+i An anonymous reader quotes a report from The Guardian: The gut\r
+i microbiome is the sum total of all the micro-organisms living\r
+i in a person's gut, and has been shown to play a huge role in\r
+i human health. New research has found probiotics -- usually\r
+i taken as supplements or in foods such as yoghurt, kimchi or\r
+i kefir -- can hinder a patient's gut microbiome from returning\r
+i to normal after a course of antibiotics, and that different\r
+i people respond to probiotics in dramatically different ways.\r
+i In the first of two papers published in the journal Cell,\r
+i researchers performed endoscopies and colonoscopies to sample\r
+i and study the gut microbiomes of people who took antibiotics\r
+i before and after probiotic consumption. Another group were\r
+i given samples of their own gut microbiomes collected before\r
+i consuming antibiotics. The researchers found the microbiomes\r
+i of those who had taken the probiotics had suffered a "very\r
+i severe disturbance." "Once the probiotics had colonized the\r
+i gut, they completely inhibited the return of the indigenous\r
+i microbiome which was disrupted during antibiotic treatment,"\r
+i said Eran Elinav, an immunologist at the Weizmann Institute of\r
+i Science in Israel and lead author on the studies. The\r
+i scientists also compared the gut microbiomes of the gut\r
+i intestinal tract of 25 volunteers with that of their stools.\r
+i They found that stool bacteria only partially correlated with\r
+i the microbiomes functioning inside their bodies. "So the fact\r
+i that we all almost exclusively rely on stool in our microbiome\r
+i research may not be a reliable way of studying gut microbiome\r
+i health," said Elinav. In the second paper, the researchers\r
+i examined the colonization and impact of probiotics on 15\r
+i people by sampling within their gastrointestinal tract. They\r
+i divided the individuals into two groups: one were given a\r
+i preparation made of 11 strains of very commonly used\r
+i probiotics and the other were given a placebo. Of those who\r
+i were given probiotics, he said, "We could group the\r
+i individuals into two distinct groups: one which resisted the\r
+i colonisation of the probiotics, and one in which the\r
+i probiotics colonized the gut and modified the composition of\r
+i the gut microbiome and the genes of the host individual."\r
