Project:
CIAOCIAO! Comparative Impact Assessment of Options to Curtail Inessential Antimicrobials On-farm
01.05.2018 to 30.04.2022
General project description 

Since the 1950s, antimicrobials have been increasingly used in modern intensive livestock production systems. Besides preventive and therapeutic use, antimicrobials were used as growth promoters in the European Union (EU) until their ban in 2006. This was preceded by decades of growing evidence and concerns about the public health impact of widespread veterinary antimicrobial use (AMU) and associated increasing antimicrobial resistance (AMR). As AMU in livestock favors AMR development in bacterial populations as it does in humans, the public health risks of veterinary AMU are threefold: 1) resistant bacteria can pass onto humans via direct contact with animals; 2) these bacteria can pass on via food of either animal origin or cross-contaminated during production; 3) these bacteria can spread into the environment via farm runoff or unprocessed manure used as fertilizer. Moreover, large volumes of antimicrobial residues in manure cause further environmental exposure and potential selective pressure. In 2007, the Netherlands was the largest veterinary antimicrobial consumer per biomass unit of animal production among 10 EU countries. Together with the discovery of large reservoirs of methicillin-resistant S. aureus (MRSA) and Extended-Spectrum Beta-Lactamase (ESBL)-producing bacteria in Dutch livestock, this led to considerable socio-political pressure, with the government imposing 20%, 50% and 70% AMU reductions in livestock in 2011, 2013 and 2015, respectively. After an initial rapid AMU reduction (56% in 2013), mostly attributable to replacing group treatments, adopting herd health and treatment plans, guidelines, benchmarking systems and transparency in prescriptions, a 58% AMU reduction was reported in 2015, indicating that a 70% of higher AMU reduction would require more fundamental changes in the livestock production systems rather than in prescribing procedures alone. Indeed some structural differences in AMU still exist between Dutch livestock farms and overall AMU remains high in a subset of them, mainly because of the highly intensive nature of the Dutch farming industry. Moreover, in recent years AMU reduction has levelled off despite further reduction is sought after, particularly in broilers, weaned piglets and veal calves, whose groups now account for most AMU in Dutch livestock. An important counter argument is the increased economic burden placed on the farmers and eventually on the consumers through further restriction to veterinary AMU when this is needed for therapeutic purposes. A rise in livestock production costs would be unbearable in the highly competitive international agricultural market wherein the Dutch livestock industry relies heavily on exports. Providing the right conditions for incentivizing further AMU reduction in Dutch livestock requires an assessment of the potential impact on AMU and associated (negative or positive) financial effects of the available interventions aiming at keeping livestock healthy, on the principle that every infection prevented is an opportunity for no treatment. Policy makers and livestock producers would then be able to consider supporting the implementation of a specific intervention instead of another based their cost-effectiveness. These interventions include: (i) infection control (i.e. enhanced farm biosecurity and hygiene standards), (ii) animal husbandry practices (i.e. enhanced farm management, e.g. low-stock density farming, all-in/all-out production systems, rearing of slow-growing breeds, etc.), (iii) vaccination (for bacterial diseases, but also viral diseases often complicated by secondary bacterial infections). Indeed, there is still no quantitative evidence for the impact of these interventions on AMU, and even less evidence for their sustainability. Consequently, comprehensive recommendations to farmers about which interventions are most cost-effective and would best suit their specific situations in relation to the public health needs remain rather vague (e.g. as general statements like ‘increased vaccination’ or ‘improved biosecurity’) or are based on individual veterinarians’ personal experience and opinion. As a collaboration of two leading institutions in animal and public health in the Netherlands (Veterinary Medicine Faculty of Utrecht University and the RIVM) and using both existing and newly collected data, we will quantify in a scenario-based modelling framework the impact of different biosecurity/hygiene standards, vaccination schemes and husbandry practices on AMU reduction (overall and for specific antimicrobials) in broilers, weaned piglets and veal calves, including their cost-effectiveness. Determining the impact and feasibility of these interventions will provide livestock producers and policy makers with a management tool to set targets and draw plans for the implementation of those interventions with the highest potential for AMU reduction, and so decreasing AMR in a rational and sustainable way.

Project:
Discerning Environmental Pathways of Campylobacter Transmission (DEPiCT)
01.03.2017 to 27.02.2021
General project description 

Campylobacteriosis is the primary zoonosis in Europe, causing over 1.6 M cases and €76 M costs annually in the Netherlands alone (~17 M people). Most cases are caused by Campylobacter jejuni and C. coli, which are widespread in livestock and wildlife, providing many ways for human exposure beyond just food. Despite all the research and control efforts in the food chain, there is no significant decrease in human campylobacteriosis. Up to 80% of human campylobacteriosis cases can be attributed to the poultry reservoir, but only ~40% of poultry-borne cases are attributable to poultry consumption; thus, many poultry-borne Campylobacter strains infect humans via other routes. Campylobacter is often found in environmental sources like surface water, indicating recent contamination with (animal) fecal material, but its environmental routes are still largely unexplored. While Campylobacter survives poorly outside the host, there are some environmentally adapted strains that play a key role in the transmission between animals and humans via the environment. Surface water is a ‘sink’ that collects Campylobacter strains from different hosts whose relative contributions are largely unknown, though wild birds are thought to play a major role. However, the devastating H7N7 bird flu epidemic hitting the Netherlands in 2003 showed that even without a huge drop in poultry consumption, the massive poultry culling and closure of poultry abattoirs to contain the epidemic was associated with a 44-50% drop in human campylobacteriosis where these measures were enforced, suggesting a major role of the environment in human exposure to poultry-borne strains. Moreover, while studies show that poultry and wild birds are the most important contributors to Campylobacter surface water pollution, their contributions vary with the size of the poultry production. The environment may also act as a source of Campylobacter (re)colonization in livestock. As the environment seems to be a key player in Campylobacter epidemiology and the non-foodborne side of campylobacteriosis receives little attention despite its potential to provide new targets for Campylobacter control and research, this project will discern the origins and spread of Campylobacter strains contaminating the environment and will determine their contribution to human campylobacteriosis morbidity, as well as the underlying (non-foodborne) transmission routes. As a collaboration of 4 leading institutes in public, animal and environmental health in the Netherlands (RIVM, CVI, UU and Alterra WUR), we will collect and type with a gene-by-gene approach (whole-genome multilocus sequence typing, wg-MLST) over 1200 C. jejuni/coli isolates representative of the Dutch eco-epidemiological situation from human cases, surface water (agricultural ditches, recreational waters, wastewater outlets), animals (broilers, layers, beef/dairy cattle, sheep/goats, pigs, pets), and wild birds (Anseriformers, Charadriformes, Columbiformes, Suliformes) using both well-established surveillance systems and ad hoc sampling schemes. We will: (i) characterize genotypically the strains circulating in surface water, animals and humans; (ii) quantify the contribution of different wild bird, farm and companion animals to Campylobacter pollution in different surface water types, seasons and areas with varying human, livestock and wild bird densities; (iii) quantify the contribution of different animal reservoirs and surface water to human campylobacteriosis in different seasons and areas with varying human, livestock and wild bird densities to estimate both the fraction of human cases attributable to the environment and the relation between human cases and reservoir density; (iv) determine the evolutionary history and relations of Campylobacter strains in the environment, humans and animals to understand their diversity and ecology, identify source-specific genetic markers, examine the role of the environment in the emergence of pathogenic strains, and perform source attribution at a high resolution; (v) conduct combined source attribution and case-control analyses to identify risk exposures for human campylobacteriosis of environmental origin and its underlying transmission routes. By depicting the epidemiology of non-foodborne campylobacteriosis, this project will allow for the delineation of more holistic control strategies, including those preventing Campylobacter dissemination into the environment. Besides standard scientific outputs, the results of this project will be translated into practical action points and advices for regulatory authorities on how to tackle environmental campylobacteriosis. The project members host national/international Campylobacter reference labs and participate since many years in advisory groups for the Dutch Ministries of Health and Economic Affairs, as well as the poultry industry, so through these forums knowledge gained in this project will be translated into interventions.

ASAP - Antimicrobial Stewardship And Pets 01.11.2014 to 30.11.2017
General project description

In Nederland is de afgelopen jaren bij landbouwhuisdieren een aanzienlijke reductie in het antibioticumgebruik gerealiseerd. Bij gezelschapsdieren is er minder aandacht voor dit probleem geweest, ondanks het feit dat  overdracht van (multiresistente) bacteriën tussen deze dieren en hun baasjes aannemelijk is door het nauwe contact dat zij hebben. Onderzoek toont aan dat er bij honden en katten relatief veel 3e keuze middelen gebruikt worden, terwijl dit antibiotica zijn die juist met grote terughoudendheid gebruikt zouden moeten worden.


Welke overwegingen maakt een dierenarts bij de beslissing wel of geen antibiotica te gebruiken? En waar loopt een dierenarts tegenaan bij deze beslissing? Dit project beoogt antwoorden op deze vragen te krijgen en zal een programma ontwikkelen ter bevordering van verantwoord antibioticumgebruik bij gezelschapsdieren. Dit programma zal getest en geëvalueerd worden in 40 praktijken, waarna een plan voor grootschalige implementatie ontwikkeld zal worden.

General project description

De doelstellingen van het Project Monitoring Zoönosen Gezelschapsdieren zijn het volgen van trends en het oppikken van ongebruikelijke signalen betreffende zoönosen en antimicrobiële resistentie bij gezelschapsdieren. Hiervoor worden twee bronnen gebruikt: de meldingen die binnenkomen via de telefonische help- en melddesk, en de informatie uit de routinediagnostiek van het Veterinair Microbiologisch Diagnostisch Centrum (VMDC). Onder andere door het analyseren van de trends in voorkomen van zoönotische agentia uit het lab informatie systeem. Voor bijzondere gevallen kan aanvullende diagnostiek ingezet worden. Tot slot maakt deelname aan het Signaleringsoverleg en het (mede) opstellen van VetInfect berichten deel uit van het project.
