First high-throughput analysis of every Salmonella Typhi gene For the first time, researchers are able to look at the need for every gene in a bacterial cell in a single experiment. The new method will transform the study of gene activity and the search for weaknesses in bacterial armories. Using a newly developed, next-gen sequencing method, a team established which genes Salmonella Typhi needs to survive and which are more of a luxury. The results and the method will be a boon to scientists...

A research group from the Rovira i Virgili University (URV) in Tarragona has developed a biosensor that can immediately detect very low levels of Salmonella typhi, the bacteria that causes typhoid fever. The technique uses carbon nanotubes and synthetic DNA fragments that activate an electric signal when they link up with the pathogen. "We have developed a new biosensor that can detect extremely low concentrations of bacteria immediately, easily and reliably", F. Xavier Rius, lead author of...

Bacterial diseases are usually detected by first enriching samples, then separating, identifying, and counting the bacteria. This type of procedure usually takes at least two days after arrival of the sample in the laboratory. Tests that work faster, in the field, and without complex sample preparation, whilst being precise and error-free, are thus high on the wish list. A Spanish research team headed by Jordi Riu and F. Xavier Rius at the University Rovira i Virgili in Tarragona has now...

A single crafty protein allows the deadly bacterium Salmonella enterica to both invade cells lining the intestine and hijack cellular functions to avoid destruction, Yale researchers report in the April 17 issue of the journal Cell. This evolutionary slight-of-hand sheds new insights into the lethal tricks of Salmonella, which kills more than 2 million people a year. "In evolutionary terms, this hijacking of cellular machinery to diversify the function of a bacterial protein is mind...

LONDON (Reuters) - Modern DNA analysis of ancient dental pulp suggests that typhoid fever was the cause of the plague which helped end the Golden Age in Athens, scientists said on Monday. The DNA collected from teeth from an ancient Greek burial site is similar to a modern organism that causes typhoid fever, an infection spread by contaminated food or water. "Studying the historical aspects of infectious disease can be a powerful tool for several disciplines to learn from," said Dr...

Salmonella enterica is a subspecies of Salmonella enterica, the rod shaped, flagellated, aerobic, Gram-negative bacterium. It is a member of the genus Salmonella and many of the pathogenic serovars of the S. enterica species are in this subspecies. Serovars can be designated fully or in a shortened form. The genus, Salmonella, is on the short form lists which are followed by the capitalized and non-italicized serovar. Each serovar can have many strains as well, which allows for a rapid...
