Molecular evidence of sporadic Coxiella burnetii excretion in sheep milk, centr...
Pires, Humberto; Santos-Silva, Sérgio; Cruz, Andreia V.S.; Cardoso, Luís; Lopes, Ana Patrícia; Pereira, Maria; Nóbrega, Carmen; Mega, CristinaCoxiella burnetii is the etiologic agent of Q fever, a worldwide zoonosis. Cattle, sheep and goats are considered the main reservoirs of the disease. Transmission to humans occurs mainly through the inhalation of infectious aerosols from milk, faeces, urine, and birth products from infected ruminants. In this study, a 2-year longitudinal approach was performed to ascertain the excretion of C. burnetii in bulk t...

Rickettsia massiliae circulation in sheep and attached Rhipicephalus sanguineus...
Mesquita, João R.; Santos-Silva, Sérgio; de Sousa Moreira, Alícia; Baptista, Maria Beatriz; Cruz, Rita; Esteves, Fernando; Vala, HelenaRickettsiosis is considered an emerging/re-emerging vector-borne disease that causes signifcant public health threats. Ticks are reservoirs and vectors of Rickettsia having a signifcant role in the transmission of rickettsiae. In Portugal, little is known about tick-borne Rickettsia species in sheep. Therefore, this study aimed to investigate rickettsiae infection in ticks and their sheep host from 27 farms in ...
Molecular detection of human pathogenic gastric helicobacter species in wild ra...
Nunes, Francisco Cortez; Mateus, Teresa Letra; Teixeira, Sílvia; Barradas, Patrícia F.; Gärtner, Fátima; Haesebrouck, Freddy; Amorim, IrinaWildlife plays a major role in the maintenance and transmission of multihost pathogens. Several Helicobacter spp. have been described to have zoonotic potential; thus, human, domestic and wild animal interactions deserve more attention. In this study, the presence of the DNA of human pathogenic gastric Helicobacter species was determined in gastric samples collected from wild rabbits and wild quails during the ...
Molecular detection of Rickettsia spp. in ticks and fleas collected from rescue...
Barradas, Patrícia F.; Mesquita, João R.; Mateus, Teresa L.; Ferreira, Paula; Amorim, Irina; Gärtner, FátimaHedgehogs (e.g., Erinaceus europaeus, E. roumanicus) are wild mammals that frequently are observed near residential areas. The aim of this study was to investigate ticks and feas collected from European hedgehogs in Portugal and to evaluate the prevalence of Rickettsia in those ectoparasites. Ticks and feas were identifed by morphological and molecular methods, and molecular detection by PCR and genotypic chara...
