Abstract
Enterococcus sp. was isolated from the midgut of silkworm against the germination ofNosema bombycis spores. Identification was based on the biochemical characteristics, 16S rDNA sequences analysis and species-specific probes ofEnterococcus spp. The isolated strains fermented sorbitol and arabinose but did not ferment raffinose.Enterococcus sp. was clustered together withEnterococcus mundtii ATCC 43188 and 100% sequence homology was found by 16S rDNA sequences BLAST analysis and constructing the phylogenetic tree. Comparison of the sequences of the 16S rDNA species-specific probes ofEnterococcus spp. with the 16S rDNA sequence of isolate revealed similar segment to the species-specific probe ofE. mundtii. So, we can make conclusion the 16S rDNA segment ofEnterococcus sp. can hybridise with species-specific probe ofE. mundtii. Enterococcus mundtii was detected for the first time in the intestine of silkworm.
