Etiology, Treatment and Prognosis of Acute Pericarditis
Fernandes Serodio, João; Trindade, Miguel; Achega, Miguel; Faria, Daniel; Maurício, Joana; Batista, Frederico; Favas, Catarina; Delgado Alves, JoséIntroduction: Acute pericarditis is a common inflammatory condition of the pericardium usually assumed to be viral or idiopathic. Despite recent treatment improvements, information is scarce regarding etiology and prognosis. Our aim was to determine the incidence of pericarditis with a known etiology and assess clinical prognostic predictors. Material and Methods: A clinical retrospective analysis of hospitaliz...
Evolution and diversity of alpha-carbonic anhydrases in the mantle of the Medit...
Cardoso, João CR; Ferreira, Vinicius; Zhang, Xushuai; Anjos, Liliana; Félix, Rute; Batista, Frederico; Power, DeborahThe α-carbonic anhydrases (α-CAs) are a large and ancient group of metazoan-specific enzymes. They generate bicarbonate from metabolic carbon dioxide and through calcium carbonate crystal formation play a key role in the regulation of mineralized structures. To better understand how α-CAs contribute to shell mineralization in the marine Mediterranean mussel (Mytilus galloprovincialis) we characterized them in t...
Complete genome of a marine bacterium Vibrio chagasii ECSMB14107 with the abili...
Liang, Xiao; Wang, Jin-Song; Liu, Yu-Zhu; Peng, Li-Hua; Li, Yi-Feng; Batista, Frederico; Power, Deborah; Gui, Lang; Yang, Jin-LongVibrio strains are pervasive in the aquatic environment and may form pathogenic and symbiotic relationships with the host. Vibrio chagasii ECSMB14107 was isolated from natural biofilms and is used as a model to elucidate the role of Vibrio in hard-shelled mussel (Mytilus coruscus) settlement, health and disease. The genome of the Vibrio strain ECSMB14107, comprised of two circular chromosomes that together enco...
Two toll-like receptors identified in the mantle of Mytilus coruscus are abunda...
Li, Yi-Feng; Liu, Yu-Zhu; Chen, Yan-Wen; Chen, Ke; Batista, Frederico; Cardoso, João CR; Chen, Yu-Ru; Peng, Li-Hua; Zhang, Ya; Zhu, You-TingToll-like receptors (TLRs) are a large family of pattern recognition receptors (PREs) that play a critical role in innate immunity. TLRs are activated when they recognize microbial associated molecular patterns (MAMPs) of bacteria, viruses, or fungus. In the present study, two TLRs were isolated from the mantle of the hard-shelled mussel (Mytilus coruscus) and designated McTLR2 and McTLR3 based on their sequenc...
Uncovering the immunological repertoire of the carpet shell clam Ruditapes decu...
Batista, Frederico; Churcher, Allison; Manchado, Manuel; Leitão, Alexandra; Power, DeborahThe grooved carpet-shell clam Ruditapes decussatus is native to the Northern Atlantic and Mediterranean Sea and has a high commercial value. It is one of the main native bivalve species cultured in Europe. The main objective of the present study was to gain further insights into the immunological repertoire of R. decussatus through a transcriptomic approach. Pooled mantle samples of eight R. decussatus individu...
Elevated seawater temperatures decrease microbial diversity in the gut of mytil...
Li, Yi-Feng; Yang, Na; Liang, Xiao; Yoshida, Asami; Osatomi, Kiyoshi; Power, Deborah; Batista, Frederico; Yang, Jin-LongThe gut microbial community is critical for the host immune system, and in recent years, it has been extensively studied in vertebrates using 'omic' technologies. In contrast, knowledge about how the interactions between water temperature and diet affect the gut microbiota of marine invertebrates that do not thermoregulate is much less studied. In the present study, the effect of elevated seawater temperature a...
Occurrence and characterization of pearls from oysters of the genus Crassostrea
Batista, Frederico; Grade, Ana; Power, Deborah; Ruano, Francisco; Harper, Elizabeth M.The occurrence of pearls in the true' oysters, the Ostreioidea, is poorly documented despite being the most produced mollusc species in the world. Oysters of the Crassostrea genus were collected in two different sites in southern Portugal where both Crassostrea angulata and C. gigas are present, namely in: (1) the Ria Formosa lagoon where pearls were not observed (N = 446); and (2) the Guadiana estuary where pe...
Asynchrony in settlement time between the closely related oysters Crassostrea a...
Batista, Frederico; G Fonseca, Vera; Ruano, Francisco; Boudry, PierreThe Portuguese oyster Crassostrea angulata and the Pacific oyster Crassostrea gigas are very closely related species originating from Asia that were introduced in Europe. The objectives of the present study were to determine if there is asynchrony in settlement time of C. angulata and C. gigas larvae in an area where both taxa coexist and if hybridization between the two species occurs throughout the breeding s...
Experimental infection of European flat oyster Ostrea edulis with ostreid herpe...
Sanmartin, Monserrat Lopez; Power, Deborah; de la Herran, Roberto; Navas, Jose I.; Batista, FredericoOstreid herpesvirus 1 (OsHV-1) infections have been reported in several bivalve species. Mortality of Pacific oyster Crassostrea gigas spat has increased considerably in Europe since 2008 linked to the spread of a variant of OsHV-1 called var. In the present study we demonstrated that O. edulis juveniles can be infected by OsHV-1 mu var when administered as an intramuscular injection. Mortality in the oysters i...
New insights about the introduction of the Portuguese oyster, Crassostrea angul...
Lallias, Delphine; Power, Deborah; Ruano, Francisco; Leitão, Alexandra; Drago, Teresa; King, Jonathan W.; Boudry, Pierre; Batista, FredericoIt is commonly presumed that the Portuguese oyster Crassostrea angulata was introduced into the North East (NE) Atlantic from Asia. The analysis of the nucleotide sequence of a highly polymorphic non-coding mitochondrial region (major noncoding region - MNR) of C. angulata samples collected in Europe (Portugal), Africa (Morocco) and Asia (Shantou and Taiwan) provided new insight into the introduction of this sp...
