Distributions of Bacillus cereus, Pseudomonas, Enterococcus, and coliforms Isolated from Agricultural Products

Abstract

A survey was conducted on the bacterial contamination levels from 128 agricultural products, and identified 31 coliforms, 34 Bacillus spp., 35 Pseudomonas spp., and 3 Enterococcus spp.. Antibiotic susceptibility testing of eight Escherichia coli (E. coli) isolates, thirteen Bacillus cereus (B. cereus) isolates and seven Pseudomonas aeruginosa (P. aeruginosa) reveled that none of the E. coli isolates shows multidrug resistance pattern. However, one B. cereus isolate was resistant to Amoxicillin/clavulanic acid + Ampicillin/sulbactam + Cephaloxin, and twelve B. cereus isolates were resistant to Amoxicillin/clavulanic acid + Ampicillin/sulbactam + Cephaloxin + Tetracycline. The data from the current study points out that many agricultural products contain multidrug resistant bacteria, and it can be suggested for the need of proper guidelines and special management on the use of antibiotics in agricultural products.
