A new vaccine against Enteritidis Salmonella

17.12.2004


Javier Ochoa Repáraz has developmed an acellular vaccine aginst Salmonella enteritidis.

This involves a world pandemia considered to be the most importante zoonosis or illness/infection transmissible salmonellosis by animals to humans under natural conditions. It is estimated that the incidence of acute worldwide is more than a thousand million cases per annum and causes three million deaths.

The project developed by Javier Ochoa at the University of Navarre Faculty of Science centred on the investigation of a new vaccine based on the encapsulation of the components of the Salmonella enteritidis cell sheath. The vaccine has shown itself to be efficacious in mice infected with this illness and is currently being employed on experimental farms of Hipra laboratories in Gerona, a company involved in the control of pathogens in birds.



Low efficacy of vaccines applied

Farmyard fowl and their derivatives are recognised as the most important source of infection of Salmonella enteritidis in humans. Both the World Health organisation (WHO) and the European Union have laid down guidelines in order to erradicate the infection in fowl, the benefits of this for humans being evident. It is generally accepted that the most practical measure is vaccination, as the easiest to apply and the most economic but, to date, all thos applied have proved to have low efficacy.

In Spain, Salmonella enteritidis is the bacteria that causes 85% of food-provoked gastroenteritis. In the concrete case of Navarre, there were 343 food poisoning cases in 2003, of which 79 were grouped together in 14 outbreaks, 12 due to Salmonella.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
