Dietary profiles of wild carnivores and Blastocystis occurrence: The case of the endangered Iberian lynx (Lynx pardinus) and systematic review.

Recent molecular and metagenomic studies have revealed that the obligate anaerobic protist Blastocystis is found more prevalently and with higher subtype diversities in herbivore species than in carnivore species. However, information on wild carnivore species is scarce. Here, we investigated the presence of Blastocystis by molecular methods in fecal DNA samples of free-ranging and captive Iberian lynxes from Spain (n = 243) and Portugal (n = 30).

Occurrence and molecular genotyping of Giardia duodenalis and Cryptosporidium spp. in wild mesocarnivores in Spain.

There is a surprisingly scarce amount of epidemiological and molecular data on the prevalence, frequency, and diversity of the intestinal protozoan parasites Giardia duodenalis and Cryptosporidium spp. in wildlife in general and mesocarnivore species in particular. Consequently, the extent of the cyst/oocyst environmental contamination attributable to these wild host species and their potential implications for public veterinary health remain largely unknown.

LEISHMANIA INFANTUM INFECTION IN BENNETT'S WALLABIES (MACROPUS RUFOGRISEUS RUFOGRISEUS) IN A SPANISH WILDLIFE PARK.

Although dogs are the main reservoir for human Leishmania infantum infection, the disease has also been reported in other domestic and wild mammals. In 2011, a fatal case of naturally acquired leishmaniosis was described for the first time in a Bennett's wallaby (Macropus rufogriseus rufogriseus) kept in a wildlife park in Madrid (Spain). This study was designed to assess the infection status of twelve Bennett's wallabies in the same park one year after this incident.

Evaluation of five commercial methods for the extraction and purification of DNA from human faecal samples for downstream molecular detection of the enteric protozoan parasites Cryptosporidium spp., Giardia duodenalis, and Entamoeba spp.

High quality, pure DNA is required for ensuring reliable and reproducible results in molecular diagnosis applications. A number of in-house and commercial methods are available for the extraction and purification of genomic DNA from faecal material, each one offering a specific combination of performance, cost-effectiveness, and easiness of use that should be conveniently evaluated in function of the pathogen of interest. In this comparative study the marketed kits QIAamp DNA stool mini (Qiagen), SpeedTools DNA extraction (Biotools), DNAExtract-VK (Vacunek), PowerFecal DNA isolation (MoBio), and Wizard magnetic DNA purification system (Promega Corporation) were assessed for their efficacy in obtaining DNA of the most relevant enteric protozoan parasites associated to gastrointestinal disease globally.

Panobinostat as part of induction and maintenance for elderly patients with newly diagnosed acute myeloid leukemia: phase Ib/II panobidara study.

This phase Ib/II trial combined the pan-deacetylase inhibitor panobinostat with chemotherapy followed by panobinostat maintenance in elderly patients with newly diagnosed acute myeloid leukemia. Patients with prior history of myelodysplastic syndrome were excluded and 38 evaluable patients were included in the study (median age: 71 years; range: 65-83). Study patients received an induction with idarubicin (8 mg/m(2) iv days 1-3) plus cytarabine (100 mg/m(2) iv days 1-7) plus panobinostat po at escalating doses (days 8, 10, 12, 15, 17 and 19) that could be repeated in non-responding patients.

Detection and molecular characterization of Giardia duodenalis in children attending day care centers in Majadahonda, Madrid, Central Spain.

Infections by the protozoan enteroparasites Giardia duodenalis and Cryptosporidium spp are a major cause of morbidity in children attending day care facilities in developed countries. In this cross-sectional study, we aimed to estimate the occurrence and genotype frequencies of these pathogens in children attending day care centers in Majadahonda, Central Spain. To do so, single stool samples were obtained from 90 children and tested for the presence of G duodenalis and Cryptosporidium spp by conventional microscopy and immunochromatography.

Comparative study on the short term efficacy and adverse effects of miltefosine and meglumine antimoniate in dogs with natural leishmaniosis.

The aim of this study was to compare the efficacy and safety of oral administration of miltefosine (Milteforan) at 2 mg/kg/day for 28 days (Group M; n = 60) with a subcutaneous administration of meglumine antimoniate (Glucantime) at 50 mg/kg/12 h or at 100 mg/kg/day for 28 days (Group G; n = 59) in the treatment of canine leishmaniosis in dogs. Out of 119 dogs included in the study, 90 could be used for efficacy assessment and 112 for safety assessment. Treated dogs were followed up for 6 weeks, with re-checks every 14 days.

Detection of Toxoplasma gondii in cats by comparing bioassay in mice and polymerase chain reaction (PCR).

Feline toxoplasmosis can usually be diagnosed by serological and coprological methods. However, when the interpretation of results is difficult, it becomes necessary to rely on the direct detection of the parasite. In this study, samples of brain from 64 Toxoplasma-seropositive cats were subjected to direct detection of Toxoplasma gondii by bioassay in mice and nested-PCR.

Efficacy of Drontal Flavour Plus (50 mg praziquantel, 144 mg pyrantel embonate, 150 mg febantel per tablet) against Giardia sp in naturally infected dogs.

The therapeutic efficacy of praziquantel, pyrantel embonate and febantel (Drontal Flavour Plus) for three and five consecutive days was evaluated for treating naturally acquired giardiasis in dogs. In the study, 24 dogs naturally infected with Giardia were divided into three groups of eight dogs each. Dogs were treated at the recommended dosage for three or five consecutive days, and a control group remained untreated.

Hb La Coruña [beta38(C4)Thr --> Ile] is a new hemoglobin (Hb) variant that has an increased oxygen affinity. Clinically, this Hb leads to erythrocytosis. Hb La Coruña is an electrophoretically silent variant that can be detected by reversed phase high performance liquid chromatography (HPLC) and characterized by DNA sequencing.

Frequency of the C282Y and H63D mutations of the hemochromatosis gene (HFE) in a cohort of 1,000 neonates in Madrid (Spain).

For centuries in Europe, population movements have contributed to ethnic groups, cultures, and consequently, inheritance mixing. There are certain genetic diseases such as hereditary hemochromatosis whose distribution is directly related to the population movements. The objective of the present investigation was to determine the C282Y and H63D mutation frequency of the HFE gene in a cohort study of 1,000 neonates in the Community of Madrid (Spain), thus contributing to the HFE gene mutations distribution research in Europe and establishing the origin of the mutations in Spain.

A deletion of 11 bp (CD 131-134) in exon 3 of the beta-globin gene produces the phenotype of inclusion body beta-thalassemia.

Dominant inherited beta-thalassemias describe those beta-thalassemia variants that result in a thalassemia intermediate phenotype in individuals who have inherited only a single copy of the abnormal beta gene. This form of thalassemia is characterized by moderately severe anemia with jaundice and splenomegaly; it is also characterized by the presence of inclusion bodies in the red blood cell precursors and has, therefore, previously been referred to as inclusion body beta-thalassemia. We describe a case of inclusion body beta-thalassemia in a 51-year-old Spanish male caused by a deletion of 11 bp (CD 131-134) in exon 3 of the beta-globin gene.

A novel mutation of the alpha2-globin causing alpha(+)-thalassemia: Hb Plasencia [alpha125(H8)Leu--Arg (alpha2).

We describe, in a Spanish family with moderate microcytosis and hypochromia, a novel nondeletional alpha-thalassemia (thal) mutation localized on the alpha2-globin gene. DNA sequencing revealed a point mutation at codon 125 (CTG --> CGG) in the heterozygous state, that was confirmed by restriction analysis. The resulting variant, which causes a nondeletional alpha-thal, was named Hb Plasencia [alpha125(H8)Leu --> Arg (alpha2)] after the place of residence of the affected family.

[Association of hemoglobinopathy and alpha thalassemia. Study of 45 patients].

Background And Objective: Hemoglobin S (HbS) alpha-thalassemia together with ss-thalassemia and hemoglobins C, E and D are named common hemoglobinopathies. In this study, we analyzed the frequency of the association between alpha-thalassemia and HbS and its phenotypic expression.

Patients And Method: Since January 1995 to March 2003 we studied 83 cases of HbS, which were diagnosed by electrophoretic and chromatographic criteria.
