Resandet mellan länder ökar allt mer och många resor går från rikare till fattigare länder i tropiska och subtropiska områden. De resande möter ett annat panorama av sjukdomar än i hemlandet och det vanligaste hälsoproblemet bland resenärer är turistdiarré. Inför resan söker många råd på en vaccinationsmottagning. Råd ges bland annat kring kost och vaccin för att förhindra turistdiarré. Syftet med studien var att undersöka det vetenskapliga underlaget för att sjuksköterskor skall kunna ge evidensbaserade råd kring kosthållning och vaccination för att undvika turistdiarré.

Kastrering av smågris för att motverka galtlukt görs idag i Sverige under grisens första levnadsvecka utan bedövning. EU kommissionen har lagt fram ett förslag på att från och med 2012 ska all kastrering av grisar ske med bedövning, och kirurgisk kastrering ska upphöra från 2018 under förutsättning att vissa praktiska problem har lösts tills dess. Olika alternativ till dagens kastrering är således ett mycket aktuellt problem och ett av alternativen till detta är immunokastrering. Immunokastrering sker genom att man vaccinerar grisen mot ett endogent hormon, GnRH (gonadotropin releasing hormone), vilket hämnar testikelns funktion och minskar bildning av galtluktsämnena androstenon, skatol och indol. Denna litteraturstudie är inriktad på hur immunokastrering påverkar grisarna ur produktionssynpunkt med fokus på kött- och fetthalt, beteende, foderåtgång och andra problem som diskuteras kring den praktiska tillämpningen av immunokastrering på gris i Sverige. Studien visar att immunokastrerade grisar har högre kötthalt, lägre fetthalt och mindre foderåtgång än kirurgiskt kastrerade grisar.

Virulent strains of Staphylococcus hyicus produce exfoliative toxins and cause a potentially fatal skin disease in piglets known as exudative epidermitis. Vaccines and antimicrobials are used to control the disease. Antimicrobial resistance and the prevalence of several different toxin genes and toxigenic strains make it problematic. The aim of this literature study was to identify potential differences between countries and between healthy and diseased pigs regarding antimicrobial resistance and toxin-producing strains. Great differences could influence vaccine production, treatment strategies and surveillance programs.

African Swine Fever (ASF) is one of the most serious transboundary swine diseases because of its high lethality for pigs, socioeconomic consequences, rapid and international spread and the absence of either treatment or vaccine. This Sida Minor Field Study (MFS) was carried out during fall 2010, as part of a larger collaborative research project called ASFUganda, focusing on the epidemiology of the disease in Uganda. The aim with this study was to get more knowledge about the pathology in cases of ASF in Uganda, by studying macroscopic and microscopic lesions in pigs with acute and chronic ASF and to detect the ASF virus (ASFV) in tissues by immunohistochemistry. The pigs were selected from the two different geographical locations in Uganda, Mityana and Gulu district, both with on going confirmed outbreaks of ASF. Necropsies were performed in the field, and the laboratory procedures at the JICA (Japan International Cooperation Agency) Veterinary Pathology Laboratory, Entebbe, Uganda, and at the Department of BVF, SLU, Uppsala, Sweden. Three pigs from an outbreak of ASF in Mityana district showed both the history and the clinical symptoms typical for ASF.

The presence of cystic ovarian follicles represents an important ovarian dysfunction and is a major cause of reproductive failure in dairy cattle. A cystic ovarian follicle is a persistent follicular-like structure on one or both of the ovaries. It is at least 2,5cm in diameter and it has to persist for at least ten days while a corpus luteum is missing. There are two kinds of cystic ovarian follicles, those who have a progesterone production and those who have not. A clear definition for this condition is lacking, probably because the heterogeneity of the clinical signs and the complexity of the disorder.

ABSTRACT. Introduction: Human Immunodeficiency Virus (HIV) is a retrovirus which occurs worldwide and spreads between humans mainly through sex, from mother to child, blood and blood products and between injecting drug users. After been infected with HIV for a couple of years the final stage of the infection progress into Acquired Immune Deficiency Syndrome (AIDS), and there is no cure or vaccine, only medication that delays the development of the disease. Objective: The aim of this thesis is to examine the preventive work against HIV in Sweden, the groups at risk for getting infected and to highlight sexual attitudes and behaviours among adolescents and young adults. Method: A literature based study method was used and the material is based on scientific articles and reports from active actors within the field of HIV prevention.

Bakgrund: Sedan januari 2010 ingår vaccin mot humant papillomvirus i det svenska barnvaccinationsprogrammet. Beslutet att vaccinera eller inte vaccinera sina barn kan vara svårt för föräldrar. Syfte: Var att beskriva föräldrars kunskap om och attityd till vaccin mot humant papillomvirus och hur det inverkar på deras beslut att vaccinera sina barn. Design: Mixed-methods research integrated design. Metod: Beskrivande litteraturstudie.

In 2012, about 1.3 million boars were surgically castrated, most of them without anaesthesia. Castration is performed to avoid the occurrence of boar taint and aggressive and sexual behaviour. There is a growing concern about the welfare of the piglets and the Swedish Board of Agriculture is working to find efficient and functional alternatives to castration without anaesthesia. The aim of this study was to obtain an overall picture of the latest research about the alternatives to castration without anaesthesia, with focus on vaccination against boar taint, and how they affect the welfare of the pigs. The alternative methods that are available today are surgical castration with anaesthesia and/or analgesia, rearing entire males and vaccination against boar taint.

The Bovine respiratory syncytial virus (BRSV) causes bronchiolitis and interstitial pneumonia, predominantly in calves, and is a major cause of bovine respiratory disease worldwide. In humans, BRSV is paralleled by the closely related Human respiratory syncytial virus (HRSV), an important cause of respiratory disease, most severe in infants.The clinical signs and pathology during RSV infection is caused, not only by the direct effects of viral replication, but also by the response of the host immune system. The immunopathology of RSV has long obfuscated our understanding of the disease, and development of effective treatment and vaccines will be very difficult until greater knowledge is gained.One of the components of the immune system that has come into focus in RSV research the last few years, is the Toll-like receptor 4 (TLR4). The TLR4 receptor is well known as the receptor that binds lipopolysaccaride (LPS), and initiates the host response to bacterial infection. Recently, it has been shown that the fusion protein of RSV also interacts with, and up-regulates the expression of, the TLR4 receptor.

The demand for animal products has increased in the last decades, especially for poultry and pork. Pork production has increased drastically globally, and also in Uganda. Thirty-one percent of Uganda´s population lives in poverty. Pig production is believed to play a crucial role in poverty alleviation, because of the ability to convert low quality feed into high quality protein together with high reproductive potential. African swine fever (ASF) is a lethal disease of domestic pigs often characterized by haemorrhagic fever and with mortality rates up to 100%. The disease is endemic in most sub-Saharan countries and since 2007 in the Russian Federation and Caucasus area.

Vaccination of fish can be assumed to cause pain. This study was designed to see if we can minimize the suffering of fish following vaccination. Fishes are cold-blooded animals and thus more primitive than warm-blooded animals. Despite this, many organs, e.g. the nervous system, have the same basic structure as that of other vertebrates. The fibre system for conducting pain is more diffuse than in humans.

We live in an exciting society, characterized by continuous changes and challenges. The effects of the globalization are widespread. The continuous flow of people, capital and goods follows in the wake of advances in communications, transport and information technology, resulting in a changed situation for different stakeholders in the society. This situation leads to increased cooperation and exchange, but also increased competition. The primary means of collecting empirical data for this study was interviews and a document study.

Papillomvirus är ett cirkulärt naket dubbelsträngat DNA-virus som kan orsaka benigna eller maligna transformationer i epitel på de allra flesta djur. Olika djurslag har olika artspecifika papillomvirus. Viruset sprids via direkt- eller indirekt kontakt. Hos människa finns över 100 olika typer av humant papillomvirus (HPV) som har olika predilektionsställen på kroppen. Cirka 40 av dem angriper anogenitala områden där vissa kan ge upphov till könsvårtor medan andra ger cellförändringar som senare kan utvecklas till cancer. Hos kvinnor är slemhinnan i cervix känslig för onkogena HPV och cellförändringar där kan leda till cervixcancer (CC).

ABSTRACT. Mastitis is one of the most common diseases affecting dairy cows worldwide. In Sweden annu-ally about 60% of the dairy cows get infected and Staphylococcus aureus cause approximately 30% of these infections. Mastitis causes enormous economic losses. In Sweden, the costs to cure mastitis are estimated to be 192 million SEK per year, excluding the costs for mastitis prevention.
