摘要

在拉丁美洲,恰加斯病是一个重大的公共卫生威胁,犬类在克氏锥虫的国内传播周期中发挥着重要作用。本报告介绍了一只两个月大的雄性杂种狗的查加斯病病例,这只狗被救出并被带到位于尼加拉瓜马那瓜市的私人皇家宠物兽医诊所。动物呈病毒质状态,虚弱且完全湿润,直肠温度33.6℃,脱水(9%),黏膜苍白,淋巴结无反应,腹部肿胀,触诊无痛,左胸腔溃疡灶带血。外周涂片检查检出血液寄生虫锥虫;此外,在PCR分析中,克氏锥虫获得扩增,而间日锥虫和伊文氏锥虫均阴性。发现和确认这一病例可以提高该国对报告犬类感染的重要性的认识,这是控制人间恰加斯病病例的流行病学监测计划的一部分。

Molecular identification of Trypanosoma cruzi in a naturally infected dog from Nicaragua
In Latin America, Chagas disease is a significant public health threat and canines play an important role in the domestic transmission cycles of Trypanosoma cruzi. This report presents a case of Chagas in a two-month-old male mongrel dog that was rescued and taken to the private Royal Pets Veterinary Clinic in the City of Managua - Nicaragua. The animal was in a cachectic state, weak and completely wet, presenting a rectal temperature of 33.6 ° C, dehydration (9%), pale mucous membranes, non-reactive lymph nodes, distended abdomen without pain on palpation, bloody ulcerative lesion in the left rib cage. In peripheral smear examination, the blood parasite Trypanosoma was detected; in addition, in the PCR analysis, amplification was obtained for Trypanosoma cruzi, but negative for Trypanosoma vivax and Trypanosoma evansi. The detection and identification of this case could raise awareness in the country about the importance of reporting canine infections as part of epidemiological surveillance programs to control human cases of Chagas disease.
