Association between presence of bla_CTX-M and bla_VIM genes with multidrug resistance (MDRs), ESBL production (ESBLp) and MBL production (MBLp) among E. coli and Salmonella spp. Note: # either all or no resistance was detected, hence, P-value could not be analyzed; p: Phenotypically confirmed, *: Significant at 5% level of significance.
