The frequency of gastrointestinal infections in 502 cats seen at the Veterinary Hospital of the University of São Paulo, SP, Brazil, between 2005 and 2014, was measured. The samples were analyzed using methods of flotation and sedimentation. The results were compared with those from studies published previously using fecal samples from the same hospital at different times. Associations between the frequency of positivity for each parasite and age, breed, sex, diarrhea and use of anthelmintic were investigated (chi-square or Fisher's exact tests). A partitioned chi-square test was used to compare different periods. Cryptosporidium spp., Giardia spp., Cystoisospora spp. and Sarcocystis spp. were the most common parasites, followed by Toxocara cati and Ancylostoma spp. Cryptosporidium spp. presented higher frequency in young cats and Sarcocystis spp. with the presence of diarrhea (p < 0.05). Results from this study with previous periods showed that the frequencies of Cryptosporidium spp., Cystoisospora spp. and T. cati were lower (p < 0.05) than those observed in previous periods. The frequencies of Giardia spp. and Ancylostoma spp. were similar to the results found in the preceding period and lower than the values found for the other periods (p < 0.05). The reasons for these changes should be investigated.
对2005年至2014年期间在巴西圣保罗大学兽医院就诊的502只猫的胃肠道感染频率进行了测量。样本采用浮选法和沉淀法进行分析。将结果与之前使用该医院不同时期粪便样本发表的研究结果进行比较。研究了每种寄生虫阳性频率与年龄、品种、性别、腹泻和使用驱虫药之间的关联（卡方检验或费舍尔精确检验）。采用分割卡方检验比较不同时期。隐孢子虫属、贾第虫属、等孢球虫属和肉孢子虫属是最常见的寄生虫，其次是猫弓首蛔虫和钩口线虫属。隐孢子虫属在幼猫中出现频率较高，肉孢子虫属在有腹泻症状时出现频率较高（p<0.05）。本研究与之前时期的结果表明，隐孢子虫属、等孢球虫属和猫弓首蛔虫的频率低于之前时期（p<0.05）。贾第虫属和钩口线虫属的频率与上一时期的结果相似，且低于其他时期的值（p<0.05）。应调查这些变化的原因。
