[Viral genotypes in different infective processes].

This lecture includes three sections. Firstly, the concepts of genotype, subtype and quasi-specie are described. The appearance of virus is correlated with the evolution of the medical picture, and their resistance to antiviral agents. Secondly, the most modern genetical and molecular biology techniques, including DNA sequencing are studied. Thirdly, some examples of the investigation lines carried out at the Microbiology Department of the Granada Medicine School are explained, especially regarding to papillomavirus, hepatitis C virus, hepatitis G virus, virus associated to transfusions (TTV) and human immunodeficiency. The great transcendence that the genetical variability has to establish pathogeny and therapy control is emphasized.

[A comparative study of western blot interpretation criteria for Lyme disease serological diagnosis in our environment].

We have studied the WB reliability for the Lyme disease (LD) serological diagnosis. Twenty five samples (20 sera and 5 CSF) from 5 patients with LD, according to CDC criteria were analyzed. The syphilis was excluded in every patient. Borrelia burgdorferi antibodies were assessed by an indirect ELISA (IgG + IgM, B31 strain). Intrathecal antibodies in CSF were studied in patients with neurological diseases. Positive samples by ELISA were reanalyzed by WB according to the manufacturer, Tilton and Dressler criteria and presence either 93, 39, 34 or 23 kDa band for IgG. Four patients were controlled and one of them (25%) became negative the antibodies (serorreversion). Three of them, who had neurological symptoms, displayed intrathecal antibodies. WB sensibility for LD according to the manufacturer, Tilton, Dressler and any of the four IgG bands was 26.31%, 42.1%, 21% and 84% for IgG and 52.6%, 47.3% and 42.1% for IgM respectively. Tilton and Dressler criteria may not be as sensible as 93, 39, 34 or 23 kDa IgG bands for the diagnosis of LD in our environment.
