Characterization of the proteins ofBordetellaisolates from turkeys in the UK by polyacrylamide gel electrophoresis

Abstract

The proteins of seven Bordetella bronchiseptica-like isolates were examined by polyacrylamide gel electrophoresis (PAGE). They were compared with three similar isolates from overseas, one of which is the type strain of Bordetella avium, and with Bordetella bronchiseptica NCTC 452T and Alcaligenes faecalis NCTC 415. Apart from Alcaligenes faecalis, there was strong homology between the isolates suggesting their close relationship, but minor differences were apparent, too. The significance of these is uncertain.
