Extensive multivariate dataset characterizing bacterial community diversity and contamination level in a large number of conventional broilers carcasses after air chilling and refrigerated storage.

The article provides extensive data on the diversity of bacterial communities collected on 480 conventional broiler carcasses from a French slaughterhouse between October 2022 and January 2023. Half of the carcasses were collected from the first slaughter batches and the other half from the later batches to highlight possible microbial cross-contamination between carcasses along the slaughter chain. and the Total Viable Count were quantified on agar plates before and after 7 days of refrigerated storage to estimate the contamination level of broiler carcasses.

No evidence for a relationship between farm or transformation process locations and antibiotic resistance patterns of Pseudomonas population associated with rainbow trout (Oncorhynchus mykiss).

Aims: Study the relationship between antibiotic resistance patterns of Pseudomonas isolated from farmed rainbow trout fillets and farm or transformation process locations.

Methods And Results: Pseudomonas strains were isolated from rainbow trout sampled in two differently located farms and filleted in laboratory or in a processing factory. One hundred and twenty-five isolates were confirmed as belonging to Pseudomonas using CFC selective media, Gram staining, oxidase test and quantitative polymerase chain reaction methods.

Quantification of Viable in Cold-Smoked Salmon Using PMA/PMAxx-qPCR.

The aim of this study was to develop a rapid and accurate PMA-qPCR method to quantify viable in cold-smoked salmon. is one of the main food spoilage bacteria. Among seafood products, cold-smoked salmon is particularly impacted by spoilage.

Symbiont dynamics during the blood meal of Ixodes ricinus nymphs differ according to their sex.

Ticks harbour rich and diverse microbiota and, among the microorganisms associated with them, endosymbionts are the subject of a growing interest due to their crucial role in the biology of their arthropod host. Midichloria mitochondrii is the main endosymbiont of the European tick Ixodes ricinus and is found in abundance in all I. ricinus females, while at a much lower density in males, where it is even absent in 56 % of the individuals.

Characterization of Bacterial Communities of Cold-Smoked Salmon during Storage.

Cold-smoked salmon is a widely consumed ready-to-eat seafood product that is a fragile commodity with a long shelf-life. The microbial ecology of cold-smoked salmon during its shelf-life is well known. However, to our knowledge, no study on the microbial ecology of cold-smoked salmon using next-generation sequencing has yet been undertaken.
