5-8.0 mg/L) within the MIC ranges assayed (Table 2). The strains were highly susceptible to ampicillin (0.5-2.0 mg/L), chloramphenicol (2–4 mg/L), clindamycin (0.5-2.0 mg/L) and erythromycin (0.5-1.0 mg/L).

The chloramphenicol MIC value (4 mg/L) obtained for Lb. plantarum, Leuc. pseudomesenteroides, Lb. ghanensis and Lb. fermentum was one-fold higher than the MIC value obtained for Ped. acidilactici, Ped. pentosaceus and Weissella species. Lb. plantarum, Lb. salivarius, W. confusa (except strain SK9-5) and Lb. fermentum strains were susceptible to tetracycline. However, Pediococcus strains and the Lb. ghanensis strain were resistant to tetracycline since the MIC values (16–32 mg/L) obtained were higher than the recommended breakpoint value (8 mg/L). The resistance profile of the strains to gentamicin varies at both species and strains level. Leuc. pseudomesenteroides,

Lb. ghanensis and Ped. acidilactici check details strains were resistant to 64 mg/L gentamicin. However, the majority (4 out of 5) of W. confusa strains have MIC value of 16 mg/L selleck inhibitor whereas the MIC value obtained for most (7 strains) of Lb. plantarum strains was 32 mg/L.
