Sequencing of modern Lepus VDJ genes shows that the usage of VHn genes has been retained in both Oryctolagus and Lepus that diverged 12 million years ago

Investigation article published in Immunogenetics

Among mammals, the European rabbit (Oryctolagus cuniculus) has a unique mechanism of generating the primary antibody repertoire. Despite having over 200 VH genes, the VH1 gene, the most D-proximal VH gene, is used in 80-90 % of VDJ rearrangements, while the remaining 10-20 % is encoded by the VHn genes that map at least 100 Kb upstream of VH1. The maintenance of the VHn genes usage in low frequency in VDJ rearrangements has been suggested to represent a relic of an ancestral immunologic response to pathogens. To address this question, we sequenced VDJ genes for another leporid, genus Lepus, wh… Read more

Multiclonal dispersal of KPC genes following the emergence of non-ST258 KPC-producing Klebsiella pneumoniae clones in Madrid, Spain

Investigation published in The Journal of Antimicrobial Chemotherapy

OBJECTIVES: To analyse the ongoing epidemiology of KPC-producing Enterobacteriaceae after a non-ST258 KPC-3-producing Klebsiella pneumoniae outbreak in a university hospital in Madrid, Spain. METHODS: Enterobacterial isolates (one per patient based on bacterial identification and typing patterns) with carbapenem MICs higher than the EUCAST epidemiological cut-off values, a positive modified Hodge test and carbapenem/boronic acid combination disc test results were studied (16 March 2010 to 31 January 2012) and compared with KPC-producing isolates previously described in our institution (Sept… Read more

Global transcriptome analysis of Lactococcus garvieae strains in response to temperature

Investigation article published in PLoS ONE

Lactococcus garvieae is an important fish and an opportunistic human pathogen. The genomic sequences of several L. garvieae strains have been recently published, opening the possibility of global studies on the biology of this pathogen. In this study, a whole genome DNA microarray of two strains of L. garvieae was designed and validated. This DNA microarray was used to investigate the effects of growth temperature (18°C and 37°C) on the transcriptome of two clinical strains of L. garvieae that were isolated from fish (Lg8831) and from a human case of septicemia (Lg21881). The transcriptome pro… Read more

Splitting of a prevalent Mycobacterium bovis spoligotype by Variable Number Tandem Repeat Typing reveals high heterogeneity in an evolving clonal group

Journal of Clinical Microbiology publish this investigation article

Mycobacterium bovis populations in countries with persistent bovine tuberculosis usually show a prevalent spoligotype with a wide geographical distribution. This study applied Mycobacterial Interspersed Repetitive Unit (MIRU) - Variable Number Tandem Repeat (VNTR) typing to a random panel of 115 M. bovis isolates representative of the most frequent spoligotype in the Iberian Peninsula, SB0121. VNTR typing targeted nine loci: ETR-A (alias VNTR2165), ETR-B (VNTR2461), ETR-D (MIRU4, VNTR580), ETR-E (MIRU31, VNTR3192), MIRU26 (VNTR2996), QUB11a (VNTR2163a), QUB11b (VNTR2163b), QUB26 (VNTR4052) and… Read more

The effect of different isolation protocols on detection and molecular characterization of Campylobacter from poultry

Investigation article published in Letters in Applied Microbiology

We determined whether different methods to isolate Campylobacter (including the ISO standard 10272:2006-1) affected the genotypes detectable from poultry, at three points during slaughter: caecal content, neck skin and meat. Carcasses from 28 independent flocks were thus sampled (Subset A). In addition, ten neck skin samples from four flocks, ten caecal samples from ten different flocks and ten unrelated meat samples obtained from local supermarkets were collected (Subset B). Campylobacter was isolated using eight different protocols: with and without enrichment using Bolton broth, Preston bro… Read more

Cattle drive Salmonella infection in the wildlife-livestock interface

Investigation article published in Zoonoses and Public Health

The genus Salmonella is found throughout the world and is a potential pathogen for most vertebrates. It is also the most common cause of food-borne illness in humans, and wildlife is an emerging source of food-borne disease in humans due to the consumption of game meat. Wild boar is one of the most abundant European game species and these wild swine are known to be carriers of zoonotic and food-borne pathogens such as Salmonella. Isolation of the pathogen, serotyping and molecular biology are necessary for elucidating epidemiological connections in multi-host populations. Although disease mana… Read more

Situación actual de la fiebre Q: diagnóstico, legislación y medidas de vigilancia y control

New article published in Tierras. Caprino

La Fiebre Q es una enfermedad altamente contagiosa causada por Coxiella burnetii, una bacteria intracelular que puede infectar un amplio espectro de especies animales (siendo los rumiantes domésticos los principales reservorios) y al hombre, lo que la convierte en una zoonosis y por tanto en un problema de Salud Pública. En los rumiantes domésticos los problemas causados por la enfermedad son consecuencia principalmente de las alteraciones reproductivas a las que ésta da lugar, pudiendo ocasionar importantes pérdidas económicas en las explotaciones afectadas. Las alteraciones reproductivas más… Read more

Rickettsiosis: actualización

New article published in Profesión Veterinaria

Las enfermedades zoonósicas, las transmitidas entre animales vertebrados y humanos, son un grave problema para la Sanidad Pública a nivel mundial. De hecho, casi dos tercios de los patógenos humanos son zoonósicos. Las rickettsiosis, enfermedades causadas por bacterias de diferentes especies y subespecies del género Rickettsia, son algunas de las zoonosis transmitidas por vectores conocidas desde más antiguo. Actualmente son consideradas enfermedades emergentes y su distribución es mundial. Sin embargo, son "desconocidas" para una gran mayoría de la población incluidos profesionales sanitarios… Read more
