Pathogenic Rickettsia in ticks of spur-thighed tortoise (Testudo Graeca) sold i...
Barradas, P.F.; Mesquita, J.R.; Lima, C.; Cardoso, L.; Alho, A.M.; Ferreira, P.; Amorim, I.; De Sousa, R.; Gärtner, F.The dissemination of vector arthropods harbouring zoonotic pathogens through the uncontrolled transboundary trade of exotic and pet animals poses an important threat to Public Health. In the present report, we describe the introduction of pathogenic Rickettsia africae and R. aeschlimanni in ticks removed from imported tortoises in Qatar. A total of 21 ticks were collected from pet spur‐thighed tortoises (Testud...
Serological and molecular evidence of Bartonella henselae in cats from Luanda c...
Barradas, P.F.; De Sousa, R.; Vilhena, H.; Oliveira, A.C.; Luz, M.F.; Granada, S.; Cardoso, L.; Lopes, A.P.; Gonçalves, H.; Mesquita, J.R.; Ferreira, P.A total of 100 domestic cats from Luanda (Angola) were tested for the presence of antibodies against Bartonella henselae and spotted fever group of Rickettsia (SFGR) using indirect immunofluorescence assay (IFA). Molecular screening targeting the riboflavin synthase (ribC) gene for Bartonella and outer membrane protein B (ompB) gene for Rickettsia, using conventional PCR and sequencing was also performed in cat...
Detection of Anaplasma phagocytophilum, Candidatus Neoehrlichia sp., Coxiella b...
Santos, A.S.; de Bruin, A.; Veloso, A.R.; Marques, C.; Pereira da Fonseca, I.; De Sousa, R.; Sprong, H.; Santos-Silva, M.M.Tick-borne agents with medical relevance have been recorded in Portugal but little is known about their oc-currence in urban outdoor leisure areas. This study aimed to investigate ticks and tick-borne agents in threepublic parks of Lisbon’s metropolitan area. A total of 234 questing ticks belonging to eight species were found inParque Florestal de Monsanto (PFM). Ixodes ventalloi represented 40% of collections....
Neglected vector-borne zoonoses in Europe: Into the wild
Tomassone, L.; Berriatua, E; De Sousa, R.; Duscher, G.G.; Mihalca, A.D.; Silaghi, C.; Sprong, H.; Zintl, A.Wild vertebrates are involved in the transmission cycles of numerous pathogens. Additionally, they can affect the abundance of arthropod vectors. Urbanization, landscape and climate changes, and the adaptation of vectors and wildlife to human habitats represent complex and evolving scenarios, which affect the interface of vector, wildlife and human populations, frequently with a consequent increase in zoonotic ...
Primeiro caso de Tularémia de importação em Portugal
Nascimento, P.; Rico, M.T.; Roque, R.; De Sousa, R.; Núncio, M.S.; Lopes de Carvalho, I.A tularémia é uma zoonose causada pela bactéria Francisella tularensis, que se transmite ao homem por contacto directo com animais infectados, artrópodes, ar, água ou alimentos contaminados. Apesar de ser pouco frequente na Europa, têm sido notificados surtos recentes (Espanha,França,Escandinávia,Balcãs e Hungria) e casos esporádicos (Áustria,Itália e Reino Unido). Em Portugal, F. tularensis subsp. holarctica f...
Hepatitis A outbreak disproportionately affecting men who have sex with men (MS...
Ndumbi, P.; Freidl, G.S.; Williams, C.J.; Mårdh, O.; Varela, C.; Avellón, A.; Friesema, I.; Vennema, H.; Beebeejaun, K.; Ngui, S.L.; Edelstein, M.Between 1 June 2016 and 31 May 2017, 17 European Union (EU) and European Economic Area countries reported 4,096 cases associated with a multi-country hepatitis A (HA) outbreak. Molecular analysis identified three co-circulating hepatitis A virus (HAV) strains of genotype IA: VRD_521_2016, V16-25801 and RIVM-HAV16-090. We categorised cases as confirmed, probable or possible, according to the EU outbreak case def...
REVIVE, a surveillance program on vectors and vector-borne pathogens in Portuga...
Santos, A.S.; Santos Silva, M.; Lopes de Carvalho, I.; Milhano, N.; Chaínho, L.; Luz, T.; Parreira, P.; Gomes, S.; De Sousa, R.; Núncio, M.S.REVIVE is a national wide surveillance program on vector and vector-borne agents implement and coordinate by the National Institute of Health (CEVDI/INSA) in collaboration with other institutions of the Health Ministry. The programme started in 2008 with the surveillance of mosquitoes and later in 2011 was extended to ticks. The main goals of this project are to collect and identify vectors, updating our knowle...

The hard-tick fauna of mainland Portugal (Acari: Ixodidae): an update on geogra...
Santos-Silva, M. M.; Beati, L.; Santos, A. S.; De Sousa, R.; Núncio, M. S.; Melo, P.; Santos-Reis, M.; Fonseca, C.; Formosinho, P.; Vilela, C.This work is an updated revision of the available information on Portuguese ixodid tick species. It includes data on tick biology, ecology, taxonomy and host/pathogen-associations. The current list of Portuguese ixodid ticks comprises twenty species: Dermacentor marginatus (Sulzer, 1776), Dermacentor reticulatus (Fabricius, 1794), Haemaphysalis hispanica Gil Collado, 1938, Haemaphysalis inermis Birula, 1895, Ha...
Molecular characterization of a new isolate of Borrelia lusitaniae derived from...
de Carvalho, Isabel Lopes; Zeidner, N.; Ullmann, A.; Hojgaard, A.; Amaro, F.; Zé-Zé, Líbia; Alves, M.J.; De Sousa, R.; Piesman, J.; Núncio, M.S.A total of 196 small mammals were collected in Portugal and tested for Borrelia burgdorferi sensu lato. Tissue samples were taken from each animal and cultured in Barbour-Stoenner-Kelly (BSK)-II medium. The single strain of spirochete isolated was confirmed as Borrelia lusitaniae by genetic analyses. This is the first report of B. lusitaniae isolated from Apodemus sylvaticus.
