Detection and Characterization of Visceral Anisakid Nematodes in Blue Whiting f...
Rigkou, A; Hemnani, M; Martins, AL; Mesquita, JRThis study employs molecular detection techniques, including conventional PCR and Sanger sequencing, to investigate the prevalence, species composition and public health implications of Anisakid nematodes in blue whiting (Micromesistius poutassou) caught off the Portuguese coast. With Portugal’s high fish consumption rates and increasing preference for raw or undercooked seafood, the risk of parasitic infection...
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...
Airborne SARS-CoV-2 is more frequently detected in environments related to chil...
da Silva, PG; Hemnani, M; Gonçalves, J; Rodriguéz, E; García-Encina, PA; Nascimento, MSJ; Sousa, SIV; Myrmel, M; Mesquita, JRThis study investigates the presence of SARS-CoV-2 in indoor and outdoor environments in two cities in Norway between April and May 2022. With the lifting of COVID-19 restrictions in the country and a focus on vaccination, this research aims to shed light on the potential for virus transmission in various settings. Air sampling was conducted in healthcare and non-healthcare facilities, covering locations freque...
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...
A Systematic Review of Hepatitis E Virus Detection in Camels
Santos-Silva, S; Hemnani, M; Lopez-Lopez, P; Gonçalves, HMR; Rivero-Juarez, A; van der Poel, WHM; Nascimento, MSJ; Mesquita, JRSimple Summary: Acute hepatitis, which is a rising public health issue globally, is mostly caused by the hepatitis E virus (HEV). There is a potential risk of camel-borne zoonotic HEV infection in the desert regions of the Middle East and Africa, where camels frequently interact with human populations and camel-derived food products constitute a component of the food chain. To better understand the current stat...
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...
