Abstract

The prokaryotic microorganism Mycoplasma gallisepticum (MG) belongs to the phylum Firmicutes, the order Mycoplasmatales, the family Mycoplasmataceae, and the genus Mycoplasma. MG parasitizes the respiratory tract of various poultry species, causing a range of symptoms from indistinct features to tracheitis and air sacculitis. Common signs include respiratory tract infection indicators such as coughing, asthma, a runny nose and rales. Both domestic and international reports underscore MG's transmission and infection capacity, signifying its global importance as a source of poultry infection. Further research is imperative to grasp its impact on both farmed and wild animals. This article comprehensively reviews current research progress on MG, encompassing its biological characteristics, infection traits, pathogenic mechanisms, epidemiology, detection methods, treatment, and control measures. It aims to serve as a reference for comprehensive prevention and control strategies against MG in the future.

Key words: Mycoplasma galliscepticum, infection characteristics, epidemiological characteristics, detection methods, treatment, vaccine.
