Burkholderia pseudomallei is a Gram-negative bacillus and the causative agent of melioidosis, a serious infection associated with high mortality rate in humans. It can be naturally found as an environmental saprophyte in soil or stagnant water, and rice paddies that predominate in regions of endemicity such as Northeast Thailand. B. pseudomallei is a Biosafety Level 3 organism due to risks of aerosolization and...
Wild birds may act as reservoirs for zoonotic pathogens and may be mechanical carriers of pathogen infected vector ticks through long distances during migration. The aim of this study was to assess tick infestation patterns in birds in Portugal and the prevalence of tick infection by Borrelia burgdorferi s.l. using PCR techniques. Seven tick species were collected from birds including Haemaphysalis punctata, Hy...
In this work, a historical and epidemiological review of relapsing fever in mainland Portugal is made, analysing the most important aspects concerning the aetiological agent (Borrelia hispanica), vector, reservoir, clinical casuistic and treatment. In view of the recent isolation in some countries of relapsing fever Borrelia complex in hard ticks (Ixodidae), when the usual vectors are soft ticks (Argasidae), th...
