GHTM Sessions 2022 CCID03 » Back to the future: Fluorescent Acid-fast-Stains for TB-diagnosis and beyond

  • From: 09/02/2022
  • To: 09/02/2022
  • Location: ZOOM | 11h00

Traditional light-microscopy of stained smears may be replaced by fluorescent stains.
The auramine-O Acid-Fast-Stain (AFS) does not stain the cell-wall (mycolic acids), but is a classical DNA/RNA stain, whereby the cell wall only protects the microorganisms from decolorization by the acid. Confirmation of this new concept opens up the possibility to use this stain in different contexts: a) Auramine-O AFS allows the simple detection of Schistosome eggs; b) Auramine-O AFS allows detection of mycobacteria in histological samples; c) newer nucleic acid-stains may increase (broaden) the application of this stain.

GHTM Sessions 2022 CCID01 » Plasmonic nanoparticles to detect single nucleotide polymorphisms (SNPs)

  • From: 12/01/2022
  • To: 12/01/2022
  • Location: ZOOM | 11h00

There is an overall increase in life expectancy associated to high costs in health care for an ageing population in the industrialised world. Consequently, there is a demand for fast, cheap and easy to use diagnostic tests that are essential in identifying patients, determining prognosis, monitoring treatment and assessing the efficacy of prevention. Here, nanotechnology has a prominent role, with special emphasis on noble metal nanoparticles. The presentation focuses on alternative nanotechnology-based test-kit for detection of single nucleotide polymorphism as the one associated with lactose intolerance. Methodology, advantages and limitations will be discussed.

GHTM Sessions 2021 VBD01 » Hybridisation and the emergence of Candida pathogens

  • From: 20/10/2021
  • To: 20/10/2021
  • Location: ZOOM | 11h00

Human fungal infections are a growing problem having the Candida genus among the main causes. This lecture is an overview of the comparative genomic analysis of Candida pathogens, focusing on hybrid lineages and their evolution, addressing i) how spread are hybrids among Candida species, ii) the processes that drive their genomes’ evolution, and iii) the role that hybridisation might have had in the emergence of C. albicans, the major Candida pathogen.
