The following report from the Iowa Veterinary Medical Diagnostic Lab oratory is a compilation of the animal disease material handled by the labor atory during the calendar year 1955. In previous years the report has been published in the Veterinary Division catalogue of Iowa State College and was probably seen by only a few of the veterinary practitioners of Iowa. With pub lication in the Iowa State College Veterinarian it will be available to very many more practitioners. It is hoped that the report will be of interest and helpful value to many of them. There are several limiting factors to keep in mind in drawing any con clusions from the report and it is more indicative of general trends than of relative importance of the various diseases found. It is a direct reflection of the interest in animal disease control and efforts on the part of practitioners to secure as much information of diagnostic value as possible. Excluding the serological tests for Brucellosis with both cattle and swine blood samples, the report covers the service requested in a total of 4,009 cases. Approximately 85 percent of these cases were submitted by veterinary practitioners. Such requests for service have been increasing each year during the past decade. In comparison with reports of previous years the 1955 report shows in creased interest in Brucellosis as evidenced by a larger number of tests; a marked increase in the number of animals tested for leptospirosis; many more cases of enterotoxemia in swine; a decrease in the apparent incidence of hog cholera; the first case of scrapie in Iowa sheep - but no cases of bluetongue

Iss'lLe 3, 1956 149 recorded; an upswing in the incidence of sahnonellosis in poultry; and the first report of ornithosis in poultry of Iowa. Since it is planned to continue publication of the annual report from the Diagnostic Laboratory in this journal, perhaps it would be informative to keep this issue for comparative purposes in future years.
