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~
