Apendicitis por Paracoccidioides brasiliensis.

Revista Médica Herediana, 2012
La paracoccidioidomicosis es la micosis más prevalente en Sudamérica. La forma aguda afecta el sistema fagocítico mononuclear de niños y personas inmunocomprometidas. El compromiso gastrointestinal es frecuente y su patogenia implica diseminación hematógena y linfática. La linfadenomegalia abdominal causa obstrucción intestinal y abdomen agudo. En este

Biomolecular Corona Remodelling of Aspergillus fumigatus Extracellular Vesicles Shapes Immune Recognition and Macrophage Activation Programs

Journal of Extracellular Biology, Volume 5, Issue 5, May 2026.
ABSTRACT Extracellular vesicles (EVs) released by Aspergillus fumigatus play key roles in fungal–host communication. Similar to synthetic nanoparticles, fungal EVs acquire a biomolecular corona composed of a tightly bound “hard” corona layer of fungal proteins and a dynamic “soft” layer of host‐derived molecules adsorbed upon contact with biological ...

Clinical and Eco-Epidemiological Aspects of a Novel Hyperendemic Area of Paracoccidioidomycosis in the Tocantins-Araguaia Basin (Northern Brazil), Caused by Paracoccidioides sp.

Journal of Fungi, 2022
Paracoccidioidomycosis (PCM) is the most prevalent systemic mycosis in Brazil. The disease is caused by dimorphic fungi nested within the Paracoccidioides genus.

The Role of Chlamydospores of Paracoccidioides brasiliensis

Nippon Ishinkin Gakkai Zasshi, 2003
The role of chlamydospores in the conversion process from a mycelial-to-yeast form using the slide culture method was studied. Three clinical isolates and two other isolates from armadillo, belonging to the fungal species Paracoccidioides brasiliensis, were cultured on Sabouraud dextrose agar (SDA), potato dextrose agar (PDA) and brain heart infusion ...

The Hemoprotein Hhy1 Promotes Heme‐Dependent Catalase Activity of Ctt1

Molecular Microbiology, Volume 125, Issue 5, Page 389-411, May 2026.
A Schizosaccharomyces pombe strain deficient in heme (hem1Δ) and siderophore (Fc) biosynthesis, as well as high‐affinity iron (Fe) uptake (blue), was used to uncover the hemoprotein Hhy1 that promotes the heme‐dependent activity of the catalase Ctt1. In contrast, hhy1Δ cells exhibit reduced Ctt1 activity and increased sensitivity to oxidative stress ...

Evaluation of commercial immunodiffusion reagents for detecting serum anti-Paracoccidioides antibodies [PDF]

Revista da Sociedade Brasileira de Medicina Tropical
Background: Accurate diagnosis of paracoccidioidomycosis is crucial for improving patient outcomes. Paracoccidioides antibody detection by double immunodiffusion (DID) is a convenient diagnostic tool, but testing performance can vary based on certain ...

Transcriptional and proteomic responses to carbon starvation in Paracoccidioides. [PDF]

PLoS Neglected Tropical Diseases, 2014
BACKGROUND: The genus Paracoccidioides comprises human thermal dimorphic fungi, which cause paracoccidioidomycosis (PCM), an important mycosis in Latin America. Adaptation to environmental conditions is key to fungal survival during human host infection.

Random sequencing ofParacoccidioides brasiliensisgenes [PDF]

Medical Mycology, 2005
Paracoccidioides brasiliensis genome has been reported as having a size of about 30 Mb. By digestion of genomic DNA from strain IVICPb 73 (ATCC 32071), we have constructed a DNA library with an insert size average of 8 kb in Escherichia coli XL1 Blue.

Helminths as architects of trained tolerance: implications for human health

Clinical &Translational Immunology, Volume 15, Issue 3, 2026.
Abstract Helminths infect nearly 2 billion people worldwide and are a major cause of chronic morbidity in low‐resource regions. Unlike bacterial and viral pathogens that elicit protective memory, helminths actively remodel host immunity to enable their years‐long persistence and reinfection.

A hidden battle in the dirt: Soil amoebae interactions with Paracoccidioides spp.

PLoS Neglected Tropical Diseases, 2019
Paracoccidioides spp. are thermodimorphic fungi that cause a neglected tropical disease (paracoccidioidomycosis) that is endemic to Latin America. These fungi inhabit the soil, where they live as saprophytes with no need for a mammalian host to complete ...
