...April, the Microbial Science Initiative was finally announced publicly after two years of planning, initiating what will be a massive collaboration of five departments—biology, chemistry, physics, mathematics and earth and planetary sciences—to research bacteria at a microscopic level...
According the U.S. Center for Disease Control (CDC), Salmonella bacteria usually resides within human and animal intestines and are transmitted by eating foods contaminated with feces or by the unwashed hands of infected food handlers. Contaminated foods look and smell normal, making identification difficult. The illness usually lasts only four to seven days, and most people recover without treatment, according...
...years ago, and things stayed that way until what some anthropologists have called humanity's worst mistake: the invention of agriculture. We now had a steady source of food, but there were downsides as well. For one thing, our ancestors began gathering in much larger population centers, where bacteria and viruses could fester. Small bands of hunter-gatherers can spread disease only so far, but the birth of cities made epidemics possible for the first time...
...University of Illinois at Chicago scientists found that children who suffered three or more ear infections in their lifetime were twice as likely as children with no ear problems to have asthma. It's not clear what the two diseases have in common, but one possibility is that the bacteria that cause ear infections may play a role in the development of asthma. It could also be that the antibiotics used to clear up ear infections somehow increase a child's asthma risk. The study showed that children's ear-infection rates go up as their parents' education level increases...
...sore throat is one of the most common reasons for seeing a doctor. Most of the time the cause is viral, and you can ease your suffering with chicken soup and a painkiller like acetaminophen. But sometimes the problem is a kind of bacteria called group A streptococcus--or strep, for short. That's when antibiotics like penicillin or erythromycin come in handy. Early spring is a peak season for strep throat. If you have a sore throat that is accompanied by a fever but not a cough, your lymph nodes are swollen and there are yellow or white patches...
