Introduction: Mastitis, the mammary gland inflammation regardless of its reason, is a common disease in female mammals, but is particularly important in the dairy cattle due to its damage to the dairy industry. Mastitis may also transmit to the other livestock, and in humans, the consumption of affected products can lead to the streptococcal pharyngitis. The purpose of this study was to identify causative bacterial agents of bovine mastitis for preventive and treatment purposes, and ultimately to reduce economic losses.
Materials & Methods: Using standard methods, 32 dairy cows were randomly sampled the province of Ilam. The samples were transferred to the laboratory and were then cultured in common medium. And after that, the gram staining was performed. To identify the bacteria genus and species, the samples were cultured in specific media.
Findings: Of the 32 randomly selected cows, 26 cows (81.25%) were severely contaminated with Klabsiella pneumonia and Escherichia coli, and in addition one farm was also contaminated with Strept-ococcus agalactiae.
Discussion & Conclusion: Considering that the farmers are unaware of the high degree of the bacterial infections, it is safe to say that the alarm bells are ringing in relation to the economic burden of mastitis in the province of Ilam.
