A study of the resistance patterns of 248 staphylococcal isolates from milk and milk products to eight antimicrobial agents using the disc method showed that 80 (32.3 %) were resistant to sulphafurazole, 75 (30.2 %) to penicillin G, 63 (25.4 %) to ampicillin, 23 (9.3 %) to cloxacillin, 19 (7.7 %) to tetracycline, 17 (6.9%) to streptomycin, 14 (5.6%) to erythromycin and 12 (4.8%) to chloramphenicol. One hundred and sixteen (46.8 %) of the 248 staphylococcal isolates were sensitive to all the agents tested. A significant percentage (P < 0.05) of the isolates from raw milk were resistant to erythromycin, sulphafurazole, cloxacillin, penicillin G and streptomycin compared to isolates from fermented milk. The minimum inhibitory concentrations (MIC) as determined by the tube method for isolates resistant by the disc method, were ≥ 16 μg for ampicillin in 5 (11.9 %) isolates; ≥ 40 μg for cloxacillin, 9 (36.0%) and ≥ 12 international units for penicillin G amongst 12 (22.2%) isolates. MIC values of ≥ 40 μg were recorded for 9 (90.0%), 9 (69.2%), 8 (73.7%) and 7 (70.0%) isolates to chloramphenicol, streptomycin, erythromycin and tetracycline respectively. The relatively high level of resistance to antimicrobial agents is a reflection of misuse or abuse of these agents in the environment. [ABSTRACT FROM AUTHOR] |
