Evaluation of the use of a needle-free injection syringe as a cause of non-specific reactions in the intradermal tuberculin test used for the diagnosis of bovine tuberculosis
Artículo de investigación publicado en Research in Veterinary Science
The objective of the study was to elucidate whether the use of the needle-free Dermojet syringe, which is based on a high pressure inoculation and is used to inject tuberculin in cattle in several countries, may, in itself, cause skin reactions that can be interpreted as positive reactions to the intradermal tests that are not, in fact, related to the real infection status of the animals.
Forty-four cattle from an officially tuberculosis-free (OTF) herd were selected, and four single intradermal tuberculin (SIT) tests were performed on each animal, two on each side of the neck. Three differen…

Temporal analysis of the interference caused by paratuberculosis vaccination on the tuberculosis diagnostic tests in goats
Artículo de investigación publicado en Preventive Veterinary Medicine
Vaccination against paratuberculosis (PTB) in goats is a cost-effective control strategy, and is also effective as regards preventing the onset of clinical cases. However, it causes interference in the diagnostic tests used in the control of tuberculosis (TB). A group of 99 goats from a herd with no history of TB or PTB infection was vaccinated against PTB at seven months of age. They then underwent consecutive intradermal tests [single (SIT) and comparative (CIT) intradermal tuberculin tests), interferon-gamma release assays (IGRA) and two serological tests (p22_CE and DR-ELISA) every three m…

Genetic dissection of the BRCA2 promoter and transcriptional impact of DNA variants
Breast cancer research and treatment publica este artículo de investigación
Purpose
Promoter mutations may affect transcription and can be associated with human diseases. However, the promoters of the breast cancer (BC) genes are not regularly screened. Our goal was to investigate the BRCA2 promoter in order to study a possible correlation between impaired transcription and disease.
Methods
The proximal and core promoter of the BRCA2 gene was sequenced in 95 high-risk BC patients. A BRCA2-promoter insert [− 938 to + 312 from the transcription start site (TSS)] was generated and cloned into the firefly luciferase vector pGL4.10. Promoter variants and del…

Testing the Role of Multicopy Plasmids in the Evolution of Antibiotic Resistance
Journal of visualized experiments : JoVE publica este artículo de investigación
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 …

The use of serological tests in combination with the intradermal tuberculin test maximizes the detection of tuberculosis infected goats
Veterinary Immunology and Immunopathology publica este artículo de investigación
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…

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

Plasmids carrying antimicrobial resistance genes in Enterobacteriaceae
Investigación publicada en 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…

Gaps in African swine fever: Analysis and priorities
Investigación publicada en 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…

Multicopy plasmids allow bacteria to escape from fitness trade-offs during evolutionary innovation
Artículo de divulgación publicado en Nature Ecology & Evolution
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…
