dc.description.abstractThe aim of the present study was to isolate, identify and characterize Aeromonas species from raw milk in an around Anand market. A total of 160 samples were processed for estimating prevalence o^ Aeromonas spp. Out of those 160 samples tested, 29 Aeromonas isolates were recovered. On the basis of biochemical characterization 19 (13.6%) isolates of ^. sobria, 6 (4.3%) isolates of A. hydrophila and 4 (2.8%) isolates oiA. caviae were detected in raw milk. When different selective culture media were evaluated for isolation of Aeromonas spp. from raw milk it was found that percent recovery of Aeromonas isolates were more from Ampicillin Dextrin Agar (82.75%) as compared to Aeromonas Starch DNAse agar (62.06%)) All 29 Aeromonas isolates were tested for presence of aerolysin, haemolysin and enterotoxin gene. None of the isolate showed presence of aerolysin and enterotoxin, while overall prevalence of haemolysin gene was 78.78 per cent. In A. hydrophila, 54.54 per cent; A. caviae, 37.5 per cent and in A. sobria, 91.48 per cent isolates were found to possess haemolysin gene. All the isolates of Aeromonas were subjected to antimicrobial dmg sensitivity test against gentamicin, chloramphenicol, ciprofloxacin, kanamycin, bacitracin, rifampicin, tetracycline, ampicillin, penicillin G and erythromycin. Maximum sensitivity pattern was recorded with chloramphenicol (86.20 per cent), bacitracin (31.03 per cent) gentamicin and rifampicin (20.68 per cent) each, erythromycin (17.24 per cent), kanamycin (6.89 per cent). The resistance pattern of Aeromonas isolated from raw milk to various antibiotics was observed as cent per cent resistance towards tetracycline, ampicillin, penicillin G, ciprofloxacin (93.10 per cent), kanamycin (72.41 per cent), bacitracin (68.96 per cent) followed by gentamicin (65.51 per cent), rifampicin (62.06 per cent), erythromycin (58.62 per cent. Owing to the potential hazard of pathogenic Aeromonas spp., it was concluded that it is necessary to put more emphasis on food hygiene. Therefore, the surveillance of potential contaminant is crucial for sustenance of public health.en_US
