摘要: 为调查引起粤东地区鸡传染性病毒性腺胃炎的主要病因和感染情况,对粤东地区 病鸡样品共490份进行剖检,并按10份合1进行相关病毒检测。结果表明,引起该地区鸡传染 性病毒性腺胃炎的疾病主要为免疫抑制性疾病,感染率最高的是鸡传染性贫血病毒,检出率 高达53.1%(26/49);马立克病病毒检出率位居第二,为28.6%(14/49)。另外,网状内皮增生症 病毒和圆圈病毒3型的检出率均为14.3%(7/49),传染性支气管炎病毒等四种病原未检出。研 究表明引起免疫抑制性疾病的病毒可能是粤东地区鸡传染性病毒性腺胃炎的主要病原。另 外,发病鸡主要集中在28??92日龄的中鸡,夏季和秋季多发,春季少发。本研究通过对粤东地 区鸡传染性病毒性腺胃炎的主要病因和感染情况进行系统研究,为粤东地区鸡传染性病毒性 腺胃炎的预防和控制提供指导。

Abstract: In order to investigate the main causes and infection of chicken Transmissible viral proventriculitis (TVP)in the eastern Guangdong,490 samples of diseased chicken were dissected and tested for relevant viruses at ten in one. Our results showed that the disease causing chicken infectious virus gonaditis in this area was mainly immunosuppressive disease. The major pathogen included chicken infectious anemia virus with a highest infection rate of 53.1%(26/49),and Marek's disease virus ranked second with 28.6%(14/49). In addition,the detection rate of Reticuloendotheliosis virus and Circovirus type 3 virus was 14.3%(7/49),but other viruses (e.g.,avian infectious bronchitis virus) were not detected. Our research indicated that the virus causing immunosuppressive diseases may be the main factor of TVP in the eastern Guangdong. The susceptible infection age of chicken TVP was from 28 to 92 days,the infection period was common in summer,autumn,but rare in spring. This is a systematic research on the main cause and infection situation of chicken TVP in the eastern Guangdong,and it will provide guidance for avain TVP prevention and control in this area.
