This study aimed to estimate the prevalence and clinical presentations of different forms of mastitis and mastitis-causing pathogens in lactating goats in Bauchi, Plateau, and Edo states, Nigeria.
A total of 500 quarters from 250 lactating goats of Red Sokoto and West African Dwarf breeds during the lactation period were clinically examined. Clinical mastitis was detected by gross signs of udder infection during physical examination and abnormal milk, whereas subclinical mastitis (SCM) was recognized using California mastitis test. The bacterial pathogens were identified by morphology, hemolysis, gram staining, and biochemical tests such as catalase, oxidase, coagulase, reaction on sulfite, indole, and motile medium, and fermentation of sugars.
The overall prevalence of mastitis in goats was found to be 101 (40.4%), of which 8% (20/250) were clinical, and 32.4% (81/250) were SCM cases. The quarter level prevalence was 29.4% (145/493), comprising 5.9% (29/493) clinical and 23.2% (116/493) subclinical forms of mastitis. In addition, 1.4% (7/500) of teats were found to be blind on the clinical examination of the udder and teat. Several regional inflammatory reactions and abnormalities in milk were found in 69% and 100% of the cases, respectively. Moreover, some indications of generalized signs such as fever, reduction in appetite, increase in respiration, and pulse rate per minute were recorded in 100%, 75%, 85% and 80% of the cases, respectively. The predominant bacterial isolates recovered were (20.0%), followed by (15.5%) and (11.0%), and the least isolated microorganisms (≤6%) were bacteria of different species including , , , , , , , , , , , , , , , , , , , Typhimurium, , , , , and .
Mastitis continues to be recognized as one of the important health issues and leads to major economic losses to the dairy goats caused by many bacterial pathogens, and the effective measures need to be taken to control the disease.
本研究旨在估计尼日利亚包奇州、高原州和江户州泌乳山羊中不同形式乳腺炎及乳腺炎致病病原体的患病率和临床表现。
在泌乳期对来自250只红索科托和西非矮种泌乳山羊的总共500个乳腺进行了临床检查。通过体格检查时乳房感染的明显体征和异常乳汁来检测临床乳腺炎，而亚临床乳腺炎（SCM）则通过加利福尼亚乳腺炎检测来识别。通过形态学、溶血、革兰氏染色以及过氧化氢酶、氧化酶、凝固酶、亚硫酸盐反应、吲哚和运动培养基反应以及糖发酵等生化试验来鉴定细菌病原体。
发现山羊乳腺炎的总体患病率为101例（40.4%），其中8%（20/250）为临床病例，32.4%（81/250）为亚临床病例。乳腺水平的患病率为29.4%（145/493），包括5.9%（29/493）的临床乳腺炎和23.2%（116/493）的亚临床乳腺炎形式。此外，在乳房和乳头的临床检查中发现1.4%（7/500）的乳头是盲乳头。分别在69%和100%的病例中发现了几种局部炎症反应和乳汁异常。此外，分别在100%、75%、85%和80%的病例中记录到了一些全身症状的迹象，如发热、食欲减退、呼吸加快和每分钟脉搏率增加。分离出的主要细菌菌株为（20.0%），其次是（15.5%）和（11.0%），分离出最少的微生物（≤6%）是不同种类的细菌，包括、、、、、、、、、、、、、、、、、、、鼠伤寒沙门氏菌、、、、和。
乳腺炎仍然被认为是重要的健康问题之一，并且由许多细菌病原体导致奶山羊遭受重大经济损失，需要采取有效措施来控制该病。
