The statement of claim alleged the resort acted with a “wanton, callous and reckless regard” for the safety of the class members who are seeking $5 million for negligence and breach of contract.
With the ceeramTools assays for detecting and identifying NOROVIRUS in any type of food matrices and Surfaces, it is now possible to anticipate and organize regular controls with your molecular laboratory.
Adsorbed on particles, they can survive in different kind of environment for a long period. Food samples can be contaminated via food handlers or by the environment. Due to their structural properties, norovirus can survive to different food process. The consumption of contaminated food can lead to human outbreak. There is no cell culture system available for the multiplication of human noroviruses.

Norovirus
Genogroup I and II noroviruses are non enveloped and single strand RNA viruses. These human enteric viruses are responsible for most of viral gastroenteritis outbreaks. They are pathogenic for all age groups of the population. These viruses are very infectious; one to ten viral particles are sufficient to get sick. Their mode of transmission is the feco-oral route. After excretion in human stool, due to their structural properties, noroviruses can resist to different physical and chemical treatment.Adsorbed on particles, they can survive in different kind of environment for a long period. Food samples can be contaminated via food handlers or by the environment. Due to their structural properties, norovirus can survive to different food process. The consumption of contaminated food can lead to human outbreak. There is no cell culture system available for the multiplication of human noroviruses.
Detection of noroviorus
The detection by ELISA is not recommended due to norovirus genetic diversity and its lack of sensitivity. Molecular techniques (real time RT-PCR) are the methods of choice for NoV detection after extraction and viral RNA purification from the sample.Norovirus detection kits
Detection kit is based on real-time PCR. Real-time PCR is a proven method for pathogen detection and has been applied successfully to a wide range of foodborne pathogens. The method tests for food pathogens by amplifying and detecting a RNA target sequence that is specific to Norovirus. Detection is quick, simple, and with outstanding sensitivity and specificity. Shelf-Life : 360 days.jeudi 27 septembre 2012

Wild boars are reservoir of HEV: High prevalence among forestry workers in eastern France
Wild boars are reservoir of HEV: High prevalence among forestry workers in eastern France
The prevalence of HEV was found to be 14 percent among wild boar, about half that in pigs, says principal investigator Pierre Coursaget of the University of Tours, France. An earlier study found 12 percent prevalence among boar in The Netherlands. Among humans in the current study, the prevalence of anti-HEV antibodies increases with age, and varies with occupation and geographic location within eastern France. "The frequency of HEV infections in humans did not correlate with the number of pigs, locally, but there is good correlation with the number of car accidents due to wild boars," a surrogate for contact between humans and wild boars, says Coursaget.

Pourquoi Norovirus dépasse les pathogènes Salmonella et E. coli?
Pourquoi Norovirus supplante les pathogènes Salmonella et E. coli
Dans un article de la revue Food Quality du 7 Août 2012, il est indiqué que Norovirus émerge comme deuxième cause de décès lié à la gastro-entériteNorovirus, l'agent pathogène humain parfait
Un récent rapport du "Journal of Infectious Diseases" souligne pourquoi les norovirus représentent "l'agent pathogène humain parfait».Dans une publication du JID (http://jid.oxfordjournals.org/content/205/11/1639.abstract), une contamination à Norovirus est décrite, impliquant neuf membres de l'équipe féminine de football (Lien). Le patient de référence, une adolescente, a développé des vomissements et de la diarrhée en séjournant dans un hôtel lors d'un tournoi hors de la ville et rentra chez lui le lendemain sans aucun contact supplémentaire avec son équipe. Trois jours plus tard, sept autres membres de l'équipe sont tombés malades avec les mêmes symptômes, qui ont finalement été tracées à une infection à norovirus associée à des collations emballées conservées dans un sac d'épicerie réutilisable, dans une chambre d'hôtel où séjournait l'équipe.
Les norovirus, si difficile à contrôler
Facilement propagé par un certain nombre de moyens différents, il suffit d'une petite quantité de norovirus pour rendre quelqu'un malade. Les personnes infectées ne semblent pas développer d'immunités durables. Elles peuvent donc être infectées à plusieurs reprises tout au long de leur vie.
Les décès liés aux gastro-entérites doublent
En Mars dernier, un rapport du CDC indique que les décès liés aux gastro-entérites ont doublé entre 1999 et 2007. Bien que le Clostridium difficile ait été la principale cause de décès associé à la gastro-entérite, cette étude a montré que les norovirus sont probablement la deuxième cause infectieuse. Norovirus est responsable d'environ 800 décès chaque année aux États-Unis (Lire le rapport).
Un vaccin pour Norovirus
En Décembre 2011, le New England Journal of Medicine a publié les résultats d'une étude sur 98 personnes. Seuls 37% des personnes du groupe vacciné ayant ensuite été exposées à des norovirus ont développé des symptômes de gastro-entérite.Des causes multiples : une approche intégrée et globale
Mais même un vaccin, qui serait le plus susceptible d'être utilisé dans les milieux à haut risque comme les maisons de retraite, les garderies, ne pourra pas éliminer les norovirus. Toute tentative de contrôler les norovirus nécessite d'employer une approche à plusieurs volets.

MRSA case reported at Westlake middle school
MRSA case reported at Westlake middle school - 19 Action News|Cleveland, OH|Breaking News, Weather, Exclusives
The Westlake School District has sent a letter home to parents about a MRSA case at Lee Burneson Middle School.
What is MRSA
Methicillin-resistant Staphylococcus Aureus (MRSA) is a type of staph bacteria that is resistant to certain antibiotics called beta-lactams. These antibiotics include methicillin and other more common antibiotics such as oxacillin, penicillin, and amoxicillin. In the community, most MRSA infections are skin infections. More severe or potentially life-threatening MRSA infections occur most frequently among patients in healthcare settings. While 25% to 30% of people are colonized* in the nose with staph, less than 2% are colonized with MRSA (Gorwitz RJ et al. Journal of Infectious Diseases. 2008:197:1226-34.). Sometimes it is referred to as the "Super Bug."

Typing MRSA
Multi Locus VNTR Analysis (MLVA) is a PCR based typing method that relies on the inherent variability found in many regions of repetitive DNA called VNTR (Variable Number Tandem Repeat) which represent sources of genetic polymorphism. The MLVA assay for S. aureus examines 16 loci. Thus, each isolate is defined by a 16-digit numeric code corresponding to the number of repeats at each VNTR.

Virus de l'Hépatite A : les clients d'un restaurant contaminés dans la Sarthe
Epidémie au virus de l'hépatite A dans la Sarthe
Ouest France dans un article du 4 septembre 2012 nous fait part que l'ARS (Agence Régionale de Santé) des Pays de la Loire vient d'adresser un courrier aux médecins et laboratoires d'analyses de la région du Mans, conséquemment à une épidémie d'hépatite A (virus de l'hépatite A.
Comme indiqué dans le Maine Libre, aucune autre information n’a filtré pour l’instant pour identifier plus précisément l’établissement visé. Jointe hier, la direction de la communication de l’ARS, confirmant la réalité de ce courrier, s’est refusée à communiquer le moindre renseignement sur les coordonnées du restaurant concerné.
Le Virus de l'Hépatite A
Le virus de lʼhépatite A est un virus non enveloppé à ARN simple brin. Le délai dʼincubation est en moyenne dʼun mois. La sévérité des signes cliniques augmente avec lʼâge allant de cas asymptomatique chez les jeunes enfants (moins de 6 ans) à des cas dʼhépatites aiguës voire fulminantes. La transmission par voie féco-orale est la plus habituelle. Les aliments peuvent être contaminés par un manipulateur ou via lʼenvironnement. La consommation dʼaliments contaminés peut conduire à des épidémies dans la population. Grâce à ses propriétés structurales, le virus de lʼhépatite A peut persister à différents procédés alimentaires et à différents traitements physico-chimiques. Il nʼexiste pas de traitement curatif spécifique, mais un vaccin est disponible.Voir la fiche de danger biologique de l'ANSES pour le virus de l'hépatite A
Les outils et méthodes pour détecter le virus de l'hépatite A dans les aliments ou l'eau
Le diagnostic par culture cellulaire est difficile. La détection par RT-PCR en temps réel, après extraction et purification de lʼARN viral, est une méthode de choix compte tenu de sa rapidité et de sa sensibilité.
La trousse de diagnostic moléculaire ceeramTools est basée sur la PCR temps réel. La PCR temps réel est une méthode éprouvée pour la détection des pathogènes et a été utilisée avec succès sur un large panel de pathogènes. La méthode teste pour les pathogènes par amplification et détection des séquences cibles ARN spécifiques du virus de l'hépatite A. La détection est rapide, simple, avec une sensibilité et une spécificité excellente.
La limite de détection de ce kit varie de 5 à 10 copies selon la qualité des acides nucléiques extraits.
