Claudin and Rab proteins are key molecular components involved in coccidiosis r...
Varela-Martínez, Endika; Afonso, Ana; Mainou, Dimitra; Teixeira, Fábio; Nunes, Telmo; Vieira, Pedro; Sarraguça, Inês; Martins, CristinaBackground Although coccidial infection is often asymptomatic in sheep, both clinical and subclinical forms of the disease are linked to considerable production losses, mainly in young lambs. Studies aiming to identify genetic markers for use in selection programs towards increasing genetic resistance to coccidiosis are lacking and have yet to be performed in Portuguese Merino sheep. The purpose of this study w...
Occurrence and risk factors of equine piroplasmosis in Portugal: A five-year re...
Cabete, Ana; Xufre, Ângela; Padre, Ludovina; Bettencourt, Elisa; Nunes, Telmo; Gomes, JacintoEquine piroplasmosis (EP) is a tick-borne disease of equids caused by Theileria equi, Theileria haneyi, and Babesia caballi. EP is endemic in most tropical and subtropical regions worldwide, and there is a likelihood that it is also endemic in Portugal. This retrospective study aimed to determine the seroprevalence, prevalence, and potential risk factors of EP in our country over the past five years. A total of...

Tuberculose Bovina no Alentejo Estudo Epidemiológico de uma Zoonose Emergente
Ferreira, Amália; Mariano, Isabel; Amorim, António; Serralha, Alda; Carrilho, Emília; Caetano, Maria do Carmo; Fonseca, Maria Isabel; Melo, MárioA erradicação da tuberculose humana é uma prioridade das autoridades sanitárias a nível mundial, não só pelo aumento do número de casos, agravados por situações de imunossupressão, como pelo aparecimento de estirpes resistentes aos antibióticos, que tornam o quadro bem mais dramático. Nos animais, a evolução arrastada, com sintomatologia pouco expressiva e a enorme capacidade de sobrevivência da bactéria (devid...
Pollen morphology of the endemic genera of the Madeira archipelago, Portugal
Esposito, Fabiana; Morgado, L.N.; Nunes, Telmo; Rego, Carla José Azevedo; Fernandes, Francisco; Boieiro, MárioABSTRACT: This study presents the first palynological characterisation of the five endemic plant genera of the Madeira archipelago: Chamaemeles Lindl, Melanoselinum Hoffm., Monizia Lowe, Musschia Dumort and Sinapidendron Lowe. Pollen grain morphology of ten endemic species was studied using light and scanning electron microscopy techniques. The size and shape of pollen grains, the polar axis, the equatorial dia...

Burden of disease estimation based on Escherichia coli quantification in ready-...
Antunes, Leonor; João, António Lopes; Nunes, Telmo; Henriques, Ana RitaShiga toxin-producing E. coli (STEC), enterotoxigenic E. coli (ETEC) and enteropathogenic E. coli (EPEC) are associated with the onset of gastroenteritis with different severities, and STEC has been associated with other sequelae, such as hemolytic uremic syndrome and end stage renal disease. The main goal of this study was to estimate the annual foodborne burden of disease associated with STEC, ETEC and EPEC i...
Impact of endemic Besnoitiosis on the performance of a dairy cattle herd
Anastácio, Catarina; Bexiga, Ricardo; Nolasco, Sofia; Zúquete, Sara; Delgado, Inês L. S.; Nunes, Telmo; Leitão, AlexandreThis study aimed to assess the effect of Besnoitia besnoiti infection on the reproductive and productive performance of a dairy cattle herd. A serological screening was performed by indirect fluorescent antibody test (IFAT) on every animal aged over one year (n = 262). Subsequently, 211 animals were clinically examined, with 96 of those being screened for detection of sclerocysts. The overall seroprevalence was...
Veterinary syndromic surveillance using swine production data for farm health m...
Merca, Carolina; Lindell, Clemensson; Ernholm, L.; Selling, Eliasson; Nunes, Telmo; Sjolund, M.; Dorea, F. C.The use of syndromic surveillance (SyS) has grown in animal health since the 2010s, but the use of production data has been underexplored due to methodological and practical challenges. This paper aimed to tackle some of those challenges by developing a SyS system using production data routinely collected in pig breeding farms. Health-related indicators were created from the recorded data, and two different tim...
Zoonotic visceral leishmaniasis : new insights on innate immune response by blo...
Rodrigues, Armanda Viana; Valerio-Bolas, Ana; Alexandre-Pires, Graça; Aires Pereira, Maria; Nunes, Telmo; Ligeiro, Dario; Pereira da Fonseca, IsabelL. infantum is the aetiological agent of zoonotic visceral leishmaniasis (ZVL), a disease that affects humans and dogs. Leishmania parasites are well adapted to aggressive conditions inside the phagolysosome and can control the immune activation of macrophages (MØs). Although MØs are highly active phagocytic cells with the capacity to destroy pathogens, they additionally comprise the host cells for Leishmania i...
