Cefixime is effective against several bacteria, including Escherichia coli, Proteus mirabilis, Haemophilus influenzae, Moraxella catarrhalis, and Streptococcus pyogenes.
Here's a more detailed breakdown:
Cefixime is a cephalosporin antibiotic used to treat various bacterial infections. It works by interfering with the bacteria's ability to build their cell walls, ultimately leading to bacterial cell death. The specific bacteria susceptible to cefixime include, but may not be limited to:
-
Gram-Negative Bacteria:
- Escherichia coli (E. coli): A common cause of urinary tract infections (UTIs).
- Proteus mirabilis: Another bacterium frequently implicated in UTIs.
- Haemophilus influenzae: A cause of otitis media (middle ear infection) and respiratory infections.
- Moraxella catarrhalis: Often associated with otitis media and respiratory infections.
-
Gram-Positive Bacteria:
- Streptococcus pyogenes: The causative agent of strep throat (pharyngitis) and tonsillitis.
Important Considerations:
- Antibiotic Resistance: The effectiveness of cefixime can be affected by antibiotic resistance. Some strains of bacteria may be resistant to cefixime, rendering the antibiotic ineffective.
- Specific Infections: Cefixime is commonly prescribed for specific infections like uncomplicated UTIs, otitis media, pharyngitis, and tonsillitis, when caused by susceptible bacteria.
- Prescription Required: Cefixime, like all antibiotics, requires a prescription from a healthcare professional. Self-treating with antibiotics can contribute to antibiotic resistance.
- Complete the Course: It's crucial to complete the full course of antibiotics as prescribed, even if symptoms improve, to ensure that the infection is completely eradicated and to minimize the risk of antibiotic resistance.
In summary, cefixime is effective against a range of bacteria, including E. coli, P. mirabilis, H. influenzae, M. catarrhalis, and S. pyogenes, making it a valuable tool in treating various bacterial infections when the responsible bacteria are susceptible.
