N2 - The species [Pasteurella] pneumotropica has been reclassified into the new genus Rodentibacter, within the family Pasteurellaceae. Along with the type species (Rodentibacter pneumotropicus) of the new genus, seven new species have been named. These organisms were formerly mainly known as the [P.] pneumotropica complex and [P.] pneumotropica was considered as the most important Pasteurellaceae species colonizing laboratory rodents. The aim of this review is to update the veterinary relevant aspects of clinical manifestations, pathogenesis, virulence and diagnostics of members of Rodentibacter with a focus on the most important species from a veterinary perspective. The organisms are obligate commensals of the mucous membranes and members of Rodentibacter are not able to persist for long in the environment. Members of Rodentibacter spp. are responsible for the most prevalent bacterial infections in laboratory mice and rats, but are also common in rodents outside laboratory settings. Some Rodentibacter spp. produce mainly localised disease in connection with favouring factors and seldomly act as primary pathogens in healthy immunocompetent animals. The subclinical infection with Rodentibacter spp. can affect the results of certain types of research using contaminated animals thus placing them on a list of microbes which are often not tolerated in experimental rodent facilities. The presences of RTX toxins, YadA-like proteins and a capsule with possible role in the pathogenesis have been described. Some species of Rodentibacter are able to form robust biofilms which might be involved in colonisation and persistence within the host. Current possibilities for diagnostics and differentiation among Rodentibacter spp. are outlined and options for treatment and control are provided.
