134 ANNUAL REPORT OP THE Olt. DOC. 



ANTHRAX 



Of thirty-one specimeus recciNed for exaniiiiarion all except one 

 were from cattle. The diaguosis depended upon: 



1. The demonstration of anthrax bacilli in smears of blood. 



2. The examinaticm of twenty-four hour cultures made from the 

 blood or tissues. 



3. The inoculation of mice with suspected material. 



4. Precipitin test after Ascoli. 



These specimens included sections of muscle, liver, spleen, and in 

 the majority of cases whole ears. Of the number received ten were 

 diagnosed positive. To avoid any errors in diagnosis the demonstra- 

 tion of bacilli resembling anthrax was followed by inoculation with 

 tissues. By this means we were enabled to isolate several new strains 

 which were kept yi stock and used in the preparation of the difterent 

 anthrax vaccines. 



"EPIZOOTIC LYMPHANGITIS" 



Of the total number of eight specimens received it was possible 

 to demonstrate the double membraned spores of Sporothrix (sac- 

 charomyces farciminosusj in but two instances. Unstained prepara- 

 tions fixed in Ernst solution show these bodies particularly tine. 



CHRONIC BACTERIAL DYSENTERY 



Six specimens of tissue, rectal scrapings, and feces were received 

 and examined. Of these tive were negative and one positive. 



SYMPTOMATIC ANTHRAX OR BLACKLEG 



One specimen suspected of this disease Avas a portion of muscle 

 from a calf, and with it we were able to reproduce the disease. The 

 bacillus of sj^mptomatic anthrax was also successfully demonstrated 

 in smears from the tissue received, and from cultures. 



POULTRY 



Forty-eight fowls were received during the year, including twenty- 

 three living and twelve dead hens, tive living and three dead ducks, 

 four dead guinea hens and one living squab, together with five ditfer- 

 ent specimens of tissue. Some of the animals received showed typical 

 lesions of roup and were diagnosed as such. Some recovered com- 

 pletely, and were either destroyed, returned, or kept for observation. 

 During the summer many chickens were received which showed the 

 following symptoms:— loss of appetite and coordination, drooping 

 of wings, anemia of the mucous membranes, coma, and diarrhoea, and 

 the autopsies revealed nothing but a catarrhal hastro-enteritis. 



MISCELLANEOUS 



The remaining specimens received, fifty in number, were diagnosed 

 as follows: — Forage poisoning, Borna's disease, Texas fever, cow 

 pox, navel ill, croupous and broncho-pneumonia, invaginations, rup- 

 ture, traumatic pericarditis, osteomalacia, streptococcic or straphlo- 

 coccis infections, tumors, including lymphoma, fibromyxoma, hard 

 fibroms and round cell sarcoma, parasitic infections including oesopho- 

 gostomum columianum, trichophytom tonsurans, cystocercus-pisifor- 

 mis, rhipicephalus sanguineus, boophilus annulatus, demondex folli- 

 culurum, larvae of the hypoderma bovis, strongylus filiria, etc.
