Article Synopsis
- TNT is a toxic explosive that contaminates the environment throughout its lifecycle, prompting the need for effective remediation strategies.
- This study presents the use of laccases from the fungus Pycnoporus sanguineus CS43 to biotransform TNT, achieving conversion rates of 80% and 87% under different oxygen conditions.
- The research highlights the potential of using laccases as a sustainable method for addressing TNT contamination, producing various harmless byproducts confirmed through advanced chromatography techniques.
Mycobacteria are microorganisms distributed in the environment worldwide, and some of them, such as Mycobacterium tuberculosis or M. leprae, are pathogenic. The hydrophobic mycobacterial cell envelope has low permeation and bacteria need to export products across their structure.

Our research group identified a low expression of lipF gene in Mycobacterium tuberculosis clinical isolates with drug resistance. The aim of this work was to evaluate the effect of lipase F (LipF) expression on mycobacterial drug resistance.
View Article and Find Full Text PDFTuberculosis drug resistance (DR) is a global problem that is not fully elucidated. Previously, overexpression of and genes was reported in a multidrug-resistant (MDR) isolate compared with a reference H37Rv strain. To evaluate the roles of and in DR, analysis of their regulatory and coding sequences in sensitive and resistant strains was performed, and the expression levels of their transcriptional regulators IdeR, Zur, and MntR were evaluated.
View Article and Find Full Text PDFBackground: Despite the uncontrolled distribution of the Influenza A virus through wild birds, the detection of canine influenza virus and equine influenza virus in Mexico was absent until now. Recently, outbreaks of equine and canine influenza have been reported around the world; the virus spreads quickly among animals and there is potential for zoonotic transmission.
Methods: Amplification of the Influenza A virus matrix gene from necropsies, nasal and conjunctival swabs from trash service horses and pets/stray dogs was performed through RT-PCR.
