Scientists are reporting "laboratory resurrections" of several 2-3-billion-year-old proteins that are ancient ancestors of the enzymes that enable today's antibiotic-resistant bacteria to shrug off huge doses of penicillins, cephalosporins and other modern drugs.

Numerous food scares have made global headlines in recent years, which instigated a study in which a professor from the University of Missouri developed a technique that may make food contamination testing more rapid and accurate. This could open so many doors by promoting public health!

Global diarrhoea deaths in children aged 5 years may be attributable to rotavirus infection, and studies prove that vaccinations can help if implemented correctly. Supplemental information for Rotavirus presentation.

Data proved that a rotavirus vaccine was effective in young children in families with a middle/low income setting in El Salvador. Supplementary paper for Rotavirus presentation.

Data shows that after the implementation of routine rotavirus vaccination for infants in the United States, rotavirus cases declined substantially in the 2007-2008 season. Supplemental information for Rotavirus presentation.

This study shows that the children with rotavirus gastroenteritis, rather than bacterial gastroenteritis, had more severe cases of the disease. This implies the need for rotavirus vaccinations. Supplemental paper for Rotavirus presentation.

Bernhard Kaltenboeck, Editor Abstract Debilitating infectious diseases caused by Chlamydia are major contributors to the decline of Australia's iconic native marsupial species, the koala ( Phascolarctos cinereus). An understanding of koala chlamydial disease pathogenesis and the development of effective strategies to control infections continue to be hindered by an almost complete lack of species-specific immunological reagents.

A new study analyses the impact of animal brucellosis and bovine tuberculosis (BTB) on animals and people in urban, peri-urban and rural Niger. The World Health Organization (WHO) ranks them as major zoonoses, infectious diseases transmitted between species.

Worried about mutating to be able to pass from person to person

Scientists have discovered that the removal of the protein calpain can prevent the spread of infectious bacteria that have acquired immunity to antibiotics. Bacteria such as Listeria use the protein for growth and movement to different cellular compartments. The removal of calpain prevents bacterial movement which in turn inhibits growth.

Mediators of Inflammation is a peer-reviewed, open access journal that publishes original research and review articles on all types of inflammatory mediators, including cytokines, histamine, bradykinin, prostaglandins, leukotrienes, PAF, biological response modifiers and the family of cell adhesion-promoting molecules.

Bioterrorism is something we need to be more aware of in this day in age. The knowledge about the potential affects these agents have needs to be made more public in order for protection against them.
