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 publica este artículo de investigación

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… Leer más

Landscape connectivity for predicting the spread of ASF in the European wild boar population

Artículo de investigación publicado en 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… Leer más

Forensic investigations of suspected livestock depredation by vultures: scientific tools for compensation programmes

Journal of Comparative Pathology publica este artículo de investigación

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… Leer más

Effect of a recent intradermal test on the specificity of P22 ELISA for the diagnosis of caprine tuberculosis

Investigación publicada en 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… Leer más

Non-tuberculous mycobacteria: occurrence in skin test cattle reactors from official tuberculosis-free herds

Artículo de investigación publicado en 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… Leer más

Aspectos inmunológicos de la tuberculosis pulmonar ovina: estudio histológico e inmunohistoquímico

Trabajo Fin de Grado defendido por Enni Amanda Ramirez Vuori

Las especies del complejo Mycobacterium tuberculosis (CMT) son capaces de infectar a un amplio rango de hospedadores entre los que destacan las ovejas que pueden actuar como reservorios. Nuestro objetivo fue caracterizar histológica e inmunohistoquímicamente los granulomas pulmonares causados por tres especies del CMT (M. bovis, M. caprae y M. tuberculosis) en oveja (Ovis orientalis aries). Mediante un estudio retrospectivo se incluyeron 12 animales inoculados experimentalmente vía hematógena. Se clasificaron, cuantificaron y describieron los granulomas empleando las tinciones de hematoxilina-… Leer más

Detection of Brucella in Dermacentor ticks of wild boar with brucellosis

Transboundary and Emerging Diseases publica este artículo de investigación

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… Leer más

Identification of promoter activity in gene-less cassettes from Vibrionaceae superintegrons

Artículo de investigación publicado en Nucleic Acids Research

Integrons are genetic platforms that acquire new genes encoded in integron cassettes (ICs), building arrays of adaptive functions. ICs generally encode promoterless genes, whose expression relies on the platform-associated Pc promoter, with the cassette array functioning as an operon-like structure regulated by the distance to the Pc. This is relevant in large sedentary chromosomal integrons (SCIs) carrying hundreds of ICs, like those in Vibrio species. We selected 29 gene-less cassettes in four Vibrio SCIs, and explored whether their function could be related to the transcription regulation o… Leer más

Heat-inactivated mycobacteria activate the toll-like receptor 2 and 4 pathways in the zebrafish model of tuberculosis

Investigación publicada en Vaccine

Based on previous evidence demonstrating the efficacy of inactivated mycobacteria for the control of fish mycobacteriosis, we explored the protective efficacy of two inactivated Mycobacterium bovis administered via parenteral and mucosal routes against Mycobacterium marinum infection mimicking natural conditions in the zebrafish model of tuberculosis. Although we did not observe a clear effect of any of the immunostimulants on mycobacterial burden, the results showed a significant increase in TLR2 and TLR4 gene expression levels in fishes parenterally immunized with inactivated Bacillus Calmet… Leer más

Intrapancreatic accessory spleens in African swine fever infection of wild boar (Sus scrofa)

Artículo de investigación publicado en Frontiers in veterinary science

Intrapancreatic accessory spleen (IPAS) is one of the most frequent congenital splenic anomalies in humans; however, studies in veterinary medicine are scarce. This study aimed to describe the macroscopic, histopathological and immunohistochemical features of 11 suspected cases of IPAS in wild boar piglets of 3–4 months old. Seven of the 11 animals were immunised with a low virulence isolate of African swine fever virus (ASFV) and subsequently challenged with a highly virulent ASFV isolate (LVI-HVI group). The remaining four animals were exclusively infected with a highly virulent isolat… Leer más
