Identification and antibiogram pattern of from the milk and milk products in and around Jammu region.

AIM

The aims of the present study were to assess the prevalence, identification, and antibiogram pattern of from 215 samples of different milk and milk products in and around Jammu region.

MATERIALS AND METHODS

In the present study, 215 samples of milk, rasgulla, burfi, rasmalai, kalaari, paneer, ice cream, and pastry were collected and analyzed for the isolation of the using PEMBA, and antibiogram pattern was observed for all the milk and milk products.

RESULTS

was detected in 61/215 samples with an overall prevalence of 28.37%. Biotyping revealed predominantly 5, 7, and 2 biotypes in raw milk. Burfi and ice cream revealed 2, 3, 5, and 7 biotypes. Rasgulla had 2, 3, and 5 biotypes; paneer and rasmalai had biotypes 2 and 5, while kalaari revealed biotype 5. Antibiogram pattern revealed that isolates were highly sensitive to gentamicin (100%), intermediate to ampicillin (40.98%), tetracycline (31.14%), erythromycin (29.50%), and amoxicillin (26.22%), and high resistance against penicillin G (100%). Adulteration of starch was detected in 16.66 % raw milk samples. All starch positive samples were positive for . . However, 12 starch negative samples also yielded . .

CONCLUSION

From this study, it was concluded that highest prevalence of . was found in ice cream. Several isolates of showed toxigenic activity, so the presence of in milk and milk products may be of public health hazard. The antibiogram pattern of isolates showed sensitivity to gentamicin, ciprofloxacin, chloramphenicol, streptomycin, and resistance to penicillin-G and cephalexin. The presence of in milk and milk products showed a strong association besides establishing the fact that starch adulteration can be indicative of the presence of .
