actinomyces hordeovulneris, a canine pathogen that produces l-phase variants spontaneously with coincident calcium deposition.the spontaneous production of cell-wall-deficient filaments and protoplasts by a strain of actinomyces hordeovulneris (ucd 81-332-9) in 10% sucrose l-form media is reported. multiple mineral deposits were present within the variants at 48 hours. electron microscopy revealed that these deposits were amorphous, dense, and at the inner face of the cytoplasmic membrane in wall-less protoplasts and also in filaments which had a thin wall of 10 nm. these cell-wall-deficient variants produced l-form co ...19846524750
actinomycosis of dogs caused by actinomyces hordeovulneris.actinomyces hordeovulneris was isolated from the lesions of chronic pyogranulomatous pleuritis and pericarditis of one of three dogs showing similar symptoms. the parietal pleura and the pericardium were thickened and covered with fine short threads of angiofibroblastic tissue. about 500-1000 ml of reddish purulent exudate in the thorax of all three dogs contained large numbers of rice-grain-sized, soft, yellowish-white granules ("sulphur granules"). these granules had a central core of branchin ...200010906260
