Abstract
Enterococcus species are significant intestinal commensals of animals, including poultry. However, they have emerged as important opportunistic infective agents in both veterinary and human medicine as well as major nosocomial pathogens, owing to their increasing antimicrobial resistance. This research aimed to investigate the prevalence and antimicrobial resistance patterns of Enterococcus spp. isolated from poultry farms in the north of Serbia. A total of 40 samples of overshoes or feces were collected from 40 poultry farms and analyzed for the presence of Enterococcus spp. using PCR or MALDI-TOF mass spectrometry for their identification. The number of isolates was 40 and included 11 isolates from laying hens, 2 isolates from turkeys, 3 from broiler breeders, and 24 from broilers. The Kirby-Bauer disk diffusion method was used to test for antibiotic susceptibility in accordance with the Clinical and Laboratory Standards Institute and EUCAST guidelines. The results showed that Enterococcus faecalis was isolated from 37.5% farms, and E. faecium from 42.5%. E. hirae was identified in 15% of poultry establishments, and E. durans and E. thialandicus on 2.5%. Notably, resistance to erythromycin, streptomycin, fluoroquinolones, and tetracyclines among the frequently used antibiotics was found. Furthermore, 35% of the isolates had multidrug resistance (MDR). In order to prevent the spread of antibiotic resistance in chicken farming and protect the health of the public and animals alike, our findings highlight the critical need for improved surveillance and control measures. To effectively establish a containment strategy for Enterococcus spp. isolated from poultry farms, more research into the processes behind their antibiotic resistance is required.

Antibiotics (Basel) 2022; 11:1650.

Abstract
Poultry litter is widely used worldwide as an organic fertilizer in agriculture. However, poultry litter may contain high concentrations of antibiotics and/or antimicrobial-resistant bacteria (ARB), which can be mobilized through soil erosion to water bodies, contributing to the spread of antimicrobial resistance genes (ARGs) in the environment. To better comprehend this kind of mobilization, the bacterial communities of four ponds used for irrigation in agricultural and poultry production areas were determined in two periods of the year: at the beginning (low volume of rainfall) and at the end of the rainy season (high volume of rainfall). 16S rRNA gene sequencing revealed not only significantly different bacterial community structures and compositions among the four ponds but also between the samplings. When the DNA obtained from the water samples was PCR amplified using primers for ARGs, those encoding integrases (intI1) and resistance to sulfonamides (sul1 and sul2) and β-lactams (blaGES, blaTEM and blaSHV) were detected in three ponds. Moreover, bacterial strains were isolated from CHROMagar plates supplemented with sulfamethoxazole, ceftriaxone or ciprofloxacin and identified as belonging to clinically important Enterobacteriaceae. The results presented here indicate a potential risk of spreading ARB through water resources in agricultural areas with extensive fertilization with poultry litter.

Abstract
Farmers apply broiler chicken litter to soils to enrich organic matter and provide crops with nutrients, following varying periods of stockpiling. However, litter frequently harbors fecal-derived microbial pathogens and associated antibiotic resistance genes (ARGs), and may be a source of microbial contamination of produce. We coupled a cutting-edge Loop Genomics long-read 16S rRNA amplicon-sequencing platform with high-throughput qPCR that targeted a suite of ARGs, to assess temporal (five time points over a 60-day period) and spatial (top, middle and bottom layers) microbiome and resistome dynamics in a broiler litter stockpile. We focused on potentially pathogenic species from the Enterobacteriaceae, Enterococcaceae and Staphylococcaceae families associated with food-borne disease. Bacterial diversity was significantly lower in the middle of the stockpile, where targeted pathogens were lowest and Bacillaceae were abundant. E. coli was the most abundant Enterobacteriaceae species, and high levels of the opportunistic pathogen Enterococcus faecium were detected. Correlation analyses revealed that the latter was significantly associated with aminoglycoside (aac(6′)-Ib(aka aacA4), aadA5), tetracycline (tetG), vancomycin (vanC), phenicol (floR) and MLSB (mphB) resistance genes. Staphylococcaceae were primarily non-pathogenic, but extremely low levels of the opportunistic pathogen S. aureus were detected, as was the opportunistic pathogen S. saprophyticus, which was linked to vancomycin (vanSA, vanC1), MLSB (vatE, ermB) and tetracycline (tetK) resistance genes. Collectively, we found that stockpile microbiomes and resistomes are strongly dictated by temporal fluctuations and spatial heterogeneity. Insights from this study can be exploited to improve stockpile management practice to support sustainable antimicrobial resistance mitigation policies in the future.

Abstract
Aim: This study was conducted to isolate generic enterobacteria from day-old broiler chicks in Nigeria, determine the antibacterial resistance profile, and assess multidrug resistance. Materials and Methods: The birds were sourced from five purposively-selected hatcheries (identified as A, B, C, D and E) in Southwest Nigeria. Non-duplicate cloacal swabs were collected from a total of 75 (15 birds per hatchery) randomly selected apparently healthy birds. Sampling was done in three batches of five chicks per batch at 2-week interval. Isolation of enterobacteria was done using MacConkey agar. The resistance of the isolates was determined using the disk diffusion method. Results: Of 15 processed samples of birds from each hatchery, all samples from hatcheries B, D, and E, 10 (66.7%) and 14 (93.3%) samples from hatcheries A and C, respectively, yielded pure cultures of Escherichiacoli. Klebsiella was also isolated from 1 (7.1%) of the 14 and 2 (13.2%) of the 15 growth-positive samples from hatcheries C and D, respectively. The range of resistance among E. coli isolates was tetracycline (86.7-100%), ampicillin (80-100%), gentamicin (60-85.7%), sulfamethoxazole-trimethoprim (46.7-92.9%), enrofloxacin (40-100%), ciprofloxacin (26.7-86.7%), streptomycin (10-80%), cefotaxime (26.7-73.3%), amoxicillin-clavulanic acid (13.3-60%), and ceftazidime (6.7-40%). Klebsiella and all E. coli isolate from chicks of hatcheries B, C, and E, 80 and 93.3% of those from chicks of hatcheries A and D, respectively, exhibited resistance to three or more classes of antibacterial agents. Conclusion: Commercial day-old broiler chicks in Nigeria are colonized by multidrug-resistant coliforms (E. coli and Klebsiella) and are potential reservoirs and disseminators of these organisms.

Abstract
Tetracyclines, sulfonamides and amphenicols are broad spectrum antimicrobial drugs that are widely used in poultry farming. However, a high proportion of these drugs can be excreted at high concentrations in droppings, even after the end of a therapy course. This work intended to assess and compare concentrations of florfenicol (FF), florfenicol amine (FFa), chlortetracycline (CTC), 4-epi-chlortetracycline (4-epi-CTC), and sulfachloropyridazine (SCP) in broiler chicken droppings. To this end, 70 chickens were housed under controlled environmental conditions, and assigned to experimental groups that were treated with therapeutic doses of either 10% FF, 20% CTC, or 10% SCP. Consequently, we implemented and designed an in-house validation for three analytical methodologies, which allowed us to quantify the concentrations of these three antimicrobial drugs using liquid chromatography coupled to mass spectrometry (LC-MS/MS). Our results showed that FF and FFa concentrations were detected in chicken droppings up to day 10 after ceasing treatment, while CTC and 4-epi-CTC were detected up to day 25. As for SCP residues, these were detected up to day 21. Noticeably, CTC showed the longest excretion period, as well as the highest concentrations detected after the end of its administration using therapeutic doses.

Abstract
Plasmid mediated Extended Spectrum Beta-Lactamase and AmpC Beta-Lactamase (ESBL/pAmpC) producing bacteria are resistant to beta-lactam antimicrobials and are widespread in humans, the environment and animals. Animals, especially broilers, are an important reservoir of ESBL/pAmpC producing bacteria. To control ESBL/pAmpC prevalence in broilers, transmission within the entire broiler production pyramid should be considered. This study, including 103 articles originating from two electronic databases, searched for evidence for possible routes of transmission of ESBL/pAmpC producing bacteria in the broiler production pyramid. Possible routes of transmission were categorised as 1) vertical between generations, 2) at hatcheries, 3) horizontal on farm, and 4) horizontal between farms and via the environment of farms. This review presents indications for transmission of ESBL/pAmpC producing bacteria for each of these routes. However, the lack of quantitative results in the literature did not allow an estimation of the relative contribution or magnitude of the different routes. Future research should be specifically targeted towards such information as it is crucial to guide reduction strategies for the spread of ESBL/pAmpC producing bacteria in the broiler production chain.

Abstract
The objective of this study was to evaluate the effects of different types of flooring designs on antimicrobial resistance in commensal Escherichia coli from turkeys treated with enrofloxacin. Two trials were performed with same feed, housing conditions and fattening duration, but with different flooring designs. Furthermore, the first trial was performed in an unchanged environment and the second trial in a changed environment. The flooring designs of the pens were assigned to four groups; G1 - entire floor pen covered with litter, G2 - floor pen with heating, G3 - partially slatted flooring including an area that was littered, G4 - fully slatted flooring with a sand bath. Enrofloxacin was given at days 10-14 via drinking water. The changed environment in the second trial was achieved by moving the animals to new pens with the respective same conditions as previously after antimicrobial administration at day 15. A total of 576 E. coli were isolated from cloacal swab and poultry manure samples. Sample collection was done before the treatment, after the treatment and at the end of the trials at day 35. The resistance of isolates to enrofloxacin and ampicillin was determined using broth microdilution A single treatment with enrofloxacin reduced the proportion of samples with susceptible E. coli isolates significantly in all flooring designs. Overall, frequencies of enrofloxacin resistance were significantly different between the unchanged and changed environment. At the same time, the proportion of ampicillin-resistant isolates increased in the first trial, although no ampicillin was applied in this study.
