University of Missouri researchers found that bisphenol A alters male painted turtle brains to promote behaviors generally exhibited by females, including better memory and spatial navigation. The work builds on a prior study that showed the BPA in waterways could influence development of sex organs, and the new findings raise concerns about adult social behavior in turtles whose brains have been influenced by the chemical, which is a common component of consumer products.

We are finding problems with the vendor (a glider mill) that is selling a fairs, malls, and on-line. Gliders are not in good condition, diet is questionable, and likely the breeders are being pushed so joeys are weakened. I am bringing this to the attention of exotic mammal vets at next week’s ExoticsCon in Portland Oregon.
Veterinarian Greg Hurst reminds people that animals should not be an impulse buy, noting that sugar gliders sold at the Illinois State Fair are a good example of an impulse pet purchase that doesn’t end well, because some owners are now having problems. “Every one of these owners really didn’t plan on having a sugar glider prior to the state fair,” Dr. Hurst said.

After a turtle named Uga was likely attacked by rats, her back leg was heavily damaged and had to be amputated, leaving her immobile. Veterinarian Nicola Di Girolamo of Italy worked with a 3D-printing company to develop a prosthetic device, and now Uga can motor around.

Tens of thousands of fish have died in the Yellowstone River, prompting Montana officials to close 183 miles of the waterway to rafting, fishing and other human activity in an effort to halt the spread of a parasite thought to have caused the losses. The parasite, which is not native to the area and was likely brought in by people or birds, causes deadly kidney disease in the fish.

Veterinarian Mark Rochat of Purdue University’s College of Veterinary Medicine fixed the dislocated hip of a wallaby from the Columbian Park Zoo. Dr. Rochat used a Tightrope device to create a new round ligament and re-align the hip joint in a surgery that was successful but challenging because wallaby anatomy differs from that of dogs.

I wonder if this is one of the reasons we are more likely to get viral infections in the winter…
Studies in mice showed that viral loads associated with influenza and herpes were 10 times higher among animals infected in the morning than those infected in the evening, and disrupting the body’s circadian rhythm increases vulnerability to infection, something that has implications for people with erratic work schedules. The effect might be due to BMAL1 gene activity, which peaks in the afternoon in mice and in people, and drops off in the winter.
Studies have implicated brain inflammation in Alzheimer’s disease severity, and mefenamic acid, a nonsteroidal anti-inflammatory drug, appeared to reverse memory problems akin to Alzheimer’s in mice. The drug targets the NLRP3 inflammasome, an inflammatory pathway linked to damaged brain cells.
