Sridhar, PY - 2009/10/28 Y2 - 2025/10/14 TI - Characterization, hemolysis and multidrug resistance among Aeromonas spp. isolated from Bhavani river, Erode, South India JF - Recent Research in Science and Technology JA - RRST VL - 1 IS - 1 SE - Articles DO - UR - https://www.updatepublishing.com/journal/index.php/rrst/article/view/288 SP - AB - <p class="MsoNormal" style="margin: 0in 0in 0pt; line-height: 200%; text-align: justify;"><span style="font-size: small; font-family: Times New Roman;">A total of 87 strains of <em style="mso-bidi-font-style: normal;">Aeromonas </em>spp. were identified biochemically. The strains were isolated from 50 samples of water from Bhavani river Erode, Tamil Nadu, India. In the present study among 87 <em style="mso-bidi-font-style: normal;">Aeromonas </em>spp. the prevalence strain was identified as <em style="mso-bidi-font-style: normal;">A.hydrophila </em>(60.9%), while the other strains belonged to the species <em style="mso-bidi-font-style: normal;">A. sobria </em>(20.7%), <em style="mso-bidi-font-style: normal;">A. caviae </em>(11.5%) and <em style="mso-bidi-font-style: normal;">A.salmonicida </em>(6.9%). The virulence factors like hemolysin, lipase, and serine protease were present in 96%, 93% and 94% of the strains respectively. Antibiotic susceptibility of <em style="mso-bidi-font-style: normal;">Aeromonas </em>spp. was determined by disc diffusion method. All <em style="mso-bidi-font-style: normal;">Aeromonas</em> spp. were examined for resistance against 16 antibiotics. All strains showed 100% of resistance to Ampicillin,Carbenicillin and Cephalothin. The highest resistances encountered were 91.9% to streptomycin,90.8% to polymyxin-B, 85% to rifampicin while the rest were under 50%.In contrast all the strains were sensitive to cefotaxime.The present work highlights the important incidence of <em style="mso-bidi-font-style: normal;">Aeromonas</em> spp., with virulence potential and antimicrobial resistance, isolated from river bhavani.</span></p> ER -
