Research ArticleOpen accessIn the abstractDesign, Synthesis, Biological Screening and Structure Activity Relationship Study of 4, 6-Dimethyl-2-(Substituted) Mercapto-3-(Substituted) Pyridines as Anti Tubercular AgentsMehul M. Patel, Mahesh T. ChhabriyaProblem statement: Tuberculosis is a leading global mortality factor which has not been effectively controlled, with 1.7 million deaths per year and 8.9 million new cases. Aerobic microbe Mycobacterium tuberculosis H37Rv (MTB) is the causative agent of tuberculosis. Although many active antitubercular agents have since been developed, drug resistance will continue to be a problem. Therefore, there is a clear … …American Journal of Infectious Diseases, Vol. 7, Issue 3 · 3 Nov 2011 · 7,430 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUnique Characteristic Features of Mycobacterium Tuberculosis in Relation to Immune SystemRajni, Laxman S. MeenaProblem statement: Tuberculosis is a leading global mortality factor which has not been effectively controlled, with 1.7 million deaths per year and 8.9 million new cases. Aerobic microbe Mycobacterium Tuberculosis H37Rv (MTB) is the causative agent of tuberculosis. Approach: It is unique among prokaryotes due to its exceptional features contributing to its survival within the hostile environment of macrophages.

Research ArticleOpen accessIn the abstractExogenous Re-infection by Multiple Exposures to Mycobacterium tuberculosis Contributes to Subsequent Development of Active TuberculosisDiane J. Ordway, Miguel Viveiros, Fernando A. Ventura et al.The majority of tuberculosis (TB) exists in the world’s poorest countries, where costly biosafety level three facilities for containment of infectious TB patients and diagnostic facilities are not affordable. Health care workers (HCWs), in countries with high burdens of tuberculosis (TB) are at risk of nosocomially acquired TB, as there are increased numbers of cases of TB on open hospital … …American Journal of Immunology, Vol. 1, Issue 1 · 31 Mar 2005 · 6,967 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMycobacterium tuberculosis Complex Mutations in Drug Resistant Clinical Isolates from Southwest MexicoMartínez-Cruz Perla Mónica, Nakamura-López Yuko, Quintero-Hernández Verónica et al.Mutations in target genes have been described in Mycobacterium tuberculosis Complex (MTBc) drug resistant isolates worldwide. In Mexico, not enough information has been reported in this concern. The aim of this study was to characterize mutations related to resistance to first line drugs in MTBc isolates from Oaxaca, Mexico. MTBc isolates were identified in clinical samples from Tuberculosis (TB) patients. … …American Journal of Infectious Diseases, Vol. 17, Issue 4 · 28 Oct 2021 · 6,667 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGenetic Diversity and Drug Resistance of Mycobacterium tuberculosis Complex Isolates and Nontuberculous Mycobacteria Identification from Presumptive Tuberculosis Cases in Oaxaca, MexicoNakamura-Lopez Yuko, Valencia-Carmona Oscar Daniel, Martinez-Cruz Perla Monica et al.Tuberculosis (TB) is a re-emerging health problem worldwide. In Mexico, information about genetic diversity and drug resistance of Mycobacterium Tuberculosis complex (MTBc) is limited. Samples from 463 Presumptive TB cases were tested for TB by smear, culture and PCR, from which 19.2% were identify as MTBc and 16% as nontuberculous mycobacteria. MTBc isolates were characterized by Large Sequence Polymorphisms (LSPs), … …American Journal of Infectious Diseases, Vol. 16, Issue 1 · 9 Feb 2020 · 7,159 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAerobic Biodegradation of Per-Treated Methyl Tert-Butyl Ether By Ozonation in an Up-Flow-Fixed-Bed ReactorM. Sadeghi, M. Arbabi, A. Nikpey, G. MardaniProblem Statement: MTBE is a common pollution of environmental and has become an issue of considerable concern in recent years. It is not readily amenable to remove MTBE by conventional techniques in water treatment. In the present study, the feasibility of the continuous aerobic biodegradation of MTBE, was evaluated in an Up- Flow Fixed Bed Reactor (UFBR). Approach: The UFBR … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,620 accessesView PDF Cite
