In the present study, the probiotic potential of Lactobacillus isolates selected from fecal samples of farmyard chickens and ducks was scientifically validated for their use as alternatives to antibiotics in poultry. A total of 129 Lactobacillus isolates were characterized of which four produced inhibitory substances with antimicrobial activities. They were further identified on the basis of their carbohydrate fermentation profile and High-Resolution Melting analysis as Lactobacillus paracasei MW-37CGZ, Lactobacillus paracasei MW-38CGZ, Lactobacillus plantarum MW-48CGZ and Lactobacillus plantarum MW-18CGZ. The obtained results revealed that L. plantarum MW-18CGZ and L. paracasei MW-37CGZ showed strong antagonistic activities against human (nine) and zoonotic pathogens (eleven). The antimicrobial substance produced by L. plantarum MW-18CGZ was found to be proteinaceous, thus indicating that this substance may belong to a group of potent antimicrobial peptides produced by some microorganisms including lactic acid bacteria (LAB). Both viable and non-viable cells of the four isolates demonstrated good hydrophobicity in xylene with L. plantarum MW-48CGZ exhibiting higher hydrophobicity than other isolates (77.64±5.18%). They were susceptible to chloramphenicol, clindamycin, ampicilin and erythromycin with Minimum Inhibitory Concentration (MIC) below cut-off values established by the European Food Safety Authority (EFSA). Among the four Lactobacillus, L. plantarum MW-18CGZ and L. paracasei MW-37CGZ displayed high autoaggregation and coaggregation towards pathogens and all isolates survived in low-pH, high bile salt concentrations and none exhibited virulent factors. According to the obtained results, L. plantarum MW-18CGZ and L. paracasei MW-37CGZ could be considered as future biotherapeutic substitutes for antibiotics to reduce antibiotic residues in food derived from poultry as well as the generation and spread of antibiotic resistance.
