Clinical application of immunofluorescence. 3. Identification of Lancefield group B streptococci.
The identification of Lancefield group B streptococci with immunofluorescence was studied after significant differences between the precipitin and immunofluorescent results were noted. It was found that strains of group B streptococci, unlike groups A, C, and G streptococci, do not reliably react with a fluorescein isothiocyanate-labeled conjugate that contains antibodies mainly against C polys...
متن کاملIdentification of group B streptococci by immunofluorescence staining.
Gamma globulin fractions of rabbit antisera prepared with whole cell vaccines of group B types Ia, Ib, II, and III and labeled with fluorescein isothiocyanate stained group B streptococci type specifically. Type Ic cells, which contain the Ia polysaccharide antigen of type Ia and the Ic protein antigen of type Ib, were specifically stained by both Ia and Ib conjugates. A group B conjugate pool ...
متن کاملGrouping and detection of group B streptococci by immunofluorescence.
Forty-nine clinical isolates of group B streptococci (GBS) were correctly grouped from broth culture by the Fluoro-Kit immunofluorescence test. A further 82 beta-haemolytic streptococci of groups A, C, D, F, and G were tested and gave no cross-reactions. The test was simple to perform and gave clear results. The Fluoro-Kit reagents, however, failed to detect GBS in 21 (51%) of 41 smears of rect...
متن کاملIdentification of a highly encapsulated, genetically related group of invasive type III group B streptococci.
Type III group B streptococci (GBS) isolated from Tokyo and Salt Lake City were classified according to the similarity of HindIII and Sse83871 restriction digest patterns (RDPs) of bacterial DNA. The bacteria were clustered into three RDP types, with excellent correlation between subtyping based on the two enzymes. The majority (91%) of invasive isolates obtained from neonates were RDP type III...
