Arthropod vectors are responsible for the transmission of some of the most devastating diseases throughout the world. The accurate diagnosis of these diseases can be complicated due to similar clinical presentations, cross-reactivity, or the possibility of co-infection. Thus, there is a need for rapid and accurate methods of detection that can reliably distinguish between causative agents. With the recent outbreak of Zika virus throughout the Americas, it has become imperative to accurately discriminate between this virus and other similar mosquito-borne viruses. Here, we will discuss the impact of vector-borne disease and the caveats of current Zika virus detection methods.

Long-term subculturing of a microbial strain poses both a risk for cross-contamination and places selective pressure on the strain’s traits, which may lead to detrimental effects such as genetic drift and phenotypic variation. Here, we will discuss the importance of standards in microbial research and assay development.

How to minimize oxygen toxicity when propagating anaerobes

By Nancy KruegerAllison Faust

Oxygen can be quite harmful and even toxic to all cells, resulting in the oxidation of membrane lipids, inactivation of enzymes, or genetic damage. Here, we discuss several defenses that bacteria have acquired to protect themselves from oxygen toxicity.

Choosing the best media for your anaerobe

By Allison FaustNancy Krueger

Understanding your anaerobe’s nutritional requirements is essential for selecting the correct media. Presently, there are a number of broth and agar media that can be freshly prepared or purchased from commercial suppliers to support the growth of your cultures. Here, we will provide an overview of these types of media as well as the importance of using indicators and reducing agents.

Propagation methods for anaerobes

By Allison FaustNancy Krueger

For anaerobic cultures, the exclusion of oxygen from the environment is essential for growth. Presently, there are a number of methods that can be used to ensure an oxygen-free environment. Here, we will discuss several common methods for the cultivation of anaerobic bacteria.
