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.

204 Research paper – Saraz – 2018 – Study regarding seasonal incidence of fluoroquinolons in cow raw milk and their relationship with somatic cells count

In Significant Impact Groups: Other
Species targeted: Dairy;
Age: Adult;
Summary:
This study aimed to investigate the incidence of fluoroquinolone residues in raw cow milk and to evaluate the relationship between these residues and somatic cell count (SCC) value during summer and winter season. The study was carried out in the period May 2016 – June 2017, on 360 milk samples obtained from three farms from north-western Romania. The samples were analysed by LC-MS/MS method. Out of all samples, 67.50% of samples were positive for fluoroquinolone residues. The examined samples presented values below the recommended maximum residue limit (MRL). Enrofloxacin and its indicator residue, i.e. ciprofloxacin were the most frequently determined. The results of the study indicate that incidence of fluoroquinolone residues in winter season was higher than in summer. Also, SCC value was higher for milk samples with positive antibiotic residue. Our investigations denote that fluoroquinolones are frequently administered to the dairy cows despite of the EU and national recommendations.

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.

Species targeted: Dairy;
Age: Adult;
Summary:
The aim of this study was to analyze the prevalence of clinical mastitis in a dairy farm and the economic implications of this condition during 8 months. Based on the clinical signs, 37% of lactating cows were diagnosed with mastitis and 29 % of these shows relapse. The economic loss due to the compromised lactation and the medical treatment was amounted to almost 25000 Euro / 8 months. The results of the statistical study performed in this work raised an alarm and highlighted the need of introducing control programs, early diagnosis and mastitis prevention.

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.

200 Research paper – Herman – 2018 – Evaluation of propolis for antibacterial activity in vitro

In Significant Impact Groups: Specific alternatives \ Other
Species targeted: Other;
Summary:
The antimicrobial action of the propolis tincture was tested on six bacterial strains. Raw propolis tincture produced the inhibition of the growth of bacterial cultures for four of the bacterial strains studied. For two of the bacterial strains studied, propolis tincture produced no inhibition of the growth of bacterial cultures. The investigations performed in this study demonstrated that the propolis tincture in vitro has antibacterial effect. The results from this study indicate a possible action of the propolis tincture, which can be used as a local treatment (to some extent), for various bacterial diseases in animals.

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.

In Significant Impact Groups: AMU reduction strategies \ Pathogen management
Species targeted: Pigs;
Age: Young;
Summary:
The present study explored whether the use of group medication with antibiotics in a Danish pig herd was reduced after vaccination of the pigs against proliferative enteropathy (PE) caused by Lawsonia intracellularis. 7900 pigs originating from a single commercial sow herd were vaccinated against L. intracellularis, whereas 7756 pigs were kept as non-vaccinated controls. The pigs were included batch-wise in the study with every second batch being vaccinated. In the vaccinated batches, the consumption of oxytetracykline to treat PE was reduced by 79%, with a significantly lower number of pigs being treated. Vaccination also resulted in a highly significant improvement of average daily weight gain (+ 46 g/day) and carcass weight (+ 1.25 kg) as well as a shortened fattening period (-8 days).

In Significant Impact Groups: Prudent use AB \ Pharmaceuticals; Pathogen management
Species targeted: Pigs;
Age: Young;
Summary:
Vaccination has been suggested as a strategy to prevent disease and minimise the need for antimicrobial treatments. The aim of this study was to assess the associations between data on vaccination, productivity and AMU in Danish finisher herds over a 4-year period. Finisher herds (N = 40–62) with register data on productivity (i.e. average daily weight gain, feed conversion rate, mortality and lean meat percentage) and data on prescriptions of antimicrobials measured in Animal Daily Doses/100 finishers/day as well as the proportion of parenteral AMU treatments out of all treatments (AMU-ratio) were included. Vaccination against PRRS and higher AMU for finishers were associated with increased lean meat percentage. Vaccination against PCV2, PRRS and APP were associated with higher levels of AMU, and vaccination against Lawsonia with a higher AMU-ratio. This may be explained as some farmers preferring to take action soon after observing disease problems.

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.
