Studies highlight MRSA evolution and resilience

A single strain of an evolving bacterium has been responsible for most of the community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections. – Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) infections are caused primarily by a single strain-USA300-of an evolving bacterium that has spread with “extraordinary transmissibility” throughout the United States during the past five years, according to a new study led by National Institutes of Health (NIH) scientists. CA-MRSA, an emerging public health concern, typically causes readily treatable soft-tissue infections such as boils, but also can lead to life-threatening conditions that are difficult to treat.

Chromosomal abnormalities play substantial role in autism

Chromosomal abnormalities play substantial role in autism, revealed in a study. Noting this change would help early diagnosis for autism or autism spectrum disorder (ASD) – a kind of developmental disorder. – Genome-wide scans of families affected by autism spectrum disorder (ASD) have revealed new evidence that previously unknown chromosomal abnormalities have a substantial role in the prevalent developmental disorder, according to a report published online Jan. 17th in the American Journal of Human Genetics, a publication of Cell Press.
