Bertiella sp. is a typical parasite in non-human primates and only a few cases of bertiellosis have been reported in humans. We present a new case study of bertiellosis in a 42-year-old woman caretaker of howler monkeys in a wild rehabilitation center in Argentina. Bertiella sp. infection was also diagnosed in the monkeys. Proglottids and feces were collected from the caretaker and monkeys; the samples were submitted for parasitological examination by morphological characterization and molecular identification using both nuclear (18S and ITS1-5.8-ITS2 rDNA) and mitochondrial (cox1) markers. Morphological and molecular data were consistent and allowed the classification of the specimen to the genus level. The analyses also showed the presence of cysts of Giardia lamblia and oocysts of Cryptosporidium spp. in howler monkeys, and cysts of Blastocystis sp. in both the caretaker and monkeys. This study recorded the fourth case of bertiellosis in a human host from Argentina and the eighth case in South America. Moreover, this is the first study that compares the morphological and molecular features of Bertiella sp. found in both a human and monkeys from the same geographical region. These results suggest that the cohabitation between humans and monkeys increases the opportunities of infection by Bertiella sp. and other potential zoonotic parasites.
伯特氏菌属是一种典型的非人类灵长类寄生虫，仅有少数几例伯特氏菌病在人类中报告。我们报告了在阿根廷一个野生康复中心的一名 42 岁的吼猴饲养员中伯特氏菌病的新病例研究。猴子中也诊断出了伯特氏菌属感染。从饲养员和猴子中收集了绦虫节片和粪便；通过形态特征和分子鉴定（使用核（18S 和 ITS1-5.8-ITS2 rDNA）和线粒体（cox1）标记）对这些样本进行了寄生虫学检查。形态学和分子数据是一致的，并允许将标本分类到属水平。分析还显示在吼猴中存在蓝氏贾第鞭毛虫包囊和隐孢子虫属卵囊，以及在饲养员和猴子中存在芽囊原虫属包囊。这项研究记录了来自阿根廷的第四例人类宿主伯特氏菌病病例，也是南美洲的第八例。此外，这是首次比较同一地理区域的人类和猴子中发现的伯特氏菌属的形态和分子特征的研究。这些结果表明，人类和猴子的共同生活增加了感染伯特氏菌属和其他潜在人畜共患寄生虫的机会。
