Researchers at Iowa State University have identified an enzyme that helps make tuberculosis resistant to a human's natural defense system. Researchers have also found a method to possibly neutralize that enzyme, which may someday lead to a cure for tuberculosis. Tuberculosis is caused by Mycobacterium tuberculosis and is a contagious disease that is on the rise, killing 1.5 to 2 million people worldwide annually. Reuben Peters, associate professor in the department of biochemistry, biophysics...

The U.S. National Institute of Allergy and Infectious Diseases says incidents of non-tuberculosis mycobacteria lung disease are increasing across the nation. Researchers said non-tuberculous mycobacteria are environmental organisms found in both water and soil that can cause severe pulmonary disease in humans -- and a large study indicates the disease is increasing. A research team led by epidemiologists from the National Institute of Allergy and Infectious Diseases, part of the National...

Nontuberculous mycobacteria (NTM) are environmental organisms found in both water and soil that can cause severe pulmonary (lung) disease in humans. Pulmonary NTM is on the rise in the United States, according to a large study of people hospitalized with the condition. A research team led by epidemiologists from the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, analyzed hospital discharge records of patients in 11 states whose combined total...

Shower heads are a perfect environment for a dangerous bacteria related to tuberculosis, University of Colorado researchers said. Mycobacterium avium thrives in wet, dark environments and can invade the lungs when sprayed from a shower head, the researchers said in a release Tuesday. While healthy people are not at risk, the microbes can be dangerous for pregnant women and people with weakened immune systems, the researchers said in this month's Proceedings of the National Academy of...

A disturbing new study has found that the showers people enjoy everyday are actually spraying them with bacteria. This news should not necessarily strike fear in those with normal immune systems, but such microbes could be a problem for those suffering from cystic fibrosis or AIDS, people who are undergoing cancer treatment or those who have had a recent organ transplant. Researchers at the University of Colorado tested 45 showers in five different states as part of a larger study of the...

A new study lays the groundwork for development of a cost-effective tool for studying the population structure and spread of Mycobacterium ulcerans, the causative agent of Buruli ulcer. Researchers at the Swiss Tropical Institute, Basel, Switzerland, and the Noguchi Memorial Institute for Medical Research, Legon, Ghana, developed SNP typing assays to systematically profile genetic diversity among M. ulcerans isolates by sequencing and comparing the genomes of selected strains. The findings,...

A British government scientist is believed to have contracted bovine tuberculosis from an infected badger, a government official said. Thirty other staff members employed by the government's Food and Environment Research Agency in Woodchester, England, near Stroud, are also being tested for the often deadly infectious disease, said Alison Wilson, FERA's head of executive support. This is the first time a suspected case of mycobacterium bovis has jumped the species barrier and caused human...

Mycobacterium tuberculosis is arguably the world's most successful infectious agent because it knows how to avoid elimination by slowing its own growth to a crawl. Now, a report in the July 10 issue of the journal Cell, a Cell Press publication, offers new insight into the bugs' talent for meager living."Tuberculosis can resist the host immune system and remain latent for decades," said Michael Glickman of the Memorial Sloan-Kettering Cancer Center. To do so, the mycobacterium responsible...

An innovative study at the Research Institute of the MUHC has brought us closer to an explanation for Crohn's diseaseTwenty-five per cent of Crohn's disease patients have a mutation in what is called the NOD2 gene, but it is not precisely known how this mutation influences the disease. The latest study by Dr. Marcel Behr, of the Research Institute of the MUHC and McGill University, has provided new insight into how this might occur. The study will be published on July 9th in the Journal of...

Researchers claim to have discovered the earliest evidence of leprosy in a 4,000-year-old skeleton from India. Gwen Robbins, an anthropologist at Appalachian State University, and a team of archaeologists from Deccan College in Pune, India, found the skeleton at the site of Balathal in Rajasthan. The region was thriving from about 3700 to 1800 B.C., they reported in the peer-reviewed journal PLoS One. Robbins' team reported that the skeleton shows evidence of erosion caused by leprosy. It...

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...

  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
