Abstract

This study was conducted in Udaipur city of Rajasthan, and aimed to analyse the antibiogram of Bacillus cereus isolated from dairy products. A total of 160 samples, including raw pooled market milk (n=20), ice cream (n = 20), milk powder (n = 20), pasteurised milk (n = 20), paneer (n = 20), dahi (n = 20), khoa (n = 20), and butter (n = 20), were processed for the isolation, identification, and antibiotic susceptibility pattern of Bacillus cereus. All the isolates from milk and milk products were tested throughout the trial for susceptibility to a total of 12 different antibiotics. The antibiogram study showed that all the isolates had 100% sensitivity to amikacin and 100% resistance to ampicillin (100%), methicillin (100%) and penicillin-G (100%). The main challenge regarding in this study is that since milk is a perishable thing so we have to quickly analyse the samples and it is also used to make variety of products, so we need to collects large number of samples to know the antibiogram pattern.

Keywords

Bacillus cereus, milk, milk products, antibiogram, resistance, sensitive

Conclusion

It was determined that the high amount of Bacillus cereus contamination in milk and milk products poses a risk to human consumption. The widespread use of antibiotics as a growth stimulant in animals creates bacteria that pose a risk to the public's health. As a result of the findings, more has to be done to improve the hygienic conditions for milk production, processing, and packing.
