3R-Project 99-05

The NEMO network (Non-mammalian Experimental Models for the study of bacterial infections)

Coordinator of the network:
Pierre Cosson
Centre Médical Universitaire, Département de Physiologie Cellulaire et Métabolisme, 1 rue Michel Servet, 1211 Genève, Suisse
pierre.cosson@medecine.unige.ch

Keywords: bacteria; drosophila; protozoa: amoeba; infectious diseases; reduction; replacement; infectiosity

Duration: 4 years Project Completion: 2010

Background and Aim
To test the ability of a bacteria to cause a disease it is usually necessary to infect a mammalian host and allow the disease to progress. These experiments inflict significant suffering to the animals. Our general aim is to stimulate the emergence of a community of scientists using alternative non-mammalian hosts for the study of bacterial infections. Our common belief is that many experiments currently carried out using mammalian hosts could be advantageously replaced by the use of alternative non-mammalian hosts.

The NEMO network of laboratories was created in February 2005, initially as an informal gathering of research groups involved in similar subjects. Our specific goals are:

1-To organize an annual meeting on the theme of Non-mammalian hosts for the study of bacterial infections, in order to stimulate exchanges among research groups.

2-To strengthen our research in this field through a series of collaborative projects, for which we hope to find financial support.

3-To publicize the use of alternative non-mammalian hosts in the scientific community.
