La tuberculosis, una enfermedad zoonótica de preocupación mundial

Repasamos dos artículos publicados este mes que nos acercan investigaciones recientes en el campo de esta enfermedad

La tuberculosis animal, causada por el complejo Mycobacterium tuberculosis, es una enfermedad zoonótica de preocupación mundial y tiene una amplia variedad de reservorios domésticos y silvestres que pueden establecer sistemas epidemiológicos complejos. El principal agente etiológico de la tuberculosis en el ganado es
Mycobacterium bovis y los casos de tuberculosis humana causados ​​por M. bovis son raros. Sin embargo esta especie también infecta a los seres humanos por inhalación o ingestión y causa una tuberculosis clínicamente indistinguible de la causada por M. tuberculosis. Leer más

The plasmid-mediated Kluyvera-like arnBCADTEF operon confers colistin (hetero) resistance to Escherichia coli

Antimicrobial Agents and Chemotherapy publica este artículo de investigación


The use of colistin as a last resort antimicrobial is compromised by the emergence of resistant enterobacteria with acquired determinants like mcr genes, mutations that activate the PmrAB system and by still unknown mechanisms. This work analyzed 74 E. coli isolates from healthy swine, turkey or bovine, characterizing their colistin resistance determinants. The mcr-1 gene, detected in 69 isolates, was the main determinant found among which 45% were carried by highly mobile plasmids, followed by four strains lacking previously known resistance determinants or two with mcr-4 (one in addition to … Leer más

Population genomics and antimicrobial resistance dynamics of Escherichia coli in wastewater and river environments

Investigación publicada en Communications Biology


Aquatic environments are key niches for the emergence, evolution and dissemination of antimicrobial resistance. However, the population diversity and the genetic elements that drive the dynamics of resistant bacteria in different aquatic environments are still largely unknown. The aim of this study was to understand the population genomics and evolutionary events of Escherichia coli resistant to clinically important antibiotics including aminoglycosides, in anthropogenic and natural water ecosystems. Here we show that less different E. coli sequence types (STs) are identified in wastewater tha… Leer más

Description and implementation of an On-farm Wildlife Risk Mitigation Protocol at the wildlife-livestock interface: tuberculosis in Mediterranean environments

Preventive Veterinary Medicine publica este artículo de investigación


Animal tuberculosis (TB), which is caused by the Mycobacterium tuberculosis complex (MTC), is a zoonotic disease of global concern, and has a wide variety of wild and domestic reservoirs that can establish complex epidemiological systems. Of all the strategies employed to control TB, reducing the risks of interaction at the wildlife-livestock interface is a cornerstone. However, detailed protocols with which to assess and implement farm-specific preventive actions that can be employed against interactions with wildlife are lacking for extensive production systems. We describe an On-farm Wildli… Leer más

Effect of Biscuit Flour and Fermented Defatted Alperujo Co-Administration on Intestinal Mucosa Morphology and Productive Performance in Laying Hens

Artículo de investigación publicado en Animals


In this study, the effects of co‐administration with biscuit flour and fermented defatted “alperujo” (FDA) on gut health were evaluated in a batch of laying hens (Hy‐Line 2015) on a commercial farm. Animals were divided into two groups: control group and treatment group; and histological and morphometric analyses of all sections of the intestine (duodenum, jejunum, ileum, cecum and rectum) were performed at 10, 18, 25, 50 and 75 weeks of age. During the whole productive period, a decrease in the mortality rate (p = 0.01) was observed in treated hens, as well as an increase in the n… Leer más

Spoligotype-specific risk of finding lesions in tissues from cattle infected by Mycobacterium bovis

BMC Veterinary Research publica este artículo de investigación


Although the pathogenic effect of members of the Mycobacterium tuberculosis complex in susceptible hosts is well known, differences in clinical signs and pathological findings observed in infected animals have been reported, likely due to a combination of host and pathogen-related factors. Here, we investigated whether Mycobacterium bovis strains belonging to different spoligotypes were associated with a higher risk of occurrence of visible/more severe lesions in target organs (lungs and/or lymph nodes) from infected animals. A large collection of 8889 samples belonging to cattle were classifi… Leer más

Polyresistant Mycobacterium bovis Infection in Human and Sympatric Sheep, Spain, 2017-2018

Artículo de investigación publicado en Emerging Infectious Diseases


The main etiologic agent of tuberculosis (TB) in livestock is Mycobacterium bovis; human TB cases caused by M. bovis are rare. Analysis of a TB outbreak caused by polyresistant M. bovis involving a human and sympatric sheep in Spain suggests local circulation of drug-resistant M. bovis strains among livestock… Leer más

Evaluation of the performance of slaughterhouse surveillance for bovine tuberculosis detection in Castilla y Leon, Spain

Artículo de investigación publicado en Preventive Veterinary Medicine


Post-mortem inspection (PMI) of routinely slaughtered cattle in abattoirs is an extremely valuable tool for detecting bovine tuberculosis (bTB) infected herds that can supplement active surveillance activities. However, its true performance is difficult to assess due to the multiple factors that may affect it. Here, we determined relative efficiencies in the detection of bTB-compatible lesions and probabilities of subsequent laboratory confirmation of abattoirs located in Castilla y Leon, one of the regions with the largest cattle population in Spain, between 2010 and 2017. The slaughtered ani… Leer más

Antibiotic use in the COVID-19 crisis in Spain

Investigación publicada en Clinical Microbiology and Infection


Before the coronavirus disease 2019 (COVID-19) pandemic, antimicrobial resistance was the world`s most pressing health crisis. The United Nations, the World Health Organization (WHO) and the European Center for Disease Control and Prevention have made antimicrobial resistance a top priority, establishing a task force in the G-20 and organizing a joint program initiative on antimicrobial resistance including countries from al over the world [1]. However, with the emergence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus pandemic in January 2020, all efforts are now foc… Leer más

Towards a Better and Harmonized Education in Antimicrobial Stewardship in European Veterinary Curricula

Investigación publicada en Antibiotics


Education in antimicrobial stewardship (AMS) in veterinary medicine is essential to foster responsible antimicrobial use and control of antimicrobial resistance (AMR) in animals. AMS is listed by the EU and international organizations among the basic `Day One Competences` required of veterinary students upon graduation. Our aim was to evaluate the quality of education of European veterinary students in AMS. We distributed a 27-item survey addressing the perceptions of preparedness and acquired skills on key topics related to AMS to final-year veterinary students in Europe. We collected 3423 co… Leer más
