Abstract

The inflammatory disease of the mammary gland known as mastitis has many different possible sources of infection such as bacteria, fungi or other causes. Dairy cattle that are affected by mastitis can suffer financially from decreased milk production and poor milk quality, thus it is necessary to provide effective prevention and treatment methods for mastitis within the dairy industry. The objective of this research was to isolate and identify those bacterial pathogens responsible for causing bovine mastitis in dairy cattle suspected of being infected. Twenty milk samples were obtained from dairy cattle that were believed to be suffering from bovine mastitis. All twenty samples were then tested using bacterial cultures with selective and differential media. Following testing with conventional microbiological techniques, the VITEK 2 Compact system was used to verify the bacterial identification. Out of the twenty milk samples tested, eighteen samples (90%) demonstrated some form of bacterial growth, whereas only two samples (10%) showed no evidence of any type of bacterial growth. The most common bacteria isolated out of 18 different bacterial strains was Escherichia coli, which accounted for 38.88% of all isolates, followed closely by Staphylococcus aureus, accounting for 33.33% of the total, Klebsiella pneumoniae, accounting for 11.11% of the total, Aeromonas veronii, accounting for 11.11% of the total, and Rahnella aquatilis, accounting for 5.55% of the total. Bacterial pathogens were identified in most of the cow's milk samples tested that were suspected of developing mastitis. Escherichia coli and Staphylococcus aureus were identified as the two primary bacterial strains present in the milk samples. Isolation of bacteria and identification of the bacteria can assist with diagnosing, preventing, and managing bovine mastitis.
