Sulfamethazine is a sulfonamide that presents a broad spectrum of activity, including gram-positive and gram-negative bacteria, Chlamydia spp. and some protozoa. This drug has been reported to be highly efficacious in the treatment of pneumonias, diarrheas and coccidiosis in cattle, as commonly susceptible micro-organisms are Bacillus spp., Brucella spp., Listeria monocytogenes, Nocardia spp., Streptococcus spp., Escherichia coli, Chlamydia spp., Pneumocystis carinii, Cryptosporidium spp., and Toxoplasma spp. (Lindsay et al., 1996; Lindsay & Dubey, 1999; Oliveira et al., 2000; Spoo & Riviere, 2001). However, Leptospira spp. and Pseudomonas spp. are resistant (Prescott, 2000).
