Investigators have now identified two new possible contributors to rising resistance to anti-malarial drugs in Southeast Asia. The contributors are a pair of enzymes that digest the malaria parasites’ main food source.

Bathroom hot air hand dryers deposited large quantities of bacteria on agar plates held beneath the nozzles for 30 seconds and grew 15 to 60 bacterial colonies each, according to a new study.

ASM has joined the Initiative for Open Citations I4OC, a collaboration between scholarly publishers, researchers, and others to promote the unrestricted availability of scholarly citation data.

To better understand how antibiotic-resistant organisms spread in hospitals, investigators at the National Institutes of Health (NIH) in Bethesda, Maryland, recently collected samples from pipes beneath the hospital's intensive care unit and from outside manholes draining hospital wastewater. They conducted whole-genome analyses on the samples to study the bacterial plasmids, or rings of DNA, that can confer resistance to antibiotics. 

What types of data can help a clinical microbiology lab improve their performance? The latest Hot Topic provides suggestions on measuring and analyzing data points to reduce the risk of error.

Phages—viruses that infect bacteria—are abundant in the bacteria that inhabit the female bladder. This is good news, because phage could be used as alternative treatment when antibiotics become resistant to pathogenic bacteria.

To characterize the genes of newly identified bacteria, microbiologists often introduce mutations within the bacteria using mobile DNA segments called transposons to study the impact of these mutations.

Written by Katherine J. Wozniak | Tn-seq allowed researchers in two recent mBio publications to screen entire bacterial genomes to identify genes involved in surviving during nutrient deprivation.

Bacteria and fungi colonize the rubber seals of dishwashers in biofilms—which are thin, slimy, hard-to-eradicate films of these microbes that adhere to surfaces. Investigators have now shown that the diversity of species in the biofilms correlates most strongly with the age of the dishwasher, its frequency of use, and the hardness of the tap water.

In January, the American Academy of Microbiology elected 96 new Fellows. Fellows of the American Academy of Microbiology, an honorific leadership group within the ASM, are elected annually through a highly selective, peer-review process, based on their records of scientific achievement and original contributions that have advanced microbiology.
