the aim of the present research was focused on the antibacterial, preliminary phytochemical and pharmacognostical properties of vicoa indica (l.)dc. via in vitro approach. the aqueous and organic solvent (hexane, chloroform and methanol) extracts from the leaves of vicoa indica (asteraceae) were tested against escherichia coli, klebsiella pneumoniae, salmonella typhi, vibrio parahaemolyticus, v...

background:pneumonia and respiratory tract infections, is associated with high mortality and complications in humans. current antibiotics are used to treat this infectious disease, but may lead to many problems such as unwanted side effects and resistance to antibiotics. this study investigated the antibacterial activity of the hydro alcoholic extracts of the native medicinal plants peganum har...

Background: Klebsiella pneumoniae is one of the most important bacteria that cause nosocomial infections. This opportunistic pathogen has a high potential for antibiotic resistance and can generate a thick layer of biofilm. Nowadays, antibiotic resistant strains are emerging and widely spreading worldwide. Thus, it is necessary to combat drug-resistant strains through the use of novel drugs (su...

conclusions our results indicated that the dissemination of pi-1 was widespread in s. pneumoniae isolates, although no pi-2 isolates were detected. furthermore, the frequency of rlra and rrgc of clinical isolates was significantly more than that of normal flora isolates. results the results confirmed the presence of rlra and rrgc genes in both clinical (n = 39) and normal flora (n = 26) isolate...

conclusions: with respect to the obtained results and regarding to the daily increase of the resistant microbial strains to the commercial antibiotics, it can be concluded that these extracts can be proper candidates of antibacterial substance against pathogenic bacterial species especially s. aureus, e. coli, k. pneumoniae and s. epidermidis. results: the extract of c. fistula was effective ag...

background: streptococcus pneumoniae is a major cause of childhood morbidity and mortality worldwide . several studies have explored the nasopharyngeal carriage of s. pneumonia in iran. this meta-analysis is aimed at exploring the overall prevalence of nasopharyngeal carriage of s. pneumoniae among healthy children and its resistance to antibiotics. method : we have systematically reviewed publ...

objective(s): macrolide resistant streptococcus pneumoniae pose an emerging problem globally. the aim of this study was to investigate the prevalence of ermb and mefa genes (macrolide resistant genes) by polymerase chain reaction (pcr) method and to detect drug resistance patterns of s. pneumoniae isolated from clinical samples to macrolides and other antibiotic agents by e-test method. materia...
