Colibacillosis is a common disease in poultry and includes both local and systemic infections. Increased knowledge is necessary for development of effective methods to prevent disease, such as improved management routines, modification of environment, and vaccine development. The first study (WP1) has an epidemiological focus with risk analysis by in-depth studies of farms with healthy birds and poultry diagnosed with colibacillosis. Samples will be collected (WP2) for isolation of pathogenic (APEC) and commensal E. coli. Whole genome sequencing (WP3) will enable comparison of strains, identification of specific virulence factors and detection of antibiotic resistance genes. Antimicrobial susceptibility testing will be performed to examine possible links between APEC and resistance (WP4). The results will contribute to new knowledge regarding risk factors for outbreaks, control methods, and the industry's ability to prevent and treat outbreaks of colibacillosis in a sustainable way.
Kolibacillos är en vanlig infektionssjukdom hos fjäderfä som kan orsaka såväl lokal som allmän infektion. Ökad kunskap är nödvändigt för utveckla effektiva metoder att förebygga och bekämpa sjukdomen. Möjliga åtgärder kan vara förbättrade skötselrutiner, åtgärder i närmiljön, och framtagande av vaccin. Första delstudien (WP1) har epidemiologisk inriktning med riskanalys och djupstudier av besättningar med friska och sjuka fjäderfä. Vid besättningsbesök tas prov (WP2) för att samla sjukdomsframkallande (APEC) och vanligt förekommande E. coli. Bakterierna helgenomsekvenseras för att jämföra arvsmassa och studera förekomst av specifika sjukdomsframkallande egenskaper och antibiotikaresistensgener (WP3). Resistensundersökning kommer att göras för att undersöka eventuella samband mellan APEC och resistens (WP4). Syftet är att bidra till ny insikt om bakomliggande orsaker och möjliggöra framtagande av kontrollmetoder för att förebygga och bekämpa utbrott av kolibacillos på ett hållbart sätt.

All horses grazing freely are at risk of parasitic diseases. Due to a growing problem with drug resistance in parasites, there is a need to improve the diagnostic methods. One important problem with today's situation is that one diagnostic procedure costs significantly more than one treatment, both …
