This study aimed to evaluate the efficiency of stretching in the reduction of pathogens when compared to milk pasteurization, the official method to ensure safe cheese production. Whole buffalo milk was contaminated with Mycobacterium fortuitum, Listeria monocytogenes, Salmonella typhimurium, and Staphylococcus aureus. Part of the milk was used in mozzarella production and the other part was submitted to holder pasteurization. Pathogens were quantified before and after thermal processing (mozzarella stretching and milk pasteurization). Pasteurization and stretching led to the following reductions in log cycles, respectively: 4.0 and 6.3 for Mycobacterium sp.; 6.0 and 8.4 for Listeria sp.; >6.8 and 4.5 for Staphylococcus sp.; and >8.2 and 7.5 for... |

The present paper evaluated the microbiology of salmon by quantifying mesophilic heterotrophic microorganisms, total and thermotolerant coliforms, and the presence of Vibrio parahaemolyticus, Staphylococcus aureus, Salmonella sp., Escherichia coli and Aeromonas sp. in the meat. This study can provide technical support for the suggestion of a new regulation of a Brazilian legislation through specific microbiological standards concerning the consumption of raw fish. A number of 31 (16 cooled and 15 frozen) samples of salmon were collected in the retail market network of a few cities in the State of São Paulo, Brazil. Results presented populations of mesophilic heterotrophic microorganisms ranging from 1.0 x 10 and 3.9 x 10(6) CFU/g, total and thermotolerant... |

Seagrasses species in Bardawil Lake have been defined through broad quantitative sampling. From the biochemical constituent's point of view, two species namely; Cymodocea nodosa and Ruppia cirrhosa were evaluated as feed additives and antimicrobial active compounds. The obtained results showed an obvious increase in chlorophyll "a", carbohydrate and lipid contents in the C. nodosa than R. cirrhosa while protein contents was higher in R. cirrhosa than in C. nodosa. Whole plant tissues powder substance (10.0%w/v) and ethanolic extracts (200μg/ml) of C. nodosa and R. cirrhosa were evaluated against some microorganisms using pour plate technique. Powdered substance of C. nodosa was exhibited the highest antifungal activity than that of R. cirrhosa, also its... |

Cette étude a porté sur la recherche des bactéries appartenant au genre Listeria (Listeria spp.) dans 61 échantillons de coquillages issus de quelques zones de production situées dans le département du Finistère. Ces investigations, effectuées au cours de deux périodes (janvier-février et juillet -août 1994), ont mis en évidence la présence régulière des Listeria dans les bivalves (L. spp.= 49.2% ), la part non négligeable de Listeria monocytogenes (L.m. = 11.5%), la multiplicité d'espèces sur quelques échantillons testés (Baie de Morlaix) ainsi qu'une large distribution de ce genre bactérien. Par ailleurs, il est démontré une incidence saisonnière,la période hivernale se révélant la plus critique. Cette information, intéressante sur le plan sanitaire,... |

L’algue brune Padina pavonica a été récoltée durant une période d’une année (Juillet 2006 à Juin 2007), dans la côte nord de la Tunisie (Cap Zebib) en vue d'évaluer l'activité antibactérienne d’extraits bruts de l’algue et leur variabilité saisonnière. Les extraits d’algue ont été préparés en utilisant le Dichlorométhane et le Dichlorométhane/Méthanol et testés périodiquement (tous les mois) sur une gamme de bactéries pathogènes et des bactéries associées isolées de l’algue. Une variation significative de l'activité antibactérienne liée au solvant d’extraction utilisé a été notée. Ainsi, les extraits au Dichloromethane/Méthanol sont plus actifs. Aussi nous avons noté la présence d’une variabilité saisonnière de l'activité antibactérienne. Ce sont les... |

The paper deals with the hygienic advantages of sanitation to treat dairy manure in full-scale biogas plants. Slurry samples were collected from two thermophilic biogas plants (55ºC) and two mesophilic biogas plants (38ºC) in Hokkaido, Japan. The detectable number of Coli-aerogenes group and Enterococcus in the slurries after anaerobic digestion could not be found in both thermophilic biogas plants. In both mesophilic biogas plants, however, the viable numbers of Coli-aerogenes group and Enterococcus were detected in the slurries even after anaerobic digestion. The mean decimation reduction time (T90) values of Coli-aerogenes group and Enterococcus in the slurries during mesophilic digestion were 13.3 d and 16.7 d, respectively. |
