Protozoal infection of human beings or animals is treated with a divalent
metal salt of bacitracin. Some infectious agents sensitive to such
treatment include human pathogens such as Entamoeba histolytica,
Trichomonas vaginilis, Gtardia lamblia, Cryptosporidium parvum, and animal
pathogens such as Tritrichomonas foetus and Tritrichomonas gallinae.
