Two patients developed neurosyphilis after treatment of latent syphilis with intramuscular benzathine penicillin. The cases confirm recent investigations that show that neither benzathine penicillin nor procaine penicillin in the standard doses results in treponemicidal concentrations of penicillin in cerebrospinal fluid. Neurosyphilis can be treated effectively by intravenous benzylpenicillin ...

R. Valluzzi, and J.-L. Guéant. What is the problem and what is known about it so far? Allergic reactions to the antibiotic penicillin are common. Meropenem is an antibiotic that fights many of the same infections as penicillin. Meropenem may be an option for patients who are allergic to penicillin. However, meropenem and penicillins have similar chemical structures; therefore, doctors often avo...

Chlamydia pecorum causes asymptomatic infection and pathology in ruminants, pigs, and koalas. We characterized the antichlamydial effect of the beta lactam penicillin G on Chlamydia pecorum strain 1710S (porcine abortion isolate). Penicillin-exposed and mock-exposed infected host cells showed equivalent inclusions numbers. Penicillin-exposed inclusions contained aberrant bacterial forms and exh...

BACKGROUND Ertapenem is a novel carbapenem with activity against both penicillin-susceptible (MIC < or = 0.06 mg/L) and penicillin-non-susceptible (MIC > or = 0.12 mg/L) Streptococcus pneumoniae. This study assessed the pharmacodynamic activity of ertapenem against penicillin-susceptible and penicillin-non-susceptible S. pneumoniae using an in vitro pharmacodynamic model. METHODS Fifteen S. p...
