Presence and distribution of honeybee viruses in spanish colonies
Comunicación oral en BEE DOC workshop-Diagnostics in honeybees: from sampling to data analyses
In the recent years the number of honeybees Apis mellifera has decreased dramatically in a worldwide phenomena called Collony Collapse Disorder (CCD).The direct importance of the honeybee productions and the indirect effect of this insect as a pollinator of the main crops in USA and UE, where Spain is the first honey producer, has provided numerous studies of CCD. However, the causes of this syndrome are still unknown, although most authors point a multifactorial problem where pathogens play an important role. Among which, viruses are the most unknown and their presence in CCD events alone or …

Isolation of Enterococcus hirae from suckling rabbits with diarrhoea
Artículo de investigación publicado en The Veterinary Record
Enterococci are commensal microorganisms of the intestinal tract of human beings and animals, and can also be found in a wide range of environments (Klein 2003, Donskey 2004). Enterococci were considered to be non-pathogenic for many years, but several species, most notably Enterococcus faecium and Enterococcus faecalis, have emerged as human pathogens, and are currently considered to be among the most important nosocomial pathogens (Murray and Weinstock 1999). Enterococci are also responsible for causing various diseases in a number of animal species (Rogers and others 1992, Cheon and Chae 19…

Polyclonal Aspergillus fumigatus infection in captive penguins
Investigación publicada en Veterinary Microbiology
Aspergillus fumigatus is a known opportunistic pathogen of penguins. Most reports of penguin aspergillosis have focused on clinical, histopathological and microbiological findings. The molecular characterization of A. fumigatus isolates involved in invasive infections in penguins has yet to be addressed. The aim of this work was to study the possible coexistence of different A. fumigatus genotypes in five clinical cases of invasive aspergillosis in captive penguins. Differences in other relevant characteristics of the isolates, including mating type and invasiveness, were also considered.

Identifying areas for infectious animal disease surveillance in the absence of population data: highly pathogenic avian influenza in wild bird populations of Europe
Artículo de investigación publicado en Preventive Veterinary Medicine
A large number (n=591) of H5N1 highly pathogenic avian influenza virus (HPAIV) outbreaks have been reported in wild birds of Europe from October 2005 through January 2009. Consequently, prevention and control strategies have been implemented in response to the outbreaks and considerable discussion has taken place regarding the need for implementing surveillance programs in high-risk areas with the objective of early detecting and preventing HPAIV epidemics. However countries ability to define the temporal and spatial extension of the high risk areas has been impaired by the lack of information…

First Case of Highly Pathogenic Avian Influenza in Poultry in Spain
Transboundary and Emerging Diseases publica este artículo de investigación
Summary In October 2009, highly pathogenic avian influenza virus (HPAIV) was isolated for the first time in poultry in Spain. Sequencing analysis revealed that it was an H7N7 HPAIV. The progenitors of H7 HPAIV strains involved in recent European poultry outbreaks were simultaneously circulating in wild birds. The infected Spanish farm is located close to a reservoir abundant in wild birds. Epidemiological investigation found no links to other poultry holdings and those located in the control area were negative for AIV. Previous spatial risk analyses had identified the area where the infected h…

A simulation model for the potential spread of foot-and-mouth disease in the Castile and Leon region of Spain
Artículo de investigación publicado en Preventive Veterinary Medicine
A spatial stochastic model was used to simulate the spread of a foot-and-mouth disease (FMD) epidemic in the Castile-and-Leon (CyL) region of Spain. The model was fitted using information available on premises demographics and on assumptions for animal movements, indirect contacts, and airborne exposure. Control measures dictated by Spanish and European Union regulations constituted a reference strategy to which six alternative control strategies were compared. For the reference strategy, the median (95% PI) numbers of infected, depopulated, and quarantined premises were 141 (2-1099), 164 (4-1…

Presence of herpesvirus in striped dolphins stranded during the cetacean morbillivirus epizootic along the Mediterranean Spanish coast in 2007
Archives of Virology publica este artículo de investigación
A screening for herpesvirus (HV) was carried out using a tissue bank obtained from the cetacean morbillivirus (CeMV) mortality episode that occurred along the Mediterranean Spanish coast in 2007. A total of 14 cetaceans, including six long-finned pilot whales and eight striped dolphins, were studied using histopathology and molecular analysis to detect HV and CeMV. In five of the eight dolphins (62.5%) infected with CeMV, eight novel HV sequences were also detected. No HV lesions were found in any of the coinfected dolphins, which may indicate that HV did not contribute to the mortality in the…
