Mass screening for fever: A comparison of three infrared thermal dectection systems and selfreported fever

Abstract

AbstractsCalmette and Guerin in animal model and influence in the protection subsequent BCG vaccination. The aim of this study was the isolation and identification of nontuberculous mycobacteria in: drinking water distribution systems in the Mexico City Metropolitan zone.Methods: Water samples were decontaminated by NaOH/SDS and cultured onto Lowenstein Jensen to 37 • C/ 30 days. Different colonies were identified by PCR-PRA 65 kDa gen, sequencing and phylogenetic inference.Results: We isolated NTM in both water sources. The most frequently occurring isolates in potable water supply system were M. nonchromogenicum, M. arupense, M. peregrinum and M. gordonae. Eleven species were isolated in wastewater and one Mycobacterium spp.Conclusion: It is important to know the geographic distribution of nontuberculous mycobacteria presence in drinking and wastewater because represent a risk for the population health.
