is diffused worldwide, and subsp. is spread worldwide with many serovars associated with the infection of domestic bovines. The most spread are . Dublin, . Typhimurium and . Infantis. Napoli is, however very rarely reported in domestic ruminants. Here, we report an outbreak of . Napoli on a dairy cow farm in Northern Italy (Piacenza). A total of 18 . Napoli isolates were recovered from aborted fetuses, feces, tissues and environmental samples. Whole genome sequencing suggested that all isolates belonged to the same cluster. After the application of stringent biocontainment and biosecurity measures, no further cases were reported. However, four months after the first case, the serovar was still isolated in environmental samples, underlying the importance of adopting the correct biosecurity and biocontainment measures in order to prevent the circulation and transmission of within the farm.
广泛传播于全球，亚种在全球范围内传播，有许多血清型与家养牛的感染有关。传播最广的是都柏林血清型、鼠伤寒血清型和婴儿血清型。然而，那不勒斯血清型在家养反刍动物中很少被报道。在此，我们报告意大利北部（皮亚琴察）一个奶牛场爆发了那不勒斯血清型感染。从流产胎儿、粪便、组织和环境样本中总共分离出18株那不勒斯血清型菌株。全基因组测序表明所有分离株属于同一簇。在采取严格的生物遏制和生物安全措施后，未再报告病例。然而，首例病例出现四个月后，该血清型仍在环境样本中被分离出来，这突出了采取正确的生物安全和生物遏制措施以防止该血清型在农场内传播和扩散的重要性。
