Partial characterization of a cubic Bacillus phage. Can. J. Microbiol. 24: 986--993. Phage Bam35 is an icosahedron of about 63 nm in diameter. It has a double capsid with spikes at the vertices, and a tail which seems to appear upon nucleic acid ejection. The phage contains DNA and, probably, lipids which seem to be located in the inner coat. The phage is(More)
Forty-eight strains of Bacillus thuringiensis and 12 strains of B. cereus were treated with ultraviolet light and mitomycin C. The former agent was the more effective inducer. Bacillus thuringiensis produces at least seven different phage particles with long, non-contractile tails. The frequencies of lysogeny and polylysogeny are 83 and 25% respectively.(More)

Deposit assessment after aerial spraying with Bacillus thuringiensis (B.t.) formulations consists of the analysis of the splash of droplets on Kromekote papers and determining the number of bacterial colonies growing on nutrient agar medium Petri dishes. However, neither of these two methods provides a number of spores deposited although this figure is(More)
