The importance of non-group A streptococci as etiologic agents of acute pharyngitis in endemic circumstances is unclear. The authors attempted to clarify this issue in patients undergoing throat culture for acute pharyngitis in a suburban pediatric practice. Of 6,694 throat cultures, 2,243 (34%)

Beta-hemolytic group A streptococcus (Streptococcus pyogenes) is the most common bacterial agent associated with the upper respiratory tract infections in humans. The most frequently group A streptococcus-associated disease is pharyngitis. Males and females are equally affected by group A

Role of beta-hemolytic group C streptococci in pharyngitis: incidence and biochemical characteristics of Streptococcus equisimilis and Streptococcus anginosus in patients and healthy controls.

The biochemical characteristics and the isolation rates of the two Lancefield group C streptococcal species (S. equisimilis and S. anginosus) from patients with pharyngitis and asymptomatic controls were compared. Some 239 strains of beta-hemolytic group C streptococci were isolated from 1,480

We used an ELISA to determine the levels of specific anti-GAS carbohydrate IgG, IgM and IgA in 34 patients with acute rheumatic fever (ARF) with or without carditis, in 15 patients with acute glomerulonephritis (AGN) and in 18 control patients with noncomplicated GAS pharyngitis. Patients with ARF

The antibody response to the group A carbohydrate moiety of the streptococcal cell wall is of special interest because of its postulated role in the pathogenesis of rheumatic valvulitis. The immune response to this somatic antigen was measured in 159 children with culture-proved group A

Rapid antigen detection testing in diagnosing group A beta-hemolytic streptococcal pharyngitis.

Group A beta-hemolytic streptococcus (GABHS) is the most common bacterial cause of acute pharyngitis. Clinical criteria alone are not reliable enough to diagnose GABHS pharyngitis. Microbiological-testing is required for correct diagnosis. Although a throat swab culture remains the gold standard for

Diagnosis of streptococcal pharyngitis by detection of Streptococcus pyogenes in posterior pharyngeal versus oral cavity specimens.

Carbohydrate antigen detection, nucleic acid probe detection, and bacterial culture are commonly used to confirm group A streptococcus (GAS) pharyngitis. Compared to standard throat swab specimens, the sensitivities of these tests with mouth specimens are poor. When testing for GAS pharyngitis, the

BACKGROUND Trehala manna (Shekar tighal) is a cocoon-shaped manna produced by larval activity of Curculionidae family on some Echinops species. In Persian traditional medicine, it is used not only for the treatment of fever and constipation but also for sore throat, influenza and some other viral

Group A streptococci (GAS) cause 20-30% of pediatric pharyngitis episodes, which are a major cause of ambulatory care visits. Therefore, a strategy to prevent GAS dissemination in children could significantly benefit public healthcare. Contextually, we assessed the possibility of employing

Central role of a bacterial two-component gene regulatory system of previously unknown function in pathogen persistence in human saliva.

The molecular genetic mechanisms used by bacteria to persist in humans are poorly understood. Group A Streptococcus (GAS) causes the majority of bacterial pharyngitis cases in humans and is prone to persistently inhabit the upper respiratory tract. To gain information about how GAS survives in and

One hundred consecutive cases of 'first attack' of acute rheumatic fever were studied. There were 52 males and 48 females, constituting 1.12% of total hospital admissions. Nearly 10% of children were below the age of 5 years, stressing the early onset of rheumatic fever in tropics. Only 47% gave a

Rapid antigen detection tests (ADTs) are promoted for identification of group A streptococci (GAS) in the upper respiratory tract. Although debate persists about their sensitivity, most investigators consider ADTs to be highly specific. Nevertheless, reports continue to describe false-positive ADT

Streptococcus pyogenes (group A streptococcus [GAS]) causes 600 million cases of pharyngitis each year. Despite this considerable disease burden, the molecular mechanisms used by GAS to infect, cause clinical pharyngitis, and persist in the human oropharynx are poorly understood. Saliva is
