The novel, Gram-stain-positive, ovoid, lactic acid bacterial isolates LMG 27205, LMG 27206, LMG 27207(T) and MRI-F 18 were obtained from throat samples of healthy humans. 16S rRNA gene sequence analyses indicated that these isolates belong to the genus Streptococcus, specifically the Streptococcus mitis group, with Streptococcus australis and Streptococcus mitis as the nearest neighbours (99.45...

This article discusses Streptococcus salivarius meningitis in a 39-year old woman. She was admitted to the hospital for general fatigue, headache, and fever. Cerebrospinal fluid analysis revealed leukocytosis and cultures were positive for Streptococcus salivarius. Streptococcus salivarius meningitis is rare and has been documented to be associated with procedures involving the spinal column su...

OBJECTIVES Ciprofloxacin is the most frequently used member of the fluoroquinolones during initial eradication therapy of Pseudomonas aeruginosa, as well as during acute pulmonary exacerbations. However, its long-term effect on the susceptibility of the commensal flora within the cystic fibrosis (CF) airways has not yet been examined. The aim of this study was therefore to examine the consequen...

Mastitis, a severe infectious disease among dairy cattle, is still a challenge for livestock treatment due to the increased infections by antibiotic resistant strains. Antimicrobial peptides could be the alternate for treating such drug resistant strains. In the present study, the whey proteins extracted from buffalo milk was subjected to enzymatic hydrolysis using trypsin, chymotrypsin, pepsin...

background and objectives:   many surface proteins are implicated in nasopharyngeal colonization and pathogenesis of streptococcus pneumoniae . some of these factors are candidate antigens for protein based vaccines. new vaccine designs focus on the surface proteins (e. g., pspa and pspc ) and also cytolysin, and pneumolysin. in this study, 3 key virulence genes, lyta , pspc , and rrga , which ...

conclusions the results of the present study indicate that brazilian propolis demonstrated in vitro anti-microbial efficacy against s. mutans and c. albicans. results the antimicrobial efficacy of hexidine against s. mutans and e. coli was higher compared to that of c. albicans. the brazilian propolis (p) mr showed antimicrobial action against s. mutans and c. albicans. the antimicrobial effica...

streptococcus pyogenes is one of the most important causes of bacterial pharyngitis. asymptomatic carriage of this organism especially among schoolchildren is a common issue. study of the prevalence and antimicrobial susceptibility pattern of the flora strains, as clinical indicators, are useful for treatment of streptococcal infections. the aim of this study was to determine the prevalence and...

normal 0 false false false en-us x-none ar-sa background : the beneficial effects of lactobacillus species have been reported but the role of these species including lactobacillus casei (l.casei) on oral health is not well documented. the purpose of this study was to evaluate the effects of conventional or probiotic cheese containing l.casei on salivary streptococcus mutans (sm) and lactobacill...

results the results of this study showed some s. pneumoniae serotypes were found in both sexes and some only in one sex invasive infections. for example, serotypes 10, 14, 18 and 22 were only in female patients with infections. conclusions the analysis of the results had suggested that serotypes 6 from lung and 19 from eye are the most abundant bacterial strains isolated from patients. the dise...
