The RISKSUR EVA Tool (Survtool): a tool for the integrated evaluation of animal health surveillance systems

Publication date: Available online 18 September 2019Source: Preventive Veterinary MedicineAuthor(s): Marisa Peyre, Linda Hoinville, James Njoroge, Angus Cameron, Daniel Traon, Flavie Goutard, Clémentine Calba, Vladimir Grosbois, Alexis Delabouglise, Viktor Varant, Julian Drewe, Dirk Pfeiffer, Barbara HäslerAbstractInformation about infectious diseases at the global level relies on effective, efficient and sustainable national and international surveillance systems. Surveillance systems need to be regularly evaluated to ensure their effectiveness, the quality of the data and information provided, as well as to be able to allocate resources efficiently. Currently available frameworks for evaluation of surveillance systems in animal or human health often treat technical, process and socio-economic aspects separately instead of integrating them. The surveillance evaluation (EVA) tool, a support tool for the evaluation of animal health surveillance systems, was developed to provide guidance for integrated evaluation of animal health surveillance including economic evaluation. The tool was developed by international experts in surveillance and evaluation in an iterative process of development, testing and revision; taking into account existing frameworks and guidance, scientific literature and expert opinion elicitation. The EVA tool encompasses a web interface for users to develop an evaluation plan, a Wiki classroom to provide theoretical information on all required c...

This study demonstrated a maximum 2.91 log reduction of Salmonella cocktail in wheat flour treated with 395 nm pulsed LED for 60 min in a semi-closed system. Oxidation occurred in wheat flour after 30 and 60 min exposure to the 395 nm LED, which subsequently led to bleaching, and polymerization of gluten components through disulphide linkage. The water holding capacity of gluten was reduced by oxidation, and the contents of secondary structures were altered significantly after pulsed LED treatment, but the rheological properties were not deteriorated. The disulfide bond formation naturally happens during dough formation an...

(Malvaceae), popularly known as mutamba and guácimo, is a tree found in the Latina America, especially in Brazil and Mexico. Mutamba tree has been used as traditional medicine to treat several pathological conditions, such as diarrhoea, coughs, and gastrointestinal and cardiovascular disorders. Phytochemical studies on this plant have resulted in the disco...

EgeaAbstractKinetic models are nowadays a basic tool to ensure food safety. Most models used in predictive microbiology have model parameters, whose precision is crucial to provide meaningful predictions. Kinetic parameters are usually estimated based on experimental data, where the experimental design can have a great impact on the precision of the estimates. In this sense, Optimal Experiment Design (OED) applies tools from optimizat...

Jensen, Askild HolckAbstractSalmonella and Campylobacter represent the two most commonly reported zoonoses in EU and cause a significant health burden. The effects of a prototype steam treatment system (Deconizer) on reduction of aerobic bacteria, Salmonella Enteritidis and Campylobacter jejuni on chicken carcasses were investigated in the present study. In addition, the treated chicken carcasses were subjected to sensory analysis. The system tested is intended to be integ...

Bertzbach, Michael VeitAbstractIn contrast to human influenza viruses that replicate in the respiratory tract and are airborne transmitted, avian viruses also replicate in gut epithelial cells and are transmitted via the fecal-oral route. On this route, the virus is exposed to destructive fluids of the digestive tract, which are acidic and contain the proteases pepsin (gizzard) or chymotrypsin and trypsin (intestine). Only the latter enzyme activates virus by cleaving hemagglutinin (HA) into HA1 and HA2 subunits...

Background: Influenza virus is one of the most common respiratory pathogens for all age groups and may cause seasonal outbreaks. Our aim was to identify risk groups and factors associated with severe clinical course including mortality in children with influenza-related lower respiratory tract infection (LRTI). Methods: We conducted a retrospective study in children hospitalized with influenza virus LRTI from 2008 to 2018. Data on demographic features, influenza type, viral coinfection, primary and secondary bacterial infections (SBIs), time of onset of antiviral treatment, comorbidities, hospitalization length, pedia...

In this study, we detected for just the second time a SINV infection in a diseased wild bird (common wood pigeon) from Central Europe. SINV was isolated by cell culture and the complete SINV genome sequence was determined. Phylogenetic analyses revealed a close affiliation to SINV genotype I with a high similarity to human isolate sequences from Finland, Sweden and Russia. The isolate was genetically distinct from the first avian isolate suggesting the circulation of at least two different SINV strains in Germany.In order to reveal the infection frequency in SINV positive mosquito regions 749 bird blood samples were assaye...

We present the case of a 30-year-old Bissau-Guinean man with HIV-2 infection known for 16 years, irregularly treated, admitted with two weeks of fever, diarrhoea and cutaneous lesions. Examination revealed multiple subcutaneous nodes, Molluscum contagiosum-like lesions, generalized lymphadenopathy and painful palpation of the left iliac fossa. Laboratory tests showed severe nonhaemolytic anaemia and CD4+ count of 9/mm3, with normal creatinine and hepatic enzymes. Chest roentgenogram was unremarkable and a research for Mycobacterium tuberculosis by GeneXpert® was negative. Nonetheless, given the lack of further diagnost...

The objective of this study was to determine the in vitro antimicrobial activity of several organic acids and their derivatives against Gram-positive (G+) and Gram-negative (G−) bacteria. Butyric acid, valeric acid, monopropionin, monobutyrin, monovalerin, monolaurin, sodium formate, and ProPhorce—a mixture of sodium formate and formic acid (40:60 w/v)—were tested at 8 to 16 concentrations from 10 to 50,000 mg/L. The tested bacteria included G− bacteria (Escherichia coli, Salmonella enterica Typhimurium, and Campylobacter jejuni) and G+ bacteria (Enterococcus faecalis, Clostridium pe...

Publication date: Available online 7 October 2019Source: Pathology - Research and PracticeAuthor(s): Dominik Gross, Christina LaursAbstractThe Jewish pathologist Carl Julius Rothberger (1871–1945) is undoubtedly one of the most important representatives of his field. His studies on atrial fibrillation, the bundle branch block and arrhythmia perpetua in particular secured him a place in medical history. Rothberger also gave the name to an agar used to prove the neutral red reduction of salmonella (Rothberger-Scheffler agar).While Rothberger’s name is well known in pathology, his biography and his experiences of ...
