Herpes is one of the most widespread human viral pathologies. The article depicts a special modification of polymerized chain reaction--(PCR)--(referred to as "nested"), which has a higher sensitivity, specificity and reliability as compared to the ordinary PCR, and which is designed to detect the herpes viruses. The method was initially tested at purified preparation of viral DNA, and later--at clinical materials obtained from patients and healthy donors. Secretions from the urogenital tract (smears), scrapes from the urogenital tracts and urinal cellular samples were examined in patients. Herpes simplex was detected in all cases. As for the healthy people, the identical examinations produced in them mainly the negative findings. Therefore, the nested PCR is a simple, sensitive and effective instrument in the diagnostics and prevention of herpes; it can be recommended for a comprehensive usage in medical practice. |
