Searching novel methodological approaches for the solution of problems, the objective of this work consisted on showing the results of the interdisciplinary work of the professors staff in medical Microbiology and Parasitology in that sense, based on the creation of the following didactic materials: Manual of immune response to the biological agents for medicine students, Skill system for the improvement of the subject and Didactic Guide of biological agents which attack the human being, among others. The board of professors established a new relation between students and teaching staff, derived from deep changes in the teaching method to complete the interdisciplinary demand in the academic training of students and to contribute to the integration of the subject.

El artículo examina la respuesta del hospedador en cuanto a la salud periodontal. Se menciona la inflamación y la destrucción de tejidos periodontales como resultados de la respuesta de un hospedador a la biopelícula microbiana. Se analiza las varias características del hospedador que pueden contribuir a la prevención de la periodontitis, como las células protectoras, los anticuerpos y la protección a través de la barrera epitelial.

El artículo discute la función de las bacterias en cuanto a la enfermedad de los tejidos periodontales. Las enfermedades periodontales son compuestas de unas inflamaciones aberrantes que pueden resultar en la pérdida de los dientes. Científicos han estudiado los beneficios en cuanto a la genómica humana para descifrar los polimorfismos genéticos que pueden causar la enfermedad. El artículo explora como estas bacterias relacionan con el hospedador.

We hereby present the results from a first approach to the knowledge involved in practices and beliefs related with the presence of parasites in the human body in two Guarani Mbyá communities in the province of Misiones. Aborigins' view about the subject was aroused by a series of workshops organized during interdisciplinary research meetings about enteroparasitosis in the region. Morphological criteria -color and size- are vital for characterizing parasites. These derive from feces observation. The degree of pathogenicity and virulence -and, therefore, therapeutics, should be associated to both parameters. Individual / environment duality, as well as functional criteria, make a difference between the natural and pathological presence of parasites in the human organism. In the first case, Mbya ethnophysiology states that "tacho" normally dwell in the human digestive tract and they are considered an integral component of the normal physiology of digestion. The environment is vital for the appearance of pathogenic entities, either activating inner parasites or allowing external parasites to become incorporated into the organism. According to this view, a non pathogenic state would be associated to a supposed state of balance and harmony in the relationship between these communities and the environment, which would be expressed in the observance of ancient cultural patterns, while the pathogenic state is associated to transgression of these patterns and the incorporation of new ways of life.
