Streptococcus pneumonia is one of the most common pathogens in the humaun beings, specially in childhood. Knowing of it’s “Antibiotic resistance” is very important for antibiotic administration by medical persons. Between 1996-1997 nasopharyngeal culture has been done in 170 healthy child whom stayed in day care centers. Of 170, 51/8% (mean age=3.98years) were female and 48.2% (mean age=3.99ye...
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...
Resistance (intermediate and high) to penicillin among Streptococcus pneumoniae strains is an emerging problem worldwide. From 1995 to 1997, isolates of S. pneumoniae not susceptible to penicillin were seen with increasing frequency from blood, cerebrospinal fluid, pleural fluid, and middle ear fluid from pediatric patients at the Veterans General Hospital-Kaohsiung. To determine the prevalence...
Eight recent isolates of Neisseria gonorrhoeae with high-level non-beta-lactamase-mediated penicillin resistance were investigated. The penicillin-binding proteins of these strains were found to have reduced affinity for radiolabeled penicillin. Testing for known resistance genes showed that these were present in the resistant isolates. Genetic transformation was used to construct strains with ...
Plants used for traditional medicine contain a wide range of substances which can be used to treat various infectious diseases. Hence, antibacterial activities of ethanolic extracts of 19 plant species were studied against multi-drug resistant clinical isolates using agar well diffusion method. Extracts of Liquidambar orientalis, Vitis vinifera,?? ?????????????????????? ????????????????????,...
