Abstract

The objective of our study was to evaluate prevalence of selected bacterial and fungal pathogens of mastitis in dairy cattle in north-eastern Poland. Our study was conducted from 2013 to 2019 in 1,665 clinically and sub-clinically infected quarter milk samples (2013, n = 368; 2014, n = 350; 2015, n = 290; 2016, n = 170; 2017, n = 173; 2018, n = 224; and 2019, n = 90). The isolation and identification of the pathogens were performed in keeping with generally accepted microbiological procedures. In 2013, mastitis was most commonly caused by Staphylococcus aureus (24%), Streptococcus spp. (22%), Streptococcus agalactiae (12%) and coagulase-negative staphylococci (11%). In 2014, the most common pathogens were Streptococcus spp. (25%), Staphylococcus aureus (18%) and coagulase-negative staphylococci (10%); in 2015, 2016, 2017, 2018 and 2019, Streptococcus spp. (from 39-49%) were the most frequent strains isolated from the quarter milk samples. Other pathogens were isolated occasionally (below 15% in all years). In conclusion, the role of environmental bacteria has been gradually increasing in the Warmia Province. The importance of infectious pathogens has been decreasing, indicating the efficacy of the applied preventive programmes and a need for the development of new programmes targeting environmental pathogens.

链球菌是波兰东北部奶牛乳腺炎新的优势病因:2013-2019年结果分析

我们研究的目的是评估波兰东北部奶牛乳腺炎的选定细菌和真菌病原体的患病率。我们的研究于2013年至2019年在1665份临床和亚临床感染的四分之一牛奶样本中进行(2013年，n = 368;2014, n = 350;2015, n = 290;2016年，n = 170;2017, n = 173;2018, n = 224;2019年，n = 90)。病原体的分离和鉴定是按照普遍接受的微生物学程序进行的。2013年，引起乳腺炎最常见的是金黄色葡萄球菌(24%)、链球菌(22%)、无乳链球菌(12%)和凝固酶阴性葡萄球菌(11%)。2014年最常见的病原菌为链球菌(25%)、金黄色葡萄球菌(18%)和凝固酶阴性葡萄球菌(10%);2015年、2016年、2017年、2018年和2019年，从四分之一的牛奶样本中分离出的最常见菌株是链球菌(39-49%)。其他病原体偶尔被分离(所有年份低于15%)。综上所述，环境细菌在瓦姆尼亚省的作用逐渐增强。传染性病原体的重要性一直在下降，这表明所实施的预防方案的效力和需要制定针对环境病原体的新方案。

期刊介绍： Irish Veterinary Journal is an open access journal with a vision to make a substantial contribution to the dissemination of evidence-based knowledge that will promote optimal health and welfare of both domestic and wild species of animals. Irish Veterinary Journal has a clinical research focus with an emphasis on the effective management of health in both individual and populations of animals. Published studies will be relevant to both the international veterinary profession and veterinary scientists. Papers relating to veterinary education, veterinary ethics, veterinary public health, or relevant studies in the area of social science (participatory research) are also within the scope of Irish Veterinary Journal.
