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.

Drones can be used to transport laboratory samples in remote areas, but limited evidence exists on whether that transport affects the samples’ results. Given its potential, the Ministry of Health and the National Institute of Health of Mozambique partnered with VillageReach NGO to generate such data and 300 respiratory samples were transported by two drones, departing from, and returning to the «INS TB Reference Laboratory» in Marracuene district. The samples’ analysis concluded that their quality had not changed by flight, being comparable to land transport.

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.
