Advances in Research on Pigeon Circovirus

Abstract

鸽圆环病毒(Pigeon circovirus, PiCV)是一种免疫抑制性病原，可在增殖的细胞和免疫系统细胞中加速复制，导致淋巴细胞比率偏低、免疫力下降及鸽免疫系统损伤，可进而出现其它病原的继发感染。目前该病已成为困扰种鸽、赛鸽等养鸽业重要疾病之一，因此，本文通过对鸽圆环病毒基因组结构、致病机理、临床症状、诊断方法以及防控等进行概述，以便对该病毒深入了解，为养鸽业提供圆环病毒防控参考。 PiCV (Pigeon circovirus) is an immunosuppressive pathogen, which can accelerate replication in proliferating cells and immune system cells, resulting in low lymphocyte ratio, decreased immunity and injury of pigeon immune system, which can then lead to secondary infection of other pathogens. At present, the disease has become one of the most important diseases in pigeon breeding, such as pigeon breeding and pigeon racing. Therefore, this paper summarizes the genome structure, pathogenic mechanism, clinical symptoms, diagnostic methods and prevention and control of pigeon ring virus, so as to understand the virus deeply and provide reference for pigeon industry to prevent and control circovirus.
