Resumo: | Tuberculosis (TB) control is linked to the availability of qualified methods for microbiological diagnostics; however, microscopy with limited sensitivity is the only method available in many locations. The objective of this study was to evaluate the introduction of culture, drug susceptibility testing (DST), and genotyping in the routine of a Municipal Program of Tuberculosis Control. Methods: Direct microscopy of sputum and culture in Ogawa-Kudoh were performed on 1,636 samples from 787 patients. DST of positive cultures was performed by resazurin microtiter assay and genotyping by mycobacterial interspersed repetitive units–variable number tandem repeat. Results: A total 91 patients with TB were identified. The culture increased case detection by 32% compared with the microscopy; acquired resistance was 3.3% and the genotyping showed high genetic diversity. Conclusions: Ogawa-Kudoh contributed significantly to the increase in case detection and is suitable for implementation in poor-resource locations. The acquired resistance rate was lower than that reported in a recent Brazilian survey. The high genetic diversity is possibly related to the high TB prevalence in the population, as well as to early detection and suitable treatment of patients. The interaction between research and health care is important for reorienting the practice, transferring technology, and improving TB control. |

Métodos:A baciloscopia direta do escarro e cultura em Ogawa-Kudoh foram realizadas em 1.636 amostras de 787 pacientes. O TSA das culturas positivas foi realizado pelo método de microdiluição e a genotipagem por Mycobacterial Interspersed Repetitive Units – Variable Number Tandem Repeat (MIRU-VNTR). Resultados: Foram identificados 91 pacientes com TB, com a cultura aumentando em 32% a detecção de casos em comparação com a microscopia; a resistência adquirida foi de 3,3% e a genotipagem mostrou alta diversidade genética. Conclusões: O cultivo em Ogawa-Kudoh contribuiu significativamente para o aumento na detecção de casos e é adequado para ser implementado em locais com poucos recursos. A taxa de resistência adquirida foi menor do que a relatada em recente inquérito nacional. A alta diversidade genética está possivelmente relacionada à alevada prevalência de TB na população, detecção precoce e tratamento adequado dos pacientes.A interação entre a pesquisa e serviço de saúde pública é importante para reorientar a prática, transferir tecnologia e melhorar o controle da TB.2013-10-12T02:40:26Z2013-10-12T02:40:26Z2012info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfVALENÇA, Mariana Soares et al.
