Sugarcane (Saccharum officinarum, Poaceae) is cultivated on a large scale in (sub)tropical regions such as Brazil and has considerable economic value for sugar and biofuel production. The plant is a rich substrate for endo- and epiphytic fungi. Black yeasts in the family Herpotrichiellaceae (Chaetothyriales) are colonizers of human-dominated habitats, particularly those rich in toxins and hydrocarbon pollutants, and may cause severe infections in susceptible human hosts.

Article Synopsis
- * This study involved sequencing and analyzing the whole genome of C. exuberans to identify genes related to its management of carbon and toxins, as well as its tolerance to heavy metals like lead and copper.
- * Findings showed that C. exuberans could tolerate high levels of copper (up to 2500 ppm) and lead (up to 2500 ppm) while also effectively removing these metals from its environment, indicating its potential for use in cleaning up
Chromoblastomycosis is a chronic, cutaneous or subcutaneous mycosis characterized by the presence of muriform cells in host tissue. Implantation disease is caused by melanized fungi related to black yeasts, which, in humid tropical climates, are mainly members of the genus . In endemic areas of Brazil, and are the prevalent species.

- Chromoblastomycosis is a neglected infectious disease that mainly affects rural workers through skin lesions caused by fungi from contaminated soil and plants.
- The study examined the role of social insects like ants, bees, and termites as potential habitats for the disease-causing fungi, identifying several fungal strains associated with these insects.
- Pathogenicity tests on these fungi showed that they can cause disease in animal models, revealing their ability to persist in host tissues.
Most human epidemiological and clinical studies use visual inspection of the hair and scalp to diagnose Pediculus humanus capitis , however this method has low sensitivity to diagnose active infestations (presence of nymphs and adult lice). Vacuuming the hair and scalp has been used as a diagnostic method, but there are no previous data comparing its effectiveness with visual inspection. The aim of this study was to determine the prevalence of overall infestation (nits and trophic stages), of active infestation by Pediculus humanus capitis , and to evaluate the effectiveness of vacuuming in comparison with the visual inspection.

A comparative study was carried out evaluating groups of schoolchildren with (group A) and without pediculosis (group B) to analyse the characteristics of the scalp microbiota. Samples were collected by swab using Stuart transport medium and incubate in Sabouraud dextrose agar with tetracycline to analyse the fungal microbiota and in blood agar to assess the bacterial microbiota.

The current hypothesis is that patients acquire the infection through an injury from plant material. The present study aimed to evaluate a model of infection in plant and animal hosts to understand the parameters of trans-kingdom pathogenicity.
