the genus teucrium (germander) belongs to the family lamiaceae, within the subfamily ajugoideae .teucrium polium l. (labiatae) has long been recognized in folk medicine in the treatment of many pathophysiological implications, such as gastrointestinal disorders, inflammations, diabetes and rheumatism. in this study antimicrobial activity of two crude extracts obtained from teucrium polium l. wa...

Streptococcus pyogenes is the major bacterial pathogen responsible for acute pharyngitis in children. Oral penicillin is the drug of choice for streptococcal pharyngitis, while macrolides are an alternative option for patients allergic to penicillin. The frequent use of macrolides promotes the spread of erythromycin resistance (1-2), but reducing the use of these antibiotics has been correlated...

Pseudomonas aeruginosa and Streptococcus pyogenes are leading causes of medical device-associated infections. The capacity to establish and maintain these infections is thought to be associated with the ability to form surface-attached biofilms. In the present study, gallium nitrate was used to coat PVC plates and biofilm formation on the plates by Pseudomonas aeruginosa and Streptococcus pyoge...

Φm46.1 - Streptococcus pyogenes bacteriophage carrying mef(A) and tet(O), respectively, encoding resistance to macrolides (M phenotype) and tetracycline - is widespread in S. pyogenes but has not been reported outside this species. Φm46.1 is transferable in vitro among S. pyogenes isolates, but no information is available about its transferability to other Streptococcus species. We thus investi...

Salivaricin G32, a 2667 Da novel member of the SA-FF22 cluster of lantibiotics, has been purified and characterized from Streptococcus salivarius strain G32. The inhibitory peptide differs from the Streptococcus pyogenes-produced SA-FF22 in the absence of lysine in position 2. The salivaricin G32 locus was widely distributed in BLIS-producing S. salivarius, with 6 (23%) of 26 strains PCR-positi...

Aerobic respiration of Streptococcus pyogenes and pneumococcus Type 1 are strongly inhibited by KCN, NaN(3), and Na(2)S. The anaerobic glycolysis of glucose by pneumococcus is also inhibited by KCN and NaN(3). Streptococcus pyogenes, E. coli, pneumococcus Type 1, B. subtilis, B. proteus, and Staphylococcus aureus did not catalyze the oxygen uptake by p-phenylenediamine in the presence of added ...

INTRODUCTION Community-acquired meningitis is a monomicrobial infection caused by either viruses or bacteria in the vast majority of patients. We report here one exceptional case of a patient with mixed bacterial meningitis due to Streptococcus pneumoniae and Streptococcus pyogenes. CASE PRESENTATION We report the case of a 68-year-old immunocompromised Caucasian man suffering from otitis and...

background and objective: although there are reports in the literature on the antimicrobial effects of green tea, the effect of black tea, the most common beverage in iran, on growth of bacteria, such as streptococcus pyogenes, has not been studied extensively. this study was undertaken to determine the inhibitory effect of black tea on the growth of streptococcus pyogenes in vitro and compare ...
