Commercial Frozen Mice Used by Owners to Feed Reptiles are Highly Externally Contaminated with Salmonella Enteritidis PT8.

Salmonella remains one of the most prevalent zoonoses worldwide. Although salmonellosis is commonly associated with the consumption of contaminated food, it has been estimated that up to 11% of Salmonella infections overall are acquired from direct or indirect contact with animals, including reptiles. In 2016, an outbreak of Salmonella Enteritidis involving multiple cases, especially children, associated with reptile contact and contaminated feeder mice was reported in the United Kingdom. The aim of this st...

What WHO's List of Essential Diagnostics means for clinical microbiology laboratories and antimicrobial stewardship practice worldwide.

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...

Working in a laboratory is very difficult and needs special attention. Laboratory workers can be exposed to numerous potential hazards including chemical, biological, physical, and radioactive. That is why it is really important to follow the working principles in laboratories for the sake of the lab analyzers and others who work with them in the lab. Laboratory safety includes the use of certain laboratory rules, methods, infrastructures, and devices during work to protect the working person and the workin...

Antibody Responses to Salmonella in Pigs from Weaning Up to Marketing and Presence of Salmonella at Slaughter.

Salmonella is estimated to be one of the leading causes of enteric illness worldwide. Human salmonellosis is most frequently related to contaminated food products, particularly those of animal origin, such as pork. Pigs are often asymptomatic carriers of Salmonella, highlighting the importance of identifying high-prevalence farms and effective detection methods. The objectives of this study were to investigate Salmonella antibody responses and their association with on-farm shedding and Salmonella isolation...

Proposed Epidemiological Cutoff Values for Ceftriaxone, Cefepime, and Colistin in Salmonella.

We tested a diverse set of 500 isolates of nontyphoidal Salmonella enterica subsp. enterica from various animal, food, and human clinical sources for susceptibility to antimicrobials currently lacking epidemiological cutoff values (ECOFFs) set by the European Committee on Antimicrobial Susceptibility Testing. A consortium of five different laboratories each tested 100 isolates, using broth microdilution panels containing twofold dilutions of ceftriaxone, cefepime, and colistin to determine the minimum inhib...

Three Siphoviridae Salmonella enterica serovar Enteritidis bacteriophage are promising candidates for phage therapy.

Salmonella is a common and widely distributed foodborne pathogen that is frequently implicated in gastrointestinal infections. The emergence and spread of Salmonella strains resistant to multiple antibiotics poses a significant health threat, highlighting the urgent need for early and effective therapeutic strategies. We isolated a total of 32 phages from water samples and anal swabs from pigs. Of these, three phages that produced large, clear plaques were selected for further study using the following meth...

Outbreak of Hypervirulent Multi-Drug Resistant Klebsiella variicola causing high mortality in neonates in Bangladesh.

We report an outbreak by MDR K. variicola clone (ST771) in a Bangladeshi neonatal unit from October, 2016 to January, 2017, associated with high mortality (54.5%). During the outbreak, K. variicola ST771 acquired MDR plasmid harbouring blaNDM-1, linked to high exposure to ceftriaxone and amikacin in the NICU of DMCH.

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...

Herd-level prevalence of Salmonella Dublin among New York dairy farms based on antibody testing of bulk tank milk.

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...

A real-time PCR regimen for testing of environmental samples for Salmonella enterica subsp. enterica serovars of concern to the poultry industry with special focus on Salmonella Enteritidis.

A real-time PCR (qPCR) regimen, using up to six genetic targets, was developed for the rapid detection of Salmonella and in particular for the identification of S. Enteritidis. The test regimen was first evaluated using a reference culture collection of Salmonella to confirm the appropriateness of the selected targets including up to three genetic markers for discrimination of S. Enteritidis from other Salmonella serovars commonly found in poultry facilities. The qPCR procedure was then compared with cultur...

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...

Characterization of a colistin-resistant Salmonella enterica 4,5,12:i:- harbouring mcr-3.2 on a variant IncHI-2 plasmid identified in Canada.

We have identified a Salmonella enterica serotype 4,[5],12:i:- containing a mcr-3.2 in a patient who travelled to Thailand 1 month prior to the identification of it in Canada. The isolate was multidrug resistant, but remained susceptible to the carbapenems, amikacin and piperacillin/tazobactam. The mcr-3.2 was carried on a 261 Kb variant of the IncHI2 pWJ1. This report provides further evidence of the emergence of a ST34 colistin-resistant clone.

The relationships between the presence of biofilm-related genes and the biofilm formation capacity were evaluated. A total of 77 Salmonella strains in 8 different serotypes were assessed: Salmonella Agona (n = 43), Salmonella Senftenberg (n = 13), Salmonella Meleagridis (n = 8), Salmonella D...

Heat resistance of Salmonella Enteritidis under prolonged exposure to acid-salt combined stress and subsequent refrigeration.

Salmonella Enteritidis is a major foodborne pathogen exposed to various environmental and preservation stresses in the food chain. Because adaptive responses of viable bacterial cells in the presence of sublethal stress can induce cross-protection against different stresses, we investigated the heat resistance of Salmonella Enteritidis at 60 °C under prolonged exposure to acid-salt combined stress and subsequent refrigeration. Salmonella Enteritidis was grown in tryptic soy broth at four pH values (4.5, ...

Inactivation of Salmonella enterica and spoilage microorganisms in orange juice treated with dimethyl dicarbonate (DMDC).

Salmonella enterica is the pertinent pathogen associated with orange juice products that have resulted in numerous foodborne outbreaks. Although fresh orange juice typically has a pH below 4.0, which inhibits most pathogen growth, S. enterica can survive at low pH for extended periods. Additionally, fresh juice contains spoilage microorganisms such as natural yeasts and molds, which can grow at low pH, and may cause fermentation and product spoilage if left untreated. Numerous Salmonella outbreaks linked to...
