To the hospital a woman at the age of 23 was admitted who during pregnancy has not passed routine microbiological and virological survey. Her baby has immediately after birth the skin and mucous small bubbles on the face of limited swollen spots. Later developed the damage of central nervous system and the baby was not saved. When sowing the contents of the bubbles in the blood agar growth of the pathogen have been identified, and during infection of tissue culture they observed CPE (simplasty, intranuclear inclusions, degeneration of cells). Which organism is the most likely causative agent of neonatal infections?
Staphylococcus
Gonococcus
Chlamydia
Herpes simplex virus
Cytomegalovirus

Herpes simplex virus
Varicella zoster virus
Cytomegalovirus

Epstein-Barr virus
The student of medical school, hospitalized in the infectious disease clinic, on the 2nd day of the disease is suspected infectious of mononucleosis. What is the result of laboratory tests can confirm the diagnosis of a student on the day of admission?
Detection of Ig M-antibodies to herpes simplex virus
Detection of Ig M-antibodies to the Epstein-Barr virus
Identification of 4-fold rise of antibodies to Epstein-Barr virus
Isolation (separation) of the herpes virus
