Leptospirosis strains identified in Uruguay cattle
Leptospirosis infections, caused by Leptospira bacteria, occur in people and animals around the world, but different strains of the bacteria may vary in their ability to cause disease and to jump between species. Now, researchers have for the first time described the characteristics of the Leptospira variants that infect cattle in Uruguay.
Zarantonelli et al. 2018. Isolation of pathogenic Leptospira strains from naturally infected cattle in Uruguay reveals high serovar diversity, and uncovers a relevant risk for human leptospirosis. PLOS Neglected Tropical Diseases 12 (9): e0006694 DOI: 10.1371/journal.pntd.0006694

Rabies Outbreak in Western Alaska
Arctic fox rabies is enzootic in populations of arctic and red fox populations along Alaska’s northern and western coasts. This means rabies is always present in these populations at some low level but periodically there can be outbreaks called epizootics (an outbreak in animal disease rather than an epidemic as is it is called when occurring in a human population). However, the winter of 2020-2021 ushered in a widespread outbreak with persistent and large focus in and around Nome.

Scientists of "Beringia" came close to explaining the mystery of "smelly" whales in Chukotka
The specific "medical" smell of whale meat may be caused by liver disease or the animals' diet. Chukchi Sea hunters began noticing the pungent, unpleasant smell in some whales about 20 years ago. Recently, the number of stinky whales has increased. Scientists with Beringia National Park analyzed the isotopic composition in 46 samples of gray whales. “Stinky” whales had significantly lower levels of heavy nitrogen. Scientists still must understand whether this is a result of liver disease or a diet based on algae. Scientists hope to study more high-quality samples of “stinky” whales.

Threatened listing proposed for sunflower sea star after population devastated by wasting disease
It causes legs to fall off and, ultimately, results in disintegration of the animals’ bodies. Climate change may be behind that disease, as the arrival of Pacific marine heat waves coincided with the disease outbreak, according to federal biologists.The sea star, with a range from Baja California to the Aleutians, would be the first sea star with an Endangered Species Act listing.
