Exploring seven decades of groundbreaking microbiological research and viral surveillance at Ukraine's premier scientific institution
In a world still grappling with the aftermath of a global pandemic, the work of virologists and microbiologists has never been more critical.
For seven decades, the D.K. Zabolotny Institute of Microbiology and Virology of the National Academy of Sciences of Ukraine has stood as a scientific bastion against the invisible threats that shape human health, agriculture, and ecosystems. From an era when microbes were barely understood to today's age of genomic surveillance, this institute has continuously evolved its methods and mission.
As we celebrate its 70th anniversary, we explore not only its storied history but its groundbreaking work that helped trace the path of COVID-19 across Ukraine—a testament to how scientific resilience can persist even amidst unprecedented challenges.
The establishment of the D.K. Zabolotny Institute emerged from a pressing need to systematize the study of microorganisms that profoundly impacted Ukrainian society. The institute's namesake, Danylo Kyrylovych Zabolotny, was among Ukraine's most influential scientists, whose pioneering work in epidemiology laid the groundwork for future generations of researchers.
Ukraine has produced at least two Nobel laureates in microbiology and related fields, including I.I. Mechnikov 3 .
Natives of Ukraine have made "a great contribution to the development of microbiology and epidemiology" 3 .
The institute has continually adapted to new scientific challenges while honoring foundational principles.
| Scientist | Field of Contribution | Key Achievements |
|---|---|---|
| D.K. Zabolotny | Epidemiology | Pioneering research on infectious diseases, especially cholera and plague |
| I.I. Mechnikov | Immunology | Nobel Prize (1908) for phagocytosis theory, foundational immunology research |
| M.L. Gamaleya | Bacteriology | Development of bacterial research methods and vaccine studies |
| S.M. Vinogradsky | Environmental Microbiology | Discovered chemosynthesis, pioneered cycle of life research |
| L.V. Gromashevsky | Virology | Significant contributions to theoretical epidemiology and virus classification |
When COVID-19 emerged as a global threat, the D.K. Zabolotny Institute's expertise became more critical than ever. In a remarkable demonstration of scientific adaptability, researchers embarked on an ambitious project to sequence SARS-CoV-2 genomes, tracing the evolution and spread of the virus across Ukraine throughout the various waves of the pandemic 7 .
The institute's approach combined fieldwork precision with cutting-edge genomics:
Researchers obtained nasopharyngeal swabs from hospitalized and non-hospitalized patients across multiple Ukrainian cities including Kyiv, Dnipro, Lviv, and Kharkiv between May 2020 and May 2022 7 .
Using standardized commercial kits, scientists extracted viral RNA from patient samples, then confirmed COVID-19 infections through RT-PCR tests 7 .
The team employed multiple sequencing approaches, utilizing Illumina's Respiratory Virus Oligo Panel initially, later transitioning to the ARTIC protocol 7 .
Using sophisticated bioinformatics pipelines, researchers analyzed genetic sequences. All sequences were uploaded to the GISAID EpiCoV™ global database 7 .
| Pandemic Wave | Time Period | Dominant Variant(s) | Key Characteristics |
|---|---|---|---|
| First | May-Nov 2020 | Early lineages | Original virus strain with minimal mutations |
| Second | Feb-Jun 2021 | Alpha (B.1.1.7) | Increased transmissibility |
| Third | Sep-Dec 2021 | Delta (B.1.617.2) | Enhanced severity and vaccine evasion |
| Fourth | Jan-Jun 2022 | Omicron (BA.1, BA.2) | Significant immune escape but reduced severity |
The genomic data revealed crucial insights into Ukraine's pandemic experience. Each wave was characterized by the distinct dominance of specific variants, with the Omicron variant particularly well-represented in the sequencing data—partly due to the institute's expanding laboratory capacity as the pandemic progressed 7 .
Perhaps the most remarkable aspect of this research was how it continued even during extreme duress. The fourth wave of COVID-19 in Ukraine coincided with the 2022 military invasion, creating unprecedented challenges for scientific work 7 .
Despite this, the institute's researchers persevered, even collaborating with international partners to investigate potential virus spread through refugee movements by comparing viral mutations found in Ukraine and neighboring Poland 7 .
Initial sequencing using Illumina Respiratory Virus Oligo Panel - Established baseline understanding of early SARS-CoV-2 strains in Ukraine
Transition to ARTIC protocol for sequencing - Improved efficiency and joined international standardized approach
Expanded sequencing during Omicron wave - Documented variant shift and contributed data to global repositories
Analysis of refugee situation impact on variant spread - Unique research on how conflict influences disease dynamics
Data sharing via GISAID database - Contributed to international pandemic response efforts
What does it take to study the invisible world of microbes? Modern microbiology relies on an array of specialized chemical tools known as reagents that enable scientists to detect, identify, and analyze microorganisms with astonishing precision. These substances are the unsung heroes of laboratory science, facilitating reactions that reveal critical information about pathogens 4 .
At their core, reagents are substances added to test systems to cause a chemical reaction, test for a specific chemical, or confirm that a reaction has occurred. Unlike reactants, which are consumed in the process, reagents typically facilitate the reaction without being fully used up 4 .
Their purity is paramount—"reagent-grade" designation indicates they meet strict standards for purity, ensuring they won't contaminate experiments or produce misleading results 4 .
| Reagent Type | Primary Function | Application Examples |
|---|---|---|
| Viral Transport Medium (VTM) | Preserves specimen integrity during transport | Maintaining RNA stability in nasopharyngeal swabs for SARS-CoV-2 testing 7 |
| PCR Master Mixes | Amplifies target genetic sequences | Detecting viral RNA in patient samples through reverse-transcriptase PCR 7 |
| Sequencing Reagents | Enables genome sequencing | Illumina sequencing kits for determining SARS-CoV-2 variants 7 |
| Enzyme Solutions | Facilitates specific biochemical reactions | Restriction enzymes for genetic engineering; polymerases for DNA amplification |
| Cell Culture Media | Supports growth of microorganisms | Culturing viruses for research in controlled laboratory settings 5 |
The D.K. Zabolotny Institute's COVID-19 surveillance work exemplifies how these tools come together in practice. The researchers used specialized reagents at every stage—from the viral transport medium that preserved patient samples to the enzyme mixtures that enabled RNA extraction, PCR amplification, and ultimately genome sequencing 7 .
Beyond the pandemic response, microbiological reagents have countless applications across healthcare, environmental science, and biotechnology. They enable everything from diagnosing infections and monitoring antibiotic resistance to developing new biofuels and understanding ecosystem dynamics.
As the D.K. Zabolotny Institute of Microbiology and Virology marks its 70th anniversary, its legacy offers powerful insights about scientific perseverance. From its foundations in traditional epidemiology to its current work in genomic surveillance, the institute has repeatedly demonstrated that understanding microbes requires both historical knowledge and innovative thinking.
