In developing countries, treatment of acute lymphoblastic leukaemia (ALL) usually relies on different immunophenotypic, cytogenetic and molecular subsets that have differing outcomes with different therapies. In Pakistan, treatment offered to patients is usually based on clinical features of disease at presentation.

Beta lactamases are the group of enzymes which are produced by some bacteria and they hydrolyze the β-lactam ring of the β-lactam antibiotics. Different strains of gram negative bacteria were isolated from these samples and identified as E. coli, Enterobacter and Klebsiella. Sensitivity of these bacterial strains was checked against different classes of antibiotics e. g. aminoglycosides, cephalosporins, carbapenems and trimethoprim-sulfamethoxazole by disc diffusion technique. These strains were analyzed for the production of beta lactamases which was then confirmed by double disc...
