乳房炎和抗菌素耐药性是撒哈拉以南非洲乳制品行业面临的一大挑战。一项研究在(乌干达)基鲁胡拉区的卡松吉县和克松加县进行，那里的政府和私营部门有刻意的计划来提高牛奶及其产品的生产效率、质量和安全性。这项研究旨在确定乳房炎的患病率、其常见病原体、引起乳房炎的微生物的抗菌素敏感性以及加工乳制品：酸奶和酥油的污染物。从九个农场采集了71份牛奶、14份酸奶和3份酥油样本。在71头接受测试的奶牛中，54头(76.1%)患有乳房炎。克松格尔族乳房炎病例32例(59.3%)，克松吉州乳房炎22例(40.7%)。常见的乳房炎病原体为葡萄球菌。(30.8%)、链球菌属。(12.3%)、棒状杆菌属(15.4%)、大肠杆菌(7.7%)。部分菌株对四环素和青霉素耐药。酸奶中常见的污染物是葡萄球菌。(8.3%)、链球菌属。(8.3%)，棒状杆菌属。(8.3%)和大肠埃希菌(8.3%)，而所有酥油都含有链球菌。(100%)。乳房炎、抗菌素耐药性和奶制品污染的患病率在研究地区很高。建议有针对性的预防和控制乳房炎以及抗生素耐药性的计划。
Mastitis and antimicrobial resistance are a big challenge to the dairy industry in sub-Saharan Africa. A study was conducted in Kashongi and Keshunga subcounties of Kiruhura District (in Uganda) where the government and private sector have deliberate programs to improve production efficiency, quality, and safety of milk and its products. The study aimed to determine the prevalence of mastitis, its common causative agents, antimicrobial sensitivity of mastitis causing organisms, and contaminants of processed milk products: yoghurt and ghee. Seventy-one milk, fourteen yoghurt, and three ghee samples were collected from nine farms. Of the 71 cows tested, 54 (76.1%) had mastitis. The mastitis cases from Keshunga were 32 (59.3%) and Kashongi contributed 22 (40.7%) of the cases. The common mastitis causative agents were Staphylococcus spp. (30.8%), Streptococcus spp. (12.3%), Corynebacterium spp.(15.4%), and E. coli (7.7%). Some of the isolates were resistant to tetracycline and penicillin. Prevalent contaminants of yoghurt were Staphylococcus spp. (8.3%), Streptococcus spp. (8.3%), Corynebacterium spp. (8.3%), and E. coli (8.3%), whereas all ghee contained Streptococcus spp. (100%). Prevalence of mastitis, antimicrobial resistance, and contamination of milk products are high in the study area. Targeted programs to prevent and control mastitis as well as antibiotic resistance are recommended.
