We have recently reported that three distinct size- and phase-variable surface lipoproteins (Vsps) of the bovine pathogen Mycoplasma bovis possess a common epitope recognized by monoclonal antibody 1E5. In the present study, we show that this epitope is also present on a size-variant protein (PvpA) of the avian pathogen Mycoplasma gallisepticum. Application(More)
The examination of acute or chronically altered phallus-tissues of ganders revealed microorganisms belonging to the genera Mycoplasma, Bacteroides, Clostridium, Streptococcus, Micrococcus, Staphylococcus, Lactobacillus, Corynebacterium, Escherichia, Campylobacter, Proteus, Pseudomonas and Candida and to the family Pasteurellaceae, isolated in different(More)
Between 1982 and 1985 the cadavers of 50 Guillemots (Uria aalge), 41 Kittiwakes (Rissa tridactyla), 26 Herring Gulls (Larus argentatus) and 34 Black-headed Gulls (Larus ridibundus) were examined pathological, bacteriological and virological. The probable cause of death was established. Parasitosis were particularly prevalent in Herring Gulls (49%), where(More)
Salmonella Enteritidis emerged as a major egg-associated pathogen in the late 20th century. Epidemiologic data from England, Wales, and the United States indicate that S. Enteritidis filled the ecologic niche vacated by eradication of S. Gallinarum from poultry, leading to an epidemic increase in human infections. We tested this hypothesis by retrospective(More)
Twenty-four strains isolated mainly from infected respiratory tracts of pigeons were characterized by an integrated genotypic and phenotypic approach. An extensive biochemical examination using conventional tests and several API microtest systems indicated that all isolates formed a phenotypically homogeneous taxon with a DNA G + C content between 42 and 43(More)
Ten strains recognized on the basis of a computer-assisted numerical comparison of whole-cell protein patterns as members of a novel species belonging to the family Alcaligenaceae were examined by using an integrated phenotypic and genotypic approach. This species, for which we propose the name Bordetella trematum sp. nov., was more closely related to the(More)
Taxon 1502 was originally described as a Riemerella anatipestifer-like bacterium causing exudative septicaemia in ducks and geese. In the present study, an integrated genotypic and phenotypic approach was used to elucidate the phylogenetic affiliation and taxonomic relationships of 12 strains of taxon 1502. Whole-cell protein and fatty acid analyses and an(More)
Seven Vibrio-like field strains of German origin were isolated culturally from diseased domesticated ducks, muscovy ducks and geese, and were compared with reference strains NCTC 8443 (type strain) and NCTC 11170 of Vibrio metschnicovii using classical phenotypic and chemotaxonomic tests. Some V. cholerae strains were included in the chemotaxonomic tests(More)
The phylogenetic position of the causative agent of septicemia anserum exsudativa, now most often referred to as [Moraxella] anatipestifer (brackets indicate a generically misnamed taxon) or "[Pasteurella] anatipestifer," was established by performing rRNA cistron similarity studies. [Moraxella] anatipestifer belongs to rRNA superfamily V, together with the(More)
The outbreak of the disease occurred in a large multiple-age farm with about 50,000 meat turkeys, where groups of 6-8000 one-day-old birds were stalled up every 14 days. All the turkey poults housed were affected mostly in the 1.-3. week of the life. The respiratory disease spread rapidly within the flocks and were characterised clinically by inclination of(More)
