Background: Sporotrichosis is a fungal infection caused by species of the Sporothrix genus. Presently, the prevalence of sporotrichosis in the Americas is unknown, so this study aims to analyze the cases reported in the past 10 years. Methods: An advanced search was conducted from 2012 to 2022 in English and Spanish in PUBMED, SciELO, and Cochrane, with the terms: “sporotrichosis”, “lymphocutaneous sporotrichosis”, “fixed sporotrichosis”, “mycosis”, “Sporothrix spp.”, “Sporothrix complex”, “S. schenckii sensu stricto”, “S. schenckii sensu lato”, “S. globose”, “S. brasiliensis”, “S. luriei”. Sporotrichosis is a fungal infection caused by species of the Sporothrix genus associated with “pathogenicity” or “epidemiology”. Results: A total of 124 articles were found in the Americas, corresponding to 12,568 patients. Of these, 87.38% of cases were reported in South America, 11.62% in North America, and 1.00% in Central America and the Caribbean. Brazil, Peru, and Mexico had the highest number of cases. The most prevalent etiological agents were S. schenckii complex/Sporothrix spp. (52.91%), S. schenckii (42.38%), others (4.68%), and Not Determined (ND) (0.03%). The most frequent form of the disease was lymphocutaneous infection; however, the infection type was not determined in 5639 cases. Among the diagnostic methods, culture was the most used. Conclusions: There is a high occurrence of cases reported in the literature. South America is the region with the highest number of reports because of its environment (climate, inhalation of spores, etc.), zoonotic transmission (scratches and sneezes from contaminated animals), and possible traumatic inoculation due to outdoor activities (agriculture, gardening, and related occupations). Molecular diagnosis has not been sufficiently developed due to its high cost.

Antifungal peptides (AFPs) comprise a group of substances with a broad spectrum of activities and complex action mechanisms. They develop in nature via an evolutionary process resulting from the interactions between hosts and pathogens. The AFP database is experimentally verified and curated from research articles, patents, and public databases. In this review, we compile information about the primary databases and bioinformatics tools that have been used in the discovery of AFPs during the last 15 years. We focus on the classification and prediction of AFPs using different physicochemical properties, such as polarity, hydrophobicity, hydrophilicity, mass, acidic, basic, and isoelectric indices, and other structural properties. Another method for discovering AFPs is the implementation of a peptidomic approach and bioinformatics filtering, which gave rise to a new family of peptides that exhibit a broad spectrum of antimicrobial activity against Candida albicans with low hemolytic effects. The application of machine intelligence in the sphere of biological sciences has led to the development of automated tools. The progress made in this area has also paved the way for producing new drugs more quickly and effectively. However, we also identified that further advancements are still needed to complete the AFP libraries.

Monkeypox (Mpox) is an infectious disease caused by the Mpox virus belonging to the Orthopoxvirus genus in the Poxviridae family and has been declared by the WHO as a global health emergency owing to its rapid spread during 2022 and 2023. All patients diagnosed with Mpox who were confirmed by PCR between July 2022 and April 2023 were included in this study. In total, 405 patients in whom clade 2 was identified were included. Notably, 99% of included patients were men, with 82% of them aged 20–39 years. Furthermore, 71% were men who had sex with men, and 34% were HIV carriers. Regarding the morphology of the lesions, approximately 63% presented with papulonecrotic rash, which sometimes alternated with pustules depending on the stage they were in. All patients presented with systemic symptoms. Five patients required hospital admission, one of whom died, and presented with HIV and severe immunosuppression. Clinical findings suggest that contact during sexual intercourse is the most likely transmission mechanism and genital involvement is the most frequent clinical form. HIV was the primary comorbidity. Genital lesions were common, especially in vulnerable populations such as those who engage in high-risk sexual behaviors.
