Evaluation of Chitosan Nanoparticle Antimicrobial Effect on Isolated Bacteria from Pregnant Women and ATCC 7644.

Background: is a gram positive, facultative intracellular bacteria and it is a causative agent of . Abortion is one the most important side effect of . Nano chitosan is widely used as nanomaterials considered due to its characteristics such as bactericidal and nontoxicity activity.

Investigating the Efficiency of Recombinant FliC-Loaded Spores in Mice Immunization against Serovar Typhi.

Background: Bacterial spores are among the most efficient vaccine delivery vehicles. Because of their safety and efficacy, spores are increasingly used in this regard. The negatively charged surfaces of the spores allow antigens to be adsorbed onto these structures.

Two new rapid PCR-based methods for identification of Acinetobacter baumannii isolated from clinical samples.

The accurate identification of Acinetobacter spp. is challenging due to their high phenotypic and biochemical similarities. Because clinical relevance and antibiotic susceptibility are significantly different among different genomic species of Acinetobacter, the exact identification of A.

Design, Expression and Purification of IgG4 Immunoreactive Protein (NIE) in .

Background: Strongyloidiasis is a public health concern in northern regions of Iran, caused by . Auto-infection cycle can be resulted in high parasitic load, especially in immunocompromised hosts. Because of low sensitivity of stool culture and stool-based microscopy techniques, detection of antibodies in patient's sera can be an alternative diagnostic technique for detection of the nematode.

Effect of Chitosan Nanoparticle from Shrimp on and .

Background: After cellulose, chitin is one of the most important polymers in crustaceans, insects, and fungi. Chitosan is one of the most important derivatives of chitin, which has important characteristics including degradability, non-toxicity, and biocompatibility antimicrobial and antioxidant properties.

Methods: Chitosan was extracted from shrimp using chemical methods and the degree of its austenitization was determined using a sub-red spectrophotometer and XRD.
