Distribution of different species of the Bacteroides fragilis group in individuals with Japanese cedar pollinosis.

چکیده
We investigated associations of species of the Bacteroides fragilis group with Japanese cedar pollinosis (JCPsis). Cell numbers of Bacteroides fragilis and Bacteroides intestinalis were significantly higher in JCPsis subjects than in non-JCPsis subjects before the pollen season. They correlated positively with both symptom scores and JCPsis-specific immunoglobulin E levels.

متن کاملEnhanced production of IgE anti-Japanese cedar pollen specific antibodies by peripheral blood B cells from patients with Japanese cedar pollinosis.
BACKGROUND IgE antibodies against Japanese cedar pollen (JCP) play an important role for the pathogenesis of the cedar pollinosis, but the mechanism of their production has been unclear. We explored the capacity of peripheral blood B cells from pollinosis patients to produce anti-JCP specific IgE. METHODS Peripheral blood B cells from 16 pollinosis patients and 9 normal subjects were cultured...
