Age: Young; Adult;
Summary:
Bacterial antimicrobial resistance (AMR) is constantly evolving and horizontal gene transfer through genetic elements known as plasmids plays a major role. The identification of plasmids characteristics and their association with humans and animals provides important information that is essential to understand the contribution of these genes to the transmission of resistance. The purpose of this review is to provide an overview of all known AMR related types of genetic elements (plasmids) in Enterobacteriaceae, the resistance genes they carry and their geographical distribution. This information is very important in the fight against antimicrobial resistance.

Species targeted: Pigs; Poultry; Sheep; Other;
Age: Young; Adult;
Summary:
Genes transferred by ColE1 plasmids are important vehicles for the spread of antibiotic resistance in two families of bacteria, Enterobacteriaceae and Pasteurellaceae. Their monitoring is essential, as they harbor important resistance elements that can lead to resistance to antimicrobials in bacteria found in humans, animals and the environment. Understanding how these genetic elements work can lead to better understanding of how resistance to antimicrobials is being spread. In this work we present a useful genetic tool for the detection and analysis of ColE1 plasmids, and confirm their important role in the dissemination of antibiotic resistance, especially in the Pasteurellaceae family of bacteria.

231 Research paper – Miguela-Villoldo – 2019 – National colistin sales versus colistin resistance in Spanish pig production

In Significant Impact Groups: AMU reduction strategies \ Monitoring and surveillance; Antibiotic use
Species targeted: Pigs;
Age: Young; Adult;
Summary:
Antimicrobials, particularly colistin, have been the first choice to control a certain type pf bacteria (Gram-negative) in pig production, and often used preventively. However, colistin is now considered to be a last resort antibiotic in human clinical practice. In 2015, the colistin resistance gene (mcr-1) was discovered in China. This mcr-1 gene was then reported in Southern Europe in 2016 in bacteria from farm animals (poultry and pigs). Currently, eight mcr genes have been reported (mcr-1 to 8)). In 2016, the EMA (European Medicine Agency) aimed to reduce use of colistin in animals in the European Union and a voluntary strategic plan to reduce colistin use in pigs was introduced in Spain. A total of 70% of Spanish pig production companies joined the program, representing 80% of Spanish pig production. The impact of these recommendations in the colistin resistance levels in pigs in Spain is reported in this article.

In Significant Impact Groups: AMU reduction strategies \ Monitoring and surveillance Disease/health
Species targeted: Poultry;
Age: Not stated;
Summary:
Antimicrobial usage is most common trigger for the spread of antimicrobial resistance however reducing antibiotic use only is not sufficient to reverse resistance. Only eliminating antimicrobial selection pressure does not lead to plasmid loss in all plasmid/host combinations. In 2012, a type of Salmonella bacteria (Salmonella Corvallis) carrying a multi-resistance gene (blaNDM-1 plasmid) was detected in a wild bird in Germany. In recent broiler chicken infection study, we observed transfer of this genetic element to other bacteria. The stability of this gene transfer was observed in our in vivo study with broilers. Our study revealed most common structural alterations of this relevant gene were maintained in the experiments with the broiler flock. Results in this article indicate that for the future, reduction in antimicrobial usage must be combined with alternative approaches that target the loss of the resistance gene, in order to slow down the spread of resistance.

210 Research paper – Milita – 2017 – Prevalence of antimicrobial resistance in commensal escherichia coli producing ESBLAMPC isolated from caecal samples of slaughered pigs in Romania

In Significant Impact Groups: AMU reduction strategies \ Monitoring and surveillance Disease/health
Species targeted: Pigs;
Age: Adult;
Summary:
The monitoring of the antimicrobial resistance of Escherichia coli commensal strains isolated from caecal samples collected from slaughtered pigs was implemented for the first time in Romania, in 2015, by testing a number of 399 samples. The prevalence of commensal ESBL/AmpC producing E. coli strains isolated from the slaughtered strains were resistant to cefotaxime (100%), ampicillin (100%), cefepime (91.93%), ceftazidime (90.13 %), sulfamethoxazole (73.54%), tetracycline (71.30 %), trimethoprim (62.33%), ciprofloxacin (53.81%), chloramphenicol (41.70%), nalidixic acid (39.91%), gentamicin (20.63%), cefoxitin (20.63%), azithromycin (14,35%), colistin (3.59%), ertapenem (1.79%). This survey shows that the pigs slaughtered in Romania during the year 2015 were colonized, in a proportion of more than 60%, with strains resistant to cephalosporins, sulfonamides, tetracyclines and fluoroquinolones. The results obtained will provide important insight into effects of using antimicrobials at animals.

In Significant Impact Groups: AMU reduction strategies \ Monitoring and surveillance Disease/health
Species targeted: Pigs; Poultry; Dairy; Beef; Sheep; Other;
Age: Not stated;
Summary:
At the European Commission (EC) level, legislation has been issued for the monitoring of antimicrobial resistance and these rules are applicable by each Member State (MS). For the proper implementation of the above legislation, audits are carried out in Member States that have developed programs on antimicrobial resistance that go beyond the EC’s requests. The aim of the study was the analysis of existing data reports, legislation and recommendations on antimicrobial resistance through which surveillance and monitoring is carried out in the European Union (EU). The audit reports issued between 2015 and 2017 by the Food Veterinary Office (FVO), as well as the articles issued by the EC through the antimicrobial resistance institutes were analysed. In conclusion, in order to improve antimicrobial resistance programs, a “good practice guide” can be achieved by MS with extensive experience in this area, to be used to harmonize antimicrobial resistance programs within the EU.

Age: Not stated;
Summary:
Chicken products may be a source of infection with pathogenic Escherichia coli strains (ExPEC) and may present a zoonotic risk through multiple antibiotic resistances. The emergence of multiple antibiotic resistances (resistance to three or more classes of antimicrobial agents) among E. coli strains isolated from birds has created major economic and human health problems. A total of 30 strains of E. coli have been isolated and identified from fresh chicken carcasses harvested at different time intervals over a period of 12 months from different manufacturers. Strains identified as E. coli were tested on 12 antimicrobial substances and showed multiple resistances. The highest resistance was recorded at erythromycin and doxycycline (96.6%), and the smallest resistance was recorded at gentamicin 10%. E. coli strains with multiple antibiotic resistances are one of the main cause of infections in humans and birds.

206 Research paper – Mesteaanu – 2018 – Study on the antibiotic resistance of strains of staphylococcus aureus isolated from animals with contagious ecthyma

In Significant Impact Groups: AMU reduction strategies \ Monitoring and surveillance; Disease/health
Species targeted: Sheep;
Age: Not stated;
Summary:
Staphylococcus aureus is a commonly found germ and cases of antibiotic resistance encountered due to the unusual use of antibiotics are frequently recorded in this germ. The results of the antibiogram showed an increased sensitivity to the action of gentamicin (96,6%) and of quinolones (ciprofloxacin 86.6%, enrofloxacin 83.3%) and trimethoprim (80%). The increase of the penicillin resistance phenomenon, widely used in the past, has led to new generations of antibiotics in this group (semi-synthetic penicillin). Based on the sensitivity of the strains of Staphylococcus aureus isolated in 7 types of antibiotics, it was computed the MAR index (multiple antibiotic resistance index), in order to establish the risk degree represented by these types of strains for animals and humans. The values of the MAR index showed a high likelihood of the occurrence of the multiple antibiotic resistance.

Summary:
Salmonella are major worldwide zoonotic pathogens infecting a wide range of animal species as well as humans. This study investigates the prevalence of circulating Salmonella serotypes in domestic and wild animal species in Romania and the spatial distribution of Salmonella isolates at county level in the period 2015-2016. There were collected 2551 samples for the isolation and serotyping of Salmonella according to ISO 6579:2002/Amd 1:2007 protocol. The findings of this study show that 36 Salmonella serotypes were isolated in 1357 Salmonella-positive samples in 2015, and 28 serotypes in 1188 Salmonella-positive samples in 2016. One sample from pigeon and one from hen were negative in 2015, and one sample from pigeon and three samples from hen were negative in 2016. In order to reduce the prevalence of serotypes with major zoonotic potential, we recommend continuing collaboration of all the professionals involved in the security of the food chain.
