    Som udgangspunkt er det som underviser en gave at få placeret en meget konkret studenteraktiverende aktivitet som et besætningsbesøg er, ind i studieplanen. Der hvor kæden hopper af er at denne tilføjelse ikke betyder, at der tilføres flere ressourcer til planlægning, afvikling og evaluering af denne nye aktivitet. Omdrejningspunktet i min opgave vil da være hvordan kan vi få implementeret besætningsbesøg i fjerkræbesætninger, så hver studerende står med en oplevelse af at de lærer noget om dyrlægers rolle i forbindelse sundhedsstyring og fødevare-/miljøsikkerhedsaspekter i de forskellige typer fjerkræproduktion (slagtekyllinger, æglæggere, opformering, økologi/konventionel mv.) på trods af at hver studerende kun opnår praktisk erfaring med en produktionsform (ca. 60 studerende/besætning) samt meget begrænsede ressourcer

    Draft genome sequences of five clinical <i>Enterococcus cecorum</i> strains isolated from different poultry species in Poland

    Here, we report five draft genome sequences of Enterococcus cecorum strains that were isolated from different bird species of affected poultry flocks (commercial broilers [CB], broiler breeders [BB], commercial layers [CL], ducks [D], and geese [G]) in Poland

    Draft genome sequences of three <i>Escherichia coli </i>strains with different <i>In Vivo</i> pathogenicities in an avian (Ascending) infection model of the oviduct

    Here, we present three draft genome sequences of Escherichia coli strains that experimentally were proven to possess low (strain D2-2), intermediate (Chronic_salp), or high virulence (Cp6salp3) in an avian (ascending) infection model of the oviduct

    Draft genome sequences of two commensal <i>Enterococcus cecorum</i> strains isolated from chickens in Belgium

    Here, we report the draft genome sequences of two commensal Enterococcus cecorum strains (1710s23 and 1711s24), cultivated from the ceca of healthy laying hens originating from different farms in Belgium

    Draft Genome Sequences of Two Avian Pathogenic<i> Escherichia coli </i>Strains of Clinical Importance, E44 and E51

    Avian pathogenic Escherichia coli strains have remarkable impacts on animal welfare and the production economy in the poultry industry worldwide. Here, we present the draft genomes of two isolates from chickens (E44 and E51) obtained from field outbreaks and subsequently investigated for their potential for use in autogenous vaccines for broiler breeders

    BACKGROUND:Infection in the oviduct (salpingitis) is the most common bacterial infection in egg laying hens and is mainly caused by Escherichia coli. The disease is responsible for decreased animal welfare, considerable economic loss as well as a risk of horizontal and vertical transmission of pathogenic E. coli. The outcome of salpingitis may be either acute or chronic. It has not yet been clarified whether the pathological manifestation is a result of the characteristics of the E. coli or whether the manifestation is associated with host factors such as host immunity. RESULTS:From the core- and accessory genome analysis and comparison of 62 E. coli no genetic markers were found to be associated to either acute or chronic infection. Twenty of the 62 genomes harboured at least one antimicrobial resistance gene with resistance against sulfonamides being the most common. The increased serum survival and iron chelating genes iss and iroN were highly prevalent in genomes from both acute and chronic salpingitis. CONCLUSION:Our analysis revealed that no genetic markers could differentiate the E. coli isolated from acute versus chronic salpingitis in egg laying hens. The difference in pathological outcome may be related to other factors such as immunological status, genetics and health of the host. These data indicate that salpingitis is another manifestation of colibacillosis
