Mammomonogamus laryngeus is a nematode parasite that is usually found in the larynx of mammals in the tropics, especially in cattle, sheep and cats.
The prevalence of M. laryngeus was determined in cattle brought to an abattoir as an indicator of its prevalence in the general population. Materials and methods. The present study was undertaken in the municipality of La Tebaida, Quindio, Colombia, to determine the presence of M. laryngeus infection in cattle brought to a local abattoir between December and February 2009. The tracheae and lungs of 500 slaughtered cattle were examined.
Parasite prevalence was 14.8% (n=74). The majority of worms were located on aryteno-epiglottic folds, but never in the tracheae or bronchi. The infection rate was highest (47%) in 2 to 2.5 year old animals. In infected animals, an average of 6.4 parasite pairs was found, with higher numbers in older animals. The prevalence of infection in cattle was greater than seen in the provinces of Valle del Cauca (10.0%), Quindío(3,0%) pr Caquetá (1.2%).
Reports of this parasite in cattle indicate its circulation throughout Colombia and recommend surveillance studies where cattle are raised and prepared for human consumption.
喉兽比翼线虫是一种线虫寄生虫，通常发现于热带地区哺乳动物的喉部，尤其是牛、羊和猫。
测定送往屠宰场的牛中喉兽比翼线虫的流行率，以此作为该寄生虫在一般牛群中流行情况的指标。材料与方法。本研究在哥伦比亚昆迪奥省拉泰巴伊达市开展，旨在确定2009年12月至2月间送往当地屠宰场的牛中喉兽比翼线虫感染情况。对500头屠宰牛的气管和肺进行了检查。
寄生虫流行率为14.8%（n = 74）。大多数虫体位于杓会厌襞，但从未在气管或支气管中发现。2至2.5岁的动物感染率最高（47%）。在感染动物中，平均发现6.4对寄生虫，年龄较大的动物寄生虫数量更多。牛的感染率高于考卡山谷省（10.0%）、昆迪奥省（3.0%）或卡克塔省（1.2%）。
关于这种寄生虫在牛中的报道表明其在哥伦比亚各地传播，并建议在饲养牛并准备供人类食用的地方开展监测研究。
