Present work is focused on the antagonistic potential of Alcaligenes strains isolated from cow dung against certain human pathogens. Seven bacterial strains were isolated from cow dung sample by serial dilution method. Based on morphological and biochemical investigations isolate, KD109 and KD110 were probably identified as Alcaligenes fecalis and Alcaligenes latus and screened for their antagonistic activity against 14 test organisms using cross-streak method. Both the isolates Alcaligenes fecalis and Alcaligenes latus demonstrated broad-spectrum antimicrobial activity against test organisms with maximum inhibition (10 mm) showed by KD109 against Salmonella typhi (MTCC 3216). The study indicates the potential of Alcaligenes spp. in the control of certain human pathogens.
