Antibiotikaresistens hos bakterier isolerade från friska hundar i Sverige : indikatorbakterier E. coli & Enterococcus spp samt Staphylococcus spp isolerade från hud

Objective: To determine the frequency of antimicrobial resistance in bacteria from healthy Swedish dogs and whether they are carriers of methicillinresistant Staphylococcus aureus (MRSA). Material: Samples from skin from the perineal region and from faeces collected in the anus with cottonswab (Copan) from 299 healthy Swedish dogs. Samples were collected at dog exhibitions. Method: Specimens were submitted for bacterial culture where bacteria (Escherichia coli, enterococci and staphylococci) were isolated and identified by current methods. Antimicrobial susceptibility testing was performed with a microdilution method where MIC-values were determined. Staphylococci with high degree of resistance were tested for presence of mecA-gene by PCR.

Infectious bronchitis in Brazil : a minor field study in Bastos municipality, Sao Paulo

Infectious Bronchitis (IB) is a highly contagious viral respiratory and productiondepressant disease distributed world wide. The disease is caused by the InfectiousBronchitis Virus (IBV), a positive RNA strand Avian Coronavirus within thegenus Gammacoronavirus. Due to a combination of high mutation rate and atendency of recombination a constant emergence of new genotypes and serotypesis seen. In Brazil, a country with an extensive poultry production and majorproblems with disease control, the diversity of circulating strains are wide andoutbreaks of clinical disease despite intensive use of vaccines are common. Theaim of this study was to investigate the presence of IBV and to identify genotypesof isolated IBVs in a limited number of layer flocks in Bastos, São Paulo, as partof the screening for circulating genotypes in the country.

Begomovirus susceptibility in wild Nicaraguan tomato populations

Tomato production is a common and important agricultural activity in Nicaragua. During the last decades tomato producers have suffered great yield losses due to begomoviruses (family Geminiviridae). The genome of begomoviruses generally consists of two circular ssDNA components, DNA-A and DNA-B. Tomato yellow leaf curl virus (TYLCV) is an example of a begomovirus with only one component. An approach to manage the virus epidemics has been to breed a cultivar with begomovirus resistance genes, which have been transferred from wild tomato.

Genome editing with the CRISPR Cas9 system

Rapporten ingår i ett FoU- projekt för Högskolan Dalarna, där målet är att ta fram en konstruktion utan ångspärr som ska klara dagens mått på lufttäthet och fuktkrav.Syftet med denna rapport är att utreda hur fukt påverkar en byggnad medmassivträstomme och olika isoleringsmaterial utan ångspärr. Mineralull och träfiberisolering jämförs mot varandra för att se hur dessa påverkarfuktbelastningen i en väggkonstruktion. Testobjektet är lokaliserat i Dalarna, inget fukttillskott har funnits inomhus i byggnaden.För att genomföra detta arbete har tre stycken olika metoder används. Ensimulering, verkliga uppmätta värden och en provtagning. Fuktsimuleringen genomfördes med hjälp av programmet WUFI, uppmätta värden i form av relativ fuktighet och temperatur har samlats in kontinuerligt under två års tid från väggkonstruktionen via mätsensorer.

Vad är nyttan med en ökad specialisering?

Syftet med detta examensarbete är att undersöka vilken nytta den nya gymnasieutredningens förslag om ökad specialisering och förbättrad anställningsbarhet kan ha för elever inom Hantverksprogrammet ?Textil & Mode . Gällande frågan om bedömningen av en sådan nytta, har fokus i undersökningen i första hand inriktats på vilka krav och önskemål om kompetens som finns inom hantverks- och konfektionsbranschen idag men även i ett framtidsperspektiv. Undersökningen bygger på en kvalitativ forskningsansats med utgångspunkt från ett antal halvstrukturerade intervjuer med olika verksamheter inom hantverk och konfektion. De gene-rella resultaten visar på att kraven för anställningsbarhet inom den mer kvalificerade kärn-verksamheten, ser ut att ligga bortom det grundläggande kunskapsuppdrag som yrkesutbild-ningen inom gymnasiet kan avses ha.

Evaluation of transgenic lines of field pepperweed (Lepidium campestre L.)

The worldwide industrial demand of energy, often in form of fossil fuel, is continuously growing and at the same time these resources are coming to an end (Hamamre, 2013). The interest and focus in renewable sources are then more important than ever and plants are suggested to be a good alternative for production of raw material for industrial purposes (Nilsson et al., 1998). But the world is also facing an increasing world population which also increase the nutritional needs, plants therefore need to be suitable for both industrial and nutritional purposes. To achieve this, common plants need to be improved but it also need new potential crops to be developed and introduced (Carlsson et al., 2009). Modern technology like gene engineering is an important tool to achieve these challenges (Carlsson et al., 2011). This work focused on analyzes and evaluation of different transgenic lines of field pepperweed (Lepidium campestre L.).

Vilken information får hundägare i samband med kastrering av sin hanhund?

BACKGROUND Until 1988, it was forbidden to neuter male dogs in Sweden without a veterinary medical cause, so there is clearly no long tradition of this procedure in healthy dogs. According to the website of The Swedish Kennel Club (SKK), February 11, 2011, there has been an increase of castrated male dogs in Sweden. They see this increase as worrying, especially in cases of the less common breeds, where it is most important to maintain the gene pool. The SKK expresses concern that castration is used as a tool to influence the personality of dogs, instead of training and education of the dog. They write that castration should be preceded by a discussion initiated by the veterinarian, where the pros and cons of castration are weighed against each other.

Bärarskap av meticillinresistent Staphylococcus pseudintermedius (MRSP) hos svenska hundar :

During the last years, meticillin resistant Staphylococcus pseudintermedius (MRSP) have caused an increasing number of infections in Swedish dogs. MRSP is resistant against a majority of the antimicrobials available for dogs in Sweden, making it difficult to treat the infection. Our knowledge of the bacterium is limited, making it hard to handle infected dogs in a proper way. The aim of this study was to investigate for how long time dogs, who have an infection caused by MRSP, become carriers of the bacterium. Other factors like treatment with antimicrobials, the correlation between clinical symptoms and carriage, common diagnoses and institutionalization where also looked upon.

Växtinventering och skötselåtgärder : en studie av Rektorsgårdens trädgård i Uppsala

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.

Genetiska studier på fågelinfluensa :

In the spring of 2006 we had our first outbreak of avian influenza of highly pathogenic H5N1 (HPAI) among wild birds in Sweden. This disease have impact on poultry industries world wide. Sporadically the virus infects other species than birds and we now know it can even cause fatal infection of humans. There are not yet any confirmed cases of transmission of the disease between humans though a suspected case in an Indonesian family is under investigation. If a mutation occurs that changes the pathogenicity and host affinity to humans we are at a risk of a new pandemia, perhaps like the Spanish flu in 1918-1920.

Förekomst av Chlamydia/Chlamydophila spp hos gris med och utan konjunktivit.

ABSTRACTChlamydia and Chlamydophila are species of a family of bacteria (Chlamydiaceae) that cause a range of diseases, including conjunctivitis, in a variety of animals including pigs and humans. Some species cause zoonotic disease. This study examined the occurrence of Chlamydiaceae in samples taken from the lower eyelid conjunctiva in pigs with and without conjunctivitis. The study was initiated based on a herd investigation aimed to examine the experienced increase of conjunctivitis in some finisher herds. This study was conducted as a case-control study, by collecting samples from 62 case pigs (16-26 weeks old) and an equal number of controls, from three herds in Uppland, Sweden.

Importance of epigenetics in animal breeding : genomic imprinting

ABSTRACTThe aim of this study was to give an overview of the evidence for genomic imprinting in livestock and other mammals as well as outline the potential use of gene imprinting in livestock breeding. Epigenetics is the mitotical and meiotical partial hereditary variation in genomic activity without any alterations of the DNA sequence. An example of epigenetic regulation is genomic imprinting where one allele?s expression differs depending on which parent it was inherited from. These parent-of-origin effects are currently overlooked in livestock production.

Koordinering mellan IT-management- och affärsstrategier - En studie inom postorder/distanshandelföretag

I dagens organisationer har man förstått att utvecklingen av teknologin går fort och framåt. För att kun-na hänga med i framåtskridandet måste företag och verksamheter anpassa sig efter utvecklingen som sker i omvärlden för att inte hamna efter. Många företag anser att det inte räcker med bara satsa på af-färsstrategier för att kunna lyckas på marknaden utan behöver också ta fram Informationsteknik-/Informationssystem-strategier som ska stödja affärsstrategierna. Det innebär att kopplingen mellan af-färs- och IT-/IS-strategier är väsentlig på grund av att de är beroende av varandra för att företaget ska lyckas att nå sina mål. Problematik kan uppstå när företag ska koordinera de nämnda strategierna.
