Diagnostic Bacteriology Protocols presents a broad range of currently used techniques for detecting, identifying, and differentiating bacterial cell components, including structured proteins, nucleic acids, enzyme activities, lipopolysaccharides, and metabolites. It describes each technique in simple easy-to-follow steps that guarantee reproducible results for novices and senior researchers alike. Troubleshooting tips, alternative ways of performing procedures, and informative explanations about why certain steps are necessary—aids not usually found in standard journal recipes help even highly skilled researchers to obtain the results they want.
