Biotyping of Gram positive and negative bacteria from milk sample

Food contains high-risk pathogens and is the primary cause of human illnesses. To verify the presence of dangerous bacteria, food safety must be assessed. These studies have revealed a promising role in identifying  various milk and dairy samples. The information gathered from this study may serve as a foundation for the prompt detection of foodborne bacteria in the food industry. Using culture-dependent microbial techniques, the variation of lactic acid bacteria (LAB) species in milk was investigated in order to determine the prevalence and antibiotic sensitivity of Campylobacter species present in raw milk. Agar media, which is commonly used to count LAB, was used to obtain dominant strains. Arcobacter butzleri, a novel zoonotic foodborne pathogen associated with enteritis and occasionally causing bacteremia in humans, was added to the milk samples to increase the amount of acidifying LAB present. This bacterium's biotyping is essential for determination. The enzymatic patterns of Lactobacillus delbrueckii and Streptococcus thermophilus were identified using the quick APIZYM method.  Alkaline and acid phosphatase, naphthol-AS-BI-phosphohydrolase, esterases, glycosidases, peptidases, and proteases (trypsin and chymotrypsin) were among them. Eating at restaurants can cause foodborne illnesses, but there are many ways that cross-contamination can occur. These include grocery stores, farmers' markets, secondary food production involving food processing and manufacturing, transportation, storage, and distribution, and primary food production from farm plants and animals during the harvesting or slaughter of food animals. In addition, homes, restaurants, and other foodservice establishments prepare and serve food Considering the various phases
