The study of interaction between fish cage culture and sediment population dynamics heterotrophic bacteria in the southern Caspian Sea (Nowshahr region)

Interactions between bacteria and their host represent a full continuum from pathogenicity to mutualism. From an evolutionary perspective, host-bacteria relationships are no longer considered a two-component system but rather a complex network. In this study, we focused on the relationship between brook charr (Salvelinus fontinalis) and bacterial communities developing on skin mucus. We hypothe...

Phage therapy may represent a viable alternative to antibiotics to inactivate fish pathogenic bacteria. Its use, however, requires the awareness of novel kinetics phenomena not applied to conventional drug treatments. The main objective of this work was to isolate bacteriophages with potential to inactivate fish pathogenic bacteria, without major effects on the structure of natural bacterial co...

Some commensal intestinal bacteria in humans and mice are coated with secretory immunoglobulin A (S-IgA). It has been suggested that the S-IgA coating of commensal bacteria does not occur at random and thus identification of S-IgA-coated bacterial genera/species should help in elucidating the interaction between S-IgA and commensal intestinal bacteria, but no method of identifying the genera/sp...

Normally, the gastrointestinal epithelium provides a semi-permeable barrier which allows nutrients to be absorbed while preventing larger, potentially toxic, antigenic, or pathogenic molecules or organisms from crossing into the bloodstream. Pathogenicallyincreased intestinal permeability predisposes the individual to diffusion of antigenic food molecules and translocation of bacteria and/or ye...

The members of the Aeromonas genus are ubiquitous, water-borne bacteria. They have been isolated from marine waters, rivers, lakes, swamps, sediments, chlorine water, water distribution systems, drinking water and residual waters; different types of food, such as meat, fish, seafood, vegetables, and processed foods. Aeromonas strains are predominantly pathogenic to poikilothermic animals, and t...

in this study, the essential oil (eo) of pistacia atlantica subsp. kurdica was added at the rate of 10 g/kg of daily diet of rainbow trout and its effect on gut microbiota (enterobacteriaceae, lactobacillus spp., total count), growth performance and antioxidant status of rainbow trout fillet was investigated. sixty apparently healthy rainbow trout with an approximate weight of 150 g ±3.5 were r...

Nonpathogenic rhizobacteria can induce a systemic resistance in plants that is phenotypically similar to pathogen-induced systemic acquired resistance (SAR). Rhizobacteria-mediated induced systemic resistance (ISR) has been demonstrated against fungi, bacteria, and viruses in Arabidopsis, bean, carnation, cucumber, radish, tobacco, and tomato under conditions in which the inducing bacteria and ...
