Mongrel dogs that live amongst the rural poor may hold the key to controlling Chagas disease, a condition affecting 10 to 12 million people in Latin America, killing more than 15,000 a year.
Chagas disease is caused by the parasite Trypanosoma cruzi that is transmitted by the triatomine insec... Read More
A "malaria-proof" mosquito has been created by scientists who have engineered a genetic "on" switch that permanently activates a malaria-destroying response, according to their report in the journal Public Library of Science Pathogens.
If these mosquitoes are successfully introduced into the... Read More
In all organisms, RNA synthesis is carried out by proteins -- known as RNA polymerases (RNAPs) -- that transcribe the genetic information from DNA in a highly-regulated, multi-stage process. RNAP is the key enzyme involved in creating an equivalent RNA copy of a sequence of DNA. This transcripti... Read More

It’s not just the bugs in our guts that are surprisingly friendly. It’s our viruses, too.
After slowly coming to appreciate the importance of symbiotic bacteria for running our bodies, scientists have wondered whether viruses also help. Now a gene-hunting expedition in the gut has found it te... Read More
Next generation sequencing is a powerful method increasing in popularity for use in metagenomic and transcriptomic analysis in environmental microbiology. Compared to Sanger sequencing, next generation allows for sequencing of the complete genomic content of a sample without the need to make clo... Read More
The number of naturally occurring microbes that eat methane grew surprisingly fast inside a plume spreading from BP's ruptured oil well, an oceanographer who was one of the first to detect the plumes said Tuesday.

Many doctors suggest that whole cow's milk be avoided in the early months of an infant's feeding. Lactation specialists go even further, counseling "mother's milk only" until baby starts eating solid food. But new research from Tel Aviv University says that mothers who feed their babies cow's mi... Read More
At least 18 months of treatment are required to cure an infection of the heart lining or valves resulting from Q fever, and an additional six months will most likely be required if the patient has a prosthetic valve, researchers reported Wednesday. The findings have relevance because of the cur... Read More
There is a clear link between the use of antibiotics in livestock and drug resistance in humans, President Barack Obama's administration says, a position sharply at odds with agribusiness interests.
The Agriculture Department "believes that it is likely that the use of antimicrobials in anima... Read More
I was googling the internet after listening to TWiP 9 where there was a mention of the tongue parasitic isopod. From the looks of this published paper, that is the real deal. http://www.idosi.org/wjfms/wjfms1(2)09/10.pdf

Global fish farming may be the solution to the impending collapse of the commercial fishing industry, but penned fish are susceptible to infectious diseases. Infection with salmon infectious anemia virus, an orthomyxovirus, lead Wal-Mart to stop buying farmed salmon from Chile, the world’s secon... Read More
Waterborne illnesses are far from eradicated, and they're more than just a case of diarrhea. Americans shell out an estimated $500 million in health care costs to treat the conditions each year, according to a new report from the Centers for Disease Control and Prevention.
In a study presente... Read More
In the latest exploration into the universe of organisms inhabiting our bodies, microbiologists have discovered new viral genes in faeces. They find that the composition of virus populations inhabiting the tail ends of healthy intestines (as represented in our stools) is unique to each individua... Read More
Seen here via immunohistochemical staining of a gastric biopsy is the Heliobacter Pylori bacteria, or H. Pylori if you're in a hurry.
Able to survive the intensely acidic environment that is the human stomach, H. Pylori actually gets downright comfortable there. The bacterium has flagella and... Read More
If I take a piece of pizza that's been sitting on the table awhile and microwave it for one minute, would that kill bacteria and decrease the chance of food poisoning? -- David Chattin-McNichols
First, can bacteria really just land on your food while it's sitting on the table? Second, what's... Read More
Sewage that overflows into urban creeks and streams during periods of heavy rain can promote the spread of West Nile virus, a study led by Emory University finds.
The analysis of six years of data showed that people living near creeks with sewage overflows in lower-income neighborhoods of Sou... Read More
Some bacteria have adapted to super cold environments for millions of years. And scientists have isolated some of the essential genes that allow bacteria to tolerate their harsh living conditions—because these same genes might help in the creation of new vaccines. The investigators published the... Read More
