Anti-Biofilm Extracts and Molecules from the Marine Environment.

Pathogenic bacteria and their biofilms are involved in many diseases and represent a major public health problem, including the development of antibiotic resistance. These biofilms are known to cause chronic infections for which conventional antibiotic treatments are often ineffective. The search for new molecules and innovative solutions to combat these pathogens and their biofilms has therefore become an urgent need.

Antibiofilm Activity of the Marine Probiotic Bacillus subtilis C3 Against the Aquaculture-Relevant Pathogen Vibrio harveyi.

V. harveyi is a well-known pathogen-inducing vibriosis, especially for shrimp, fish, and invertebrates. Its virulence is related to biofilm formation and this negatively impacts the aquaculture industry.

Genetic Insights into Biofilm Formation by a Pathogenic Strain of .

The genus includes bacteria widely distributed in aquatic habitats and the infections caused by these bacteria can affect a wide range of hosts. They are able to adhere to numerous surfaces, which can result in biofilm formation that helps maintain them in the environment. The involvement of the biofilm lifestyle in the virulence of pathogens of aquatic organisms remains to be investigated.

Sensitivity of Legionella pneumophila to phthalates and their substitutes.

Phthalates constitute a family of anthropogenic chemicals developed to be used in the manufacture of plastics, solvents, and personal care products. Their dispersion and accumulation in many environments can occur at all stages of their use (from synthesis to recycling). However, many phthalates together with other accumulated engineered chemicals have been shown to interfere with hormone activities.
