streptococcus dysgalactiae subspecies equisimilis is one of the pyogenic group c and g streptococcus, which may be found in the normal gastrointestinal and genitourinary flora of a healthy human. many cases have been reported in literature; however, reports of septic arthritis due to this agent without predisposing factors are extremely rare. diagnosis of this agent is possible in advanced labo...

background and aim . gingivitis is a reversible inflammatory reaction seen with various degrees in most individuals aged 17 to 22 years. the aim of this study was to compare the effects of two herbal extracts on streptococcus salivarius and streptococcus sanguis. materials and methods . aqueous alcoholic root extracts of malva sylvestris and salvadora persica were prepared and tested on pseudom...

The bacteriophages of ~-hemolytic streptococci studied by Evans (1-4) were classified into several races or types. I t is clear from this early work that the phages demonstrated some degree of specificity for streptococcal groups. For instance, a bacteriophage which lysed almost all group C streptococci did not lyse group A streptococci. However, much of this work was done prior to the serologi...

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...

Sheep blood agar containing 23.75 microgram of sulfamethoxazole and 1.25 microgram of trimethoprim (SXT-BA) per ml was compared with conventional sheep blood agar (SBA) for isolating group A and B streptococci from throat cultures. This selective medium allowed much better recovery of group A and B streptococci and suppressed the growth of the normal flora, including "viridans" streptococci. In...

they used standardized regression coefficients, but this was not clarified.) Also, there are a number of minor typographic errors. The most significant findings were that . .. program impact was primarily on savings and socialization of the aged rather than health and nutrition." Moreover, in 1976, less than 3 percent of the Boston area aged (65 or more) residents participated in the program, a...

The minute streptococci comprise a unique group with respect to their physiological and serological characteristics, as well as their nutritional requirements. Serologically they constitute Lancefield's serological group F and type 1, group G. The type specific antigen that defines type 1 in both serological groups appears to be identical, thus resulting in cross reactions among these streptoco...

Skin and Soft Tissue Infections (SSTI) resulting from cat bites most commonly occur due to Pasteurella infection. However, other pathogens such as Β-Hemolytic Streptococci

BACKGROUND Acute rheumatic fever is a major cause of heart disease in Aboriginal Australians. The epidemiology differs from that observed in regions with temperate climates; streptococcal pharyngitis is reportedly rare, and pyoderma is highly prevalent. A link between pyoderma and acute rheumatic fever has been proposed but is yet to be proven. Group C beta-hemolytic streptococci and group G be...
