Antimicrobial susceptibility of thermophilic Campylobacter spp., isolated from environmental samples, to heavy metals and detergents was evaluated in the present study. The antimicrobial susceptibility of thermophilic Campylobacter spp. viz., Camp. jejuni, Camp. coli and Camp. lari against heavy metals and detergents in term of minimal inhibitory concentration was assessed by E- test. The result obtained indicated that most of the heavy metals and detergents have an antimicrobial effect on the thermophilic Campylobacter spp. isolates, but minimal inhibitory concentrations of them were not similar. In general, the most Campylobacter strains were resistant to high concentration of molybdenum and the detergent Tween 80, while were sensitive to cadmium and cetrimide at less concentration. To interpret, it could be noted that flow of industrial sewage including different heavy metals and detergents into the environment reduces the population of thermophilic Campylobacter. Therefore, type of samples and sampling sites affect the isolation rate of thermophilic Campylobacter from environment.

Abstract


Antimicrobial susceptibility of thermophilic Campylobacter spp., isolated from environmental samples, to heavy metals and detergents was evaluated in the present study. The antimicrobial susceptibility of thermophilic Campylobacter spp. viz., Camp. jejuni, Camp. coli and Camp. lari against heavy metals and detergents in term of minimal inhibitory concentration was assessed by E- test. The result obtained indicated that most of the heavy metals and detergents have an antimicrobial effect on the thermophilic Campylobacter spp. isolates, but minimal inhibitory concentrations of them were not similar. In general, the most Campylobacter strains were resistant to high concentration of molybdenum and the detergent Tween 80, while were sensitive to cadmium and cetrimide at less concentration. To interpret, it could be noted that flow of industrial sewage including different heavy metals and detergents into the environment reduces the population of thermophilic Campylobacter. Therefore, type of samples and sampling sites affect the isolation rate of thermophilic Campylobacter from environment.
