Harmonization of microbiology processes and standards: work in progress.

Clinical microbiology is a highly challenging technical discipline, which makes it difficult to harmonize processes and protocols. In addition, the lack of scientific consensus on some diagnostic algorithms and the need to address the diverse needs of different patient populations contribute to the lack of interlaboratory consistency. Laboratories utilize a number of measures and metrics, but the lack of standardized approaches and data collection means that they cannot effectively evaluate their performanc...

Modelling survival of Salmonella Enteritidis during storage of yoghurt at different temperatures.

The aim of this study was to evaluate the behaviour of Salmonella Enteritidis during the storage of yoghurt at different temperatures (4, 12, 20, and 25 °C), and to develop mathematical models to predict the behaviour of this bacterium as a function of storage temperature. Results indicated that Salmonella was able to survive longer during storage when temperature was low (e.g. 304 h at 4 °C, 60 h at 25 °C). The Geeraerd model with log-decrease and tailing was selected as the most suitable mode...

Septin-regulated actin dynamics promote Salmonella invasion of host cells.

Actin nucleators and their binding partners play crucial roles during Salmonella invasion, but how these factors are dynamically coordinated remains unclear. Here, we show that septins, a conserved family of GTPases, play a role during the early stages of Salmonella invasion. We demonstrate that septins are rapidly recruited to sites of bacterial entry and contribute to the morphology of invasion ruffles. Expression of Septin 2, Septin 7 and Septin 9 is required for efficient bacterial invasion. We found th...

Salmonella Dublin is an important cause of salmonellosis among dairy cattle and poses a considerable threat to public health. This serotype is increasingly being identified among bovine Salmonella isolates from clinical samples in the north-eastern United States, and these isolates are generally multidrug resistant. Our objective was to estimate the herd-level prevalence of Salmonella Dublin among dairy cattle herds throughout New York. Bulk tank milk samples from nearly all commercial dairy herds in New Yo...

Preparation of Powdered Infant Formula: Could Product's Safety be Improved?

The recent outbreak of Salmonella Agona linked to the consumption of infant formula (powdered formula) has rekindled the attention about the correct procedures for preparation and use of these products. International guidelines have already been published so far, particularly in association with Cronobacter sakazakii in early 2000's. FAO/WHO suggested to reconstitute formula with water at no less than 70°C. We therefore contaminated powdered formula with low levels of Salmonella spp. and C. sakazakii to ev...
