ABSTRACT
E. coli, often highly pathogenic in neonatal and immuno-compromised patients, are usually supposed susceptible to a variety of chemotherapeutic agents, however with the time and also due to the extensive use of chemotherapeutic agents irrespective of their susceptibility, have evolved drug resistant strains. Moreover, the production of extended spectrum β-lactamases producing enteric pathogens is a serious issue. In this context the present study was conducted to find out occurrence of extended spectrum Beta-lactamases producing alpha hemolytic Escherichia coli in neonates, of less than one month of age, suffering from diarrhea. Fecal samples were collected from various private hospitals in Mathura and Agra districts of Uttar Pradesh, India. With the help of hospital nursing staffs sterilized stool samples were collected and processed for isolation of E. coli. The double disk diffusion method was applied to assess the ESBL production. E. coli organisms were isolated from 39 kids out of 120 samples. The assessment of isolates revealed alpha hemolytic nature of 23 isolates on 5% sheep blood agar. As usual when drug sensitivity was performed that revealed their multi drug resistance pattern which on further examination with double disk method showed 17 of them to be extended spectrum β-lactamases producing E. coli. The presence of enterohemorrhagic extended spectrum β-lactamases producing Escherichia coli in kids is a matter of concern and public health importance as it may be due to the transmission from hospital itself during the birth time or post birth admission period.
