“…To our knowledge, there was only one report regarding T. gondii infection in geese in Guangdong, China [10], and the seroprevalence (4.7%) in Shenyang in this study was lower than 15.0% in Gungdong. Seroprevalence of T. gondii infection from 3 poultry abattoirs ranged from 6.7% to 8.3% (Table 2).…”

BackgroundIn recent years, investigations of Toxoplasma gondii infection in poultry (chickens, ducks, and geese) have been reported worldwide, including China. However, little is known about the prevalence of T. gondii infection in poultry in northeastern China. Therefore, the present study was performed to determine the prevalence of T. gondii infection in slaughtered chickens, ducks, and geese in Shenyang, northeastern China.MethodsIn the present study, the seroprevalence of T. gondii in 502 adult chickens, 268 adult ducks, and 128 adult geese was surveyed using the modified agglutination test (MAT).ResultsThe seroprevalences of T. gondii were 5.8%, 7.8%, and 4.7% in chickens, ducks, and geese, respectively. Prevalence was higher in free-range groups (11.2%, 12.3%, and 8.9%) than caged groups (4.7%, 7.5%, and 6.0%), and there was a statistically significant difference only between free-range chickens and caged chickens, but no significant difference was found between free-range ducks, geese and caged ducks, geese.ConclusionsThe present study shows the prescence of T. gondii infection in slaughtered chickens, ducks, and geese in Shenyang, northeastern China, which suggests that consumption of poultry meat in Shenyang may pose a potential threat to human health and should be given attention.

“…The modified agglutination test (MAT) has been evaluated extensively in experimentally and naturally infected birds, and is sensitive and specific for assay of T. gondii antibodies [1,10,13,14], compared to other serologic methods. However, the test needs to be validated by bioassays of viable T. gondii from meat consumed by humans in China.…”

“…In this study, we chose MAT because it is sensitive and specific for detecting T. gondii antibodies in bird species [2,8,13-15], compared to other serologic methods. Moreover, geographical conditions, feeding and living styles, and number of cats and rodents may contribute to the differences in T. gondii seropositivity in birds.…”

“…In brief, sera were added to the “U” bottom of 96 well microtiter plates, and diluted two-fold starting from 1:5 to 1:160. Bird sera with MAT titers of 1:5 or higher were considered positive for T. gondii antibodies based on previous studies [2,8,13-15], those sera with doubtful reactions were re-tested, and positive and negative controls were included in each test.…”

BackgroundToxoplasma gondii infection is a global concern, affecting a wide range of warm-blooded animals and humans worldwide, including poultry. Domestic and companion birds are considered to play an important role in the transmission of T. gondii to humans and other animals. However, little information on T. gondii infection in domestic birds in Lanzhou, northwest China was available. Therefore, this study was performed to determine the seroprevalence of T. gondii infection in domestic birds in Lanzhou, northwest China.MethodsIn the present study, the seroprevalence of T. gondii antibodies in 413 (305 caged and 108 free-range) adult chickens, 334 (111 caged and 223 free-range) adult ducks and 312 adult pigeons in Lanzhou, northwest China, were examined using the modified agglutination test (MAT).Results30 (7.26%) chickens, 38 (11.38%) ducks and 37 (11.86%) pigeons were found to be positive for T. gondii antibodies at the cut-off of 1:5. The prevalences in caged and free-range chickens were 6.23% and 10.19% respectively, however, statistical analysis showed that the difference was not significant (P > 0.05). The seroprevalences in caged and free-range ducks were 6.31% and 13.90% respectively, but the difference was not statistically significant (P > 0.05).ConclusionsThe results of the present survey indicated the presence of T. gondii infection in adult chickens, ducks and pigeons sold for meat in poultry markets in Lanzhou, northwest China, which poses a potential risk for T. gondii infection in humans and other animals in this region. This is the first seroprevalence study of T. gondii infection in domestic birds in this region.

“…Goose meat is an important foodstuff worldwide, and humans can acquire infections with T. gondii by ingesting undercooked goose meat containing tissue cysts. Surveys of seroprevalence of T. gondii infection in geese have been reported throughout the world [6][7][8], and there have also been surveys of T. gondii infection in geese in several provinces of China in recent years [9,10]. The People's Republic of China (PRC) is one of the largest producers of geese in the world, and Hainan province, tropical China is one of the major geese producers in the PRC.…”

Background: Little information is available about the seroprevalence of Toxoplasma gondii infection in geese (Anser domestica) in China. In the present investigation, the seroprevalence, risk factors and genotyping of T. gondii in geese were investigated in Hainan province, tropical China. Findings: A total of 600 serum samples and 150 brain tissue samples were collected from six administrative regions in tropical China, and assayed for T. gondii antibodies by Indirect Haemagglutination (IHA) test. Genomic DNA was extracted from the 30 brain tissues of seropositive geese and T. gondii B1 gene was amplified using a semi-nested PCR. DNA samples giving positive B1 amplification were then genetically characterized using multi-locus PCR-RFLP. Overall, 17% (95% CI: 14-20) of the animals were positive for T. gondii antibodies. Presence of cats in the household (odds ratio, OR 3), hygiene (OR 2.3) and presence of stray cat around the house (OR 2.3) were considered as main risk factors associated with T. gondii infection. Of 30 DNA samples, three were positive for the T. gondii B1 gene, two showed complete genotyping results. Only one genotype (type II) was identified. Conclusions:The results of the present survey indicated the presence of T. gondii infection in geese in tropical China. Therefore, it is imperative that improved integrated measures be carried out to prevent and control T. gondii infection in geese in this province. This is the first report documenting the occurrence of T. gondii genotype in geese in China.
