Associated Factors to Seroprevalence of spp. in Dogs of Quintana Roo, Mexico.

The objective of this study was to determine the seroprevalence to spp. in dogs from Xcalak, Quintana Roo, Mexico, and the associated factors. Serum samples were obtained from 118 dogs and used in an indirect immunofluorescent assay test for the detection of antibodies against spp. A questionnaire was used to obtain information about possible variables associated with seroprevalence. These variables were analyzed through Chi test and logistic regression. Dog seroprevalence of antibodies against spp. was 64% (75/118). Fifty-two percent (61/118) of dogs had tick infestation which was identified as . Anemia was observed in 36% of dogs. Leucopenia (2.5%), thrombocytopenia (70%), and hemorrhage (14%) were also observed. Thirty-one percent (23/75) of dogs with anemia, 4% (3/75) of dogs with leucopenia, 80% (60/75) of dogs with thrombocytopenia, 17% (13/75) of dogs with hemorrhages, and 59% (44/75) of dogs with ticks were positive for spp. antibodies. The factors associated with seroprevalence were age (1-3 and >3 years old, OR = 7.77 and OR = 15.39, resp.), tick infestation (OR = 3.13), and thrombocytopenia (OR = 3.36). In conclusion, seroprevalence of spp. was high in the community of Xcalak and its associated factors were age, tick infestation, and thrombocytopenia.
