“in-house” production of dna size marker from a vaccinal bacillus anthracis strain

“In-house” production of DNA size marker from a vaccinal Bacillus anthracis strain

BACKGROUND AND OBJECTIVES DNA molecular weight marker is widely used in molecular biology experiments incurring considerable costs on low-budget settings. MATERIALS AND METHODS Here a PCR-supported procedure is described that uses 10 primer pairs targeting chromosomal DNA from the harmless vaccinal Bacillus anthracis Sterne 34F2 strain as template. A single PCR protocol is used to reproduce a...

Genome sequencing of two Bacillus anthracis strains: a virulent strain and a vaccinal strain

Bacillus anthracis strain SPV842_15 was isolated from bovine fetus, while B. anthracis strain Brazilian vaccinal was recovered from a commercial vaccine. We report here the genome sequences of both strains. The SPV842_15 genome is composed of a single circular chromosome with a length of 5,228,664 base pairs, and comprises 5911 coding sequences. In turn, the Brazilian vaccinal genome remains in...

Genome Sequence of Bacillus anthracis Strain Tangail-1 from Bangladesh

Soil was collected in July 2013 at a site where a cow infected with anthrax had been the month before. Selective culturing yielded Bacillus anthracis strain Tangail-1. Here, we report the draft genome sequence of this Bacillus anthracis isolate that belongs to the canonical A.Br.001/002 clade.

Construction of a Eukaryotic Plasmid Encoding Bacillus anthracis Protective Antigen, a Candidate for DNA Vaccine

Background: DNA immunization with plasmid DNA encoding bacterial, viral, parasitic and tumor antigens has been reported to trigger protective immunity. Objective: To evaluate the use of a DNA immunization strategy for protection against anthrax, a plasmid was constructed. Methods: The partialsequence of protective antigen of Bacillus anthracis, amino acids 175-764, as a potent immunogenic targe...

Stability and potency studies of anthrax vaccine (Bacillus anthracis 34F2 Sterne strain) in Iran

  For evaluation the stability and potency of anthrax vaccine prepared in Razi Vaccine and Serum Research Institute in Iran, samples of different batches of vaccine were kept at 4-8 °C (refrigerator), 20-25 °C (room temperature) and 37 °C (incubator).The viable spores/ml of vaccines were determined using plate–counting method before and after holding at different temperatures monthly. Vaccine p...
