Pinhead-size worms + robot = new antibiotics

Scientists in Massachusetts are describing successful use of a test that enlists pinhead-sized worms in efforts to discover badly needed new antibiotics. Thestudy appears in ACS' Chemical Biology.

From the abstract:

The nematode Caenorhabditis elegans is a unique whole animal model system ... Read More

”Build a Bacterium” Scavenger Hunt

In this activity, each student is provided with a worksheet and three index cards. Each card indicates a different cell part (e.g. LPS, capsule, DNA). Students are placed in small groups and receive a written scenario regarding a bacterium with a certain goal it must carry out. They must work t... Read More

The Rise of Community-Associated MRSA

This teleconference is sponsored by the American Society for Microbiology and will review the history and importance of methicillin-resistant Staphylococcus aureus (MRSA) with a primary focus on the emergence of community-associated MRSA (CA-MRSA). The phenotypic and molecular identification of ... Read More

Colony Collapse Disorder: A Descriptive Study

A recent study published earlier this week from Washington State University suggests Nosema ceranae, a unicellular parasite, and pesticides embedded in old honeycombs are two major contributors to the bee disease known as colony collapse disorder. Now, the first descriptive epizootiological surv... Read More

Staph's Virulence and Resistance Genes Can Transfer in Pairs

Scientists studying Staphylococcus bacteria, including methicillin-resistant S. aureus (MRSA), have discovered a potent staph toxin responsible for disease severity. They also found the gene for the toxin traveling with a genetic component of Staphylococcus that controls resistance to antibiotic... Read More

Sign Up for the Scrub Club

The Scrub Club created by NSF International is designed for children who are 3 to 8 years of age. The web site is a fun, interactive and educational resource that teaches children about the microbes that make them sick and the proper way to wash their hands. The site is a hodgepodge of fun flash... Read More

Communication breakdown: A new way to overcome antibiotic resistance

Interfering with communication among bacteria can prevent them from mounting a unified and perhaps deadly assault on their host organism, research by Howard Hughes Medical Institute (HHMI) investigators shows. The finding suggests a different kind of medicine that could be less likely than tradi... Read More
