| Abstract: | Phylogenetic analysis using the gyrB sequence was performed to investigate the genetic relevance among 49 isolates of P. pneumotropica. In the phylogeny, the isolates were clearly classified into three groups as follows: group A for the isolates of biotype Jawetz derived from mice, group B for the isolates of biotype Jawetz derived from rats, and group C for the isolates of biotype Heyl. These results suggest that the gyrB sequence of P. pneumotropica differs between the isolates of two biotypes, and also between the isolates derived from mice and rats in the biotype Jawetz. |
