title: Ultrastructure and biological properties of Avian influenza viruses following cryopreservation
abstract: Ultrastructure and infectious activity of avian influenza virus (strain А/Chicken/Sivash/02/05 (H5N1)) following cryopreservation and low temperature storage at –20, –70, and –196°C during various terms from 25 days up to 143 months using electron microscopy, serological and virological methods were investigated. Avian influenza viruses strain А/Chicken/Sivash/02/05 (H5N1) is stored in the Collection of Pathogens of the National Scientific Center ‘Institute of Experimental and Clinical Veterinar
