The efforts of antibiotic stewardship campaigns are starting to show positive results in the clinic. These trends can serve as motivation to all to continue education campaigns for appropriate use of antibiotics.

Can the microbiome be used for forensic purposes? The skin microbiome is fairly stable, and a new Applied and Environmental Microbiology report assesses the use of genetic markers in the skin bacterium Proprionibacterium acnes for human identification purposes. 

How do we know which cells and what species are susceptible to viral infection? One way is to look for the presence of the viral receptor, if known. Sialic acid is the host cell receptor for influenza virus attachment, and a new mSphere report describes tools to help survey the species distributions of different sialic acid modifications that will inform susceptibility.

Determining the susceptibility of HIV to antiretroviral drugs is important for getting patients the right combination of ART. A new Journal of Clinical Microbiology compares next-generation sequencing to traditional Sanger sequencing and PCR analyses to determine the most accurate method of measuring viral resistance.

Listeria biofilms resist disinfectants

Cleaning and disinfecting food prep surfaces is vital to minimize the risk of foodborne pathogen contamination. A new Applied and Environmental Microbiology article shows that well-known foodborne pathogen Listeria monocytogenes resists removal by current industrial formulations of disinfectants. 

Two-component signaling is important for many bacterial activities, including movement, growth, differentiation, and metabolism, among others. The latest Special Issue of the Journal of Bacteriology highlights recent advances in two-component signaling, including minireviews and primary research articles. 

Fungal infections, like those caused by Candida albicans, are a serious clinical problem. Systemic candidiasis can result from fungal biofilms growing on plastic indwelling devices. A new Antimicrobial Agents and Chemotherapy article reports the anti-biofilm activity of a eucalyptus-derived compound, which acts by regulating fungal cell morphology.

Foot and mouth disease remains a threat to livestock. A Journal of Virology report describes a new chimeric vaccine scheme that can mix-and-match to protect against different serotypes. The research here demonstrates a vaccine platform that may be able to help responders rapidly provide protective vaccines during disease outbreaks.

C. auris survives on plastic

The emerging multidrug-resistant fungal pathogen Candida auris has caused outbreaks in several healthcare facilities. New research from the Journal of Clinical Microbiology suggests the fungus can survive for weeks on plastic surfaces, emphasizing the importance of infection control in these facilities. 

Colistin acts by interacting with the bacterial envelope via charge interactions, a very similar mechanism to how host antimicrobial peptides (AMPs) and bacterial membranes interact. A new Antimicrobial Agents and Chemotherapy report demonstrates that clinical colistin-resistant isolates remain susceptible to AMPs.
