GDO'lu sivrisinekler...

#İngiltere'nin #Oxford kenti yakınlarındaki bir laboratuvarda, biyoteknoloji firması #Oxitec sıtma gibi ölümcül hastalıklarla mücadele amacıyla genetiği değiştirilmiş (#GDO) sivrisinekler üretiyor #Canlı #Sağlık #Çevre #Hayvan

So, note this... "analysis suggests the entirely new virus was created by an ECHV virus exchanging fragments of DNA with another virus, known as a ‘recombinant event’." I have been concerned that mucking around with #GM mosquitoes could cause new illness by combining DNA. There has been speculation about that being the case with #Zika.

Never-before-seen virus that causes malaria-like illness 'already circulating'

Story by Katherine Fidler, December 4, 2023

"A never-before-seen virus that causes a malaria-like illness has been detected in Peru.

"The disease was first seen in a man in his twenties, who went to hospital after suffering from two days of fever, chills, headaches and muscle pain among other symptoms.

"Doctors were unable to identify what was causing the mystery illness, but further laboratory investigation revealed a previously unknown pathogen."

More concerns about #GE mosquitoes -- especially since they can breed when exposed to #tetracycline

Behind an academic paywall:

Science snipes at #Oxitec transgenic-mosquito trial

by Nidhi Subbaraman

Nature Biotechnology volume 29, pages 9–10 (2011)

"#Oxitec's plans for transgenic #mosquito trials have not been without controversy in the past. They have been criticized by environmental groups, such as Ottawa-based #ETCGroup and #EcoNexus of Oxford, concerned about the risks of releasing an entirely new strain of organism into the environment".

So, yeah, some concerns about #Oxitec #GE #GM #mosquitoes were brushed off as "conspiracy theories" (of course the whole Zika connection was one), but it turns out that some of the concerns were real. To summarize, GE mosquitoes, allegedly bred to be sterile, become not-so-sterile when exposed to #Tetracycline -- a common antibiotic used in cattle, companion animals, and humans!

Following Review of Available Data and Public Comments, EPA Expands and Extends Testing of Genetically Engineered Mosquitoes to Reduce Mosquito Populations
For Release: March 7, 2022

"To ensure that no OX5034 female mosquito offspring survive, EPA has taken the precaution of restricting release of OX5034 mosquitos within 500 meters of potential sources of tetracyclines, as there is a remote chance that environmental sources of tetracycline could have enough tetracycline present to act as a counter agent to the OX5034 female mosquito-lethal trait. Releases must not occur within 500 meters from the outer perimeter of 1) wastewater treatment facilities; 2) commercial citrus, apple, pear, nectarine, and peach crops; and 3) commercial cattle, poultry, and pig livestock facilities. The 500-meter distance creates a conservative buffer zone between OX5034 release points and potential environmental tetracycline sources."
"Oxitec must monitor for OX5034 female mosquitoes within 100 meters of those potential environmental tetracycline sources."
