Species of Babesia are intraerythrocytic protozoal parasites of many species of mammalians in all parts of the world where the tick-vectors are found. Babesiosis or piroplasmosis causes considerable damage to the livestock and other animals. Human babesiosis has been documented in many countries. Consequently, babesiosis is a zoonotic disease of medical, veterinary and economic importance. In this study, a total of 310 rodents of different species were trapped from different areas in Riyadh Region, Saudi Arabia. These rodents were; Rattus rattus (142), R. norvegicus (24), Mus musculus (8), Meriones crassus (56), Jaculus jaculus (16), Gerbillus cheesmani (50) and Acomys c. dimidiatus (14). Natural Babesia infection was parasitologically detected in 95 of them (30.65%). The highest infection rate was among R. rattus (34.5%). The lowest rate was among G. cheesmani (20%). None of the M. musculus was infected. Since most of these rodents are commensal ie living in close contact with man, a general discussion on the pathogenesis, immunity and diagnosis was given.
巴贝斯虫属的物种是红细胞内的原生动物寄生虫，存在于世界各地发现蜱传播媒介的许多哺乳动物物种中。巴贝斯虫病或梨形虫病会对家畜和其他动物造成相当大的损害。许多国家都记录了人类巴贝斯虫病。因此，巴贝斯虫病是一种具有医学、兽医和经济重要性的人畜共患病。在本研究中，从沙特阿拉伯利雅得地区的不同区域捕获了总共310只不同物种的啮齿动物。这些啮齿动物包括：黑家鼠（142只）、褐家鼠（24只）、小家鼠（8只）、肥尾心颅跳鼠（56只）、埃及沙鼠（16只）、谢氏沙鼠（50只）和荒漠刺毛鼠（14只）。通过寄生虫学检测发现其中95只（30.65%）感染了自然感染的巴贝斯虫。感染率最高的是黑家鼠（34.5%）。最低的是谢氏沙鼠（20%）。小家鼠均未感染。由于这些啮齿动物大多与人类共生，即与人类密切接触，因此对其发病机制、免疫和诊断进行了一般性讨论。
