ESBL producing K. pneumoniae and E. coli were frequently isolated from all the sites of samples from the NICU. Table 4 details the no. of isolates from each site. It is significant to note that ESBL producing strains were always isolated from one of the incubators, phototherapy units, suction apparatus and trolley.
