Monitoring rise and fall of the microbiome
Close analysis of bacteria in the human digestive tract reveals links to diet and other lifestyle factors, researchers report. Trillions of bacteria live in each person's digestive tract. Scientists believe that some of these bacteria help digest food and stave off harmful infections, but their role in human health is not well understood.

Smartphone experiment tracks whether our life story is written in our gut bacteria
Life events such as visiting another country or contracting a disease cause a significant shift in the make-up of the gut microbiota -- the community of bacteria living in the digestive system, according to. Two participants in a recent study used smartphone apps to collect information every day for a year. The authors think the method could be rolled out to studies of human-bacteria relationships with many more participants.

Bacteria manipulate salt to build shelters to hibernate
For the first time, researchers have detected an unknown interaction between microorganisms and salt. When Escherichia coli cells are introduced into a droplet of salt water that is left to dry, bacteria manipulate the sodium chloride crystallization to create biomineralogical biosaline 3-D morphologically complex formations, where they hibernate. Afterwards, simply by rehydrating the material, bacteria are revived. The discovery was made by chance with a home microscope.

Microbes make the sake brewery
A sake brewery has its own microbial terroir, meaning the microbial populations found on surfaces in the facility resemble those found in the product, creating the final flavor according to research. This is the first time investigators have taken a microbial census of a sake brewery.

Linking microbial, immune environment in semen to HIV viral load, transmission
HIV infection re-shapes the relationship between semen bacteria and immune factors which in turn affects viral load, suggesting that the semen microbiome plays a role in sexual transmission of HIV, researchers report. While HIV is found in many body fluids, sexual transmission through semen is the most common route of infection.

Newly discovered gut virus lives in half the world's population
Odds are, there's a virus living inside your gut that has gone undetected by scientists for decades. A new study has found that more than half the world's population is host to a newly described virus, named crAssphage, which infects one of the most common gut bacterial species, Bacteroides. This bacterium thought to be connected with obesity, diabetes and other gut-related diseases.

Detecting Salmonella in pork meat processing: New methods
Infections caused by foodborne microorganisms are an increasing public health burden. In a PhD project, new methods of characterizing and dectecting foodborne illness-causing Salmonella in pork meat processing and in bacteria in water, feed and food samples were studied.

One route to malaria drug resistance found
Researchers have uncovered a way the malaria parasite becomes resistant to an investigational drug. The discovery also is relevant for other infectious diseases including bacterial infections and tuberculosis. Fosmidomycin, an antibiotic, is being evaluated against malaria in phase 3 clinical trials in combination with other antimalarial drugs.
