Hyper-Aerotolerant Campylobacter coli From Swine May Pose a Potential Threat to Public Health Based on Its Quinolone Resistance, Virulence Potential, and Genetic Relatedness
In conclusion, quinolone resistance of C. coli may be distributed throughout in all swine groups in farms. HAT C. coli is likely to remain in pig farms and re-infect other pigs in the farms. Furthermore, swine-derived HAT C. coli could be transmitted to humans easily through the food chain owing to its aerotolerance, and it could pose a threat to public health owing to its high-level ciprofloxacin resistance and virulence. This study highlights the need to develop management practices that prevent the transmission of swine-derived HAT C. coli to humans.

Distribution of Salmonella Serovars and Antimicrobial Susceptibility from Poultry and Swine Farms in Central Vietnam
This study was conducted to estimate the prevalence of Salmonella spp. and their antimicrobial susceptibilities on poultry and swine farms, sampled in 2 regions in Central Vietnam. A total of 67 poultry farms and 46 swine farms were sampled in a period of 5 months (from September 2012 to January 2013). Salmonella spp. was prevalent in 46.3% and 71.7% of poultry and swine farms, respectively. Altogether, 99 non‐typhoidal Salmonella were isolated and the most common serovars were Salmonella Weltevreden (19%), followed by Salmonella Typhimurium (12%) and Salmonella 4,[5],12:i:‐ (11%). Overall, 71 of 99 (72%) Salmonella i...

Enterobacteria associated with houseflies (Musca domestica) as an infection risk indicator in swine production farms.
Abstract
Houseflies (Musca domestica) spend part of their life development on animal or human manure. Manure is high in pathogenic microbes; thus, houseflies have been known as a mechanical vector for various important zoonotic diseases. Therefore, the present study showcases captured houseflies from intensive swine production regions (which are areas of high manure concentration) in Southern Brazil, and analyzes their bodies' to the presence of Escherichia coli and Salmonella sp. and the sensitivity of these bacteria to various antibiotics. Additionally, Quantitative Microbiology Risk Assessment was performed sim...

A Japanese trial to monitor methicillin-resistant Staphylococcus aureus (MRSA) in imported swine during the quarantine period
Conclusions MRSA ST398 isolates were obtained from imported swine in this first trial to monitor MRSA during the quarantine period in Japan. For the One Health approach against antimicrobial resistance, monitoring imported animals and generating feedback data would be important.

Identification and prevalence of RND family multidrug efflux pump oqxAB genes in Enterococci isolates from swine manure in China.
CONCLUSION: This is the first time that the oqxAB genes have been identified in Enterococcus faecalis from swine manure. The genetic linkage of oqxAB-aph(3')-IIa in Enterococcus has not been described before. The high prevalence of oqxAB genes in Enterococcus suggests that it may constitute a reservoir for oqxAB genes and pose a potential threat to public health.

Elimination of veterinary antibiotics and antibiotic resistance genes from swine wastewater in the vertical flow constructed wetlands.
Abstract
This paper investigated the efficiency of two vertical flow constructed wetlands characterized by volcanic (CW1) and zeolite (CW2) respectively, at removing three common antibiotics (ciprofloxacin HCl, oxytetracycline HCl, and sulfamethazine) and tetracycline resistance (tet) genes (tetM, tetO, and tetW) from swine wastewater. The result indicated that the two systems could significantly reduce the wastewater antibiotics content, and elimination rates were in the following sequence: oxytetracycline HCl>ciprofloxacin HCl>sulfamethazine. The zeolite-medium system was superior to that of the volcanic-m...

Characterization of swine isolates of Clostridium difficile in Spain: a potential source of epidemic multidrug resistant strains?
We present the first report on the ribotype distribution and antimicrobial susceptibility of C. difficile in swine in Spain. A total of 144 isolates were PCR ribotyped, and their MIC values for 13 antimicrobial agents were determined using the Etest. Toxin A and B production was assessed using a commercial immunoassay and, in the case of toxin B, a specific cytotoxicity test. Our results show a high prevalence of the toxigenic 078 ribotype (94.4%) and multidrug resistance (49.3%) among the studied isolates. A minority of isolates (5.6%) belonged to a mostly non-toxinogenic ribotype. All isolates were resistant to the fluor...

Antimicrobial susceptibility of Streptococcus suis isolated from clinically healthy swine in Brazil.
This study is the first to report on the antimicrobial susceptibility of S. suis isolated from clinically healthy pigs in Brazil; the fourth major pork producer in the world. The antimicrobial susceptibility of 260 strains was determined by disc diffusion method. Strains were commonly susceptible to ceftiofur, cephalexin, chloramphenicol, and florfenicol, with more than 80% of the strains being susceptible to these antimicrobials. A high frequency of resistance to some of the antimicrobial agents was demonstrated, with resistance being most common to sulfa-trimethoprim (100%), tetracycline (97.69%), clindamycin (84.61%), n...

Identification of Plasmid-Mediated Quinolone Resistance in Salmonella Isolated from Swine Ceca and Retail Pork Chops in the United States.
Abstract
Fluoroquinolones are important antimicrobial drugs used to treat human Salmonella infections, and resistance is rare in the United States for isolates from both human and animal sources. Recently, a number of Salmonella isolated from swine cecal contents and retail pork products from NARMS surveillance exhibited decreased susceptibility to ciprofloxacin. We identified two qnrB19 quinolone resistance plasmids as predominantly responsible for this phenomenon, and found them distributed among several Salmonella serotypes isolated throughout the United States.

Prevalence of cfr in Enterococcus faecalis strains isolated from swine farms in China: Predominated cfr-carrying pCPPF5-like plasmids conferring "non-linezolid resistance" phenotype.
In conclusion, the cfr gene which had no linezolid resistance phenotype was present in multidrug-resistance E. faecalis strains, and the clonal spread of ST475 and ST16 strains and the horizontal transfer of the pCPPF5-like plasmids have contributed to the dissemination of cfr.

Occurrence and distribution of veterinary antibiotics and tetracycline resistance genes in farmland soils around swine feedlots in Fujian Province, China.
Abstract
Six antibiotics, tetracyclines (TCs), and quinolones (QNs) in farmland soils from four coastal cities in Fujian Province of China were investigated. Oxytetracycline was most frequently detected, followed by enrofloxacin, ciprofloxacin, chlorotetracycline, ofloxacin, and tetracycline, with maximum concentrations of 613.2, 637.3, 237.3, 2668.9, 205.7, and 189.8 μg kg(-1), respectively. Samples from Putian City contained the highest maximum concentration of ∑TCs (3,064.2 μg kg(-1)), whereas those from Fuzhou City contained the highest maximum concentration of ∑QNs (897.8 μg kg(-1)). It is notewor...

Antimicrobial profile of Salmonella enterica serotype Choleraesuis from free-range swine in Kakamega fish market, western Kenya
Conclusions: The isolated S. Choleraesuis were resistant to more than 10% of the antimicrobial agents used in this study. Appropriate surveillance is warranted to gain more information about the epidemiology, as stopping antibiotics in animal feed would have economic implications for the industry.
