Globally, Campylobacter is the most common cause of bacterial gastroenteritis in humans. Outbreaks of campylobacteriosis have been reported in Sweden in the recent years, despite measures being applied by the poultry industry. Our purpose is to investigate Campylobacter strains from Swedish outbreaks and identify factors that allow these strains to spread and persist in the production chain. Phenotypic characteristics will be defined and compared to non-outbreak strains and coupled to genotypic characteristics to investigate what is behind their success to cause outbreaks in humans. We will investigate tolerance and adaption mechanisms against various stress factors, e.g. dehydration, oxygen and freezing, and the ability to cause infection in human epithelial cells. The findings will contribute scientific knowledge on why certain strains are more likely to cause outbreaks and form recommendations for prevention of Campylobacter in the broiler chicken production.
Infektion orsakad av Campylobacter är den mest rapporterade bakteriella magtarminfektionen i världen. Under åren 2014-2018 hade vi årliga campylobacterutbrott i Sverige under vinterhalvåret. Samtliga av utbrotten visade sig vara kopplade till inhemsk kyckling och ha orsakats av enskilda stammar som spridit sig bland kycklingproducenter, vidare till livsmedel och till slut smittat många människor. Detta projekt ämnar utreda vilka fysiologiska egenskaper som skapar utbrottsstammar av Campylobacter. Egenskaper som t.ex. tolerans mot torka, frysning och syre samt förmåga att anpassa sig och överleva i miljön och att orsaka infektion i humana tarmceller kommer att undersökas. Egenskaper kommer undersökas på DNA och RNA-nivå för att öka förståelsen bakom dem. Förståelsen för vad som tillåter dessa stammar att bli dominerande och överleva genom produktionskedjan kommer användas för att ta fram rekommendationer om kycklinghantering för att förhindra framtida utbrott.

To grow with reduced use of glyphosate is of great concern driven by the requirements for integrated pest management, the risk of herbicide resistance and a potential coming ban on glyphosate. It requires balancing between environmental effects and impact on yield and economy. The project's goal is …

We need to remediate the capacity of agricultural landscapes to retain water, nutrients and sediments to make them
more resilient to the increasing frequency of flooding, drought and pollution expected with the climate change. It can
be done by remediating existing narrow ditches into ditches with …

It is well known that storage of animal manure and digestate causes emissions of methane (CH4), nitrous oxide (N2O) and ammonia (NH3). A crust on liquid manure acts both as a physical barrier for NH3 and as a biofilter that oxidize CH4 and NH3. However, N2O can be formed in some crusts, and there …

Even if Sweden is historically regarded as a water-affluent country, lately sustainable water use and water circularity have become topics of high concern. Irrigation is dependent on high quality water resources, and the need for accessible water resources becomes stronger under exceptionally dry …

An improved strategy for agricultural drainage is important for both economic and environmental reasons. There are indications on environmental benefits of a good drainage but lack of studies that directly shows this. The aim of the project is to develop a basis for design recommendations for new …

The use of safely reclaimed water for agriculture irrigation is a promising solution to address water shortages, especially on Gotland. One primary concern is the introduction of organic micropollutants (OMPs), such as pharmaceuticals and other chemicals, into the agricultural ecosystem and food …

Swedish biogas production is crucial to reach environmental and climate targets and manure represents a great potential, corresponding to ca 2,7 Twh. However, the production from manure-based facilities currently only reaches around ca 64 GWh. Due to the character of manure it is difficult to reach …

Poultry manure is commonly used as fertilizer for crop production, however, high nutrient contents and unbalanced nutrient ratios limit application rates and require larger land areas for spreading, driving up manure handling costs. Techniques for incineration and pyrolysis of biomass are …
