year. 46 persons were reported bitten by rabid dogs during the 

 year. In most cases the Pasteur treatment was taken, but one man 

 in Johustown refused to take the treatment, afterward developed 

 rabies and died. 2,604 animals were destroyed. The number of 

 cases of rabies has increased year after year for a number of years. 



TEXAS FEVER 



Twelve counties were involved, with two outbreaks of Texas 

 Fever, exposing 1,105 cattle to infection ; of these 41 weie atfected 

 and 18 died. The outbreaks occurred in native cattle that were 

 shipped in cars in which southern cattle had been carried, showing 

 that there was not thorough disinfection. This disease is easily con- 

 trolled in Pennsylvania if the precautions of the Board are ob- 

 served. 



CONTAGIOUS ABORTION 



It has been quits well established through the investigation of 

 Prof. Bang of Denmark, and confirmed by the studies of the Eoyal 

 Commission appointed by King Edward of England, to examine and 

 confirm the evidence, that abortion is due to a bacterium. This 

 bacterium has been isolated from an aborted foetus by this Bureau. 



LABORATORY AND RESEARCH WORK 



During the year the laboratory on the farm has been thoroughly 



equipi^ed and manned with ample and edicient help so that first-class 



work can be done. The work as oiitlinsd and begun is Kesearch 



Experiments, Koutine Work, and Milk Hygiene. Research work is 



being conducted on glanders to confirm certain methods of diagnosis, 



on Epizootic Lj^mpangitis, on Tuberculosis in which the work started 



by Dr. Pearson and continued by Dr. Gilliland, was completed and 



some of the newer methods of Tuberculin Testing are studied; on 



contagious abortion for the purpose of diagnosing the disease, and on 



hog cholera, Texas Fever, forage j>oisoning and plant and feed 



poisoning. 



LABORATORY ROUTINE WORK 



During the year over 900 difi'erent specimens representing the 

 various diseases referred to were received for diagnosis ; 427 heads 

 were received duiing 1911 representing horses, cattle, sheep, hogs, 

 mules, goats, cats, dogs, and one human brain from one of the city 

 hospitals for diagnosis for rabies. 



One hundred and twenty-four specimens were received for diagno- 

 sis for glanders, 60 specimens for diagnosis for hog cholera, 34 

 specimens exclusive of milk samples for diagnosis for tuberculosis, 

 31 specimens for examination for antharx, 8 specimens for diagnosis 

 for epizootic lympangitis, 6 specimens for chronic bacterial dysentery, 

 cne specimen for symptomatic anthrax or blackleg. 



One hundred and ninety-eight thousand seven hundred and twenty 

 cubic centimeters of tuberculin solution were distributed, 2,768 c. c. 

 mallein solution were prepared, 1,671 doses of anthrax vaccine Nos. 

 1 and 2 for cattle, and 51 doses of anthrax vaccine Nos. 1 and 2 for 

 horses were prepared and distributed ; 217,085 c. c. hog cholera 

 serum were prepared and distributed during the year.
