Question

Как учёным удалось обнаружить вирусы и изучить скажите пожалуйста

Answer 1

Я думаю, вирус попадал в живой организм (например в организм человека), человека проверяли и находили вирус.

Answer 2

Первый вирус который был обнаружен - это вирус табачной мозаики. До этого были известны бактерии, но о вирусах никто ничего знать не знал.. и вот в 1892 году Дмитрий Ивановский фильтровал препарат больных растений на наличие бактерий. Но как бы ни фильтровал - все-равно раствор оставался заразным.. и тогда возникло предположение, что это не бактерии, а что-то другое, что-то еще более маленькое

How Scientists Discovered Viruses and Studied Them

Scientists have made significant progress in discovering and studying viruses over the years. Through a combination of observation, experimentation, and technological advancements, they have been able to uncover the existence of viruses and gain a deeper understanding of their characteristics and behavior.

Observation and Early Discoveries: - The first step in the discovery of viruses was through observation. Scientists noticed that certain diseases, such as tobacco mosaic disease in plants and foot-and-mouth disease in animals, could be transmitted from one organism to another through a filter that blocked bacteria. - In the late 19th century, Dmitri Ivanovsky and Martinus Beijerinck independently conducted experiments that demonstrated the presence of an infectious agent smaller than bacteria. They called these agents "filterable viruses" because they could pass through filters that retained bacteria.

Development of Microscopy Techniques: - The development of microscopy techniques played a crucial role in the study of viruses. With the invention of the electron microscope in the 1930s, scientists were able to visualize viruses directly for the first time. This breakthrough allowed them to study the structure and morphology of viruses in detail.

Culturing and Isolation: - Another important step in virus discovery was the ability to culture and isolate viruses. Scientists developed techniques to grow viruses in the laboratory, which allowed for further study and experimentation. - In 1892, Dimitri Ivanovsky successfully transmitted the tobacco mosaic virus to healthy plants by using sap from infected plants. This experiment demonstrated that viruses could be isolated and propagated outside of their host organisms.

Advancements in Molecular Biology: - The field of molecular biology has greatly contributed to our understanding of viruses. With the discovery of DNA and RNA as the genetic material, scientists were able to study the genetic makeup of viruses and understand how they replicate and evolve. - The development of techniques such as polymerase chain reaction (PCR) and DNA sequencing has allowed scientists to identify and characterize different types of viruses more accurately.

Technological Advancements: - Technological advancements have played a significant role in virus discovery and research. For example, the invention of next-generation sequencing (NGS) has revolutionized the field by enabling rapid and high-throughput sequencing of viral genomes. - NGS has allowed scientists to identify new viruses, study viral diversity, and track the evolution of viruses over time.

Collaboration and Global Surveillance: - Collaboration among scientists and global surveillance efforts have been crucial in detecting and studying viruses. Organizations like the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) work together to monitor and investigate outbreaks, identify new viruses, and develop strategies for prevention and control.

In conclusion, scientists have made significant progress in discovering and studying viruses through a combination of observation, experimentation, and technological advancements. The development of microscopy techniques, culturing and isolation methods, advancements in molecular biology, and collaboration among scientists have all contributed to our understanding of viruses and their impact on human and animal health.
