A survey of selected causative organisms of bacterial mastitis in Zebu-Holstein dairy cows was carried out on four herds in Wondogenet. Pathogens were found in 39% of udder quarters and mastitis in 16% of quarters. The main mastitis causing organisms isolated were Staphylococcus aureus (47%), Streptococcus agalactiae (15%) and Streptococcus uberis (31%). It was indicated also that udder quarters with micrococci would be less susceptible to infections by pathogenic organisms.
对翁多杰内特的四个牛群中的泽布-荷斯坦奶牛细菌性乳腺炎的选定致病微生物进行了一项调查。在39%的乳房象限中发现了病原体，16%的象限发生了乳腺炎。分离出的主要引起乳腺炎的微生物是金黄色葡萄球菌（47%）、无乳链球菌（15%）和乳房链球菌（31%）。研究还表明，带有微球菌的乳房象限对致病微生物感染的易感性较低。
