Abstract

Mastitis is one of the most important diseases for the dairy industry worldwide due to the great economic losses it causes, and the bacterial agents that it causes variation from one herd to another. The objective of the investigation was determined the infectious agents involved in the development of mastitis in specialized dairies herds in the Highlands of Boyacá, Colombia. Was performed CMT tests in 4432 teats to determine the positive results for inflammation (CMT + 2), sampling in aseptic material of positives quarters, identification and differentiation of through microbiological cultures, Gram staining, and biochemical tests of bacterial and fungal agents presents in milk samples. It was determined that prevalence´s varied between the years of the study, in 2016 there was a total prevalence of 45.19%, in 2017: 51.06% and in 2018: 39.76%. The months of April, May, and September, October presented the highest number of teats affected with mastitis during the three years of study. Streptococcus agalactiae and Staphylococcus aureus were the most prevalent microorganisms that cause mastitis in the three study years. There was an increase in the prevalence of infected teats corresponding to the months (April, May, September, and October) due to rainfall increases. The contagious pathogens were most prevalent that environmental pathogens.
引起博亚卡高原奶牛乳腺炎的细菌和真菌感染性病因(哥伦比亚)
乳腺炎是世界范围内乳制品行业最重要的疾病之一,因为它造成了巨大的经济损失,而且它引起的细菌制剂在不同的群体之间发生了变异。调查的目的是确定与哥伦比亚博亚卡高地专业奶牛场乳腺炎发展有关的传染源。对4432个乳头进行了CMT测试,以确定炎症阳性结果(CMT+2),阳性部位的无菌材料取样,通过微生物培养物的鉴定和分化,革兰氏染色,以及牛奶样本中细菌和真菌制剂的生化测试。研究发现,不同年份的患病率各不相同,2016年的总患病率为45.19%,2017年为51.06%,2018年为39.76%。在三年的研究中,4月、5月和9月、10月的乳腺炎发病率最高。在三年的研究中,无乳链球菌和金黄色葡萄球菌是导致乳腺炎的最常见微生物。由于降雨量的增加,与月份(4月、5月、9月和10月)相对应,受感染乳头的患病率有所增加。传染性病原体比环境病原体更为普遍。
