Background: The SD Bioline Strep A Ultra (SD, Yongin, Korea) is a recently developed rapid antigen detection test (RADT) for diagnosing bacterial pharyngitis caused by Group A , We evaluated the performance of SD Bioline Strep A Ultra, using the number of colony forming units and color intensity.
Methods: Three throat swabs each were taken from 343 children with pharyngitis who visited pediatric clinics. We evaluated the performance of SD Bioline Strep A Ultra and compared its positive rate with the number of colony forming units, using the Fisher exact test. Read More

Streptococcus pyogenes is an important bacterial pathogen that colonizes the throat and skin of human beings and causes a wide variety of diseases ranging from mild infections like pharyngitis, tonsillitis and impetigo to severe invasive infections such streptococcal toxic shock syndrome, septicemia, and necrotizing fasciitis, and produces a wide variety of virulence factors. The aim of this study was to investigate the antibiotic resistance, virulence genes; [pyrogenic exotoxin genes (speA, C, G, H, I, J, K, L, M, smeZ and ssa), deoxyribonuclease genes (sdaB, spd3, sdc ve sdaD), protease genes (speB, spyCEP ve scpA) and inhibitor genes (mac and sic)] of S.pyogenes strains isolated from throat cultures of patients with symptomatic tonsillo-pharyngitis and typing by multiple locus variable number tandem repeat fingerprinting (MLVF) method.

Pharyngeal tonsillitis is one of the most common upper respiratory tract infections, and group A streptococcus is the most important bacterial pathogen causing it. While most patients experience tonsillitis only rarely, a subset of patients suffers from recurrent or chronic tonsillitis or pharyngitis. The predisposing factors for recurring or chronic forms of this disease are not yet fully understood, but genetic predisposition has been suggested. Read More

Acute rheumatic fever is caused by an autoimmune response to throat infection with Streptococcus pyogenes. Cardiac involvement during acute rheumatic fever can result in rheumatic heart disease, which can cause heart failure and premature mortality. Poverty and household overcrowding are associated with an increased prevalence of acute rheumatic fever and rheumatic heart disease, both of which remain a public health problem in many low-income countries.

The bacterial pathogen Group A (GAS) has been shown to induce a variety of human diseases ranging in severity from pharyngitis to toxic shock syndrome and necrotizing fasciitis. GAS produces a powerful peptide toxin known as Streptolysin S (SLS). Though long recognized as a potent cytolysin, recent evidence from our lab has shown that SLS-dependent cytotoxicity is mediated through activation of the pro-inflammatory mediators p38 MAPK and NFκB.

Streptococcus pyogenes is a human-specific and globally prominent bacterial pathogen that despite causing numerous human infections, this bacterium is normally found in an asymptomatic carrier state. This review provides an overview of both bacterial and human factors that likely play an important role in nasopharyngeal colonization and pharyngitis, as well as the development of acute rheumatic fever and rheumatic heart disease. Here we highlight a recently described role for bacterial superantigens in promoting acute nasopharyngeal infection, and discuss how these immune system activating toxins could be crucial to initiate the autoimmune process in rheumatic heart disease.

Background: Group A streptococcus (GAS) is the most common bacterial etiology of pharyngitis but is difficult to distinguish clinically from viral pharyngitis. There are benefits to early antibacterial treatment of GAS pharyngitis, but administering antibiotics to children with viral pharyngitis is ineffective and costly.

Fusobacterium necrophorum (Fn), a gram-negative anaerobe, is increasingly implicated as an etiologic agent in older adolescents and young adults with sore throat. Inadequately treated Fn pharyngitis may result in suppurative complications such as peritonsillar abscess and Lemierre's syndrome. Data from the literature suggest that the incidence of life-threating complications in these age groups from Fn pharyngitis (Lemierre's syndrome) in the United States exceeds those associated with group A beta-hemolytic streptococcal (GAS) pharyngitis (acute rheumatic fever).
