Expression of Toll-like receptors 2, 4 and 6 in the equine chorioallantois
This study examined the expression of TLR 2, 4 and 6 as transcript and protein in the placenta (chorioallantois) of 14 foals born alive. By PCR, all examined placental samples contained TLR 2, 4 and 6 transcripts. Using immunohistochemistry, trophoblasts and allantoic epithelium were immunopositive for TLR 2, 4 and 6 in all placental samples. The majority of placental samples contained TLR 4 and 6 positive stromal cells and vascular smooth muscle cells. Since these results confirm the expression of TLR 2, 4 and 6 in different cell populations of the equine placenta, they are the basis for studies into the pathogenesis of T...

The porcine tonsils and Peyer’s patches: A stereological morphometric analysis in conventionally and artificially reared piglets
Publication date: Available online 13 November 2018Source: Veterinary Immunology and ImmunopathologyAuthor(s): Sara Prims, Ben Jurgens, Charlotte Vanden Hole, Steven Van Cruchten, Chris Van Ginneken, Christophe CasteleynAbstractSelection for prolificacy in modern pig farming has resulted in increasing litter sizes. Since rearing large litters is challenging, artificial rearing of piglets with a milk replacer is an alternative strategy. It is hypothesized that the development of the piglets’ mucosa-associated lymphoid tissues (MALT) is affected by these artificial conditions. Therefore, the stereologically estimated v...

We also evaluated the effect of a V. anguillarum infection on the transcription of immune-related genes in gnotobiotic European sea bass larvae. Recombinant sea bass ferritin-H was produced, encapsulated in calcium alginate microparticles and orally delivered to sea bass larvae at seven days after hatching. Our results showed V. anguillarum caused an acute infection, resulting in high mortality. The infection significa...

Publication date: Available online 29 July 2018Source: Veterinary Immunology and ImmunopathologyAuthor(s): Milton Levin, Lindsay Jasperse, Erika Gebhard, Estelle Rousselet, Catherine WalshAbstractVeterinary medical examinations, including both physical examination and diagnostic tests, are important to monitor the health of both managed-care and wild marine mammals. However, limited species-specific reagents and assays are available that may contribute to a broader medical examination. This project evaluated if commercially available human and porcine antibodies and reagents would cross-react with manatee (Trichechus manat...

Use of ELISA and Western blot for serological detection of antibodies to E-S antigens of Trichinella spiralis muscle larvae in sera of swine experimentally infected with Trichinella spiralis
Publication date: Available online 29 July 2018Source: Veterinary Immunology and ImmunopathologyAuthor(s): Michał Gondek, Justyna Bień, Zygmunt NowakowskiABSTRACTThe aim of the present study was to evaluate the detection of trichinellosis using ELISA, and to determine the degree of variation of IgG antibodies against excretory-secretory (ES) antigens of T. spiralis muscle larvae. Ten young Polish Large White native breed pigs were experimentally inoculated with a low dose of 300 invasive Trichinella spiralis (T. spiralis) muscle larvae (ML). Pig sera were collected at 7 and 9 days prior to the experimental infection with...

Sheep and cattle exposed to Mycobacterium avium subspecies paratuberculosis exhibit altered total serum cholesterol profiles during the early stages of infection
This study sought to evaluate the levels of total serum cholesterol in the host following exposure to MAP. Blood samples were collected from both sheep and cattle prior to experimental challenge with MAP and at monthly intervals post-challenge. Total serum cholesterol levels in sheep challenged with MAP were significantly elevated at 9 weeks post-inoculation (wpi) in comparison to controls. When stratified based on disease outcome, there was no significant difference in serum cholesterol at the timepoints examined between MAP exposed sheep that were susceptible and those that were resistant to Johne’s disease. There ...

Effect of antigen challenge on dynamics of cd62p and cd41/61 expression on platelets in horses with recurrent airway obstruction (rao)
Publication date: Available online 18 July 2018Source: Veterinary Immunology and ImmunopathologyAuthor(s): Alicja Iwaszko, Hieronim Borowicz, Stanislaw Graczyk, Malwina Slowikowska, Aleksandra Pliszczak-Krol, Artur NiedzwiedzAbstractRecurrent airway obstruction (RAO), also known as heaves, is an allergic respiratory condition that develops in horses following an exposure to aeroallergens in hay and straw. This is manifested by airway hyperreactivity, inflammation, bronchoconstriction, as well as a leukocyte and platelet infiltration into the airways. Platelet activation and an increase in circulating platelet-leukocyte agg...
