“…In Bullman's study (2011a), 23.8% of Campylobacter-positive diarrhea samples were identified as C. ureolyticus, pointing to the potential role of these bacteria as an important enteric pathogen. This implication was confirmed by their further studies on C. ureolyticus pathogenicity and growth control imposed on the species present in the intestine (O'Donovan et al, 2014). Other studies indicated that this emerging pathogen can cause a gastrointestinal illness via destruction of cell structures (Garmory and Titball, 2004), relocating across the cell using various proteins such as zona occludens toxin (Zot) and secreted fibronectin-binding proteins (CadF and FlpA) (Bullman et al, 2013), or forming biofilms (Burgos-Portugal et al, 2012).…”

Genus Campylobacter has been recognized as a causative bacterial agent of animal and human diseases. Human Campylobacter infections have caused more concern. Campylobacters can be classified into two groups in terms of their original host: zoonotic and human oral species. The major zoonotic species are Campylobacter jejuni and Campylobacter coli, which mostly reside in the intestines of avian species and are transmitted to humans via consumption of contaminated poultry products, thus causing human gastroenteritis and other diseases as sequelae. The other campylobacters, human oral species, include C. concisus, C. showae, C. gracilis, C. ureolyticus, C. curvus, and C. rectus. These species are isolated from the oral cavity, natural colonization site, but have potential clinical relevance in the periodontal region to varying extent. Two species, C. jejuni and C. coli, are believed to be mainly associated with intestinal diseases, but recent studies suggested that oral Campylobacter species also play a significant role in intestinal diseases. This review offers an outline of the two Campylobacter groups (zoonotic and human oral), their virulence traits, and the associated illnesses including gastroenteritis.

“…ureolyticus is another emerging gastrointestinal pathogen (O'Donovan et al, 2014), which is also found in human oral abscesses (Man, 2011). In Bullman's study (2011a), 23.8% of Campylobacter-positive diarrhea samples were identified as C. ureolyticus, pointing to the potential role of these bacteria as an important enteric pathogen.…”

“…This represents the first report of C. ureolyticus in the faeces of patients presenting with gastroenteritis, suggesting a heretofore unreported role for this organism as an enteric pathogen. [72][73][74] Indeed, we showed that C. ureolyticus is second only to C. jejuni as the most common cause of Campylobacter associated gastroenteritis in Southern Ireland. 75 Furthermore, we reported a prominent seasonal distribution for campylobacteriosis (Spring), with C. ureolyticus (March) preceding C. jejuni/C.…”

“…An association with gastroenteritis has been shown for a broad range of species, including C. concisus [43], C. upsaliensis [44], C. fetus [45], C. ureolyticus [46], and C. hyointestinalis [47]. Lastovica and colleagues have shown that using non-selective culture, C. concisus and C. upsaliensis can be isolated with a frequency close to that of C. jejuni from diarrheal stools from children in South Africa, together representing 47% of all Campylobacter detections [48].…”

Purpose of review Recent work has added to the understanding of the burden of Campylobacter jejuni, C. coli, and non-jejuni/coli Campylobacter strains in children living in the developing world. Recent findings New diagnostic modalities and carefully-designed field studies are demonstrating that the burden of Campylobacter diarrhea in children in the developing world has been greatly underestimated. Furthermore, there is emerging recognition of an association between Campylobacter infection and malnutrition. Important progress has been made towards a Campylobacter jejuni vaccine. Finally, evidence of antibiotic resistance continues to be an important issue that is accentuated by the realization that the burden of disease is greater than previously recognized. Summary Additional research is needed to refine our understanding of the epidemiology of Campylobacter infections in developing countries, in particular to improve estimates of the burden of Campylobacter diarrhea in endemic settings, to determine the impact of recurrent Campylobacter infections on child development, and to describe the prevalence and clinical significance of non-jejuni/coli Campylobacter infections. Progressive antibiotic resistance of isolates argues for augmented and expanded control measures of antibiotics in livestock. Continued work in vaccine development is warranted as is the extension of data available on the serotypes related to burden in different areas of the world and the relationship of serotypes to disease severity.
