Molecular Diagnosis and Treatment of Infectious Diseases

Medical diagnosis is the process of determining the type of disease or condition that explains a person's symptoms and signs. Laboratory tests may identify the organisms directly by visualizing the organism on a culture by a microscope or indirectly identifying antibodies to the organism. General types of tests include microscopy, culture and immunologic tests i:e; agglutination tests such as western blot, latex agglutination, enzyme immunoassays, complement fixation tests, precipitation tests and nucleic acid/ no- nucleic acid-based identification methods. Treatment of infections involves patient care and moral support including corresponding therapies. Bacterial infections can be easily treated by administering antibiotics to the patients. Yeast infections can be primarily treated by sterilization and the parasitic infections can be treated by antiparasitic drugs. Diseases such as cancer can be treated by chemotherapy techniques. Advanced techniques have proved that there is no disease that cannot be treated.
