C.  aToxicity assessment and clearance of Brazilian microbial pest control agents in mice.  c2009  aPublicado online em 9 de julho de 2009.  aABSTRACT: The environmental toxicology of chemical pesticides have increased interest in the development and use of microbial pest control agents. In the present studt four new Brazilian strains of Bacillus and one fungus were tested to evaluate the acute oral toxicity and clearance of these microbials in C57BL6 mice. No mortality was observed after exposure for any of the microorganisms tested. Clearance was significant after 30 days but for one strain of B. thuringiensis and one of B. sphaericus this time was not enough to completely eliminate the spores.  aToxicologia  aBiopesticida1 aOLIVEIRA, R.
