【摘要】 为了解2019年鸡传染性鼻炎在国内的流行状况,对来自全国多个地区的20组临床疑似病例进行副鸡禽杆菌的分离培养和血清型鉴定。结果显示:20组病例中有15组病例分离到副鸡禽杆菌,其中10组为A型、5组为C型。表明2019年流行的副鸡禽杆菌以A、C型为主,前几年流行较为广泛的B型副鸡禽杆菌在2019年较为少见,提示我国部分地区鸡传染性鼻炎流行菌株的血清型在2019年发生了明显的变化。更多还原

【Abstract】 In order to understand the epidemiology of infectious coryza in 2019, Avibacterium paragallinarum isolates were identified and serotyped from 20 clinically suspected infectious coryza cases originated from different regions of China. The results showed that Avibacterium paragallinarum isolates were obtained from 15 out of 20 cases. Within the15 cases, 10 cases were serovar A and 5 were serovar C. These data indicated that the major serovars of Avibacterium paragallinarum in 2019 were serovar A and C, while serovar B prevalent in previous years became relatively rare in this year. Overall, it′s suggested that the prevalent serovars of Avibacterium paragallinarum strains causing infectious coryza exhibited some differences in 2019.更多还原
