“…The diameter and length of the inhibition zone of each B. cereus isolate were measured with a vernier caliper to explain antibiotic sensitivity [43], and the results were interpreted following the guidelines provided by the CLSI document M100, 31st edition [42,44]. To evaluate the efficacy of the antimicrobial susceptibility testing process [45], Escherichia coli ATCC 25922 and Staphy-lococcus aureus ATCC 29213 were used as control strains, and 73 strains of B. cereus were divided into sensitive (S), intermediary (I), and resistant (R).…”

Bacillus cereus is a common pathogen causing foodborne diseases, secreting and producing a large number of toxins that can cause a variety of diseases and pose many threats to human health. In this study, 73 strains of Bacillus cereus were isolated and identified from six types of foods from seven different cities in a province, and the antibiotic-resistant phenotype was detected by using the Bauer–Kirby method. Results showed that the 73 isolates were completely sensitive to gentamicin and 100% resistant to chloramphenicol, in addition to which all strains showed varying degrees of resistance to 13 other common antibiotics, and a large number of strains resistant to multiple antibiotics were found. A bioinformatic analysis of the expression of resistance genes in Bacillus cereus showed three classes of antibiotic-resistant genes, which were three of the six classes of antibiotics identified according to the resistance phenotype. The presence of other classes of antibiotic-resistant genes was identified from genome-wide information. Antibiotic-resistant phenotypes were analyzed for correlations with genotype, and remarkable differences were found among the phenotypes. The spread of antibiotic-resistant strains is a serious public health problem that requires the long-term monitoring of antimicrobial resistance in Bacillus cereus, and the present study provides important information for monitoring antibiotic resistance in bacteria from different types of food.
