Abstract: Introduction: Many studies have evaluated risk factors for human visceral leishmaniasis, but few have focused on the infection among dogs. The objective of this study was to assess the association between peridomestic socioeconomic and environmental factors and the presence of dogs seropositive for Leishmania chagasi in the City of Teresina, Brazil. Methods: This case-control study was based on the results of a routine seroepidemiological survey among domestic dogs carried out in 2007. Serological tests were p… Show more

“…In this study, we observed that dogs residing in households with previous case of CVL showed a higher risk of infection than dogs residing in households with no previous cases. Similar results were observed in a study conducted in Teresina, Brazil, where in households with a history of dog removal by the program, the odds of having at least one infected dog were 5 times the odds in dwellings with no history of dog removal (da Silva et al, 2012). This result may have been due to an environment favorable to the development of the vector in the domiciles, causing the occurrence of new cases.…”

“…A previous study in the Bahia State did not find any association with local history of CVL and indicated other possible local risk variables such as the presence of other domestic and wild animals in the peridomicile 20 . In a case-control study, such association was observed even in residences that had sent dogs for euthanasia in the previous 12 months, and the authors justified this association by the ineffectiveness of euthanasia as a measure to control CVL 50 .…”

“…However, it is believed that seroconversion alone does not reflect the infectivity potential of the dogs and does not predict the progression of the infection to overt disease or to subpatent infection. It is important to mention that removing seropositive dogs without implementing environmental management measures does not prevent future infections in other animals [57].…”
