  • Title: Ultrastructural study on the adherence of Branhamella catarrhalis to oropharyngeal epithelial cell.
    Author: Ahmed K, Rikitomi N, Nagatake T, Matsumoto K.
    Journal: Microbiol Immunol; 1992; 36(6):563-73. PubMed ID: 1381805.
    Abstract:
    In the present study, it was observed that Branhamella catarrhalis adhere to the microplicae of the oropharyngeal epithelial cells. Both long and short microplicae patterns are present on the surface of oropharyngeal epithelial cells and the adherence ability of fimbriated Branhamella catarrhalis also varies according to the microplicae pattern. It was found that Branhamella catarrhalis attached more to one surface of the epithelial cell than to the other, suggesting that the presence of receptors are more on one surface than on the other. Branhamella catarrhalis did not attach to the mucus layer but directly to the epithelial cell surface. Ruthenium red staining specimen showed that Branhamella catarrhalis attached to a granular ruthenium red positive layer on the microplicae and also to a ruthenium red positive component, external to the unit membrane of the epithelial cell membrane.
