Erysipelas is an acute dermo-hypodermic (non-necrotizing) infection of bacterial origin, mainly group A beta-hemolytic streptococcus. The lower limbs are affected in more than 80% cases and the risk factors identified skin barrier breakdown, lymphedema obesity. Diagnosis clinical based on association inflammatory plaque with fever, lymphangitis, lymphadenopathy leukocytosis. Bacteriology genera...

Macaca mulatta on a normal diet proved to be resistant on intranasal inoculation with Streptococcus hemolyticus, group C. More than half of the monkeys maintained for various periods on a modified dietary regimen deficient in vitamin B became more or less anemic. All developed a granulopenic leucopenia during which many developed spontaneous infections, and all were extremely susceptible on int...

Microbial infection of the amniotic fluid is a significant cause of fetal injury, preterm birth, and newborn infections. Group B Streptococcus (GBS) is an important human bacterial pathogen associated with preterm birth, fetal injury, and neonatal mortality. Although GBS has been isolated from amniotic fluid of women in preterm labor, mechanisms of in utero infection remain unknown. Previous st...

Pneumolysin is an important virulence factor of the human pathogen Streptococcus pneumoniae. Sequence analysis of the ply gene from 121 clinical isolates of S. pneumoniae uncovered a number of alleles. Twenty-two strains were chosen for further analysis, and 14 protein alleles were discovered. Five of these had been reported previously, and the remaining 9 were novel. Cell lysates were used to ...

In a previous paper (1) it was reported that certain non-hemolytic streptococci from the human throat are capable of synthesizing large amounts of a carbohydrate from sucrose and raffinose. These organisms seem to be similar to those studied by Oerskov and Poulsen (2). When grown on the surface of agar containing 5 per cent sucrose or raffinose, large mucoid colonies are produced which are abou...

1. The concentrations of penicillin G which (a) reduced the net rate of multiplication, (b) exerted a net bactericidal effect, and (c) killed the organisms at a maximal rate, have been defined for a total of 41 strains of alpha- and beta-hemolytic streptococci, Staphylococcus aureus and Staphylococcus albus, Diplococcus pneumoniae, and the Reiter treponoma. 2. The concentration which killed the...

Introduction Group B streptococcus is the main reason of neonatal infection in developed countries and causes a widespread clinical indications. In developing countries such as Iran, its rate of appearance is not determined. With regard to colonization and the relative high epithelia of group B streptococcus, it is likely that the incidence of group B streptococcus in neonatal sepsis is so high...

Background: The gram-positive, beta-hemolytic, and chain-forming Group B Streptococcus (GBS), commonly known as agalactiae, may asymptomatically invade the human gastrointestinal vaginal tracts. However, GBS become very invasive pathogenic to mother baby during pregnancy, having negative effects. Study Aim: This study aims investigate pregnancy outcomes of women who tested positive for genitour...
