2015-02-08 The haemagglutination and tissue culture adherence properties of 20 isolates of Moraxella catarrhalis obtained from the sputum of elderly patients with lower respiratory tract infections were compared with those of 20 isolates of M. catarrhalis obtained from the nasopharynx of elderly persons colonised by the organism. Eighty percent of isolates from the infected group as opposed to 5% of M. catarrhalis (formally known as Branhamella catarrhalis) has undergone several name changes in the past 100 years [19-20]. It was first described at the end of the nineteenth century when it was named Micrococcus catarrhalis, and it was later changed to Neisseria catarrhalis because of its similarity in phenotype and ecological niche to 2000-04-01 Virulence factor.
