The problem: The effects of microwave radiation on the infectivity of "Trichinella spiralis" in young, white, laboratory mice were studied. Procedure. Mice were divided into two groups: 1) mice receiving isolated, ...

The Problem. "Bacillus cereus" strain T accumulates an intracellular polysaccharide during late logarithmic and early stationary phases of the growth cycle. The polysaccharide is subsequently degraded during the ...

The K88ac antigen, thought to he a pilus on "Escherichia coli", has been determined to be one of the virulence factors in neonatal porcine colibacillosis. Using five different "E. coli" strains, the suppression of this ...
