Salmonella and Yersinia are important enteropathogens in poultry and can affect birds of all ages, including embryos. These food-borne zoonotic enteropathogens are of great economic and medical concern worldwide and are intensely studied in poultry. Information regarding the prevalence of these bacteria in wild birds is scarce and biased toward avian species ecologically linked to humans, which have often been incriminated as both reservoirs and disseminators of these enteropathogens. The prevalence of Salmonella and Yersinia recovered from both the feces and eggs in a population of female pied flycatchers (Ficedula hypoleuca) breeding in nest-boxes in central Spain was evaluated. Salmonella arizonae was recovered from the feces of one female but was not recovered from eggs. Yersinia was not detected in either the feces or eggs. These results may suggest that Salmonella and Yersinia may be uncommon in this population studied and may indicate that these birds are unlikely reservoirs of Salmonella and Yersinia.
沙门氏菌和耶尔森氏菌是家禽体内重要的肠道病原体，可感染包括胚胎在内的所有年龄段禽类。这些食源性人畜共患肠道病原体在全球范围内引发了重大的经济和医学问题，在家禽领域受到广泛研究。关于这些细菌在野生鸟类中的流行情况的信息匮乏，且偏向于与人类有生态联系的鸟类物种，这些鸟类常被认定为这些肠道病原体的宿主和传播者。对西班牙中部在巢箱中繁殖的雌性斑姬鹟（Ficedula hypoleuca）群体的粪便和鸟蛋中沙门氏菌和耶尔森氏菌的检出率进行了评估。从一只雌性斑姬鹟的粪便中分离出了亚利桑那沙门氏菌，但在鸟蛋中未检出。在粪便和鸟蛋中均未检测到耶尔森氏菌。这些结果可能表明，在所研究的这一群体中，沙门氏菌和耶尔森氏菌可能并不常见，也可能意味着这些鸟类不太可能是沙门氏菌和耶尔森氏菌的宿主。
