ANTIBIOTIC SUSCEPTIBILITY OF SOME PATHOGENIC BACTERIA ISOLATED FROM BOVINE FRESH MILK IN AL-HILLA CITY.

The aim of this study was antimicrobial susceptibilityof some pathogenic bacteria isolated from fresh bovine milk Al-Hilla city. A total of 40 milk samples were collected randomly from Hilla city. Isolation of E. coli, Staphylococcus aureus and Shigella spp. were done by using enrichment media and selective media. The present study showed the levels of contamination with E. coli bacteria were isolate 15(37.5%), Staphylococcus spp. was isolated 18(45%) and Shigella spp. were 8(20%), respectively from bovine fresh milk. Antimicrobial susceptibility testing to E. coli, Staphylococcus aureus and Shigella spp. were conducted for Cephalothin,Imipenem,Gentamycin, Erythromycin, Ciprofloxacin andMeteronidazol respectively. The result of the present study shows that E. coli isolates were sensitive to Ciprofloxacin Imipenemand Gentamycin, respectively. Also in this study the high resistance of E. coli isolate to cephalothin and metronidazole. The present study showed high sensitive of Staphylococcus spp. was observed to gentamycin, Ciprofloxacin and imipenem respectively. Also in our study showed that high resistance to Erythromycin, Cephalothin and metronidazole respectively from bovine fresh milk. In present study, isolate of Shigella spp. showed highly sensitive to gentamycin, ciprofloxacin and imipenem respectively. However, in current study showed that Shigella spp. isolated resistance to Metronidazole and cephalothin respectively from bovine fresh milk. Antimicrobial susceptibility should be conducted before treating bovine milk. Consequently, reduction in transfer of resistant S. aureus, Shigella spp. and E. coli between humans and animals.
