Morphological variations of Haemophilus parasuis strains.
Haemophilus parasuis strains isolated from the noses of apparently healthy animals and from animals with pathological conditions were examined for the presence of a capsule, for their ability to agglutinate in acriflavine or after boiling, and for their peptide profile after polyacrylamide gel electrophoresis (PAGE). The capsule was identified by precipitation against hexadecyl trimethylammoniu...
متن کاملDifferences in phagocytosis susceptibility in Haemophilus parasuis strains
Haemophilus parasuis is a colonizer of the upper respiratory tract of healthy pigs, but virulent strains can cause a systemic infection characterized by fibrinous polyserositis, commonly known as Glässer's disease. The variability in virulence that is observed among H. parasuis strains is not completely understood, since the virulence mechanisms of H. parasuis are largely unknown. In the course...
متن کاملHaemophilus parasuis diagnostics
In the past few years, our understanding of the dynamics of Haemophilus parasuis infection has greatly improved. Techniques such as polymerase chain reaction (PCR) for detection of this microorganism in clinical samples and genotyping of field isolates have certainly enhanced our knowledge on prevalence and epidemiology of infection. Although we still have a long way to go regarding the develop...
متن کاملComplete genome sequence of Haemophilus parasuis SH0165.
Haemophilus parasuis is the causative agent of Glässer's disease, which produces big losses in swine populations worldwide. H. parasuis SH0165, belonging to the dominant serovar 5 in China, is a clinically isolated strain with high-level virulence. Here, we report the first completed genome sequence of this species.
متن کاملGenome sequence of Haemophilus parasuis strain 29755
Haemophilus parasuis is a member of the family Pasteurellaceae and is the etiologic agent of Glässer's disease in pigs, a systemic syndrome associated with only a subset of isolates. The genetic basis for virulence and systemic spread of particular H. parasuis isolates is currently unknown. Strain 29755 is an invasive isolate that has long been used in the study of Glässer's disease. Accordingl...
