Description:
S. iniae is an important pathogen in both marin animals and humans, causing systemic infections in these hosts. The symptoms of infections are very similar to symptoms of infections caused by human¬specific streptococcal pathogens. The enzyme phosphoglucomutase (PGM) has recently been discovered to play an important role in polysaccharide capsule production and virulence in s. iniae. We aim to isolate S. iniae and cloning phosphoglucomutase gene. S. iniae grew on sheep blood agar as mucoid and beta- hemolytic colonies after 24 h of incubation at 37C. Then confirmed it by sensitive and rapid method of PCR. The pgm gene was amplified successfully and cloned in pTZ57R cloning vector.The recombinant plasmid was sub cloned into pETDuet-l expression vector by rectriction enzymes and confirmed by PCR . Although S. iniae is a pathogen of economic importance, relatively little is known regarding mechanisms of its pathogenesis and few specific virulence determinants have been established. These include the enzyme phosphoglucomutase which contributes to cell wall integrity and resistance to antimicrobial peptides. Thus, this enzyme is the best choice to product the vaccine and more investigations.
