Microbiology

Bacterial studies based on growth curves are common in microbiology and related fields. Compared to the standard photometer and cuvette based protocols, bacterial growth curve measurements with microplate readers provide better temporal resolution, higher efficiency, and are less laborious, while analysis and interpretation of the microplate-based

Control of malaria caused by Plasmodium vivax can be improved by the discovery and development of novel drugs against the parasite’s liver stage, which includes relapse-causing hypnozoites. Several recent reports describe breakthroughs in the culture of the P. vivax liver stage in 384-well microtiter plates, with the goal of enabling a

Antimicrobial-resistant Mycobacterium tuberculosis (Mtb) causes over 200,000 deaths globally each year. Current assays of antimicrobial resistance require knowledge of the mutations that confer drug resistance or long periods of culture time to test growth under drug pressure. We present ODELAM (One-cell Doubling Evaluation of Living Arrays of

Lysogenic phages can integrate into their bacterial host’s genome, potentially transferring any genetic information they possess including virulence or resistance genes, and are therefore routinely excluded from therapeutic applications. Lysogenic behavior is typically seen in phages that create turbid plaques or possess subpar bactericidal

Antibacterial coatings have currently gained great importance in biomedical technology investigations. Because of the spatial arrangement of the film coatings, evaluation of antibacterial activity presents a new challenge regarding traditional bacterial counting methods. In this protocol, four clinically relevant pathogens, Salmonella typhimurium,

Bdellovibrio bacteriovorus, an obligate predatory bacterium [i.e., bacteria that kill and feed on other bacteria (prey)], has the potential to be used as a probiotic for the disinfection of surfaces or for the treatment of bacterial infections. One option is to use this organism in combination with antimicrobials to potentiate the effectiveness of

This protocol details the construction of a simple, low-cost, small-scale, multiplex chemostat system designed for the continuous cultivation of microorganisms in suspension (i.e., bacteria, yeast, microalgae). The continuous culture device can operate at a working volume of 25 ml and allows the run of 8 chemostats in parallel by a single person.
