Gene-Edited Pigs Resistant To Billion Dollar Virus – Eurasia Review
Scientists have produced pigs that can resist one of the world’s most costly animal diseases, by changing their genetic code. Tests with the virus – called Porcine Reproductive and Respiratory Syndrome, or PRRS – found the pigs do not become infected at all. The animals show no signs that the change in their DNA has had any other impact on their health or wellbeing. The disease causes breathing problems and deaths in young animals and if pregnant sows become infected, it can cause them to lose their litter. The virus infects pigs using a receptor on their cells’ surface called CD163.
Researchers at the University of Edinburgh’s Roslin Institute used gene editing techniques to remove a small section of the CD163 gene. The team collaborated with Genus PLC, a leading global animal genetics company, to produce pigs with the specific DNA change. Previous studies had shown that cells from these animals were resistant to the virus in lab tests. This is the first time researchers have exposed these pigs to the virus to see if they become infected. Other groups have used gene editing to create PRRS-resistant pigs by removing the whole CD163 receptor.
Genetically modified animals are banned from the food chain in Europe. GM techniques have been controversial because they can involve introducing genes of other species into an animal.
20 Mistakes: How to Kill Your Pet |
Putting your pet on the direct sunlight on the hot summer day because he is always in the lonely dark places and needs to get some tan. NO. A LESSON TO LEARN: Guinea pigs have LOW tolerance for high temperatures and could suffer a heat stroke. Giving your pet human junk food or anything that is not on the guinea pig feeding page list. A LESSON TO LEARN: Learn everything from the guinea pig feeding page.
A LESSON TO LEARN: Again, pet stores want your money, not your guinea pig’s health. Provide vitamin C through natural food, not through neat colorful artificial supplements from pet stores. If not sure why, go with this: If your pet does not like the taste of the supplemented water, it will stop drinking the supplemented water. A LESSON TO LEARN: Guinea pig is not a student, and as such, does not have such a strong immune system. A LESSON TO LEARN: If you yell at your pet it won’t trust you, you become more frustrated and yell more and finally get detached and hating all the guinea pigs in the world, thus moving to Peru.
A LESSON TO LEARN: Guinea pigs have small feet which easily could slip through the mesh, thus irritating the feet, causing foot sores and bumblefoot. A LESSON TO LEARN: Learn how to properly hold your pet. Don’t let ANY of your other pets near your guinea pig.

Cat fleas are more common on cats, dogs and humans than dog fleas and human fleas. FLEAS AND DISEASE. Fleas often probe the skin before taking a blood meal. A bacterium spread by fleas killed 25 million people, more than a quarter of the European population, in 14 th century Europe. The disease is typically carried by wild rodents, and transmitted to the fleas that bite them.
Humans typically contract the disease from the bites of infected fleas, or through skin abrasions that contact the blood of infected animals or the feces of infected fleas. Another disease transmitted by fleas is murine typhus. Perhaps a month after the eggs are laid, adult fleas emerge from their pupal cocoons. Adult fleas are found on their hosts pets should be treated with prescription or over-the-counter treatments. These include products containing fipronil or imidacloprid, active ingredients that kill fleas but have relatively low toxicity.
Steam cleaning of furniture and floor coverings will help eliminate remaining fleas. Physical pressure on the carpet from vacuuming can trigger the emergence of fleas from their pupal cocoons, exposing them to pesticide applications. Fleas are unlikely to be in the center of a spacious room or sunny yard.
