Feral swine may serve as T. cruzi reservoirs in Texas; hypothesis-generating for Chagas ecology and requires prospective confirmation.
Cross-Sectional (n=78)
Yes
Feral swine in Texas can serve as reservoirs for T. cruzi, the agent of Chagas disease, with a 6% infection prevalence detected in cardiac tissue.
Comeaux et al. (2016) conducted a cross-sectional in Trypanosoma cruzi infection (n=78). Feral swine was evaluated on Prevalence of T. cruzi infection based on PCR evaluation of cardiac tissue. T. cruzi infection was detected in 6% (3 of 54) of feral swine cardiac tissue samples by PCR, with all positive pigs originating from counties with documented kissing bug occurrence.
