“…Birds, which have a high body temperature, appear to be an important reservoir of C. lari, which has been isolated from gulls (Glunder et al 1989), crows (Maruyama et al 1990) and chicken (Tresierra-Ayala et al 1994). Therefore, it is important to monitor these food products for contamination with campylobacters.…”

Campylobacters isolated from mussels and oysters in The Netherlands were analysed by a novel assay, based on DNA amplification with primers, based on semiconserved GTP‐binding sites of a putative GTPase gene. Polymerase chain reaction (PCR) was followed by a single step reverse hybridization line probe assay (PCR‐LiPA). This permits identification of Campylobacter jejuni, C. coli, C. lari and C. upsaliensis. Among a group of 44 isolates, three C. jejuni, one C. upsaliensis, one double infection with C. jejuni and C. coli, and 38 C. lari strains were identified. These results were in complete agreement with conventional identification methods and whole cell protein analysis. One C. hyointestinalis isolate was not identified by the PCR‐LiPA, since the reverse hybridization assay does not comprise specific probes for this particular species. PCR products from 36 C. lari isolates were sequenced and phylogenetic analysis revealed the presence of two major C. lari subgroups: one comprised 11 highly homologous sequences, whereas the 25 sequences in the other subgroup were more heterogeneous. This confirmed earlier findings that C. lari isolates comprise a more heterogeneous group of isolates as compared with C. jejuni, C. coli and C. upsaliensis. Based on the sequence information, a novel PCR‐LiPA was developed that permits specific and rapid detection of the different C. lari variants.

“…In addition to chickens, commercial turkeys and ducks can also serve as reservoirs of C. jejuni and C. coli (315)(316)(317). Furthermore, poultry is also an important reservoir of other Campylobacter species, such as C. lari, C. upsaliensis, and C. concisus (318,319). Domesticated broiler chickens and imported chickens both contribute to the overall burden of Campylobacter infections (320).…”

Global Epidemiology of Campylobacter Infection

SUMMARY Campylobacter jejuni infection is one of the most widespread infectious diseases of the last century. The incidence and prevalence of campylobacteriosis have increased in both developed and developing countries over the last 10 years. The dramatic increase in North America, Europe, and Australia is alarming, and data from parts of Africa, Asia, and the Middle East indicate that campylobacteriosis is endemic in these areas, especially in children. In addition to C. jejuni , there is increasing recognition of the clinical importance of emerging Campylobacter species, including Campylobacter concisus and Campylobacter ureolyticus . Poultry is a major reservoir and source of transmission of campylobacteriosis to humans. Other risk factors include consumption of animal products and water, contact with animals, and international travel. Strategic implementation of multifaceted biocontrol measures to reduce the transmission of this group of pathogens is paramount for public health. Overall, campylobacteriosis is still one of the most important infectious diseases that is likely to challenge global health in the years to come. This review provides a comprehensive overview of the global epidemiology, transmission, and clinical relevance of Campylobacter infection.

“…The C. lari group strains are also isolated from marine mammals ( C. insulaenigrae , C. lari [ Foster et al 2004 ; Stoddard et al 2007 ; Garcia-Pena et al 2010 ; Gonzalez et al 2011 ]), shellfish ( C. lari , C. peloridis [ Endtz et al 1997 ; Van Doorn et al 1998 ; Debruyne et al 2009 ]), and seawater/fresh water ( C. lari , UPTC [ Obiri-Danso and Jones 1999 ; Obiri-Danso et al 2001 ; Meinersmann et al 2013 ; Khan et al 2014 ]). Even though members of the C. lari group have been isolated from livestock ( Tresierra-Ayala et al 1994 ; Aarestrup et al 1997 ; Harvey et al 1999 ; Scanlon et al 2013 ), this clade is primarily associated with coastal regions and watersheds.…”

The Campylobacter lari group is a phylogenetic clade within the epsilon subdivision of the Proteobacteria and is part of the thermotolerant Campylobacter spp., a division within the genus that includes the human pathogen Campylobacter jejuni. The C. lari group is currently composed of five species (C. lari, Campylobacter insulaenigrae, Campylobacter volucris, Campylobacter subantarcticus, and Campylobacter peloridis), as well as a group of strains termed the urease-positive thermophilic Campylobacter (UPTC) and other C. lari-like strains. Here we present the complete genome sequences of 11 C. lari group strains, including the five C. lari group species, four UPTC strains, and a lari-like strain isolated in this study. The genome of C. lari subsp. lari strain RM2100 was described previously. Analysis of the C. lari group genomes indicates that this group is highly related at the genome level. Furthermore, these genomes are strongly syntenic with minor rearrangements occurring only in 4 of the 12 genomes studied. The C. lari group can be bifurcated, based on the flagella and flagellar modification genes. Genomic analysis of the UPTC strains indicated that these organisms are variable but highly similar, closely related to but distinct from C. lari. Additionally, the C. lari group contains multiple genes encoding hemagglutination domain proteins, which are either contingency genes or linked to conserved contingency genes. Many of the features identified in strain RM2100, such as major deficiencies in amino acid biosynthesis and energy metabolism, are conserved across all 12 genomes, suggesting that these common features may play a role in the association of the C. lari group with coastal environments and watersheds.
