Recent studies have suggested that this parasite may actually contribute to human psychiatric disorders such as schizophrenia and obsessive compulsive disorder as well as other brain pathologies they added.#
The team was looking for priobiotic bacteria that could be fermented with sausage and would survive the acidic digestive tract such as the bacteria found alive in human feces.
So they turned to dirty diapers: They collected priobiotic bacteria samples from the diapers of healthy infants who were up to 6 months old.
Ultimately they made a kind of Mediterranean fermented pork sausage called fuet which included a strain of bacteria from infant feces.

#Ancient Parasite Uncovered in Mesopotamian Tomb Some of the earliest evidence of a human parasite infection has been unearthed in an ancient burial site in Syria.
The egg of a parasite that still infects people today was found in the burial plot of a child who lived 6200 years ago in an ancient farming community.
We found the earliest evidence for a parasite that causes Schistosomiasis in humans said study co-author Dr. Piers Mitchell a biological anthropologist at the University of Cambridge in England.
The parasite egg hails from the Fertile Crescent a region around the Tigris and Euphrates rivers in the middle East where some of the first irrigation techniques were invented about 7500 years ago.
That suggests that advances in farming technologies caused the rise of human infections with the waterborne worm Mitchell told Live Science. 7 Stunning Archaeological Sites in Syria Bloody worms Schistosoma parasites live in freshwater snails
In the middle East the parasite typically infects the blood vessels in the kidneys and can lead to blood in the urine anemia
The parasite can spread when eggs are shed in the feces or urine of infected people.
Agricultural technologies are tied to the parasite's prevalence experts say. Studies in Africa in modern times have shown that farming irrigation
The team collected samples of soil from around the skeletons'abdomens where the parasite would be expected to be found and also from around the feet and heads
which served as a control (eggs found there would suggest the soil at the site was contaminated with the parasite more recently).
The researchers sifted through the soil looking for particles that were the right size to be the parasite's egg just 0. 003 inches (0. 1 millimeter) in diameter Mitchell said.
and planting and the rivers'warm slow-moving water would have been an ideal breeding ground for the snail hosts of the parasite Stein said.
As follow-up work the team wants to analyze the genetic material from the parasite to see

Just as volcanic ash entombed the citizens of the ancient Roman city dental plaque preserved bacteria and food particles on the skeletons'teeth.
Researchers analyzed dental plaque from skeletons in a medieval cemetery in Germany and found that the mouths of these aged humans were home to many of the same bacterial invaders that cause gum disease in the mouths of modern humans.
The discovery of these bacteria also revealed clues to the dental hygiene and diets of these centuries-old humans according to the study detailed today (Feb 24) in the journal Nature Genetics. 5 Surprising Ways to Banish Bad
but it turns out to be a great time capsule for preserving the bacteria (or microbiome) and bits of food on the teeth of humans long after they die.
The sticky bacteria on teeth trapped particles of food and other debris and over time the calcium phosphate in saliva the same mineral found in bones
The team reconstructed the genome of a major bacterial pathogen and recovered some of the first evidence of food molecules from ancient dental plaque.
The microbe species found in the ancient plaque were remarkably similar to ones found in modern mouths the researchers said.
Gum disease is caused most often by the species Porphyromonas gingivalis Tannerella forsythiatreponema denticola and Filifactor alocis and these microbes were all present on the teeth of the skeletons with dental disease.
Gum diseases are caused usually by infections or inflammation of the gums and surrounding bone. About 47 percent of adults ages 30 or older in the United states have some form of gum disease according to the Centers for Disease Control and Prevention.
Radiation is known to have harmful effects on microorganisms such as bacteria and fungi. Recent research has found that radiation therapy can cause severe complications in cancer patients by reducing the populations of helpful bacteria in the intestines.

#Bacteria in Wine May Bring Health Benefits There are bacteria in wine that may be beneficial for people's health new research finds.
In the study researchers in Spain isolated 11 strains of bacteria from wine including strains of Lactobacillus
and Pediococcus bacteria which are associated with the wine-making process. Up to now many studies have reported that the best foods to deliver probiotics are fermented dairy products
so that the probiotic properties of wine-related Lactobacillus were studied hardly said study author Dolores Gonzã¡
Consuming probiotics may be beneficial primarily for maintaining a healthy community of gut bacteria and bowel function she said adding that probiotics have also been reported to possibly have anticancer and cholesterol-lowering properties.
In the study the researchers examined the ability of the bacteria they isolated from wine to survive in conditions similar to those found in the human gastrointestinal system.
Bacteria in any food product must to be able to survive in the hostile environment of the gastrointestinal tract
whether the bacteria in wine could survive when exposed to simulated gastric juice bile and lysozyme an enzyme that is highly concentrated in human saliva that can damage bacterial cell walls.
They found that the bacteria could survive in such conditions and their survival was comparable to
or even better than the survival of several strains of bacteria known to be beneficial to human health.
The investigators also looked at how well the bacteria in wine might stick to the walls of the human intestine by growing human intestine cells in a lab dish.
They found the bacteria did stick and therefore the bacteria may provide beneficial effects such as the exclusion of pathogens
or harmful bacteria from the intestine they wrote in the study. In particular one strain of bacteria found in wine called P. pentosaceus CIAL-86 had an excellent ability to stick to the intestinal wall
and good activity against E coli the researchers said. The probiotic properties of the lactic-acid bacteria isolated from wine are similar to those of probiotics that come from foods like dairy products such as fermented milk
or yogurt and dry sausages and foods of plant origin such as sauerkraut and olives fruits cereals meat or fish she said.
The new findings do not mean however that drinking a couple glasses of wine a day will provide the same health benefits as eating a food like yogurt she said.
Even though the moderate consumption of wine which she defined as two glasses per day may confer certain health benefits wine does not currently provide a sufficient amount of probiotics to be beneficial
because many of the bacteria are eliminated during a process called sulfating which stabilizes wine she said.
Sulfating is the process of adding sulfites which are used preservatives commonly in winemaking.)However probiotics could be isolated from wine
#Food safety Returns To Nature (ISNS) Outbreaks of foodborne diseases carried by bacteria can be a nuisance at best and deadly at worst.
Bacteriophages are viruses that specifically attack bacteria. These phages as researchers call them have evolved alongside bacteria
and become very good at what they do. Scientists are interested most in lytic phages viruses that inject their DNA into a bacterium
and then hijack the cell s machinery to make new copies of the virus. The copies eventually burst through bacterium s membrane killing it
and attack neighboring cells. Recently a team of researchers at Purdue University in West Lafayette Indiana developed a cocktail of different phages that was extremely effective against Escherichia coli o157:
H7 the pathogen that was estimated to have caused more than 63000 illnesses and 2138 hospitalizations between 2000 and 2008 in the U s. The researchers mixed a cocktail of three phages
They found that the combination eliminated over 99%of E coli O157: H7 on spinach stored at room temperature.
One product called Listshield sold by Intralytix controls Listeria monocytogenes and can be applied directly to poultry meat.#
#oeit s a microorganism the concept of putting a virus on foods is initially hard to swallow
they only target bacteria. It s highly unlikely that they will ever evolve to cause diseases for humans or animals.
The bacteria on the other hand are highly virulent.##oe Phages are not human pathogens. The bacteria are the human pathogens#said Paul Ebner a professor of animal sciences at Purdue
and the lead author of the E coli study. Sulakvelidze added that phage bio-control products are an alternative to chemical washes
and irradiation two mechanisms commonly used to kill bacteria in ready-to-eat food products. Phages are much more specific usually one phage targets only one species of bacteria.
They kill the pathogenic bad#bacteria while leaving the naturally occurring good#bacteria intact making a more nutritious product.
Researchers are also looking into ways to treat bacterial infections in livestock using phages but Sulakvelidze said that results from these tests are inconclusive so far.
However if phages prove successful in this way it would greatly reduce the need for antibiotics in livestock
and potentially eliminate the need to treat food products with phages. Naturally there is also a push to find a use for phages in humans.
Antibiotic resistance in bacteria is a crisis. According to the Centers for Disease Control and Prevention each year in the United states at least two million people become infected with bacteria that are resistant to antibiotics
and at least 23000 people die each year as a direct result of these infections.##Phages are a hopeful alternative.
Phage therapy was the big thing in the 19 20s and 30s#said Jason Gill a microbiologist at Texas A&m University in College Station who was involved not in the study.
But now that many bacteria are resistant to one or more antibiotics phages are making a comeback.
Bacteria can become resistant to phages as well. But one type of bacteria usually only develops resistance to one or two types of phages
which is why researchers use a cocktail. The probability that one type of bacteria can become resistant to multiple phages at once is extremely low according to both Gill and Ebner.
But numerous obstacles obstruct the path to phage therapy in humans in the U s. Regulations make phages difficult to patent.
or destroy the bacteria the fastest#said Ebner. Hope still abounds for phages though.##oethey re the most abundant organism you can find in nature.
because the germ and bran components of the grain remain intact which also means that it retains the nutrients from these components.

Instead makers likely fermented this cheese using microbes such as Lactobacillus and Saccharomycetaceae yeasts which are used commonly to make the still-popular fermented dairy beverage known as kefir.
and found that the chemical and bacterial composition matched the snacks buried with the mummies.
I remember thinking that bacteria was a bad word. It represented something that should be avoided at all costs.
In fact our intestines have more than 500 types of bacteria. Some are beneficial and some are not.
Our diet and lifestyle can help to keep the balance of good and bad bacteria in check.
One way to do this is to consume beneficial bacteria also known as probiotics. The World health organization defines probiotics as live microorganisms which
when administered in adequate amounts confer a health benefit on the host. Many studies have evaluated the potential health benefits of probiotic use
For example some research shows that two common types of beneficial bacteria Lactobacilli and Bifidobacteria may regulate cancer growth
Other work revealed that probiotics may enhance the effects of the vaccine against rotavirus vaccine the most common cause of severely dehydrating diarrhea in infants and children according to a 2008 study in the journal Vaccine.
Here are three ways to increase your body's beneficial bacteria-load naturally. 1. Eat more yogurt.
You may be wondering how beneficial bacteria can survive in your body. How do these microorganisms eat?
Well the answer is they eat what you eat. Your dietary choices can determine whether you feed the good bacteria or the bad ones.
Beneficial bacteria thrive on things like fiber while harmful bacteria thrive on sugars and alcohols.
So consume more fiber-packed foods such as leafy greens oatmeal and whole grains. Healthy Bites appears weekly on Live Science.
Deborah Herlax Enos is certified a nutritionist and a health coach and weight loss expert in the Seattle area with more than 20 years of experience.
Probiotics are microorganisms that have a beneficial effect on their host. They promote intestinal function
I asked a research scientist who had been investigating these microorganisms for some time if he believed they really improve gastrointestinal health and if so
when there are research companies around the world spending millions to create products containing patented strains of probiotic bacteria for targeting specific ailments.
But it was reported recently that probiotic bacteria found in common fermented foods such as yogurt can reach the gut in high numbers increasing the likelihood of beneficial effects from consuming these foods.
Although all this doesn t prove that probiotics confer a health benefit the study authors speculate that probiotic bacteria

Until now none of these three West african countries had experienced ever an Ebola outbreak let alone cases involving a type of Ebola virus that had been found only in faraway Central africa.
Ebola virus: 5 Things You Should Know In a new article published today (July 31) in the journal PLOS Neglected Tropical Diseases Bausch
The virus causing this outbreak is the deadliest type of Ebola virus. The Ebola virus has five species
and each species has caused outbreaks in different regions. Experts were surprised to see that instead of the Taã Forest Ebola virus which is found near Guinea it was the Zaire Ebola virus that is the culprit in the current outbreak.
This virus was previously found only in three countries in Central africa: the Democratic republic of the congo the Republic of the Congo and Gabon.
Zaire Ebola virus is the deadliest type of Ebola virus in previous outbreaks it has killed up to 90 percent of those it infected.
But how did the Zaire Ebola virus get to Guinea? Few people travel between those two regions
If Ebola virus was introduced into Guinea from afar the more likely traveler was a bat he said.
Even if the Ebola virus had been circulating in Guinea for some time animals carrying the virus or other pathogens are not usually in the vicinity of humans
This increases people's risk of exposure to Ebola virus in remote corners of the forest he added.
It is possible that drier conditions somehow influence the number or proportion of bats infected with the Ebola virus or the frequency of human contact with them.
