  5. Early Antibiotic Exposure Predisposes Mice to ObesityA new study published today in Cell suggests that antibiotic exposure during a critical window of early development disrupts the bacterial landscape of the gut, home to trillions of diverse microbes, and permanently reprograms the body’s metabolism, setting up a predisposition to obesity. Moreover, the study shows that it is altered gut bacteria, rather than the antibiotics, driving the metabolic effects.The new study by NYU Langone Medical Center researchers reveals that mice given lifelong low doses of penicillin starting in the last week of pregnancy or during nursing were more susceptible to obesity and metabolic abnormalities than mice exposed to the antibiotic later in life.Read more: http://www.laboratoryequipment.com/news/2014/08/early-antibiotic-exposure-predisposes-mice-obesity

  13. Bacteria Shed Light on Why Stress, Fear Trigger Heart AttacksScientists believe they have an explanation for the axiom that stress, emotional shock or overexertion may trigger heart attacks in vulnerable people. Hormones released during these events appear to cause bacterial biofilms on arterial walls to disperse, allowing plaque deposits to rupture into the bloodstream, according to research published in published in mBio, the online open-access journal of the American Society for Microbiology."Our hypothesis fitted with the observation that heart attack and stroke often occur following an event where elevated levels of catecholamine hormones are released into the blood and tissues, such as occurs during sudden emotional shock or stress, sudden exertion or over-exertion" says David Davies of Binghamton Univ., an author on the study.Read more: http://www.laboratoryequipment.com/news/2014/06/bacteria-shed-light-why-stress-fear-trigger-heart-attacks

  17. Bacteria, Gases Can Indicate Pipe ConditionThe nation’s sewer system is a topic most people would prefer to avoid, but its aging infrastructure is wearing out, and broken pipes leaking raw sewage into streets and living rooms are forcing the issue. To better predict which pipes need to be fixed, scientists report in the ACS journal Environmental Science & Technology that certain conditions in the pipes can clue utilities in to which ones need repair — before it’s too late.Mark Hernandez and colleagues, from the Univ. of Colorado, Boulder, note that the maintenance of U.S. wastewater collection systems costs an estimated $4.5 billion every year, much of which goes toward fixing or replacing 8,000 miles of sewers. In the future, these annual costs could top $12 billion.Read more: http://www.laboratoryequipment.com/news/2014/06/bacteria-gases-can-indicate-pipe-condition

  19. Bacteria Changes Shape to Escape DetectionEvery once in a while in the U.S., bacterial meningitis seems to crop up out of nowhere, claiming a young life. Part of the disease’s danger is the ability of the bacteria to evade the body’s immune system. Now, scientists are figuring out how the pathogen hides in plain sight. Their findings, which could help defeat these bacteria and others like it, appear in the Journal of the American Chemical Society.Linda Columbus and colleagues at the Univ. of Virginia explain that the bacteria Neisseria meningitidis, one cause of meningitis, and its cousin Neisseria gonorrhoeae, which is responsible for gonorrhea, have key-like proteins that allow them to enter human cells and do their damage. Gonorrhea can be cured, though one type of the responsible bacteria has reached “superbug” status, becoming resistant to known drugs.Read more: http://www.laboratoryequipment.com/news/2014/05/bacteria-changes-shape-escape-detection

  25. Strep Bacteria Can Fight Colon CancerResearchers at Univ. of Western Ontario have shown how the bacteria primarily responsible for causing strep throat can be used to fight colon cancer. By engineering a streptococcal bacterial toxin to attach itself to tumor cells, they are forcing the immune system to recognize and attack the cancer.Kelcey Patterson, a PhD Candidate at Western and the lead author on the study, showed that the engineered bacterial toxin could significantly reduce the size of human colon cancer tumors in mice, with a drastic reduction in the instances of metastasis. By using mouse models that are stripped of their immune system, they were able to create a “humanized mouse” – one that would not only grow human colon cancer cells, but would also support a human immune system, to test the anti-cancer immunotherapy.Read more: http://www.laboratoryequipment.com/news/2014/05/strep-bacteria-can-fight-colon-cancer

    The motto “no guts, no glory” may need rewriting if Rice Univ. synthetic biologist Jeff Tabor succeeds in his quest to help the Navy create an edible probiotic bacterium that can help protect sailors and marines from obesity and depression.

    “Our goal is to engineer a new probiotic bacterium that can protect against a common large-intestine disorder that causes obesity and depression,” says Tabor, assistant professor of bioengineering at Rice and the lead investigator on a new project funded by the Office of Naval Research (ONR).

  29. Marine Bacteria Joins Fight Against Cancer

    Yale Univ. researchers have determined how a scarce molecule produced by marine bacteria can kill cancer cells, paving the way for the development of new, low-dose chemotherapies.

    The molecule, lomaiviticin A, was previously shown to be lethal to cultured human cancer cells, but the mechanism of its operation remained unsolved for well over a decade. In a series of experiments, Yale scientists Seth Herzon, Peter Glazer and colleagues show that the molecule nicks, cleaves and ultimately destroys cancer cells’ DNA, preventing replication.
