New research published in the Journal of Leukocyte Biology suggests that lack of expression of innate immune system receptor may play a critical role in the immune response to mycobacterial infections Are you genetically predisposed to tuberculosis? Scientists may now be able to answer this question and doctors may be able to adjust their therapeutic approach based on what they learn. That's because new research presented in the Journal of Leukocyte Biology (http://www.jleukbio.org) suggests...

Leprosy cases reported in the US only number around 150 per year and the majority of these cases can be attributed to travel to places such as Angola, Brazil and India. However, Scientists have identified a source for some of the unexplained cases that appear in the southern US - the nine-banded armadillo. DNA samples were taken from 33 wild armadillos in Arkansas, Alabama, Louisiana, Mississippi and Texas. Armadillos are one of the very few mammals that can carry the bacteria causing the...

(Ivanhoe Newswire) -- A new study published in the New England Journal of Medicine reveals a new strain of leprosy has surfaced in the Southern United States. Leprosy is a chronic, mildly contagious disease of tropical and subtropical regions with a long and extensive history. Until the 20th century, infected people were ostracized from society or at best segregated and cared for in isolated leper colonies. Today, the disease is entirely curable through multidrug therapy, though tissue damage...

The discovery of two genes that encode copper- and sulfur-binding repressors in the hospital terror Staphylococcus aureus means two new potential avenues for controlling the increasingly drug-resistant bacterium, scientists say in the April 15, 2011 issue of the Journal of Biological Chemistry. "We need to come up with new targets for antibacterial agents," said Indiana University Bloomington biochemist David Giedroc, who led the project. "Staph is becoming more and more multi-drug resistant,...

The Centers for Disease Control and Prevention (CDC) fell short of its goal of eradicating tuberculosis (TB) by the year 2010, health officials told AFP recently, despite the number of reported cases being at an all-time low. The CDC publication Morbidity and Mortality Weekly Report, found 11,181 known cases of the airborne and highly contagious disease in the US last year, a 3.9 percent drop from 2009. Tuberculosis is caused by the mycobacterium tuberculosis bacterium and usually attacks...

RICHMOND, Va., March 21, 2011 /PRNewswire/ -- Insmed Incorporated (Nasdaq: INSMD), a biopharmaceutical company, announced today that the Company's Investigational New Drug Application (IND) to conduct a pivotal Phase 3 clinical trial of ARIKACE(TM) (liposomal amikacin for inhalation) in nontuberculous mycobacteria (NTM) lung infections has been cleared by the U.S. Food and Drug Administration (FDA). In 2010, Insmed initially submitted a regulatory filing to FDA requesting clearance to...

Nele Festjens and Nico Callewaert of VIB and Ghent University have improved the efficacy of the vaccine for tuberculosis. The new vaccine affords - as already proven in mice - better protection against the disease. The development of a new tuberculosis vaccine is a priority in the fight against the disease which claims the lives of 1.7 million people each year. The current vaccine provides only partial protection. Nico Callewaert: "Our vaccine is more effective because it is more quickly...

The realization of medically treating different children uniquely may start with one of the deadliest diseases in existence: tuberculosis. New findings by UT Southwestern Medical Center researchers indicate that the type of medications and the dosage routinely used to treat children with the disease should be individualized to each young patient in order to be effective. The findings, available online and in the February issue of Antimicrobial Agents and Chemotherapy, show that currently...

New research published in the Journal of Leukocyte Biology suggests that the effectiveness of the bacille Calmette-Guerin vaccine is compromised by environmental bacteria A new discovery may explain why a tuberculosis vaccine is not as effective for some people as anticipated, and potentially explains why other vaccines do not work as well for some as they do for others. In a research report presented in the December 2010 issue of the Journal of Leukocyte Biology (http://www.jleukbio.org),...

A team of researchers from Spain and Latin America have synthesized two iron compounds that inhibit the in vitro growth of Mycobacterium tuberculosis, the bacteria that causes tuberculosis. Due their low level of toxicity in mammel cells, the compounds could be used in the future as therapeutic agents and hospital disinfectants. A group of researchers from the Universidad de Navarra (Spain), the Universidad de la República (Uruguay), the Universidad de...

Mycobacterium tuberculosis (MTB) is a pathogenic bacterial species in the genus Mycobacterium and the causative agent of most cases of tuberculosis. Robert Koch first discovered it in 1882 and that it had an unusual, waxy coating on the cell surface which makes them impossible to Gram stain. M. tuberculosis is highly aerobic and requires high levels of oxygen. It generally infects the respiratory system of mammals. Tuberculin skin test, acid-fast stain, and chest radiographs are the most...

Mycobacterium bovis is a slow-growing, aerobic bacterium and the causative agent of tuberculosis in cattle. Similar to M. tuberculosis, M. bovis can jump the species barrier and cause tuberculosis in humans. It is estimated that M. bovis was responsible for more losses among farm animals than all other diseases combined in the first half of the 20th century. Infection happens after bacterium is ingested. It is generally transmitted to humans via infected milk. Actual human infections are...
