The prevalence of S. bovis in the intestinal tract of healthy racing pigeons was determined. Crop and cloaca swab samples obtained from 810 pigeons from 14 different lofts and from 122 pigeons that were presented for routine health control were examined for the presence of S. bovis. Pooled faecal samples were also obtained from pigeons in 82 different pigeon lofts. S. bovis was isolated from crop or cloaca samples of approximately 40% of pigeons of all ages by direct culture and from 80% of the pooled faecal samples by enrichment culture. In a longitudinal study, crop and cloaca samples were collected every 3 months from pigeons in seven different pigeon lofts. The prevalence of S. bovis in these pigeons ranged from 0 to 100%. The carriage rate was not related to the season or to the age of the pigeons. The prevalence of S. bovis in organ lesions of pigeons examined at necropsy was investigated over a 35-month period. S. bovis was isolated from 10% of the birds examined. The incidence of S. bovis septicaemia was significantly higher in January to August than in September to December. It was concluded that S. bovis is an opportunistic pathogenic agent in pigeons.
测定了健康赛鸽肠道中牛链球菌的流行情况。从14个不同鸽舍的810只鸽子以及前来进行常规健康检查的122只鸽子中采集嗉囊和泄殖腔拭子样本，检测其中是否存在牛链球菌。还从82个不同鸽舍的鸽子中获取了混合粪便样本。通过直接培养，约40%各年龄段鸽子的嗉囊或泄殖腔样本中分离出牛链球菌；通过富集培养，80%的混合粪便样本中分离出牛链球菌。在一项纵向研究中，每3个月从7个不同鸽舍的鸽子中采集嗉囊和泄殖腔样本。这些鸽子中牛链球菌的流行率在0%至100%之间。携带率与季节或鸽子年龄无关。在35个月的时间里，对尸检时检查的鸽子器官病变中牛链球菌的流行情况进行了调查。在所检查的鸟类中，10%分离出牛链球菌。1月至8月牛链球菌败血症的发病率明显高于9月至12月。得出的结论是，牛链球菌是鸽子中的一种机会性致病病原体。
