Escherichia coli O26 IN RAW BUFFALO MILK: PRELIMINARY RESULTS

Escherichia coli O26 is considered to be one of the most important food-borne pathogen. In this study, 120 buffalo milk samples collected in Lazio and in Apulia regions were tested for the presence of E. coli O26. One buffalo milk sample (0,8%) tested positive for E. coli O26; the isolate was positive at the verocytotoxicity test and it showed resistance properties to different antimicrobial classes. These preliminary results highlight the need to monitor the foods of animal origin used for production and eaten by a wide range of persons, respect VTEC organism

Statistical Multifragmentation in Central Au+Au Collisions at 35 MeV/u

Multifragment disintegrations, measured for central Au + Au collisions at E/A = 35 MeV, are analyzed with the Statistical Multifragmentation Model. Charge distributions, mean fragment energies, and two-fragment correlation functions are well reproduced by the statistical breakup of a large, diluted and thermalized system slightly above the multifragmentation threshold.Comment: Latex file, 8 pages + 4 postscript figures available upon request from [email protected]

Multifragment production in Au+Au at 35 MeV/u

Multifragment disintegration has been measured with a high efficiency detection system for the reaction $Au + Au$ at $E/A = 35\ MeV$. From the event shape analysis and the comparison with the predictions of a many-body trajectories calculation the data, for central collisions, are compatible with a fast emission from a unique fragment source.Comment: 9 pages, LaTex file, 4 postscript figures available upon request from [email protected]. - to appear in Phys.

Rapid Method for Detection of Anisakidae Larvae in Marine Fishes, Based on UV Transillumination

A rapid and sensitive detection method is proposed to evaluate the presence and vitality degree of Anisakidae larvae in marine fishes by UV diaphanoscopy. 923 fish samples belonging to seven fish species (Merluccius merluccius, Molva elongata, Sardina pilchardus, Scomber scomber, Triglia lucerna, Engraulis encrasicolus, and Trachurus trachurus) were evaluated for the presence of Anisakidae larvae by using direct observation, peptic digestion, and UV transillumination. The results obtained indicate that UV transillumination can be considered a rapid and accurate tool for routine analysis of marine fishes even under field condition
