“…T. cruzi infection in domestic dogs has been reported widely throughout the southern United States since 1972 (Fig. 4C) (18,20,23,41,105,134,150,189,205,206,239,274,287,298,312). Infection has been documented in at least 48 different breeds in the United States, with the sporting and working breeds accounting for the majority of cases, presumably due to greater exposure to infected vectors and mammalian tissues (150,246).…”

Trypanosoma cruzi and Chagas' Disease in the United States

et al. 2011

SUMMARY Chagas' disease is caused by the protozoan parasite Trypanosoma cruzi and causes potentially life-threatening disease of the heart and gastrointestinal tract. The southern half of the United States contains enzootic cycles of T. cruzi , involving 11 recognized triatomine vector species. The greatest vector diversity and density occur in the western United States, where woodrats are the most common reservoir; other rodents, raccoons, skunks, and coyotes are also infected with T. cruzi. In the eastern United States, the prevalence of T. cruzi is highest in raccoons, opossums, armadillos, and skunks. A total of 7 autochthonous vector-borne human infections have been reported in Texas, California, Tennessee, and Louisiana; many others are thought to go unrecognized. Nevertheless, most T. cruzi -infected individuals in the United States are immigrants from areas of endemicity in Latin America. Seven transfusion-associated and 6 organ donor-derived T. cruzi infections have been documented in the United States and Canada. As improved control of vector- and blood-borne T. cruzi transmission decreases the burden in countries where the disease is historically endemic and imported Chagas' disease is increasingly recognized outside Latin America, the United States can play an important role in addressing the altered epidemiology of Chagas' disease in the 21st century.

“…Enrollment criteria for our study included dogs >6 months of age within 4 days of admittance to shelters. We detected exposure to T. cruzi using Chagas STAT-PAK, a commercially available rapid immunochromatographic test (Chembio Diagnostic Systems, Inc., Medford, NY, USA) that has been validated for use in dogs ( 9 ) and has high sensitivity and specificity when compared with conventional serologic techniques ( 10 ). To detect parasite DNA within blood, we followed this process: a 200-μL aliquot of centrifuged blood, including the buffy coat, from a subset of seropositive and seronegative dogs across all shelters was subjected to DNA extraction and used as the template in a real-time quantitative PCR with a TaqMan probe to amplify a 166-bp repetitive sequence of satellite DNA specific to T. cruzi ( 11 ).…”

“…T. cruzi -Detect is rapid and easy to use and it has been suggested as a good screening tool for T. cruzi infection in dogs in the field. [81417] However serological tests should be coupled to confirmatory tests. [1718] The observed prevalence using OligoC-TesT was lower (8.8%; 9/102).…”

Molecular and serological rapid tests as markers of Trypanosoma cruzi infection in dogs in Costa Rica

et al. 2014

View full text Add to dashboard Cite

Introduction:Chagas disease is a zoonotic disease caused by Trypanosoma cruzi and dogs are one of the main domestic reservoirs.Materials and Methods:One molecular (OligoC-TesT, Coris Bioconcept) and one serological (T. cruzi-Detect, Inbios) rapid tests were evaluated as infection markers for T. cruzi in 102 dogs living in eight villages endemic for Chagas in Costa Rica.Results:T. cruzi-Detect performed well as screening tool with 23.3% positive samples. The large number of invalid results (66.7%) observed in samples tested with OligoC-TesT precluded assessing the use of this new method as epidemiological tool to detect T. cruzi infection in dogs.
