First report of colistin-resistant KPC-2 producing ST258-Klebsiella pneumoniae in Spain
Investigación publicada en Enfermedades Infecciosas y Microbiología Clínica
The rapid spread of Klebsiella pneumoniae carbapenemases (KPCs) in the last years represents a serious public health threat. KPCs have a great potential for spread due to their location on mobile genetic elements that are horizontally transferred and associated with widespread clones.1 Many KPC producing K. pneumoniae isolates are associated to a single sequence type (ST)258, a clonal lineage that has been causing epidemics of great proportions in various regions of USA, Israel, Greece and recently in other European countries.2, 3 Organisms carrying carbapenemases usually harbours resistance d…

Genetic analysis of Streptococcus suis isolates from wild rabbits
Veterinary Microbiology publica este artículo de investigación
This work aims to investigate the presence of Streptococcus suis in wild rabbits. A total of 65 S. suis isolates were recovered from 33.3% of the wild rabbits examined. Most isolates (86.2%) belong to genotype cps9. These isolates were further characterized by pulsed field gel electrophoresis (PFGE), multilocus sequence typing (MLST) and virulence genotyping. Overall, S. suis exhibited a low genetic diversity. Only 5 genetic profiles were obtained by PFGE and most isolates (71.4%) were included in two pulsotypes that were also widely distributed among the wild rabbit population. MLST analysis …

Detección precoz de mortalidad en producciones avícolas empleando termografía de alta resolución
Comunicación oral en VII Congreso Ibérico de Agroingeniería y Ciencias Hortícolas
Las modernas instalaciones para la producción avícola de puesta agrupan un muy elevado número de individuos en baterías de jaulas. Esta disposiciónsupone un reto de cara al control de temperaturas dentro de las naves, para garantizar que éstas se encuentren dentro del intervalo de confort térmico de los animales (12-24°C en el caso de ponedoras). Asimismo, la detección temprana de posibles individuos con problemas o muertos resulta una tarea imprescindible para asegurar el bienestar de los restantes animales. La supervisión continúa y multidistribuida de la temperatura en los gallineros puede…

Indigenous and acquired modifications in the aminoglycoside binding sites of Pseudomonas aeruginosa rRNAs
Investigación publicada en RNA Biology
Aminoglycoside antibiotics remain the drugs of choice for treatment of Pseudomonas aeruginosa infections, particularly for respiratory complications in cystic-fibrosis patients. Previous studies on other bacteria have shown that aminoglycosides have their primary target within the decoding region of 16S rRNA helix 44 with a secondary target in 23S rRNA helix 69. Here, we have mapped P. aeruginosa rRNAs using MALDI mass spectrometry and reverse transcriptase primer extension to identify nucleotide modifications that could influence aminoglycoside interactions. Helices 44 and 45 contain indigeno…

Development of a suspension microarray for the genotyping of African Swine Fever Virus targeting the SNPs in the c-terminal end of the p72 gene region of the genome
Investigación publicada en Transboundary and Emerging Diseases
African swine fever virus (ASFV) causes one of the most dreaded transboundary animal diseases (TADs) in Suidae. African swine fever (ASF) often causes high rates of morbidity and mortality, which can reach 100% in domestic swine. To date, serological diagnosis has the drawback of not being able to differentiate variants of this virus. Previous studies have identified the 22 genotypes based on sequence variation in the C-terminal region of the p72 gene, which has become the standard for categorizing ASFVs. This article describes a genotyping assay developed using a segment of PCR-amplified geno…
