An application of outer membrane protein p6-specific enzyme-linked immunosorbent assay for detection of haemophilus influenzae in middle ear fluids and nasopharyngeal secretions.

An enzyme-linked immunosorbent assay specific to outer membrane protein P6 (P6-ELISA) was applied for detecting Haemophilus influenzae in middle ear fluids (MEFs) from acute otitis media (AOM) patients and in nasopharyngeal secretions (NPSs) from acute rhinosinusitis patients. P6-ELISA had a sensitivity of 83.3% for MEFs and 71.

Evaluation of a rapid immunochromatographic ODK-0901 test for detection of pneumococcal antigen in middle ear fluids and nasopharyngeal secretions.

Since the incidence of penicillin-resistant Streptococcus pneumoniae has been increasing at an astonishing rate throughout the world, the need for accurate and rapid identification of pneumococci has become increasingly important to determine the appropriate antimicrobial treatment. We have evaluated an immunochromatographic test (ODK-0901) that detects pneumococcal antigens using 264 middle ear fluids (MEFs) and 268 nasopharyngeal secretions (NPSs). A sample was defined to contain S.

Factors associated with the presence of drug-resistant bacteria and recurrent acute otitis media in children--a study in a private clinic.

Conclusions: The proportion of drug-resistant bacteria was lower than previous reports. In children with acute otitis media (AOM), lower age, presence of multiple bacteria, and otitis media with effusion (OME) represented significant factors for recurrent AOM and the presence of drug-resistant bacteria.

Objective: Recently, the proportion of drug-resistant bacteria has been increasing in children with AOM.

[Epidemiological survey of pneumococcus serotypes in pediatric patients with acute suppurative otitis media].

To determine the distribution of Streptococcus pneumoniae serotypes isolated from patients under 6 years of age with acute suppurative otitis media, to calculate the serotype coverage of 7-valent pneumococcal conjugate vaccine, and to clarify trends in PCG-resistant Streptococcus pneumoniae, we conducted a one-year prospective study from April 2005 to March 2006 at 10 medical institutions in Hokkaido, Miyagi, Chiba, Tokyo, Kanagawa, and Mie, Japan. Specimens collected by tympanotomy or myringotomy numbered 856, and 691 strains were isolated from 599 specimens. Of these, 219 isolates (31.
