目标。估计在墨西哥住宅及其周围常见的锥虫种类中克氏锥虫感染的流行率，并按州评估城镇中锥虫的发生频率。材料和方法。1993年1月至1999年12月，流行病学诊断和转诊研究所昆虫学系接收了来自墨西哥14个州的5 399只锥虫，用于克氏锥虫的分类确定和寄生虫学研究。在全球范围内分析了1993年至1999年获得的结果。结果。从与人类住所有关的13种臭虫中，9种自然感染克氏锥虫。感染比例最高的是白斑三角瘤、picurata、长尾红螺旋体和长尾螺旋体。纳亚里特、莫雷洛斯州和米却肯州是感染细菌比例最高的州。其中，T. dimidiata、T. gerstaeckeri、T. longgennis、T. mexicana和T. paliidipennis为国家记录，T. rufotuberculatus为地方记录。结论。这些发现强调了研究Triatominae生物学的重要性和长期监测的必要性，以便获得人类住所内和周围、适应人类住所的Triatominae物种的最新分布记录，以及自然感染克氏锥虫的频率。
Objective. To estimate the prevalence of infection with Trypanosoma cruzi in Triatominae species frequently found in and around Mexican dwellings, and to assess the frequency of Triatominae in towns by state. Material and methods. Between January 1993 and December 1999, 5 399 Triatominae bugs from 14 states of Mexico, were received in the Department of Entomology of the Institute for Epidemiologic Diagnosis and Referral (InDRE), for taxonomic determination and parasitoscopical search of Trypanosoma cruzi. Results obtained between 1993 and 1999 were analyzed globally. Results. From 13 bug species associated with human dwellings, nine were naturally infected with T. cruzi. The highest percentage of infection occurred in Triatoma pallidipennis, T. picurata, Rhodnius prolixus and T. longipennis. Nayarit, Morelos, and Michoacan were the states with the highest percentage of infected bugs. The species T. dimidiata, T. gerstaeckeri, T. longgennis, T. mexicana and T. paliidipennis were first state records and Pastrongylus rufotuberculatus was a first local record. Conclusions. These findings stress the importance of studying the biology of Triatominae and the need for permanent surveillance, to allow for up-to-date distribution records of Triatominae species in and around human dwellings, those adapting to human dwellings, and frequencies of those naturally infected by T. cruzi.
