Abstract
The discovery of the microbe Shigella was dated back about I 00 years ago by a
scientist named Kiyoshi Shiga. Virulent Shigella spp. are known to cause bacillary
dysentery (shigeilosis) in humans which is characterized by the passage of bloody
stools. According to the WHO, an estimated of 1.1 million global population dies every
year is due to the disease shigellosis. Despite much studies were carried out regarding
this pathogenic bacteria, no vaccine is available for this infectious disease. Literatures
have postulated that one of the virulence genes is the apy gene which encodes for
apyrase.
Therefore, in this study the gene of interest is the apy gene. We have
successfully mutated the apy gene with a kanamycin gene cassette (aphA) and
subcloned the construct into a conjugative suicide vector.
