“…Furthermore, fecal samples contain inhibitors that can impair DNA or RNA extraction success. For instance, a direct PCR method has lower sensitivity than the modified gram staining method for detecting Arcobacter in a human stool sample (Dermani et al, 2017).…”

Pigs can have Arcobacter butzleri. However, information on A. butzleri in Thai pigs remains scarce. This work aimed to survey A. butzleri in healthy pigs and assess their antimicrobial susceptibility, potential transferrable antimicrobial resistance (AMR) genes, and virulence-associated genes (VAGs). Cross-sectional fecal samples of 203 pigs from 18 farms were cultured and molecularly identified. A. butzleri prevalence in all pigs was (31/203; 15.3%): nursery (0/8; 0%), finisher (27/144; 18.8%), and sow (4/51; 7.8%). The total farm A. butzleri prevalence was 50%: nursery (0/2: 0%), finisher (8/14: 57.1%), and sow (2/9: 22.2%) farms. From the 10 antibiotic disks evaluated, the isolates were mostly sensitive to imipenem (96.8%), tetracycline (83.9%), streptomycin (67.7%), and amoxycillin/clavulanic acid (54.8%); however, they were mostly resistant to cefotaxime (98.6%), sulbactam/cefoperazone (71%), ampicillin (67.7%), enrofloxacin (48.4%), and fosfomycin (42.9%) and were neither sensitive nor resistant to erythromycin. Most multidrug resistance patterns in this study were in four to six classes. Three isolates resisted all 10 antibiotics. However, only the TetO gene was detected in one isolate, whereas ESBLs (SHV, CTX-M, and TEM), PMQRs (qnrA, qnrS, qnrB, oqxAB, and aac(6’)-Ib-cr), ermB, and mefA genes were not found in any isolates. The rankings of VAGs presented in the isolates were ciaB (100%), mviN (97%), pldA (93%), tlyA (90%), cj1349 (90%), cadF (83%), hecB (10%), hecA (7%), and irgA (0%), and most isolates carried six VAGs (77%). A. butzleri is present in healthy pigs, and this database is the first to show A. butzleri VAG and AMR genes in Thai pigs

The Arcobacteraceae bacterial family includes species isolated from animals and related food products. Moreover, these species have been found in other ecological niches, including water. Some species, particularly Arcobacter butzleri and Arcobacter cryaerophilus, have been isolated from human clinical cases and linked to gastrointestinal symptoms. The presence of antibiotic-resistant strains is a concern for public health, considering the possible zoonoses and foodborne infections caused by contaminated food containing bacteria resistant to antibiotic treatments. This review aims to highlight the importance of antibiotic resistance in Arcobacter spp. isolates from several sources, including information about antibiotic classes to which this bacterium has shown resistance. Arcobacter spp. demonstrated a wide spectrum of antibiotic resistance, including several antibiotic resistance genes. Antibiotic resistance genomic traits include efflux pumps and mutations in antibiotic target proteins. The literature shows a high proportion of Arcobacter spp. that are multidrug-resistant. However, studies in the literature have primarily focused on the evaluation of antibiotic resistance in A. butzleri and A. cryaerophilus, as these species are frequently isolated from various sources. These aspects underline the necessity of studies focused on several Arcobacter species that could potentially be isolated from several sources.
