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…

Intradermal Tuberculin Test in Water Buffalo (Bubalus bubalis): Experimental use of Mycobacterial Antigens for the Diagnosis of Bovine Tuberculosis
New article published in Journal of Buffalo Science
The study aims to evaluate the potential use of mycobacterial ESAT6 and CFP10 antigens, Early Secretory Proteins (ESP) in the Skin Test used for bovine tuberculosis (TB) diagnosis in Water Buffalo.
A pilot study was performed on 21 buffaloes from a TB outbreak and 11 buffaloes from a TB-free herd. Three concentrations of ESAT6-CFP10 (10, 20, and 30 µg) and two of ESP (50 and 100 µg) were inoculated in the Skin Test, along with PPDB, PPDA, and PBS as a negative control. Skin thickness was measured with calipers before the test and
every 24 hours for 4 days. Then, to evaluate the specificity…

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-e…

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…

Identification of putative volatile biomarkers of canine leishmaniasis in dog`s breath and hair employing a novel algorithm for automated chromatographic peak detection and matching
Investigation published in Analytical and Bioanalytical Chemistry
The analysis of the volatile compounds released by biological samples represents a promising approach for the non-invasive diagnosis of a disease. The present study, focused on a population of dogs infected with canine leishmaniasis, aimed to decipher the volatolomic profile associated with this disease in dogs, which represent the main animal reservoir for Leishmania pathogen transmission to humans. The volatiles emitted by the breath and hair of dogs were analysed employing the gas chromatography-mass spectrometry (GC-MS) technique. The acquired chromatograms were investigated using a novel …

Evaluación de una nueva estrategia para el diagnóstico humoral de la paratuberculosis caprina
New article published in Tierras. Caprino
La paratuberculosis (PTB) es una enfermedad con un gran impacto sanitario y económico en el ganado caprino y cuyo diagnóstico supone un gran desafÃo en la actualidad debido, entre otros factores, a la limitada capacidad de todas las técnicas ante-mortem disponibles para detectar la infección. Sin embargo, recientemente se ha evaluado una nueva estrategia diagnóstica que podrÃa mejorar el diagnóstico humoral de la enfermedad en caprinos empleando muestras de suero o leche…

ENZOEM y el grupo GISAZ de la Universidad de Córdoba, el Centro VISAVET de la Universidad Complutense de Madrid y la Unidad de InmunologÃa del Instituto de Salud Carlos III estudiaron el efecto protector y terapéutico del complejo proteico P22 frente a la tuberculosis caprina, hasta la fecha únicamente utilizado para diagnóstico. Tras la inmunización de animales sanos y pre-infectados con micobacterias del Complejo Mycobacterium Tuberculosis, se expusieron a animales enfermos y excretores. La inmunización confirmó el potencial de P22 para desencadenar una potente respuesta
