An outbreak of tuberculosis in the skid row area of downtown Los Angeles may have exposed up to 4,500 individuals to the bacterium that causes the deadly disease and has left federal officials scrambling to intervene. http://medicalxpress.com/news/2013-02-wolf-sheep-uncovering-deadly-bacteria.html Medical research Thu, 28 Feb 2013 14:00:04 EST news281280867 A natural product secreted by a soil bacterium shows promise as a new drug to treat tuberculosis report scientists in a new study published in EMBO Molecular Medicine. A team of scientists working in Switzerland has shown how pyridomycin, a natural antibiotic produced by the bacterium Dactylosporangium fulvum, works. This promising drug candidate is active against many of the drug-resistant types of the tuberculosis bacterium that no longer respond to treatment with the front-line drug isoniazid. http://medicalxpress.com/news/2012-09-scientists-reveal-natural-antibiotic-tuberculosis.html Diseases, Conditions, Syndromes Mon, 17 Sep 2012 09:30:13 EST news267093003 The only tuberculosis vaccine currently available is already over 90 years old - and is unsatisfactory in terms of its effectiveness. Although it protects young children against developing tuberculosis, it quickly loses its effectiveness and does not protect young people and adults against the infection. Scientists from the Max Planck Institute for Infection Biology in Berlin have now developed an improved vaccine which has been undergoing clinical trials on humans since 2008. The safety and tolerability of the vaccine candidate is being tested in a Phase II trial on infants in South Africa. The results of the preceding Phase I trial have already shown that the vaccine candidate fulfils the relevant safety requirements and that its mechanism of action works. http://medicalxpress.com/news/2012-03-tuberculosis-vaccine-phase-ii-trial.html Medications Mon, 26 Mar 2012 07:58:58 EST news251967524
