Rifampin is a semisynthetic antibiotic derived from rifamycin B to produce rifampin (US and Canadian name), also known as rifampicin in Europe. Rifampin has a high activity against gram-positive bacteria (Staphylococcus spp.), Mycobacterium spp., Haemophilus spp., Neisseria spp., and Chlamydia spp. but more limited activity against the gram-negative bacteria because it penetrates the gram-positive organism cell wall more easily than the gram-negative organism cell wall. Rifampin is highly lipid soluble and has the charact

In veterinary medicine, rifampin has been used to treat susceptible gram-positive and intracellular bacteria, including Staphylococcus species (including methicillin-resistant strains); Streptococcus spp.; Rhodococcus equi; Corynebacterium pseudotuberculosis; and most strains of Bacteroides spp., Clostridium spp., Neisseria spp., and Listeria spp. Gram-negative organisms are not affected at typical doses. In small animals, it is occasionally used to treat staphylococcal infections, particularly methicillin-resistant strains. R
