Isolation and Identification of Gram-Negative Bacteria on Cattle Farms Indicated by Mastitis

Mastitis is one of the causes diseases that can reduce livestock production. be caused by various types bacteria cause a decrease in production difficult to cure with antibiotics has been reported resistance. This study aims determine gram-negative mastitis cows. The used samples taken from folk farms means udder swabs. Bacterial isolation carried out planting Mannitol Salt Agar (MSA) media and identifying Gram staining biochemical tests (maltose lactose). data analysis descriptive analysis, namely as causative agents mastitis. results obtained species Klebsiella sp Enterobacter yang classified Gram-negative bacteria. It concluded cows indicated there are bacteria, these morphologically identified, sp.
