An antibiotic isolated from B. subtilis, active against Gram-positive bacteria and Neisserieae. Used to differentiate Group A streptococci (which are sensitive to it) from all other groups, which are not.
An antibiotic produced by certain strains of bacteria and effective against a number of microorganisms. It is usually applied externally, to treat infections of the skin, eyes, or nose, but can be given by mouth as an intestinal antiseptic or by injection. The principal toxic effect is on the kidneys.
An antibiotic which is not absorbed if taken by mouth, but is valuable as an ointment in conjunction with neomycin or polymyxin.
An antibiotic obtained from a strain of Bacillus subtilis. Its antibacterial actions are similar to those of penicillin. It treats gram positive cocci and bacilli and some gram-negative organisms. Because bacitracin is toxic when used parenterally, it is usually applied topically in ointment form.
Bacitracin, a specific type of antibiotic medication, is employed in conjunction with other drugs to address infections affecting the eyes and skin. Typically, bacitracin is administered topically in the form of an external skin preparation or as eye drops for ocular application.
