Abstract

Rhodococcus equi (R. equi) is asignificant pathogen with equines being the most susceptible host. This facultative intracellular pathogen is quite stable in nature and contaminates equine environments. In this paper aimed to antibiogram study of R. equi. Out of 220 samples processed 37 isolates were found to be R. equiin out of 75 Rhodococcus sp. All the 37 isolates of R. equi were subjected to resistotyping with 16 different antibiotics. All isolates of R. equi showed 100 percent sensitivity to Gentamicin followed by ciprofloxacin and streptomycin (sensitivity-97.30%) while higher resistance i.e. 97.30 percent to furazolidone and 59.46 percent to sulphadiazine was observed.

Keywords:
Rhodococcus equi, antibiogram, sensitivity, gentamicin
