Penicillin-resistant mechanisms in Pseudomonas aeruginosa: effects of penicillin G and carbenicillin on transpeptidase and C -alanine carboxypeptidase activities.

abstract：:Emergence of resistance to pentavalent antimonials has become a severe obstacle in the treatment of visceral leishmaniasis (VL) on the Indian subcontinent. The mechanisms operating in laboratory-generated strains are somewhat known, but the determinants of clinical antimony resistance are not well understood. By utili...
