Inside the connection between bacterial toxins and obesity

Scientists have made a connection between bacteria that reside in the human gut (specifically toxic by-products) and obesity. The research adds to the body of work about the microbiome.

Curing citrus greening with lasers

Tampa - A new method for tackling the serious citrus greening disease has been proposed. This involves powering a laser beam towards citrus leaves. Initial trials have proved successful.

Rats pose serious health threat to people and poultry

Vancouver - Rats pose serious health threats to communities and farms, according to a new study. This is because rats readily pick up diseases from one environment and spread them to another. Most at risk are humans and poultry.

Do our bodies really have more microbes than human cells?

Pick up a text book on microbiology or human physiology. Chances are you’ll stumble across a reference to the number of microorganisms in the human body exceeding the number of cells ten-fold. But is this correct?

Helping California's grape and wine industries with vine disease

San Fransisco - Researchers have pinpointed how Pierce's disease is transmitted from insects to grapevines. The disease costs California's grape and wine industries in excess of $100 million each year.

Exercising early changes gut microbes for the better

A new study has found how exercising while younger alters the types of gut microbes so that the composition is different than a person who takes up exercise later in life. These changes to the gut microbiome are beneficial.

Treating heart disease through the gut

Scientists have shown that focusing on microorganisms within the human gut could be the answer to prevent a type of heart disease associated with diet.

Men and women deposit different types of bacteria

The types of bacteria found in the home vary according to whether more men or women live in the house, as well as whether household pets are present.

Do antibiotics to treat MRSA make patients sicker?

New evidence suggests certain antibiotics intended to treat patients with MRSA infections are actually causing more harm than good.

University receives funding to tackle antimicrobial resistance

Loughborough - Loughborough University has received $750,000 of funding to explore the issue of bacterial resistance to antibiotics and to look for new candidate compounds to use as antimicrobials.

New class of bacteria busting antimicrobials

A new type of spiral polypeptides, produced at the University of Illinois, may signal a new type of antimicrobial. The polypeptides target the outer membrane of the bacterial cell wall.

New tick-borne illness discovered

A new, as yet unnamed, tick-transmitted illness has been discovered and it has close similarities with Lyme disease, including triggering fever.

Two-thirds of antibiotics are needlessly prescribed

London - A new report, aimed at the U.K. but applicable to most parts of the developed world, has concluded that around two-thirds of antibiotics are unnecessarily prescribed and are of no effect.

Anthrax case confirmed on British farm

A cow which died in the British country of Wiltshire has been confirmed as having been infected with anthrax bacteria. The risk to public health is described as low.

U.K. seeking antibiotic guardians

London - The British government is seeking healthcare professionals and members of the public to become "antibiotic guardians." This is to help with using antibiotics more wisely and helping to conserve stocks.

Heater-cooler devices could be a risk to some patients

Washington - U.S. Food and Drug Administration (FDA) has posted a safety note relating to the risk of bacterial infections to some patients placed close to operating heater-cooler devices.

Can bacteria block HIV infection between mother and child?

Women with HIV can pass on the virus to their children when they are pregnant. This doesn’t happen in all cases and one reason could be composition of vaginal bacteria.

Wastewater may not trigger antibiotic resistance

Copenhagen - Some scientists have been concerned that wastewater, where bacteria and antibiotics mix, could be seeding an increase in antibiotic resistance. A new study puts forward evidence that this is not the case.

Special coating developed to protect medical implants

Infections from medical implants are rare but they can still occur. In order to safeguard devices from bacterial contamination, researchers have developed a special biofilm coating.

Rapid tuberculosis test in development

In a new study, scientists have described the accuracy of three new rapid tests designed to detect drug-resistant forms of tuberculosis.

Antibiotic-resistant gonorrhea high in U.K.

Leeds - Multi-drug-resistant gonorrhea, a sexual health disease, is spreading in the north of England, with a focal point centered in the city of Leeds.

Fecal transplant success against pathogenic bacteria

A study in mice has shown that two common antibiotic-resistant bacteria can be reduced to a safe level via fecal transplantation of ‘healthy’ gut bacteria from a donor.

Warnings issued for U.S. food safety month

Washington - September is National Food Safety month, although many of the issues raised are pertinent not only to the U.S. but also to most countries worldwide.

Bacteria help deliver fish-oil diet benefits

Diets rich in fish oil compared with diets where lard is the predominant fat lead to very different types of bacteria being found in the guts. The bacteria appear to help with the health benefits of fish oil and the harmful effects of lard.

Insect chitin could have antimicrobial properties

A new study suggests chitin, a biopolymer extracted from insects and crustaceans, could be effective against pathogenic microorganisms.

GSK plant closes due to Legionnaires' disease

A GlaxoSmithKline facility has shut down due to a risk from Legionnaire's disease. The bacterium was detected in a cooling tower. The pharma plant makes inhaled medications.

Gut bacteria could prevent type 1 diabetes

Through an investigation of the immune response, researchers have discovered that certain bacteria can protect against the development of type 1 diabetes.

Discovering how Listeria grows on refrigerated salmon

Listeria monocytogenes, in sufficient numbers on refrigerated food, can present the serious risk of listeriosis. Researchers have been investigating the growth mechanism of the bacterium to find a way of reducing infection rates.

Bacterial solution to giving up smoking

A newly discovered strain of bacteria could be the solution for people wanting to break the nicotine habit. Specifically an enzyme extracted from the organism could be the basis of a new drug.

Hand washing is key to reducing infection risks

London - A new Internet educational series, designed to encourage people to wash their hands more often, should lower the risk of catching and passing on infections. This is the finding of a new medical survey.
