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.
本研究的目的是确定墨西哥金塔纳罗奥州卡尔拉克地区犬类中针对[具体物种]的血清阳性率及其相关因素。从118只犬采集血清样本，并用于间接免疫荧光试验，以检测针对[具体物种]的抗体。使用问卷获取与血清阳性率相关的可能变量的信息。通过卡方检验和逻辑回归分析这些变量。犬类针对[具体物种]抗体的血清阳性率为64%（75/118）。52%（61/118）的犬有蜱虫感染，被鉴定为[蜱虫种类]。36%的犬出现贫血。还观察到白细胞减少（2.5%）、血小板减少（70%）和出血（14%）。贫血犬中有31%（23/75）、白细胞减少犬中有4%（3/75）、血小板减少犬中有80%（60/75）、出血犬中有17%（13/75）以及有蜱虫感染的犬中有59%（44/75）针对[具体物种]抗体呈阳性。与血清阳性率相关的因素为年龄（1 - 3岁和大于3岁，OR分别为7.77和15.39）、蜱虫感染（OR = 3.13）和血小板减少（OR = 3.36）。总之，卡尔拉克社区中[具体物种]的血清阳性率较高，其相关因素为年龄、蜱虫感染和血小板减少。
