ABSTRACT
Growing budget restrictions in many countries have meant that official Veterinary Services cannot assume responsibility for any new activities. The natural reaction is to turn to private veterinary services to provide the support needed to strengthen the control and surveillance of priority diseases and thereby support the development of the livestock sector and the establishment of safe international trade. In this context, official Veterinary Services must work together with private veterinarians, delegating various technical animal health activities, so that they may focus their efforts on those tasks that cannot be delegated: standardisation, control, auditing, general system co-ordination, epidemiological surveillance, etc., as well as organising veterinary policy in order to make best use of budget resources. For these relations to be efficient, a dynamic, two-way epidemiological information mechanism must be created, whereby private veterinarians periodically keep governments informed, on the basis of an agreed methodology. Moreover, the official Veterinary Services must systematically transmit information on List A and B diseases of the OIE (World organisation for animal health), and perform detailed analyses of epidemiologically significant events. The article proposes the establishment of relations between public and private veterinary services as a way in which to provide the livestock sector with the health and hygiene conditions that are necessary for effective disease control, which in turn provides greater security for international trade and increased consumer protection.

La interacción hospedero-parásito juega un papel importante en la evolución de las enfermedades infecciosas. En este articulo se analiza esta interacción desde el punto de vista del hospedero, es decir de la respuesta inmune incluyendo los conceptos de la respuesta T1 y T2 frente al microorganismo. En infecciones con lepra cada vez es más claro el papel de la respuesta T1/T2 y su relación con la evolución de la enfermedad, pero falta por esclarecer como un individuo responde con una u otra lo que se traduce en curación ó enfermedad. En las infecciones por Herpes simplex aunque no es tan claro el papel de la respuesta T1/T2 si lo es el de algunas citocinas tanto en la primoinfección, latencia y reactivación. Finalmente en las infecciones por Criptococcus neoformans, aunque las características propias del microorganismo se relacionan con la evolución de la infección, la respuesta inmune con perfil T1 se asocia con el control de la infección
