What kills streptococcus pneumoniae?
Pneumococcal pneumonia caused by organisms that are susceptible or intermediately resistant to penicillin responds to treatment with penicillin, one million units intravenously every 4 hours, ampicillin, 1g every 6 hours, or ceftriaxone, 1g every 24 hours. Ease of administration favors the use of ceftriaxone.
What kind of enzyme is alanine Racemase?
Alanine racemase (Alr) is a bacterial enzyme that catalyses the conversion of L-alanine to D-alanine (D-Ala)1. This function is critical for the growth of bacteria due to their need for D-alanine, an essential component in the biosynthesis of cell wall peptidoglycan in both gram-positive and gram-negative bacteria2.

What is the best antibiotic for Streptococcus pneumoniae?
Penicillin and its derivatives are inexpensive effective antibiotics for treating pneumococcal infections when they are used against susceptible isolates. Penicillins can be administered orally or parenterally and work by inhibiting cell wall synthesis.
What antibiotics are used to treat Streptococcus?
Doctors most often prescribe penicillin or amoxicillin (Amoxil) to treat strep throat. They are the top choices because they’re safer, inexpensive, and they work well on strep bacteria.
What does alanine Racemase do?
The D-alanine produced by alanine racemase is used for peptidoglycan biosynthesis. Peptidoglycan is found in the cell walls of all bacteria, including many which are harmful to humans.
What does Racemase mean?
Racemase definition (biochemistry) Any enzyme that catalyzes the stereochemical inversion of the configuration about an asymmetric carbon atom in a substrate having only one center of asymmetry. noun.
What is the difference between pneumonia and Streptococcus pneumoniae?
Pneumococcal disease is caused by bacteria called Streptococcus pneumoniae (pneumococcus). People with pneumococcal disease can spread the bacteria to others when they cough or sneeze. Symptoms of pneumococcal infection depend on the part of the body affected.
What is the drug of choice for Streptococcus pneumoniae?
Penicillins can be administered orally or parenterally and work by inhibiting cell wall synthesis. Penicillin G is the parenteral drug of choice for susceptible S pneumoniae infections, and other parenteral beta-lactams do not provide additional or improved coverage (nor do beta-lactamase inhibitor combinations).
What antibiotic kills Streptococcus?
Which antibiotic is more effective against Streptococcus pyogenes?
To date, S pyogenes has remained universally susceptible to penicillin. Therefore, penicillin remains the first-line drug of choice for pharyngeal infections, as well as for complicated or invasive infections.
