background: light chain (lc) and heavy chain carboxyterminal subdomain (hcc) fragments are the most important parts of tetanus neurotoxin (tent) which play key roles in toxicity and binding of tent, respectively. in the present study, these two fragments were cloned and expressed in a prokaryotic system and their identity was confirmed using anti-tent specific polyclonal and monoclonal antibodi...

results all 90 campylobacter isolates confirmed by m-pcr were successfully typed using flaa-pcr-rflp. eleven different types were defined according to flaa-typing method and the rflp patterns were located at three separate clusters in rflp image analysis dendrogram. conclusions campylobacter jejuni isolates significantly showed more variety than c. coli isolates. a relatively low genetic divers...

Fragment C is the C-terminal domain of the heavy chain of tetanus toxin that can promote the immune response against the lethal dose of this toxin. Therefore, this portion can be considered as a candidate vaccine against tetanus infection, which occurs by Clostridium tetani. The present study aimed to compare the expression of tetanus toxin fragment C in Escherichia coli  BL21 (DE3) pLysS cells...

Tetanus is a disease caused by tetanus toxin, a potent inhibitor for the release of inhibitory neurotransmitter in the central nervous system that causes spastic paralysis. Fragment C (52 kD) of this toxin is responsible for binding to the neuronal membrane. For this reason, and also its non toxigenic and immunogenic nature, this fragment might be ideal for new vaccine development. Presently, w...
