Seven emblematic leonardo da vinci’s drawings were investigated through third generation sequencing technology (nanopore). In addition, sem analyses were carried out to acquire photographic documentation and to infer the nature of the micro-objects removed from the surface of the drawings. The nanopore generated microbiomes can be used as a “bio-archive” of the drawings, offering a kind.

Aspergillus is the genus name for a group (over 185 species) of filamentous fungi or common molds, most of which occur in an asexual state, and reproduce by producing conidia (asexual spores or conidiophores) that can spread into many different environments, germinate, and then grow.

The first population-based incidence estimates for invasive aspergillosis were obtained from laboratory surveillance conducted in the san francisco bay area during 1992-1993 and suggested a yearly rate of 1 to 2 cases of aspergillosis per 100,000 population. 5 however, the epidemiology of invasive aspergillus infections has likely shifted since.

Aspergillosis is an infection caused by a type of mold (fungus). The illnesses resulting from aspergillosis infection usually affect the respiratory system, but their signs and severity vary greatly. The mold that triggers the illnesses, aspergillus, is everywhere — indoors and outdoors. Most strains of this mold are harmless, but a few can cause serious illnesses when people with weakened immune systems, underlying lung disease or asthma inhale their fungal spores.
Aspergillus niger is a common mold found all over the world, commonly in decaying organic matter or decaying food products. You can recognize aspergillus niger as a common black mold in moist surfaces, and in organic matter. Aspergillus niger can cause diseases in humans when its spores are inhaled and your immune system is compromised and weak.
Fungal polyketides constitute a large family of secondary metabolites endowed with a high degree of structural diversity and various biological activities. 1 these compounds include toxins such as aflatoxin b1 produced by aspergillus species, psychoactive compounds such as xenovulene, and pharmaceuticals such as the cholesterol-lowering drug lovastatin. 2 we have previously reported aspergiolide a (1), a novel cytotoxic anthraquinone derivative with a naphtho[1,2,3-de]chromene-2,7-dione.

Aspergillosis is the most common cause of fungal infection among stem cell and solid organ transplant recipients, resulting in high mortality if untreated. Patients with weakened immune system and lung diseases are at higher risk of developing severe outcomes. Early detection and quantification of aspergillus with molecular methods is crucial to isolate infected patients and provide an appropriate treatment.

Aspergillus glaucus is a filamentous fungus which is known to have a wide environmental distribution due to its physiological hardiness under more extreme conditions.

The negative criterions were the absence of fungus on histopathology and the difficulty to evaluate the drug effect.
