Prevalence of Toxoplasma gondii infection in chickens in China during 1993–2021: a systematic review and meta-analysis

Toxoplasma gondii is an important intracellular parasitic protozoan with a variety of hosts, including chickens, which poses a potential threat to public health. However, little is known regarding overall T. gondii infection in chickens in China. Herein, the prevalence and risk factors associated wi...

Description
Summary:Toxoplasma gondii is an important intracellular parasitic protozoan with a variety of hosts, including chickens, which poses a potential threat to public health. However, little is known regarding overall T. gondii infection in chickens in China. Herein, the prevalence and risk factors associated with T. gondii infection in chickens in China were investigated using a meta-analysis. Forty studies regarding the prevalence of T. gondii in chickens in China from 1993 to 2021 were identified using five databases (PubMed, Science Direct, CNKI, Wang Fang, and VIP). Quantitative and potential sources were analyzed through subgroup analysis and meta-regression in R v3.5.2. The overall prevalence of T. gondii in chickens in China was 13.4% (95% confidence interval (CI): 10.9–16.0) . In the region subgroup, the lowest prevalence was presented in Northwestern China (6.0%, 95% CI: 3.2–9.5; P
