Are eddies nature's trigger to enhance biological productivity in the Bay of Bengal?
[1] The Bay of Bengal is traditionally considered to be a less productive basin compared to the Arabian Sea. Despite the contrasting chlorophyll and primary productivity pattern, sediment trap dataExpand
Eddy-mediated biological productivity in the Bay of Bengal during fall and spring intermonsoons
The signature of cold-core eddies and their role in altering the biological productivity of the Bay of Bengal was examined using two recent sets of hydrographic data collected along the central andExpand
Tularaemia: A challenging zoonosis
A review of the main features of the Francisella tularensis agent, its biology, immunology and epidemiology, with special focus on zoonotic aspects of the disease, as tularaemia outbreaks in human populations have been frequently associated with disease in animals. Expand
The hard-tick fauna of mainland Portugal (Acari: Ixodidae): an update on geographical distribution and known associations with hosts and pathogens
This work is an updated revision of the available information on Portuguese ixodid tick species. It includes data on tick biology, ecology, taxonomy and host/pathogen-associations. The current listExpand
Genotypic evaluation of rickettsial isolates recovered from various species of ticks in Portugal.
For the first time in Portugal a widely distributed spectrum of spotted fever group rickettsia was found among potential vector species stressing the need to determine their potential for human and domestic animals infection. Expand
Coinoculation of Borrelia spp. with Tick Salivary Gland Lysate Enhances Spirochete Load in Mice and Is Tick Species–Specific
Protein profile analysis indicated at least 5 major protein differences between I. scapularis and I. ricinus SGL, which can possibly account for this specific tick–spirochete interaction. Expand
Genotypic diversity of clinical Coxiella burnetii isolates from Portugal based on MST and MLVA typing.
A genotypic diversity of C. burnetii consistent with a non-outbreak situation was identified, and the involvement of different genotypes in acute and chronic Q fever was found, linking one of the chronic genotypes to goats from the eastern region of the country. Expand
Serological and molecular survey of Anaplasma species infection in dogs with suspected tickborne disease in Portugal
Direct amplicon sequencing failed to identify active A phagocytophilum infections, but revealed the presence of Anaplasma platys DNA in the PCR-positive animals. Expand
Role of the Lizard Teira dugesii as a Potential Host for Ixodes ricinus Tick-Borne Pathogens
ABSTRACT PCR screening of ticks and tissue samples collected from 151 Teira dugesii lizards seems to indicate a potential role of this lizard species in the maintenance and transmission cycle of someExpand
Detection of Ehrlichia canis by polymerase chain reaction in dogs from Portugal.
The 16S rRNA gene of E. canis was detected by the polymerase chain reaction (PCR) in 12/55 (22%) of dogs with suspected tick-borne disease in the Algarve region in Portugal. Expand
