While many of us hold the opossum in about as much regard as a sewerage rat , rick out , we ought to be show this special urban trashivore a lil ’ more respect . Opossums may end up saving yard of mankind from venomous snakebite each year .
That ’s because scientists have just oversee to synthetically invent a possum protein that ’s able to neutralize bites from the U.S. Western Diamondback rattlesnake and Russell ’s Viper from Pakistan . The researchers behind the discovery , who are presenting their employment today at the annual coming together of theAmerican Chemical Society , are hopeful that the antivenom will prove effectual against a all-inclusive compass of deathly serpent .
Worldwide , an estimate 421,000 multitude are prick by a poisonous ophidian each twelvemonth . Roughly 20,000 of those bite are lethal , with the absolute majority of deaths take place in rural parts of India , Southeast Asia , Africa and South America , where access to handling is circumscribed . But possums , which eat snake for dejeuner , shrug off the effects of these deadly malice with relaxation . In the other 1990 ’s , a group of researchers identify the specific blood serum protein in opossum that was able to neutralize bites . But until now , no one had followed up on that find and attempt to educate an antivenom therapy for humans .

By inserting the gene that encodes the opossum ’s antivenom protein into the bacterium E. coli , a inquiry team led by Claire Kornives at San Jose State University was capable to re - synthesise the protein in the lab . In apress spill , Kornives explain that her approach differs from how antivenoms are normally produced :
“ Our approach is different because most antivenoms are made by injecting the venom into a horse and then processing the serum , ” says Komives . “ The blood serum has additional components , however , so the patient often has some kind of adverse chemical reaction , such as a rash , itchiness , wheezing , speedy spirit rate , fever or consistency aches . The peptide we are using does not have those negatively charged result on mice . ”
The next step for the researchers will be see how their antivenom take hold up against a scope of toxins . They ’re optimistic that the blood serum will prove effective against many venomous serpent , and if we ’re lucky , it may even work against scorpions , as well as some plant and bacterial toxin .
presently , it seems , we may all be capable to carry a life - saving gibe of possum serum with us wherever we go . [ American Chemical Society ]
