Toxocara canis can cause blinding eye disease. This study assessed the presence of T. canis eggs in soil from parks in Melbourne and also the incidence of presumed ocular toxocariasis in Victoria.
One hundred and eighty soil samples were collected from nine suburban locations in Melbourne, Australia. These were analyzed for the presence of T. canis eggs. A search of laboratory records of T. canis serology requests from Victorian patients over an 8-year period was performed.
Only one soil sample was positive for T. canis eggs. Positive T. canis serology was reported in 13 samples from patients. These patients all had ocular features suggestive of T. canis infection.
Toxocara canis eggs are rare in public parks in Melbourne and symptomatic ocular toxocariasis is uncommon in the Victorian population. The acquisition of the disease is unlikely to be from public parks.
犬弓首蛔虫可导致致盲性眼病。本研究评估了墨尔本公园土壤中犬弓首蛔虫卵的存在情况以及维多利亚州疑似眼弓蛔虫病的发病率。
从澳大利亚墨尔本的9个郊区地点采集了180份土壤样本。对这些样本进行犬弓首蛔虫卵检测。对维多利亚州患者8年期间犬弓首蛔虫血清学检测申请的实验室记录进行了检索。
仅1份土壤样本检测出犬弓首蛔虫卵呈阳性。有13例患者的犬弓首蛔虫血清学检测呈阳性。这些患者均具有提示犬弓首蛔虫感染的眼部特征。
犬弓首蛔虫卵在墨尔本的公园中很少见，有症状的眼弓蛔虫病在维多利亚州人群中并不常见。该病不太可能通过公园感染。
