Drinking water is produced from raw water and is either from groundwater or surface water. This thesis aims to find out if the cleaning process of raw water is sufficiently effective. This is important because consumers are otherwise at risk of waterborne infection caused by pathogens. There are three groups of pathogens; bacteria, virus and parasite. These have different characteristics which mean that they require different water treatment to be separated.

Obese horses with insulin resistance are often also afflicted with laminitis. Horses with these symptoms are given the diagnosis equine metabolic syndrome (EMS). Signs of insulin resistance are excessive accumulation of adipose tissue on the neck, around the withers and on the dorsal area of the hindquarters. Insulin resistance means that the function of insulin is defective and does not stimulate glucose uptake by the cells in the body in the correct way. This will result in an increased insulin release.

Anthelmintic resistance is a major problem in sheep husbandry all over the world. One way toslow down the development of anthelmintic resistance is to keep part of the parasitepopulation in refugia (unexposed to drugs) which will maintain the genes for susceptibilitywithin the population. Climate, type of parasite and drenching regimes effect the size of therefugia. Dilution of resistant with susceptible parasites, targeted treatment and targetedselective treatment are all management strategies that employ refugia. Dilution is possible butcomplicated.

Rotavirus causes diarrhea in young mammals all over the world, including infant humans. The diarrhea leads to severe dehydration that can be fatal if left untreated. The dehydration can be treated with fluid therapy and the infection heals itself. Despite the relatively easy treatment half a million children under the age of five dies every year due to diarrhea caused by rotavirus. Rotavirus sorts into the family Reoviridae and is a double-stranded RNA virus with a segmented genome.

Equestrianism is a big sport in Sweden with many practitioners. It is a dangerous sport and it is important for the rider to be aware of the risks, to study equine ethology and know how to handle the horse, to avoid accidents. Today most people have their first contact with a horse through a horseback riding school. Ölmstad rid- och körsällskap is a riding school that provides their pupils with a different kind of lessons. The lessons are 90 minutes long and contain both riding and horse-knowledge education.

Multiple Congenital Ocular Anomalities (MCOA) is a genetic disease that affects primarily Silver coloured horses of breeds such as the Rocky and Kentucky mountain horses. In these breeds the Silver dapple colour is very popular leading to an increase of affected horses. The major feature of the disease is ocular cysts of variable size. Large cysts also lead to a variety of secondary syndromes, for example retinal detachment. In previous studies the locus for MCOA has been mapped to an interval of 420 kb on equine chromosome six.

etta arbete belyser det för hästnäringen stora problemet ekvina placentiter från en veterinärmedicinsk synvinkel. Ekvin placentit betyder moderkaksinflammation hos häst. De vanligaste orsakande virusen, EHV-1 och EVA, samt ett mykotiskt agens, Histoplasma, tas upp. Bakteriella placentiter är dock mycket oftare förekommande. Därför diskuteras inte bara de tre agens som är vanligast; Streptococcus zooepidemicus, Escherichia coli och Pseudomonas aeruginosa, utan även två bakteriella agens på snabb frammarsch; Leptospira spp.

The most common reason for a horse owner to seek veterinary care for their horse is related to the musculoskeletal system. Assessment of the horse's movement pattern is essential in the equine veterinary work. How uniformly veterinarians evaluate the lame horse may have both diagnostic and prognostic significance, such as follow up examination by the same or different veterinarian. The purpose of this study was to evaluate whether there are between-veterinarian differences in assessing lameness in the same horse. In total 12 veterinarians evaluated 80 video sequences of 4 horses with induced lameness and made an evaluation of the affected limb as well as the degree of lameness.

Opioids are considered the "golden standard" in pain management for both humans and small animals, but is used less often in equine medicine - probably for fear of side effects. Are there any studies that suggest that side effects are a major problem, or is it lack of experience which is the greatest obstacle to use? As early as 1937 it was shown that morphine and morphine derivatives provide analgesia in horses. For species other than horses used opioids often both pre-, intra-and postoperatively. They relieve pain effectively and are often included in the anesthesia protocol.

Det finns många olika typer av bromerade flamskyddsmedel. De är alla stabila i miljön men graden av toxicitet och bioackumulering varierar. Att bromerade flamskyddsmedel är endokrinstörande är känt men min hypotes är att de även är neurotoxiska och att de kan orsaka neurologiska störningar hos människa. Människor exponeras för bromerade flamskyddsmedel via damm och föda. Barn och foster som är känsligare än vuxna kan även exponeras via modersmjölk respektive placenta. Barn har högre serumkoncentrationer av bromerade flamskyddsmedel än vuxna.

Horses are herbivores that spend almost all day grazing. While grazing they are infected by different endoparasites through ingestion of infective eggs or larvae on pasture. The most significant equine endoparasites in Sweden are the equine roundworm Parascaris equorum, small (Cyathostominae) and large strongyles (Strongylus spp), the tapeworm Anoplocephala perfoliata and the pinworm Oxyuris equi. For many years have horses been dewormed on regularly basis, which has resulted in the development of resistance to many anthelmintic classes. Because of the problems with resistance it is since 2007 necessary to have a prescription on anthelmintics and faecal sampling is also recommended.

Summary:The Clinical Training Center at the Swedish University of Agricultural Sciences in Uppsala uses new methods for educating and training veterinary students. Among these methods are computer programs. The aim of this study was to create an interactive application based on data from horses CT-scanned at the Center for Medical Image and Visualization at Linköping University Hospital. The purpose of this application is for veterinary students to be able to use multidimensional visualization to study equine anatomy. The resulting application named "EQUINE VIRTUAL ANATOMY - Flash in the Tunnel" consists of data from six heads, one left foreleg and a wooden dalahorse.
