Salmonella är en bakterie som skapar klinisk sjukdom hos människa och djur. Jag har valt att studera hur salmonellos manifesterar sig kliniskt hos katt, hur katten smittas, vad prevalensen för Salmonella är i olika kattpopulationer, huruvida det finns en risk att denna smitta överförs till människor samt vilka åtgärder som kan vidtas för att undvika smitta.De kliniska symtomen på salmonellos hos katt varierar stort, från gastroenterit med symtom som feber, kräkningar och sekretorisk diarré, till symtom som letargi, pneumoni, epistaxis, endotoxinemi och konjunktivit med avsaknad av gastrointestinala symtom. Katten kan smittas genom kontakt med andra katter eller deras Faeces, genom kontaminerad miljö, jakt av vilda fåglar, intag av icke upphettat foder eller transplacentalt. Då prevalensen bland katter varierar beroende på undersökning krävs fler studier för att kunna dra slutsatser avseende utbredningen i den svenska kattpopulationen.Ett flertal studier visar på omständigheter som starkt tyder på att en zoonotisk potential föreligger. Fall där Salmonella-smitta har gått från katt till människa redovisas också.

Bakgrund: Förstoppning är ett av de vanligaste symtomen från mag- och tarmkanalen och att drabbas av förstoppning kan vara en hemsk upplevelse. Tillståndet påverkar personen både fysiskt, mental, socialt och existentiellt, vilket leder till försämrad livskvalité. Syfte: Att beskriva vilka icke-farmakologiska åtgärder som finns för att förebygga förstoppning hos äldre personer över 65 år. Metod: Studien genomfördes som en allmän litteraturstudie där vetenskapliga artiklar söktes i databaser på Internet och manuellt i referenslistor. Åtta vetenskapliga artiklar inkluderades i studien och dessa analyserades och utformades till ett resultat.

The cattle production in the world has been questioned in Sweden due to its negative impacts on the environment. The use of imported soya bean meal as a protein feed for Swedish cattle results in the cutting of rainforest and an extensive use of pesticides in the countries were the soya beans are produced. As a consequence, the environmental impacts caused by cattle production increases. A production of protein feeds in Sweden would decrease the transportations and the cutting of rainforest. For organic beef producers the possibility to produce home-grown protein feeds is important since organic protein feeds can be difficult to obtain in another way.

Magnesium is one of the most important minerals in the body and it participates in many essential processes, such as energy metabolism and protein synthezis. Magnesium deficiency in cattle may occur when they are let out for pasture in the spring, and is associated with tetany, known as grass staggers. A high yielding dairy cow often loses more magnesium daily in the milk than she has available in the body, and magnesium thereby needs to be provided in the feed to prevent the cow from being affected by deficiency symptoms. The uptake of magnesium is mainly located to the rumen and is not regulated by hormones. The surplus is excreted in the urine by the kidneys.

This report includes common helminths, symtoms, routes of infection, diagnostic laboratory techniques and prophylactic methods to prevent infection. We have pointed out where there is a risk of zoonotic transmission and how to avoid contamination and infection. We have restricted the number of species to the most common helminths. Some of these helminths do not naturally occur in Sweden (yet) but are nevertheless of current interest when we travel across borders with our horses, dogs and cats. The diagnostic part of our report tells about different techniques to find an occurance of helminths in samples of Faeces, blood, urine or saliva from a horse, dog or cat. We also write about some recommendations on treating parasitic infections and the development of anthelmintic resistant helminths that originates from incorrect use of anthelmintic drugs .

The aim of this study was to isolate and identify Lactobacillus species indigenous to the gastrointestinal microflora of Swedish horses. These lactobacilli are to be used as probiotic candidates in research concerning antibiotic-associated diarrhoea in horses. Eight horses, age 6-10 years, were selected from a riding school for collection of Faeces samples. Man Rogosa Sharp medium and gram staining were used for the selection of supposed lactobacilli. We could identify 33 isolates of supposed lactobacilli. With the use of API tests 22 of these 33 isolates could be identified.

This paper shortly describes the coronavirus family, bovine corona viruses (BCV) properties and two diseases that BCV causes, winter dysentery and calf diarrhoea. The purpose of the study was to compare different diagnostic methods to detect BCV. Different methods are discussed, PCR, ELISA, immunofluorescense and virus isolation. Investigations were made in three different herds with winter dysentery; one dairy cattle farm with about 100 cows of different ages, one testing station for bulls with about 150 bulls and another small dairy cattle farm with 26 cows and 20 replacement heifers and calves. Faeces and nasal swabs were analysed with PCR and ELISA. The result shows that PCR seems to be a reliable method for detecting BCV but that the ELISA test can not be used as a reliable diagnostic method to analyse samples from animals with winter dysentery..

American bison (Bison bison bison) is a new species in Sweden and was introduced in the year 2000. In this study the result of an interview and a field investigation is presented. The aim was to investigate the health and parasite status in Swedish bison herds. The most common reason to begin with bison breeding was meat production and/or sale of breeding animals and tourism. The Swedish breeder?s experience of bison is that they in general are healthy.

Psittacos eller papegojsjuka är en zoonotisk sjukdom som främst drabbar fåglar, men i mindre omfattning även däggdjur. Sjukdomen orsakas av den obligat intracellulära bakterien Chlamydophila psittaci.Smittade fåglar utsöndrar bakterien i framför allt Faeces och nässekret. Utsöndringen är ofta intermittent och kan sättas igång av stress. Både fåglar och människor får framför allt i sig bakterien genom inhalation av aerosoler eller damm, men även oral och kontaktsmitta är möjlig.Symptombilden är varierande hos både fåglar och människor. Ofta ses en subklinisk eller mild sjukdom med diffusa symptom, såsom feber, apati, konjunktivit och milda respiratoriska symptom.

In the report parasites in the gastrointestinal tract and easily visible external symptoms of disease in capercaillie, (Tetrao urogallus), was taken into account. The study was based on results from the examination of 62 fresh faecal samples, collected in spring 2003, and postmortem examination of 22 frozen birds that were collected between 1999 and 2003. All of the samples principally were from the north of Sweden. In total, 4 species of parasites, but no significant symptoms of disease were found. In the Faeces low levels eggs of the roundworms Capillaria spp. (125 epg) and Ascaridia spp.

Helicobacter är en gramnegativ, mikroaerofil, ureas-positiv, skruvformad bakterie som hittas i mag-tarmkanalen, saliv och Faeces. Helicobacter pylori orsakar hos människor gastrointestinala sjukdomar, cancer och försvagning av immunsystemet. År 1988 isolerades den första skruvformade bakterien från katt och 1991 fick den namnet Helicobacter felis. De vanligaste arterna hos katt är Helicobacter felis och Helicobacter heilmannii. Mycket av forskningen idag görs för att fastställa patogenesen och för att undersöka om det finns någon zoonosrisk avseende överföring av Helicobacter species från katt till människa eller vice versa.

The common warthog (Phachocoerus africanus) is a relatively long-legged pig with noticeable curved tusks, a short neck and three pairs of facial warts. It has four recognized subspecies. The common warthog is a non-migratory ungulate living on the African savannah. It is a hindgut fermenter and predominantly dependent on high-quality foods. It prefers open areas for grazing but use bushes for cover.

Endektociden ivermektin används i stor omfattning inom veterinärmedicinen. Läkemedlet metaboliseras i låg grad och kommer ut som verksamt ämne i Faeces och utövar sina effekter på andra än målorganismerna, bl.a. Faeceslevande arter. Eftersom vissa vattenlevande organismer uppvisar en särskild känslighet kommer denna litteraturstudie att fokusera på ivermektins toxicitet på organismer i akvatisk miljö och huruvida dessa kan vara i fara i svenska vatten. Daphnia magna är den art som visat sig känsligast och effekter har setts på nivåer så låga som 0,001 ng/l. Ivermektin verkar vara särskilt toxiskt för cladoceraner, den ordning som D.

Safe retrieval of nutrients from human excreta to fertilize crops in order to gain adequate yields will increase food security and sustainability in agriculture areas with nutrient-poor fields. Safe and nutritious food will meet the dietary needs of the individual which promotes public health and the ability of an active life. Human excreta should be considered as a resource instead of being assumed as waste. Human Faeces and urine is excellent fertilizers which may close the nutrient loop if utilized properly. However, sanitation of the excreta is required to prevent disease transmission by reducing the content of gastrointestinal pathogens such as bacteria, viruses and parasites. The objective of this study was to in small scale evaluate the sanitation in a combined liquid compost and urea treatment by monitor the inactivation of bacteria and viruses at the combination three start temperatures, 45, 40 and 35 °C, and three additions of urea, 0.5, 0.75 and 1 % and reference, 0 % urea addition.

Working horses in developing countries are mostly used for transportation. They are often owned by people with limited economical resources and lack of knowledge about how to take care of the horses and due to this the horses often suffer from problems such as dehydration, poor body condition, lesions and parasitic infections. The aim of this master thesis was to investigate if free veterinary care improved the health and hydration status of working horses in Nicaragua and it was performed as a part of a project called ?Free veterinary assistance for working horses and training of their owners as veterinary promoters in the Pacific coast of Nicaragua?. Five parameters were used to investigate whether free care improved the health of working horses in six towns along the Pacific Coast of Nicaragua.
