				 Background: Swine atrophic rhinitis (AR) is a multiple chronic respiratory diseasemainly caused by porcine Bordetella bronchiseptica (Bb) and Toxigenic Pasteurella multocida (T+Pm). There are two challenge models using Bordetella bronchiseptica and Pasteurella multocida. The first model is to treat pigs with Bordetella bronchiseptica followed by Toxigenic Pasteurella multocida infection. Another model is to inoculate pigs with Bordetella bronchiseptica and Pasteurella multocida simultaneously. So far, there is no report about comparison of these two challenge models as for their effectiveness to establish infection.
Methods: Thirteen 42 day-old piglets were divided into three groups. Pigs in the first group were challenged with Bordetella bronchiseptica followed.. View More»
