27. Interleukin-17A in Egyptian leprosy patients: a clinical, genetic, and biochemical study
Abstract Background: Leprosy represents a long-term communicable disease resulting from Mycobacterium leprae infection. IL-17A is one of the pro-inflammatory cytokines that protects humans against many fungal and bacterial pathogens. Objective: To investigate IL-17A (rs2275913) gene polymorphism and its circulating level in leprosy patients, and to correla

28. Design, Synthesis and Antitubercular Activity of 2-(Benzylthio)-1H-benzo[d]imidazoles
Using molecular simplification and molecular hybridization approaches, a series of 2-(benzylthio)-1H-benzo[d]imidazoles was synthesized and evaluated as in vitro inhibitors of Mycobacterium tuberculosis (M. tuberculosis) growth. Compounds 6p and 6z were considered the lead compounds from this series of molecules, with minimal inhibitory concentration (MIC) v

30. Gummatous cutaneous tuberculosis associated with the use of infliximab for Crohn's disease,
Abstract As the treatment of infectious and parasitic diseases improved, the prevalence of these conditions declined. However, with the expansion of the use of immunobiologicals, opportunistic infections have emerged, especially under atypical presentations. The present study reports the case of a patient treated with infliximab for Crohn's disease, who pres

31. SYNTHESIS, CHARACTERIZATION, DFT MODELING AND IN VITRO ANTIMYCOBACTERIAL ACTIVITY ASSAYS OF A SILVER(I)-ISONIAZID COMPLEX
In the present work, a silver(I) complex with the antimycobacterial drug isoniazid (inh) is described. Elemental and thermogravimetric analyses confirmed a 1:1 metal:ligand ratio for the silver-isoniazid (Ag-inh) complex with molecular composition AgC6H7N3O·NO3. Infrared (IR) analysis suggests a bidentate coordination of isoniazid to silver by the nitrogen

32. Diagnosis of cutaneous tuberculosis (lymph node scrofuloderma) using the Xpert MTB/RIF® method,
Abstract Cutaneous tuberculosis is a rare infection that is difficult to diagnose, because it shows less sensitivity and specificity in classic complementary exams when compared with the pulmonary form. The Xpert MTB/RIF® method offers an early diagnosis that identifies the DNA of Mycobacterium tuberculosis and the main mutations that give the bacterium res

33. Case for diagnosis. Erythematous and infiltrated plaques in the infrahyoid region,
Abstract Leprosy is a chronic infectious disease caused by Mycobacterium leprae and, depending on the host immune status, presents different clinical forms. This report describes the case of a 46-year-old man who had hypoesthetic lesions in the infrahyoid region for 30 days. The bacilloscopy was negative. The anatomopathological examination showed alteration

34. Diversidade de bactérias cultiváveis associadas a raízes de bromélias de afloramentos ferruginosos do Brasil central
Resumo Estudos sobre a diversidade bacteriana associada a plantas silvestres são raros, especialmente naqueles que crescem em associação com bromélias. No presente estudo, isolamos e identificamos bactérias epífitas e endofíticas das raízes das bromélias Dyckia excelsa, D. leptostachya e Deuterocohnia meziana ocorrentes nas “cangas” no Pantanal

35. Isolamento e tipificação genética de Mycobacterium bovis em lesões sugestivas de tuberculose em bovinos abatidos no estado do Ceará
RESUMO: A tuberculose bovina (TB) é uma zoonose causada pelo Mycobacterium bovis, o qual induz ao desenvolvimento de lesões nodulares e granulomatosas em vários tecidos do animal. O reconhecimento dessas lesões macroscópicas sugestivas durante a inspeção sanitária post mortem em matadouros fornece um diagnóstico presuntivo, sendo necessário a utili

36. Características diagnósticas do Xpert MTB/RIF para o diagnóstico de meningite tuberculosa e resistência à rifampicina no Sul do Brasil
RESUMO Introdução: O diagnóstico da meningite tuberculosa (TBM) é desafiador. Ferramentas de diagnóstico molecular são necessárias para esse diagnóstico, particularmente em países de baixa e média renda. Objetivos: Calcular as características diagnósticas do Xpert MTB/RIF para a detecção de Mycobacterium tuberculosis no líquido cefalorraquid
