Neanderthals may have been infected by diseases carried out of Africa by humans

A new study suggests that Neanderthals across Europe may well have been infected with diseases carried out of Africa by waves of anatomically modern humans, or Homo sapiens. As both were species of hominin, it would have been easier for pathogens to jump populations, say researchers. This might ... Read More

Canadian innovation for killing mosquito eggs could help Zika fight

Toronto, Canada - With Canadian Government funding, a team of innovators from Canada and Mexico have successfully tested a low cost, environmentally-friendly way of destroying the eggs of the mosquito genus that spreads dengue, and likely spreading the Zika virus. Read More

Typhoid toxin increases host survival and promotes asymptomatic infection

Genotoxins damage the genetic material in cells and can cause mutations and cancer. Some bacteria code for and produce genotoxins. A study published on April 7th in PLOS Pathogens reports the surprising finding that one of them, typhoid toxin, actually increases survival of the infected host and... Read More

'Self-sabotage' prevents immune protection against malaria

Australian scientists have for the first time revealed how malaria parasites cause an inflammatory reaction that sabotages our body's ability to protect itself against the disease. Read More

Certain herpes viruses can infect human neurons

PHILADELPHIA - For years, researchers have noted a tantalizing link between some neurologic conditions and certain species of the herpes virus. In patients with Alzheimer's disease, multiple sclerosis, and cerebellar ataxia, among other neuropathies, the cerebrospinal fluid teems with Epstein-Ba... Read More

Experimental dengue vaccine protects all recipients in virus challenge study

A clinical trial in which volunteers were infected with dengue virus six months after receiving either an experimental dengue vaccine developed by scientists from the National Institutes of Health (NIH) or a placebo injection yielded starkly contrasting results. All 21 volunteers who received th... Read More


The standard practice of treating infections with the highest tolerable dose of antibiotic medications may not always be best way of preventing the evolution of drug resistance, a new study suggests. Read More

Deep sea microbes may be key to oceans’ climate change feedback

Microbes are hardly the poster-children of climate change, but they have far more impact than polar bears on Earth’s carbon cycle – and therefore on our climate. A new study published Friday in Science Advances finds that seabed bacteria and archaea (which look like bacteria but have very differ... Read More

Inheritable bacterium controls Aedes mosquitoes' ability to transmit Zika

Aedes mosquitoes carrying the bacterium Wolbachia--found inside the cells of 60 percent of all insect species--are drastically less able to transmit Zika virus, say researchers at Brazil's Oswaldo Cruz Foundation (FIOCRUZ) in a study published May 4 in Cell Host & Microbe. Read More

New anti-inflammatory agents can control inflammatory responses to fungal infection

The most frequent fungal threat to humans, Candida albicans, is a common cause oral and genital infection. The fungal infections are often worsened by overwhelming inflammatory responses in the body and cause high mortality among risk groups. Umeå University doctoral student Ava Hosseinzadeh has...

Colonies in isaw (grilled chicken intestine)

One of our class experiments include the analysis of grilled chicken intestine (isaw) under potato dextrose agar. Isaw is one of the most famous streetfood in the Philippines. And by popularity, it is also a sanctuary for yeasts and molds. The photo shows how these microorganisms formed beautifu... Read More

Experimental immunotherapy zaps 2 most lethal Ebola virus strains

January 13, 2016--(BRONX, NY)--Researchers at Albert Einstein College of Medicine and the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID) have engineered the first antibodies that can potently neutralize the two deadliest strains of the virus that causes Ebola hemorrhagic ...

Unknown organism, presumable yeast, seen on Bile Esculin Agar (BEA) after several months at refrigerated temperatures. Organism was mucoid.circular, and a light brown in color. The brown coloration around the colony indicates the organism can to convert the esculin into 6,7-dihydroxy-couarin p... Read More

A 'tropical' parasitic disease emerges in the Canadian Arctic

Montreal, April 28, 2016 - An outbreak of an intestinal parasite common in the tropics, known as Cryptosporidium, has been identified for the first time in the Arctic. The discovery was made in Nunavik, Quebec, by a team from the Research Institute of the McGill University Health Centre (RI-MUHC... Read More

Parasites help brine shrimp cope with arsenic habitat contamination

Artemia (the scientific name of the small crustacean that is also commonly known as 'sea monkey') is famous for being able to live in extreme environments and has become a model organism used to test the toxicity of chemicals in water. In addition, Artemia can produce dormant eggs, known as cyst... Read More
