Presence of Alphacoronavirus in Tree- and Crevice-Dwelling Bats from Portugal
Hemnani, M; da Silva, PG; Thompson, G; Poeta, P; Rebelo, H; Mesquita, JRCoronaviruses (CoVs) are RNA viruses capable of infecting a wide range of hosts, including mammals and birds, and have caused significant epidemics such as the ongoing COVID-19 pandemic. Bats, the second most diverse mammalian order, are hosts for various CoVs due to their unique immune responses and ecological traits. This study investigates CoV prevalence in crevice- and tree-dwelling bats in Portugal, a coun...
Detection and Prevalence of Coronaviruses in European Bats: A Systematic Review
Hemnani, M; da Silva, PG; Thompson, G; Poeta, P; Rebelo, H; Mesquita, JRBats are known hosts for a wide range of coronaviruses (CoVs), including those that cause severe acute respiratory syndrome (SARS-CoV-1) and Middle East respiratory syndrome (MERS-CoV). With the emergence of the COVID-19 pandemic caused by the SARS-CoV-2 virus, it has become increasingly important to understand the diversity and prevalence of CoVs in bat populations. This systematic review aimed to compile stud...
First Report of Alphacoronavirus Circulating in Cavernicolous Bats from Portugal
Hemnani, M; da Silva, PG; Thompson, G; Poeta, P; Rebelo, H; Mesquita, JRThe emergence of novel coronaviruses (CoVs) has emphasized the need to understand their diversity and distribution in animal populations. Bats have been identified as crucial reservoirs for CoVs, and they are found in various bat species worldwide. In this study, we investigated the presence of CoVs of four cavernicolous bats in six locations in the centre and south of Portugal. We collected faeces, anal, and b...
Molecular Detection and Characterization of Coronaviruses in Migratory Ducks fr...
Hemnani, M; Rodrigues, D; Santos, N; Santos-Silva, S; Figueiredo, ME; Henriques, P; Ferreira-e-Silva, J; Rebelo, H; Poeta, P; Thompson, G; Mesquita, JRCoronaviruses (CoVs) are part of the Coronaviridae family, and the genera Gamma (γ) and Delta (δ) are found mostly in birds. Migratory birds have an enormous potential for dispersing pathogenic microorganisms. Ducks (order Anseriformes) can host CoVs from birds, with pathogenic expression and high economic impact. This study aimed to identify and characterize the diversity of CoVs in migratory ducks from Portug...
A large outbreak of Legionnaires’ Disease in an industrial town in Portugal
George, F; Shivaji, T; Pinto, CS; Serra, LA; Valente, J; Albuquerque, MJ; Vicêncio, PC; San-Bento, A; Diegues, P; Nogueira, PJ; Marques, T; Rebelo, HBackground We describe the investigation and control of an outbreak of Legionnaires’ disease in Portugal in October, November and December 2014. Methods Confirmed cases were individuals with pneumonia, laboratory evidence of Legionella pneumophila serogroup 1 and exposure, by residence, occupational or leisure to the affected municipalities. 49 possible sources were reduced to four potential sources, all indust...
