Application of a specific quantitative real-time PCR (qPCR) to identify Leishmania infantum DNA in spleen, skin and hair samples of wild Leporidae

Veterinary Parasitology publica este artículo de investigación

The aim of this study was to compare a quantitative real-time PCR (qPCR) validated for the detection of Leishmania infantum in dogs with a nested PCR but in wild Leporidae. Additionally, L. infantum results from indirect immunofluorescent antibody test (IFAT) and in vitro culture were also compared with qPCR. Different samples (spleen, skin and hair) recovered from 224 European rabbits and 70 Iberian hares from two green areas of Madrid Council were analysed for the detection of L. infantum. The presence of Leishmania kDNA was detected by qPCR in 58 out of 221 (26.24%), 162 out of 203 (79.8%) … Leer más

Oral Vaccination with Heat-Inactivated Mycobacterium bovis Does Not Interfere with the Antemortem Diagnostic Techniques for Tuberculosis in Goats

Frontiers in veterinary science publica este artículo de investigación

Vaccination against tuberculosis (TB) is prohibited in cattle or other species subjected to specific TB eradication campaigns, due to the interference that it may cause with the official diagnostic tests. However, immunization with a heat-inactivated (HI) Mycobacterium bovis vaccine via the oral route has been suggested to overcome this issue. In this study, the main goal was to assess the interference of the HI vaccine by different routes of administration using a previous vaccination and re-vaccination (boosting) protocol. TB-free kid goats were divided into three groups: oral (n = 16), intr… Leer más

Presencia de los genes de resistencia a colistina mcr-1 y mcr-3 en una cepa multirresistente de ganado bovino

Investigación publicada en Eurosurveillance

Los genes de resistencia a colistina, mcr-3 y mcr-1, han sido detectados en una cepa de Escherichia coli procedente de heces de bovino recogidas en un matadero español en 2015. Las secuencias de ambos genes hibridaron con la misma banda plasmídica de aproximadamente 250 kb, aunque la resistencia a colistina no fue movilizable. El aislado era un E. coli productor de beta-lactamasas de amplio espectro, identificado como serotipo O9: H10, ST533. Se trata de la primera descripción del gen mcr-3 en Europa, después de los trabajos publicados con muestras de Asia y Estados Unidos.… Leer más

AIE: Anemia Infecciosa Equina

Publicado un nuevo artículo online de divulgación en VISAVET Outreach Journal

La anemia infecciosa equina (AIE) o fiebre de los pantanos es una enfermedad infecciosa crónica exclusiva de los équidos, producida por un lentivirus de la familia Retroviridae. En este artículo se resumen los aspectos más importantes de la transmission, signos clínicos, diagnóstico y medidas de control a implementar cuando se confirma el diagnóstico, así como la situación actual de la enfermedad en España.… Leer más

Technological advances in veterinary diagnostics: opportunities to deploy rapid decentralised tests to detect pathogens affecting livestock

Revue Scientifique et Technique publica este artículo de investigación

Sustainable food production capable of feeding a growing human population is a significant global challenge, and is a priority encompassed within the United Nations Millennium Development Goal to `eradicate extreme poverty and hunger`. Infectious diseases reduce the productivity of farm animals, and the globalised trade of animals and their products increases the threat of disease incursion. Accurate and rapid diagnostic tests are an essential component of contingency plans to detect, control and eradicate such diseases. Diagnosis involves a `pipeline` that normally starts with clinical suspic… Leer más

Isolation of Brachyspira species from farmed wild boar in Spain

Artículo de investigación publicado en The Veterinary Record

Bacteria belonging to the genus Brachyspira are gram-negative, anaerobic, spirochaetes adapted to occupy specialised niches in the large intestines of animals, including swine.1 Brachyspira species cause important digestive diseases such as swine dysentery (Brachyspira hyodysenteriae) and porcine intestinal spirochetosis (Brachyspira pilosicoli), which have a significant economic impact on the swine industry. Spain has major problems associated with swine dysentery, as demonstrated by Carvajal and others, who showed that more than 30% of Spanish farms and 12% of porcine faecal specimens tested… Leer más

Effect of seafood peptones on biomass and metabolic activity by Enterococcus faecalis DM19

Investigación publicada en LWT - Food Science and Technology

Eight seafood protein hydrolysates (SPHs) obtained from squid, shrimp and fish gelatin were incorporated as substitutes of peptones in culture media in order to evaluate its effect on survival and metabolic activity (lactic acid, acetic acid and bacteriocins production) of Enterococcus faecalis DM19. The substitution of commercial peptones in culture media by either a shrimp hydrolysate prepared with Protamex, or by squid protein hydrolysates prepared with Esperase or Alkaline protease, stimulated E. faecalis DM19 growth up to 16%. The incorporation of SPHs, mainly from shrimp, in the culture … Leer más

Serological Surveillance and Direct Field Searching Reaffirm the Absence of Ornithodoros Erraticus Ticks Role in African Swine Fever Cycle in Sardinia

Investigación publicada en Transboundary and Emerging Diseases

African swine fever (ASF), one of the most important diseases of swine, has been endemic in the Italian island of Sardinia for more than 35 years. During these decades, several strategies and eradication efforts have been implemented in the island with limited success. Strong climatic and ecological similarities exist between Sardinia and one area of the Iberian Peninsula where Ornithodoros erraticus ticks were involved in the persistence of ASF from 1960 to 1995. This fact leads to the hypothesis that, potentially, Ornithodoros ticks could be also involved in the ASF cycle in Sardinia, thus a… Leer más
