Corvidae is a cosmopolitan family of oscine birds including crows, rooks, magpies, jays, chough, and ravens. These birds are migratory species, especially in the shortage of foods, so they can act like vectors for a wide range of microorganisms. They live generally in temperate climates and in a very close contact with human residential areas as well as poultry farms. There is no available information in the literature concerning the parasitic infections of these three species of corvidae in Mazandaran Province, northern Iran, so this study was conducted to clarify this.
As there are three species of corvid birds in Mazandaran Province, 106 birds including 79 magpies, 11 rooks, and 16 carrion crows were examined between winter 2007 and spring 2008 at post mortem for gastrointestinal helminths. The helminths were drawn and identified morphologically in the Laboratory of Parasitology, Islamic Azad University, Science and Research Branch, Tehran and also partly in the School of Public Health, Tehran University of Medical Sciences, based on the reference books and identification keys like Soulsby, Khalil et al. and Anderson et al.
Four species of nematodes, 2 species of cestodes, 1 species of trematodes and 1 species of acanthocephalans were identified in these three corvid species.
Five species of the helminths are identified for the first time in Iran, and the acanthocephalan species is new host record for rooks. It is clear that these corvid birds have diverse range of helminths and can act as carriers for infecting the domestic fowls.
鸦科是鸣禽中的一个世界性科，包括乌鸦、白嘴鸦、喜鹊、松鸦、红嘴山鸦和渡鸦。这些鸟类是迁徙物种，尤其是在食物短缺时，因此它们可以充当多种微生物的传播媒介。它们一般生活在温带气候地区，与人类居住区以及家禽养殖场密切接触。关于伊朗北部马赞德兰省这三种鸦科鸟类的寄生虫感染情况，文献中尚无可用信息，因此开展本研究以阐明这一情况。
由于马赞德兰省有三种鸦科鸟类，于2007年冬季至2008年春季对106只鸟进行了尸检，检查其胃肠道蠕虫，其中包括79只喜鹊、11只白嘴鸦和16只食腐鸦。在德黑兰伊斯兰阿扎德大学科学与研究分校的寄生虫学实验室，并部分在德黑兰医科大学公共卫生学院，依据《索尔兹比》《哈利勒等人》以及《安德森等人》等参考书和鉴定手册，对蠕虫进行形态绘制和鉴定。
在这三种鸦科鸟类中鉴定出了4种线虫、2种绦虫、1种吸虫和1种棘头虫。
5种蠕虫在伊朗首次被鉴定出来，该棘头虫物种是白嘴鸦的新宿主记录。显然，这些鸦科鸟类体内有多种蠕虫，可作为感染家禽的携带者。
