WebSalmonella enterica serovar Typhimurium variant Copenhagen was isolated from 5 of 152 (3.3%) feral pigeons from the city of Ghent (Belgium) and from 26 pooled fecal samples from 114 pigeon lofts (22.8%). These isolates belonged to phage type (PT) 99. WebResistance plasmids carrying virulence genes of serovar specific plasmids, including the spv region, were also detected. This review will focus on hybrid virulence–resistance plasmids found in Typhimurium and its monophasic 4,5,12:i:- variant, Enteritidis and Choleraesuis, which rank among the most common and/or invasive nontyphoid serovars.
