Where Will the World’s Next Zika, West Nile or Dengue Virus Come From?

After collecting data and comparing it with every known mammal and bird species on Earth, scientists from the University of California, Davis, have identified wildlife species that are the most likely to host flaviviruses such as Zika, West Nile, dengue and yellow fever. Flaviviruses are known to cause major epidemics and widespread illness and death throughout the world.

Deadly Marburg Virus Found in Sierra Leone Bats

Scientists have discovered Marburg virus in fruit bats in Sierra Leone. This is the first time the deadly virus has been found in West Africa. Five Egyptian rousette fruit bats tested positive for active Marburg virus infection. Scientists caught the bats separately in three health districts: Moyamba, Koinadugu and Kono.

Coconut the Snow Leopard Recovers From Eyelid Surgery

Coconut, the snow leopard cub born at the Sacramento Zoo earlier this year, underwent a rare eyelid surgery on Wednesday, October 24. UC Davis veterinary specialists and the Sacramento Zoo veterinary team collaborated to correct a congenital eyelid defect known as coloboma. This ocular deformity is sometimes documented in snow leopards under human care. Coconut was also born with other birth defects that impact his mobility.

Bats are the Major Reservoir of Coronaviruses Worldwide

Results of a five-year study in 20 countries on three continents have found that bats harbor a large diversity of coronaviruses (CoV), the family of viruses that cause Severe Acute Respiratory Syndrome Coronavirus (SARS) and Middle East Respiratory Syndrome Coronavirus (MERS).

Paving the Way for Pathogens

Coastal waters near heavy human development are more likely to receive land-based “pathogen pollution,” which can include viruses, bacteria and parasites, according to a recent study from the University of California, Davis. The study said higher levels of rainfall and development increase the risk of disease-causing organisms flowing to the ocean.

Chewed Plants Help Detect Viruses in Wild Mountain Gorillas and Monkeys

Chewed bark, leaves and fruit discarded by mountain gorillas provide a simple way to test the endangered apes for viruses without disturbing them, according to scientists from the University of California, Davis, studying mountain gorillas and golden monkeys in East-Central Africa.

The method is described in a study published recently in the American Journal of Primatology. The study is led by UC Davis’ One Health Institute and Gorilla Doctors, a program led by the nonprofit Mountain Gorilla Veterinary Project and UC Davis.
