New Research Helping to Reveal More About Megaviruses


Swansea University has played a key role in research to develop a greater understanding of megaviruses and their potential to cause life-threatening illnesses.

The findings, which have just been published in the prestigious Proceedings of the National Academy of Sciences of the United States of America (PNAS), examine the unexpected genes carried by these giant viruses found inside amoebae.

Professor David Lamb, recipient of a Fulbright Scholarship, worked with his Swansea University Medical School colleagues Professor Steven Kelly, Dr. Claire Price and Dr. Andrew Warrilow on the paper On the occurrence of cytochrome P450 in viruses.

Lamb explained that amoebae can be described as Trojan horses as they carry the megaviruses which can be as big as bacteria. "Some of these megaviruses have several thousand genes. We are cataloguing them and examining their properties. We know these viruses may be linked to some forms of pneumonia so gaining a better understanding of them will help us to develop ways of tackling those viruses."

The paper follows on from the time Lamb spent in the U.S. as one of Swansea University's first-ever Fulbright Scholars.

His place on the program saw him hosted by the Oceans and Human Health Department of the Woods Hole Oceanographic Institute in Massachusetts, where he spent a year developing his research into cytochrome P450 biodiversity.

The paper also saw the Swansea academics collaborate with Dr. Jed Goldstone and professor John Stegeman, from Woods Hole, Alec Follmer, Marie True and professor Tom Poulos, from the University of California Irvine and professor David Nelson at the University of Tennessee.

Lamb added, "This is very interesting research and our findings herald a new era of understanding regarding the evolution of this important gene family, with implications for understanding the biology and the origin of the giant viruses themselves. "
