The Indian scientists in Pune have successfully captured the very first images of the deadly coronavirus that causes the novel Covid-19 disease. They have used the transmission electron microscope imaging to capture the images.
The scientists caught the images of the Sars-Cov-2 virus that causes the Covid-19 virus from the throat swab of the virus case which marks the first case that was confirmed in the laboratory.
"One particular virus particle was very well preserved, showing features very typical of coronaviruses. This particle was 75 nm in size and showed patchy stain pooling on the surface and a distinct envelope projection ending in round peplomeric (glycoprotein spike on the viral surface). These bind only to certain receptors on the host cell," said Dr. Atanu Basu, deputy director and head of electron microscopy and pathology at NIV Pune said.
"Seven negative-stained virus particles that looked like coronavirus-like particles were imaged in the fields scanned. These included the round shape of the virus with an average size of 70-80 nm and a cobbled surface structure having envelope projections that averaged 15Â±2 nm in size," Dr. Basu added.
Quite surprisingly, the gene samples from Kerala that were collected at NIV Pune has found out that the virus matches 99.98% with the virus originated from the Wuhan province of China.
