Notas que nadie comenta...


Comentaremos brevemente las muy destacadas notas de este par de días del sitio de noticias Science Daily. Pásele...

La nota que nos llamó la atención es "Early Exposure to Antibiotics May Impact Development, Obesity". En ella se destaca lo que ha hemos reseñado con anterioridad, que el uso de antibioticos en la industria ganadera no tiene control y provoca una exposición de alcances poco estudiados en el humano.
Pues aqui se reseña el artículo de la revista Nature, (Antibiotics in early life alter the murine colonic microbiome and adiposity. Nature, 2012; DOI: 10.1038/nature11400)

El meollo del trabajo es el siguiente:

The researchers administered STAT (SubTherapeutic Antibiotic Therapy, qué contradicción de nombre, ¿no creen?)  to normal mice and observed that the mice receiving antibiotics developed increased fat mass and percent body fat. After about six weeks, the mice that received antibiotics had gained about 10 to 15 percent more fat mass than the mice that did not receive antibiotics. The researchers also noted that bone density was significantly increased in STAT mice early in development and that particular hormones related to metabolism were affected by antibiotic exposure, as well.
"By using antibiotics, we found we can actually manipulate the population of bacteria and alter how they metabolize certain nutrients," said Dr. Cho, assistant professor of medicine and associate program director for the Division of Gastroenterology at the School of Medicine.
