Bactrim, a combination of sulfamethoxazole and trimethoprim, effectively targets a range of bacteria. Its spectrum isn’t as broad as some antibiotics, but it’s still useful against many common infections.
Gram-positive bacteria susceptible to Bactrim include:
- Staphylococcus aureus (certain strains, methicillin-sensitive) Streptococcus pneumoniae (certain strains) Streptococcus pyogenes Enterococcus faecalis (certain strains)
Gram-negative coverage is more limited:
- Escherichia coli (certain strains) Haemophilus influenzae (certain strains) Klebsiella pneumoniae (certain strains) Proteus mirabilis
Resistance to Bactrim is increasing, so culture and sensitivity testing is vital to ensure appropriate treatment. Always consult a doctor before using antibiotics. This information provides general guidance, not medical advice. A healthcare professional can determine the best antibiotic for your specific infection.
Accurate diagnosis is critical for effective treatment. Dosage and treatment duration depend on the infection’s severity. Side effects can occur; discuss any concerns with your physician.
