Antibiotics are often prescribed to treat infections caused by group B Streptococcus; however, inappropriate use of antibiotics can develop resistance. Because this, the research was carried out with aim evaluating in vitro effect hydroalcoholic extract Caesalpinia spinosa (Molina) Kuntze known as Taya or Tara on viability β-hemolytic streptococci; an experimental investigation increasing stimu...

Dental caries-associated oral streptococci are called the mutans streptococci, with Streptococcus mutans and Streptococcus sobrinus being the most prevalent caries-associated organisms in humans. Strains of the mutans streptococci are highly conserved within not only mothers and their children but also racial groups, suggesting vertical transmission of this organism within human populations. It...

The optimal incubation conditions for isolation of group A streptococci from throat cultures are controversial. Therefore, we compared the effects of aerobic and anaerobic incubations after 24 and 48 h on the recovery of group A streptococci. Throat swabs submitted to the clinical laboratory were inoculated onto duplicate 5% sheep blood agar plates, incubated aerobically or anaerobically (GasPa...

I t has been known for many years t ha t some strains of Escherichia coli, Bacillus megaterium, and Group D streptococci secrete substances called colicines, or bacteriocines, which inhibi t the growth of o ther strains of closely related microorganisms (1-6). In 1949 Sherwood and his coworkers (7) reported observations on the inhibitory action of certain strains of be ta hemolyt ic streptococc...

A microbiological diagnosis of pharyngitis is essential for confirmation of Group A Streptococci. Macrolide is given to those patients who are allergic to Penicillin. Various rates of Macrolide resistance of Streptococcus pyogenes are reported worldwide. A total of 400 children was included in the study. All samples were processed by standard Microbiological protocol. Antibiotic susceptibility ...

The objective of this study was to investigate the ability of biofilm formation among mutans and non mutans oral streptococci and to determine the effect of Lactobacillus acidophilus DSM 20079 as a probiotic strain on the adhesion of selected streptococcal strains on the surfaces. The sample comprised 40 isolates of oral streptococci from dental plaque and caries of volunteer persons. Streptoco...

1. Minute beta hemolytic streptococci were found to occur from one-third to one-half as frequently in normal individuals as do ordinary beta hemolytic streptococci. 2. They were rarely isolated from the rhinopharynges of individuals suffering from chronic disease. 3. In acute respiratory tract infection other than that due to the ordinary beta hemolytic streptococcus the incidence of minute str...
