Aa. Yousten et Ke. Rippere, DNA SIMILARITY ANALYSIS OF A PUTATIVE ANCIENT BACTERIAL ISOLATE OBTAINED FROM AMBER, FEMS microbiology letters, 152(2), 1997, pp. 345-347
Bacterial isolate BCA16, a putatively ancient bacterium apparently rec
overed from the abdominal contents of an insect preserved in amber, wa
s identified by DNA similarity analysis as belonging to similarity gro
up III of the Bacillus sphaericus complex. Thus, it is closely related
to strains of this species frequently isolated from soil. Although so
me strains of B. sphaericus are pathogenic for mosquito larvae, isolat
e BCA16 is nonpathogenic.
