A steric gate prevents mutagenic dATP incorporation opposite 8‐oxo‐deoxyguanosine in mitochondrial DNA polymerases

open access: yesThe FEBS Journal, Volume 292, Issue 13, Page 3430-3448, July 2025.
Reactive oxygen species induce mutagenic DNA lesions, such as 8‐oxo‐2′‐deoxyguanosine (8‐oxodG), which acts as a template for dCMP and dAMP incorporation through its anti and syn conformations. Specific residues must regulate the fidelity of templated 8‐oxodG.

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

open access: yesPLoS 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.

The Study of Microbial Physiology Under Microoxic Conditions Is Critical but Neglected

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 3, June 2025.
Microbial physiology is mainly studied under aerobic or anaerobic/anoxic conditions, neglecting microbial behaviours in diverse microoxic conditions. The current article revisits the definition of microoxia in light of recent developments in oxygen‐sensing technology and emphasises the need to understand microbial physiology and growth behaviours of ...

The taxonomy of two uncultivated fungal mammalian pathogens is revealed through phylogeny and population genetic analyses

open access: yesScientific Reports, 2021
Ever since the uncultivated South American fungal pathogen Lacazia loboi was first described 90 years ago, its etiology and evolutionary traits have been at the center of endless controversies.

Molecular detection and identification of Paracoccidioides brasiliensis [PDF]

open access: yesJournal of Clinical Microbiology, 1997
Nearly 800 nucleotides from the 5' terminus of the 28S ribosomal gene of Paracoccidioides brasiliensis were sequenced, and a 14-base DNA probe specific for this species was identified. Hybridization results showed that the probe identified P. brasiliensis ribosomal DNA in a panel of ribosomal DNAs representing a total of 48 species of fungi.

Understanding causes of morbidity and mortality in Southern Hemisphere small Odontoceti: a scoping review

open access: yesMammal Review, Volume 55, Issue 2, April 2025.
This review identifies key causes of morbidity and mortality in Southern Hemisphere small Odontoceti, highlighting significant anthropogenic threats and the enhanced need for conservation strategies. Key findings include high rates of entanglements and a diverse range of infectious pathogens. Abstract Marine mammals serve as sentinels for environmental

Establishment of an experimental system to analyse extracellular vesicles during apoplastic fungal pathogenesis

open access: yesJournal of Extracellular Biology, Volume 4, Issue 2, February 2025.
Abstract Phoma stem canker disease of oilseed rape (Brassica napus) is caused by the extracellular fungal pathogen Leptosphaeria maculans. Although this pathogen resides exclusively in apoplastic spaces surrounding plant cells, the significance of extracellular vesicles (EVs) has not been assessed.

Antimicrobial Peptides: A Promising Alternative to Conventional Antimicrobials for Combating Polymicrobial Biofilms

open access: yesAdvanced Science, Volume 12, Issue 1, January 9, 2025.
Antimicrobial peptides (AMPs) are promising alternatives to conventional treatments for polymicrobial biofilms, which increase pathogen resistance. AMPs disrupt biofilm extracellular matrices and microbial membranes, inhibiting biofilm formation and enhancing antibiotic efficacy. Current research addresses challenges like stability and production costs

Validation and clinical application of a nested PCR for paracoccidioidomycosis diagnosis in clinical samples from Colombian patients

open access: yesBrazilian Journal of Infectious Diseases, 2015
Paracoccidioidomycosis is a systemic and endemic mycosis, restricted to tropical and subtropical areas of Latin America. The infection is caused by the thermal dimorphic fungus Paracoccidioides brasiliensis and Paracoccidioides lutzii.
