HIV drug resistance is increasing in the UK
The prevalence of transmitted HIV drug resistance in the United Kingdom is increasing, according to a study in this week's BMJ. This finding emphasises the urgent need for new approaches to encourage safer sexual behaviour. A total of 69 patients infected with HIV between June 1994 and August 2000 were evaluated for resistance within 18 months of... view more... (2001-05-02)
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)
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)
Action needed to avoid HIV drug resistance in Africa
We should stop and think about the risks of resistance, and ways of minimising them, before increasing access to antiretroviral therapy in Africa, argue researchers in this week's BMJ. view more (2004-01-29)
Widespread uncontrolled use of antibiotics to prevent anthrax will lead to resistance
Giving antibiotics to large numbers of potentially exposed individuals to prevent anthrax will lead to resistance, according to researchers from Liverpool in this week's BMJ. As such, it is essential that they are used carefully and according to national guidelines. Although generally safe, the antimicrobial drug ciprofloxacin, which has been... view more... (2001-10-31)
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)
Theory shows mechanism behind delayed development of antibiotic resistance
Inhibiting the "drug efflux pumps" in bacteria, which function as their defence mechanisms against antibiotics, can mask the effect of mutations that have led to resistance in the form of low-affinity drug binding to target molecules in the cell. view more (2009-05-06)
Heeding the WARNing from malaria's past
A global network to monitor drug resistance and guide malaria treatment and prevention policies is being launched. view more (2007-09-06)
Passenger Screening Advised To Cut Risk Of Importing Drug-Resistant Malaria To Africa
Imported resistance has rendered ineffective the two affordable malaria drugs which have been the mainstay of malaria treatment in Africa for forty years, according to experts writing today in the journal Science. Scientists from the London School of Hygiene and Tropical Medicine and colleagues from institutions in the USA, South Africa and... view more... (2004-08-16)
New Weapon for Fighting Antibiotic Drug Resistance
The most important antibiotics in general use today are the b-lactam family of products, but the medical community faces a serious problem with these antibiotics: the increasing development of drug resistance. The resistance is caused by hydrolysis of the b-lactam by a bacterial lactamase enzyme, but fortunately it can often be overcome by the use... view more... (2003-08-11)
A new approach to study flu drug resistance
Researchers have created a new approach for studying resistance to Neuraminidase Inhibitors (NI) in influenza. view more (2007-12-07)
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)
U of M researchers discover new method to combat HIV
Researchers at the University of Minnesota's Center for Drug Design have developed a new method to combat HIV/AIDS, potentially replacing the traditional cocktail drug approach. view more (2007-07-24)
Drug resistance may travel same path as quorum sensing
The cellular "pumps" associated with multi-drug resistance in bacteria may also be involved in exporting signals responsible for cell-cell communication, a process known as quorum sensing. view more (2006-02-07)
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)
Invitation to the Media - Threatening life
You are invited to a question and answer session (15:35, 9 July 2002) on what may be the greatest threat to the future health of the nation - antibiotic resistance. |
