streptococcuscus beta hemolytic group a is the most important pathogen causing which may lead to purulent and non purulent angina. rheumatic fever is the most important complication that is the cause of 30% to 40% of cardiac disease and disablement. this study was performed to evaluate prevalence of streptococcuscus beta hemolytic group a and estimate role of clinical findings in children with ...

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...

Aim: Streptococcus pyogenes (Group A Beta-hemolytic streptococci, GABHS) is one of the important bacterial pathogens in clinical microbiology. It often causes upper respiratory tract infections such as tonsillitis, pharyngitis, and laryngitis. also leads to complications acute rheumatic fever post-streptococcal glomerulonephritis. Early diagnosis treatment these will prevent suppurative non-sup...

While group C beta hemolytic streptococcal infections are uncommon in humans, group C beta hemolytic streptococcal pneumonia is exceedingly rare. To the best of our knowledge, only 2 cases of necrotizing pneumonia caused by group C beta hemolytic streptococcus have been reported in the past. Thus, we are reporting a rare case of necrotizing group C beta hemolytic streptococcal pneumonia in a y...

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...

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 ...

OBJECTIVE If pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections is a unique clinical entity, we hypothesized that children meeting diagnostic criteria would have more clinical exacerbations temporally linked to bona fide group A beta-hemolytic streptococcus infection than matched control subjects (chronic tic and/or obsessive-compulsive disorder with no kno...

AIM To study the influence of enterococci on human sperm membrane in vitro. METHODS Ejaculated human sperm were artificially infected with beta-hemolytic or non-beta-hemolytic enterococci at the bacteria: sperm ratio of 50:1 at 37 degrees . Sperm membrane integrity was examined after incubation for 1, 3 and 5 h by hypoosmotic swelling (HOS) test and electron microscopy. RESULTS Sperm infect...
