Acute Chagas' cardiopathy in a polar bear (Ursus maritimus) in Guadalajara, Mexico

Abstract: We report a 24 year old female polar bear (Ursus maritimus) who contracted Chagas' infection at the Guadalajara Zoo, in Jalisco, México, and died of acute Chagas' carditis 15 days later. The histopathological findings are described, as well as the presence of triatomines (Triatoma longipennis Usinger) infected with Trypanosoma cruzi collected within 5 meters from the place where the animal lived in the city of Guadalajara.

“…T. cruzi is an important public health concern in Latin America, where 10-12 million people are estimated to be infected (Morel and Lazdins 2003). In North America, T. cruzi is commonly detected in several species of mammalian wildlife, and is increasingly diagnosed in domestic dogs and exotic animals (Kasa et al 1977, Jaime-Andrade et al 1997, Meurs et al 1998, Kjos et al 2008. Autochthonous cases in humans are rare, with only six cases previously reported (Herwaldt et al 2000, Dorn et al 2007; however, serologic studies indicate that many autochthonous cases may be undiagnosed (Woody et al 1965, Burkholder et al 1980, Stramer et al 2007, Bern et al 2008).…”

“…Investigation of polar bears in Hudson Bay, where they are harassed by several species of biting insects (Derocher and Stirling 1990, Clark and others 1997), may, however, provide evidence of trypanosomes. As reported by Jamie‐Andrade and others (1997), polar bears forced to live in other regions of the world might become infected by Trypanosoma species present in those areas.…”

“…This was done in association with other investigations involving blood sampling. After this study was initiated, a report of a T cruzi infection in a polar bear in a zoo in Mexico was published (Jaime‐Andrade and others 1997). However, this species is transmitted by reduviid bugs, a family of insects confined to the tropical areas of the world.…”
