caprine pleuropneumonias and contagious agal- 

 actia are caused by mycoplasmas and East Coast 

 fever by a blood parasite (hematozoan). Some of 

 the diseases affect wild animals and birds in 

 addition to domestic animals. About 70 percent 

 of the research and service work is devoted to 

 foot-and-mouth disease because of its great 

 economic importance. Techniques and materials 

 are being developed for rapid diagnosis of this 

 and the other foreign diseases in the event of 

 outbreaks here. 



The Center's program is flexible enough to 

 allow the study of additional disease problems 

 when necessary. An outbreak of duck virus 

 enteritis (duck plague), in the Long Island duck 

 industry, necessitated a comprehensive study of 

 this disease. When hog cholera is officially 

 eradicated from this country, it also will be 

 added to the list of foreign diseases to be studied 

 and diagnosed. 



GENERAL AREAS OF RESEARCH 



Research at the Center has been divided into 

 five general areas. These areas broadly corres- 

 pond to the work of five different research 

 groups, or disciplines. The general areas of 

 research are as follows. 



Viruses 



(1) Biophysics 



(2) Protein coat structure 



(3) Nucleic acid structure 



(4) Synthesis 



(5) Antiviral agents 

 Vaccines 



(1) Virus production 



(2) Inactivants 



(3) Adjuvants 



(4) Safety and serologic testing 



(5) Immunity challenge
