Feline lung worm infection is increasingly reported in recent years, and recognized as a cause for respiratory disease in cats. Aelurostrongylus abstrusus is regarded as the most prevalent cause of such cases. Infective L3 larvae carried in gastropods and paratenic hosts infect felines, developing to adult worms that reside in the lungs' parenchyma and may cause verminous pneumonia. The L1 larvae hatch from eggs deposited in the lung, and are released to the environment by either feces or sputum. While the majority of epidemiological information regarding A. abstrusus originates in European countries, recent studies have shown that it is also found around the Mediterranean basin, as far east as Turkey and Cyprus. A local domestic cat from Israel showing signs of respiratory illness was diagnosed with aelurostrongylosis, confirmed by both morphological and molecular tools. Presence in Israel of this nematode was previously reported in 1949, with no further mentions since. ITS-2 sequence of the isolated larvae was highly similar to that of A. abstrusus from domestic cats from Italy. These findings show that distribution of A. abstrusus stretch to the eastern shores of the Mediterranean, and that this nematode should be considered as a cause for respiratory disease in cats in Israel and the surrounding countries.
近年来,猫肺线虫感染的报道日益增多,并被认为是猫呼吸系统疾病的一个病因。隐匿猫圆线虫被视为此类病例的最常见病因。腹足类动物和转续宿主携带的感染性L3幼虫感染猫,发育为成虫后寄生于肺实质,可能导致蠕虫性肺炎。L1幼虫从沉积在肺部的虫卵中孵化出来,通过粪便或痰液释放到环境中。虽然关于隐匿猫圆线虫的大多数流行病学信息源自欧洲国家,但最近的研究表明,在地中海盆地周边地区也能发现它,最东边远至土耳其和塞浦路斯。一只出现呼吸道疾病症状的以色列本地家猫被诊断为感染了猫圆线虫病,这通过形态学和分子工具得以证实。此前在1949年曾报道过以色列存在这种线虫,但此后再无相关提及。分离出的幼虫的ITS-2序列与来自意大利家猫的隐匿猫圆线虫的序列高度相似。这些发现表明,隐匿猫圆线虫的分布延伸至地中海东岸,并且这种线虫应被视为以色列及周边国家猫呼吸系统疾病的一个病因。
