The occurrence and resistance of Shigella flexneri CECT4804 to acid stress in vitro and in vivo.

The ability to maintain intra‑cellular pH is crucial for many microbes mainly the enterobacteria to survive in diverse environments, particularly those that undergo fluctuations in pH. In this context, the growth and survival of Shigella flexneri at different acid pH values were evaluated to explain the response strategies involved in the adaptation of S. flexneri CECT4804 in acid stress conditions.

The Synbiotic Effect of Probiotics and Dried or Phycocyanin on Biofilm Formation by Typhimurium and .

This study aimed to evaluate the synbiotic effect of probiotics and dried or phycocyanin on autoaggregation, coaggregation, and the inhibition of biofilm formation by Typhimurium and on 96-well microtiter plates and Human colon carcinoma cells-116 surfaces. The results showed that the probiotics strains cultured in the presence of exhibited the highest autoaggregation values, ranging between 68.5 and 74.

Pathogenic Impacts of Strains on .

Regarding the economic importance of bivalve farming, a great deal of interest has recently been devoted to studying the pathogenesis of infectious diseases of these mollusks to prepare for public health emergencies. is one of these pathogens; it is a ubiquitous soil bacterium responsible for many types of gastrointestinal diseases associated with food. This study was conducted to determine the pathogenic effect of on .

Atypical Salmonella Typhimurium persistence in the pacific oyster, Crassostrea gigas, and its effect on the variation of gene expression involved in the oyster's immune system.

Salmonella is one of the most important pathogens involved in food intoxication outbreaks, and in many cases, the intoxication has been linked to shellfish which is typically consumed raw. While much is understood about the interactions between Salmonella and vertebrates, much less is known about its relationships with invertebrates, which could be an overlooked and important aspect to better understand the Salmonella interaction with its diversified hosts. The aim of this study was to investigate the effect of preadaptation in seawater microcosms during 12 months on Salmonella Typhimurium by determining its survival capacity within this mollusk over a period of 30 days.
