Modelling Bacterial Dynamics in Food Products: Role of Environmental Noise and Interspecific Competition

Journal of Modern Physics 2013年第8期4卷 1059-1065页

In this paper we review some results obtained within the context of the predictive microbiology, which is a specific field of the population dynamics. In particular we discuss three models, which exploit tools of statistical mechanics, for bacterial dynamics in food of animal origin. In the first model, the random fluctuating behaviour, experimentally measured, of the temperature is considered. In the second model stochastic differential equations are introduced to take into account the influence of physical and chemical variables, such as temperature, pH and activity water, subject to deterministic and random variations. The third model, which is an extended version of the second one, neglects the environmental fluctuations, and concentrates on the role of the interspecific bacterial interactions. The comparison between expected results and observed data indicates that the presence of noise sources and interspecific bacterial interactions improves the predictive features of the models analyzed.

The progress of research in nucleic acid immunization promises new avenues to many infectious disease prophylaxis and therapeutics in human and animals. The commercialization and licensing of DNA vaccines are subjected to similar if not more stringent regulatory and market conditions as in many conventional vaccines in terms of administration regimen and dose presentation. The efficacy of a rabies DNA vaccine containing a plasmid encoding for the rabies virus glycoprotein gene was evaluated in dogs in a single-dose regimen. The extended duration of immunity of the vaccine was demonstrated by challenge with a wild type virus 17 months post vaccination. Similarly, conventional equine West Nile Virus vaccines are available in the United States as a monovalent as well as multivalent combination vaccines containing a number of other viral antigens.

人脑内去甲肾上腺素（NE）的主要代谢物为3-甲氧基4-羟基苯乙二醇（MHPG）,它与硫酸根结合后从小便中排出体外,故测定尿中MHPG-SO4可间接推测中枢NE活力的情况。文献中曾报道用硫酸酯酶水解或非酶水解方法分离出MHPG-SO4,后者与三氟醋酐作用,形成MHPG-三氟醋酸盐,再用GC-MS检测。这种检测方法灵敏度较大,但耗时多,又需精密昂贵的质谱仪,不适一般实验室用。本法用四丁基氯化铵（Tetrabutyl Ammonium Chloride）作为亲水性离子对,与尿中MHPG-SO4偶合,成四
