Bacteria are unicellular organisms. They can be totally harmless or even beneficial to humans, including some present in the intestine. But they are also responsible for various infections.
In recent years, we hear more and more nosocomial infections contracted by patients during their hospitalization. These infections are particularly important if the prosthetics break. Once infection is established, the patient must in fact often be reoperated. During the past 20 years, 1700 patients had to be reoperated in Norway for this reason, 200 in 2009 alone.

An international team of researchers has decoded the genome of the domestic horse Equus caballusAnd have revealed a genomic structure with striking similarities with humans and more than one million genetic differences between different breeds of horses. The work, published this week in ScienceSheds light on a key part of the mammal branch of the evolutionary tree, and provides a starting point to create a map of the genes that cause disease in horses.
 Three years ago, the international team of scientists led by researchers at the Broad Institute of MIT and Harvard (USA) started a project to decode the genetic pattern of the horse. The effort was based on international collaboration for ten years in order to exploit genomic technologies for the benefit of equine health, known as the Horse Genome Project (the Horse Genome Project).
“Horses and humans have similar diseases, so that identification of the culprits in horses promises to bring a deeper understanding of the diseases in these two bodies.

Researchers at the Consejo Superior de Investigaciones CientÃficas (CSIC), the Group of the Bearded Vulture Study and Protection and the University Miguel Hernandez de Elche (Alicante) this week published a letter in the journal Science in asserting that “leave animal carcasses in situ-taking appropriate health precautions, is the most environmentally friendly, cheap and efficient to ensure the preservation of scavengers.
 In 2001 an outbreak of bovine spongiform encephalopathy (or mad cow disease) caused the European Union (EU) ban on leaving the bodies of these birds in the field, and forced to destroy or reuse in approved premises.
The measure had a great impact on the population of vultures, stopped their growth and caused a power shortage and the increased mortality among younger specimens.

An international consortium of more than 68 scientists plan to create a “zoo of the genome, a collection of DNA sequences from 10,000 species of vertebrates, almost one for each kind of vertebrate. Is 10K Genome Project which will constitute the most comprehensive study of animal evolution ever attempted.
 10K Genome Project will collect samples of thousands of animals from zoos, museums and university collections around the world and then sequenced the genome of each species to reveal its complete genetic inheritance. The group of 68 scientists and common denominators of genome scientists 10K (G10KCOS) project began in April 2009 at a meeting at the University of California (UC), Santa Cruz (USA).

Researchers at the Center for Genomic Regulation (CRG) have described a system that achieved by reprogramming convert B cells into macrophages in 2 or 3 days. The work is magazine cover Cell Stem Cell and presents the results of the research group led by Austrian-alemanThomas Graf.
 Increasingly, research groups trying to uncover the mechanisms of cell differentiation to achieve reprogramming differentiated cells. This time, researchers have managed CRG describe a cellular reprogramming process that results in morphologically and functionally different cells with an efficiency of 100%.
Researchers have used stem cells and B cells have been reprogrammed to develop into macrophages by inducible expression of a single transcription factor. Both types of cells are part of the immune system but among them there are great differences in morphology, structural and functional.
