Listeria monocytogenes: dangers, prevention, and detection
Listeria monocytogenes: dangers, prevention, and detection
Listeria monocytogenes is described as a ubiquitous pathogenic bacteria, majorly responsible for isolated cases and outbreaks of listeriosis in humans and animals. When it first was discovered, it was only recognized as being dangerous to animals. Later in the 80s, due to several outbreaks of bacteria-contaminated food, this bacteria were seen as a threat to public health.

Screening of Spoilage Yeasts in Wine
Screening of Spoilage Yeasts in Wine
Winemaking is a non-sterile process and the role of yeast in fermentation is essential to the production of the fermented alcoholic beverages. Wine fermentation is a complex microbiological process in which specific yeasts strains are selected to obtain the desired fermentation characteristics – flavor and aroma – in the final product. Saccharomyces cerevisiae is the main microorganism involved, due to their fast fermentation rates and ability to survive in the harsh environmental conditions of wine.

Hop latent viroid (HLVd), Lettuce Chlorosis Virus (LCV) and Cannabis Cryptic Virus (CanCV) in Cannabis
Cultivation of cannabis plants (Cannabis sativa L., marijuana) has taken place worldwide for centuries. Recently, in some countries, we have seen the legalization of cannabis for the medical and recreational markets, sparking interest in large-scale cultivation. This increase in production has seen an increase in the incidence and severity of plant pathogens causing several diseases.
