Uso do spoligotyping para genotipagem de Mycobacterium tuberculosis obtidos a partir de lâminas coradas pela técnica de ziehl-neelsen pertencentes a pacientes com tuberculose pulmonar residentes nos municípios paraenses de Belém e Ananindeua, Pará, Brasil. 2010. 136 f. Dissertação (Mestrado) - Universidade Federal do Pará, Núcleo de Medicina Tropical, Programa de Pós-Graduação em Doenças Tropicais, Belém, 2010.https://repositorio.ufpa.br/handle/2011/6289Tuberculosis (TB) is a major public health problem, closely linked to socioeconomic factors, and its main causative agent Mycobacterium tuberculosis. The Spoligotyping is based on PCR-reverse hybridization that permit identification and differentiation of M. tuberculosis Complex members directly from clinical samples, as samples from Ziehl-Neelsen stained slides (ZN), avoiding problems associated with slow growth of these microorganisms, thus becoming an important tool for the monitoring of strains in different epidemiological settings, being able to reveal the biogeographical character of these. The ability to characterize genetic, demographic and geographically these microorganisms can contribute both to understanding how the disease is transmitted and the implementation of actions to its control and combat. Thus, we performed a retrospective study that evaluated the samples obtained from ZN stained slides, made by public heath laboratories from Belém and Ananindeua between October 2007 and March 2008. Most (61.3%) of 163 cases included in the study belonged to the males and 68.0% of cases were between 20 and 49 years with a mean age of 38 years. Application of Spoligotyping in this kind of samples showed good performance, with 146 (89.6%) hybridization patterns of complete and consistent with each other after the duplicates. Of these, 142 were considered for comparison with the international database of Spoligotypes (SpolDB4), of which 67 were observed different spoligotype or genotypes, including 95 (67%) cases were shared by two to 20 samples and 47 (33%) with unique patterns. Forty-eight (71.6%) genotypes were known and 19 (28.4%) have not been reported in SpolDB4. LAM and T families were more frequent, concentrating 56 (39.4%) and 35 (24.6%) cases, respectively, and Haarlem, and EAI families comprised 12 (8.45%) samples each. Spatial localization of cases allowed to visualize the distribution of spoligotypes in the cities studied, revealing some groups with the same genotype, proving to be useful to guide and assist future investigations.porAcesso AbertoDoenças infecciosasTuberculoseMycobacterium tuberculosisBiologia molecularAnanindeua - PABelém - PAPará - EstadoAmazônia brasileiraUso do spoligotyping para genotipagem de Mycobacterium tuberculosis obtidos a partir de lâminas coradas pela técnica de ziehl-neelsen pertencentes a pacientes com tuberculose pulmonar residentes nos municípios paraenses de Belém e Ananindeua, Pará, BrasilDissertaçãoCNPQ::CIENCIAS DA SAUDE::SAUDE COLETIVA::SAUDE PUBLICACNPQ::CIENCIAS DA SAUDE::MEDICINA::CLINICA MEDICA::DOENCAS INFECCIOSAS E PARASITARIAS
