摘要
用直接压片法和人工消化法检查了海口集贸市场上 5种淡水鱼 (鲫鱼、罗非鱼、鲤鱼、土鲮鱼、白鲳 )感染华枝睾吸虫囊蚴情况。结果表明 :5种淡水鱼的总感染率为 5 3 66%。其中 ,鲤鱼、土鲮鱼、鲫鱼、罗非鱼、白鲳的感染率分别为 68 75 %、5 8 82 %、5 8 0 6%、4 8 5 7%和 36 67% ;平均每克鱼肉含囊蚴数最高的是鲫鱼 ( 9 4 7个 g) ,平均每尾阳性鱼含囊蚴数最高的是土鲮鱼 ( 4 3个 尾 )。
Five species of freshwater fish, Carassius auratus, Tilapia mossambila, Cyprinus carpio, Cirrhius molitorella and Ephippus orbis in trading markets of Haikou were examined for metacercaria (Clonorchis sinensis) by the methods of direct pressing slice and artificial digestion. The total rate of infection was 53.66%. 68.75%, 58.82%, 58.06%, 48.57% and 36.67% in Cyprinus carpio, Cirrhius molitorella, Carassius auratus, Tilapia mossambila and Ephippus orbis respectively. On average, the number of metacercarias per gram was highest in Carassius auratus but infected Cirrhius molitorella had the highest number of metacercarias in terms of absolute parasite numbers.
