Ampicillin/sulbactam is also used when the cause of an infection is not known (empiric therapy), such as intra-abdominal infections, skin infections, pneumonia, and gynecologic infections. It is active against a wide range of bacterial groups, including Staphylococcus aureus , Enterobacteriaceae , and anaerobic bacteria .
Ampicillin is used to treat infections by many gram-positive and gram-negative bacteria. It was the first "broad spectrum" penicillin with activity against gram-positive bacteria, including Streptococcus pneumoniae , Streptococcus pyogenes , some isolates of Staphylococcus aureus (but not penicillin-resistant or methicillin-resistant strains ...
Wide range of infections; penicillin used for streptococcal infections, syphilis, and Lyme disease: Gastrointestinal upset and diarrhea; Allergy with serious anaphylactic reactions; Brain and kidney damage (rare) Same mode of action as other beta-lactam antibiotics: disrupt the synthesis of the peptidoglycan layer of bacterial cell walls ...
Strep rates are still higher than usual, a challenge that has been compounded by an antibiotic shortage. But doctors are optimistic the trend will abate soon.
β-Lactam antibiotics are indicated for the prevention and treatment of bacterial infections caused by susceptible organisms. At first, β-lactam antibiotics were mainly active only against gram-positive bacteria, yet the recent development of broad-spectrum β-lactam antibiotics active against various gram-negative organisms has increased their usefulness.
Infections typically begin in the throat or skin. The most striking sign is a strawberry-like rash. Examples of mild S. pyogenes infections include pharyngitis (strep throat) and localized skin infection . Erysipelas and cellulitis are characterized by multiplication and lateral spread of S. pyogenes in deep layers of the skin.
Antibiotics are used to treat or prevent bacterial infections, [34] and sometimes protozoan infections. (Metronidazole is effective against a number of parasitic diseases). When an infection is suspected of being responsible for an illness but the responsible pathogen has not been identified, an empiric therapy is adopted. [35]
