“…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).…”

Trypanosoma cruzi, the causative agent of Chagas' disease, is a substantial public health concern in Latin America. Although rare in humans and domestic animals in the United States, T. cruzi is commonly detected in some wildlife species, most commonly raccoons (Procyon lotor) and Virginia opossums (Didelphis virginiana). To increase our understanding of the reservoir host species range and geographic distribution, 11 species of mammals from six states spanning the known range of T. cruzi (Arizona, California, Florida, Georgia, Missouri, and Virginia) were tested for antibodies to T. cruzi using indirect immunofluorescent antibody testing. In addition, culture isolation attempts were conducted on a limited number of animals from Georgia and Florida. Evidence of T. cruzi was found in every state except California; however, low numbers of known reservoirs were tested in California. In general, the highest seroprevalence rates were found in raccoons (0-68%) and opossums (17-52%), but antibodies to T. cruzi were also detected in small numbers of striped skunks (Mephitis mephitis) from Arizona and Georgia, bobcats (Lynx rufus) from Georgia, two coyotes (Canis latrans) from Georgia and Virginia, and a ringtail (Bassariscus astutus) from Arizona. Culture-based prevalence rates for raccoons were significantly greater than those for opossums; however, seroprevalences of raccoons and opossums from several geographic locations in Georgia and Florida were not different, indicating that exposure rates of these two species are similar within these areas. For both raccoons and opossums, seroprevalence was significantly higher in females than in males. No difference was detected in seroprevalence between adults and juveniles and between animals caught in urban and rural locations. Our results indicate that T. cruzi prevalence varies by host species, host characteristics, and geographic region and provides data to guide future studies on the natural history of T. cruzi in the United States.

“…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.…”

“…There are limited data on the parasite fauna of polar bears. Only nine parasites have been reported from this host (Rogers and Rogers 1976, Garner and others 1997, Jaime‐Andrade and others 1997), and of these, only the nematode Trichinella spiralis (probably Trichinella nativa ) has been reported in wild polar bears (Madsen 1961, Kjos‐Hanssen 1984, Kumar and others 1990).…”

Chagas disease in the state of Jalisco, Mexico was described for the first time in 1967; however, knowledge on the disease remains in a slow process. Between 1967 and 2006, the disease was described in its acute and chronic forms. The vector species have been identified, and the parasite Trypanosoma cruzi has been isolated and genetically characterized. Also, the magnitude of the infection in humans has been determined through serological studies of different populations as well as of blood donors. The up-to-dateness of knowledge of the disease in the state of Jalisco, unveils a necessity of increased research on the epidemiology of Chagas disease as well as on clinical studies to assess the health of individuals and the populations.
