Diagnosis of Pathogenetic microorganisms

Diagnosis of Pathogenetic microorganisms is direct Examination and Techniques. Immunofluorescence, immuno-peroxidase staining, and other immunoassays may detect specific microbial antigens. Genetic probes identify genus- or species-specific DNA or RNA sequences.

Culture: Nonselective (noninhibitory) media and Selective media contain inhibitory substances.

Serodiagnosis: The rising titer of specific IgG antibodies or presence of specific IgM antibodies.
