine and feline UTIs
E. coli (some Proteus mirabilis and Klebsiella pneumoniae)
Are UTIs usually mixed infections?
Nope!
typically one species, can be two; three indicates probable contamination of the urine sample
UTI treatment
Amoxi/Clav or SMZ/TMP is best; fluoroquinolones as second-line
pyometra
pus in the uterus caused by an ascending infection of E. coli from the vagina
Septicemic Shock in Neonates from E. coli
due to CNF1 or CNF2 cytotoxins, can die before symptoms appear (peracute)
Colibacillosis
a localized or systemic bacterial infection due to E. coli in poultry resulting in deposition of fibrinous exudate in the thoracic & abdominal cavities, &/or the air sacs, joints, eyes, reproductive tract, meninges
Do you treat colibacillosis with antibiotics?
not recommended due to widespread resistance
Edwardsiella
inhabits freshwater environments and intestinal tracts of cold-blooded animals
“hole-in-the-head” lesion
chronic Edwardsiella ictaluri in catfish in SE US
Edwardsiella tarda
catfish, Japanese eels (red disease), and flounder; not very common in the US
Edwardsiella vaccine?
yes (becoming more resistant to antibiotics)
Yersinia pestis
the plague! transmitted by fleas, rodents are the reservoirs
