Screening wild birds for tick-borne zoonotic pathogens in Portugal
Loureiro, Filipa; Mesquita, João R.; Cardoso, Luis; Santos-Silva, S.; Moreira, G.; Bento, J. T.; Silva, F.; Barradas, P. F.; Matos, M.Wild birds may be involved in the transmission of agents of infectious diseases, including zoonoses, a circumstance which raises a number of public and animal health issues. Migratory bird species play a significant role in the introduction of tick-borne pathogens to new geographic areas, contributing to the dissemination of various etiological agents. This preliminary study aimed to assess the occurrence of fo...
Molecular detection of Rickettsia spp. in ticks and feas collected from rescued...
Barradas, P. F.; Mesquita, J. R.; Mateus, T. L.; Ferreira, P.; Amorim, I.; Gartner, F.; Sousa, R.Hedgehogs (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...
Crenosoma striatum in lungs of European hedgehogs (Erinaceus europeus) from Por...
Barradas, P. F.; Flores, A. R.; Mateus, T. L.; Carvalho, F.; Gärtner, F.; Amorim, I.; Mesquita, J. R.Crenosoma striatum is a host-specifi c metastrongiloid nematode causing respiratory tract disease in hedgehogs (Erinaceus europaeus). Since few studies have reported C. striatum in hedgehogs and little genetic data is available concerning this lungworm, this study aimed to determine the occurrence of C. striatum in a population sample of hedgehogs from Portugal, additionally providing morphological, histologica...
Serological evidence of Rickettsia exposure among patients with unknown fever o...
Barradas, P. F.; Neto, Z.; Mateus, T. L.; Teodoro, A. C.; Duarte, L.; Gonçalves, H.; Ferreira, P.; Gärtner, F.; Sousa, R.; Amorim, I.Spotted fever group Rickettsia (SFGR) is one among the aetiologies that cause fever of unknown origin in Angola. Despite their occurrence, there is little information about its magnitude in this country either because it is misdiagnosed or due to the lack of diagnostic resources. For this purpose, eighty-seven selected malaria- and yellow fever-negative serum specimens collected between February 2016 and March ...
