ABSTRACT
Tahamtan Y, Mirghafari H, Hayati M.,
Characterization of Pasteurela multocida
associated with pneumonia in small ruminants, Onl J
Vet Res., 17 (3): 151-158, 2013. M. haemolytica and P. multocida isolated
from 750 sheep and goat throat and eye swabs were evaluated for biochemical,
antibiotic sensitivity, mice lethality and prevalence. Thirty four (4.47%) P.
multocida isolates were positive to oxidase,
catalase, indole production, glucose and lactose
fermentation. Isolates produced non-haemolytic
colonies on blood agar and failed to grow on MacConkey agar. Six isolates induced mortality in mice with a short mean
dead time (MDT) in 18%. All isolates were resistant to oxytetracycline and erythromycin, but sensitive to penicillin
and slightly sensitive to trimethoprim. Prevalence was highest in spring and
late summer. Isolates with short MDT induced severe pneumonia.
