Transmission of drug-resistant HIV-1
Drug-resistant forms of HIV can be spread between individuals who have not received anti-retroviral treatment. view more (2009-03-30)
CLASSIFICATION OF DRUG-RESISTANT TUBERCULOSIS IS MISLEADING
The traditional clinical classification of types of drug-resistant tuberculosis may be misleading, and could lead to delayed diagnosis and treatment of patients with multidrug-resistant disease, according to a study in this week's issue of The Lancet. Traditionally, patients with drug-resistant tuberculosis are classified as having acquired... view more... (2000-06-28)
Salmonella survives better in stomach due to altered DNA
Since 1995 there has been a considerable increase in the number of infections with a specific type of Salmonella bacteria transmitted via food. This type, Salmonella serovar Typhimurium DT104, is resistant to at least five different antibiotics. view more (2007-01-31)
World-wide warning of highly drug-resistant tuberculosis
New forms of highly drug-resistant tuberculosis are emerging and action must be taken soon before they become widespread globally. view more (2006-09-15)
Scientists up the ante in war against "superbugs"
Scientists have discovered a weakness in tuberculosis-causing "superbugs" which could help doctors fight the emergence of multi-drug resistant tuberculosis, says Dr Jim Naismith speaking at the BA Festival of Science at the University of Glasgow today [3rd Spetember 2001]. Tuberculosis (TB) affects more than 50 million people worldwide.... view more... (2001-08-30)
Nightshades: 'overflowing' with Phytophthora resistant genes?
The potato and other related varieties of the Solanum species contain scores or perhaps even hundreds of genes that can give the plant a degree of resistance to 'potato blight', a disease caused by Phytophthora infestans. This is one of the conclusions that came to light in Vivianne Vleeshouwers' thesis, with which she recently earned her doctoral... view more... (2001-02-01)
Can cancer drugs combine forces?
Individuals with chronic myeloid leukemia (CML) are treated first with a drug known as imatinib (Gleevec), which targets the protein known to cause the cancer (BCR-ABL). view more (2007-08-17)
Stopping germs from ganging up on humans
Keeping germs from cooperating can delay the evolution of drug resistance more effectively than killing germs one by one with traditional drugs such as antibiotics, according to new research from The University of Arizona in Tucson. view more (2008-11-20)
New drug-resistant strain of salmonella identified (p 1285)
Researchers from Taiwan report the identification of a new form of drug-resistant salmonella bacterium in this week's issue of THE LANCET. Salmonella enterica serotype choleraesuis usually causes infections that require antimicrobial treatment. Multidrug-resistant strains have been identified, but the antimicrobial ceftriaxone has been effective... view more... (2004-04-14)
XDR TB in South Africa traced to lack of drug susceptibility testing
In South Africa, the 2001 implementation of the World Health Organization's anti-tuberculosis program may have inadvertently helped to create a new strain of extensively drug-resistant tuberculosis (XDR TB). view more (2007-10-23)
Treatment outcomes highlight dangers of extensively drug-resistant tuberculosis
In a retrospective study of 174 tuberculosis patients treated at National Jewish Health (formerly National Jewish Medical and Research Center), patients with extensively-drug-resistant tuberculosis (XDR-TB) were almost eight times as likely to die as patients with multi-drug resistant tuberculosis (MDR-TB). view more (2008-08-07)
Innocuous intestinal bacteria may be reservoir for resistance
"Harmless" bacteria in the digestive tracts of dairy cows, may not be so harmless after all. They may be a reservoir for antibiotic resistance genes that can be transferred to more harmful, disease-causing bacteria. view more (2006-05-25)
e-Science methods reveal new insights into antibiotic resistance
Large-scale computer simulations have pinpointed a tiny change in molecular structure that could account for drug resistance in Streptomices pneumoniae, the organism that causes childhood pneumonia and claims 3.5 million lives a year, mainly in developing countries. view more (2005-08-16)
New research may overturn conventional wisdom on drug-resistant tuberculosis
A newly released study suggests that the majority of cases of drug-resistant tuberculosis (TB) among patients undergoing treatment for the disease may be due to new infections, not acquired resistance. view more (2007-02-21)
DOTS Show the Way to Tackle the Toughest TB.
New research has shown for the first time that the spread of multi drug-resistant TB can be halted through a well executed standard treatment programme. Bacterial fingerprinting techniques used to track disease transmission in a southern Mexico community revealed that all categories of tuberculosis were controlled when the DOTS strategy was used. view more (2005-04-01)
Bacterial spread all down to chance: some strains 'just the lucky ones'
Scientists have discovered that factors such as human immunity and drug resistance are less important to the success of bacterial spread than previously thought. view more (2005-02-03)
BACTERIA DEVELOP RESISTANCE TO NEW ANTIBIOTIC (p1179)
Multi-drug resistant bacteria have caused enormous difficulties worldwide over the past few decades. Scientists had hoped, however, that new drugs currently available for prescription would help to suppress the emergence of super-bugs such as meticillin resistant Staphylococcus aureus that hit the British headlines last year. But, research... view more... (2001-04-11)
The complexities of genetic susceptibility to tuberculosis revealed
Researchers working in Vietnam have identified a genetic variant that predisposes people to developing a lethal form of tuberculosis (TB), tuberculous meningitis, if they are infected with a strain of TB known as the Beijing strain. view more (2008-03-28)
Drug resistant hospital bugs also learning to beat disinfectant, say scientists
Dangerous multi-drug-resistant bacteria are also developing immunity to hospital disinfectants and antiseptics, according to new research presented today (Wednesday, 08 September 2004) at the Society for General Microbiology's 155th Meeting at Trinity College Dublin. view more (2004-08-23)
A molecule impedes the destruction of the 'Brucella' bacteria
Research carried out with the participation of the University of Navarra has shown how a determinate molecule helps an important pathogen, Brucella abortus, escape destruction within the cells charged with eliminating infectious agents (macrophages). view more (2005-06-15)
