Staphylococcal food poisoning represents the most prevalent foodborne intoxication worldwide. It is caused by oral intake of enterotoxins preformed by Staphylococcus aureus in food. The relevance of newly described enterotoxins in outbreaks of staphylococcal food poisoning is controversially discussed. Although the staphylococcal enterotoxins SEG, SEI, SEM, SEN, and SEO elicit emesis in a monkey feeding assay, there has been no conclusive proof of their emetic activity in humans. In this study, we provide further evidence suggesting that one of these enterotoxins or a combination of SEG, SEI, SEM, SEN, and SEO cause staphylococcal food poisoning. We investigated two outbreaks registered with the Swiss Federal Office of Public Health, in which only Staphylococcus aureus strains harboring the egc cluster, including seg, sei, sem, sen, and seo linked to typical signs of staphylococcal food poisoning were isolated. The outbreaks were caused by consumption of raw goat cheese and semi-hard goat cheese, and
Staphylococcal food poisoning (SFP) is one of the most probably occurring food-borne diseases caused by Staphylococcus aureus enterotoxins.
Staphylococcal food poisoning is a gastrointestinal illness. It can be transmitted by food workers and is also found in unpasteurized milk and cheese products. Some examples of foods that have caused staphylococcal food poisoning are sliced meat, puddings, pastries and sandwiches.
Staphylococcus aureus is an important pathogen in humans and animals because this bacterium produces a wide variety of exotoxins, including staphylococcal enterotoxins (SEs) and toxic shock syndrome toxin 1 (TSST-1) (8, 15). SEs are emetic toxins and are causative agents in staphylococcal food poisoning in humans, although their mechanisms of emetic activity are not fully understood (5). Also, SEs and TSST-1 are superantigens (SAgs), which have the ability to stimulate large populations of T cells that have a particular Vβ element of the T-cell receptor (TCR). This gives rise to symptoms that are characteristic of toxic shock syndrome in humans. Five major serological types, SEA through SEE, have been characterized (5). However, in recent years, many new types of SE (i.e., SEG, SEH, SEI, SEJ, SEK, SEL, SEM, SEN, SEO, SEP, and SEQ) have been reported (10, 12, 13, 17, 22, 23, 24, 27, 30, 31). In addition, the determination of the complete genome sequences of several S. aureus strains has revealed ...
The presence of Staph aureus toxin in food may lead to food poisoning. The onset of symptoms in staphylococcal food poisoning is usually rapid and in many cases acute, depending on individual susceptibility to the toxin, the amount of contaminated food eaten, the amount of toxin in the food ingested, and the general health of the victim. The most common symptoms are nausea, vomiting, retching, abdominal cramping, and prostration ...
Staphylococcal food poisoning is one of the most prevalent causes of foodborne intoxication worldwide. It is caused by ingestion of enterotoxins formed by Staphylococcus aureus during growth in the food matrix. Following a recall of barbecue cheese due to the detection of staphylococcal enterotoxins in Switzerland in July 2015, we analyzed the production process of the respective dairy. Although most cheese-making processes involve acidification to inhibit the growth of pathogenic bacteria, barbecue cheese has to maintain a pH ,6.0 to prevent undesired melting of the cheese. In addition, the dairy decided to retain the traditional manual production process of the barbecue cheese. In this study, therefore, we aimed to (1) trace Staph. aureus along the barbecue cheese production process, and (2) develop a sustainable strategy to inhibit growth of Staph. aureus and decrease the risk of staphylococcal food poisoning without changing the traditional production process. To this end, we traced Staph. ...
Staphylococcal enterotoxins (SEs) account for a substantial number of food-poisoning outbreaks. European legislation (Commission Regulation 1441/2007) stipulates the reference procedure for SE analysis in milk and dairy products, which is based on extraction, dialysis concentration and immunochemical detection using one of two approved assays (VIDAS(®) SET2, Ridascreen(®) SET Total). However, certified reference materials (CRMs) are lacking to support laboratories in performing reliable detection of Staphylococcus aureus enterotoxin A (SEA) in relevant matrices at sub-nanogram per gram levels. The certification of a set of three reference materials (blank and two SEA-containing materials) for testing of the presence/absence of SEA in cheese is described. The reference procedure was applied in an intercomparison with 15 laboratories, and results were reported in a qualitative manner (presence or absence of SEA in the sample). No false-negative or false-positive results were obtained. The certified
ABSTRACT. Food-borne diseases are of major concern worldwide. To date, around 250 different food-borne diseases have been described, and bacteria are the causative agents of two thirds of food-borne disease outbreaks. Among the predominant bacteria involved in these diseases, Staphylococcus aureus is a leading cause of gastroenteritis resulting from the consumption of contaminated food. Staphylococcal food poisoning is due to the absorption of staphylococcal enterotoxins preformed in the food. Here, we briefly review the latest data on staphy-lococcal enterotoxins and some papers exemplifying the interactions between S. aureus and the food matrix; environmental factors affecting staphylococcal enterotoxin production are discussed.. Key words: Staphylococcus aureus, Food poisoning, Enterotoxins, Food matrix. ...

The results obtained with the SEB-SEC chimeras were quite surprising, because only SEB mutant V26Y had a higher affinity (Kd = 19 μM, taken as an average of sedimentation equilibrium and BIAcore measurements) than wild-type SEB (Kd = 130 μM). The two other SEB single mutants, L20T and Y91V, did not show improved binding and the triple mutant did not show any detectable binding to the 14.3.d β chain. Since alanine-scanning mutagenesis of SEC3 implicated Y26 as functionally important, it is reasonable that replacement of the valine that is present in wild-type SEB by the bulkier tyrosine should increase the number of van der Waals contacts to the β chain and hence improve the affinity of that mutant. Other studies also revealed a key role of residue 26 in SEC 1-3 and SEB in the specificity of these SAGs for different human TCRs. Thus, SEB and SEC1 react strongly with human Vβ3 but not with Vβ13.1, whereas SEC3 and SEC2 bind well to Vβ13.1 but only weakly with Vβ3 ((8)). Site-directed ...
Staphylococci are a worldwide cause of human and animal infection and are considered to be of the most common causes of infections in birds. Enterotoxins produced by some staphylococcal species were recognized as a causative agent of staphylococcal food poisoning (SFP). Only enterotoxins produced by Staphylococcus aureus were as yet well characterized. Much less is known about enterotoxigenic potential of coagulase-negative species of genus Staphylococcus (CNS). It has been reported that enterotoxigenic CNS strains have been associated with human and animal infections and food poisoning. Samples collected from chicken production cycle (un hatched eggs, baby chicks, broilers, chicken meat and table eggs) in Luxor, Egypt were tested to investigate the presence of Staphylococcus species and detection of their enterotoxines genes with more special attention for detection of methicillin resistance gene (mec A). Samples were tested for S. aureus and CNS on the basis of cultural and biochemical ...
S. aureus Enterotoxin D antibody LS-C132246 is an unconjugated rabbit polyclonal antibody to staphylococcus aureus S. aureus Enterotoxin D. Validated for ELISA.
Staphylococcus aureus represents a public health challenge all over the world. Therefore, this study aims to analyze the prevalence of five genes (sea, seb, sec, see and seg) encoding the staphylococcal enterotoxins in S. aureus isolated from different sources and to evaluate the association of these toxins in comparison to susceptibility towards 12 antimicrobials; antimicrobial susceptibility was conducted by disc diffusion method. Detection of staphylococcal enterotoxins was performed by PCR and the ability to express these genes was assessed among isolates by RT-PCR. The most common enterotoxin gene was sea gene (66%), followed by seb, sec, see and seg (38%, 23%, 19% and 5%) respectively. Expression of sea, seb and seg genes was variable. However, sec and see genes were not expressed by any of the tested isolates. No statistically significant association exists between (seb, sec and see) and isolation sources, while the sea was significantly associated with clinical isolates. High significant

Background: It has been revealed that Staphylococcus aureus enterotoxin B (SEB) may feature anti-cancer and anti-metastatic advantages due to its ability to modify cell immunity processes and signaling pathways. Glioblastoma is one of the most aggressive human cancers; it has a high mortality nature, which makes it an attractive area for the development of novel therapies. Objectives: We examined whether the SEB could exert its growth inhibitory effects on glioblastoma cells partially through the manipulation of a key tumor growth factor termed transforming growth factor-beta (TGF-β). Materials and Methods: A human primary glioblastoma cell line, U87, was treated with different concentrations of SEB. The cell quantity was measured by the MTT assay at different exposure times. For molecular assessments, total ribonucleic acid (RNA) was extracted from either non-treated or SEB-treated cells. Subsequently, the gene expression of TGF-β transducers, smad2/3, at the messenger RNA (mRNA) level, was ...
BACKGROUND & AIMS Activation of lamina propria T cells with pokeweed mitogen in human fetal gut explant cultures results in severe mucosal injury. In the same system, Staphylococcus aureus enterotoxin B produces villus atrophy and crypt cell hyperplasia. The aim of this study was to examine the ability of interleukin (IL)-10 to modify these changes. METHODS Mucosal pathology and lamina propria glycosaminoglycans were assessed histologically, and CD3(+), CD25(+) and alpha-actin smooth muscle-positive cells were determined by immunohistochemistry. Reverse plaque assays and quantitative reverse-transcriptase polymerase chain reaction were used to analyze the cytokine response. Matrix metalloproteinase production was analyzed by Western blotting, in situ hybridization, and zymography. RESULTS Both experimental enteropathies produced mucosal damage, although injury was greater after pokeweed mitogen activation than S. aureus enterotoxin B. In both cases, the increase in cytokine-secreting cells and

Staphylococcus aureus is one of the most significant pathogens causing nosocomial and community acquired infections. Among the secreted Staphylococcal virulence factors, there is a growing list of enterotoxins which can induce gastroenteric syndrome and toxic shock syndrome. Here we used PCR for the detection of genes encoding Staphylococcal enterotoxins A, B, C, D, E (SEA, SEB, SEC1, SED and SEE) of S. aureus. SEA-SEE were selected because they are 5 classically Described enterotoxins of S. aureus and because they were detected by Latex agglutination. We investigated 50 isolates of S. aureus drived from scar of patients. The presence of enterotoxin genes was found in 37 (74%) of total number of 50 isolates, for one or more enterotoxin genes. The PCR is more sensitive because it offers the possibility for determining enterotoxin as on a genotypic basis ...
The causative organism multiplies in the food before ingestion; the pathogenesis is organism specific. Staphylococcal enterotoxins form in foods held at room temperature. They act on the gastric mucosa, producing hyperemia, erosion, petechiae, and purulent exudate. C. perfringens reproduces rapidly in cooled and reheated food and acts on the epithelial layer of the ileum, increasing absorption of fluid, sodium, and chloride and inhibiting glucose absorption. V. parahaemolyticus multiplies in uncooked seafood and invades the intestinal tissue, producing necrosis, ulceration, and granulocytic infiltration of the mucosa. B. cereus, an aerobic spore, multiplies in foods held at room temperature and attacks either the gastric or intestinal mucosa. C. botulinum forms a toxin in improperly processed foods in anaerobic conditions; it is a neurotoxin that impairs autonomic and voluntary neurotransmission and causes muscular paralysis.. ...
BACKGROUND: Staphylococcal foodborne intoxication is the most common cause of foodborne illnesses by Staphylococcus aureus strains and most are caused by the enterotoxins of S. aureus. Staphylococcal enterotoxin A (SEA) is the most frequently responsible for staphylococcal food poisoning outbreaks. From a food safety and human health point of view, lactic acid bacteria (LAB) may provide a promising strategy in the fight against S. aureus.OBJECTIVES: Increasing product shelf life, and enhancing the safety of food and human health using natural microflora are the aims of this study. METHODS: In this study we evaluate the inhibitory effects of three lactobacillus strains isolated from yoghurt, namely lactobacillus acidophilus, lactobacillus fermentum and lactobacillus paracasei, on the growth and enterotoxin production of Staphylococcus aureus by co-incubating each strain with enterotoxigenic S. aureus at two temperatures: 25 and 35°C. Expression of the SEA gene of S. aureus was assessed by real-time PCR.

The crystal structure of staphylococcal enterotoxin type A (SEA), a 27 kDa monomeric protein, was determined to 1.9 Å resolution with an R-factor of 19.9% by multiple isomorphous replacement. SEA is a two domain protein composed of a β-barrel and a β-grasp motif demonstrating the same general structure as staphylococcal enterotoxins SEE and TSST-1. Unique for SEA, however, is a Zn2+ coordination site involved in MHC class II binding. ...

DISCLAIMER: 1. This pie does not contain actual crack. 2. This picture does not do it justice.. A few weeks ago my friend Carly asked if I had ever tasted Crack Pie. Crack Pie? Huh? She then explained its some crazy addictive pie shed heard about, and that you can buy it online from Momofuku Milk Bar for $44. Yes, $44. As fate would have it, the LA Times ran an article about the pie the very next day, and included in the article was the recipe. I promised Carly I would make it. So when I got invited to a friends Oscar party, I figured hey, why not try out the Crack Pie? Since the recipe yields two pies, I had grand plans of tasting one pie then freezing the rest of it so Carly could try it, and bringing the other pie to the party. Of course, my oven had other plans and I burned the first pie beyond repair (totally my fault, I set the oven incorrectly). This meant I only had one pie to work with and I would be bringing something I had never tasted to the party. To make matters worse, I read ...

Coagulase is a protein enzyme produced by several microorganisms that enables the conversion of fibrinogen to fibrin. In the laboratory, it is used to distinguish between different types of Staphylococcus isolates. Importantly, S. aureus is generally coagulase-positive, meaning that coagulase negativity usually excludes S. aureus. However it is now known that not all S. aureus are coagulase-positive. It is also produced by Yersinia pestis. Coagulase reacts with prothrombin in the blood. The resulting complex is called staphylothrombin, which enables the enzyme protease to convert fibrinogen, a plasma protein produced by the liver, to fibrin. This results in clotting of the blood. Coagulase is tightly bound to the surface of the bacterium S. aureus and can coat its surface with fibrin upon contact with blood. The fibrin clot may protect the bacterium from phagocytosis and isolate it from other defenses of the host.The fibrin coat can therefore make the bacteria more virulent. Bound coagulase is ...

The T cell receptor (TCR) V beta-determining region of two bacterial superantigens, staphylococcal enterotoxin A (SEA) and SEE, has been mapped to the COOH-terminal region of SEA and SEE using a panel of recombinant SEA/SEE hybrids. Total TCR V beta mRNA enrichment in human peripheral blood T cell cultures was determined by a novel single-tube amplification technique using a redundant V beta-specific primer. SEA routinely enriched mRNA coding for hV beta 1.1, 5.3, 6.3, 6.4, 6.9, 7.3, 7.4, and 9.1, while SEE, which is 83% homologous to SEA, enriched hV beta 5.1, 6.3, 6.4, 6.9, and 8.1 mRNA. Exchanging residues 206 and 207 was sufficient to convert in toto the TCR V beta response of human peripheral T lymphocytes. In addition, an SEA-reactive murine T cell line, SO3 (mV beta 17), unresponsive to wild-type SEE responded to SEE-S206N207, while an SEE-specific human T cell line, Jurkat (hV beta 8.1), unresponsive to SEA was stimulated strongly by SEA-P206D207. Exchanging all other regions of SEA and ...
In the present study, we introduce a novel hybrid sandwich-ALISA employing chicken IgY and ssDNA aptamers for the detection of staphylococcal enterotoxin B (SEB). at 250?ngmL?1, could able to detect 100?ngmL?1 antigen. We further combined both the probes to prepare a hybrid sandwich aptamer linked immune sorbent assay (ALISA) wherein the IgY as capturing molecule and biotinylated aptamer as revealing probe. Limit of detection (LOD) for the developed method was determined as 50?ngmL?1. Further, developed method was evaluated with artificially SEB spiked milk and natural samples and obtained results were validated with PCR. In conclusion, developed ALISA method may provide cost-effective and robust detection of SEB from food and Rabbit polyclonal to VDAC1. environmental samples. is a major human pathogen that elicits wide range of exotoxins that are responsible for diverse disease symptoms in humans.

Still no strawberry in my neck of the woods. WOW, indeed Krispy Kreme does make fruit pies. My local Kroger has their donuts but I never buy any, sure I would have noticed the pies if they had them, tho. I will look into this! BTW, my inkling was indeed correct. Little Debbie and JJs (JTM Foods)pies are one and the same.  Got both from a sara Lee outlet(not sure where they fit in, oddly enough) Hence, why Little Debbies pies say distributed by rather than made by.  Also explains why they offer the exact same flavors and have the exact same nutrional information.  Surprised Debbies outsources their pies, but JJs does offer a fine product and Debbies has such a massive roster of treats already. The pies from Aldis (Bakers Treat) also come from JJs....only apple and cherry they offer I think, tho.  And they do a bunch of other private labels for other stores as well.  I found a really informative article online about their operation---quite cool.
