A parasite and a virus may be teaming up in a way that increases the parasite's ability to harm humans, scientists at the University of Lausanne in Switzerland and Washington University School of Medicine in St. Louis recently reported in Science.
When the parasite Leishmania infects a human,... Read More
Scientists in Japan have revealed how vancomycin dimers are effective against vancomycin-resistant bacteria.
Vancomycin, a glycopeptide antibiotic, is used to treat bacterial infections in cases when other antibiotics are ineffective. However, the development of vancomycin resistant enteroc... Read More
This photograph depicts the frontal view of a Petri dish within which fungal colonies of Trichophyton rubrum var. granulare had been cultured. Revealed is the colonial morphology, which in the case of T. rubrum is said to be waxy, glaborous, i.e., flat to cottony, and display from a frontal pers... Read More
This silent animation created for Evolution: "The Evolutionary Arms Race" follows the progression of antibiotic resistance. When a sick person takes antibiotics, the drugs begin to kill off the bacteria. But if treatment stops prematurely, it leaves some microbes alive -- the ones with mutations... Read More
Microsponges derived from seaweed are a key component of a tiny programmable chip designed to sniff out diseases such as HIV and cancer.
The microsponges are 280-micrometer beads of agarose, a cheap, common, lab-friendly material made from seaweed and often used as a matrix for growing live c... Read More
A type of human encephalitis – an infection of the brain – has been known to affect the indigenous people living in the Sakha Republic of Russia since the mid-1800s. The available clinical and epidemiological evidence suggests that the disease is caused by a pathogen, but proving this has been d... Read More
Stained using a fluorescent antibody (FA) technique, this photomicrograph revealed a positive result for this stained serum specimen from a suspected rubella patient.
Rubella virus is classified as a togavirus, genus Rubivirus. It is most closely related to group A arboviruses, such as easter... Read More
When New York City’s health department revealed last weekend that three people had contracted cholera, it was a reminder that the city is not just a world capital of arts, business and the like — but also of exotic diseases.
If a disease has cropped up in the world, there is a good chance it wi... Read More
Here’s yet another reason to marvel at microbes: Buried deep within Earth at temperatures and pressures that would kill most living beings, bacteria and other tiny organisms not only survive but apparently even coax the rocks around them to produce food.

This colorized scanning electron micrograph (SEM) depicted a flagellated Vibrio vulnificus bacterium; Mag. 26367x.
Vibrio vulnificus is a bacterium in the same family as those that cause cholera. It normally lives in warm seawater and is part of a group of vibrios that are called "halophilic"... Read More
Health Sciences Centre wants parents to take steps to prevent respiratory infections in newborns after seeing a jump in the number of infections.
Since mid-December, there have been 106 cases of respiratory syncytial virus (RSV) admitted to Children's Hospital, according to the Winnipeg Regio... Read More
Researchers have developed a “Social-IQ score” for bacteria, which may lead to new antibiotics and bacteria-based “green” pesticides for the agricultural industry.
While sequencing the genome of the pattern-forming bacteria, Paenibacillus vortex (Vortex), an international research team develo... Read More
A stockpiled vaccine designed to fight a strain of avian flu that circulated in 2004 can be combined with a vaccine that matches the current strain of bird flu to protect against a potential pandemic, researchers from Saint Louis University's Center for Vaccine Development have found.
The fin... Read More
Fear of infection helped drive a 50 percent decline in new cases of HIV in Zimbabwe from 1997 to 2007, said an international study published Tuesday in the United States.
The analysis of social factors that helped to halve what was once one of the worst AIDS epidemics in the world could offer... Read More
There are myriad routes to making car fuel from waste, using mix-and-match technologies assembled in novel ways, but none has worked yet on a commercial scale. On Wednesday, Ineos Bio, the subsidiary of a major international chemical firm, broke ground on a plant that aims to use yet another com... Read More
