为了解芜湖市区宠物犬、猫刚地弓形虫感染情况,于2019年5—10月在芜湖市某宠物医院采集宠物犬、猫血样,应用环介导等温扩增（LAMP）技术检测宠物犬、猫弓形虫感染情况。共采集500份宠物犬、猫血样,阳性血样26份,阳性率为5.2%。宠物犬、猫阳性率分别为2.8%（7/250）和7.6%（19/250）,二者差异有统计学意义（χ² = 5.842,P < 0.05）。雄性和雌性宠物犬的阳性率分别为2.7%（4/147）和2.9%（3/103）,齿龄 ≤ 3和 > 3的阳性率分别为2.4%（4/166）和3.6%（3/84）,差异均无统计学意义（χ² = 0.000、0.014,P > 0.05）。雄性和雌性宠物猫的阳性率分别为8.3%（10/120）和6.9%（9/130）,差异无统计学意义（χ² = 1.177,P > 0.05）,齿龄 ≤ 3和 > 3的阳性率分别为6.5%（12/185）和10.8%（7/65）,差异有统计学意义（χ² = 1.256,P < 0.05）。提示芜湖市区宠物犬、猫弓形虫感染率较高,存在感染人的可能。

Peripheral blood samples were collected from pet dogs and cats at a veterinary clinic in Wuhu from May to October, 2019, to investigate the prevalence of Toxoplasma gondii in pet dogs and cats in Wuhu urban area. Loop-mediated isothermal amplification (LAMP) technology was used to detect Toxoplasma gondii in pet dog and cat samples. T. gondii were detected from 26 of the 500 samples. The overall positive rate is 5.2% with 2.8% (7/250) for dogs, and 7.6% (19/250) for cats, respectively, the difference was statistically significant (χ ² = 5.842, P < 0.05). The positive rate in male and female pet dogs was 2.7% (4/147) and 2.9% (3/103), respectively, the positive rates in younger pet dogs (age ≤ 3 years) and elder dogs (age > 3 years) were 2.4% (4/166) and 3.6% (3/84), respectively, with no statistically significant difference (χ ² = 0.000, 0.014, P > 0.05). The positive rates in male and female cats were 8.3% (10/120) and 6.9% (9/130), respectively, with no statistically significant difference (χ ² = 1.177, P > 0.05). The positive rates in younger pets (age ≤ 3 years) and elder pets (age > 3 years) were 6.5% (12/185) and 10.8% (7/65), respectively. The difference was statistically significant (χ ² = 1.256, P < 0.05). The results suggested a relatively high prevalence of T. gondii in dogs and cats in Wuhu urban area, which may potentially infect human.
