The prevalence of fleas and gastrointestinal parasites in free-roaming and domestic cats in central Mexico was evaluated. Three hundred and fifty eight cats captured in the street or brought in by owners to the Animal Control Center Unit, a unit of State Government, from June 2010 to May 2011, were included in the study. All cats were examined for the presence of fleas and gastrointestinal worms. One-hundred and ninety (53%) cats were infested with at least one flea species. Single infestations were observed in 106 (30%) cats and mixed infestations in 84 (23%) cats. Four species of fleas were recovered: Ctenocephalides felis in 53% of the cats, C. canis in 18%, Echidnophaga gallinacea in 7% and Pulex irritans in 1%. One-hundred and sixty three (45%) cats were infected with one or more species of gastrointestinal parasites: 48 (13%) with nematodes, 145 (40%) with cestodes, and one animal presented Moniliformis moniliformis. Prevalences and mean intensity of infection were: Physaloptera praeputialis 7 and 18; T. cati 3 and 2; Ancylostoma tubaeforme 2.5 and 2; Toxascaris leonina 0.5 and 2; Dipylidium caninum 36 and 32; Taenia taeniformis 4 and 3 and Moniliformis moniliformis 0.3 and 106, respectively. There was significant association (P<0.01), between season and ectoparasites load, more fleas were obtained in the summer and autumn than in the winter and spring; however, no statistical difference was observed for endoparasites load (P>0.05). The correlation between the total number of ectoparasites and endoparasites was not significant (r = 0.089, P = 0.094).
评估了中美洲自由放养和家养猫中跳蚤和胃肠道寄生虫的流行情况。2010 年 6 月至 2011 年 5 月，从街头捕获或主人带到动物控制中心单位（州政府的一个单位）的 358 只猫被纳入研究。所有猫都检查了跳蚤和胃肠道蠕虫的存在。190 只（53%）猫至少有一种跳蚤物种寄生。106 只（30%）猫观察到单一感染，84 只（23%）猫观察到混合感染。共回收 4 种跳蚤：53%的猫中存在猫栉首蚤，18%的猫中存在犬栉首蚤，7%的猫中存在禽刺螨，1%的猫中存在人蚤。163 只（45%）猫感染了一种或多种胃肠道寄生虫：48 只（13%）感染线虫，145 只（40%）感染绦虫，1 只动物感染Moniliformis moniliformis。感染率和平均感染强度分别为：Physaloptera praeputialis 7 和 18；T. cati 3 和 2；Ancylostoma tubaeforme 2.5 和 2；Toxascaris leonina 0.5 和 2；Dipylidium caninum 36 和 32；Taenia taeniformis 4 和 3 以及Moniliformis moniliformis 0.3 和 106。季节和外寄生虫负荷之间存在显著关联（P<0.01），夏季和秋季的跳蚤比冬季和春季多；然而，内寄生虫负荷无统计学差异（P>0.05）。外寄生虫总数与内寄生虫总数之间无显著相关性（r = 0.089，P = 0.094）。
