Over the last decade, interest in mycoplasmas has been greatly sti- lated by the spread of contagious bovine pleuropneumonia (CBPP), caused by Mycoplasma mycoides subsp. mycoides SC, in Europe and Africa and the discovery of a possible association between mycoplasmas and AIDS. During this period there has also been a recognition by control authorities and int- national organizations, including the Office International des Epizooties, that mycoplasmas are major causes of economic loss in livestock and continue to be a problem in humans as a result of a range of chronic respiratory and urogenital diseases. However, it is likely that the true significance of my- plasmas is still underestimated because of the difficulties in working with these extremely fastidious microorganisms. Advances in such laboratory technology as DNA amplification has enabled the detection of unrecoverable mycoplasmas in tissue samples and this will provide us with a better understanding of their role in disease. Important developments have also been seen in more conv- tional areas such as serological tests and media formulation enabling improved recovery and identification. Mycoplasma Protocols provides in a single volume up-to-date and easy-- follow methods for the detection, isolation, identification, and characterization of mycoplasmas, with a major emphasis on those of medical and veterinary significance. It also includes biochemical, genetic, and molecular techniques that will form the basis of understanding pathogenicity and, particularly, - hesion to host cells.
