| comparative virulence of some english strains of haemophilus pleuropneumoniae serotypes 2 and 3 in the pig. | between 10(7.5) and 10(8.1) viable organisms of four english and one danish strain of haemophilus pleuropneumoniae serotype 2 and five english strains of serotype 3 were inoculated intranasally into groups of conventional pigs. among the english isolates of both serotypes there were virulent and non-virulent strains. four of the serotype 2 strains, including the danish strain, and two of the serotype 3 strains produced varying degrees of pulmonary consolidation with abscess formation and pleuris ... | 1987 | 3589166 |
| prevalence of pig herds affected by pleuropneumonia associated with haemophilus pleuropneumoniae in eastern england. | a survey for the macroscopic lesions indicative of pneumonic infection in the pig with haemophilus pleuropneumoniae was made in an abattoir in eastern england. a total of 78 herds located in 11 counties of eastern or central england were seen between december 1982 and august 1983. lesions were noted in the batches submitted by 44 (56 per cent) of the 78 herds. a further 16 herds (21 per cent) submitted batches containing pigs affected by pleurisy principally of the caudal lobes but without the p ... | 1985 | 4049707 |
| population-based analysis of actinobacillus pleuropneumoniae apxiva for use as a diva antigen. | apxiva is an rtx toxin of actinobacillus pleuropneumoniae that is a candidate antigen to differentiate infected from vaccinated animals (diva). insertion of isapl1 into the apxiva gene is known to compromise an apxiva-based diva approach, as is potentially a tgg to tga mutation in the apxiva gene. isapl1 was found in 63/349 (18.1%) a. pleuropneumoniae isolates from england and wales including serovars 2, 3, 6-8 and 12. no isapl1 insertions into apxiva were found. only two serovar 3 isolates cont ... | 2010 | 20483193 |

| identification of dfra14 in two distinct plasmids conferring trimethoprim resistance in actinobacillus pleuropneumoniae. | the objective of this study was to determine the distribution and genetic basis of trimethoprim resistance in actinobacillus pleuropneumoniae isolates from pigs in england. | 2015 | 25957382 |
