Study Of The Antibiotic Resistance Profile Of Escherichia Coli And Salmonella Spp. Isolated From Cattle Dung At The Port-Bout Slaughterhouse Abidjan Ivory Coast

The overconsumption of antibiotics by livestock represents a productivity gain for the agri-food industry but the emergence and growing development of bacterial antimicrobial resistance is a global public health problem that is hurting the agri-food industry. This work aims to evaluate the use of antibiotics in farms and to determine the antibiotic resistance profile of strains of E. coli and Salmonella spp. isolated cattle dung at the abattoir of Port-Bout Abidjan Cte dIvoire. Studies have been conducted to identify and identify the desired bacteria. Then the sensitivity of the isolated bacterial strains to the antibiotics was determined by the standard method of diffusion on Mueller-Hinton agar medium. Samples 77 of bovine dung were collected and bacteriological analysis identified 23 strains of E. coli and 4 strains of Salmonella spp. used for the antimicrobial resistance test. Of the 77 cattle dung samples collected the results showed the presence of resistant E. coli in 23 or 29.86 isolates and 4 isolates or 5.19 of Salmonella spp. Of which 23 were E. coli strains tested. at 16 of the 21 antibiotics used a resistance level of 71.19 the 4 isolates of Salmonella spp. were mostly resistant to 4 antibiotics ie 19.04. The highest levels of E. coli resistance were observed with -lactams 100 with the exception of Cefoxitin Imipenem and 100 Tetracycline. For Salmonella spp. these levels were observed with Tetracycline 100 and Ciprofloxacin 50. The resistance phenotypes and the resistance rates observed on the isolates obtained at the Port-Bout abattoir encourage increased surveillance of the use of antibiotics in the cattle industry in Cte dIvoire. This study revealed the presence of Salmonella spp. and important strains of E. coli in bovine dung but mostly revealed the resistance of the strains to different antibiotics with high rates of resistance. Resistance having a considerable impact on the health of consumers causing many pathologies Urinary tract infections Typhoid fever Food toxi-infection.
