The occurrence of Giardia duodenalis in cats is of potential significance from both clinical and public health perspectives. The object of this study was antigenic detection of G. duodenalis in household cats of Ahvaz district, South-West of Iran.
The prevalence of G. duodenalis was determined in fecal samples by two techniques: centrifugation-flotation and a commercial Giardia Antigen Test Kit (immunochromatography assay) in 150 household cats of different ages among referred cases to Veterinary Hospital of Ahvaz University from January 2008 to February 2010.
Five out of 150 fecal samples (3.33%) were positive for antigen of G. duodenalis by immunochromatography assay. The prevalence was significantly higher in young cats less than 6 months (15.79%) compared with adult cats 6 months - 3 years (1.37%) (P=0.027) and above 3 years (1.72%) (P=0.044). The infection had more prevalence in diarrheic cats (17.39%) compared with non-diarrheic cats (0.79%) and the difference was significant (P=0.02) as well. The prevalence was higher in male cats (3.41%) than females (3.23%) and in the season of autumn (6.06%), but the difference was not significant between the prevalence of infection relative to host gender and season (P>0.05). Microscopy examination on fecal samples showed that 2% of the studied cats were positive.
The parasite antigen was present as a zoonotic infection in Ahvaz district, South-west of Iran. More sensitive techniques, such as immunochromatography assay, might yield more reliable results, in the detection of low levels of Giardia in fecal samples of cats.
从临床和公共卫生角度来看，猫体内十二指肠贾第虫的出现具有潜在意义。本研究的目的是对伊朗西南部阿瓦士地区家猫中的十二指肠贾第虫进行抗原检测。
2008年1月至2010年2月间，在转诊至阿瓦士大学兽医院的150只不同年龄的家猫中，采用两种技术检测粪便样本中十二指肠贾第虫的感染率：离心漂浮法和商用贾第虫抗原检测试剂盒（免疫层析法）。
通过免疫层析法检测，150份粪便样本中有5份（3.33%）十二指肠贾第虫抗原呈阳性。6个月以下的幼猫感染率（15.79%）显著高于6个月至3岁的成年猫（1.37%）（P = 0.027）和3岁以上的成年猫（1.72%）（P = 0.044）。腹泻猫的感染率（17.39%）高于非腹泻猫（0.79%），差异也具有统计学意义（P = 0.02）。雄猫的感染率（3.41%）高于雌猫（3.23%），秋季的感染率（6.06%）较高，但感染率在宿主性别和季节方面的差异无统计学意义（P>0.05）。粪便样本的显微镜检查显示，2%的被研究猫呈阳性。
在伊朗西南部的阿瓦士地区，该寄生虫抗原作为一种人畜共患感染存在。在检测猫粪便样本中低水平的贾第虫时，免疫层析法等更敏感的技术可能会产生更可靠的结果。
