Construction of swine-specific CpG motif plasmid and the study of itsimmunostimulatory effects both in vitro and in vivo

Investigation article published in The Journal of Veterinary Medical Science

A swine-specific CpG motif enriched plasmid (pUC18-CpG) was constructed in this study. Its immunostimulant property was tested in vitro via lymphocyte transformation assay using swine peripheral blood mononuclear cells (PBMCs). The recombinant plasmid showed high Stimulation Index (SI) compared to the positive control (LPS). In a following animal vaccination-challenge experiment, pUC18-CpG was co-administered with a commercial swine FMD killed vaccine. Animals in the pUC18-CpG adjuvanted groups showed much higher antibody titers during the vaccination period… Read more

Global gene expression analysis in skin biopsies of European red deer experimentally infected with bluetongue virus serotypes 1 and 8

Veterinary Microbiology publish this investigation article

Bluetongue virus (BTV) is a double-stranded RNA virus transmitted by blood-feeding biting midges of the genus Culicoides to wild and domestic ruminants, causing high morbidity and variable mortality. The aim of this study was to characterize differential gene expression in skin biopsies of red deer (Cervus elaphus) hinds experimentally infected with BTV serotypes 1 and 8. Skin biopsies were collected from BTV-1 and BTV-8 experimentally infected and control hinds at 14 and 98 days post-infection (dpi). Global gene expression profile in response to BTV infection was characterized at 14dpi using … Read more

Microbial food safety in Ghana: a meta-analysis

Investigation published in Journal of Infection in Developing Countries

INTRODUCTION: Food safety is a crucial factor in the growth of developing countries worldwide. In this study, we present a meta-analysis of microbiological food safety publications from Ghana. METHODOLOGY: The search words "Ghana food safety", "Ghana food research", and "Ghana food bacteria" were used to search for microbiological food safety publications with related abstracts or titles in PubMed, published between 1997 and 2009. We obtained 183 research articles, from which we excluded articles concerning ready-to-eat microbial fermented foods and waterborne microorganisms as well as articl… Read more

Is Nestling Growth Affected by Nest Reuse and Skin Bacteria in Pied Flycatchers Ficedula hypoleuca?

Investigation published in Acta Ornithologica

Bacteria may colonize avian nests with unknown repercussions on nestling growth and health, although bacteria on nest materials may easily colonize nestling skin and growing feathers. Cavity nesters may have to build their nests on top of used nest materials, given restrictions on cavity availability. Nest reuse may favour bacterial colonization of nest materials and nestling skin and thereby affect nestling feather growth. To test these possibilities, we conducted a study of Pied Flycatchers Ficedula hypoleuca breeding in nest-boxes in central Spain. We left a sample of nest-boxes without rem… Read more

Effect of cattle on Salmonella carriage, diversity and antimicrobial resistance in free-ranging wild boar (Sus scrofa) in northeastern Spain

Investigation published in PLoS ONE

Salmonella is distributed worldwide and is a pathogen of economic and public health importance. As a multi-host pathogen with a long environmental persistence, it is a suitable model for the study of wildlife-livestock interactions. In this work, we aim to explore the spill-over of Salmonella between free-ranging wild boar and livestock in a protected natural area in NE Spain and the presence of antimicrobial resistance. Salmonella prevalence, serotypes and diversity were compared between wild boars, sympatric cattle and wild boars from cattle-free areas. The effect of age, sex, cattle presenc… Read more

Chryseobacterium viscerum sp. nov., isolated from diseased fish

Investigation article published in International Journal of Systematic and Evolutionary Microbiology

A taxonomic study was carried out on five Gram-staining-negative, catalase- and oxidase-positive, rod-shaped bacteria isolated from the gill and liver of five diseased rainbow trout. On the basis of 16S rRNA gene sequence analysis, the trout isolates belonged to the genus Chryseobacterium, exhibiting the highest similarity with Chryseobacterium oncorhynchi 701B-08T (98.9 % sequence similarity), C. ureilyticum F-Fue-04IIIaaaaT (98.6 %), C. indologenes ATCC 29897T (98.3 %), C. jejuense JS17-8T (98.1 %) and C. gleum ATCC 35910T (98.1 %). DNA-DNA hybridization values were 99-100 % among the five i… Read more

Monitoring of African swine fever in the wild boar population of the most recent endemic area of Spain

Investigation article published in Transboundary and Emerging Diseases

Wild boars are natural hosts for African swine fever (ASF). The ASF virus (ASFV) can persist for long periods in the environment, such as in ticks and contaminated products, which may be sources of infection for wild boar populations. African swine fever was eradicated in domestic pig populations in Spain in 1995, after 35 years of significant effort. To determine whether ASFV can persist in wild boar hosts after it has been eradicated from domestic pigs and to study the role of wild boar in helping ASFV persist in the environment, we checked for the presence of ASFV in wild boars in Doñ… Read more

Vacunas vectoriales frente a Gumboro como alternativa a los sistemas tradicionales de vacunación en pollitas de recría

Selecciones Avícolas publish this article

El agente etiológico de la bursitis infecciosa aviar -«infectious bursal disease» : IBD-, es un virus integrado en el género Avibirnavirus, y familia Birnaviridae. Fue aislado por primera vez en Gumboro, Delware -EE.UU.- y la enfermedad fue denominada inicialmente enfermedad de Gumboro. Mediante ensayos de neutralización cruzada, pueden diferenciarse los dos serotipos conocidos del virus de la bursitis infecciosa -IBDV-, los serotipos 1 y 2. El serotipo 1, es el único que se asocia con enfermedad clínica y contra el que han sido desarrolladas vacunas -OIE, 2008. Para ambos serotipos existe un … Read more
