The article presents the results of a clinical and bacteriological assessment pharmacological efficacy 1,3-diethylbenzimidazolium triiodide in chronic compensated tonsillopharyngitis. As result 10-day course treatment, an improvement status patients was achieved, as well significant positive effect on composition pharyngeal microbiocenosis. In particular, content Staphylococcus aureus, β-hemoly...

objective(s): streptococcus pyogenes produces extracellular hyaluronidase enzyme. this enzyme is directly associated with the spread of the organism during infection. the objective of the present study was to clone and express the nucleotide sequence of the enzyme which is involved in hyaluronidase enzymatic activity. materials and methods: the enzymatic region of hyaluronidase gene was detecte...

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...

BACKGROUND Acute rheumatic fever is a major cause of heart disease in Aboriginal Australians. The epidemiology differs from that observed in regions with temperate climates; streptococcal pharyngitis is reportedly rare, and pyoderma is highly prevalent. A link between pyoderma and acute rheumatic fever has been proposed but is yet to be proven. Group C beta-hemolytic streptococci and group G be...

Although the bad prognostic value of presence hemolytic streptococci in genital secretions women labor and delivery has been disputed on different sides, yet numerous studies have convinced author that hemolysis this case is indeed signum mali ominis, applies not only to streptococci, but also other representatives microbial flora female canal.

this study was undertaken to determine the antibiotic sensitivity of 686 strains of hemolytic streptococci isolated at the school of public health, divi­sion of streptococcal studies, to five antibiotics in vitro. all of the strains were sensitive to penicillin, erythromycin, chloramphenicol and ampicillin. 27 (4%) of the strains, were resistant to tetracyclin. the clinical implications of this...

a total of 711 beta-hemolytic streptococci were isolated from throat cultures of patients during 1970-73. these strains were grouped in parallel by the precipitin and bacitracin paper disk method. the former method was estab­lished as the standard by which the bacitracin technique was compared. the difference in results was about 5.67%. the greatest error (5.4%) was seen with non-group a strain...

1. Hemolytic streptococcus has been found in 100 per cent of the throats of patients with scarlet fever during the 1st week of the disease. 2. The average length of time that these organisms are present in the throat varies from 10 to 20 days. 3. No morphological or cultural characteristics peculiar to the hemolytic streptococcus from scarlet fever can be demonstrated. 4. Ten immune sera have b...

The Directigen Group A Strep Test (DGAST), a new rapid method of detecting group A beta-hemolytic streptococci directly from throat swabs, was compared with a traditional culture technique for the detection of group A beta-hemolytic streptococci. Five hundred oropharyngeal swabs from pediatric and adult patients were cultured and then processed by using the DGAST. Of the 144 specimens positive ...
