The possible role of transmissible gastroenteritis virus (TGE) and porcine respiratory corona virus (PRCV) in the mortality of Ugandan back-yard piglets

In Uganda, small scale pig production plays a major role for households to earn a living and to secure their access to meat. Piglet mortality due to diar-rhoea-related dieseases is high. In an attempt to understand the underlying causes for this high mortality this study aims to investigate the role of trans-missible gastroenteritis virus (TGEV) and is a part of a larger project con-ducted at Makerere university in Uganda. A complicating factor in this investigation is the porcine respiratory corona-virus (PRCV), a stabile mutant form of the TGE virus. The occurrence of this virus had shown to alter the impact of TGEV in e.g. Europe and North Amer-ica.

Optimization and validation of a triplex real-time PCR assay for thermotolerant Campylobacter species associated with foodborne disease

The genus Campylobacter is globally recognised as the leading bacterial cause of human foodborne gastroenteritis. Every year around 8000 Swedes are infected by Campylobacter. Most people are infected by thermotolerant Campylobacter species, commonly C. jejuni and C. coli.

Sjukdomstillstånd associerade med monocytos hos svenska hundar : en retrospektiv journalstudie

Diseases associated with monocytosis in Swedish dogs - a retrospective study. The purpuse of this retrospective study is to determine which diseases are associated with pronounced monocytosis in Swedish dogs. Records of 153 dogs with monocytosis were evaluated. The most common cause was infectious diseases (49%) of which pyometra was seen in 23% of the cases, cystitis and fever of unknown origin each in 13% and gastroenteritis in 12%. Cortison treatment was the second most common cause with 29%. A sixth of the dogs had non inflammatory diseases such as neoplasia, renal- and heartfailure.

European Food Safety Authority - En studie av legitimitet i en europeisk expertmyndighet

This essay analyses the European Food Safety Authority's (EFSA) legitimacy. Theories on input- and output legitimacy are used in the examination. After analysing stakeholder representation, forum for deliberation, transparency, independence, and information sharing, input legitimacy in EFSA is assessed to be high. Output legitimacy was examined through the authority's outcome effectiveness, which was divided into compliance and effectiveness. Since food safety is an immense area, two important parts were chosen for the analysis of output legitimacy; transmissible/bovine spongiform encephalopathy (TSE/BSE) and genetically modified organisms (GMO).

Prion infection of ovine cell culture with a natural Swedish scrapie isolate from 1986

Scrapie is an infectious neurologic disease in sheep caused by prions, corresponding to transmissible spongiform encephalopathies (TSEs) in other species. The prion is presumably constituted of PrPSc, the misfolded form of the normal endogenous prion protein, PrPC, which is found in practically all cells in the body. PrPSc can induce a conformational change in PrPC and misfold it as an imprint of itself; this is how prions amplify and spread. The process of conformational change is poorly understood and there might exist intermediate forms between PrPC and PrPSc. Bioassay using mice has traditionally been the golden standard in prion studies but is limited by cost and time.

Diseases and causes of death among camelids in Sweden : a retrospective study of necropsy cases 2001-2013

Camelids, especially alpacas, have increased in popularity during the last decade, with the result that they are more frequently encountered by field practicing veterinarians and pathologists. Knowledge regarding their health care and their diseases under Swedish conditions is, however, limited. This became clear in a postal survey among Swedish alpaca owners conducted in 2008. To improve knowledge about camelids in Sweden, this study has examined 107 necropsies, including 93 alpacas and 14 camels, conducted at the National Veterinary Institute (SVA) in Uppsala and at Eurofins in Kristianstad and Skara during the period 2001-2013. The study has shown that camelids in Sweden suffer from diseases similar to those previously reported in other countries in Europe and North America.

Development of real-time RT-PCR for the detection of human sapovirus in foods

Food-poisoning is a major health problem and an estimated half a million Swedes are food-poisoned annually, with acute gastroenteritis as a consequence. One of the major causes of contaminated foods is related to food- and waterborne viruses. To be able to trace back the source of contaminant, the method of detecting viruses must be specific and sensitive. No standardized method for detecting foods for sapovirus exists today. The aim of the work described in this bachelor thesis is to implement and opti-mize a real-time RT-PCR method for the detection of all genogroups of human sapovirus in foods.

Utbrott av livsmedelsburen smitta på äldreboenden i Sverige

Svenskar 65 år eller äldre beräknas öka från dagens 1,6 miljoner till 2,3 miljoner år 2030. Äldre kan ansöka om bistånd vilket kan bestå av matleveranser eller helpension i särskilt boende. Livsmedelssäkerheten styrs av EG-lagstiftning och svensk lag gäller även matleveranser och mat i särskilt boende. Äldre i särskilt boende utgör en högriskgrupp för livsmedelsburen smitta och i dagsläget saknas en information om hur utbrott av livsmedelsburen smitta drabbat äldreboenden. Mot bakgrund av avsaknad av information har detta arbete utförts. En litteratursökning gjordes via ISI Web of Knowledge, sökorden elderly* and food poison* och gastroenteritis and elderly and food användes.

Smittsam cancer hos tasmansk djävul

Detta är en litteraturstudie av sjukdomen Devil Facial Tumour Disease (DFTD) som drabbar tasmansk djävul. De lever i vilt tillstånd på ön Tasmanien som ligger utanför Australiens södra kust. Tasmanska djävular är köttätande pungdjur i ungefär samma storlek som en rödräv. De är nattaktiva och lever ensamma, förutom vid konkurrens om föda och under parningsperioden då de möter andra tasmanska djävular. Vid dessa möten blir det ofta slagsmål för att göra upp rangordningen. DFTD ger stora tumörer i munhåla, ansikte och halsregion samt eventuella metastaser.

Prevalence of antibodies for Peste des petits des ruminants virus and Brucella and related risk factors in goat herds in urban and peri-urban agriculture in Kampala, Uganda

The world?s population reached more than 6.9 billion people in July 2011. It is expected that the population growth during the next 40 years will take place mostly in low-income countries and the population increase will be 2.3 billion people during 2011-2050. A rapid urbanization is also expected to result in 57.7 per cent of Africa?s population living in urban areas in 2050.
