Correia, Gil; Rodrigues, Luís; Afonso, Mariana; Mota, Marta; Oliveira, Joana; Soares, Rui; Tomás, Ana Luísa; Reichel, Anna; Silva, Patrícia M.SARS-CoV-2 transmission occurs mainly indoors, through virus-laden airborne particles. Although the presence and infectivity of SARS-CoV-2 in aerosol are now acknowledged, the underlying circumstances for its occurrence are still under investigation. The contamination of domiciliary environments during the isolation of SARS-CoV-2-infected patients in their respective rooms in individual houses and in a nursing ...
Pyomelanin synthesis in alternaria alternata inhibits DHN-Melanin synthesis and...
Fernandes, Chantal; Mota, Marta; Barros, Lillian; Dias, Maria Inês; Ferreira, Isabel C.F.R.; Piedade, Ana P.; Casadevall, Arturo; Gonçalves, TeresaThe genus Alternaria includes several of fungi that are darkly pigmented by DHNmelanin. These are pathogenic to plants but are also associated with human respiratory allergic diseases and with serious infections in immunocompromised individuals. The present work focuses on the alterations of the composition and structure of the hyphal cell wall of Alternaria alternata occuring under the catabolism of L-tyrosine...

Identification of Fungi Involved in Onychomycosis in Patients of a Spanish Rura...
Marcos-Tejedor, Felix; Mota, Marta; Iglesias-Sánchez, María José; Mayordomo, Raquel; Gonçalves, TeresaOnychomycosis is one of the most frequent reasons for visiting podiatrist clinics. Complementary tests and the accurate identification of the infectious agents are key issues for a successful treatment of onychomycosis. This is particularly important when lifestyle, age and immunodepressed patients increase the prevalence of non-dermatophyte fungal infection. In this paper, we describe issues related to onychom...
Dental caries and bacterial load in saliva and dental biofilm of type 1 diabeti...
Coelho, Ana; Paula, Anabela; Mota, Marta; Laranjo, Mafalda; Abrantes, Margarida; Carrilho, Francisco; Ferreira, Manuel; Silva, Mário; Botelho, FilomenaObjectives: Since most of the studies evaluates diabetics on multiple daily injections therapy and continuous subcutaneous insulin infusion may help gain better metabolic control and prevent complications, the objective of this study was to evaluate the prevalence of dental caries, the unstimulated salivary flow rate and the total bacteria load, Streptococcus spp. levels and Lactobacillus spp. levels in saliva ...
Is the chlorophyll derivative Zn(II)e6Me a good photosensitizer to be used in r...
Diogo, Patrícia; Mota, Marta; Fernandes, Chantal; Sequeira, Diana; Palma, Paulo; Caramelo, Francisco; Neves, M. Graça P. M. S.; Faustino, M Amparo F.The aim of this study was to assess antimicrobial efficacy and cytotoxic outcomes of a chlorophyll based photosensitizer (PS) Zn(II)chlorin e6 methyl ester (Zn(II)e6Me), when applied to human dentin discs and root blocks infected with 48 h biofilms. The results were compared with the ones obtained with FotoSan® (commercial Toluidine Blue O formulation) and 3% sodium hypochlorite (NaOCl).
Antimicrobial Photodynamic Therapy against Endodontic Enterococcus faecalis and...
Diogo, Patrícia; Fernandes, Chantal; Caramelo, Francisco; Mota, Marta; Miranda, Isabel M.; Faustino, M. A. F.; Neves, M. G. P. M. S.Endodontic biofilms eradication from the infected root canal system remains as the primary focus in endodontic field. In this study, it was assessed the efficacy of antimicrobial Photodynamic Therapy (aPDT) with the Zn(II)chlorin e6 methyl ester (Zn(II)e6Me) activated by red light against monospecies and mixed biofilms of Enterococcus faecalis and Candida albicans. The results were compared with the ones obtain...

Rodrigues, Lisa; Miranda, Isabel M.; Andrade, Geanne M.; Mota, Marta; Cortes, Luísa; Rodrigues, Acácio G.; Cunha, Rodrigo A.; Gonçalves, TeresaOpportunistic gut infections and chronic inflammation, in particular due to overgrowth of Candida albicans present in the gut microbiota, are increasingly reported in the elder population. In aged, adult and young mice, we now compared the relative intestinal over-colonization by ingested C. albicans and their translocation to other organs, focusing on the role of adenosine A2A receptors that are a main stop si...
