La producción de carne de ovino y caprino en Canarias aumenta un 19,5% entre 2015 y 2017

Apoyo a las Producciones Agrarias de Canarias

La producción de carne de ovino y caprino en Canarias se ha incrementado un 19,5 por ciento entre 2015 y 2017, debido principalmente a la modificación introducida en el Programa Comunitario de Apoyo a las Producciones Agrarias de Canarias (Posei) propuesta por el Ejecutivo canario, que prima la producción sobre otros aspectos…

Testing the Role of Multicopy Plasmids in the Evolution of Antibiotic Resistance

Journal of visualized experiments : JoVE publish this investigation article

Multicopy plasmids are extremely abundant in prokaryotes but their role in bacterial evolution remains poorly understood. We recently showed that the increase in gene copy number per cell provided by multicopy plasmids could accelerate the evolution of plasmid-encoded genes. In this work, we present an experimental system to test the ability of multicopy plasmids to promote gene evolution. Using simple molecular biology methods, we constructed a model system where an antibiotic resistance gene can be inserted into Escherichia coli MG1655, either in the chromosome or on a multicopy plasmid. We … Read more

The use of serological tests in combination with the intradermal tuberculin test maximizes the detection of tuberculosis infected goats

Veterinary Immunology and Immunopathology publish this investigation article

The diagnosis of tuberculosis (TB) in goats is based mainly on the single and comparative intradermal tuberculin (SIT and CIT) tests and, exceptionally, on the interferon-gamma (IFN-γ) assay, however they are not perfect in terms of sensitivity and specificity. Nevertheless, various serological assays that provide a potential cost-effective approach for the control of TB are also available or under development, and a variety of results have been reported regarding the ability of these tests to detect infected animals, particularly in the early stages of infection. In the present study, S… Read more

Streptococcus penaeicida sp. nov., isolated from a diseased farmed Pacific white shrimp (Penaeus vannamei)

Investigation published in International Journal of Systematic and Evolutionary Microbiology

Strain CAIM 1838T, isolated from the hepatopancreas of a cultured diseased Pacific white shrimp (Penaeusvannamei), was subjected to characterization by a polyphasic taxonomic approach. On the basis of 16S rRNA gene sequence analysis, strain CAIM 1838T was most closely related to Streptococcus bovimastitidis 99.3 % and to other species of the Pyogenes clade of Streptococcus with lower similarity values. Average nucleotide identity values and the genome-to-genome distance of strain CAIM 1838T, as compared with the type strains, confirmed the separate species status with closely related spe… Read more

Plasmids carrying antimicrobial resistance genes in Enterobacteriaceae

Investigation published in The Journal of Antimicrobial Chemotherapy

Bacterial antimicrobial resistance (AMR) is constantly evolving and horizontal gene transfer through plasmids plays a major role. The identification of plasmid characteristics and their association with different bacterial hosts provides crucial knowledge that is essential to understand the contribution of plasmids to the transmission of AMR determinants. Molecular identification of plasmid and strain genotypes elicits a distinction between spread of AMR genes by plasmids and dissemination of these genes by spread of bacterial clones. For this reason several methods are used to type the plasmi… Read more

Gaps in African swine fever: Analysis and priorities

Investigation published in Transboundary and Emerging Diseases

African swine fever (ASF) causes greater sanitary, social and economic impacts on swine herds than many other swine diseases. Although ASF was first described in 1921 and it has affected more than fifty countries in Africa, Europe and South America, several key issues about its pathogenesis, immune evasion and epidemiology remain uncertain. This article reviews the main characteristics of the causative virus, its molecular epidemiology, natural hosts, clinical features, epidemiology and control worldwide. It also identifies and prioritizes gaps in ASF from a horizontal point of view encompassi… Read more

Multicopy plasmids allow bacteria to escape from fitness trade-offs during evolutionary innovation

Nature Ecology & Evolution publish this article

Understanding the mechanisms governing innovation is a central element of evolutionary theory. Novel traits usually arise through mutations in existing genes, but trade-offs between new and ancestral protein functions are pervasive and constrain the evolution of innovation. Classical models posit that evolutionary innovation circumvents the constraints imposed by trade-offs through genetic amplifications, which provide functional redundancy. Bacterial multicopy plasmids provide a paradigmatic example of genetic amplification, yet their role in evolutionary innovation remains largely unexplored… Read more
