Persistent multispecies dissemination of armA-carrying IncR plasmids among clinical and environmental bacterial populations in a Spanish veterinary hospital

Artículo de investigación publicado en Journal of Clinical Microbiology

Aminoglycoside resistance mediated by 16S rRNA methyltransferases poses a growing threat in both human and veterinary medicine. Here, we conducted a retrospective genomic study of Enterobacterales isolates (n = 789) collected from clinical samples at a veterinary teaching hospital in Spain between 2011 and 2020. We identified four high-level aminoglycoside-resistant ST171 Enterobacter hormaechei subsp. xiangfangensis isolates carrying the armA gene, all from horses. Using Illumina and Nanopore sequencing, we determined that armA was located on a 70 kb IncR plasmid, also carrying other resistan… Leer más

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… Leer más

Evolution of Suspected Cat Abuse Between 2020 and 2024 in the Community of Madrid (Spain)

Artículo de investigación publicado en Animals

Animal abuse is a serious and underreported problem, with cats, particularly those living in colonies, being frequent victims. In Spain, reliable data on feline abuse are limited. This study evaluated the cause, manner and mechanisms of death from 53 cats over five years at the Pathology and Forensic Veterinary Unit of the VISAVET Health Surveillance Center in Madrid (Spain). More than half of the cats died from non-natural causes, including blunt force trauma, poisoning, and projectile injuries, while the remaining cats died from natural causes. Compared to a previous regional study, suspect… Leer más

Evidence of ESBL plasmid transfer and selective persistence of multiple host-associated Escherichia coli isolates in a chicken cecal fermentation model

Investigación publicada en Applied and Environmental Microbiology

The guts of animals and humans harbor diverse microbial communities that are regularly exposed to bacteria originating from food, water, and their surroundings. Species such as Escherichia coli are adept at colonizing multiple hosts, along with surviving in the environment. By encoding pathogenic traits and transmissible forms of antimicrobial resistance (AMR), E. coli can also pose a zoonotic risk. Our understanding of the factors that govern host residency is limited. Here, we used a chicken cecal fermentation model to study survival and the AMR transfer potential of 17 host-associated exten… Leer más

Evaluación de cepas del virus de la peste porcina Africana de baja a moderada virulencia: perspectivas de expertos e implicaciones para los planes de vigilancia

El premio será entregado en la próxima Reunión Anual de la @americancollegevetpath ACVP en Nueva Orleans, Luisiana, EE. UU.… Leer más

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… Leer más

Wild boar trade and African swine fever risk of introduction into new territories: A quantitative release assessment with retrospective data of wild boar shipments to France and Spain (2010–2017)

Investigación publicada en One Health

Wild boar (WB) (Sus scrofa) farming and trade in EU countries consistently developed at the end of the last century, primarily for repopulating hunting estates within the sport hunting industry. Since the introduction of African swine fever (ASF) in the Caucasus in 2007 and its subsequent spread from Eastern to Central Europe, international WB trade increased the risk of ASF introduction into new territories. In order to prevent such events, the EU veterinary authorities decided to ban WB trade in June 2018. In our study, we documented retrospective WB trade movements to France and Spain betwe… Leer más

Epidemiología de la resistencia a aminoglucósidos y macrólidos en Campylobacter termotolerantes en animales de abasto en España

Tesis Doctoral defendida por Vicente López Chavarrías en el Centro VISAVET de la Universidad Computense de Madrid

La resistencia a los antimicrobianos es un problema importante para el tratamiento de enfermedades causadas por bacterias zoonóticas como Campylobacter termotolerantes (C. coli y C. jejuni). Los mecanismos mediante los cuales la resistencia a los antimicrobianos se propaga en las poblaciones bacterianas, especialmente a través de transferencia horizontal de genes, pueden tener graves consecuencias dependiendo de la velocidad con que los fenotipos resistentes se diseminan entre animales de producción, los seres humanos y el medio ambiente. Son particularmente relevantes los determinantes gen… Leer más
