Published: May 2021

Objectives: The main aim of this work was to compare the methods of DNA isolation in the moulds of genus with special regard to the amount and purity of the DNA acquired. The acquired DNA was then amplified by specific real-time PCR.

Design: Five DNA extraction procedures were carried out in a Class 2 Biosafety cabinet in a dedicated room with suitable biosafety precautions and appropriate biowaste disposal methods. A total of 6 clinical strains were used.

Results: From the viewpoint of concentration and purity, methods A shown abundant amount of fungal DNA whereas methods E report a pure fungal DNA with R260/280 of 1.7 near the optimal 1.8. The DNA quantity reach statistically difference at ANOVA test with p value 0.0005.

Conclusion: Overall, the E method was the most efficient method in the extraction of DNA from fungal cultures compared to the other methods considering time, cost, technical expertise, and instrumentation. Use of this assay will allow researchers to obtain DNA from fungi quickly for use in molecular assays.

Phototoxic reaction to oral terbinafine due to Tinea capitis in a child.

We report the case of an 18-month-old boy who developed a phototoxic skin reaction to terbinafine on his scalp, ears, and face in the form of disseminated erythematous plaques, which resembled subacute lupus erythematosus (SCLE) in their clinical presentation. Skin changes appeared a short time after the boy was exposed to sunlight during the period of time when he was treated with oral terbinafine due to Microsporum canis fungal scalp infection. Tinea capitis is a common dermatophyte infection primarily affecting prepubertal children (1).

Microbial pathogens generate extracellular vesicles (EVs) for intercellular communication and quorum sensing. Microbial EVs also induce inflammatory pathways within host innate immune cells. We previously demonstrated that EVs secreted by trigger type I interferon signaling in host cells specifically via the cGAS-STING innate immune signaling pathway.

Molecular Identification and Antifungal Susceptibility of Fusarium spp. Clinical Isolates.

Mycoses

January 2025

Clinical Microbiology Laboratory, Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán, Mexico City, Mexico.

Background: Accurate identification of Fusarium species requires molecular identification. Treating fusariosis is challenging due to widespread antifungal resistance, high rates of treatment failure, and insufficient information relating antifungal susceptibility to the clinical outcome. Despite recent outbreaks in Mexico, there is limited information on epidemiology and antifungal susceptibility testing (AST).

Background: Biological control methods involving entomopathogenic fungi like Beauveria bassiana have been shown to be a valuable approach in integrated pest management as an environmentally friendly alternative to control pests and pathogens. Identifying genetic determinants of pathogenicity in B. bassiana is instrumental for enhancing its virulence against insects like the resistant soybean pest Piezodorus guildinii.

Ochratoxin A (OTA) is a mycotoxin, a common contaminant of grapes and their derivatives, such as wine, and classified as possible human carcinogen (group 2B) by the International Agency for Research on Cancer (IARC). is the main producer of OTA in grapes. The stability of the molecule and the poor availability of detoxification systems makes the control of in vineyards the main strategy used to reduce OTA contamination risk.
