The Icelandic Food and Veterinary Authority (MAST) has found evidence of infectious salmon anaemia (ISA) in an open-net salmon farm in Reyðarfjörður fjord, East Iceland. ISA is a highly infectious viral disease that has no treatment and causes high mortality in farmed Atlantic salmon.
When Kathleen Reed descended for her usual weekly dive off the coast of Nanaimo, B.C., last Saturday she was shocked by how many dead sea cucumbers she saw. Experts and harvesters fear that sea cucumbers are being hit by an illness similar to sea star wasting disease.
Several people have fallen ill with food poisoning after eating shellfish in B.C. in the last 10 days, and health officials are warning that warm ocean waters might be to blame.
Of the 92 pools of mosquitoes tested, 30 had at least one mosquito that tested positive for California serogroup viruses. There has been one confirmed diagnosis of meningoencephalitis — a severe neurological condition — caused by the snowshoe hare virus. There have been no positive cases yet of West Nile Virus.
The Southeast Alaska Tribal Ocean Research program found that all shellfish species in Settler's Cove and Seaport Beach in Ketchikan and Starrigavan North beach in Sitka are affected by high levels of Paralytic Shellfish Toxin, posing the risk of Paralytic Shellfish Poisoning for consumers.
The community of Gambell fought a distemper outbreak among its dog population this spring and managed to squash the epidemic in its early onset. Distemper is a deadly disease that can afflict dogs and wildlife alike and also has been documented in the North Atlantic to jump from dogs to marine mammals like seals.
A recent spate of attacks on humans and pets by foxes in Topsham may be in part due to a new strain of rabies. As of April 18, there have been five such attacks in Topsham this year. State Veterinarian Michele Walsh theorizes a rabies strain more associated with raccoons has begun infecting gray foxes.
Nome and the surrounding area, including St. Lawrence Island, is fighting rabies almost as hard as it is fighting COVID-19. Because of the high level of rabies infection Fish and Game requested assistance from the National Rabies Management Response Program. Their job is to manage a wildlife disease outbreak. Several technicians and a rabies biologist are in Nome reducing the number of foxes.
The H5N8 virus was detected in sick and injured birds in February and early March this year, including in a swan found dead in Helsinki's Eläintarhanlahti park and a goshawk sent to Korkeasaari Wildlife Hospital from Kumpula. Several birds infected with avian influenza have been found in Uusimaa this winter.
The death of birds recently discovered in Tuolporn Taley Boeung Sne protected area in Prey Veng province’s Ba Phnom district was a result of bird flu caused by influenza A virus subtype H5N1 (A/H5N1), officials confirmed. Puth Bo, community chief in the Tuolporn Taley Boeung Sne area, said community members and specialists had collected and destroyed 135 bird carcasses, raising the total to nearly 2,000 since March 17.
The head of Alaska’s Wildlife Disease and Health Surveillance Program confirms that the City of Nome has a higher than normal case count of rabies in the red fox population. Usually in winter, most of the cases come from Prudhoe Bay and Utqiagvik. This winter most of the cases are from Nome, as well as from Kivalina and other villages around Kotzebue.
Bird flu, or avian influenza, has struck the Swedish poultry industry hard this winter. Since November, thousands of turkeys and more than one million chickens have been culled. Malin Grant, an epidemiologist at the National Veterinary Institute, says the virus can be deadly for domestic poultry but the strains currently circulating don't easily infect or spread between people.
The highly contagious infection can lead to pneumonia and hits puppies, older dogs and dogs with health problems the hardest. Vaccination against kennel cough protects for about year.
For years, researchers thought an infectious pathogen was behind sea star wasting disease. A new study found that multiple species of bacteria deplete oxygen from the water effectively suffocating sea stars. These microbes thrive when there are high levels of organic matter in warm water and create the low oxygen conditions.
After two foxes tested positive for rabies in Tuktoyaktuk, N.W.T., health officials are advising anyone who has come in contact with a fox to contact the local health centre and report the incident immediately.
The cause of death is almost certainly acute Aspergillosis, a respiratory tract infection caused by a fungus commonly found in soil, dead leaves, moldy grain, compost piles, or in other decaying vegetation. Wildlife managers say the die-off seems to have stopped, likely due to the fungus source no longer being available.
