tailieunhanh - Isolation and molecular identification of Escherichia coli in diarrheic captive Asian elephants (Elephas maximus) of Tamil Nadu State, India

The main objective of the present study was isolation and molecular identification of Escherichia coli in diarrheic captive Asian elephants (Elephas maximus) of Tamil Nadu state. Isolation and identification of was carried out in both fresh water and dung samples from diarrheic cases of captive elephants (n=8), using standard microbiological culturing method and PCR technique. Out of dung (n=8) and water (n=8) samples, (n=5) of water samples as well as (n=5) of the dung samples were found to be positive for Escherichia coli. On MacConkey Agar, the typical lactose fermenting foul smelling pink coloured colonies indicated the growth of . In Eosin-Methylene blue agar, the colonies appeared as blackish centres with a metallic sheen indicating the growth of . Molecular identification of by Polymerase Chain reaction (PCR), the amplicon size was findings in this study indicated the need for supply of good quality water to the captive elephants, in order to minimize the possible incidences of contamination of Escherichia coli. | Isolation and molecular identification of Escherichia coli in diarrheic captive Asian elephants (Elephas maximus) of Tamil Nadu State, India
