Candidemia is the predominant form of invasive candidiasis and the most frequently occurring serious fungal infection in critically ill patients in Intensive Care Units (ICU). Studies carried out in Latin America reveal a higher incidence of candidemia and higher mortality rates when compared to North America or Europe. This highlights the need to develop guidelines for correctly diagnosing and treating candidemia in critically ill patients in the ICU.

Introduction: Amphotericin B lipid complex (ABLC) is an effective antifungal agent for treating invasive fungal infections (IFIs) even though its formulation is associated with potential adverse events, including those related to its infusion. This study aimed to analyze the incidence of acute infusion-related side effects (IRSE) associated with ABLC and their relationship with the profile of patients with oncohematological disease admitted in Brazilian reference tertiary hospitals.

Methods: This is an observational retrospective study that included clinical records of patients hospitalized, in a period of 6 years, diagnosed with probable or proved IFI and treated with at least two doses of ABLC.

Chromoblastomycosis, an implantation mycosis, is a neglected tropical disease that causes decreased quality of life, stigma, and disability. The global burden of disease is unknown and data on disease epidemiology and outcomes are severely limited by a lack of access to needed diagnostic tools and therapeutics. The World Health Organization outlined targets for chromoblastomycosis in the Road Map for Neglected Tropical Diseases 2021-2030, but little progress has been made in initiating and implementing an effective control program globally.

Previously considered saprobe and non-pathogenic, the fungus Papiliotrema laurentii (formerly known as Cryptococcus laurentii), is rarely associated with human infection. Nevertheless, there has been an increase in reported infections by non-neoformans cryptococci. After a literature search on the Cochrane Library, LILACS, SciELO, MEDLINE, PubMed, and PMC (PubMed Central) databases, we conclude that this is the first case report of fungemia and probable meningitis caused by Papiliotrema laurentii in a previously immunocompetent host with associated COVID-19.

Fungal skin infections are distributed worldwide and can be associated with economic and social traits. The immune response related to skin cells is complex and its understanding is essential to the comprehension of each cell's role and the discovery of treatment alternatives. The first studies of trained immunity (TI) described the ability of monocytes, macrophages and natural killer (NK) cells to develop a memory-like response.

is an emerging fungal pathogen causing cat-transmitted sporotrichosis, an epi-zoonosis affecting humans, cats and dogs in Brazil and now spreading to neighboring South American countries. Here, we report the first two autochthonous cases of cat-transmitted sporotrichosis in Paraguay. The first case was a four-year-old male cat showing several ulcerative lesions, nasal deformity and respiratory symptoms.

Dermatophytosis is a superficial cutaneous infection, most commonly caused by fungal species such as Microsporum canis, Nannizzia gypsea (Microsporum gypseum), and Trichophyton mentagrophytes in dogs and cats. The zoonotic potential of these species is concerning, as companion animals are increasingly close to their owners. Therefore, the objectives of the study were to evaluate the current prevalence of Nannizzia-causing canine and feline dermatophytosis in Curitiba and Metropolitan Region, as well as perform phenotypic and phylogenetic characterizations of these isolates.

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
  • Zoonotic outbreaks of sporotrichosis in Brazil, particularly cat-transmitted sporotrichosis (CTS) from the fungus Sporothrix brasiliensis, are on the rise, with a significant increase in cases observed between 2011 and 2022 in Curitiba.
  • In a review of 216 cases, the incidence rose dramatically from 0.3 to 21.4 cases per 100,000 outpatient visits over the decade, with 58% of cases occurring from 2019 to 2021.
  • The most common form of sporotrichosis was lymphocutaneous, accounting for 63% of cases, highlighting the need for greater public awareness and preventive measures against transmission.

Candidemia remains a major public health challenge due to its high mortality rates, especially in developing countries. Monitoring epidemiological trends may provide insights for better clinical outcomes. This study aimed to describe trends in the epidemiology, therapeutic practices, and mortality in candidemia through a retrospective comparative analysis between two surveillance cohorts of all candidemic adults at eleven tertiary hospitals in Brazil, from 2010-2011 (Period I) versus 2017-2018 (Period II).

Article Synopsis
  • Sporotrichosis is an infection caused by the fungus Sporothrix, primarily affecting skin, subcutaneous tissues, and lymphatic vessels, with S. brasiliensis being especially virulent in Latin America.
  • A study analyzing 89 isolates from humans and cats in Southern Brazil found 81 S. brasiliensis and 7 S. schenckii, with no significant differences in antifungal susceptibility between the two host species.
  • Antifungal testing showed that the novel drug olorofim was highly effective against all tested isolates, while only one human isolate displayed resistance to itraconazole and posaconazole, with no specific genetic mutations linked to this resistance identified.
