Effects of ionophores and dicyclohexylcarbodiimide on Mycoplasma gallisepticum adherence to erythrocytes.
To test the influence of the electrochemical ion gradient across mycoplasma membranes on the capacity of organisms to adhere to host cells, Mycoplasma gallisepticum cells were treated with valinomycin, carbonylcyanide m-chlorophenylhydrazone, and N,N'-dicyclohexylcarbodiimide (DCCD) singly or in combination. Uptake of [3H]tetraphenylphosphonium by the treated cells was employed as a measure of ...
متن کاملAttachment of killed Mycoplasma gallisepticum cells and membranes to erythrocytes.
To correlate viability with attachment capacity, Mycoplasma gallisepticum cell harvested at different growth phases and treated by various agents were tested for their capacity to attach to human erythrocytes. The results show that viability per se is not essential for M. gallisepticum attachment to erythrocytes, as cells killed by ultraviolet irradiation anmd membranes isolated by lysing M. ga...
متن کاملAdherence of Mycoplasma gallisepticum involves variable surface membrane proteins.
Adherence of Mycoplasma gallisepticum to erythrocytes was examined by colony immunoblotting, detergent phase fractionation, trypsin treatment, comparison of protein profiles, and comparison of erythrocyte-bound mycoplasma protein fractions of hemadsorption-positive and -negative mutants. The binding of M. gallisepticum to chicken or human erythrocytes was found to be mediated via surface-expose...
متن کاملAvian mycoplasmosis (Mycoplasma gallisepticum).
Mycoplasma gallisepticum is the most economically significant mycoplasma pathogen of poultry, and has a world-wide distribution. In common with other mycoplasmas, M. gallisepticum is minute in size with minimal genetic information and with a total lack of a bacterial cell wall. These properties are reflected in a high degree of interdependence between M. gallisepticum and the host animal, and i...
متن کاملAdherence of Ureaplasma urealyticum to human erythrocytes.
Ureaplasma urealyticum (four serotypes and two clinical isolates) were metabolically labeled with radioactive methionine to a high specific activity. Labeling allowed the study of the mechanism of adherence to human erythrocytes. The adherence mechanism was complex and partially mediated by proteinaceous surface components. The binding sites on the erythrocytes were partially sensitive to neura...
