Detection of Haemophilus influenzae type b antigenuria by Bactigen and Phadebact kits.
نویسنده
چکیده
Two commercially available reagents, latex particles (Bactigen) and Staphylococcus aureus suspensions (Phadebact), were compared for the detection of the capsular polyribitol phosphate antigen of Haemophilus influenzae type b in 18 pediatric patients with proven infections due to H. influenzae type b. Whereas both tests nearly equally detected the antigen in the first urine specimens from the patients, the latex test remained positive significantly longer than did the Phadebact test for serial urine specimens. We conclude that the Bactigen test is slightly more sensitive than the Phadebact test for detecting urinary H. influenzae type b antigen.

The Bactigen latex agglutination and Phadebact coagglutination tests were evaluated for their ability to detect bacterial antigens of Haemophilus influenzae type b, Streptococcus pneumoniae (83 serotypes) and Neisseria meningitidis groups A, B, C, and Y in 214 samples of cerebrospinal fluid (CSF). Bactigen latex agglutination was more sensitive than Phadebact coagglutination: it detected 87% (5...
متن کاملHaemophilus influenzae type b antigenuria in children.
Detection of Haemophilus influenzae type b (HIb) antigenuria by latex agglutination has been shown to be sensitive, specific, and rapid. In children, antigenuria persisted for a mean duration of 10 days and a maximum of 18 days. Antigenuria was demonstrated in 25 of 30 patients with HIb infection but not in 62 with other types of infection. In five children, antigenuria confirmed the diagnosis ...

Thirty-eight pediatric outpatients with pneumonia were studied by counterimmunoelectrophoresis for the presence of Haemophilus influenzae type b or pneumococcal antigenuria. Of the 38 patients eight (21%) had H influenzae type b antigenuria and two (5%) had pneumococcal antigenuria. H influenzae type b antigenuria was detected more frequently in patients less than 2 years of age than in older c...

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...
