A parasitological survey was conducted at some zoos in the states of São Paulo and Paraná, Brazil, from 2009 to 2011. Several groups of birds were surveyed for fecal samples, but the most important was Psittacidae. Among the parasites, Eimeria (coccidian) and Capillaria, Ascaridia and Heterakis (nematodes) were observed in almost one third of the samples. Presence of a rich parasite fauna associated with captive birds seems to be an effect of captivity, since data on free-ranging birds indicate few or virtually no parasites at all. The discovery of new coccidian species during this survey reveals the need of more research on the subject as even well-known bird species have unknown parasites, but caution must be exercised in order to avoid descriptions of pseudoparasites.
2009年至2011年期间,在巴西圣保罗州和巴拉那州的一些动物园进行了一项寄生虫学调查。对几组鸟类的粪便样本进行了检测,但最重要的是鹦鹉科鸟类。在几乎三分之一的样本中发现了艾美球虫(球虫类)、毛细线虫、蛔虫和异刺线虫(线虫类)等寄生虫。圈养鸟类身上存在丰富的寄生虫群落似乎是圈养的结果,因为有关自由放养鸟类的数据表明其体内几乎没有寄生虫。此次调查中发现新的球虫种类,这表明需要对该主题进行更多研究, 因为即使是知名鸟类也存在未知的寄生虫,但必须谨慎行事,以免将伪寄生虫误判为新物种。
