There is limited available information concerning the prevalence of Toxoplasma gondii in noncaptive monkeys. Also, New World monkeys (NWM) are highly susceptible to toxoplasmosis, which is a conservation concern. This study aimed to investigate apicomplexan parasites in common marmosets (Callithrix jacchus) collected for yellow fever and rabies surveillance program in Northeastern region of Brazil. Heart fragments of 39 free-ranging common marmosets were analyzed for the presence of the 18S rDNA gene of apicomplexan parasites by nested PCR. Positive samples were sequenced. T. gondii DNA was detected in 17.9% (7/39) of the analyzed animals. This study is the first report on T. gondii in Callithrix jacchus in Brazil. These findings should be an alert for wildlife conservation institutions, as high susceptibility and mortality were reported for captive NWM.
关于非圈养猴子中弓形虫的流行情况，现有信息有限。此外，新大陆猴对弓形虫病高度易感，这是一个与保护相关的问题。本研究旨在调查在巴西东北部为黄热病和狂犬病监测项目收集的普通狨猴（Callithrix jacchus）中的顶复门寄生虫。通过巢式PCR分析了39只自由放养的普通狨猴的心脏片段，以检测顶复门寄生虫18S rDNA基因的存在情况。对阳性样本进行了测序。在17.9%（7/39）的分析动物中检测到了弓形虫DNA。本研究是巴西关于Callithrix jacchus中弓形虫的首次报告。这些发现应引起野生动物保护机构的警觉，因为据报道圈养的新大陆猴易感性高且死亡率高。
