Fimbriae and Membranes on Haemophilus parasuis

Journal of Veterinary Medicine, Series B, 1992
SummaryIn the electron microscope an additional layer (glycocalix) of the cell wall and fimbriae on Haemophilus parasuis were shown in thin sections of the infected CAM which have their origin on the CM of the Haemophilus parasuis‐cells. No fimbriation was seen after conventional cultivation.

Serological characterization of Danish Haemophilus parasuis isolates

Veterinary Microbiology, 2004
A total of 103 Danish Haemophilus parasuis field isolates was collected from diseased pigs in connection with routine diagnostics. The isolates were serotyped using indirect haemagglutination (IHA) and for 57 of the isolates the serotyping was also performed by immunodiffusion.

Advances in the quest for virulence factors of Haemophilus parasuis

The Veterinary Journal, 2013
Haemophilus parasuis colonises healthy pigs and is the aetiological agent of Glässer's disease. The pathogenicity of H. parasuis is poorly characterised, while prevention and control of Glässer's disease continues to be challenging. Understanding the pathogenicity of H.

Analysis of Haemophilus parasuis by multilocus enzyme electrophoresis

Veterinary Microbiology, 1997
The diversity among 40 Australian isolates and eight reference strains of Haemophilus parasuis was examined using multilocus enzyme electrophoresis. Thirty-four electrophoretic types (ETs) were recognized with a mean diversity per locus of 0.405. One Australian isolate was located in an ET separated by a considerable distance (> 0.8) from the rest of ...

The cytochrome complement of Haemophilus parasuis

Canadian Journal of Microbiology, 1984
Spectral analyses with subcellular fractions derived from Haemophilus parasuis demonstrated that this organism could synthesize membrane-bound and soluble CO- and NO-binding c-type cytochromes in addition to the membrane-bound cytochromes d, a1, b, and c; cytochromes d, a1, and o were identified as potential oxidases. The membrane-bound and soluble CO-

Development of a genetic manipulation system for Haemophilus parasuis

Veterinary Microbiology, 2005
Haemophilus parasuis is a member of the family Pasteurellaceae and an important respiratory-tract pathogen of swine, which is the etiological agent of Glasser's disease. Because no genetic manipulation system is available for H. parasuis so far, in vivo studies about the role of its genes involved in virulence are unfeasible. Here we demonstrate that H.

Effect of marbofloxacin on Haemophilus parasuis nasal carriage

Veterinary Microbiology, 2012
Haemophilus parasuis is a colonizer of the upper respiratory tract and the causative agent of Glässer's disease in swine. This study focused on the nasal carriage of H. parasuis after treatment with marbofloxacin. Three marbofloxacin treatments (three doses of 2mg/kg body weight [bw] every 24h, two doses of 4 mg/kg bw every 48 h and 8 mg/kg bw in one ...

Sow vaccination modulates the colonization of piglets by Haemophilus parasuis

Veterinary Microbiology, 2010
Haemophilus parasuis is the etiologic agent of Glässer's disease in pigs and a colonizer of the upper respiratory tract of healthy pigs. A good balance between colonization and immunity is important to avoid a disease outbreak. This work studied the colonization of H. parasuis in healthy piglets coming from vaccinated and non-vaccinated sows.

Purification and renaturation of membrane neuraminidase from Haemophilus parasuis

Veterinary Microbiology, 2003
Haemophilus parasuis, which causes polyserositis, polysynovitis, meningitis, septicemia, and pneumonia in pigs, has emerged as an increasing problem in modern swine production systems. Co-factors for and the pathogenesis of H. parasuis disease are not defined. One of the potential virulence factors of H. parasuis is its neuraminidase (sialidase). While

Differences in susceptibility to Haemophilus parasuis infection in pigs.

Canadian journal of veterinary research = Revue canadienne de recherche veterinaire, 2008
In animal breeding programs, deoxyribonucleic acid (DNA) markers can be used to identify sires that are less susceptible to disease. These DNA markers are typically discovered in populations that display differences in susceptibility. To find those differences, it was hypothesized that sires influence their offspring responses to infection with H ...
