Neonatal meningitis: the immaturity of microbiota and epithelial barriers implicated

Meningitis is associated with high mortality and frequently causes severe sequelae. Newborn infants are particularly susceptible to this type of infection; they develop meningitis 30 times more often than the general population. Group B streptococcus (GBS) bacteria are the most…

‘Smart collar’ could prevent tapeworms in dogs

Dogs infected with echinococcosis play a major role in spreading tapeworms across human populations around the world. Now, researchers have developed a “smart collar” which gradually delivers a steady dose of a deworming drug to dogs. The collar successfully reduces…

Microscopic CCTV reveals secrets of malaria invasion

State-of-the-art video microscopy has enabled researchers at WEHI, Australia, to see the molecular details of how malaria parasites invade red blood cells – a key step in the disease. The researchers used a custom-built lattice light sheet microscope – the…

Optimizing immunization with Sanaria® PfSPZ-CVac malaria vaccine

ROCKVILLE, MD, USA – June 8, 2021 – The PfSPZ malaria vaccines of Sanaria Inc. are unique in vaccine development as they are composed of weakened (attenuated) forms of the live parasite cells that cause malaria. These parasite cells are…

Beneficial arthropods find winter sanctuary in uncultivated field edges, study finds

CHAMPAIGN, Ill. — Many species of ground-dwelling beetles, ladybugs, hoverflies, damsel bugs, spiders and parasitic wasps kill and eat pest species that routinely plague farmers, including aphids and corn rootworm larvae and adults. But the beneficial arthropods that live in…

Malaria parasite’s partiality for the spleen

The malaria parasite Plasmodium vivax may accumulate in the spleen soon after infection to a greater extent than its better-known relative P. falciparum, according to new research published by John Woodford of the University of Queensland, Brisbane, Australia and colleagues…

Soybean cyst nematode is the most damaging soybean pathogen–and it’s rapidly spreading

The soybean cyst nematode (SCN) is the most damaging pathogen of soybean in the United States and Canada and it is spreading rapidly, according to information compiled by Gregory Tylka and Christopher Marett, nematologists at Iowa State University. SCN was…

What is killing bald eagles in the U.S.?

Bald eagles, as well as other wildlife, have been succumbing to a mysterious neurodegenerative disease in the southern United States since the 1990s. New research by the Martin Luther University Halle-Wittenberg (MLU) in Germany and the University of Georgia, USA,…

New discoveries on deadly fungus – might be a key for treatment

Aspergillus fumigatus kills as many people as malaria and tuberculosis, but is less known. It is found “everywhere”, for example in the soil or in our compost, but is not normally dangerous to healthy people. Those who die from it…

Dogs infected with Leishmania parasites smell more attractive to female sand flies

Dogs infected with the Leishmania parasite smell more attractive to female sand flies than males, say researchers. The study published in PLOS Pathogens is led by Professor Gordon Hamilton of Lancaster University. In Brazil, the parasite Leishmania infantum is transmitted…

Parasites may make dogs smell good to insect vector

The protist parasite Leishmania infantum can alter its host’s odor to attract female sand flies, which transmit the pathogen, according to a study published March 18th in the open-access journal PLOS Pathogens by Monica Staniek of Lancaster University and Gordon…

Artificial light affects plant pollination even during the daytime

The use of artificial light at night around the world has increased enormously in recent years, causing adverse effects on the survival and reproduction of nocturnal organisms. Artificial light at night interferes with vital ecological processes such as the nighttime…

Blight may increase public health risk from mosquito-borne diseases

Louisiana State University researchers recently published findings that blight leads to an increased abundance of disease-carrying mosquitoes. The researchers investigated the presence of several mosquito species in two adjacent but socio-economically contrasting neighborhoods in Baton Rouge: the historic Garden District,…

Agents of food-borne zoonoses confirmed to parasitise newly-recorded in Thailand snails

Parasitic flatworms known as agents of food-borne zoonoses were confirmed to use several species of thiarid snails, commonly found in freshwater and brackish environments in southeast Asia, as their first intermediate host. These parasites can cause severe ocular infections in…

Nobody finds the Alzheimer’s Germ in $1 Million Challenge, but eight researchers split $200K, says Dr. Leslie Norins of Alzheimer’s Germ Quest

There is now keen interest in deeper investigation of infectious agents as the trigger of Alzheimer’s disease
