| prevalence of o1/k1- and o2/k3-reactive actinobacillus suis in healthy and diseased swine. | a cell surface antigen-typing system was devised for the swine pathogen actinobacillus suis and used to examine the prevalence of different lipopolysaccharide (o) types in healthy and diseased pigs. the strains examined in this study were isolated from a variety of locations in canada and from kansas. lipopolysaccharide preparations of 151 isolates of a. suis were characterized by immunoblotting using polyclonal antisera generated to strains so4 (o1/k1), h89-1173 (o2/k3), and vsb 3714, a rough s ... | 2000 | 11015398 |
| prevalence of actinobacillus pleuropneumoniae, actinobacillus suis, haemophilus parasuis, pasteurella multocida, and streptococcus suis in representative ontario swine herds. | tonsillar and nasal swabs were collected from weanling pigs in 50 representative ontario swine herds and tested for the presence of 5 important bacterial upper respiratory tract pathogens. all but 1 herd (2%) tested positive for streptococcus suis by polymerase chain reaction (pcr); 48% of herds were s. suis serovar 2, 1/2 positive. in all but 2 herds there was evidence of haemophilus parasuis infection. in contrast, toxigenic strains of pasteurella multocida were detected by a p. multocida--enz ... | 2008 | 18505187 |
