“…Rollins and Colwell (1986) did provide some preliminary evidence suggesting that the reversion from coccoid to spiral forms occurred following animal passage. Nonculturable forms of Campylobacter spp., observed in water supplies by direct immunofluorescence microscopy, were able to give rise to colonization of chickens following consumption of this water (Pearson et al 1993), supporting the existence of a resuscitative VBNC form. Further investigations showing the resuscitation of putative VBNC cells in laboratory animals (Jones et al 1991;Saha et al 1991;Stern et al 1994;Tholozan et al 1999), aquatic environments (Thomas et al 2002) and after acid treatment (Chaveerach et al 2003) have been reported.…”

Environmental survival mechanisms of the foodborne pathogen Campylobacter jejuni

Campylobacter spp. continue to be the greatest cause of bacterial gastrointestinal infections in humans worldwide. They encounter many stresses in the host intestinal tract, on foods and in the environment. However, in common with other enteric bacteria, they have developed survival mechanisms to overcome these stresses. Many of the survival mechanisms used by Campylobacter spp. differ from those used by other bacteria, such as Escherichia coli and Salmonella spp. This review summarizes the mechanisms by which Campylobacter spp. adapt to stress conditions and thereby increase their ability to survive on food and in the environment.

“…Studies in many countries have shown that drinking water can be a direct source of human infection (Abe et al, 2008;Uhlmann et al, 2009;Karagiannis et al, 2010;Gubbels et al, 2012). Perhaps, more importantly, the environment is also an important source for the primary and secondary colonisation of food animals, particularly chickens (Pearson et al, 1993;Ogden et al, 2007;Perez-Boto et al, 2010). It is likely that routes of transmission flowing through the environment, farm animals and wild animals through to humans interact in complex ways (Fig.…”

“…It has been reported that C. jejuni can respond to unfavourable conditions, including low nutrient environments, by entering a VBNC state (Rollins & Colwell, 1986;Pearson et al, 1993;Murphy et al, 2006) and that oxygen can accelerate this transition to VBNC (Klancnik et al, 2006). In the VBNC state, bacteria lose the ability to form colonies on normal growth media and reduce their metabolic activity but retain viability and the potential to recover, and even cause infections (Barer & Harwood, 1999).…”

Campylobacter species are the most common cause of bacterial gastroenteritis, with C. jejuni responsible for the majority of these cases. Although it is clear that livestock, and particularly poultry, are the most common source, it is likely that the natural environment (soil and water) plays a key role in transmission, either directly to humans or indirectly via farm animals. It has been shown using multilocus sequence typing that some clonal complexes (such as ST-45) are more frequently isolated from environmental sources such as water, suggesting that strains vary in their ability to survive in the environment. Although C. jejuni are fastidious microaerophiles generally unable to grow in atmospheric levels of oxygen, C. jejuni can adapt to survival in the environment, exhibiting aerotolerance and starvation survival. Biofilm formation, the viable but nonculturable state, and interactions with other microorganisms can all contribute to survival outside the host. By exploiting high-throughput technologies such as genome sequencing and RNA Seq, we are well placed to decipher the mechanisms underlying the variations in survival between strains in environments such as soil and water and to better understand the role of environmental persistence in the transmission of C. jejuni directly or indirectly to humans.

“…Waterborne outbreaks of Campylobacter occur occasionally and are normally associated with faecal contamination of the water source from agricultural waste run-off, bird droppings or sewage outflow (Bobb et al 2003;Clark et al 2003;Hanninen et al 2003). Contaminated groundwater may serve as a source of inoculation of drinking waters with C. jejuni or the introduction of the organism into livestock populations where groundwater is used as a source of drinking and irrigation (Pearson et al 1993;Stanley et al 1998;Hanninen et al 2003). The survival of C. jejuni in groundwater is not surprising as the environmental conditions (e.g.…”

Aims: To evaluate the survival of Campylobacter jejuni relative to that of Escherichia coli in groundwater microcosms varying in nutrient composition. Methods and Results: Studies were conducted in groundwater and deionized water incubated for up to 470 days at 4°C. Samples were taken for culturable and total cell counts, nutrient and molecular analysis. Die‐off in groundwater microcosms was between 2·5 and 13 times faster for C. jejuni than for E. coli. Campylobacter jejuni had the lowest decay rate and longest culturability in microcosms with higher dissolved organic carbon (4 mg l−1). Escherichia coli survival was the greatest when the total dissolved nitrogen (12·0 mg l−1) was high. The transition of C. jejuni to the coccoid stage was independent of culturability. Conclusion: The differences in the duration of survival and response to water nutrient composition between the two organisms suggest that E. coli may be present in the waters much longer and respond to water composition much differently than C. jejuni. Significance and Impact of the Study: The data from these studies would aid in the evaluation of the utility of E. coli as an indicator of C. jejuni. This study also provided new information about the effect of nutrient composition on C. jejuni viability.
