The aim of the study was to examine the hypothesis emitted by Evans et al. (2003) that mineral bottled water accidentally contaminated by Campylobacter jejuni would represent a risk factor for Campylobacter infection.Culturability of C. jejuni cells inoculated in low and high mineral bottled water during storage at 4°C in the dark was performed by surface plating and modelled using the Weibull model.The loss of C. jejuni culturability observed in all conditions tested was shown to be dependent from strain, preculture condition and water composition.Following inoculation of C. jejuni, the rapid loss of culturability was not correlated to complete cell death as the passage into embryonated eggs enabled recovery of cells from the Viable But Non Culturable state.In conclusion, the sanitary risk associated to contaminated bottled water can not be excluded although it is presumably low. Culture conditions, strain and water type must be taken into account in the evaluation of the risk factor as they influence significantly Campylobacter survival in water.

“…The bacterium itself is a largely zoonotic and does not usually reproduce in foods [4]. The host, in which it colonizes, ranges from wild birds to domestic animals [5,6]. In most cases, the bacterium multiplies in chicken and the animal become a reservoir of the pathogen [7].…”

Surface Plasmon Resonance Immunosensor for the Detection of Campylobacter jejuni

Abstract:Campylobacteriosis is an internationally important foodborne disease caused by Campylobacter jejuni. The bacterium is prevalent in chicken meat and it is estimated that as much as 90% of chicken meat on the market may be contaminated with the bacterium. The current gold standard for the detection of C. jejuni is the culturing method, which takes at least 48 h to confirm the presence of the bacterium. Hence, the aim of this work was to investigate the development of a Surface Plasmon Resonance (SPR) sensor platform for C. jejuni detection. Bacterial strains were cultivated in-house and used in the development of the sensor. SPR sensor chips were first functionalized with polyclonal antibodies raised against C. jejuni using covalent attachment. The gold chips were then applied for the direct detection of C. jejuni. The assay conditions were then optimized and the sensor used for C. jejuni detection, achieving a detection limit of 8 × 10 6 CFU·mL −1 . The sensitivity of the assay was further enhanced to 4 × 10 4 CFU·mL −1 through the deployment of a sandwich assay format using the same polyclonal antibody. The LOD obtained in the sandwich assay was higher than that achieved using commercial enzyme-linked immunosorbent assay (ELISA) (10 6 -10 7 CFU·mL −1 ). This indicate that the SPR-based sandwich sensor method has an excellent potential to replace ELISA tests for C. jejuni detection. Specificity studies performed with Gram-positive and Gram-negative bacteria, demonstrated the high specific of the sensor for C. jejuni.

“…In epidemiological studies, the commonly recognized risk factors for acquisition of campylobacter infection have been eating or handling poultry and drinking unpasteurized milk or untreated drinking water from private wells or groundwater sources (6,13,21). In waterborne epidemics associated with campylobacters, the drinking water source has been shown to be fecally contaminated either by runoff of surface water after rain or by leakage of a sewage pipe close to the drinking water pipeline (14,31).…”

“…Campylobacters colonize a wide variety of hosts, from domestic animals to wild birds (14,29), and thus the burden of campylobacters excreted via animal fecal material is extensive. Campylobacters are also common in natural water, such as streams, rivers, and lakes, due to discharges from wastewater treatment plants, runoff from pastures after rain, and direct contamination by wild birds (12).…”

Waterborne outbreaks associated with contamination of drinking water by Campylobacter jejuni are rather common in the Nordic countries Sweden, Norway, and Finland, where in sparsely populated districts groundwater is commonly used without disinfection. Campylobacters, Escherichia coli, or other coliforms have rarely been detected in potential sources. We studied three waterborne outbreaks in Finland caused by C. jejuni and used sample volumes of 4,000 to 20,000 ml for analysis of campylobacters and sample volumes of 1 to 5,000 ml for analysis of coliforms and E. coli, depending on the sampling site. Multiple samples obtained from possible sources (water distribution systems and environmental water sources) and the use of large sample volumes (several liters) increased the chance of detecting the pathogen C. jejuni in water. Filtration of a large volume (1,000 to 2,000 ml) also increased the rate of detection of coliforms and E. coli. To confirm the association between drinking water contamination and illness, a combination of Penner serotyping and pulsed-field gel electrophoresis (digestion with SmaI and KpnI) was found to be useful. This combination reliably verified similarity or dissimilarity of C. jejuni isolates from patient samples, from drinking water, and from other environmental sources, thus confirming the likely reservoir of an outbreak.
