Comparison of multi-locus genotypes detected in aspergillus fumigatus isolated ...
Morais, Susana; Toscano, Cristina; Simões, Helena; Carpinteiro, Dina; Viegas, Carla; Veríssimo, Cristina; Sabino, RaquelPublisher Copyright: © 2023 by the authors.; Background: Aspergillus fumigatus is a saprophytic fungus, ubiquitous in the environment and responsible for causing infections, some of them severe invasive infections. The high morbidity and mortality, together with the increasing burden of triazole-resistant isolates and the emergence of new risk groups, namely COVID-19 patients, have raised a crescent awareness o...
Culture media and sampling collection method for aspergillus spp. Assessment
Viegas, Carla; Dias, Marta; Carolino, Elisabete; Sabino, RaquelCulturing is still the most widely used method for determining fungal growth. Thus, is important to identify the most suitable culture media to assess Aspergillus spp. The aim of this study was to analyze data obtained from previous studies, aiming at identifying the most suitable culture media (malt extract agar (MEA) or dichloran-glycerol agar (DG18) to assess Aspergillus spp. isolation and growth. This study...
Azole-resistant aspergillus fumigatus harboring the TR34/L98H mutation
Gonçalves, Paulo; Melo, Aryse; Dias, Marta; Almeida, Beatriz; Caetano, Liliana Aranha; Veríssimo, Cristina; Viegas, Carla; Sabino, RaquelINTRODUCTION: The frequency in detection of azole-resistant Aspergillus fumigatus isolates has increased since 2010. In Portugal, the section Fumigati is one of the most frequent, and resistant strains to have been found in clinical and environmental contexts. Although several cryptic species within the Fumigati section show intrinsic resistance to azoles, one factor driving (acquired) resistance is selective p...
Trends on aspergillus epidemiology
Sabino, Raquel; Gonçalves, Paulo; Martins Melo, Aryse; Simões, Daniela; Oliveira, Mariana; Francisco, Mariana; Viegas, Carla; Carvalho, DinahIdentification of Aspergillus to species level is important since sibling species may display variable susceptibilities to multiple antifungal drugs and also because correct identification contributes to improve the knowledge of epidemiological studies. Two retrospective laboratory studies were conducted on Aspergillus surveillance at the Portuguese National Mycology Reference Laboratory. The first, covering th...

Fungal contaminants in drinking water regulation?
Babič, Monika Novak; Gunde-Cimerman, Nina; Vargha, Márta; Tischner, Zsófia; Magyar, Donát; Veríssimo, Cristina; Sabino, Raquel; Viegas, CarlaMicrobiological drinking water safety is traditionally monitored mainly by bacterial parameters that indicate faecal contamination. These parameters correlate with gastro-intestinal illness, despite the fact that viral agents, resulting from faecal contamination, are usually the cause. This leaves behind microbes that can cause illness other than gastro-intestinal and several emerging pathogens, disregarding no...
Occupational exposure to fungi and particles in animal feed industry
Viegas, Carla; Faria, Tiago; Carolino, Elisabete; Sabino, Raquel; Gomes, Anita Quintal; Viegas, SusanaBackground: Very few studies regarding fungal and particulate matter (PM) exposure in feed industry have been reported, although such contaminants are likely to be a significant contributing factor to several symptoms reported among workers. The purpose of this study has been to characterize fungal and dust exposure in one Portuguese feed industry. Material and Methods: Air and surface samples were collected an...
Analysis of surfaces for characterization of fungal burden
Viegas, Carla; Faria, Tiago; Meneses, Márcia; Carolino, Elisabete; Viegas, Susana; Gomes, Anita Quintal; Sabino, RaquelObjectives: Mycological contamination of occupational environments can be a result of fungal spores' dispersion in the air and on surfaces. Therefore, it is very important to assess it in both types of the samples. In the present study we assessed fungal contamination in the air and in the surface samples to show relevance of surfaces sampling in complementing the results obtained in the air samples. Material a...
Slaughterhouses fungal burden assessment
Viegas, Carla; Faria, Tiago; dos Santos, Mateus; Carolino, Elisabete; Sabino, Raquel; Gomes, Anita Quintal; Viegas, SusanaIn slaughterhouses, the biological risk is present not only from the direct or indirect contact with animal matter, but also from the exposure to bioaerosols. Fungal contamination was already reported from the floors and walls of slaughterhouses. This study intends to assess fungal contamination by cultural and molecular methods in poultry, swine/bovine and large animal slaughterhouses. Air samples were collect...
