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.

In Significant Impact Groups: Biosecurity \Internal biosecurity Materials
Species targeted: Other;
Age: Not stated;
Summary:
Many of the commercial substances used to clean surfaces, instruments, medical devices or industrial machinery are corrosive to metals, cause irritation to the skin, mucous membranes or even show a toxic and carcinogenic effect. For these reasons, it has been necessary to find solutions for combating or preventing the formation of biofilms on surfaces. In recent years, there has been a lot of interest in the use of organic acids for this purpose. This group of substances exerts an antibacterial effect at certain pH values and acts by changes in the cell wall of the bacteria. In the present paper, the efficacy of some organic acids (citric acid, malic acid and ADABLINE ALK product), on bacterial cells and those present in biofilms, on 3 bacterial species from the group of Gram negative bacteria (Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa) and a Gram-positive one (Staphylococcus aureus) was evaluated, with varying results.

In Significant Impact Groups: AMU reduction strategies \ Monitoring and surveillance; Antibiotic use
Species targeted: Dairy;
Summary:
The aim of this paper was to determine the presence or absence of antibiotic residues in dairy milk, to assess the most frequently encountered antibiotic classes and to establish a correlation between positive samples and various milk quality parameters: the somatic cell count (SCC), the total number of germs (TNG) as well as protein, fat and lactose in the samples included in the study. The research was carried out on a total number of 360 samples between 2016 and 2017 (10 samples of milk were taken each month from the three farms included in our experiments -farm A, farm B, farm C. The main classes of identified antibiotics were: fluoroquinolones, macrolides, tetracyclines and quinolones. In 11 samples, the presence of antibiotic residues was detected above the maximum admissible limit. In positive samples, the number of somatic cells as well as the total number of germs increased.

In Significant Impact Groups: AMU reduction strategies \ Monitoring and surveillance; Disease/health
Species targeted: Poultry;
Summary:
Aim of this study was to determine of the antimicrobial resistance of Escherichia coli strains from flocks belonging to a unit integrated consumer egg production. For that purpose, E. coli strains isolated from colibacillosis outbreaks or obtained by routine surveillance were tested for antibiotic susceptibility. Samples were divided into four categories: breeding of light breeds, incubation, youth and laying hens. Isolated strains were resistant to spectinomicin, flumequin, erythromycin, trimethoprim, oxytetracycline, ampicillin, amoxicillin, enrofloxacin, doxicillin and sensitive to fosfomycin +tylosin, ceftiofur, lincomycin + spectinomycin, colistin, gentamycin, florfenicol and neomycin. As a conclusion, even though antibiotics are used to a lesser extent in chicken flocks for egg consumption compared to poultry meat production, this study found the resistance of E. coli strains to different antibiotics and multi-drug resistant strains were identified as well.

195 Research paper – Maesaar- 2016 – Antimicrobial Resistance Profiles of Campylobacter spp Isolated from Broiler Chicken Meat of Estonian Latvian and Lithuanian Origin at Estonian Retail

In Significant Impact Groups: AMU reduction strategies \ Monitoring and surveillance Disease/health
Species targeted: Poultry;
Age: Not stated;
Summary:
This study shows that antimicrobial susceptibility results indicate that the use of antimicrobial agents, particularly fluoroquinolones, in Estonian broiler chicken production has been reduced during recent years. This can be associated with the policies in restrictive use of antimicrobials implemented by the European Commission in 2006. Resistances to one or more antimicrobials occurred significantly less frequently in the products of Estonian origin than in the products of Latvian and Lithuanian origin available at Estonian retail. It was found that problems caused by the inappropriate use of antimicrobials extend beyond the country in which a food originates; therefore, the origin of broiler chicken meat may pose different risks for human population.

In Significant Impact Groups: AMU reduction strategies \ Monitoring and surveillance Disease/health
Species targeted: Dairy;
Age: Young;
Summary:
In this study 180 samples collected from 18 Latvian farms, to detect the prevalence and antimicrobial resistance of Escherichia coli, Enterococcus spp., Listeria monocytogenes, Yersinia enterocolitica, Salmonella spp., Staphylococcus aureus, and Campylobacter spp. Among all, 64% E. coli, 100% Enterococcus faecalis and 96% Enterococcus faecium isolates were resistant at least to one antibiotic. The prevalence of extended-spectrum b-lactamase (ESBL)/AmpC-positive E. coli were 11.1%. Campylobacter jejuni and Campylobacter coli were the most resistant to tetracycline and fluoroquinolones. Prevalence of L. monocytogenes was 0.6% and S. aureus 1.7%. Farm size, bought calves, contact with other calves, and antimicrobial treatment of cows were associated with increased prevalence of resistant E. coli and Enterococcus spp. Despite low usage of antimicrobials in Latvia, high rates of antimicrobial resistance in fecal indicators and Campylobacter, combined with high prevalence of ESBL-positive E. coli, show the necessity for the prudent use of antimicrobials in dairy farms in Latvia.

In Significant Impact Groups: AMU reduction strategies \ Monitoring and surveillance Disease/health
Species targeted: Pigs; Poultry; Dairy; Beef; Sheep;
Age: Not stated;
Summary:
This study reports the prevalence and antimicrobial resistance of Salmonella isolates from meat in Latvia. A total of 3,152 samples of raw and ready-to-eat (RTE) meats were collected during the official control and in-house control procedures in 2015. The prevalence of Salmonella was 0.8%. The highest prevalence (1.5%) of Salmonella was found in minced meat and meat preparations, while the lowest (0%) in frozen meat and meat preparations and RTE meats. Most common were S. Typhimurium (36%) and S. Derby (32%). In total, 62% of Salmonella isolates were resistant to at least one antimicrobial. Altogether, 40% of isolates were resistant to sulfamethoxazole, 25% to nalidixic acid, ciprofloxacin, ampicillin and 20% to tetracycline. S. Typhimurium exhibited antimicrobial resistance more often (than other Salmonella serovars). The study shows that the presence of Salmonella in meat and the high prevalence of resistant strains, is a significant public health related issue in Latvia.
