Mycoplasmas from donkeys and horses in the Sudan

Abstract

Seventeen isolates (4.27 %) were recovered from 398 samples. Twelve isolates (4 %) were obtained from 300 donkey nasal swabs, three (4.3 %) and two (6.89 %) isolates were recovered from 69 horse nasal swabs and 29 mare uterine washings, respectively. Nine isolates were lost during storage at — 20°C and the remaining eight were identified as mycoplasmas and their biological, biochemical and serological reactions were investigated. The isolates could be divided into two groups on the basis of glucose fermentation and arginine hydrolysis. The first group neither fermented glucose nor hydrolysed arginine. Organisms in the second group hydrolysed arginine only.
