The host immunologic response to group A streptococcal infections gives rise to numerous
antibodies directed against cellular and extracellular bacterial antigens. For determining …

We report here on the development of enzyme-linked immunosorbent assays (ELISAs) for
antibodies to types II and III group B streptococci. Streptococcal antigens were prepared by …

Laboratory aids for the diagnosis of acute rheumatic fever include the determination of
antibodies to streptococcal extracellular products, the elevation of which is a confirmatory …

Streptococcal serology is a cornerstone in the diagnosis of acute rheumatic fever (ARF), a
postinfectious sequela associated with group A Streptococcus infection. Current tests that …

The levels of streptococcal antibody titers in populations with or without rheumatic fever from
an area with a relatively high incidence of rheumatic fever and an area with a low incidence …

Group B streptococcal antigens stimulated tumor necrosis factor alpha (TNF-alpha),
interleukin-1 (IL-1), and IL-6 production in human blood cultures in a concentration-and time …

The group A streptococcal sequela acute rheumatic fever (ARF) has been associated with
immunological cross-reactivity between streptococcal and heart proteins. To identify …

A highly sensitive hybrid assay, based on immuno polymerase chain reaction (immuno-
PCR) and enzyme-linked immunosorbent assay (ELISA) techniques, was developed for the …

Heart-reactive antibody is known to be produced in animals immunized with group A
streptococci. However, the detection and quantitation of these antibodies and their …

This paper deals with the fluorescent antibody (FA) method for identifying six commonly
occuring and two rare groups of streptococci by using commercially prepared (Difco) …
