EPA move to phase out animal testing threatens public health
EPA Administrator Andrew Wheeler's initiative to phase out the use of mammals in all chemical safety tests by 2035 is a noble but unrealistic goal that threatens to undermine medical research and public health, writes FBR President Matthew R. Bailey. "In some cases, there is no other way to evaluate the safety and efficacy of substances than to study their impact in animals," Bailey writes.

Experimental vaccine protects monkeys from 4 hemorrhagic fever viruses
An investigational vaccine protected monkeys from four types of hemorrhagic fever virus endemic to certain areas of Africa, including strains of Ebola virus and Marburg virus, the NIH announced. No other licensed vaccine protects against any of the viruses, all of which can be fatal.

Veterinary researchers map blood-brain barrier response to metastases
Veterinarian Tiffany Lyle, an assistant professor of veterinary anatomic pathology at Purdue University, and her research team have mapped how the blood-brain barrier becomes a blood-tumor barrier in lung cancer that has metastasized to the brain, preventing drugs from penetrating the tumors. Their research, published in Oncotarget, showed that astrocytes undergo changes during the transition, and Dr. Lyle says the finding will be key in developing effective treatments.

An axolotl at Chapultepec Zoo regenerated a fully functional eye within two months of losing nearly half its face to a fungal infection, highlighting the reason scientists interested in tissue regeneration study axolotls, whose wild populations are threatened by invasive species and water pollution. Axolotls also appear to be resistant to cancer, possibly thanks to their regenerative ability, says veterinarian and axolotl researcher Erika Servin Zamora.

Study: Signs of Rocky Mountain fever develop soon after tick bite
A study in the Journal of Medical Entomology found that guinea pigs did not show signs of illness when exposed for 30 minutes or less to American dog ticks infected with Rickettsia rickettsii, but guinea pigs exposed for 8 hours and 12 or more hours developed mild fevers and high fevers, respectively. The findings suggest that the host can develop Rocky Mountain spotted fever within a short period of time after an infected tick begins feeding.

Gene therapy for dogs with mitral valve disease could be used in people
Young Cavalier King Charles spaniels are prone to mitral valve disease, which affects about 6% of all dogs, and a gene therapy being tested in the breed might offer a cure for dogs as well as people with the condition, says veterinary cardiologist Vicky Yang of Tufts University's Cummings School of Veterinary Medicine. The treatment prevents thickening of the heart valve.

Swine virus could cause worldwide shortage of critical anticoagulant
African swine fever virus has killed millions of pigs in China, causing alarm among health care providers and drugmakers about the possibility of a prolonged shortage of heparin, an anticoagulant derived from pig intestines.
