Abstract
The genus Aeromonas consists of glucose fermenting, Gram
negative rod that are widespread in freshwater environments and isolated from
clinical, environmental and food samples, where they can grow even at low
temperatures. Different researchers across the globe have been isolating Aeromonas
bacteria from various infection sites of cold and warm-blooded animals,
including humans. In the present study, twenty-one Aeromonas sp. were
isolated from two different locations of a polluted river in the northern part
of West Bengal and later on, the antibiotic sensitivity of these bacteria was
assessed. Out of these twenty-one bacterial isolates, twenty were found to be Aeromonas
hydrophila and one belonged to Aeromonas caviae. Antibiotic
sensitivity of all the bacterial isolates were examined and it was seen that
all the isolates were resistant to ampicillin and sensitive to gentamycin and
novobiocin. 57.1% isolates were resistant to erythromycin, 23.8% isolates were
resistant to clindamycin and 19.04% were resistant to nalidixic acid and
cephalothin. Our findings reveal a high prevalence of antibiotic resistance in Aeromonas
isolates collected from a polluted river, indicating the indiscriminate use
of antibiotics in the study area.
