Salmonella Infection Mitigates Asthma

Researchers from Germany have identified the mechanism by which Salmonella infections can reduce the incidence of asthma in mice. The research, which appears ahead of print in the journal Infection and Immunity, opens up new avenues of research that could lead to treatments.

Incidence of alle... Read More

Bacteria in space!

Where humans travel, bacteria will follow. If people are in space for any amount of time, bacteria are sure to thrive there so it’s good to know that there are already researchers looking at how the environment within spaceships affects bacterial populations. Work done on planktonic colonies of ... Read More

TWiP 58 letters

Trudy writes:


Dear Vincent and Dickson,


Listening to TWiP on cyclosporiasis. Because I am all too aware of the possible contamination of many crops as a former public health nurse who worked in epidemiology for my state (Florida), I always wash my fruits and v... Read More

Hi Vincent and Dickson,


I enjoy TWIP, and often recommend it to my students. I'm a parasitologist, primarily a Leishmaniac, but I have learnt a lot from TWIP. I find it both more educational and entertaining than Car Talk.

TB bacteria mask their identity to intrude into deeper regions of lungs

TB-causing bacteria appear to mask their identity to avoid recognition by infection-killing cells in the upper airways. The bacteria call up more permissive white blood cells in the deeper regions of the lungs and hitch a ride inside them to get into the host’s body.

These findings are report... Read More

Researchers Find Rising Incidence of Patients Admitted With Infections Resistant To Common Antibiotics

The emergence of community-acquired infections, such as urinary tract infections (UTI), due to strains resistant to common antibiotics are on the rise, according to Rhode Island Hospital researchers. The study is published online in the journal Antimicrobial Resistance and Infection Control.

Fla. dolphins harbor potentially deadly bacteria

One in every three bottlenose dolphin tested in the Indian River Lagoon on Florida's Atlantic coast has antibodies to a bacteria that can make them more vulnerable to other deadly infections, according to a new study.

The finding comes as researchers struggle to figure out what has caused a r... Read More

Decades-old question: Is antibacterial soap safe?

It's a chemical that's been in U.S. households for more than 40 years, from the body wash in your bathroom shower to the knives on your kitchen counter to the bedding in your baby's basinet.

But federal health regulators are just now deciding whether triclosan — the germ-killing ingredient fo... Read More

Arctic Bacteria Thrives at Mars Temps

One of the things that makes it extremely hard for life to flourish in foreboding places like Mars and the moons of Saturn is the punishing cold. Without the benefit of a blanket-like atmosphere, these celestial bodies have average temperatures well below freezing. Now, researchers from McGill U... Read More

Gut Bacteria Play Key Role in Vaccination

The bacteria that live in the human gut may play an important role in immune response to vaccines and infection by wild-type enteric organisms, according to two recent studies resulting from a collaborative effort between the University of Maryland School of Medicine Institute for Genome Science...

New Research on Antibiotic-Resistant Bacteria, Pressure Ulcers, Severe Alcoholic Hepatitis, and More

Two million people suffer antibiotic-resistant infections yearly, and 23,000 die each year as a result. Most of these infections occur in the community, but deaths usually occur in healthcare settings. Cost estimates vary but may be as high as $20 billion in excess direct healthcare costs.

Why Do Bacteria Thrive in Space?

For reasons that still aren't well understood, bacteria proliferate in microgravity. Creating a potential recipe for disaster for humans stationed in space for long periods, bacteria's love of low-g also raises an intriguing question: Why are they so comfortable there?

A single amino acid change switches avian influenza H5N1 and H7N9 viruses to human receptors

Two back-to-back papers were published last week that provide a detailed analysis of what it would take for avian influenza H5N1 and H7N9 viruses to switch to human receptors. A single amino acid change in the viral hemagglutinin protein is sufficient to quantitatively change binding of the viru... Read More

Bacteria in Baby's Belly May Influence Growth, Study Says

Infants' early growth is influenced by the types of bacteria in their digestive system, a new study says.

A variety of bacteria quickly populate the sterile digestive tract of a newborn. Norwegian researchers identified connections between specific types of bacteria and infant growth rates.

TB or not TB: that is the question.

Tuberculosis (TB) represents a serious public health problem: 8.7 million cases in 2001 and over 1.4 million deaths per year. In 2006, extensively drug-resistant (XDR) tuberculosis has been confirmed in 84 countries, heralding the possibility of virtually untreatable tuberculosis. The emergence ... Read More

New chip lets scientists listen in on bacteria

Researchers at Columbia University are turning that optics-based imaging approach on its head, instead developing a chip based on integrated circuit technology that lets them not only electrochemically image bacteria, but listen in on them as well.

Bacteria 'could be a cause of preterm births'

New research from the US has found a link between preterm births where the water sac around the baby breaks prematurely, and bacteria near where the walls of the sac are thinner.

The researchers, including Amy P. Murtha, associate professor of obstetrics and gynecology at Duke University Scho... Read More

Poison-breathing bacteria

Buried deep in the mud along the banks of a remote salt lake near Yosemite National Park are colonies of bacteria with an unusual property: they breathe a toxic metal to survive. Researchers from the University of Georgia discovered the bacteria on a recent field expedition to Mono Lake in Calif... Read More

Bespoke microbiome therapy to manage plant diseases

In this paper we describe the perspective of following the achievements in medicine, where gut microbiome transplants are proving to be a powerful method to overcome several gastrointestinal disorders and many other physiological problems, to possible solve diseases in plants. There is strong si... Read More
