Presence of Extended Spectrum β-lactamases Producing α Haemolytic Escherichia coli in Yellow-wattled Lapwing (Vanellus malabaricus)

Abstract: Since last decade, there is increasing reports of presence of extended spectrum β-lactamases producing bacteria especially from enterobacteriacae family. The presence of Extended spectrum β-lactamases (ESBL) producing E. coli causes a serious public health threat to human beings. The present study reports the isolation of extended spectrum β-lactamases producing α hemolytic Escherichia coli in Yellow-wattled Lapwing (Vanellus malabaricus) chicks. Escherichia coli organisms were isolated from three chicks suffering from unusual clinical signs and died before rehabilitation in the month of August 2010. Further assessment of isolates revealed their ability to bind with Congo red dye on Tryptic soy agar media and α hemolytic nature on 5% chicken blood agar. As usual when drug sensitivity was performed it revealed their multi drug resistance pattern which on further examination with double disk method showed them to be extended spectrum β-lactamases producing Escherichia coli. The presence of enterohemorrhagic extended spectrum β-lactamases producing Escherichia coli in Yellow-wattled Lapwing is a matter of concern as it may be due to the transmission from human being as these Lapwings are residing in the close vicinity of university premises. Moreover, their nesting areas are also very near to the place where carcasses of dead animals were disposed off during that period of time. To the best or our knowledge, this appears to be the first report of pathogenic E. coli identified in Yellow-wattled Lapwing, implicating Yellow-wattled Lapwings as a new potential reservoir of these zoonotic pathogens.
