The strain 273 B, the type strain of a H serotype of Bacillus thuringiensis not yet characterized: B. thuringiensis subsp. cameroun, serotype H32, was isolated from soil samples collected in Cameroon. This strain produces cuboidal parasporal bodies composed of two major proteins of 53 kDa and 35 kDa. N-terminal sequences of the major proteins share no homology with published sequences. Only the 35 kDa protein is susceptible to digestion by trypsin. A complex array of 9 plasmids was revealed.
