Specific detection of Arcobacter spp. in estuarine waters of Southern Italy by PCR and fluorescent in situ hybridizationEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: Culturable and nonculturable forms of Arcobacter in the estuarine environment were present. PCR assays were more sensitive than traditional culture in detecting Arcobacter butzleri and A. cryaerophilus. FISH comparatively to PCR technique may provide information about cell morphology and viability of single cells.Significance and Impact of the Study: Our investigation indicates the existence of an environmental reservoir of potential pathogenic arcobacters in an estuarine Italian area, which may survive under a viable but not culturable state.

The insight implies that instead of viability improvement of dried cells by the conventional stress induction during cultivation, the induction may be exercised thereafter without compromising growth of the cells.

Comparison of in vitro models to study bacterial adhesion to the intestinal epitheliumEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: The results suggested that bacterial strains exhibit different capacities to adhere to cellular components and several types of mucin present in different models, showing preferences for intestinal MUC2.Significance and impact of the study: The use of Caco-2 cells monolayer plus mucin (type II) better approaches the physiological characteristics of in vivo situation, providing a reliable and suitable in vitro model to evaluate bacterial adhesion.

Identification of coliform genera recovered from water using different technologiesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: A wide range of coliform genera were detected using both types of methods. There was considerable overlap between the two groups, and whilst differences were seen between the genera isolated with the two method types, no clear pattern emerged. Substantial numbers of 'new' coliforms (e.g. Raoutella spp.) were recovered using both types of methods.Significance and Impact of the Study: The results presented here confirm that both methods based on lactose fermentation or detection of [beta]-d-galactosidase activity recover a range of coliform organisms. Any suggestion that only methods which are based upon ferment...

Effect of production conditions on the stability of a human bifidobacterial species Bifidobacterium longum in yogurtEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: In this investigation, the human bifidobacterial strain Bif. longum survived adequately in yogurt, although the fermentation temperature and starter composition affect bifidobacterial survival.Significance and Impact of the Study: This investigation indicates that stable probiotic yogurt using human bifidobacteria can be produced by choosing optimal production conditions.

Isolation and characterization of an atrazine-degrading Rhodococcus sp. strain MB-P1 from contaminated soilEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: We have successfully isolated a Rhodococcus sp. strain MB-P1 which is capable of utilizing atrazine as sole source of carbon and energy at very high concentrations of 1000 ppm. The pathway for degradation of atrazine has also been determined. The metabolic gene(s) responsible for atrazine degradation was found to be plasmid-encoded.Significance and Impact of the Study: Rhodococcus sp. strain MB-P1 could be used as an ideal model system for in-situ degradation and restoration of ecological niches which are heavily contaminated with atrazine.

Bacterial contamination on touch surfaces in the public transport system and in public areas of a hospital in LondonEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: Hand-touch sites in London are frequently contaminated with bacteria and can harbour MSSA, but none of the sites tested were contaminated with MRSA.Significance and Impact of the Study: Hand-touch sites can become contaminated with staphylococci and may be fomites for the transmission of bacteria between humans. Such sites could provide a reservoir for community-associated MRSA (CA-MRSA) in high prevalence areas but were not present in London, a geographical area with a low incidence of CA-MRSA.

Production of tylosin in solid-state fermentation by Streptomyces fradiae NRRL-2702 and its gamma-irradiated mutant (γ-1)Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: The study has shown that solid-state fermentation system significantly enhanced the tylosin yield by mutant [gamma]-1.Significance and Impact of the Study: This study proved to be very useful and resulted in 6·87 ± 0·30-fold increase in tylosin yield by this mutant when compared to that of wild-type strain.

Effects of moderately high pressure plus heat on the germination and inactivation of Bacillus cereus spores lacking proteins involved in germinationEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: Both inactivation and germination of B. cereus spores by MHP increased with rise of temperature; however, mutant strains lacking individual germinant receptor had similar levels of germination as compared to wild-type spores. To evaluate the role of germinant receptors in MHP, a strain lacking a large number of germinant receptors is needed.Significance and Impact of the Study: The results of this work may lead to a better understanding of how MHP causes germination of spores of B. cereus.

Epitope mapping of pathogenic Leptospira LipL32Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: Epitope identification and analysis suggested the existence of two antigenic regions within LipL32. These LipL32 reactive regions were highly conserved among antigenically variants of Leptospira spp. isolates. Peptides containing these regions (P1 and P2) showed a good capability for anti-leptospiral antibody recognition.Significance and Impact of the Study: This finding could have potential relevance not only for serodiagnosis but also as a starting point for the characterization of targets for vaccine design.
