Introduction: Fungal spores are numerous fragments dispersed through the air and, due to their tiny dimensions, are classied as bio aerosols, which consist of particles and derivatives of microorganisms such as bacteria, fungi, viruses, organic compounds, metabolites, toxins and other fragments. The stu Objectives: dy analyzed fungal contamination in air conditioning lters collected from 100 motor vehicles (light and heavy). Methods: Over a period of 8 months, 100 air conditioning lters from light vehicles (cars) and heavy vehicles (trucks) from the cities of Cuiabá and Várzea Grande, central region of Brazil, were collected and evaluated. The survey found 76 fungal genera in Results: all samples collected (100%), including toxigenic fungi such as Aspergillus, Penicillium, Cladosporium, Fusarium, Alternaria and Cryptococcus, indicating that indoor air quality can compromise the health of a portion of the population light vehicle user as well as professional truck drivers. The most prevalent aerial fungal spores recorded were of the genus Aspergillus (860; 37.79%) and Penicillium (240; 10.54%), followed by Cladosporium (119; 5.23%) and also Alternaria, Curvularia, Fusarium etc. and Candida yeasts (103;4.53%), Rhodotorula (66;2.90%) and Cryptococcus (44; 1.93%). Among the Aspergillus genus, the results showed the presence of the species A. avus, A. niger, A. fumigatus, A. ochraceus, A. terreus and A. clavatus, which cause severe allergic respiratory and pulmonary diseases. The maximum amount of spores was from species of the phylum Ascomycota (64; 84.21%), followed by Basidiomycota (6; 7.89%), Zygomicota and Mucoromycota (2; 2.63%) and nally Oomycota and Deuteromycota (1; 1.32%) respectively. The air in articially cooled enviro Conclusion: nments should provide comfort to its occupants, but it can pose a risk to human health if pathogenic and toxigenic fungi contaminate the air ltration systems in automobiles.
Resumo. O Brasil possui uma importância inquestionável no cenário da biodiversidade global o que o torna um dos países mais visados para este que é o terceiro maior comércio ilícito do mundo, o tráfico de animais silvestres. Mesmo com o reconhecimento da técnica molecular como importante ferramenta na identificação, ainda paira uma discussão sobre qual o melhor segmento de DNA a ser utilizado Cytb ou COI e se estes são efetivos para amostras degradadas, como é o caso das amostras forenses. Objetivo foi contribuir para dissolução dos questionamentos e depositar no banco de dados GenBank ® as sequências de DNA mitocondrial geradas. As
Water mites (Hydrachnidia) are common external parasites of the medically important mosquitoes (Culicidae). Between April 2014 and April 2015, 64 mites from three genus, Arrenurus 71.9%, Limnochares 3.1%, and Hydrachna 25.0%, were collected from female mosquitoes in two rural locations near Cuiabá, Mato Grosso, Brazil. Dipterous species parasitized by water mites belonging to seven species: Anopheles (Nys.) darling, An. evansae, Aedes (Och.) scapularis, Ae. serratus, Mansonia (Man.) wilsoni, Psorophora (Jan.) ferox, Ps. varipes. The most common specimens to accommodate the water mites were Anopheles (Nys.) darlingi and Psorophora (Jan.) varipes. The prevalence of parasitism of mosquitoes by water mites found in this study was less than 5. However, few studies have addressed the ecological role of mites and their biotopes, as well as host-parasite interactions in Brazil.
Background: COVID-19 is a rapidly transmissible pneumonia-like illness caused by SARS-CoV-2 that out broke in China in 2019 and is currently circulating worldwide. In the current context of the SARS-CoV-2 pandemic, complications are observed in clinical settings for the treatment of severe COVID-19 disease in nosocomial settings, due to cases of fungal co-infections. Objective: To carry out a review on fungal infections associated with respiratory infections caused by COVID-19 (Sars-Cov-2) and their aggravation. Methodology: The purpose of this study is to inform the reader about the characteristics of SARS-CoV-2 and the main fungal species that are affecting patients undergoing treatment for severe COVID-19, provoking discussion of the importance of the proposed topic, in relation to co-infections by different fungal microorganisms. Result: 80 scientific studies were selected, resulting from patients with COVID-19 and most commonly observed in patients with a history of comorbidities such as diabetes mellitus, hypertension, kidney disease, severe liver disease, oncological diseases, obesity and with severe COVID-19. These data do not represent the total number of records of the disease in the world, but cases reported by researchers in their series, showing the overlapping of fungal co-infection through the compromised immune status due to the use of therapeutic drugs, dysregulation of the microbiota, How to cite this paper: Mariscal, A.
