BACKGROUND There are three turkey β-adrenoceptors: the original turkey β-adrenoceptor from erythrocytes (tβtrunc, for which the X-ray crystal structure has recently been determined), tβ3C and tβ4C-receptors. This study examined the similarities and differences between these avian receptors and mammalian receptors with regards to binding characteristics and functional high and low affinity agoni...

We examined Bordetella avium for virulence factors common to Bordetella pertussis, including pertussis toxin, filamentous hemagglutinin, adenylate cyclase, dermonecrotic toxin, and tracheal cytotoxin. B. avium produced a dermonecrotic toxin and a tracheal cytotoxin. The dermonecrotic toxin of B. avium is a 155,000-molecular-weight, heat-labile protein which was lethal for mice, guinea pigs, you...

To the editor: In a recent Eurosurveillance issue, Kinross et al. [1] describe a cross-border outbreak of Salmonella Stanley in the European Union, which could be traced back to a contamination in the turkey production chain. The aetiological clone is mono-resistant to nalidixic acid and characterised by a novel pulsed-field gel electrophoresis (PFGE) type. We agree with Kinross et al. that the...
