Microbial detection array detects plague in ancient human remains
(Phys.org) —Scientists who study past pandemics, such as the 14th century Black Death that devastated much of Europe, might soon be turning to an innovative biological detection technology for some extra ...
Human, soil bacteria swap antibiotic-resistance genes: study
Soil bacteria and bacteria that cause human diseases have recently swapped at least seven antibiotic-resistance genes, researchers at Washington University School of Medicine in St. Louis report Aug. 31 in Science.
Infectious disease may have shaped human origins, study says
An international team of researchers, led by scientists at the University of California, San Diego School of Medicine, suggest that inactivation of two specific genes related to the immune system may have ...
Bacteria have evolved a unique chemical mechanism to become antibiotic-resistant
For the first time, scientists have been able to paint a detailed chemical picture of how a particular strain of bacteria has evolved to become resistant to antibiotics. The research is a key step toward designing ...
Scientists identify a deadly tool in Salmonella's bag of tricks
The potentially deadly bacterium Salmonella possesses a molecular machine that marshals the proteins it needs to hijack cellular mechanisms and infect millions worldwide.
New vaccine hope in fight against pneumonia and meningitis
A new breakthrough in the fight against pneumonia, meningitis and septicaemia has been announced today by scientists in Dublin and Leicester.
Why sex with a partner is better (w/ Video)
(PhysOrg.com) -- OK, it takes two for human reproduction, and now it seems that plants and animals that can rely on either a partner or go alone by self-fertilization give their offspring a better chance for ...
New study offers novel insights into pathogen behavior
A new study by a team of researchers that includes University of Notre Dame scientists Joshua Shrout and Mark Alber provides new insights into the behavior of an important bacterial pathogen.
Probing bacterial resistance to a class of natural antibiotics
Antimicrobial peptides are a distinctive class of potent, broad-spectrum antibiotics produced by the body's innate immune system—the first line of defense against disease-causing microbes.
Study examines role of microbes, their effect on infectious disease dynamics in Sierra Nevada yellow-legged frog
The adult human body is made up of about 37 trillion cells. Microbes, mainly bacteria, outnumber body cells by 10 to 1. Increasingly, scientists recognize that this huge community of microbes, called the ...
Tick protein does the trick to fight infection
A protein in ticks that protects them against the cold could inspire a new class of antibiotics for humans, according to a Yale University study.
New insights in survival strategies of bacteria
Bacteria are particularly ingenious when it comes to survival strategies. They often create a biofilm to protect themselves from a hostile environment, for example during treatment with antibiotics. A biofilm is a bacterial ...
Epidemic outbreaks caused by environment, not evolution
Researchers have traced genetic changes in a bacterial pathogen over 450 years, and claim that epidemics of bacterial disease in human history may be caused by chance environmental changes rather than genetic ...
A bacterial ballistic system
Many pathogenic bacteria use special secretion systems to deliver toxic proteins into host cells. Researchers of Ludwig-Maximilians-Universitaet (LMU) in Munich have determined the structure of a crucial ...
