FORTIETH BIENNIAL REPORT 



71 



DISEASE LABORATORY 



The disease laboratory, a bureau function located in Strawberry 

 Canyon on the campus of the University of California in Berkeley, has 

 expanded its program but the working space is inadequate. Under the 

 direction of Dr. C. M. Herman the staff discovered pullorum, a serious 

 intestinal disease, among the state game farm pheasants in the spring of 

 1947. That fall an extensive control program was initiated with the result 

 that the disease was eradicated. An outbreak of infectious coryza was 

 found in one of the game farm units and the disease was eradicated.

 of Game Conservation is equipped for on-the-spot investigations and autopsies in the 

 field. Speedy diagnosis of wildlife diseases enables the division to inaugurate control 



measures without delay 



Investigation of reported hoof and mouth disease in deer in several 

 local outbreaks disclosed the disease to be foot-rot. Work on this is being 

 continued as cases occur. This was an infection caused by anaerobic bac- 

 teria produced in waterholes which were at a low level because of scant 

 rainfall. 



Many other studies were in progress at the close of the biennium and 

 outbreaks of game diseases were investigated both in the field and the 

 laboratory upon their occurrence.
