“…Others develop severe fungal infections on their skin that can be detrimental because the infections produce scabs, which then fall off, leaving bare skin that is susceptible to ectoparasites like ticks and mosquitos (Fig. 9C; Xavier et al, 2008); anecdotally, fungal infections generally correlate with sick sloths (S. Trull, unpublished data). It is unclear whether these infections derive from fungi that are already part of the sloth fur microbiome and/or whether they are a primary cause for sloths getting sick.…”

Sloths are unusual mobile ecosystems, containing a high diversity of epibionts living and growing in their fur as they climb slowly through the canopies of tropical forests. These epibionts include poorly studied algae, arthropods, fungi, and bacteria, making sloths likely reservoirs of unexplored biodiversity. This review aims to identify gaps and eliminate misconceptions in our knowledge of sloths and their epibionts, and to identify key questions to stimulate future research into the functions and roles of sloths within a broader ecological and evolutionary context. This review also seeks to position the sloth fur ecosystem as a model for addressing fundamental questions in metacommunity and movement ecology. The conceptual and evidence-based foundation of this review aims to serve as a guide for future hypothesis-driven research into sloths, their microbiota, sloth health and conservation, and the coevolution of symbioses in general.

“…M. gypseum is a geophilic dermatophyte, as such it generally inhabits the soil, where it decomposes into keratinized debris. M. canis, on the other hand, being zoophilic, has adapted to animals and is only rarely found in the soil [12]. This pathology leads to health problems that are usually caused by topical drugs and/or dermo-cosmetic applications.…”

Machine Learning Data Augmentation as a Tool to Enhance Quantitative Composition–Activity Relationships of Complex Mixtures. A New Application to Dissect the Role of Main Chemical Components in Bioactive Essential Oils

et al. 2021

Scientific investigation on essential oils composition and the related biological profile are continuously growing. Nevertheless, only a few studies have been performed on the relationships between chemical composition and biological data. Herein, the investigation of 61 assayed essential oils is reported focusing on their inhibition activity against Microsporum spp including development of machine learning models with the aim of highlining the possible chemical components mainly related to the inhibitory potency. The application of machine learning and deep learning techniques for predictive and descriptive purposes have been applied successfully to many fields. Quantitative composition–activity relationships machine learning-based models were developed for the 61 essential oils tested as Microsporum spp growth modulators. The models were built with in-house python scripts implementing data augmentation with the purpose of having a smoother flow between essential oils’ chemical compositions and biological data. High statistical coefficient values (Accuracy, Matthews correlation coefficient and F1 score) were obtained and model inspection permitted to detect possible specific roles related to some components of essential oils’ constituents. Robust machine learning models are far more useful tools to reveal data augmentation in comparison with raw data derived models. To the best of the authors knowledge this is the first report using data augmentation to highlight the role of complex mixture components, in particular a first application of these data will be for the development of ingredients in the dermo-cosmetic field investigating microbial species considering the urge for the use of natural preserving and acting antimicrobial agents.

“…Macroconidia are multiseptate, with thin or thick echinulate cell wall, spindle shaped and may be numerous or scarce [25] [27]. Causing by Microsporum is known as microsporosis, usually produces a single inflammatory skin or scalp lesion [31].…”

Earth has been documented as a natural territory for fungi which cover individual kingdom with evolution. In subsequently vertebrates developed keratin which was a part of life as a structural aspect. Few moulds have skilled to digest keratin and crop up from soil and wastewater habitats. They take part as a keratinolytic agent in the purification of α-keratins with an incidence of disulphide and hydrogen bonds which are improperly biodegradable. The best moulds genera to decay of keratin are Microsporum, Trichophyton and Epidermophyton. The presences of these genera are open health issues in developing countries where they cause the mortal mycotic contagion. The reason behind this is perceived to be the poor hygienic environment and socioeconomic behaviour among people. The present review is a compilation of updated information concerning the nature of these keratinolytic moulds and abundances of most contributed developing countries including India.
