The protective milk shot – How mother’s milk protects piglets from parasite infections

Coccidiosis is a serious disease in new-born piglets. Caused by the parasite Cystoisospora suis, it exclusively infects pigs and often causes severe diarrhoea in suckling piglets. Parasitologists at the Vetmeduni Vienna have developed a new strategy for protecting the piglets: They infected sows... Read More

How the Body’s Cells Hold on Tight

When I was nine, biology gave me my first existential crisis. If I am built out of trillions of tiny cells, I worried, what’s to keep me from crumbling into a pile like a dried-out sandcastle? Almost two decades later, as a Ph.D. student in mathematics at the University of California, Davis, I’m... Read More

Gonorrhea Infections Start From Exposure To Seminal Fluid

Researchers have come a step closer to understanding how gonorrhea infections are transmitted. When Neisseria gonorrhoeae, the bacteria responsible for gonorrhea, are exposed to seminal plasma, the liquid part of semen containing secretions from the male genital tract, they can more easily move ...

New drugs for bad bugs

Washington University in St Louis chemist Timothy Wencewicz says we’ll stay ahead of antibiotic resistance only if we find drugs with new scaffolds, or core chemical structures. One promising candidate, an antibiotic made by a bacterium than infects plants, caught his attention because it contai... Read More

Battling Infection With Microbes

The human relationship with microbial life is complicated. At almost any supermarket, you can pick up both antibacterial soap and probiotic yogurt during the same shopping trip. Although there are types of bacteria that can make us sick, Caltech professor of biology and biological engineering Sa... Read More

Resurrecting ancient microbes to understand evolution

When you hear the word “resurrection”, what’s the first thing that comes to mind? Religious miracles? Zombie viruses? The end of the world?

Whatever your mental association, I’m willing to bet it’s not “an emerging scientific discipline." Well, it just so happens a growing community of microb... Read More

The Science Behind Honey’s Eternal Shelf Life

Modern archeologists, excavating ancient Egyptian tombs, have often found something unexpected amongst the tombs’ artifacts: pots of honey, thousands of years old, and yet still preserved. Through millennia, the archeologists discover, the food remains unspoiled, an unmistakable testament to the... Read More

A WORD on the constraints of influenza virus evolution

Evolution proceeds by selection of mutants that arise by error-prone duplication of nucleic acid genomes. It is believed that mutations that are selected in a gene are dependent on those that have preceded them, an effect known as epistasis. Analysis of a sequence of changes in the influenza vir...

2,300 tubes containing SARS virus samples missing in France

A major French biomedical research body, the Pasteur Institute, have launched an investigation into the disappearance of some 2,300 test tubes containing samples of the SARS virus. The loss was discovered during an inventory.

The Pasteur Institute filed a so-called 'complaint against X' on Mo... Read More

New research shows that bacteria survive longer in contact lens cleaning solution than previously thought

Each year in the UK, bacterial infections cause around 6,000 cases of a severe eye condition known as microbial keratitis - an inflammation and ulceration of the cornea that can lead to loss of vision. The use of contact lenses has been identified as a particular risk factor for microbial kerati... Read More

New Research on Antibiotic-Resistant Bacteria, Pressure Ulcers, Severe Alcoholic Hepatitis, and More

Two million people suffer antibiotic-resistant infections yearly, and 23,000 die each year as a result. Most of these infections occur in the community, but deaths usually occur in healthcare settings. Cost estimates vary but may be as high as $20 billion in excess direct healthcare costs.

Why Do Bacteria Thrive in Space?

For reasons that still aren't well understood, bacteria proliferate in microgravity. Creating a potential recipe for disaster for humans stationed in space for long periods, bacteria's love of low-g also raises an intriguing question: Why are they so comfortable there?

Environment influences ability of bacterium to block malaria transmission

The environment significantly influences whether or not a certain bacterium will block mosquitoes from transmitting malaria, according to researchers at Penn State.

The researchers used a species of malaria parasite that affects rodents, Plasmodium yoelii, and the mosquito, Anopheles stephens... Read More

Bacteria 'could be a cause of preterm births'

New research from the US has found a link between preterm births where the water sac around the baby breaks prematurely, and bacteria near where the walls of the sac are thinner.

The researchers, including Amy P. Murtha, associate professor of obstetrics and gynecology at Duke University Scho... Read More

Tube morphology

Three organisms inoculated in TSB to look at tube morphology. From left to right:
Staphylococcus aureus: flocculent growth/turbid, growth throughout the tube.
Mycobacterium smegmatis: pellicle, growth at the top of the tube. M. smegmatis tends to stick to the tube and grow up the side.
Ba... Read More
