RESUMO
Toxoplasma gondii is a worldwide distribution of Apicom-plexans,which are widely parasitic in human and warm-blooded animals.Due to the factors such as host and geographical distribution,the population structure has rich genetic diversity.At present,the study of the genotype of Toxoplasma gondii and summary papers are relatively few.This paper reviews the biological information that has been reported in the world regarding the toxoplasmosis of birds such as domesticated chickens,ornamental birds,pet birds and wild rare birds,and to provide basis for further research on biological information such as epidemiology of bird toxoplasmosis and population structure of insects.
RESUMO
Balantidium coli infects humans, primates and pigs, causing serious diarrhea and dysentery. Little information on the prevalence of B. coli in primates is available in China. This investigation was conducted to determine the prevalence of B. coli infection in bred rhesus monkeys in Guangxi Zhuang Nationality Autonomous Region [GZNAR] southern China. A total of 120 fecal samples were collected from rhesus monkeys bred in cages in GZNAR and B. coli cysts and/or trophozoites were examined microscopically after sedimentation with water in May 2013. 77 [64.2%] samples were tested positive. The prevalence was 65% [39/60] and 63.3% [38/60] in female and male monkeys, respectively. 80% [48/60] cages in this nonhuman primate center were positive for B. coli. The present survey revealed high circulation of B. coli in bred rhesus monkeys in GZNAR, which poses potential threats to animal and human health
