ISOLAT？ON OF BACTER？AL AGENT FROM D？ARRHEA W？TH FOAL AND ANT？B？OT？C SUSCEPT？B？L？TY

INTRODUCTION: Diarrhea in foal can cause serious infections to death. In this study, the determination of microor-ganisms and antibiotic susceptibility of isolated bacteria in fecal swab samples collected from foals with diarrhea were aimed. METHODS: Sixty-eight strains were isolated from all of samples. The agents were isolated and identified with conventional methods. RESULTS: The organisms were isolated in pure culture from 59 (86.76%) samples and were isolated in mixed culture from 9 (13.23%) samples. Citrobacter spp. (44.11%) was the most frequently isolated agent. Also, Escherichia coli (30.88%), Klebsiella oxytoca (8.82%), Staphylococcus spp. (5.88%), Micrococcus luteus (4.41%), Streptococcus zooepidemicus (1.47%), Acinetobacter calcoaceticus (1.47%), and Pseudomonas aeruginosa (1.47%) were isolated, res？pectively. This bacterial agents were found susceptible nitrofurantoin, enrofloxacin, ampicillin-sulbactam, gentamycine, amoxicillin-clavulanic acid, respectively. DISCUSSION AND CONCLUSION: It is very important to apply the necessary antibiotic and supportive treatment to determine the cause of the fever which is very economically valuable and to control the diarrhea. There is a need for further research in this regard
