The sterol content of cellular lipids of Treponema hyodysenteriae, the agent of swine dysentery, was determined. When cultured in lipid-depleted brain heart infusion broth containing vesicles made Author: Thad Stanton. Studies on strains of Mycoplasma capricolum subsp. capripneumoniae isolated from outbreaks of contagious caprine pleuropneumonia in Eritrea Article in Small Ruminant Research 45(2) The interaction between Treponema hyodysenteriae and isolated swine intestinal epithelial cells or mouse adrenal cells in culture was examined. Studies were performed in which treponemes were incubated with each type of animal cell in an atmosphere of 5% CO 2 in air. Coincubation was terminated at various time intervals, and the percentage of treponemal attachment evaluated by light microscopy.   From 10 days before the expected date of farrowing onwards, 97 sows infected by Mycoplasma hyopneumoniae and Treponema hyodysenteriae were given tiamulin daily at a dosage of 20 mg/kg bodyweight via the feed. Three days before farrowing the sows were washed with a disinfectant and transferred to an isolated farrowing house. The sucking piglets remained with their dams for five Cited by: 4.

The aims of the current study were to collect intestinal spirochaetes (genus Brachyspira) from farmed and wild mallards (Anas platyrhynchos) and to identify and classify those isolates that phenotypically resembled Brachyspira hyodysenteriae, an enteric pathogen of pigs. The isolation rate of Brachyspira spp. was high from both farmed (93 %) and wild mallards (78 %).Cited by: back of the book lists each major disease by name, often cross-referenced with a synonymous name. A section on exotic (foreign to the US) diseases is provided for ready reference. Any of these diseases may be introduced to the US as a consequence of international trade in .

Serpulina (Treponema) hyodysenteriae, an anaerobic beta hemolytic spirochaete, is the etiologic agent of swine much is known at present about the virulence factors of S. r, the hemolysin production of this bacterium is generally accepted to Cited by: In the mids, two models of mycoplasma evolution were proposed. The first model considered that mycoplasmas were polyphyletic and had arisen by degenerate evolution and diversification of different bacterial lineages, with different mycoplasmas originating from different branches of the bacterial phylogenetic tree. The second model was that mycoplasmas arose very early in the evolution of Cited by: 1.   The nucleotide sequence of the Brachyspira hyodysenteriae ftnA gene, encoding a putative ferritin protein (FtnA), was determined. Analysis of the sequence predicted that this gene encoded a protein of amino acids. RT-PCR and Western blot showed that the ftnA gene was expressed in B. hyodysenteriae, and evidence suggests that FtnA stores iron rather than haem. ftnA Cited by: Taxonomy. The genus Brachyspira is within the order Brachyspirales and was recognized as a genus distinct from Treponema in (Hovind-Hougen et al. ; Gupta et al. ; Oren and Garrity ).There are currently 7 species with standing in the nomenclature: Brachyspira hyodysenteriae, B. pilosicoli, B. murdochii, B. innocens, B. intermedia, B. aalborgi, and B. alvinipulli (Euzéby Cited by: 4.
