Antioxidant activity and thermal stability of the chimeric peptide was determined. The results showed that cLFchimera had antioxidant activity (IC50 310 μ/mL) and its activity was not affected after 40 min of boiling. Finally, we evaluated the interaction of the peptide with LPS and DNA in bacteria using molecular dynamic simulation as two main intra and extra cellular targets for AMPs, respectively. Our in silico analysis showed that cLFchimera had strong affinity to both of these targets by positive charged residues after 50 ns molecular dynamic simulation. CONCLUSIONS Overall, the engineered food-grade L. lactis generated in the present study successfully expressed a secreted chimeric peptide with antimicrobial properties and could be considered as a promising bio-preservative in the food industry.BACKGROUND Over thousands of animal bite cases are reported annually worldwide and in Iran placing a large financial burden on the health and economy. The aim of this study was to evaluate the epidemiology of animal bite cases in Kermanshah, Iran through 2013-2017. METHODS In this cross-sectional study, 5618 animal bite cases in Kermanshah from 2013 to 2017 were studied. Data were analyzed using descriptive and inferential statistics. RESULTS In the study period, 5618 animal bite cases were found. The prevalence of animal bites was estimated between 42.55-45.66 per100000 populations during 2013-2017. An increasing significant trend was found for prevalence of animal bites (Average annual percent change [AAPC] + 4.9, P-trend less then  0.001) over a 5-years' time period. The mean age of the subjects was 32.7 ± 18.3 years. Of the studied subjects 76.3% were male, and 34% had non-governmental jobs. Dogs were found as the cause of animal bites in 72% of the
