The Direct Detection of Microorganisms in Clinical Samples

The Direct Detection of Microorganisms in Clinical Samples focuses on the most practical and widely used procedures for direct detection of microorganism in clinical specimens. It considers application to virology, mycology, and bacteriology. Organized into three parts, the book begins with established techniques for visualization of intact organism in clinical samples. The book then deals with immunologic techniques for detecting soluble microbial antigens. The last part considers diverse non-immunologic methods for detecting soluble constituents of organisms and their metabolites. Clinical microbiologists, infectious disease clinicians and researchers, and individuals working in analogous areas will find this book invaluable.
