It has been established that environment facts determine the survival, growing and inactivation of the microorganisms. These risks are commonly associated with the presence of microbiological hazards and represent a serious problem from the Public Health viewpoint. The types of microorganisms presents in products will depend of the way they have been elaborated, transportated, stored, taking or prepared before eating. The guarantee of safety foods have impacted both to single and collective level: and also in economics. socials and sanitaries aspects. The sanitary microbiology like a science must be in context to the regional and national needs. with an important vinculation between different sectors of the society such as academy, industry and government, taking care of infrastructure and qualified personal, based on novel technology, actualized normative and making basical and applied research. The application of novel technology for the microbiological analysis of water and foods allows to show the microbial risk and also identify practices that compromise the safety of themself, with the final proposes of diminish or eliminate healthy risk due the food consumption.","PeriodicalId":21464,"journal":{"name":"Revista latinoamericana de microbiologia","volume":"48 2","pages":"226-30"},"PeriodicalIF":0.0,"publicationDate":"2006-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26785992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several reports show that bacteria, parasites and virus are involved in the burden of this disease. Most reports reveal Rotavirus A as the responsible etiological agent, at the same time, there seems to be some correlation between IAD and seasonal weather changes. To learn about the type of microbial agents associated with IAD in children during mildly changing yearly climatic conditions, as found in a high altitude tropical city, and to identify the viral agents affecting this population, stool samples from 300 children under 5 years of age were studied throughout a one-year period. Bacteria and intestinal parasites were identified by routine methods, while viruses were detected and typed by EIA and PCR. 20.6% of the IAD studied was associated with bacteria; 9% with parasites and 40% with virus. Group C Rotavirus accounted for 20.2%, group A Rotavirus for 13% and Calicivirus 10%. During November-April (p < 0.007) more virus associated IAD was found, while bacteria (p < 0.03) or parasite (p < 0.00014) related IAD was prevalent from May to October. The mild seasonal weather changes don't seem to be associated with any other microbial agent.","PeriodicalId":21464,"journal":{"name":"Revista latinoamericana de microbiologia","volume":"48 1","pages":"17-23"},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26602430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Only eight strains demonstrated inhibitory activity against spoilage microorganisms (i.e. Staphylococcus aureus and Bacillus cereus) and pathogens (i.e. E. coli, Salmonella sp. and Shigella sp.). Lactobacillus acidophilus AA11 produced a more antimicrobial activity with a wide range of inhibition. The agent AA11 was sensitive to proteolytic enzymes and retained full activity after 30 min at 100 degrees C. Activity against sensitive cells was bactericidal but not bacteriolytic. The compound was produced during growth phase and can be extracted from the culture supernatant fluids with n-Butanol. 12 % SDS-PAGE analysis of 40% ammonium sulphate precipitated agent showed two peptides with molecular weights of approximately 36 kDa and approximately 29 kDa. No plasmid was identified in Lactobacillus acidophilus AA11 indicating that the genes encoding the inhibitory agent located on the chromosome. These characteristics identify the inhibitory substance as a bacteriocin, designated acidocin AA11 and confer the agent an application potential as a biopreservative.","PeriodicalId":21464,"journal":{"name":"Revista latinoamericana de microbiologia","volume":"48 1","pages":"24-30"},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26602433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"[Co-evolutionary strategies of interaction between parasitoids and polydnaviruses].","authors":"Mario A Rodríguez-Pérez, Nancy E Beckage","doi":"","DOIUrl":"","url":null,"abstract":"Polydnaviruses are genetic symbionts of wasp endoparasitoids belonging to the hymenopteran families Ichneumonidae (ichnoviruses) and Braconidae (bracoviruses). They exist as proviruses integrated in the wasp's chromosomal genome, which then excise and undergo replication during the stage of adult development of the wasp. During wasp oviposition into their caterpillar host, the fully formed virus particles are injected along the parasitoid's eggs into the host hemocoel, where the eggs hatch and undergo larval development. The primary function of the polydnavirus is to trigger host immunosuppression so that host hemocytes are prevented from encapsulating the parasitoid's eggs and/or larvae. Polydnavirus transcripts are expressed following parasitization and alter host hemocyte adhesive properties that prevents encapsulation; in some species, viral gene expression triggers host hemocyte apoptosis, thereby rendering the host immunosuppressed. This review summarizes the major features of polydnaviruses and provides a global view of their functions in the lepidopteran hosts of the parasitoid wasps that carry them both as integrated viral sequences in their genome and as free virus to function physiologically in host regulation following parasitization of the host.","PeriodicalId":21464,"journal":{"name":"Revista latinoamericana de microbiologia","volume":"48 1","pages":"31-43"},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26602306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
