Antibiotic Resistant Bacterium Uses Sonar-like Strategy to “See?Enemies or Prey

For the first time, scientists have foundthat bacteria can use a Sonar-like system to spot other cells (eithernormal body cells or other bacteria) and target them for destruction.Reported in the December 24 issue of Science, this finding explains howsome bacteria know when to produce a toxin that makes infection moresevere. It may lead to the design of new toxin inhibitors. “Blocking orinte...

Study identifies predictors of HIV drug resistance in patients beginning triple therapy

A scientist at the Marine BiologicalLaboratory (MBL) has published the results of an EPA-funded clam embryostudy that supports her hypothesis that, when combined, the pollutantsbromoform, chloroform, and tetrachloroethylene--a chemical cocktailknown as BCE--can act synergistically to alter a key regulator in nervecell development. While scientists have previously studied the effectsof these...

Enzyme allows B cells to resist death, leading to leukemia

B cell chronic lymphocytic leukemia (B-CLL)is the most common leukemia in adults and is characterized by theprogressive accumulation of mature B lymphocytes in the blood, bonemarrow, and lymphatic tissues. It is believed that in the early stagesof disease, B-CLL is the result of an undefined defect in theprogrammed signals that trigger normal B cell death (apoptosis). LivioTrentin and colle...

NYC's First Rapid HIV Drug-resistant AIDS Case Prompts Call to Step Up HIV Prevention

New York City's Public Health Department today issued a public health advisory after reporting the first documented case of an alarming, new, rapidly-progressing and highly drug resistant strain of HIV in a New York man who progressed from his initial HIV infection, thought to have occurred in mid-October 2004, to a largely untreatable strain of AIDS in just three months. According to City...

Drug-resistant bacteria on poultry products differ by brand

The presence of drug-resistant, pathogenic bacteria on uncooked poultry products varies by commercial brand and is likely related to antibiotic use in production, according to researchers at the Johns Hopkins Bloomberg School of Public Health. Their study is the first to directly compare bacterial contamination of poultry products sold in U.S. supermarkets from food producers who use antibiotics...

New antibiotic already developing resistance

An anti biotic, just a year old, which was developed to fight resistant bacteria, is already becoming stale as the bacteria are showing signs of resistance. The drug linezolid is used to treat Enterococcus faecium (E. faecium) infections that are resistant to the old standby antibiotic vancomycin. The hope has been that the new drug would help tackle the growing problem of vancomycin-res...

African HIV strains more resistant to anti HIV drugs

Genetic variations in the HIV strains in Africa make it more difficult for the anti AIDS drugs to act on them according to researchers. This however does not mean that these drugs will be powerless against the virus but these drugs find it difficult to latch on to the protease, which is an enzyme useful in the replication of the virus inside the body. If the drug attaches itself to the p...

E. coli strains resistant to a common antibiotic

Food contaminated with a strain of drug-resistant E. coli has emerged as a possible new source of urinary tract infections. E. coli is a normal inhabitant of the digestive tract that can cause both intestinal upsets and urinary infections. But while E. coli from bad food is a frequent cause of diarrhoea and other digestive miseries, urinary tract infections were thought until now to resul...

New HIV cases resist drugs

About 40,000 people are infected with HIV every year in the US, with half the cases in people under 25. More than three-quarters of all U.S. patients with the AIDS virus have an infection that resists one or more of the drugs used to treat it. // Drug-resistant HIV had spread faster and the lifesaving cocktails of drugs that help many patients lead normal lives were becoming increasingly...

Controlling the Spread of Healthcare Associated Methicillin Resistant Staphylococcus aureus Requires Active Surveillance

Both methicillin sensitive and methicillin resistant Staphylococcus aureus (MSSA, MRSA) can cause invasive and life-threatening infections such as osteomyelitis, septicemia, endocarditis, and pneumonia. Healthcare associated MRSA is of particular clinical importance because it is not only predictably cross resistant to all penicillins and cephalosporins, but is also typically resistant to mu...
