چکیده
A newly developed rapid coagglutination test for identifying Haemophilus influenzae type b organisms isolated from clinical specimens correlated 100% with the slide agglutination test but was 100- to 200-fold more sensitive.

Identification of Haemophilus influenzae type b by a monoclonal antibody coagglutination assay.
A coagglutination assay using monoclonal antibody is described for the identification of Haemophilus influenzae type b. An immunoglobulin G2a monoclonal antibody, Hb-2, directed against a serotype-specific outer membrane protein of H. influenzae type b was adsorbed to Staphylococcus aureus Cowan 1 cells. In a dot enzyme immunoassay, Hb-2 reacted with 453 of 455 H. influenzae type b isolates and...
متن کاملDETECTION OF HAEMOPHILUS INFLUENZAE TYPE B IN CEREBROSPINAL FLUID OF SUSPECTED CHILDREN WITH MENINGITIS BYPCR
ABSTRACT Background: A polymerase chain reaction (PCR) assay with primers from "hpd" gene was compared with culture for the detection of Haemophilus influenzae type b (Hib) in CSF samples from children suspected of meningitis. Methods: 300 cerebrospinal fluid (CSF) samples from suspected meningitis cases were studied by culture (Leventhal & Chocolate Agar) and PCR. Results: The latter...
متن کاملImmunogenicity and Efficacy of Different Haemophilus influenzae type b Vaccines
Haemophilus influenzae, a major cause of meningitis in young children leading to death and other neurological sequelae. The disease leaves 15 to 35% of the survivors with permanent disabilities, such as, mental retardation or deafness. Despite the availability of new and more powerful antibiotics children with Hib meningitis still suffer from high mortality or morbidity. The emergence of multir...
متن کاملComparison of staphylococcal coagglutination, latex agglutination, and counterimmunoelectrophoresis for bacterial antigen detection.
Soluble antigens of Haemophilus influenzae type b, Streptococcus pneumoniae, Neisseria meningitidis, and group B streptococcus were looked for in cerebrospinal fluid, serum, and urine by using the staphylococcal coagglutination test, latex agglutination test, and counterimmunoelectrophoresis. The staphylococcal coaggultination and latex agglutination tests were more sensitive than counterimmuno...
متن کاملA preliminary study on the use of counterimmunoelectrophoresis and coagglutination methods in the diagnosis of bacterial meningitis.
The usefulness of counterimmunoelectrophoresis (CIEP) and coagglutination (COAG) methods in the diagnosis of bacterial meningitis was evaluated. Out of the 31 cerebrospinal fluid (CSF) specimens which had a cell count of>5 x106wbc/l and were negative on gram stain and culture, pneumococcal antigens were detected in four specimens and Haemophilus influenzae type b antigen was detected in one spe...
