猪链球菌、牛链球菌和乳房炎病原体停乳链球菌和尿链球菌是牛扁桃体中最常见的链球菌。猪链球菌在1月龄至1岁小牛的样本中占主导地位，但在1月龄以下小牛中的频率要低得多。乳腺炎病原体链球菌。停乳在小牛中比在老年动物中更常见。肠球菌是相对罕见的，除了在最年轻的年龄组。近三分之一的菌株无法鉴定为已知种。
Streptococcus suis, Streptococcus bovis and the mastitis pathogens Streptococcus dysgalactiae and Streptococcus uberis were the most frequently occurring streptococci in tonsils of cattle. Streptococcus suis dominated in samples from calves between 1 month and 1 year of age, but was much less frequent in calves less than 1 month old. The mastitis pathogen Strep. dysgalactiae was found more often in calves than in older animals. Enterococci were relatively rare, except in the youngest age group. Nearly one third of the strains examined could not be identified to known species.
