Shigella

 

a genus of microorganisms of the family Enterobacteriaceae. It comprises different species of the causative agent of dysentery in monkeys and humans. They are gram-negative, nonmotile, nonspore-forming rods measuring 2–3 micrometers long and 0.6 micrometer wide. Aerobes and facultative anaerobes are distinguished. Shigellae form delicate semitransparent colonies on agar. They are subdivided into different types according to the colicins they secrete.

The BEF terpolymer and its metal complexes were screened for their antimicrobial activity by disc diffusion method [21] against six bacterial strains such as Shigella sonnei, Escherichia coli, Klebsiella species (NCIM 2719), Staphylococcus aureus (ATCC 25923), Bacillus subtilis (ATCC 6633), and Salmonella typhimurium (ATCC 23564) and six fungal strains such as Aspergillus flavus, Aspergillus niger, Penicillium species, Candida albicans, Cryptococcus neoformans, and Mucor species.
