Article Abstract
Quantitative PCR (qPCR) is a well-established technique that allows to accurately quantify nucleic acids or proteins, being widely used in several types of biological samples for bacterial load quantification. However, there are many recent studies that do not consider the potential pitfalls involved in key experimental qPCR stages, namely, those related to the extraction and purification of genomic DNA and to the thermal amplification process, that can lead to biased results in mixed cultures. Herein, we outline a proper protocol for bacterial quantification by qPCR, addressing how to overcome the main issues in that methodology.

Microbial consortia, involving two or more microorganisms, have been explored for pest management purposes, despite concerns regarding competitive exclusion among entomopathogenic fungi that may undermine synergistic effects. However, the precise molecular mechanisms governing entomopathogen competition in vivo remain inadequately elucidated. Here, we investigate competitive exclusion dynamics between two prominent entomopathogens, Metarhizium robertsii and Beauveria bassiana.

Foodborne diseases are caused by various pathogens and generally present with similar symptoms, mainly digestive disorders. Adopting a syndromic approach is therefore important when investigating foodborne disease outbreaks. This involves using multiplex PCR-based methods to test stool and food samples.

This study investigated the effects of five representative biocarriers-biochar (BC), activated carbon (AC), nano-magnetite (NM), zero-valent iron (ZVI), and polyurethane sponge (PUS)-on chain elongation (CE) from ethanol/acetate in anaerobic systems. All carriers enhanced CE to varying extents. BC and NM significantly increased caproate yields (6032.

Malaria, a protozoan parasitic disease caused by Plasmodium species, poses significant health risks in endemic regions and contributes to substantial morbidity and mortality. The intricate lifecycle of the parasite, coupled with the emergence of drug-resistant strains, has severely impacted the effectiveness of current anti-malarial treatments. In response, the present study attempts to demonstrate the blood-stage anti-plasmodial action of 30 triazole derivatives designed based on molecular hybridisation technique, and physicochemical properties.
