Evidence for sporadic Coxiella burnetii excretion in sheep milk, central Portugal
Pires, Humberto; Silva, S. Santos; Cruz, A.; Cardoso, Luís; Lopes, A.P.; Pereira, M.A.; Nóbrega, C.; Mega, A.C.; Santos, C.; Cruz, R.; Esteves, F.Coxiella burnetii, the causative agent of Q fever, is a globally distributed zoonosis, with cattle, sheep, and goats considered the main reservoirs of the disease (Agger et al,., 2013; Bento et al., 2023). Human transmission primarily occurs through inhaling infections aerosols from milk, faeces, urina, and birth products from infected ruminants. This study used a 2-year longitudinal approach to investigate C. ...
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...
Portuguese consensus document for the management of alpha-1-antitrypsin deficiency
Lopes, A.P.; Mineiro, M.A.; Costa, F.; Gomes, J.; Santos, C.; Antunes, C.; Maia, D.; Melo, R.; Canotilho, M.; Magalhães, E.; Vicente, I.; Valente, C.Alpha-1-antitrypsin deficiency (AATD) is a genetic autosomal codominant disorder caused by mutations in SERPINA1 gene. It is one of the most prevalent genetic disorders, although it remains underdiagnosed. Whereas at international level there are several areas of consensus on this disorder, in Portugal, inter-hospital heterogeneity in clinical practice and resources available have been adding difficulties in re...
Prevalence of Babesia microti-like infection in red foxes (Vulpes vulpes) from ...
Cardoso, L.; Cortes, H.C.E.; Reis, A.; Rodrigues, P.; Simões, M.; Lopes, A.P.; Vila-Viçosa, M.J.; Talmi-Frank, D.; Eyal, O.; Solano-Gallego, L.Prevalence of Babesia microti-like infection in red foxes (Vulpes vulpes) from Portugal Abstract The prevalence of piroplasm (order Piroplasmida) infection was assessed in blood and bone marrow samples from 91 red foxes (Vulpes vulpes) from northern, central and southern Portugal by means of molecular methods. PCR for the 18S rRNA gene of Babesia spp. followed by sequencing revealed 63 foxes positive for the Ba...
Seroepidemiology of Toxoplasma gondii infection in women from the North of Port...
Lopes, A.P.; Dubey, J.P.; Moutinho, O.; Gargate, M.J.; Vilares, A.; Rodrigues, M.; Cardoso, L.Seroprevalence of Toxoplasma gondii infection and associated risk factors were investigated in 401 women of childbearing age from the North of Portugal. Of the 98 (24·4%) seropositive women, 92 (93·9%) only had immunoglobulin (Ig)G, two (2·0%) only had IgM, and four (4·1%) others had both IgG and IgM. Risk factors for T. gondii infection in women were: engaging in soil-related activities without gloves [odds ra...
