This work reveals the results of BAL performed on horses included in a larger study that assessed the relationship of amount and type of inhaled particles in equine stable air on indices of respiratory inflammation in horses and people. During this study an unanticipated and marked elevation in lung eosinophils was detected in a number of the horses. The possible significance and cause of this pulmonary eosinophilia was investigated further, and is the main focus of the work presented.

Abort som orsakas av virus förekommer hos hästar över hela världen, och skapar problem för uppfödare. De främsta bakomliggande virusen är ekvint herpesvirus 1 (EHV-1) och ekvint arterit virus (EAV). Fall inträffar tillföljd av båda virusen varje år i Sverige, och framförallt EHV-1 har varit föremål för mycket forskning för att hitta ett skyddande vaccin. Det finns i Sverige ett avdödat vaccin mot EHV-1 upptaget i FASS. EAV däremot vaccineras det i princip inte mot i landet, men utomlands finns och används i vissa länder både avdödade och attenuerade levande vaccin.

Veterinary hospital care and advanced veterinary services are rapidly growing industries. As of January 1, 2010, veterinary nursing became a licensed vocation, the title of veterinary nurse became protected, and the act regulating competence among the professions of the veterinary field was extended. These changes, along with increased demands and expectations from owners, have given rise to greater demands on the staff's qualifications and have increased the need for well-educated staff with expertise in several different areas. The aim of this study was to find out what the licensed veterinary nurse can do in terms of rehabilitation for the hospitalized equine patient suffering from orthopedic injury. This has been carried out through qualitative interviews with veterinary surgeons experienced in treating such patients, and also by reviewing the relevant literature.

Penicillin G (benzylpenicillin) is the most commonly used antimicrobial substance used in equine medicine today. Two forms of penicillin G are available for equine use; one form is the poorly soluble penicillin G procaine and the other is the very soluble sodium salt. Although penicillin has a wide safety margin and is considered to possess a good tolerance, reactions due to side effects are sometimes encountered, which commonly is named ?penicillin-shock?. The etiology behind penicillin shock in horses is not completely understood, but the most common reason is believed to be procaine toxicity.

EVA, Equine Viral Arteritis, was diagnosed for the first time in 1953 in USA. The disease gained international interest in 1984, when there were several outbreaks of abortion at Thoroughbred studs in USA. EAV, Equine Arteritis Virus, is an RNA virus in the Arteriviridae family. There is only one serotype of EAV but several strains and the strains have different virulence. EAV is transmitted in two different ways: by aerosols, or by venereal transmission.

Elakartad katarralfeber är en dödlig sjukdom hos nötkreatur som orsakas av herpesvirus från får eller gnuer. I områden där båda virusvarianterna finns kan man skilja dem åt genom PCR-metoder. Sjukdomen verkar bero på en virusorsakad obalans i immunförsvaret och karaktäriseras av infiltration och ansamling av CD8+ T-lymfocyter. Infekterade celler kan omvandlas till ?large granular lymphocytes? som orsakar celldöd i flera olika vävnader.

Respiratory disease with airway inflammation as main characteristic is common in the horse. It is a syndrome that is not yet fully understood. The etiology, pathogenesis and classification into different disease states are subjects for discussion and under continuous revision. Despite a number of modern techniques, the diagnostic procedure is challenging. There is no test considered to be gold standard when diagnosing these diseases.

Equine appeasing pheromone (EAP) är ett feromon som avges vid juverområdet på ston under digivningsperioden. Detta feromon har framställts syntetiskt och ingår i produkten ConfidenceEQ som går att köpa receptfritt på apotek och kliniker. Produkten ska göra hästen avspänd och fokuserad och kan användas vid till exempel inlärning och träning samt vid situationer där hästen visar tecken på oro. Situationer där hästägaren själv kan välja att använda EAP är till exempel inför transport, veterinärbesök, hovslagarbesök eller tandundersökningar. Ibland kan detta vara situationer där veterinär sedan behöver sedera hästen för att det ska gå att genomföra vissa undersökningar och behandlingar. Det är därför intressant att undersöka om EAP påverkar sederingsgraden av detomidin, en vanligt förekommande substans för sedering av häst. För att undersöka om EAP påverkar sederingsgraden med detomidin hos häst utfördes en trippelblindad, experimentell, prospektiv, crossover-studie där 8 hästar ingick.

The interest in horses and equestrian sport is constantly increasing, and so is the will in both riders and trainers to learn more about the effect the rider and its equipment have on the horse. The last twenty years, more and more studies have been performed were the horse and its kinematics have been in focus. The access to more advanced technology has made it possible to study areas, which earlier have been hard to reach. The knowledge about kinematics in the horse, and how riders and their equipment interact with the horse?s movement, is also of great interest to veterinarians in equine practice.

Canine herpes virus 1 (CHV-1) är en vitt utbredd smittsam patogen. Viruset tycks verka enzootiskt i hundpopulationer och ger upphov till en livslång latens hos infekterade djur. CHV-1 kan sedan reaktiveras vid exempelvis stress, som vid dräktighet. Hos vuxna hundar får infektionen ofta ett subkliniskt uttryck, men kan också ge upphov till respiratoriska symtom samt genitala blåsor och ögoninfektioner. Dräktiga tikar kan drabbas av fertilitetsproblem, med mumifikation, resorption, dödfödsel samt abort av foster.

Thermography is the assesment of the surface temperature of the horses body and it falls into the categori of physiological imaging. Thermography allows us to portray inflammation and changes in sympathetic tone in a graphical manner. The purpose of this study was to review thermography in equine medicine and to evaluate thermography as an aid in the diagnosis of lamness in horses. Thermography has been helpful to identyfy sprains, stress fractures, shin splints and soft tissue, tendon, ligamentous and nerv injuries and to monitor healing processes during rehabilitation. Routine thermography may reveal inflammatory responses prior to clinical signs. In present study thermograpy gave especially valuabel information in two cases. In one horse reduced blood flow in a. saphena due to a thrombosis were visualised and in the other horse bilateral thoracolumbal radiculopati was diagnosed.

A method for equine intra oral radiology has been tested. In the study, both a digital system with an intraoral sensor connected to a laptop and a system utilizing image plates and digital developing was tested, initially on cadaver sculls and finally on sedated horses. The digital sensor was not considered viable for this purpose, while the system with image plates and digital developing worked very well. Two different techniques, i.e. parallel and bisectris, are suggested for the best visualization of different parts of the teeth. Intra carious injections of Mixobar oesophaghus contrast fluid was found useful when evaluating the extent of carious lesions. Compared to extra oral radiology, the new method had several advantages and can be used both in clinic and field practices..

Följande litteraturstudie sammanställer information från sex rapporter om hästar med kolik orsakad av spolmask. Särskild tyngdpunkt är ägnad förekomsten av spolmaskassocierad kolik, predilektionsområde för obstruktionen, riskgrupp, riskperiod samt avmaskning i samband med kolikfallen. Detta ämne är synnerligen aktuellt då avmaskningsmedel numera är receptbelagt och en alltmer utbredd läkemedelsresistens mot anthelmintika förekommer. Riskperioden då flest kolikfall inträffar är under hösten och riskåldern är cirka fem månader. Majoriteten av hästarna är avmaskade med ett paralyserande anthemintikum en till fem dagar innan koliken.

The use of a bit in the mouth of a horse is being increasingly questioned with respect to its actual function, and is sometimes judged an obsolete instrument of control with potential to injure the horse. The objective of the research presented herein was twofold; firstly, to investigate the actual pressure load in the mouth of the horse with regard to oral health issues, and, secondly, to investigate whether this could be a viable method to objectively measure strength exerted by a rider/driver to the mouth of the horse especially with regard to training regimes. From the results, it is evident that these newly developed sensors have a future in equine research, although they are still under development. They can be useful both as a pedagogic teaching instrument, providing instructor and pupil with instantaneous, objective feedback on the contact between hand and mouth, as well as an aid in measuring pressure loads from our common bits. .

During the cultivation season there are a several cropping activities to carry out. At what time these activities are carried out is affecting the result and also on the economy of the crop production. As the production costs are high in potato production, it is important to keep an eye on the economy. Profitability is the most important factor in most crop production systems. If the costs are not covered, it is difficult to justify the production.
