“…, 2002]. Acholeplasma is a widely distributed mycoplasma in nature and possesses very versatile adaptation capabilities [Chernov et al, 2005]. Among all its ecological capabilities, it is a causative agent of some plant diseases [Chernov et al, 2007[Chernov et al, , 2011.…”

Organic wastes, such as cow manure, are often composted with earthworms (vermicomposting) while excess water is drained and collected. This wormbed leachate is nutrient-rich and it has been extensively used to fertilize plants. However, it is derived partially from a not yet finished compost process and could exhibit phytotoxicity or contain potentially hazardous microorganisms. The bacterial community in wormbed leachate derived from vermicomposting of cow manure was studied by pyrosequencing the 16S rRNA gene. The fresh wormbed leachate was rich in Mollicutes, particularly the genus Acholeplasma which contain phytopathogen species. The abundance of the Mollicutes decreased when the leachate was stored, while that of the Rhizobiales and the genus Pseudomonas increased. The bacterial communities changed rapidly in the leachate during storage. The changes in ammonium, nitrate and inorganic carbon content of the wormbed leachate when stored were correlated to changes in the bacterial community structure. It was found that storage of the wormbed leachate might be required before it can be applied to crops as large proportions of potentially plant pathogens were found in the fresh leachate.

Summary: First comparative analysis for some hemocoagulation reactions, immune state of acute myocardial infarction has been done in two groups of patients -with mycoplasma infections and without one. Postinfarction complications in the groups were observed. Atherosclerotic plaques of the patients were also studied on a presence of mycoplasmas and a content of strontium and zinc. A tendency to a mild pattern of acute myocardial infarction was observed in patients with mycoplasma infections. The role of mycoplasmas in atherogenesis and acute myocardial infarction is discussed.

“…The mycoplasma cells were grown for 22-24 h in a liquid modified Edward's medium. The complete medium contained the following components (%): tryptose, 2; NaCl, 0.5; KCl, 0.13; Tris, 0.3; horse blood serum, 10; yeast extract, 5; glucose, 1; penicillin, 1000 U/ml; and phenol red, 0.3 ml of 1% solution [1]. Glucose, yeast extract, and serum were excluded in case of UFE (starvation).…”

“…To adapt A. laidlawii PG8 to the unfavorable growth conditions, the cells were harvested at the logarithmic growth stage (22)(23)(24) h at 37°C), stored for 2 h at 8°C, collected by centrifugation (4500 ×g, 8°C, 20 min), resuspended in four volumes of the limited medium, and then stored at 30°C for 8 weeks. A. laidlawii PG8 cells grown in the limited medium -adapted to UFE -, while grown in the Edward's medium -unadapted to UFE -were of control one [1]. Investigations were performed for A. laidlawii PG8 cells of 22-24 h (exponential phase growth) in case of unadapted culture and of 8 weeks in case of adapted to UFE mycoplasma.…”
