ITEM 2.   ACQUISITION OR DISPOSITION OF ASSETS
          ------------------------------------

On July 9, 1997 the Company acquired the worldwide veterinary diagnostic
business of Rhone Merieux S.A. pursuant to purchase agreements dated May 14,
1997.  The consideration paid to Rhone Merieux was $10,659,000 in cash and plus
759,000 shares of newly issued, unregistered Synbiotics common stock valued at
$3,178,000 (based upon the closing price of Synbiotics' Common Stock on July 9,
1997 which was $4.1875 per share).  The shares issued by the Company include
230,000 shares which have been placed in escrow pending certain U.S. regulatory
approvals and subsequent sales of related products. The 759,000 shares will be
subject to certain registration rights as well as put and call provisions.
Depending on performance of the combined business in the three years following
the acquisition, Synbiotics may also pay up to $3,600,000 in contingent cash
payments.  The cash portion of the consideration was provided by a series of
loans obtained from Banque Paribas.

Rhone Merieux and Synbiotics also entered into related agreements covering the
supply of various products and services, collaborative research and development,
licenses of Rhone Merieux patents, and the distribution of certain of the
acquired products by Rhone Merieux.  The collaborative research agreement gives
Synbiotics a right of first refusal to acquire technology or products emanating
from Rhone Merieux's future research efforts that have potential veterinary
diagnostic applications.

In addition, the Company acquired Rhone Merieux's veterinary diagnostic
research, manufacturing and European laboratory marketing organization based in
Lyon, France.  All of the assets acquired by Synbiotics were used and will
continue to be used to operate the veterinary diagnostic business activities
described above.
