An investigation of the prevalence of Campylobacter ureolyticus in a variety of animals led to the identification of the strain CIT 045 T , in the faeces of captive lion-tailed macaques (Macaca silenus). Originally, believed to be Campylobacter ureolyticus based on the colony morphology and positive urease test, analysis of 16S rRNA and hsp60 gene sequences of this isolate revealed that the strain differs significantly from other species of the genus Campylobacter described to date. Species-specific primers for 16S rRNA and hsp60 genes were designed and used to identify two additional strains isolated from faeces samples from other macaques. Nucleotide sequence analysis of the 16S rRNA and hsp60 genes revealed ¡95 % and ¡82 % sequence similarity to recognized species of the genus Campylobacter respectively. All three isolates formed a distinct group within the genus Campylobacter based on their 16S rRNA and hsp60 sequences and matrix-assisted laser desorption/ionization time of flight (MALDI-TOF) profiles. The unique species status was further supported by phenotypic characteristics of the isolates. All isolates were found to be oxidase-, catalase-and urease-positive, they grew well at 37 6C and 42 6C and produced H 2 S on TSI (triple-sugar iron) and SIM (sulfide indole motility) media. The name Campylobacter corcagiensis sp. nov. is proposed for this novel species, with the strain CIT 045 T as the type strain CIT 045 T (5LMG 27932 T , CCUG 64942 T ).The genus Campylobacter has expanded considerably since it was initially proposed by Sebald & Veron (1963), at the time of writing encompassing 24 species and eight subspecies (On, 2013). Species of the genus Campylobacter inhabit a wide variety of ecological niches and have been isolated from various sample sources and hosts; including humans, birds, livestock, pets and primates (Man, 2011). Furthermore, several of these species have been associated with diseases in humans and animals.Interestingly, even though some species of the genus Campylobacter, such as Campylobacter jejuni, have been isolated from a variety of hosts, including wild birds, domestic animals and humans, multilocus sequence typing analysis has revealed a wide genetic strain diversity of C. jejuni among different hosts (Griekspoor et al., 2013). Furthermore, some strains have been found to be hostspecific, being confined to a particular wild bird species (rather than geographical location). Other genetic populations have been found to be more widely distributed between different species and have been found to be present in humans and livestock (Griekspoor et al., 2013). This heterogeneity highlights the possibility of transspecies transmission and the zoonotic potential of many species of the genus Campylobacter.As a part of a larger study investigating possible environmental sources of Campylobacter ureolyticus, faecal samples were collected from captive wild animals. Samples were collected using sterile swabs which were immediately placed in a sterile 25 ml container filled with Bolton Broth (O...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
