The effluents of the five different tanneries (TE-1, TE-2, T-3, TE-4 and TE-5) were investigated for the determination of Escherichia coli population along with to check the antibiotic, chromate and salinity resistance in isolates. All the samples contained high population of Escherichia coli isolates. The highest population was observed from the sample of tannery-2 (TE-2) which was 3.8 ± 0.96 ×106 cfu/mL. The Escherichia coli TE-2 isolate from TE-2 represented highest tolerance of chromate and salinity. This strain too exhibited the characteristics of multiple drug resistance (MDR) against several anti-microbial agents. Since the tannery discharges have huge population of harmful, antibiotic resistant strains, their discharge in water reservoirs and frequently in open environment should be processed prior to its release.
