ABSTRACT
Numerous field isolates of Moraxella bovis have previously been classified by serological techniques into seven serogroups, each defined by homologous cross-reaction with antisera prepared against purified pili of a single prototype strain. The gene encoding pilin from each of the prototype strains has been characterized by nucleotide sequence determination. The coding sequences show extensive homology (70 to 80%) while the proximal downstream sequences show a dichotomy into nonhomologous sets. The pilin genes of three more strains were also characterized. The presence of an additional, partial pilin gene in each prototype strain was confirmed by Southern blot analysis, and the partial pilin genes from two strains of one serogroup were characterized by sequence determination. Features of the pilin gene sequences are considered in relation to pilin gene inversion and the serological variants of strains which may arise from gene inversion events.
