The bla NDM-1 carrying IncA/C2 plasmid underlies structural alterations and co-integrate formation in vivo

Antimicrobial Agents and Chemotherapy publish this investigation article


In 2012, a carbapenemase-producing Salmonella (S.) Corvallis carrying a bla NDM-1 multi-resistance IncA/C2 plasmid, apart from IncHI2 and ColE-like plasmids, was detected in a wild bird in Germany. In recent broiler chicken infection study, we observed transfer of this bla NDM-1-carrying IncA/C2 plasmid to other Enterobacteriaceae Here, we focused on the stability of this plasmid and gained insight into type and frequency of its structural alterations after an in vivo passage in a broiler infection study… Read more

Detección molecular de Trypanosoma cruzi en pelo de ratón infectado experimentalmente

Degree Final Project defended by Silvia Díaz Franchy


Trypanosoma cruzi es el parásito protozoo causante de la enfermedad de Chagas, que afecta entre 6 y 8 millones de personas. Es una enfermedad transmitida principalmente por insectos de la familia Reduviidae, aunque también se puede transmitir por vía oral, mediante transfusiones o vía congénita. Se trata de una enfermedad infradiagnosticada en Europa, siendo España el país europeo con mayor número de personas afectadas por T. cruzi. En los países endémicos los animales salvajes suponen uno de los principales reservorios, haciendo el manejo y obtención de muestras difícil. Por tanto, se ha cons… Read more

A pathological study of Leishmania infantum natural infection in European rabbits (Oryctolagus cuniculus) and Iberian hares (Lepus granatensis)

Investigation article published in Transboundary and Emerging Diseases


In this study, we describe the pathology of Leishmania infantum infection in naturally infected wild Leporidae and compare diagnosis of infection using histopathology, direct fluorescent antibody (DFA) assay, immunofluorescence antibody test (IFAT), and quantitative real‐time PCR (qPCR). Tissues were analysed from 52 European rabbits (Oryctolagus cuniculus) and 7 Iberian hares (Lepus granatensis) from the Community of Madrid (Spain). Our results show that L. infantum infection is associated with only minimal histopathological lesions and that L. infantum amastigotes can be detected by DF… Read more

Desarrollo y puesta a punto de una técnica de base inmunológica para la detección conjunta de ricina y aglutinina

Presentation by Virginia Colmena García to obtain the Master in Disaster Management


La ricina es una de las toxinas más potentes conocidas, que se encuentra en la semilla del ricino (Ricinus communis). El Centro para el Control y la Prevención de Enfermedades de Estados Unidos (CDC) la clasifica como posible arma biológica. Existen diferentes métodos para la detección de esta proteína, siendo la técnica inmunológica ELISA, especialmente el ELISA tipo sándwich, la que está considerada como la técnica más robusta para su análisis, ya que es sensible, específica, con límites de detección de picogramos y fácil de realizar. No obstante, el reto está en poder diferenciar la ricina … Read more

Circulation of a novel strain of dolphin morbillivirus (DMV) in stranded cetaceans in the Mediterranean Sea

Investigation article published in Scientific reports


Dolphin morbillivirus (DMV) has been responsible for several outbreaks of systemic infection and has resulted in cetacean strandings in the Mediterranean. In August-October 2016, seven striped dolphins (Stenella coeruleoalba) stranded on the Sicilian coastline (Italy) tested positive for DMV. Tissue samples from brain, lung, pulmonary lymph nodes, heart, spleen, liver, stomach, intestine, kidneys and urinary bladder, as well as blowhole swabs, were collected during necropsy for molecular diagnostics and pathology studies. Extracted tissue RNA was screened for DMV by real-time reverse transcrip… Read more

Nucleotide sequence variations may be associated with virulence of deformed wing virus

Investigation published in Apidologie


Western honey bees (Apis mellifera) are key players in crop pollination and in the maintenance of global biodiversity. Their viability is threatened by Varroa destructor, which acts as a vector of the deformed wing virus (DWV). Several genetic DWV variants have been reported, but it is unclear whether their virulence differs. We examined the prevalence of V. destructor and DWV as well as bee health in two colonies over 21 months and then characterizing DWV variants from each colony using phylogenetics. Colony H showed no signs of disease or mortality, and DWV sequence from this colony clustere… Read more

Evaluation of the health status of the main aquaculture species in Papua New Guinea

PhD Thesis defense by Ruth García Gómez at the VISAVET Centre of the Complutense University of Madrid


The aquaculture sector has been strongly promoted y developed in a technically feasible, economically viable y long-term sustainable way in the Pacific Region for more than two decades. Numerous international, intergovernmental, regional agencies y programs have focused their economic y human efforts on the sustainable development of this sub-sector (within the fisheries sector) in the Pacific, with limited results y not many successful stories. The Oceania region remains the world`s least developed region in the world`s aquaculture sector, with some exceptions such as Australia y New Zealy, f… Read more

Animal welfare epidemiology: how epidemiologists help to improve the welfare of animals

Conference in Seminarios VISAVET 2019


Animal welfare epidemiology is a rapidly growing area in veterinary science. Epidemiology offers the methodology to quantify the welfare impact of individual diseases on the animals, compare the impact among different diseases and facilitate disease prioritisation. Animal welfare science extends the focus of veterinary epidemiology − animal health – to a broader sense of animal well-being. The concept of animal welfare epidemiology is then demonstrated by the epidemiological studies on the impact of feline obesity on the survival and health in cats, follow by Welfare-Adjusted Life Year (… Read more

Effect of litter aggregation and pooling on detection of porcine reproductive and respiratory virus in piglet processing fluids

Investigation published in Journal of Veterinary Diagnostic Investigation


A sampling technique has been validated to monitor porcine reproductive and respiratory syndrome virus 2 (PRRSV-2) using the serosanguinous exudate known as processing fluids (PFs) that accumulate from tissues obtained during tail docking and castration. PFs are an aggregate sample of large numbers of piglets and litters. However, little is known about the effect of litter aggregation on the ability of PCR to correctly classify an aggregated PF sample as positive. We evaluated both the effect of litter aggregation and of PF pooling on PCR detection. We estimated that aggregation of at least 50… Read more

The possible route of introduction of bluetongue virus serotype 3 into Sicily by windborne transportation of infected Culicoides spp

Investigation article published in Transboundary and Emerging Diseases


In October 2017, the first outbreak of bluetongue virus serotype 3 (BTV-3) began in Italy, specifically in western Sicily. The route of entrance remains unclear, although since 2016 the same strain had been circulating only 150 km away, on the Tunisian peninsula of Cape Bon. The present analysis assessed the feasibility that wind could have carried BTV-3-infected Culicoides spp. from Tunisia to Sicily. An advection-deposition-survival (ADS) model was used to estimate when and where Culicoides spp. were likely to be introduced prior to the first BTV-3 report in Italy. Additionally, the Hybrid S… Read more

Potentially human-virulent Vibrio vulnificus isolates from diseased great pompano (Trachinotus goodei)

Transboundary and Emerging Diseases publish this investigation article


Vibrio vulnificus is an opportunistic human pathogen responsible for the majority of seafood-associated deaths worldwide and is also a relevant fish pathogen for the aquaculture industry. In addition to infections in aquatic livestock, Vibrio vulnificus also represents a risk to aquarium animals. For the first time, this work describes an important mortality outbreak in Trachinotus goodei in a zoo aquarium, with the isolation of Vibrio vulnificus (Vv) from the internal organs of the diseased fish. The isolates were identified by MALDI-TOF MS, serotyped and characterized by PFGE. Although the i… Read more
