In contrast to air, the ocean represents a benign environment for most living organisms: With the exception of some harsh marine environments, the means of physicochemical properties are generally not far off the optimum of most species and their fluctuations are moderate, rarely exceeding biolo...

Members of the bacterial phylum Planctomycetes (click here and here) inhabit a wide variety of environments throughout the world. What makes them special is that in the mind of some investigators they possess a mix of eukaryotic and prokaryotic structural attributes. Now that is something pretty... Read More
Transfer of antibiotic resistance genes among gram negative bacteria in sewage and lake water and easy access of these
bacteria to the community are major environmental and public health concern. The aim of this study was to determine transfer of the
antimicrobial resistance genes from resista... Read More
Purple bacteria contain pigments that allow them to use sunlight as their source of energy, hence their color. Small as they are, these microbes can teach us a lot about life on Earth, because they have been around longer than most other organisms on the planet. University of Miami (UM) physicis... Read More
Although seldom fatal, persistent infection by chikungunya virus (CHIKV) afflicts patients with joint pain lasting months or even years. This insect-borne virus has received relatively little scientific attention in the 50 years since its initial description in African patients, but researchers ... Read More

Professor Geoff McCaughan, head of the Liver Immunobiology Program at Sydney's Centenary Research Institute, says preliminary results of a newly developed oral treatment regime for liver transplant patients with Hepatitis C were showing promising results.
"We are starting to see some dramatic... Read More
Scientists have proposed adding copper nano-particles into food packaging materials on this basis that this could help prevent a variety of foodborne diseases.
It has been known for centuries that copper has antimicrobial properties. For example, it was observed in Roman times that water cont... Read More
In order to isolate, study and efficiently treat a bacterial outbreak, it is vital to be able to grow, store and identify the particular strains of bacteria that cause the disease. While this can be a fairly simple task in a well stocked laboratory, it’s a lot harder to achieve out in the field,... Read More
In addition to preventing unwanted pregnancies and the spread of sexually transmitted diseases, condoms may help good bacteria in the vagina flourish, a new study from China shows.
Sexually active women in the study who used condoms had larger colonies of beneficial microbes in their vaginas ... Read More
In recent century, because of excessive use and abuse of antibiotics both in community and hospitals gram negative and positive bacteria are adapted on to this hostile environment and many strains (Clones) are exhbiting resistance to multiple antibiotics (MDR). These strains are widely distribut... Read More

Emergence and dissemination of antibiotic resistance plasmids are major concern for hospital care system and
increases the cost and decreases effectiveness of available antibiotics used in treatment of hospitalized patients.
In this study two Pseudomonas aeruginosa, two Escherichia coli, and a... Read More
Bacterial infections may play a role in triggering pancreatic cancer, according to recent research.
A growing number of studies suggest a role for infections --primarily of the stomach and gums -- in pancreatic cancer. The disease is a particularly deadly cancer, which the American Cancer Soc... Read More
You may never need to put fertiliser on your plants again.
Scientists have invented a technology that allows plants to fertilise themselves by obtaining nitrogen from the air.
Almost all plants rely on nitrogen from the soil to grow, but few are able to use it directly from the air and so ... Read More
The ice cream and caramels are delicious, but it's the brioche that really convinces you eating algae could be a winning idea. The oily, yellow, flour-like residue of wrung out algae—dubbed "algalin" by its marketers—can easily replace the butter and eggs in prototypical French pastry bread.

The new Mers virus, which has killed half of those infected, is "unlikely" to reach the same scale as Sars, ministers in Saudi Arabia say.
Most of the 90 Mers cases reported so far have been in Saudi Arabia.
Mers is from the same group of viruses as the common cold and Sars, which killed 7... Read More
It takes a “group effort” of genetic mutations to give organisms the best shot at evolutionary survival, a new study suggests.
Evolution occurs when an individual experiences a spontaneous beneficial mutation in its genome that improves its ability to adapt to its environment. The common view... Read More
Public-health officials discount role of sex in people's response to flu and other infections.
Sabra Klein came to the annual meeting of the Society for the Study of Reproduction this week armed with a message that might seem obvious to scientists who obsess over sex: men and women are differ... Read More
