Shahinyan, Doctor habil. in Medicine, Chief Researcher, Head of the Laboratory of Molecular Epidemiology of Nosocomial Infections of the Gamaleya National Center of Epedimiology and Microbiology (1995-2020). Shaginyan I.A. worked his way up from a senior laboratory assistant in the Department of Microbiology to the head of a laboratory, in charge of one of the modern scientific directions - the study of genomic polymorphism of pathogens of infectious diseases. His work, together with his students and clinicians, was devoted to the molecular mechanisms of the formation and functioning of communities of pathogens of nosocomial infections and the molecular mechanisms of microevolution of pathogens, that cause healthcare associated infections. Joint cooperation with the Moscow Center for Cystic Fibrosis began in 2005, under the leadership of I.A. Shaginyan. The microbiological diagnostics of chronic lung infection in cystic fibrosis patients in Russia have been improved. Molecular genetic methods were included in the diagnostic algorithm, which allowed to carry out accurate identification, correct antibiotic therapy and preventive measures. The molecular genetic studies have shown the variability of the population of microorganisms in the lungs during chronic lung infection, which confirmed the need for constant microbiological monitoring of the lung microflora in patients with cystic fibrosis. I.A. Shahinyan passed away on May 27, 2020. His work is continued by his followers.history of medicineIgor A.
