Stress depression and the heart Previous studies have found that both stress and depression are linked with higher risk for obesity and heart problems.

In addition stress and depression have been linked to metabolic syndrome a condition that involves a number of risk factors for heart disease stroke and diabetes.

In the study the researchers also found that having had depression in the past worsened the effects of stress.

These meal-related effects of depression and stress could help explain why depression is linked to heart problems the researchers said.

To minimize the effects of stress on weight gain Kiecolt-Glaser suggests choosing vegetables fish and chicken over a hamburger and fries.

However some strains of TB may have already been lurking in South america a new study finds.

In fact these strains may have been brought to The americas by seals and sea lions researchers say. A new analysis of three ancient Peruvian human skeletons that date to between A d. 1028 and 1280 well before Europeans landed on American shores shows evidence of tuberculosis including skeletal lesions

However when the researchers reconstructed the genomes of the tuberculosis samples they found the strains didn't fit into any branches of the disease that are associated commonly with human infection.

Instead it was branching with the animals'strains of TB Bos told Live Science. The new study also suggests that the common ancestor of the M. tuberculosis complex is just 6000 years old

These dates are worked out by measuring the amount of genetic diversity among all known strains of TB bacteria

But with only three human skeletons it's unclear whether the seal strains of tuberculosis infected many people or just an isolated few.

whether the strains transmitted from seals and sea lions were widespread in the early Americas experts agreed.

Regardless of their age the marine tuberculosis strains appear to have been replaced completely by European strains following contact Bos said.

This timeline will be updated continually with key dates, drawing on authoritative information from the World health organization (WHO), the US Centers for Disease Control and Prevention (CDC) and other sources.

and pigs, making it more likely to reassort into a deadlier strain, they say. Pig surveillance is largely the remit of animal health organizations, agriculture ministries and the farming industry.

and his colleagues concluded that the lack of systematic swine surveillance allowed for the undetected persistence and evolution of this potentially pandemic strain for many years.

The virus originated from a mixture of swine flu strains, and pigs are an obvious part of the epidemiology of the new virus,

the three most common endemic strains are H1n1, H1n2 and H3n2. Most expected that any new pandemic would involve the introduction of a viral subtype not previously seen in humans,

is key to identifying possible pandemic strains and their future evolution. Yi Guan of the University of Hong kong, Robert Webster of St jude Children's Research Hospital in Memphis, Tennessee,

The results run counter to previous hypotheses that the human 1918 flu strain had evolved directly from a bird flu virus2.

Instead, the new findings suggest that an avian strain entered pig and human populations, and then swapped genes with mammalian flu viruses before becoming a pandemic.

Results from 1918 and 1957 pandemic flu suggest that public-health authorities should track the sequences of all influenza virus genes in emerging strains

'One of the many unusual characteristics of strain O104: H4 is that it has resistance genes to multiple classes of antibiotics.

and new pathogenic bacterial strains emerge. Shiga toxins have been causing diarrhoeal disease in humans for centuries the bacterial genus Shigella

including many strains of E coli. We are seeing more and more Shiga-toxin-producing strains says Alison Weiss, microbiologist at the University of Cincinnati in Ohio.

How have Shiga-toxin-producing phage spread so widely in just a few decades? Allison says they have unusual characteristics that make them very successful.

Not only are more E coli strains being infected with Shiga toxin, but it seems to be moving into different classes of bacteria.

The genome of strain O104: H4 has been sequenced, and it shares many genes with enteroaggerative E coli (EAEC) strains.

EAEC strains are associated not typically with zoonotic infections, and EAEC and Shiga toxin is a very unusual combination,

says Caprioli. This increased movement of Shiga-toxin-producing phage means that even more unusual and dangerous strains could be on the horizon.

Nature Newsthe bacterium responsible for the current outbreak of enterohaemorrhagic Escherichia coli (EHEC) infections in Germany is a strain that has never before been isolated in humans.

and have found clues as to how this strain which has infected so far more than 1, 500 people and killed 18 is making so many people ill.

This strain has never been found in any animal, so it is possible that it could have come from straight from the environment into humans.

Some strains of bacteria may have evolved resistance to tellurium during its historical medical use, or after its use in the mining and electronics industries increased its presence in the environment.

According to Wieler, the strain's resistance characteristics could point towards an environmental source, such as water or soil.

The ongoing genetic characterization of the strain might also reveal why the bacteria is mostly infecting adults,

But he suspects that the strain might have biological characteristics that make adults more susceptible to the infection.

One telltale sign is that the strain does not contain the eae gene, which codes for a protein called intimin,

Gad Frankel, a microbiologist at Imperial College London, suspects that the genome of this strain will reveal more information about the adherence mechanisms of E coli.

It is possible that the strain has evolved a combination of adhesion proteins that makes it particularly hard to remove from food,

This outbreak has shown we need to be prepared to deal with emerging strains with properties that give them enhanced virulence
