On the occasion of a large exhibition of pure-breed fancy pigeons 398 animals from 49 different dovecotes were examined for Salmonella shedding. Faecal samples were taken after caging of the birds for the exhibition and after 3 days, before the end of the exhibition. Salmonella were detected in faeces of 28 out of 398 pigeons (7.04%). 10 birds were Salmonella positive only after caging for the exhibition, 10 other animals only before the end of the exhibition, and 8 pigeons at both occasions. The Salmonella positive birds originated from 15 different dovecotes, i.e. in ca. 30% of the dovecotes at the exhibition at least 1 Salmonella positive pigeon was identified. The share of positive birds in these dovecotes varied between 5% and 83%. All Salmonella isolates belonged to the serovar Typhimurium variant copenhagen and were of phage type DT 2. The results of this study do not provide complete evidence on the spreading of Salmonella organisms from birds infected at time of caging to other pigeons during the exhibition, however, such transmission cannot be excluded. In only 18 dovecotes pigeons were immunised against Salmonella Typhimurium. However, in these dovecotes all breeder birds but only 13% of the young pigeons had been immunised. Among the vaccinated breeder pigeons the number of Salmonella positive birds was considerably lower (not significant) than among the non-vaccinated breeders. There is epidemiological evidence that vaccination of pigeons has a considerable protective effect against Salmonella exposure. However, in order to effectively reduce Salmonella findings in pure-breed fancy pigeons it is recommended to provide vaccination to pigeons in a greater number of dovecotes and to include the progeny, too.
在一次大型纯种观赏鸽展览会上，对来自49个不同鸽舍的398只鸽子进行了沙门氏菌排泄检测。在鸽子为展览关进笼子后以及展览结束前3天采集粪便样本。398只鸽子中有28只（7.04%）粪便中检测出沙门氏菌。10只鸽子仅在关进笼子准备展览后沙门氏菌呈阳性，另外10只仅在展览结束前呈阳性，8只鸽子在这两个阶段均呈阳性。沙门氏菌呈阳性的鸽子来自15个不同的鸽舍，即在展览会上约30%的鸽舍中至少鉴定出1只沙门氏菌呈阳性的鸽子。这些鸽舍中阳性鸽子的比例在5%至83%之间。所有沙门氏菌分离株均属于鼠伤寒血清型哥本哈根变种，噬菌体类型为DT 2。本研究结果并未提供关于在展览期间沙门氏菌从关进笼子时受感染的鸽子传播到其他鸽子的确凿证据，然而，这种传播不能排除。只有18个鸽舍的鸽子接种了鼠伤寒沙门氏菌疫苗。然而，在这些鸽舍中，所有种鸽都接种了疫苗，但幼鸽中只有13%接种了疫苗。在接种疫苗的种鸽中，沙门氏菌呈阳性的鸽子数量比未接种疫苗的种鸽显著少（无统计学意义）。有流行病学证据表明，给鸽子接种疫苗对预防沙门氏菌感染有相当大的保护作用。然而，为了有效减少纯种观赏鸽中沙门氏菌的检出率，建议在更多鸽舍给鸽子接种疫苗，并将幼鸽也纳入接种范围。
