title: Immunological and biological relationship among flagellin of Pseudomonas aeruginosa, Burkholderia cepacia and Stenotrophomonas maltophilia.
abstract: The flagellar protein (flagellin) was isolated and purified from strains of Pseudomonas aeruginosa, Burkholderia cepacia and Stenotrophomonas maltophilia. A significant difference was observed in the molecular weight of different flagellin preparations obtained from these bacterial isolates. Antiserum prepared against S. maltophilia flagellin did not react with flagellin of P. aeruginosa or/and B. cepacia on Immunoblot or in indirect ELISA. In addition the anti-flagellin did not agglutinate P. aeruginosa and B. cepacia. No inhibition of motility of P. aeruginosa and B. cepacia was observed in presence of antiserum; though the latter inhibited the motility of S. maltophilia. The results of the present study prove that no specific relationship existed among all the studied flagellar proteins obtained from closely related bacteria.
