[Role of local immunity in invasive pulmonary aspergillosis].

A LEADING CAUSE OF MORTALITY: Inhalation of fungal spores may cause infection and/or inflammation, which is dependent on the nature of the fungus as well as the individual's immune status. Aspergillus fumigatus is responsible for a dramatic pathology, invasive aspergillosis (IA). IA has become a leading cause of death, mainly among bone marrow transplantation or solid-organ recipients, but also among AIDS patients. IMMUNE RESPONSE: The diversity of immune failure suggests that many lines of immunity are implicated in the A. fumigatus elimination process. Non specific immunity plays a major role in the defence against A. fumigatus, including three major lines: anatomical barriers, humoral components, phagocytic cells. But acquired immunity plays a role with different T-cell subsets and their associated cytokines. FUNGUS-HOST RELATIONSHIPS: The relationship between the fungus and its host is complex and could be again study to improve the prevention and the treatment of IA. The aim of this review is a synthesis of the knowledge about the immunity response against Aspergillus fumigatus in IA.

[Emerging parasitosis ans mycosis: risk and threats for the new millenium].

For multiple reasons, the emergent infectious risks do not stop increasing these last twenty years. The climatic modifications and the human interventions modifying the biotope as well as the rapid spreading of resistant strains to treatments, generate re-emergence or emergence, all the more dramatic as the means of fight are reduced. These emergent or re-emergent diseases are extremely worrisome as their diagnosis and their prevention are often difficult. The important infesting power of parasites and the particularly effective capacities of adaptation of these eucaryotes contributed to the public health problems. Anthropozoonoses and zoonoses constitute a permanent risk the control of which is imaginary. The new pathogenic agents, the unusual clinical demonstrations in the context of deficiency of the host immune functions imply attentiveness and a permanent up to date of the knowledge of the biologist and of the different professionals of health. The risks with which are confronted the humanity during this century underline the necessity of determining mechanisms involved in the pathogenesis. The determination of the specific and vital biologic processes for the microorganism, could allow to define the most appropriated targets and the most effective and original means of fight.
