objective(s) rapid tests for detection of streptococcus agalactiae or group b streptococci (gbs) at the onset of labor are needed to permit early intrapartum antibiotic prophylaxis. this study aimed to evaluate the pcr assays targeting the 16s ribosomal rna gene (16s rdna) for detection of the gbs in comparison with a specific culture method. materials and methods two swabs were used to obtain ...

Streptococcal bacteria are among dangerous human pathogens with major prevalence worldwide. A good vaccine against streptococcal bacteria should have epitopes that confer protection from infection by different streptococcal bacteria types. we aimed was to recognize the most immunogenic and conserved epitopes of streptococcal bacteria, which could be a potential candidate for vaccine development...

sydenham’s chorea is a delayed complication of group aßhaemolytic streptococcal infections and forms one of the majorcriteria of acute rheumatic fever.it is characterised bychorea, muscular weakness, and a number of neuropsychiatricsymptoms. it is considered to be an autoantibody mediated disorderwith the evidence suggesting that patients with sydenham’schorea produce antibodies that cross reac...

Invasive group A streptococcal infection is a severe disease with high mortality. Invasive group A streptococcal infection may arise after pelvic inflammatory disease. Pelvic inflammatory disease in postmenopausal women is rare. Here, we report a unique case of a postmenopausal woman with fatal invasive group A streptococcal infection due to pelvic inflammatory disease and an extraordinary cour...

BACKGROUND The classical neurological disorder after group A beta haemolytic streptococcal infection is Sydenham's chorea. Recently a tic disorder occurring after group A streptococcal infection has been described and termed PANDAS (paediatric autoimmune neuropsychiatric disorders associated with streptococcal infection). It is proposed that antibodies induced after group A streptococcal infect...

Erythema nodosum (EN) has been associated with various infectious and noninfectious diseases. A total of 39 EN patients seen between May 2005 and February 2012 were evaluated retrospectively in this study. The etiology of EN was established in 22 of the 39 children (56.4%). Streptococcal infection was the most common cause (23%), followed by tularemia (10.2%) and tuberculosis (latent tuberculos...

Streptococcus spp. are gram-positive bacteria and common human pathogens commensals, causing diseases of various organs in children adults. They etiological factors scarlet fever, pharyngitis, tonsillitis, pneumonia, endocarditis, erysipelas, impetigo, meningitis, necrotising fasciitis, sepsis, among others. The post-streptococcal syndrome is a presumed autoimmune condition that has been associ...

Streptococcus spp are opportunistic pathogens that normally reside in the upper respiratory, intestinal, lower urinary, and genital tracts but can cause localized infection or septicemia in dogs of all ages. A retrospective study of streptococcal infection in 393 dogs was conducted to identify the species of Streptococcus isolated, determine demographics of affected dogs, and characterize the d...
