Diabetic ketoacidosis is a feared complication in patients with diabetes mellitus and poses high risk of mortality and morbidity unless treated in timely manner. Infection is one of the most common precipitating factors for the development of diabetic ketoacidosis. Bacteremia with Group A and Group B beta hemolytic streptococcal strains are well known, however nonenterococcal Group D strains su...

The methods of Lancefield and of Griffith for grouping and typing hemolytic streptococci have greatly facilitated studies on the relationship of the hemolytic streptococcus to human disease. Strains from human disease fall into Lancefield's Group A by the precipitin test.5 Exceptions occur, but they are rare.' Group A consists of about 30 types which can be identified by another precipitin test...

There appears to be a resurgence of puerperal sepsis due to a historically important pathogen, group A beta-hemolytic streptococcus.

Streptococcus agalactiae, also known as group B Streptococcus, is an aetiological agent of urinary tract infection (UTI) in adults, including cystitis, pyelonephritis and asymptomatic bacteriuria (ABU). Whereas ABU-causing S. agalactiae (ABSA) have been shown to grow achieve higher culture denstity human urine compared uropathogenic (UPSA) other phenotypic distinctions between isolated from dif...

Introduction The acronym PANDAS reveals a pediatric autoimmune neuropsychiatric disorder associated with Streptococcus pyogenes infection. This disorder is defined by: (a) the presence of obsessive-compulsive disorder (OCD) or tics; (b) abrupt onset and remitting/relapsing course; (c) prepuberal onset of all symptoms; (d) temporal association with a group A b-hemolytic S. pyogenes infection; (e...

Since the division of the Streptococcus genus into enterococci, lactococci, and streptococci in 1984, many changes in the nomenclature and taxonomy of the Streptococcus genus have taken place. The application of genetic comparisons has improved the proper classification of the different species. The Lancefield system of serogrouping the streptococci by the expression of beta-hemolysis on blood ...

The Phoenix system (Becton Dickinson Diagnostic Systems, Sparks, MD) was evaluated for identification (ID) to the species level of streptococci and enterococci. Two hundred clinical isolates were investigated: beta-hemolytic streptococci (n = 50), Streptococcus pneumoniae organisms (n = 46), viridans group streptococci (n = 31), Enterococcus faecium (n = 36), Enterococcus faecalis (n = 25), and...

BACKGROUND For proper treatment of bacterial infections in mink, knowledge of the causative agents and their antimicrobial susceptibility patterns is crucial. The used antimicrobials are in general not registered for mink, i.e. most usage is "off-label". In this study, we report the patterns of antimicrobial resistance among pathogenic bacteria isolated from Danish mink during the period 2014-2...
