“…These results are in concordance with previous studies where these six genes were predominantly detected with prevalence values ranging between 72.6% and 100% Douidah et al, 2012;Karadas et al, 2013). Tabatabaei et al (2014) previously highlighted the high prevalence of the ciaB and mviN genes, significantly more prevalent than other virulence markers. These two virulence determinants, the invasive protein CiaB and MviN factor, share homology with those of C. jejuni.…”

“…An important factor to be taken into account for risk assessment is to determine the occurrence of Arcobacter strains possessing pathogenicity markers (Tabatabaei et al, 2014). For this purpose, in this study, PCR assays were performed to investigate the presence and distribution of ten putative virulence genes in Arcobacter spp.…”

“…Douidah et al (2012) and Karadas et al (2013) developed PCR assays for the detection of all these virulence genes in Arcobacter, proving their presence in A. butzleri, A. cryaerophilus and A. skirrowii. Since then, few studies have analysed the occurrence of putative virulence genes in Arcobacter species isolated from humans and animal food sources Ferreira et al, 2014;Lehmann et al, 2015;Levican et al, 2013;Tabatabaei et al, 2014). There is a need for further information in this regard; thus, it would be interesting to expand the range of food sources tested.…”

The aim of this study was to perform the identification and molecular characterization of Arcobacter cryaerophilus and Arcobacter butzleri isolated from caiman (Caiman yacare), kept at a production farm, in Brazil. Forty fecal samples were analyzed. After isolation and identification, 21/40 strains of A. butzleri and 19/40 strains of A. cryaerophilus were subjected to PCR for potential virulence gene detection. The results of the PCR showed 38/40 strains positive for the cadF, cj1349, ciaB, and tlyA genes, 39/40 strains positive for the pldA gene, and 40/40 strains positive for the mviN gene. None of the strains presented the irgA gene. Hemagglutinin (hecA gene) and hemolysin (hecB) genes were detected in 21/40 and 16/40 strains, respectively. The SE-AFLP showed a great genetic diversity, but some clonally groups were disseminated in various tanks. These data reveal that the strains presented the same virulence traits described from Arcobacter isolated from food-borne disease in humans.

“…Functions of the different genes include: cadF gene and cj1349 gene code for outer membrane proteins facilitating intestinal epithelial cell to cell contact by adhering to fibronectin; ciaB gene is involved in invasion of host cell, pldA gene codes for outer membrane phospholipase A which hydrolyzes acyl ester bonds, tlyA gene is a hemolysin gene, irgA gene codes for an outer membrane receptor for enterobactin, hecA gene is a member of filamentous hemagglutinin family and hecB gene codes for hemolysin activation protein (Douidah et al 2012). A study conducted by Tabatabaei et al (2014) in Southern Iran revealed six virulence genes (cadF, ciaB, cj1349, mviN, pldA and tlyA) in Arcobacter spp. These six genes were present in all the A. butzleri isolates.…”

Arcobacter has emerged as an important food-borne zoonotic pathogen, causing sometimes serious infections in humans and animals. Newer species of Arcobacter are being incessantly emerging (presently 25 species have been identified) with novel information on the evolutionary mechanisms and genetic diversity among different Arcobacter species. These have been reported from chickens, domestic animals (cattle, pigs, sheep, horses, dogs), reptiles (lizards, snakes and chelonians), meat (poultry, pork, goat, lamb, beef, rabbit), vegetables and from humans in different countries. Arcobacters are implicated as causative agents of diarrhea, mastitis and abortion in animals, while causing bacteremia, endocarditis, peritonitis, gastroenteritis and diarrhea in humans. Three species including A. butzleri, A. cryaerophilus and A. skirrowii are predominantly associated with clinical conditions. Arcobacters are primarily transmitted through contaminated food and water sources. Identification of Arcobacter by biochemical tests is difficult and isolation remains the gold standard method. Current diagnostic advances have provided various molecular methods for efficient detection and differentiation of the Arcobacters at genus and species level. To overcome the emerging antibiotic resistance problem there is an essential need to explore the potential of novel and alternative therapies. Strengthening of the diagnostic aspects is also suggested as in most cases Arcobacters goes unnoticed and hence the exact epidemiological status remains uncertain. This review updates the current knowledge and many aspects of this important food-borne pathogen, namely etiology, evolution and emergence, genetic diversity, epidemiology, the disease in animals and humans, public health concerns, and advances in its diagnosis, prevention and control.
