ProMED翻訳情報(199回) ~台湾における狂犬病に関してのイタチアナグマの生態からみた意見(8月13日)~

The solitary lifestyle and reclusive habits of the ferret-badger suggest to me that we may be looking at maternal transmission of an exceptionally slowly emerging rabies strain, which would not become evident until a significant number of ferret-badgers were infected and behaving abnormally. Otherwise, my understanding is that ferret-badgers have very little to do with each other, or with other animals, and so transmission from ferret-badger to ferret-badger after they reach maturity and disperse would be unlikely.

Bats are fairly commonly blown back and forth from mainland China, so what I’m thinking is that there may be a bat rabies strain that has mutated to infect ferret-badgers, and was separately passed to ferret-badgers on either side of the Straits of Formosa. But it would have to be a strain with a very long latency interval.かなり一般的に、コウモリは中国本土から行ったり来たりしている。そのため、私は、イタチアナグマに感染するように変異し、台湾海峡のそれぞれの側で別々にイタチアナグマに継代されたコウモリ狂犬病ウイルス株が存在するかもしれないと考えている。しかし、それらは大変に長い潜伏期間をもったウイルス株に違いない。

Even maternal transmission poses certain problems, in that the ferret-badger litter size is only 2-3. But so far as I know, littermates are the only other ferret-badgers that any ferret-badger is likely to encounter except at mating time.

Ferret-badgers are most often born in May and June, and this outbreak appears to have emerged just about the time that the young ferret-badgers would be setting off to find their own habitat.

[Until the Taiwanese authorities release more detailed information on their surveillance activities, it will remain uncertain whether this outbreak of rabies virus infection in the Formosan ferret-badger population of Taiwan is the outcome of a recent introduction, or has remained undetected for a long period as a consequence of the ecological isolation of these animals. The outcome of genomic studies, which may help to establish the origin of the outbreak strain, is awaited. – Mod.CP
