Application of machine learning with large-scale data for an effective vaccination against classical swine fever for wild boar in Japan
Investigation article published in Scientific reports
Classical swine fever has been spreading across the country since its re-emergence in Japan in 2018. Gifu Prefecture has been working diligently to control the disease through the oral vaccine dissemination targeting wild boars. Although vaccines were sprayed at 14,000 locations between 2019 and 2020, vaccine ingestion by wild boars was only confirmed at 30% of the locations. Here, we predicted the vaccine ingestion rate at each point by Random Forest modeling based on vaccine dissemination data and created prediction surfaces for the probability of vaccine ingestion by wild boar using spatial…

Evaluation of the Effect of a Recent Comparative Intradermal Tuberculin Test on the Humoral Diagnosis of Paratuberculosis Using Serum and Milk Samples from Goats
Veterinary sciences publish this investigation article
Paratuberculosis (PTB) and tuberculosis (TB) are two mycobacterial diseases with a severe economic and health impact on domestic ruminants. The ante mortem diagnosis of PTB is hampered, among other factors, by the limited sensitivity of all the available diagnostic techniques. Since TB-infected goats subjected to the comparative intradermal tuberculin test (CITT) may experience a booster effect on their antibody titer and a potential enhancement to the sensitivity of humoral techniques for tuberculosis, in the present study we aimed to evaluate this diagnostic strategy on the humoral diagnosis…

Editorial: Epidemiology of the transboundary swine diseases in Asia & Pacific
Investigation published in Frontiers in veterinary science
Asia is a leading market for pork production and consumption, contributing to over half of the world’s pork supply. Smallholder-based swine management systems, which are sensitive to infectious diseases, are still prevalent in many Asian countries and directly
linked to the vulnerability of the pig value chain at the national level. This is a major characteristic of the swine production in many Asian countries. For these traditional pig farming systems, the industry is now facing a critical turning point. In recent years, several transboundary swine diseases such as African Swine Fever (ASF),…

Phenotypic and genetic characterization of antimicrobial resistance in Salmonella enterica serovar Choleraesuis isolates from humans and animals in Spain from 2006 to 2021
Investigation published in The Journal of Antimicrobial Chemotherapy
Objectives
While an increase in the levels of MDR in Salmonella enterica sevorar Choleraesuis has been reported in Europe, little is known about the situation in Spain. Therefore, we first aimed to assess the phenotypic resistance profile and to determine the presence of genetic determinants of resistance of S. Choleraesuis isolates collected in animal and human. Our second objective was to identify and characterize clusters of highly related isolates.
Methods
We analysed 50 human and 45 animal isolates retrieved from 2006 to 2021 using the disc diffusion method and performed WGS followed…

Landscape connectivity for predicting the spread of ASF in the European wild boar population
Investigation article published in Scientific reports
African swine fever (ASF) is an infectious and highly fatal disease affecting wild and domestic swine, which is unstoppably spreading worldwide. In Europe, wild boars are one of the main drivers of spread, transmission, and maintenance of the disease. Landscape connectivity studies are the main discipline to analyze wild-species dispersal networks, and it can be an essential tool to predict dispersal-wild boar movement routes and probabilities and therefore the associated potential ASF spread through the suitable habitat. We aimed to integrate wild boar habitat connectivity predictions with th…

Forensic investigations of suspected livestock depredation by vultures: scientific tools for compensation programmes
Journal of Comparative Pathology publish this investigation article
Human–wildlife conflicts may have devastating consequences for fauna due to targeting by humans of wildlife populations suspected to have predated livestock. Suspicion of depredation of extensively raised livestock by vultures in Europe has triggered public administration-led forensic investigations intended to distinguish between predation and scavenging in order to compensate farmers for attacks on their livestock. In this study, gross and histological analyses were carried out on suspected cases of domestic animal depredation by griffon vultures (Gyps fulvus) over a 1-year period. Fifty-eig…

Effect of a recent intradermal test on the specificity of P22 ELISA for the diagnosis of caprine tuberculosis
Investigation published in Frontiers in veterinary science
Caprine tuberculosis (TB) is a zoonotic disease caused by members of the Mycobacterium tuberculosis complex. TB eradication programs in goats are based on the single and comparative intradermal tuberculin tests (SITT and CITT, respectively). Antibody-based diagnostic techniques have emerged as potential diagnostic tools for TB. P22 ELISA has been previously evaluated using samples collected after the intradermal tuberculin tests to maximize the sensitivity, a phenomenon known as booster effect. However, there is no information available on whether the use of this diagnostic strategy could lead…

Non-tuberculous mycobacteria: occurrence in skin test cattle reactors from official tuberculosis-free herds
Investigation article published in Frontiers in veterinary science
Non-tuberculous mycobacteria (NTM) are considered a relevant cause of non-specific reactions to the most widely applied bovine tuberculosis (bTB) test, the intradermal tuberculin test. In order to establish which NTM species might act as a potential source of such diagnostic interference, a collection of 373 isolates obtained from skin test positive cows from 359 officially tuberculosis-free (OTF) herds, culled in the framework of the bTB eradication campaign in Spain, were identified at the species level through PCR and Sanger sequencing of the 16S rDNA, hsp65 and rpoB genes. Of the 308 isola…

Immunological aspects of ovine pulmonary tuberculosis: histological and immunohistochemical study
Degree Final Project defended by Enni Amanda Ramirez Vuori
Mycobacterium tuberculosis complex (MBC) species are capable of infecting a wide range of hosts, including sheep, which can act as reservoirs. Our objective was to characterize histologically and immunohistochemically the pulmonary granulomas caused by three species of MTC (M. bovis, M. caprae and M. tuberculosis) in sheep (Ovis orientalis aries). Twelve animals experimentally inoculated via hematogenous route were included in a retrospective study. Granulomas were classified, quantified and described using hematoxylin-eosin and Masson`s trichrome stains. Histological study of the lesions reve…

Detection of Brucella in Dermacentor ticks of wild boar with brucellosis
Transboundary and Emerging Diseases publish this investigation article
Brucellosis is a sanitary and economically relevant disease affecting humans, livestock, and wildlife. Ticks have been suggested as vectors, long-term carriers, and amplifiers of Brucella. In this study, ticks from wildlife ungulate hosts living in hunting reserves of a central region of Spain were collected during a 6-year period, pooled, and screened for Brucella spp. by PCR. Aiming to correlate Brucella spp. DNA presence in ticks with Brucella spp. infections in wildlife ungulate hosts, liver samples from deceased wildlife ungulates coming from the hunting reserves showing a positive result…
