Long-Term Antibiotic Use Affects "Good" Gut Bacteria
sea-maid submitted, created time 1 month 2 weeks (health.yahoo.com)
Antibiotic treatment, especially when prolonged or repeated, may have a negative impact on beneficial bacteria that live in the gut, according to a new study.
Gut bacteria play helpful roles in various aspects of human nutrition, metabolism and immune responses, experts note.
Researchers focused on the widely-used antibiotic ciprofloxacin, prescribed for a number of bacteria-caused conditions, including urinary tract infections. It has been believed that ciprofloxacin causes only modest harm to beneficial bacteria in the body.
In this study, Stanford University's Dr 
Worlds within worlds: evolution of the vertebrate gut microbiota
sea-maid submitted, created time 3 months 2 weeks (www.nature.com)
This article is a writeup of an analysis of published 16S ribosomal RNA gene sequences to compare the bacterial assemblages that are associated with humans and other mammals, metazoa and free-living microbial communities that span a range of environments. The composition of the vertebrate gut microbiota is influenced by diet, host morphology and phylogeny, and in this respect the human gut bacterial community is typical of an omnivorous primate. However, the vertebrate gut microbiota is different from free-living communities that are not associated with animal body habitats
Metabolism indeed varies between populations

High concentrations of microorganisms are present in fermented food but their physicochemical impact on food matrices is usually neglected. In this paper and related studies ( Ly et al, Interactions between bacterial surfaces and milk proteins, impact on food emulsions stability Food Hydrocoll doi:10.1016/j.foodhyd.2007.03
Obesity Is Bacteria's Little Helper

Fat mice should consider flossing. Although not the exact conclusion of a new report, the study does indicate that--at least in rodents--obesity weakens the immune system's ability to fight off bacteria that cause gum disease. The finding helps explain why obese people are more likely to develop the oral ailment and suggests that they may be more vulnerable to other bacterial infections as well.

Humans Carry More Bacterial Cells than Human Ones

It is interesting and startling that the truth is we are practically walking petri dishes, rife with bacterial colonies from our skin to the deepest recesses of our guts.All the bacteria living inside you would fill a half-gallon jug; there are 10 times more bacterial cells in your body than human cells.
One thing is for sure: our lives and even our identities are more closely linked to the microbial world than we may think. Bacteria do a lot to keep us healthy.
Symbiotic bacteria may save endangered frogs
Darkfrog submitted, created time 1 year 8 months (www.nature.com)
I'm a bit leery of introducing one species to control another -- in this case, probiotic bacteria to kill a fungus that's killing off several amphibian species -- but if the frogs are on the brink of extinction, it might be worth the risk.
What do you think? The stakes are high. Just think of the damage the bacteria could do if something goes wrong. This is a genie-out-of-the-bottle trick. Nothing's going back in.
