Healthcare-related transmission of mobile genetic elements co-carrying blaNDM and 16S rRNA methyltransferase genes in multiple Enterobacterales

Microbial Genomics publica este artículo de investigación


Aminoglycosides are used in the treatment of serious infections with Gram-negative bacteria, especially those resistant to beta-lactams and carbapenems. 16S rRNA methyltransferases (16S-RMTase) are capable of conferring resistance to nearly all aminoglycosides. They are sometimes detected in combination with bla NDM. This study describes the mobile genetic elements associated with bla NDM and 16S-RMTase (co-)carriage in Enterobacterales from Ireland in the period 2019-2023. All isolates (n=58) carrying both bla NDM and a 16S-RMTase gene between 2019 and 2023 were obtained from the CPE National… Leer más

Tracking trouble: sources, persistence, and risk factors of antimicrobial-resistant Escherichia spp in freshwater fish farms of north-west France

Comunicación oral en Seminarios VISAVET 2025


Antimicrobial resistance (AMR) poses a growing threat to human and animal health, and its spread in the environment is increasingly being reported. As it depends on surface water, fish farming is particularly exposed to fecal pollution from wastewater effluents and agricultural runoff, despite regulations. Resistant bacteria can enter fish farms through multiple routes, including polluted water, where they can persist and interact with aquatic bacteria. This study aimed at identifying sources of antimicrobial-resistant Escherichia coli in freshwater fish farms located in France, and at assessi… Leer más

Primary leptomeningeal histiocytic lymphoproliferative disorder associated with SARS-CoV-2 brain infection in k18-hACE2 mouse: a case report

Laboratory Animal Research publica este artículo de investigación


Background: Histiocytic proliferative disorders in the central nervous system are rare, and their potential association with viral infections remains largely unexplored. This case is relevant because it suggests a potential interaction between SARS-CoV-2 neuroinvasion and tumor development, providing insights into how viral infections might influence oncogenesis. Case presentation: A 4.5-month-old male k18-hACE-2 mouse, part of an experimental study of SARS-CoV-2, displayed a small mass in leptomeningeal area composed by neoplastic round cells. This process is associated with typical acute in… 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

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
