Unlabelled: Sporotrichosis is a subcutaneous mycosis of global distribution, capable of affecting both humans and animals, and caused by species of the genus spp. This study aimed to evaluate the genetic diversity and mating type distribution of clinical isolates of human sporotrichosis in Paraíba, Brazil, to better understand the population structure, epidemiology, and diversification of this pathogen, as well as to explore possible transmission routes.
Methods: A total of 36 clinical isolates were morphologically identified, and clinical and demographic data were collected.
Sporotrichosis is a subcutaneous infection caused by dimorphic species embedded in the clinical clade. Fungi have virulence factors, such as biofilm and melanin production, which contribute to their survival and are related to the increase in the number of cases of therapeutic failure, making it necessary to search for new options. Proton pump inhibitors (PPIs) have already been shown to inhibit the growth and melanogenesis of other fungi.

A wide range of symptoms is related to the disease; however, lungs and skin are the sites predominantly affected. The disease is mostly seen in people living in rural areas in Latin America.

The lymphocutaneous manifestation, historically associated with occupational activities and sapronotic transmission, has recently been observed to also occur through animal contact, particularly notable in Brazil. We describe a rare case of lymphocutaneous sporotrichosis with simultaneous pulmonary complications resulting from the scratching of a southern three-banded armadillo, Tolypeutes matacus, primarily inhabiting the arid forests of South America's central region.

The laboratorial diagnosis of PCM relies on observing pathognomonic structures such as the "steering wheel" or "Mickey Mouse" shape in the direct mycological examination, fresh biopsied tissue in 10% KOH, histopathological analysis, and/or the isolation of the fungus in culture. However, these procedures are time-consuming and do not allow for the speciation of due to overlapping morphologies.

The mycosis is caused after a traumatic inoculation of fungal propagules into the host and may follow an animal or environmental transmission route. The main culprits of sporotrichosis are thermodimorphic Sporothrix species embedded in a clinical clade, including S.

This research aimed to determine the clinical, epidemiological and laboratory characteristics of chromoblastomycosis in the state of Mato Grosso, Brazil.
Materials And Methods: Patients diagnosed with chromoblastomycosis treated at the Júlio Müller University Hospital, Cuiabá, Brazil, from January 2015 to December 2020, whose isolates were preserved in the Research Laboratory of the Faculty of Medicine of the Federal University of Mato Grosso.

Routine diagnoses using classical mycological approaches are unspecific due to overlapping phenotypes. As the frequency and prevalence of sporotrichosis increases worldwide, developing specific, sensitive and cost-effective diagnostic tools is essential to understand the distribution patterns, map-affected areas and promote specific public health strategies to mitigate future outbreaks.

Methods: The patient's sera with PCM were analyzed by DID test at the beginning and the end treatment. Clinical and demographic data were also collected to characterize the sample.
Sporothrix schenckii and allied species are thermodimorphic fungi widely distributed in nature which causes human and animal sporotrichosis, the most common subcutaneous mycosis globally. Sporotrichosis is acquired after a traumatic inoculation of soil or plant material contaminated with Sporothrix propagules or through bites and scratches from diseased cats. In Ascomycota, the master regulators of sex are MAT genes that lie in a single mating-type locus, in Sporothrix these are determined by two nonhomologous alleles, MAT1-1 and MAT1-2.

Sporotrichosis is a subcutaneous mycosis resulting from the traumatic implantation of pathogenic Sporothrix species. In Brazil, zoonotic transmission plays an important role in the epidemiology of the disease, involving especially cats. The objective of this study was to isolate Sporothrix spp.

Methods: This epidemiological, observational, analytical, cross-sectional study was performed to investigate the clinical and laboratory data of 44 PCM patients with a culture-proven P. lutzii infection.
Persister cells are metabolically inactive dormant cells that lie within microbial biofilms. They are phenotypic variants highly tolerant to antimicrobials and, therefore, associated with recalcitrant infections. In the present study, we investigated if and are able to produce persister cells.
