| Abstract: |
| 本文报道了对感染HBV阳性血液的38只日本医蛭(Hirudo nipponica Whitman)的体液HBsAg检出率和GMT(几何平均滴度)观察19周的结果。共检查13次,HBsAg的平均检出率为64.77%。GMT在1:28.21~1:64之间。检出结果表明在湖北,HBV至少可在蚂蝗体内存活19周。GMT在最初七周较高,此后逐渐降低,直至最低,后来又慢慢升高,推想是病毒在蚂蝗体内复制的表现。蚂蝗在吸血或转移吸血时,容易传播乙型肝炎,建议水田作业时,应防止蚂蝗叮咬。 |

| In this paper we reported an observation on 38 leeches (Hirudo nipponica Whitman) fed artificially in blood containing HBsAg. The positive rate and geometric mean titer (GMT) of HBsAg of leeches were observed for 19 weeks. The humores of the leeches were tested for 13 times by using RPHA. The average positive rate is 64.77%, GMT varies between 1:28.21 and 1:64. It is shown that HBV may lives at least for 19 weeks in leeches' body in Hubei Province. The GMT is higher in the initial seven weeks, gradnally decreased till to the lowest and then gradually increased at last. It is postulated that HBV could be replicated in the leeches. Hepatitis B may be spread by leeches when sucking. We suggest that it is necessary to avoid bite by the leeches when people are working at wet field. |
