The main goal of ex situ conservation programs is to improve the chances of long term survival of natural populations by founding and managing captive colonies that can serve as a source of individuals for future reintroductions or to reinforce existing populations. The degree in which a captive breeding program has captured the genetic diversity existing(More)
Previous studies on Leishmania infantum and the canine immune response are derived mainly from short-term studies. To date, there have been no longitudinal studies that perform a serial analysis of the intensity of infection in conjunction with immunological parameters and clinical signs in Leishmania-infected dogs. For this purpose, six dogs were infected(More)
Vaccination of dogs, the domestic reservoir of Leishmania infantum, is the best method for controlling zoonotic visceral leishmaniasis. This strategy would reduce the incidence of disease in both the canine and, indirectly, the human population. Different vaccination approaches have been investigated against canine leishmaniasis (CaL) but to date there is(More)
The aims of the present study were to determine the prevalence of hemoplasmas in cats and dogs from the Barcelona area of Spain with the use of species-specific quantitative polymerase chain reaction (qPCR) assays and to evaluate any associations between hemoplasma infection, clinical presentation, and vector-borne infections. Blood samples from cats (191)(More)
BACKGROUND The historical classification of Demodex mites has been based on their hosts and morphological features. Genome sequencing has proved to be a very effective taxonomic tool in phylogenetic studies and has been applied in the classification of Demodex. Mitochondrial 16S rDNA has been demonstrated to be an especially useful marker to establish(More)
The aim of the present study is to highlight the advantages of real-time quantitative PCR intended to aid in the diagnosis and monitoring of canine leishmaniosis. Diagnosis of canine leishmaniosis is extremely challenging, especially in endemic areas, due to the diverse and non-specific clinical manifestations, and due to the high seroprevalence rate in(More)
Previous serological surveys have reported the presence of different organisms in cats from Spain but little reports exist about the exact identity of these organisms. The purpose of the study reported here was to assess the presence of DNA of several vector-borne infections in a population of cats from Barcelona area. One hundred blood samples obtained(More)
Blood samples from 153 dogs living in and around Barcelona were assayed for Leishmania infantum and Ehrlichia, Anaplasma, Rickettsia, Bartonella, Hepatozoon, Babesia and Theileria species by PCR amplification of DNA, and the amplicons obtained were sequenced. The prevalence of the infectious agents was L infantum (29.4 per cent), Ehrlichia and Anaplasma(More)
The aim of the present study was to determine the prevalence of Leishmania infantum infection in a wild reservoir host (Canis lupus) throughout an endemic area for the disease (Southern Europe). For that reason, the serum and peripheral blood samples of 33 captive wolves from the European Breeding of Endangered Species Programme (EEP) were analyzed using(More)
OBJECTIVES Risk for transmission of Leishmania infantum from blood products has been largely demonstrated in human and veterinary literature. Appropriate screening of canine blood donors is important especially in an endemic area such as Barcelona (Spain). The purpose of this study was to evaluate the presence of L infantum DNA parasites by real-time(More)
