T he rapid growth of the World Wide Web and advances in networking technology have made it more important than ever to secure personal computers and operating systems. Individual users as well as enterprises need to know that the systems they are using will not divulge personal or copyrighted information to hackers or accept viruses, worms, Trojan horses, or unsolicited e-mail that can slow or ...

To the Editor: The etiologic agent of the sixth pandemic of cholera was classical biotype of Vibrio cholerae O1. The ongoing seventh pandemic is caused by El Tor biotype. The biotypes are differentiated by phenotypic and genotypic characteristics. However, this differentiation blurred when V. cholerae O1 strains were detected in Matlab, Bangladesh, in 2006, in which characteristics were mixed. ...

The aim of the work was a comparative study expression main virulence genes in Vibrio cholerae strains classical biovar, typical and genetically modified V. , El Tor biovar. Materials methods . Natural toxigenic O1, biovar (J89, Pakistan, 1969), (M-887, Astrakhan, 1970) (301, Taganrog, 2011) were used as model ones. grown under optimum conditions for production cholera toxin toxin-coregulated p...

Enumerates and compares a number of security-enabling architectures for network clients. These architectures, either proposed as methodologies or currently implemented in software and/or hardware, are capable of protecting the client’s software integrity and its environment. The most important methodologies include the reference monitor model, firewalls, and virtual machines. Software implement...

In this study, a total of 54 Vibrio alginolyticus strains were analyzed. The isolates were recovered from different compartments of the Ruditapes decussatus hatchery in the National Institute of Marine Sciences and Technologies, Monastir, Tunisia. All isolates were biochemically identified (API 20E and API ZYM strips), characterized by amplification of the Hsp-40 gene polymerase chain reaction ...
