Multiple Phlebovirus (Bunyaviridae) genetic groups detected in Rhipicephalus, Hyalomma and Dermacentor ticks from southern Portugal

In the last decade, various research groups have reported a large diversity of new tick-borne phleboviruses, mostly prompted by the discovery of important human pathogens such as the Heartland and severe fever with thrombocytopenia syndrome viruses. Since these analyses have rarely been conducted using ticks collected from Southern Europe, this study was carried out so […]

First molecular detection of Leishmania tarentolae-like DNA in Sergentomyia minuta in Spain

Phlebotomine sand flies (Diptera, Psychodidae) are vectors of multiple Leishmania species, among which Leishmania infantum stands out as a being frequently pathogenic to humans and dogs in Mediterranean countries. In this study, Sergentomyia minuta sand flies were collected using CDC miniature light traps in different 431 biotopes from Southwest Spain. A total of 114 females were tested for the presence of Leishmania DNA […]

Molecular detection of tick-borne bacteria and protozoa in cervids and wild boars from Portugal

Tick-borne bacteria and protozoa by molecular sequencing The authors assess the presence of tick-borne bacteria and protozoa by molecular sequencing. Cervids and wild boars can can act as reservoir of different tick-borne pathogens, such as bacteria, parasites and viruses. The researchers collected 141 blood samples from free-ranging ungulates including 73 red deer, 65 wild boars and three fallow deer. Moreover, […]

Molecular identification of Borrelia genus in questing hard ticks from Portugal: Phylogenetic characterization of two novel Relapsing Fever-like Borrelia sp.

Molecular identification of Borrelia genus Several studies reported pathogenic species of Borrelia related to those that cause Tick-borne Relapsing Fever (RF). However, this studies unexpectedly suggested their transmission by hard ticks rather than by soft ticks. This study aimed to update the presence of B. burgdorferi s.l. species in ticks from several districts of Portugal, […]

Clinical and laboratory profile of Zika virus infection in dengue suspected patients: A case series

BACKGROUND: The Zika virus (ZIKV) is an emerging arthropod-borne virus related to the dengue virus (DENV), and shows a similar clinical profile as other arboviral diseases, such as dengue and chikungunya virus (CHIKV). Historically, ZIKV has been associated with sporadic cases of human infection, but is now responsible for outbreaks worldwide. In Brazil, cases have […]
