Abattoir Surveillance: Identifying Risk Factors Associated with Bovine Tuberculosis Lesion Detection in a Low Prevalence Region
Preventive Veterinary Medicine publica este artículo de investigación
Abattoir surveillance is a key component in control and eradication programs against bovine tuberculosis (bTB). In low-prevalence or officially tuberculosis-free (OTF) regions in which active surveillance is typically limited or non-existent, postmortem inspection at the abattoir constitutes one of the main diagnostic tool to guarantee the absence of disease transmission. Here, we evaluated the performance of abattoir postmortem inspection in Galicia, a low-prevalence region in Spain (now OTF). Between 2014 and 2019, 1,784,261 animals were culled in 41 abattoirs, of which a small proportion (0…

Long-Term Surveillance of Chlamydia psittaci and West Nile Virus in Wild Birds from Central Spain (2013–2022)
Investigación publicada en Microorganisms
Wild birds are relevant reservoirs and sentinels for zoonotic pathogens such as Chlamydia psittaci and West Nile virus (WNV), both of which can affect animal and public health. Wildlife rehabilitation centers (WRCs) offer unique opportunities for passive surveillance
of emerging and re-emerging infectious diseases, particularly in urban and peri-urban settings. From 2013 to 2022, a total of 1024 bird samples were collected upon admission to WRCs in the Community of Madrid, Spain. Oropharyngeal and cloacal swabs, as well as
tissue samples, were tested using real-time PCR targeting the ompA ge…

Severe Generalized Tetanus in a Chimpanzee (Pan troglodytes) Under Human Care: A Case Report from the Republic of Congo
Veterinary sciences publica este artículo de investigación
Tetanus is a life-threatening disease that causes painful muscle stiffness and sudden spasms. We present the case of a young chimpanzee (Pan troglodytes) that was rescued from the illegal wildlife trade and arrived at a sanctuary with deep, dirty wounds and signs of tetanus. This included difficulty opening his mouth, a rigid posture, and spasms triggered by noise or touch, all while he remained fully conscious. The veterinary team acted immediately, cleaning and removing dead tissue from the wounds, administering an antitoxin to neutralize the toxin, starting a vaccination programme to protec…

Characterization of Leishmania infantum Isolates from Wild Leporids in the Community of Madrid (Spain)
Investigación publicada en Veterinary sciences
Despite the public health implications of limited awareness regarding the biodiversity of Leishmania spp. and the persistence of human leishmaniasis outbreaks in endemic regions of Europe, there is still no consensus on a standardized molecular typing method for the surveillance of this parasite in humans, domestic animals, and wildlife reservoirs. Consequently, the development of a simple, rapid, effective, and cost-efficient typing approach remains an unmet need. The method proposed in this study, evaluated on a larger number of samples than in previous reports, may fulfill these criteria an…

Evaluation of the reproducibility and performance characteristics of the Phagomagnetic separation-qPCR assay for rapidly detecting viable Mycobacterium avium subsp. paratuberculosis in bovine milk and feces
Artículo de investigación publicado en Frontiers in veterinary science
Inter-laboratory trials were carried out to evaluate the reproducibility and estimate test performance characteristics of the Phagomagnetic separation (PhMS)-qPCR assay, a novel phage-based assay recently developed as a rapid alternative to culture for detecting viable Mycobacterium avium subsp. paratuberculosis (MAP) in bovine milk and feces. Unique reagents and a detailed instruction manual required for the PhMS-qPCR assay were provided to five European veterinary diagnostic laboratories by Rapid-Myco Technologies Limited. Milk and feces test panels were prepared at NEIKER and distributed to…

Viral Distribution of Wild Boar Exposed to Low (Vaccine Candidate) and High Virulence African Swine Fever Virus Isolates: Immunohistochemical Characterization
Investigación publicada en Transboundary and Emerging Diseases
Although several biosecurity and control measures are currently in place to mitigate the African swine fever (ASF) epidemic, vaccination is being explored as a potential long-term strategy. However, standardized guidelines for evaluating the safety and efficacy of ASF vaccines are not yet fully established. Understanding infection dynamics in wild boar is crucial, as they play a key role in the spread and persistence of the virus. This work aims to provide comprehensive information on viral distribution through immunohistochemical analysis (p72) with histopathologic assessment in wild boar. Th…

Retrospective analysis of the clinical approach practiced in dog bite cases caused by Vipera latastei, Vipera seoanei and Vipera aspis
Artículo de investigación publicado en The Veterinary Journal
Snakebites pose a significant public health risk to both humans and animals in many countries. In Spain, the presence of three viper species, Vipera latastei, Vipera seoanei, and Vipera aspis, complicates clinical management in veterinary settings. There is currently no standardized veterinary protocol for treating viper bites in many countries. This retrospective study analyzed the clinical approaches employed by Spanish veterinary centers in treating canine viper bites within the distribution range of these species. Data from 62 clinical cases across 58 veterinary centers were reviewed, incl…

Risk Mapping of African Swine Fever in Domestic Pigs and Wild Boars to Enhance Management and Surveillance in Asia
Transboundary and Emerging Diseases publica este artículo de investigación
African swine fever (ASF) is a highly lethal disease affecting domestic pigs and wild boars, caused by the ASF virus (ASFV), which has rapidly spread across Asia in recent years. In this region, most reported ASF cases involve domestic pigs, while cases in wild boars remain notably lower except in a few countries. However, factors such as the high population of wild boars, limited wildlife surveillance, and inadequate farm biosecurity suggest that the prevalence and transmission of ASFV between these hosts may be underestimated. Therefore, we used a simplified multicriteria approach (SMCA) to …

Complement system activation in wild boar (Sus scrofa) following parenteral administration of heat-inactivated Mycobacterium bovis
Artículo de investigación publicado en Frontiers in veterinary science
Introduction: Development of vaccines to preserve and improve human and animal health requires effective protective antigens, delivery platforms, and adjuvants. The immunostimulant based on heat-inactivated Mycobacterium bovis (IV) was developed to boost protective immune response in different animal species against pathogen infection and tick infestations.
Methods: In this study, a serum proteomics approach was used with functional annotations and enrichment network analysis for the characterization of immune pathways and biomarkers associated with parenteral administration of one, two, or t…

Antibiotic Resistance to Critically Important Antimicrobials and Virulence Genes in Enterococcus faecalis Strains Isolated from Eurasian Griffon Vultures (Gyps fulvus) and Their Association with Mobile Genetic Elements
Artículo de investigación publicado en Veterinary sciences
The phenotypic resistance of 56 Enterococcus faecalis isolates from Eurasian griffon vultures was subjected to surveillance testing with the microdilution method using a standardized panel of antimicrobials. Isolates were also characterized by MLST. Additionally, the genome of 19 isolates with phenotypic resistance to linezolid, ciprofloxacin, chloramphenicol and/or high-level resistance to gentamicin were sequenced to determine their antimicrobial resistance (ARGs) and virulence-associated genes and to identify mobile genetic elements (MGEs). Most isolates (82.1%) exhibited non-wild-type phen…
