Antibiotic resistance of isolated Salmonella gallinarum strains in modern poultry farming in suburban areas in Mali

Abstract

The objective of the study, conducted from August 2014 to December 2015, was to test the antibiotic resistance of 52 Salmonella gallinarum isolates obtained from modern poultry farms located in suburban areas of Bamako District (n = 27), and of Segou (n = 16) and Sikasso (n = 9) cities. The average resistance rates obtained were 98.08% to erythromycin, 94.23% to colistin, 90.38% to streptomycin, 67.31% to kanamycin, 65.38% to flumequine, 63.46% to doxycycline, 59.61% to tetracycline and 21.15% to gentamicin. All Salmonella isolates from Bamako District farms were resistant to tetracycline, doxycycline and erythromycin. Similarly, all isolates from Sikasso area farms showed resistance to erythromycin, tetracycline, colistine and streptomycin. The results showed a development of resistance of most isolated salmonella strains to the majority of common antibiotics, and to a lesser extent to gentamicin.
