Identification of blood meals in field captured sand flies by a PCR-RFLP approach based on cytochrome b gene
Leishmaniasis is a vector-borne disease transmitted byphlebotominesand flies. Information about blood meal preferences in sand flies is essential to understand the epidemiology of the diseaseto adopt control measures.In ...
Gut bacterial community of the xylophagous cockroaches Cryptocercus punctulatus and Parasphaeria boleiriana
Cryptocercus punctulatus and Parasphaeria boleiriana are two distantly related xylophagous and subsocial cockroaches. Cryptocercus is related to termites. Xylophagous cockroaches and termites are excellent model organisms ...
Relationship between membrane vesicles, extracellular ATP and biofilm formation in Antarctic Gram-negative bacteria
Biofilms offer a safe environment that favors bacterial survival; for this reason, most pathogenic and environmental bacteria live integrated in biofilm communities. The development of biofilms is complex and involves many ...
Ciclo vital y posicion sistematica de Jaagiella alpicola Vischer (Chlorophyceae)
Jaagiella alpicola fue aislada de suelos del Cap Norfeu (Gerona) mediante cultivos de enriquecimiento. Las células vegetativas son uninucleadas y contienen un cloroplasto parietal sin pirenoide. La reproducción asexual se ...
La funció dels pins en el paisatge dels Països Catalans
Un viatger que resseguís els Països Catalans d'un cap a l'altre, sense idees preconcebudes, obtindria la impressió d'haver recorregut una terra bàsicament de pinedes. Si no de Salses a Guardamar, almenys de Figueres a la ...
Echinococcus multilocularis (Cestoda, Cyclophyllidea, Taeniidae): functional ultrastructure of the penetration glands and nerve cells within the oncosphere
The fine structure of the infective hexacanths of Echinococcus multilocularis was examined with particular emphasis on the functional ultrastructure of penetration glands and nerve cells directly involved in the mechanism ...
Immunosuppression and Chagas disease: a management challenge
Immunosuppression, which has become an increasingly relevant clinical condition in the last 50 years, modifies the natural history of Trypanosoma cruzi infection in most patients with Chagas disease. The main goal in this ...
Downregulation of Tomato STEROL GLYCOSYLTRANSFERASE 1 Perturbs Plant Development and Facilitates Viroid Infection
Potato spindle tuber viroid (PSTVd) is a plant pathogen naturally infecting economically important crops such as tomato (Solanum lycopersicum). Here, we aimed to engineer tomato plants highly resistant to PSTVd and developed ...
Ultrastructural evidence for completion of the entire miracidial maturation in intrauterine eggs of the digenean Brandesia turgida (Brandes, 1888) (Plagiorchiida: Pleurogenidae)
Results of this TEM study provide ultrastructural evidence that miracidial morphogenesis is fully completed within the intrauterine eggs situated in the most posterior uterine regions of the pleurogenid trematode Brandesia ...
Autochthonous and imported tegumentary leishmaniasis in Catalonia (Spain): Aetiological evolution in the last four decades and usefulness of different typing approaches based on biochemical, molecular and proteomic markers
Leishmaniasis is a transmissible disease caused by Leishmania protozoa. Spain is endemic for both visceral and cutaneous leishmaniasis, the autochthonous aetiological agent being Leishmania infantum. Around the world, the ...
Structural characterization and identification of cyclic lipopeptides produced by Bacillus methylotrophicus DCS1 strain
Bacillus methylotrophicus DCS1 strain was isolated from diesel contaminated soil and screened for its ability to produce biosurfactants; it was found effective for the production of surface active molecules. The structural ...
Cholinesterase Inhibition Activity, Alkaloid Profiling and Molecular Docking of Chilean Rhodophiala (Amaryllidaceae)
Amaryllidaceae plants are the commercial source of galanthamine, an alkaloid approved for the clinical treatment of Alzheimer's disease. The chemistry and bioactivity of Chilean representatives of Rhodophiala genus from ...
Plant sources of galanthamine: phytochemical and biotechnological aspects.
Galanthamine, an Amaryllidaceae type alkaloid, is an AChE inhibitor marketed as a hydrobromide salt for the treatment of Alzheimer's disease, poliomyelitis and other neurological diseases. Although the chemical synthesis ...
Isoenzymatic characterization of Phlebotomus ariasi and P. perniciosus of canine leishmaniasis foci from Eastern Pyrenean regions and comparison with other populations from Europe.
An entomological survey was carried out in 2007 in two Pyrenean counties of Lleida province (northeastern Spain), where cases of autochthonous canine leishmaniasis have been recently reported. Phlebotomus ariasi and P. ...
Leishmaniosis caused by Leishmania infantum in ferrets: Update review
Leishmaniosis in domestic ferrets (Mustela putorius furo) is a disease caused by Leishmania infantum, a parasite transmitted through the bite of an infected female phlebotomine sand fly. Among vertebrates, the dog is the ...
Sporotrichoid dissemination of cutaneous leishmaniasis possibly triggered by a diagnostic puncture
Case report: A 31 year old Spanish woman attended Hospital Clinic in Barcelona in August 2018, after working in La Paz (Bolivia) for six months. She remembered an insect bite on her right thigh, during a trip to Beni ...
HIV-positive women have higher prevalence of comorbidites and anticholinergic burden. Assessment of the HIV positive population from Menorca (Balearic Islands)
Currently, the management of comorbidities and polypharmacy in HIV-infected patients requires a coordinated action, with special focus on gender differences. Observational, cross-sectional study was conducted to study the ...
Global spread of helminth parasites at the human - domestic animal - wildlife interface
Changes in species distributions open novel parasite transmission routes at the human-wildlife interface, yet the strength of biotic and biogeographical factors that prevent or facilitate parasite host shifting are not ...
