Rather than phone books they sift through genetic codes from humans to bacteria and a lot in between.
This so-called horizontal gene transfer is quite common among bacteria and archaea as exemplified by antibiotic resistance.
When a specific bacterium develops a defense against some drug the corresponding gene can pass horizontally to others in the same colony.
A 2008 study in the journal Proceedings of the National Academy of Sciences (PNAS) found that 80 percent of the genes in bacteria were transferred horizontally at some point in the past.
and animals swallowed up other bacteria to form symbiotic relationships which eventually resulted in specialized cellular components such as mitochondria and chloroplasts.
He is remembered perhaps best for classifying life into the now-well-accepted domains of bacteria eukaryotes (plants animals fungi and protists) and archaea.
In such a scenario a bacterium would not actually have a history in its own right:
#How Cranberries Stop Bacteria in Their Tracks An old wives'tale might be held up by modern science:
In their research led by Nathalie Tufenkji a professor of chemical engineering they added cranberry derivatives directly to laboratory dishes growing two bacteria mostly commonly associated with UTIS Escherichia coli and Proteus mirabilis.
The cranberry didn't kill these bacteria but it did limit their ability to swim and thus spread.
This bacterium spreads by swimming in swarms. The colony can be relatively immobile but then suddenly grow elongated flagella whiplike appendages to propel them to a new region to inhabit. 6 Superbugs to Watch out For Tufenkji's group found that cranberry powder in a petri dish limited the growth of flagella
Moreover increased cranberry concentrations reduced the bacterium's production of an enzyme called urease which contributes to the virulence or severity of infection.
because P. mirabilis is the main bacterium behind UTIS caused by catheters in hospitals. Scientists think that P. mirabilis can migrate up the catheter into the urinary tract.
namely it still prevents bacteria from swimming and spreading on the catheter surface. Tufenkji's earlier work found that chemicals in cranberries called proanthocyanidins (PACS) similarly hindered the gene in E coli responsible for growing flagellar filament.
E coli is the bacterium most associated with nonhospital-acquired UTIS. Women in particular can pick up this bacterium from frequent sexual intercourse;
although unlike with a sexually transmitted disease the bacteria are usually already on the woman S1 Â
and sexual activity merely moves the bacteria toward the urethra. Immobilizing bacteria rather than killing it s a good thing Tufenkji explained.
Bacteria are less likely to develop resistance to a substance that only is hindering their movement as opposed to killing bacteria
and preventing them from replicating. The mechanism of action is very different from antibiotics which depend on killing the cells Tufenkji said.
Our work to date suggests that the bacteria cannot develop'resistance'to cranberry. What happens in the body
when one consumes cranberries remains a mystery. Scientists at the University of Rennes in Rennes France found that compounds in cranberries could block up to 80 percent of E coli from attaching to the cells lining the urethra in a laboratory setting.

#Trendy'Paleo'Diet May not Suppress Appetite The trendy paleo diet a plant-based diet inspired by the idea that human ancestors mainly consumed roughage may not be so good at suppressing appetite according to new research conducted on gut bacteria.
In the study researchers looked at gut bacteria taken from people and from primates called gelada baboons and found that bacteria fed with predigested grass produced a smaller amount of compounds called short-chain fatty acids
which trigger the production of appetite-reducing gut hormones compared with the bacteria fed with predigested potatoes.

and co-evolved bacterial species in their guts Moran says. In insects this doesn't always appear to be true many seem to have selected a set of bacteria taken up from the environment
and the bacteria can live in a range of habitats outside the gut she says. But in honeybees and bumblebees the gut is dominated by a small number of tightly related groups she adds.
Why? The primary reason seems to be that sociality social interactions gives a route for dependable transmission between individuals.
Apis mellifera the honeybee has a distinctive set of about eight symbiotic bacterial species some of which occur in other Apis species and in the related Genus bombus bumblebees.
Antibiotic resistance Moran's research has revealed that bacteria in the guts of honeybees are highly resistant to the preventive antibiotic tetracycline probably the result of decades of exposure to it because of its use by beekeepers to prevent bacterial diseases.
And the gut microbiota of U s. honeybees is a treasure trove of tetracycline resistance genes that have been transferred horizontally from other bacteria.

Experts Look at Foods'Bacteria & Health Claims The term probiotic is misused so often that a group of experts has taken a fresh look at what probiotics really are examined
Probiotics are thought generally of as the good bacteria in the body. Experts define probiotics as live microorganisms which confer health benefits
which bacterial species may have health benefits and what those benefits may be. But there's still enough confusion surrounding the concept of probiotics and
and consultant who was one of the experts on the panel as well as executive science officer for the organization that convened the panel. 5 Ways Gut Bacteria Affect Your Health
even if a bacterial species has the potential to offer health benefits it shouldn't be called a probiotic until the effects are demonstrated in studies.
This includes undefined bacteria present in fermented foods. For example there may be numerous species of bacteria in blue cheese
or kefir (a fermented milk drink) but it is more appropriate to call these products sources of live cultures rather than sources of probiotics the researchers said.
For example aged cheeses such as blue cheese contain a mix of bacteria. And although cheese makers likely use defined cultures of bacteria that include a known mix of species the microbial content of any given cheese isn't listed on the food's label
and in fact varies among samples of cheese she said. Blue cheese may have lots of really neat microbes in it

#Ethanol Production, Plagued by Yogurt Bacteria, Getting Viral Cure Elizabeth Summer is cofounder and chief science officer for Phage Biocontrol Inc. This article was prepared by the U s. National Science Foundation (NSF) for the American Institute of Chemical Engineers publication Chemical engineering Progress.
When fermenting corn to create ethanol lactic acid bacteria can contaminate the tanks and proliferate inhibiting the growth of ethanol-producing yeast.
The most common control measures chemical antimicrobials such as antibiotics do not eliminate the lactic acid bacteria.
With support from the U s. National Science Foundation (NSF our company Ecolyse Inc. based in College Station Texas is working to address this issue by developing products to treat bacterial contamination.
Over the years yogurt manufacturers have experienced episodes of widespread lactic acid bacteria-culture death due to the activity of a virus that attacks the bacteria.
The virus injects their DNA into bacterial cells replicating inside and then causing bacterial cell lysis (i e. bursting) to release progeny phages (viruses).
We are trying to harness the innate ability of that lactic acid bacteriophage to control unwanted lactic acid bacteria during ethanol fermentation.
Each type of virus or phage kills only one type of bacteria. This specificity makes the phages safe enough for human consumption;
indeed phages are present in many foods and natural environments. But this specificity also makes it challenging to find a suitable phage for a given situation.
The development of phage-based products begins with gaining a full understanding of the species of bacteria that cause a particular problem.
To identify the bacteria of concern DNA is isolated from the raw material of interest (corn mash in the case of ethanol production)
and then a molecular screening technique such as polymerase chain reaction (PCR) or DNA sequencing identifies the bacteria.
The bacteria are grown in the lab and then used as bait in what are known as phage hunts.
In a phage hunt a culture of the bacteria is spiked with an environmental sample thought to contain phages.
If any phage specific for that host bacteria are present they will grow and multiply in the sample increasing in concentration from about one particle per milliliter to over 10000 particles per milliliter after a day or so.
Once enough different kinds of phage are isolated they can be grown in liquid cultures of host bacteria to make the large volumes needed for industrial treatment.
when a phage lyses (ruptures) a bacterial cell. They are applied best at the beginning of the fermentation cycle;
A 10-or 100-fold reduction in lactic acid bacteria increases ethanol yields. An additional plus is that replacing antibiotics with phages during the fermentation process increases the marketability of the dried distillers-grain byproduct (the potential animal feed)
Developing phage products to control such bacteria during ethanol fermentation represents an attractive phage application in the larger picture of industrial microbiology.
Certain industrial sectors however experience chronic detrimental effects of bacterial contamination. For example the oil and gas industry faces staggering revenue losses due to product degradation by hydrogen sulfide consuming bacteria and the industry spends an estimated $7 billion per year for chemical biocide treatments.
Bacteria are implicated also in the corrosion of metal and concrete structures causing damage conservatively estimated to be about $82 billion per year.
Lactic acid bacteria is a relatively well-defined target so ethanol fermentation is a promising early application for phage control.
