Researchers Discover Key Mechanism To Emergence Of Deadly Strep Bacteria. The incidence of serious strep infections has risen dramatically in the last three decades, and this increase is largely attributed to the spread around the globe of a single strain of strep known as the invasive M1T1 clone.
Researchers at the University of California, San Diego (UCSD) School of Medicine and the University of Wollongong in Australia have discovered that, 30 years ago, a virus infected the strep bacteria – creating a deadly strain of “flesh-eating” bacteria that has evolved to produce serious human infections worldwide. Bloodstream infections correlate with distance from the equator and health care spending. Twenty-three health centers on six continents participated in study of bloodstream infections Where you live affects the type of bacteria that cause bloodstream infections, according to researchers at Rhode Island Hospital and an international team of investigators.
The closer you live to the equator, the greater the likelihood of a bloodstream infection caused by a group of bacteria called Gram-negative bacteria, which thrive in warm and moist environments, compared to another group of bacteria referred to as Gram-positive bacteria. The study also found that the proportion of a country's GDP spent on health care impacted the type of bacteria causing such infections. The study was published in the scientific journal PLOS ONE. "It's fascinating to discover how geography and socioeconomic determinants factor into disease management," said Mermel.
One more question, Dr. Frieden: Thirteen things we'd like CDC to tell us about first U.S. Ebola diagnosis. By 11 Comments At a press conference Tuesday afternoon, Tom Frieden, the director of the U.S.
Centers for Disease Control and Prevention (CDC), announced the first case of Ebola from the current epidemic that was diagnosed outside of Africa. The patient arrived in Dallas, Texas, on 20 September to visit relatives. Until today, the handful of people with Ebola in the United States were all diagnosed in Africa, carefully transported, and immediately provided with care in isolation units at hospitals. The new patient had his temperature taken before boarding the flight out of Liberia on 19 September, U.S. officials say, and had no disease symptoms at the time. Two ScienceInsider reporters called in to the press conference, but there was so much interest from the media that they did not get a chance to ask a question.
Q: Dr. Healthy humans 'harbor an average of five viruses' Strains of HPV were found in around 75% of participants' skin samples and 50% of nose samples, while new strains of the virus were found in both skin and nose samples.
"Most everyone is familiar with the idea that a normal bacterial flora exists in the body," says study co-author Dr. Gregory Storch, a virologist and chief of the Division of Pediatric Infectious Diseases at the university. "Lots of people have asked whether there is a viral counterpart, and we haven't had a clear answer. But now we know there is a normal viral flora, and it's rich and complex. " The findings, which form a part of the Human Microbiome Project funded by the National Institutes of Health, were recently published in the journal BMC Biology.

The evolution of a diarrhoeal viral genome. Post by Rebecca Gladstone, University of Southampton Two billion cases of severe diarrhoea occur globally each year, representing the second leading cause of death in children under five years old, according to the World Health Organization.
Diarrhoeal disease is both preventable and treatable. Devastating epidemics, outbreaks and sporadic cases of severe diarrhoea can be caused by the group B rotaviruses (RVBs). Using genomic sequencing, researchers have uncovered the evolutionary origins and diversity of human RVBs which will allow better diagnostic and disease prevention strategies to be developed. The results were recently published in Journal of General Virology. RVBs can infect humans and a range of other mammalian and avian species which impacts negatively on the economy through human morbidity and agricultural losses.
El virus del Nilo se hace global. El concepto de enfermedad tropical (más bien ecuatorial) está en entredicho.
La combinación entre calentamiento global y viajes intercontinentales ha facilitado que patógenos exclusivos de zonas cálidas y remotas se hayan asentado en otras latitudes. El caso de mayor éxito es el virus del Nilo Occidental, un microorganismo que se detectó por primera vez en 1937 en Uganda, cerca de una de las fuentes del gran río africano, y que ha colonizado ya EE UU, donde ha causado 1.590 infecciones en humanos y 66 muertos este año. La situación es tan peligrosa que ayer se inició la fumigación de Nueva York, a 4.500 kilómetros del ecuador. Virus emergentes y cambio global.

Human papillomavirus (HPV) vaccination was introduced into the routine immunization schedule in the United States in late 2006 for females aged 11 or 12 years, with catch-up vaccination recommended for those aged 13–26 years. In 2010, 3-dose vaccine coverage was only 32% among 13–17 year-olds. Methods. Results. Conclusions. Received February 14, 2013.
