  1. 1. Treponema spp. in porcine skin ulcers : clinical aspects

    Författare :Frida Karlsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The hypothesis tested in this work is that bacteria of genus Treponema play a main role when shoulder ulcers and ear necrosis occur in an infectious or severe form, and perhaps also in other skin conditions in the pig. Samples were collected from pigs in 19 Swedish herds 2010-2011. LÄS MER

  3. 2. Treponema spp. in necrotic skin ulcers in pigs : phenotypic and genetic features

    Författare :Olov Svartström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Treponema belongs to the phylum Spirochaetes consisting of bacteria distinguishable by a unique cell architecture that enables corkscrew-like motility. In two case studies, treponemes were isolated from ear necrosis and shoulder ulcers, two types of skin lesions that have impact on animal welfare and may cause economic losses. LÄS MER

  4. 3. In silico analysis of Treponema and Brachyspira genomes : assembly, annotation and phylogeny

    Författare :Mamoona Mushtaq; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Spirochaetal bacteria are highly diverse in terms of life style, growth requirements and virulence, but they all belong to a monophyletic ancient lineage. Many spirochaetes are difficult to culture or have fastidious growth requirements. LÄS MER

  5. 4. Molecular analysis of the oral microbiota of dental diseases

    Författare :Eleni Kanasi; Sirkka Asikainen; Anne CR Tanner; Ingegerd Johansson; Gunnar Dahlén; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; early childhood caries; early periodontitis; 16S rDNA cloning and sequencing; whole genomic DNA probes; oligonucleotide DNA probes; PCR; diversity; molecular; aggregatibacter actinomycetemcomitans; serotypes; Oral microbiology; Oral mikrobiologi;

    Sammanfattning : Traditionally, bacterial culture has been used for bacterial detection, allowing study of living microorganisms. Molecular methods are rapid and allow simultaneous identification of numerous species and uncultivated phylotypes. LÄS MER

  7. 5. Dichelobacter nodosus and footrot in Swedish sheep : increased knowledge and improved laboratory diagnostics

    Författare :Sara Frosth; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Ovine footrot is a contagious bacterial disease primarily caused by Dichelobacter nodosus. Footrot affects the feet of sheep and is characterised by two major clinical presentations. LÄS MER
