Prevalence and diversity of Trichomonas gallinae in meat pigeons (Columba livia) in Guangdong Province, People’s Republic of China

Genotypic diversity and epidemiology of Trichomonas gallinae in Columbidae: Insights from a comprehensive analysis

“…Subsequently, as management practices and rearing conditions improved and the environment changed, the positivity rate of T. gallinae decreased. In Guangdong Province, China, T. gallinae infection rates in meat pigeons have been reported since 2009, with a positivity rate of 33.9% in 2009 ( Qiu et al, 2012 ), 36.7% in 2017 ( Qiu et al, 2017 ), and 38.9% in 2020, and a recent publication in 2022 reported a decrease in the T. gallinae positivity rate to 26.6% ( Cai et al, 2022 ). These findings were consistent with the overall global analysis results.…”

Drug resistance patterns and genotype associations of Trichomonas gallinae in meat pigeons (Columba livia): insights from Guangdong Province, China

“…The extracted DNA was subsequently stored at a temperature of −40°C. Thereafter, the rDNA sequences (18S rRNA/ITS1-5.8S rRNA-ITS2) were amplified from the genomic DNA of each T. gallinae isolate using the polymerase chain reaction (PCR) with the primers, TgaTrend-F (5′-ACTGCCGGAGAAGGCGCCTGAG-3′) and TgaTrend-R (5′-TAAGACGTTGGGCTGTTCCCTT-3′), which described in our previous work ( 16 ). The primers were synthesized by Guangzhou IGE Biotechnology Co., Ltd.…”

“…Feng et al ( 15 ) surveyed pigeon farms in Beijing and observed that 28.3% of the pigeons were infected with T. gallinae . In our previous study, we detected an overall 26.6% (169/636) prevalence of T. gallinae infection in southern China ( 16 ).…”

Prevalence and molecular characterization of Trichomonas gallinae from pigeons in Anhui, China

“…In China, being one of the four major poultry products, pigeons are a key component of Chinese cuisine (Ji et al 2020). The T. gallinae infection in pigeons is increasingly documented in different provinces, including Sichuan (Huang et al 2008), Shandong (Jiang et al 2016), Guangdong (Cai et al 2022), and Beijing (Feng et al 2018). Despite the substantial growth of the pigeon industry in recent years and the increased focus on pigeon production, there is a few of reports on T. gallinae in China.…”
