Desiccation resistance in Arcobacter butzleri

Abstract

The desiccation resistance of A. butzleri was studied. Two, 3 and 4 of the strains did not resist desiccation for more than 2, 12 and 36 h, respectively. Two strains resisted desiccation for > 48 h. A. butzleri seems to be more resistant to desiccation than the classical enteropathogenic Campylobacter species.

Persistence of Arcobacter butzleri CCUG 30484 on plastic, stainless steel and glass surfaces

“…To our best knowledge, there is a small contribution concerning desiccation tolerance of A. butzleri strains isolated from commercial chicken liver (11). Authors found that arcobacter strains did not resist desiccation in the range from 2 to 36 h. In our study, A. butzleri strain was able to survive from 1·0 to 5·5 h in condition of low relative humidity (32% RH) regardless of surface material or suspending medium used.…”

“…They are highly susceptible to desiccation and do not survive well on dry surfaces (3,4,6,14). Despite of the phylogenetic similarities observed between Arcobacter and Campylobacter, A. butzleri seemed to be more resistant to desiccation than the classical enteropthogenic Campylobacter species (11).…”

Survival and Inactivation ofArcobacterspp., a Current Status and Future Prospect

“…to various environmental and food-related stress factors have undoubtedly had a significant scientific impact, there is one important factor that severely limits our ability to generalize from the published results. Almost all the studies cited were conducted with a single strain with the exception of research examined in desiccation tolerance of A. butzleri (11 strains) (Otth et al 2001), the effect of pH, NaCl content and temperature on the growth of A. butzleri and A. cryaerophilus (4 and 2 strains, respectively) (D'Sa and Harrison 2005), antimicrobial effect of siderophores (2 isolates) (Peškova et al 2006), and heavy metals (50 strains) (Otth et al 2005) on the growth and survival of Arcobacter spp. From the reports discussed above, we can claim that most Arcobacter strains are not very susceptible to desiccation and can tolerate higher sodium chloride concentration in the media than reported for Campylobacter spp.…”

“…Our recent initial study (not published yet) revealed that A. butzleri cells (one single strain) were able to survive on plastic, glass o stainless steel coupons for a considerable period of time (for up to 5.5 h) and even after the droplet of suspending medium has been visibly dried. Therefore, the ability of A. butzleri (strain ATCC 49616) to attach to various surfaces (plastic or stainless steel) (Assanta et al 2002) together with its enhanced desiccation tolerance (Otth et al 2001) may indicate the potential for crosscontamination in food handling practices as a serious problem. It has to be noted that the desiccation tolerance of A. butzleri was strain depended, although all the strains tested were isolated from the similar food products (commercial chicken livers) as was reported by Otth and her co-workers (2001).…”

The survival of Arcobacter butzleri, an emerging human pathogen, in the presence of acids or ethanol

“…It cannot be assumed that because C. jejuni, the related organism is susceptible to various cleaning regimes/treatments that A. butzleri will be similarly affected. The two species are affected differently by radiation (Collins et al, 1996), by desiccation (Otth et al, 2001) and by antimicrobial agents (Corry and Atabay, 1997;.…”
