Deadly parasite threatens California sea otters
Melissa Miller knew something was off when she began to examine a sea otter that had died in San Simeon, a coastal California town about halfway between San Francisco and Los Angeles, in the winter of 2020. Nearly all of the animal’s body fat was inflamed. “It felt like there were little bumps all through it,” she says—a condition the veterinary pathologist had never seen in her 25 years examining sea otters for the California Department of Fish and Wildlife. She also found unusual lesions in the pancreas and heart. When Miller looked at the sea otter’s tissues under a microscope, she spotted a familiar foe...

What Are Presentations of Neurocysticercosis?
Discussion Neurocysticercosis (NCC) is the most common parasitic CNS infection world-wide. It is caused by the larval stage of the pork tapeworm Taenia solium. It is endemic in Southeast Asia including the Indian Subcontinent, sub-Saharan Africa and Latin America. It is becoming more common in other areas of the world because of immigration and the overall ease of travel. The basic Taenia lifecycle is that humans eat un- or undercooked pork (pigs are the intermediate host) that is invested with the larvae called cysterici. The adult tapeworm forms in the human gastrointestinal tract and eggs are produced. Humans are the de...

Parasitic fungus that infects and kills spiders discovered in Brazil
Exclusive: rare purple organism preys on trapdoor spider in behaviour reminiscent of its ‘zombie’ relatives that feature in apocalyptic TV show The Last of UsScientists believe they have discovered a new parasitic fungus which preys on trapdoor spiders in Brazil ’s Atlantic rainforest.The rare organism, which is purple, belongs to a group of fungi that infect invertebrates and take over the host. A closeup image shows the fungus wrapped around the body of a trapdoor spider, poking out of the burrow from which the arachnid grabs insects.Continue reading... (Source: Guardian Unlimited Science)

Next-generation bed nets get major endorsement from World Health Organization
A new tool to fight the world’s deadliest animal—the malaria-carrying mosquito—may soon become more widely available. Yesterday, the World Health Organization (WHO) endorsed using a new kind of bed net treated with insecticides. It combines two chemicals to more effectively kill the mosquitoes that transmit the parasite that causes malaria, a disease that killed an estimated 619,000 people in 2022, most of them young children in sub-Saharan Africa. Insecticide-treated bed nets protect people from malaria in two ways. They prevent mosquitoes from reaching the person sleeping under the net, and they kil...

One of North America ’s most dangerous invasive species is hitchhiking on fish
Zebra mussels ( Dreissena polymorpha ) are one of the most catastrophic aquatic invasive species in North America. Native to Russia and Ukraine, these fingernail-size mollusks have spread around the world, often carried in ballast water—used to stabilize boats—as larvae, where they’ve caused billions of dollars of damage to fisheries, water treatment facilities, and other aquatic industries by clogging intake pipes and robbing nutrients from ecosystems. Now, researchers have discovered a new way they invade—by hitchhiking on fish. The scientists made the observation while assessing fish communities ...

Indigenous groups in the Amazon evolved resistance to deadly Chagas
Humans have evolved to have some remarkable superpowers. People can thrive at high altitudes, dive for long periods underwater, and even tolerate a glass of lactose-rich milk well into adulthood. Now, a new study of Indigenous peoples from the Amazon rainforest reveals one more such adaptation: a genetic resistance to the endemic parasite responsible for deadly Chagas disease. The study’s findings could help scientists develop desperately needed new therapies for the disease, which infects roughly 6 million people in Latin America and is a leading cause of death in the region. “This paper is very important,” sa...

Parasites that feasted on extinct Tasmanian tiger still exist
Parasites that once feasted on the extinct Tasmanian tiger, otherwise known as the Thylacine, surprisingly still exist today. One of these parasites, a species of flea, has managed to survive even though the last known Tasmanian tiger died in 1936. Thylacines were native to the Australian…#tasmanian #australian #tasmania #newguinea #mackenziekwak #hokkaidouniversity #aussie #thylacine #londonzoo (Source: Reuters: Health)
