Identification of a KPC-9-producing Klebsiella pneumoniae ST258 cluster among KPC-2-producing isolates of an ongoing outbreak in Northwestern Greece: A retrospective study.

We identified the first nosocomial outbreak of KPC-9-producing isolates. Genetic comparison between our isolates and isolates of KPC-KP ST258 associated with Greece indicated that blaKPC-9 may have been replaced by blaKPC-2 on the pKpQiL- plasmid in KPC-KP ST258. The KPC-9-KP outbreak cluster is closely related to the KPC-2-KP outbreak in Greece. Screening for specific sublineages of KPC-KP ST258 by molecular tests may become an important tool in outbreak investigation.

Retrospective genome-wide comparisons of Salmonella enterica serovar Enteritidis from suspected outbreaks in Singapore.

The number of salmonellosis cases in Singapore has increased over the years. Salmonella enterica serovar Enteritidis has always been the most predominant serovar in the last five years. The National Public Health Laboratory assisted outbreak investigations by performing multi-locus variable number tandem repeat analysis (MLVA) on isolates that were collected at the time of the investigations. Isolates were defined as belonging to a particular cluster if they had identical MLVA patterns. Whilst MLVA has been...

Detection of Salmonella Infection in Chickens by an Indirect Enzyme-Linked Immunosorbent Assay Based on Presence of PagC Antibodies in Sera.

The outcomes of infection of humans and animals with Salmonella range from a persistent asymptomatic carrier state to temporal mild gastroenteritis or severe systemic infection. A rapid and accurate diagnostic test would help formulate strategies for effective prevention of their infections in the animal population. Current sequencing data predict that the outer membrane protein, PagC, is present in all common Salmonella serovars with sequence similarities of more than 98%. PagC sequences in other bacterial...

An Updated View on the Rck Invasin of Salmonella: Still Much to Discover.

Salmonella is a facultative intracellular Gram-negative bacterium, responsible for a wide range of food- and water-borne diseases ranging from gastroenteritis to typhoid fever depending on hosts and serotypes. Salmonella thus represents a major threat to public health. A key step in Salmonella pathogenesis is the invasion of phagocytic and non-phagocytic host cells. To trigger its own internalization into non-phagocytic cells, Salmonella has developed different mechanisms, involving several invasion factors...

Biofilm formation by Staphylococcus aureus and Salmonella spp. under mono and dual-species conditions and their sensitivity to cetrimonium bromide, peracetic acid and sodium hypochlorite.

The aim of this study was evaluated the biofilm formation by Staphylococcus aureus 4E and Salmonella spp. under mono and dual-species biofilms, onto stainless steel 316 (SS) and polypropylene B (PP), and their sensitivity to cetrimonium bromide, peracetic acid and sodium hypochlorite. The biofilms were developed by immersion of the surfaces in TSB by 10 d at 37°C. The results showed that in monospecies biofilms the type of surface not affected the cellular density (p>0.05). However, in dual-species biofilm...

Impact of the choice of reference genome on the ability of the core genome SNV methodology to distinguish strains of Salmonella enterica serovar Heidelberg.

Salmonella enterica serovar Heidelberg (S. Heidelberg) is one of the top serovars causing human salmonellosis. The core genome single nucleotide variant pipeline (cgSNV) is one of several whole genome based sequence typing methods used for the laboratory investigation of foodborne pathogens. SNV detection using this method requires a reference genome. The purpose of this study was to investigate the impact of the choice of the reference genome on the cgSNV-informed phylogenetic clustering and inferred isola...

Rapid detection and serovar identification of common Salmonella enterica serovars in Canada using a new pyrosequencing assay.

Serotyping of Salmonella enterica subspecies enterica is a critical step for foodborne salmonellosis investigation. We have developed a new assay to identify Salmonella enterica subsp. enterica (S. enterica) serovars based on a triplex polymerase chain reaction (PCR) with pyrosequencing for amplicon confirmation and phylogenetic discrimination of strain. The top 54 most prevalent serovars of S. enterica in Canada were examined with a total of 23 single nucleotide polymorphisms (SNPs) and/or variations (SNVs...

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...
