The proposed project aims to continue research for development of a vaccine protective against the pathogenic equine parasite Strongylus vulgaris. The ongoing work to establish appropriate in vitro models to screen the effect of candidate vaccine antigens/adjuvants will be continued. Cytokine screenings in cultures of equine PBMC and intestinal organoids will enable studies of both the systemic (PBMC) and local (organoids) response to parasite antigens. Our main antigen candidate, the recombinant protein SvSXP, will be evaluated together with a novel adjuvant, G3, first in our in vitro systems and thereafter in an immunisation trial in collaboration with experts on parasite immunology at the University of Kentucky. In search of additional vaccine antigens a bacteriophage cDNA library constructed from migrating S. vulgaris larvae will be utilized. Bacteriophage clones expressing promising larval antigens will be further propagated and tested for inclusion in the vaccine formula.
Projektet syftar till att fortsätta utvecklingen av ett vaccin som skyddar mot hästens farligaste inälvsparasiter, Strongylus vulgaris. Det redan påbörjade projektet med att etablera in vitro modeller för att screena immunreaktioner mot olika kandidatantigen/adjuvans planeras fortsätta. Genom att mäta cytokinsvaret i cellkulturer bestående av mononukleära blodceller och tarmorganoider kan både de systemiska (blodceller) och lokala (organoider) immunreaktionerna mot olika parasitantigen utvärderas. Kandidatantigenet SvSXP kommer tillsammans med ett nytt adjuvans, G3, att utvärderas först in vitro och sedan i ett vaccinationsförsök i samarbete med erfarna parasitimmunologer vid University of Kentucky. För att finna ytterligare vaccinantigen kommer ett redan existerande S.vulgaris cDNA bibliotek att användas. Kloner som visar potential att inkluderas i vaccinformuleringen kommer att testas och utvärderas med den etablerade metodologin.

Young horses can develop cervical vertebral stenotic myelopathy and ataxia, known as "wobbler syndrome" and associated with loss of breeding value, reduced athletic potential and euthanasia. Some wobblers have osteochondrosis of their vertebral facet joints, but it is now known how this relates to …

The alarming development of triple resistant Parascaris spp. is an increasing threat to foal health and the equine industry, due to the risk of increasing veterinary costs and loss of foals. A continued development of triple resistant roundworms in Sweden would be devastating for foals and …

Harness racing is hazardous as horses are running in close proximity at high speeds. Thus, an effective communication between driver and jockey-horse via rein signals to the bit is essential for safety reasons and horse welfare. However, scientific studies on rein tension in Standardbred trotters …

Just going to the bathroom is contributing to algae blooms and climate change. Sweden alone releases roughly 15400 tonnes of N and 240 tonnes of P into lakes, rivers and seas, through municipal wastewater (including after treatment). Urine contains 80% of the plant nutrients found in wastewater and …

Heat stress is expected to be of major concern in Swedish animal production systems in the future. The air temperatures in parts of Sweden are expected to correspond to today's temperatures in southern Europe, where livestock experience heat stress today. Excessive thermal load affects the welfare …

Poultry have a strong motivation for foraging and spend most of the day pecking and searching for food. In commercial conditions, the birds are fed a pellet diet, which is consumed very quickly. Consequently, hens spend a large part of the day engaging in abnormal non-food related pecking …
