Ma. Demuro et Fg. Priest, PHYLOGENETIC ANALYSIS OF BACILLUS-SPHAERICUS AND DEVELOPMENT OF AN OLIGONUCLEOTIDE PROBE SPECIFIC FOR MOSQUITO-PATHOGENIC STRAINS, FEMS microbiology letters, 112(2), 1993, pp. 205-210
The 16S rRNA gene sequences for six strains of Bacillus sphaericus rep
resenting five distinct DNA homology groups and one strain of Bacillus
fusiformis have been determined. An oligonucleotide probe based on th
e area approximately between position 186 and 198 (Escherichia coli nu
mbering) of the 16S rRNA gene of the mosquito pathogen, strain 2362, h
ybridised to DNA from strains of DNA homology group IIA which contains
all known mosquito pathogens and not to any of ten other Bacillus spe
cies. It can be used to identify potential mosquito-pathogenic strains
of B. sphaericus in screening programmes.
