Immunological characterization of the chemically prepared ghosts of Salmonella Typhimurium as a vaccine candidate.

Background: Bacterial ghosts are the evacuated bacterial cellular membranes from most of the genetic and protein contents which preserved their surface characters. Recently, bacterial ghosts exploited for different biomedical applications, for instance, vaccination. The purpose of this study is to measure the immunogenic protective response of bacterial ghosts of Salmonella Typhimurium in animals and to allow future testing this response in humans.

Salmonella-innovative targeting carrier: Loading with doxorubicin for cancer treatment.

Cell- based targeted delivery is recently gain attention as a promising platform for delivery of anticancer drug in selective and efficient manner. As a new biotechnology platform, bacterial ghosts (BGs) have novel biomedical application as targeted drug delivery system (TDDS). In the current work, Salmonellas' BGs was utilized for the first time as hepatocellular cancer (HCC) targeted delivery system.

A novel protocol for bacterial ghosts' preparation using tween 80.

Bacterial ghosts (BGs) can be prepared by both genetic and chemical means. Genetic method include using lysis gene . Chemical method include incubation with numerous agents for a short time at their minimum inhibitory or minimum growth concentrations (MIC or MGC).

Expression and purification of hepatitis B surface antigen S from Escherichia coli; a new simple method.

Background: Hepatitis B is a liver disease primarily caused by hepatitis B virus (HBV) infection. It is distributed worldwide and associated with high mortality and morbidity rates. HBV infections can be avoided by the administration of the currently available vaccine and can be easily diagnosed through commercially available kits.
