“…The outbreaks and sporadic cases of campylobacteriosis have frequently been reported that Campylobacter was isolated from patients. But it is often the case that the bacteria could not be isolated from suspected food or environmental samples [23,26,33,47]. There are many reasons for failure to identify the source of contamination, however it could be partly explained by the probable contamination of VBNC bacteria.…”

ABSTRACT. Campylobacter jejuni is the major cause of human gastroenteritis worldwide. Under stress conditions, C. jejuni can enter a viable but non-culturable (VBNC) state. We found that the C. jejuni was able to enter a VBNC state by prolonged incubation at 4C. The standard isolation methods using pre-enrichment steps in Bolton broth or Preston broth could not detect the VBNC cells in spiked chicken meat. The transcription levels of virulence-associated genes (flaA, flaB, cadF, ciaB, cdtA, cdtB and cdtC) were expressed in VBNC cells but in low levels. The VBNC cells retained the ability to invade Caco-2 human intestinal epithelial cells in vitro. In most cases, VBNC cells failed to resuscitate in Caco-2 cells, but in some experiments, they formed colonies after co-incubation with host cells. Collectively, C. jejuni enters into a VBNC state at 4C and the VBNC C. jejuni remains virulent which may possibly lead to disease in humans. C. jejuni in VBNC state is a potential concern for food safety.KEY WORDS: Campylobacter jejuni, resuscitation, viable but nonculturable state, virulence.

“…is usually associated with the consumption of contaminated food 22 . Nevertheless, a great number of outbreaks have been related to water, which has been considered an important transmission route 12 . Campylobacteriosis outbreaks have been associated mainly to chicken meat and their subproducts 9,19 .…”

SUMMARYThe genus Campylobacter is of great importance to public health because it includes several species that may cause diarrhea. These species may be found in water, food and in the intestinal tract of chickens. This study investigated the presence of Campylobacter jejuni and Campylobacter coli in chicken abattoirs in São Paulo State, Brazil. A total of 288 samples of feces, feathers, scald water, evisceration water, chiller water, and the rinse water of eviscerated, not eviscerated and chilled carcasses were collected in six chicken abattoirs. Polymerase Chain Reaction (PCR) was performed in Campylobacter spp.-positive isolates using the gene HIP, specific for hippuricase enzyme from Campylobacter jejuni and aspartokinase gene, specific to detect Campylobacter coli. The percentage of positive isolates of Campylobacter jejuni was 4.9% (14/288). Isolation was greater in feces samples (22%, 8/36). One sample was positive for the species C. coli. In conclusion, the results indicate that it is necessary to improve quality control for Campylobacter spp. in chicken abattoirs.

“…However, other enterohemorrhagic/Shiga toxin producing (STEC) strains of E. coli such as E. coli O157:H7 have caused well described drinking water outbreaks such as the Walkerton outbreak in Canada that was associated with more than 2000 cases and 7 deaths. Most drinking water associated outbreaks were associated with deficiencies in water treatment and/or disinfection especially in small water scale utilities and after heavy rainfall (Ackman et al, 1997;Bruneau et al, 2004;Friedman et al, 1999;Harrison and Kinra, 2004;Holme, 2003;Jones and Roworth, 1996;Olsen et al, 2002;Paunio et al, 1999;Wang et al, 2004). To the best of our knowledge, no outbreaks have been associated with well managed water systems.…”
