PRODUCTION OFA MONOCLONAL ANTIBODY<br />

AGAINST Tome SHOCK -ROME TOXIN-1<br />

Toxic shock syndrome ('ES) is a severe illness affecting<br />

mainly young menstruating females. It presents with a<br />

sudden onset of diverse symptoms and signs, including shock<br />

and multisystem involvement. The major causative agent of<br />

the disease is toxic shock syndrome toxin-l (TSST-l)<br />

produced by 30% of all clinical isolates of Stuphylococcus<br />

aureus.<br />

P<br />

The aim of this study was to roduce a monodonal antibody<br />

against TSST-1 and to app y the antibody in an enzyme<br />

linked immunosorbent assay (=SA) developed' for<br />

detection d the toxin.<br />

TSST-1 was purified from culture supematant by ethanol<br />

precipitation and ion exchange chromtoj$raphy. Balb/c<br />

mice were immmised with the toxin. AnQbody producing<br />

hybridomas were developed by fusing mouse spleen<br />

lymphocytes and Sp2/0 myelorna cells with addition of<br />

polyethylene glycol (PEG) to the cell suspe11sion. A<br />

standard EUSA technique was developed for screening of<br />

hybridoma cultures for anti-TSST-l antibo<strong>die</strong>s, and also for<br />

detection of TSST-1 production by clinical isolates of<br />

Swells<br />

A total of 1% clones developed from two fusion procedures.<br />

Ten of these clones were anti-TSST-l producers. One<br />

positive clone was selected for subclonin by limiting<br />

d<br />

dilution, resulting in five anti-TSST-l pr ucing clones.<br />

Forty persent of S. mrem clinical isolates examined in this<br />

study produced TSST-1.<br />

Although the diagnosis of.TSS is made mainly on the<br />

clinical evaluation of the patient, the use of a monoclonal<br />

antibody against the toxin my have diagnostic v ah~
