Fluorescein isothiocyanate-labelled goat antihuman immunoglobulin (anti-IgG, anti-IgA, anti-IgM) and anticomplement conjugates were used to detect antibody or complement-coated bacteria from the oropharynx of patients with pharyngitis. Throat smears prepared from patients with a positive culture for group A beta-hemolytic streptococci had significantly more bacteria that stained with labelled a...

These studies indicate that a single strain of hemolytic streptococci almost exclusively predominates the bacterial flora in patients with streptococcal infections and in the carrier state. One can proceed with confidence that, in isolating streptococci from throat swabs cultured on blood-agar plates, only a single hemolytic colony need be picked for serological grouping and typing.

Here we present a rare case of infective endocarditis (IE) with Streptococcus canis and Chiari network in an 85 year old female living multiple dogs open skin lower extremity predisposing her to bacteremia. Underlying abnormalities the cardiac chambers such as predisposes higher incidence bacterial seeding causing IE. A is usually asymptomatic no clinical significance but can worsen prognosis I...

Streptococcal disease and columnaris are common in tilapia aquaculture across the globe. Coinfections also but often overlooked or not reported. In present study, we describe clinical presentation of streptococcosis coinfection diseased Nile ( Oreochromis niloticus ), phenotypic (Lancefield grouping, hemolytic pattern, biochemical characteristics, antibiotic susceptibility) genotypic (multilocu...

I t has often been noted that on a blood agar plate seeded with influenzal sputum the colonies of Bacillus influenz6e are most numerous and grow to larger size in the neighborhood of colonies of certain other organisms, notably the staphylococcus. This phenomenon led the authors to conduct various experiments which may be summarized as follows: Blood agar plates were seeded uniformly with a pur...

Wide-zone, alpha-hemolytic streptococci are potential sources of false-positive throat cultures since they can be misinterpreted as beta-hemolytic streptococci. However, quantitative information regarding their occurrence in sick children was not available. Throat swabs from 312 children with pharyngitis were processed conventionally and also with pour-plate methods and examination of the posit...
