#The Disquieting Delights Of Salt-Rising Breadas befits a nasty pathogen Clostridium perfringens grows aggressively. Its cells can divide every ten minutes a handful turning into trillions of hydrogen makers overnight.

A century ago a scientist went so far as to bake bread leavened with Clostridium perfringens drawn from an infected wound in

The realization that the salt-rising bacterium was a form of pathogen came in 1923 when a USDA microbiologist named Stuart A. Koser analyzed commercial salt-rising starters.

but it was implicated in gangrenous flesh wounds. So Koser checked to see whether bakery loaves of salt-rising bread contained any of the bacillus. Indeed they did but in the form of spores rather than live cells.

and found that they didn't cause gangrene. Koser then wondered if a known disease strain could grow well enough in dough to leaven it

and so pose a hidden hazard to the consumer. So he obtained a bacillus culture from the army that had originally been taken from a soldier's infected wound.

Less understandably he didn't test the wound-risen bread for toxicity. But his creepy experiment made clear that there were different strains of the bacillus with different toxicities

and'50s that scientists recognized Clostridium perfringens as a leading cause of foodborne illness as well as wound infections Since then they've found that there are at least five major types of the bacterium that produce different toxins and cause different kinds of disease.

and found that all of them contained strains of Clostridium perfringens type A the group associated with food poisoning rather than wound infection.

and the lack of any known cases of the bread causing illness Juckett and Mcclane concluded that it seems reasonable to continue the consumption of this delicious old-fashioned bread.

Two weeks ago at a conference in South africa scientists met to discuss how to contain a deadly banana disease outbreak in nearby Mozambique Africa.

The international delegation of researchers shared their own approaches to the malady hoping to arrive at some strategy to insulate Mozambique and the rest of Africa:

Worse he says the disease's rapid spread endangers banana crops beyond Mozambique s borders.

I originally reported on the malady that s now infecting the Mozambique plantation in the August 2005 print edition of Popular Science.

I described a fungus commonly known as Panama Disease but scientifically termed Fusarium oxysporum f. sp. cubensis Tropical Race 4 (or Foc-TR4).

When I reported on the disease which was and remains incurable it had spread only to a few Asian nations including Taiwan and Indonesia.

One big question is how the disease actually arrived in Mozambique. At the conference I attended participants offered two theories.

the malady is so virulent that a single clump of dirt on a shoe or a tool can lead to continent-wide infection.

Philippine banana growers have been struggling with Foc-TR4 since the 1990s and the workers in Mozambique were employed by Chiquita management and then by a company called Matanuska

Another idea is that the disease was waiting in the soil all along prior to the arrival of bananas in Mozambique.

Viljoen strongly believes those tests will show that the disease came from the Philippines. Whatever the origin it is certain that the new plantation was equipped poorly to handle the fungus.

Likewise infection from common irrigation sources was one of the primary ways the Gros Michel version of Panama Disease spread in the mid-20th century.

Another likely vector for the spread of the disease was local people walking across the farmland on their way home says Viljoen.

Just five years ago Chiquita s Aguirre told the Cincinnati Enquirer We believe that Panama Disease is limited a very threat

and that Panama Disease represents a long-term danger to the industry. The disease has also recently been identified in the middle East with crops stricken in both Jordan and Oman.

Loyd also confirmed that Chiquita is now researching a replacement banana for the Cavendish. One possibility is modified a version of the fruit developed in Taiwan;

but is highly resistant to Panama Disease. The variety is currently being tested in the Philippines

which every Cavendish plant is essentially a clone) to one with multiple resistant breeds would help insulate plantations against disease

when the disease will hit Latin america which grows the bananas we consume. Mozambique brings disturbing news on that front:

and even breast cancer cells and possess anti-malaria and antibacterial properties. The study found that chemicals isolated from fungi in three-toed sloths were deadly for parasites that cause malaria and Chagas disease (Plasmodium falciparum and Trypanosoma cruzi respectively.

The research was only a partial cataloguing of microbes that live in sloth fur which the scientists describe as a potential goldmine for drug discovery.

Very few chemicals have been found to have activity against Chagas disease for example and the drugs currently used to treat it are discontinued often due to their negative side effects.

Several of the chemicals isolated from the fungi also showed strong activity against human breast cancer cells. a

#100 Years Of Smoking Studies In Popular Sciencefifty years ago tomorrow then-U s. Surgeon general Luther Terry held a press conference announcing that among other ills smoking caused lung cancer.

the number of scientific studies the U s. surgeon general's advisory committee examined before declaring that smoking caused lung cancer laryngeal cancer and chronic bronchitis17. 7 million:

A chain-smoking doctor among Terry's expert report authors was diagnosed with lung cancer within a year of the surgeon general's announcement NPR reports.

He later died of the disease. 8 million: the estimated number of tobacco-related deaths in the U s. that anti-smoking initiatives have prevented since 196419.6:

At the same time there are hints throughout Popular Science's archives suggesting people knew that they should try to quit that evidence was accumulating for smoking's long-term harms

Fast-forwarding to the years preceding the 1964 surgeon general's report scientists were gathering more rigorous evidence that smoking causes various illnesses including lung cancer.

The U s. Public health Service for example has reported that among veterans who died from lung cancer over a certain period about 10 times as many had been smokers igarette smokers s nonsmokers.

USPHS has reported also that the death rate from coronary heart disease among cigarette smokers was almost two-thirds higher than the rate for nonsmokers.

Mounting evidence cited in the journal shows resistant pathogens are emerging in the wake of this veritable flood of antibiotics--resulting in an increase in bacteria that is immune to available treatments.

Modern medicine relies on antibiotics to kill off bacterial infections explains Hollis. This is incredibly important. Without effective antibiotics any surgery--even minor ones--will become extremely risky.

Cancer therapies similarly are dependent on the availability of effective antimicrobials. Ordinary infections will kill otherwise healthy people.

Bacteria that can effectively resist antibiotics will thrive Hollis adds reproducing rapidly and spreading in various ways.

#Biologists find clues to a parasites inconsistencytoxoplasma gondii a parasite related to the one that causes malaria infects about 30 percent of the world's population.

but a small percentage develop encephalitis or ocular toxoplasmosis which can lead to blindness. MIT biologist Jeroen Saeij and his colleagues are trying to figure out why some forms of the disease are so innocuous

while others ravage their victims. In their latest paper they analyzed 29 strains of the parasite

and found that some of those endemic to South america or atypical in North america provoke very strong inflammation in the cells they infect

and then you have these exotic strains that can cause very severe disease says Saeij the Robert A. Swanson Career Development Associate professor of Life sciences.

Infection rates vary around the world: In the United states it's about 10 to 15 percent

and Europe usually cause problems only in people with suppressed immune systems such as AIDS patients or transplant recipients although some atypical North american and European strains have been associated with severe ocular toxoplasmosis.

It can also be dangerous for a woman to become infected while pregnant as the parasite can cause birth defects.

In South america there is a much higher incidence of severe symptoms in otherwise healthy people. Scientists are still unsure

Hyperinflammatory responsein the new study which appears this week in the journal PLOS Pathogens Saeij

and host--are most active during infection. Most strikingly some South american and some atypical North american strains induced a type of immune reaction usually only seen during viral infection known as the type 1 interferon response.

This generates very strong inflammation in the host cells which the researchers suspect may be causing the severe effects produced by those strains.

#Diet rich in tomatoes may lower breast cancer riska tomato-rich diet may help protect at-risk postmenopausal women from breast cancer according to new research accepted for publication in The Endocrine Society's Journal

or delay around 8500 vascular deaths such as heart attacks and strokes every year in the UK--similar to giving statins to everyone over 50 years who is not already taking them--according to a study in the Christmas edition of The BMJ.

The research takes into account people who are already appropriately taking statins to reduce their risk of vascular disease

In the United kingdom lifestyle changes are recommended the first step to prevent heart disease. However trial data suggest that statins can reduce the risk of vascular events irrespective of a person's underlying risk of cardiovascular disease.

As such calls are being made for greater use of statins at a population level particularly for people aged 50 years and over.

However side-effects from statins mean that prescribing statins to everyone over the age of 50 is predicted to lead to over a thousand extra cases of muscle disease (myopathy) and over ten thousand extra diagnoses of diabetes.

This research adds weight to calls for the increased use of drugs for primary prevention of cardiovascular disease as well as for persevering with policies aimed at improving the nutritional quality of UK diets they conclude.

and that both drugs and healthier living can make a real difference in preventing heart disease and stroke.

#EU membership may have led to allergy increase in rural Polandpoland's entry into the EU may have had the surprising consequence of increasing allergies in rural villages according to a new study.

Surveys show that the prevalence of atopy a predisposition towards allergic reactions jumped from seven per cent to 20 per cent in villages in southwest Poland between 2003 and 2012.

Exposure to farm animals especially at a young age is thought to protect against developing allergies. The findings add to evidence that westernized lifestyles increase the risk of allergic diseases.

Previous research has suggested that farm dwellers especially children who grow up on farms have lower rates of hay fever

and atopy than people living in towns. Study author Professor Paul Cullinan from the National Heart and Lung Institute at Imperial College London said:

Asthma hay fever and other allergic diseases are becoming more common in many countries and there's growing evidence that they're linked to modern clean lifestyles.

We found that rapid changes in farming practices after Poland joined the EU were accompanied by a sharp increase in allergies over a very short period of time.

It's likely that similar changes are occurring in other places in Europe and we can expect that elsewhere in the world we may see major increases in allergies asthma

and hay fever over the coming decades as countries become more westernized and less rural. Researchers from Wroclaw Medical University and Imperial College London conducted surveys in villages and a small town in southwest Poland in 2003 one year before Poland joined the EU

and 2012 to study the prevalence of asthma hay fever and atopy which is diagnosed with a skin prick test.

In 2003 7. 3 per cent of villagers tested positive for atopy compared with 20 per cent of townspeople.

In 2012 the prevalence of atopy in villages had risen to 19.6 per cent. hay fever also rose from 3. 0 per cent to 7. 7 per cent

but the prevalence of asthma did not change significantly. In towns there were no changes in the prevalence of allergies.

Twenty-four per cent of village dwellers had regular or occasional contact with cows in 2003 but this fell to four per cent in 2012.

Thirty-three per cent had contact with pigs in 2003 but only 14 per cent in 2012.

#Legislation to provide allergy medication in schools crucial to save livesan act recently signed by President Obama will make it easier to provide epinephrine to children with severe food allergies in schools even without a prescription.

since up to 6 percent of children in the United states are diagnosed now with a food allergy.

Allergic reactions to food and other potential life threatening allergic reactions can be fatal unless epinephrine is injected into the child immediately.

or more students with a food allergy and about 25 percent of life-threatening food allergy reactions reported at schools occurred in children with no prior history of food allergies.

Epinephrine in schools should not replace your family's own individualized allergy treatment plan that you make with your allergist

Whether from cows goats or sheep raw milk and milk products are a continuing source of bacterial infections that are especially dangerous to pregnant women fetuses the elderly young children

and milk products said Maldonado an infectious disease expert who also is a pediatrician at Lucile Packard Children's Hospital.

But relative to the amount of raw-milk products on the market we do see a disproportionately large number of diseases and illnesses from raw milk.

From 1998 through 2009 there were 93 recorded outbreaks of disease resulting from consumption of raw milk or raw-milk products causing 1837 illnesses 195 hospitalizations and two deaths.

Most of those illnesses were caused by contamination of the product with E coli or with species of Salmonella or Campylobacter.

Infections by such bacteria can cause diarrhea fever cramps nausea and vomiting. Some infections can become systemic.

A 2011 survey by the National Association of State departments of Agriculture determined that raw milk and raw-milk products were legal to sell in 30 states

Before pasteurization was developed one of the major causes of childhood disease and death was drinking milk

It was not uncommon for children to contract tuberculosis from milk. Some advocates of raw-milk consumption argue that cows are healthier now than in the pre-pasteurization era

but Maldonado said that even in healthy herds there are other organisms that can cause serious bacterial infections in children and pregnant women.

or pregnant women they can cause severe illness. The academy's policy statement endorses a nationwide ban on the sale of raw

In addition to many species of bacteria the list includes giardia rabies and norovirus. According to the U S. Centers for Disease Control and Prevention norovirus is the most common cause of acute gastroenteritis in the United states causing 19-21 million illnesses

and contributing to 56000-71000 hospitalizations and 570-800 deaths annually. We invented pasteurization to prevent these horrible diseases Maldonado said.

There is really no good reason to drink unpasteurized milk. Story Source: The above story is provided based on materials by Stanford university Medical center.
