Abstract:
When the zoonotic parasite of rodents that can cause human neuroangiostrongyliasis, i.e., Angiostrongylus cantonensis, is found in its natural definitive hosts, it is usually reported in isolation, as if the rat lungworm were the only component of its parasite community. In this study, we report the coinfections found in rats naturally infected by A. cantonensis in urban populations of Rattus norvegicus and Rattus rattus in Valencia, Spain. In addition to the rat lungworms, which were found in 14 of the 125 rats studied (a prevalence of 11.20%), 18 other parasite species (intestinal and tissular protists, microsporidia and helminths) were found, some of them with high burdens. Fourteen of these nineteen species found are potential zoonotic parasites, namely Blastocystis, Giardia duodenalis, Cryptosporidium spp., Enterocytozoon bieneusi, Encephalitozoon hellem, Toxoplasma gondii, Brachylaima spp., Hydatigera taeniaeformis s.l. larvae, Hymenolepis nana, Hymenolepis diminuta, Angiostrongylus cantonensis, Calodium hepaticum, Gongylonema neoplasticum and Moniliformis moniliformis. The total predominance of coinfected rats as well as their high parasite loads seem to indicate a trend towards parasite tolerance.
摘要:
当啮齿动物的人畜共患寄生虫,可以引起人类神经管圆线虫病,即,广州管圆线虫,在它的自然确定宿主中发现,通常是孤立报道的,好像老鼠肺虫是其寄生虫群落的唯一组成部分。在这项研究中,我们报告了在巴伦西亚的城市人口中被自然感染的鼠中发现的共感染。西班牙。除了鼠肺虫,在研究的125只大鼠中有14只(患病率为11.20%),其他18种寄生虫(肠道和组织原生生物,发现了微孢子虫和蠕虫),他们中的一些人负担很高。发现的19种物种中有14种是潜在的人畜共患寄生虫,即胚泡,十二指肠贾第虫,隐孢子虫。,肠孢子虫Bieneusi,头颅虫直升机,弓形虫,Brachylaimaspp.,双黄鱼幼虫,处女膜外膜外膜,处女膜减少,广州管圆线虫,肝肠,刚毛和念珠。共感染的大鼠的总体优势以及它们的高寄生虫负荷似乎表明了寄生虫耐受性的趋势。
