Prevalence and Antimicrobial Resistance of Thermophilic Campylobacter Isolated from Chicken in Côte d’Ivoire

Abstract EN

Thermophilic Campylobacters are major causes of gastroenteritis in human.

The main risk factor of infection is consumption of contaminated or by cross-contaminated poultry meat.

In Côte d’Ivoire, gastroenteritis is usually observed but no case of human campylobacteriosis has been formally reported to date.

The aims of this study were to determine prevalence and antimicrobial resistance of Campylobacter jejuni and Campylobacter coli isolated from chickens ceaca in commercial slaughter in Abidjan.

Between May and November 2009, one hundred and nineteen (119) chicken caeca samples were collected and analyzed by passive filtration method followed by molecular identification (PCR).

From these 119 samples, 76 (63.8%) were positive to Campylobacter tests.

Among the positive colonies, 51.3% were C.

jejuni and 48.7% were C.

coli.

Of the 39 C.

jejuni isolates, 79.5%, 38.5%, 17.9%, 10.3%, and 7.7% were, respectively, resistant, to nalidixic acid, ciprofloxacin, amoxicillin, erythromycin, and gentamicin.

Among the 37 isolates of C.

coli, 78.4%, 43.2%, 13.5%, 8.1%, and 0% were resistant, respectively, to the same antibiotics.

In conclusion, we reported in this study the presence of high Campylobacter contamination of the studied chickens.

Molecular identification of the bacteria was performed and determination of high resistance to antimicrobials of the fluoroquinolone family was revealed.
