Article Synopsis
- The Harveyi clade of fish and shellfish pathogens significantly impacts aquaculture profits and can also infect humans; this study assesses their presence in southeastern USA waters.
- Environmental DNA samples from water and sediments in Georgia revealed that pathogen virulence gene concentrations were much higher in sediments than in water, with specific seasonal trends in gene presence.
- The study found that two groups of virulence genes adapted differently to environmental factors like temperature, pH, and salinity, influencing their diversification and potential stratification into ecological niches.
Aims: To understand spatial-temporal distribution of Vibrio parahaemolyticus and Vibrio vulnificus in triploid Crassostrea virginica in off-bottom aquaculture.
Methods And Results: Oysters, sediments and water were seasonally collected in Georgia, USA. V.
Efficient removal of bacteria from aqueous media with kaolinite and diatomaceous earth products.
J Appl Microbiol
September 2020
Aims: To understand the relationships between physical and chemical parameters of kaolinite and diatomaceous earth, and their capacities to remove bacteria from aqueous media. To determine the optimal aqueous media parameters for use of these products in water disinfection processes.
Methods And Results: Seven kaolinite and three diatomaceous earth products were evaluated.
Intertidal creeks form the primary hydrologic link between estuaries and land-based activities on barrier islands. Fecal indicators Enterococcus spp. (Entero1), pathogens Shigella spp.

Methods And Results: Run-offs from a forested area and a small settlement in a tidal creek' s watershed were compared for bacterial composition and profiles of 16 tetracycline resistance (TRG), eight virulence (VG) and integrase1 and 2 genes. Integrase 1 gene was detected only once.
