Abstract
BackgroundThe American trypanosomiasis is a zoonosis caused by the protozoa Trypanosoma cruzi (T. cruzi). The disease is widely distributed throughout the American continent, affecting a wide range of hosts, including dogs. It is present in the canine population in the State of Yucatan, Mexico. However, no significant studies in owned dogs have been performed in the metropolitan area of Merida. A transversal study was conducted in 370 owned dogs from Merida, Yucatan, Mexico.MethodsA cross-sectional study including 370 dogs was performed in a major city of Yucatan, Mexico, to detect IgG antibodies against T. cruzi. A commercial ELISA test kit was used and a chi-square test used to evaluate associated risk factors; odds ratio (OR) and 95 % confidence interval (CI) were also estimated.ResultsThe indirect ELISA and western blot (WB) tests were used to detect specific immunoglobulin G antibodies against T. cruzi in serum samples. A prevalence of 12.2 % was found; age and area of residence were statistically associated with seropositivity in dogs (p <0.05).ConclusionsResults from the present study suggests the presence and abundance of the vector in urban conditions where a high number of seropositive cases of T. cruzi cases were found.
Highlights
The American trypanosomiasis is a zoonosis caused by the protozoa Trypanosoma cruzi (T. cruzi)
The prevalence of T. cruzi has been widely reported in urban dogs, most of the studies were based on stray dogs from cities or villages, or a low number of owned dogs were included
A survey conducted on 148 stray dogs and 114 pet dogs in a similar city from the Yucatan Peninsula (Campeche) reports T. cruzi seroprevalences of 9.5 and 5.3 %, respectively [14]

The disease is widely distributed throughout the American continent, affecting a wide range of hosts, including dogs. It is present in the canine population in the State of Yucatan, Mexico. No significant studies in owned dogs have been performed in the metropolitan area of Merida. A transversal study was conducted in 370 owned dogs from Merida, Yucatan, Mexico. Chagas disease, is a zoonosis of public health concern caused by the protozoon Trypanosoma cruzi and transmitted by a bloodsucking bug from the Triatominae subfamily. In Yucatan, Mexico, the disease is endemic and affects a wide range of hosts, including dogs and humans [1, 2].
