SEPTICEMIA HEMORRHAGICA OF THE SHEEP : 



I^OMBRIZ. 



Synonyms. Definition. Geographical distribution , Argentina, Fran ce, etc. 

 Causes : bacillus ; intravenously, etc., youth, verminous affections, low condi- 

 tion. Bacteriology : ovoid bacillus with polar stain, bleached by Gram's solu- 

 tion, aerobic, non-motile. Symptoms : Chronic form in summer, diarrhoea, 

 arched back, stiffness, emaciation, flattened wool, segregation, impaired or 

 depraved appetite, shedding wool, anaemic skin, dependent dropsies, sunken 

 eyes, weak small pulse, temperature variable — elevated, nasal and buccal 

 discharge, weakness, paresis, dullness, torpor, lung symptoms, arthritis. 

 Diagnosis : from distomatosis and strongylosis. Acute form with high fe- 

 ver, constitutional disorder, colics, diarrhoea, death in 24 to 36 hours, sub- 

 acute form. I<esions : black blood, congestions, and general petechias. 

 Lungs, liver, kidneys and spleen, congested, swollen. Subacute cases have 

 lighter blood, and lesions. Chronic cases anaemic, blood diffluent, lymph 

 glands enlarged, congested ; connective tissues and serous cavities dropsical, 

 gastric, intestinal and hepatic worms, spleen shrunken. Mortality : great in 

 acute, less in chronic. Prevention : segregation, exclusion of all sheep from 

 unknown or suspected flocks, antiseptic dip and quarantine for new pur- 

 chase^, expose a few as a test ; cleanliness, disinfectants, avoid watershed 

 from infected lands, wide range, out- door life, generous diet, remove weak, 

 emaciated, anaemic. Immunization. Treatment. 



Synonyms. Pasteurellosis Ovina. Infectious Pneumo- Enteri- 

 tis. 



Definition. An infectious febrile affection of the sheep, chronic 

 or acute, characterized by dulness, stiffness, or paresis, anorexia, 

 thirst, disorder of the breathing and digestive organs, black dif- 

 fluent blood, petechise, reddish effusions in the serosse or connec- 

 tive tissue, and congestive or inflammatory lesions of the lungs, 

 liver, kidneys and intestines. The presence of a cocco-bacillus 

 (diplo- coccus, strepto-cocco-bacillus, Pasteur ellosa) in the lesions 

 is especially characteristic. 



Geographical Distribution. Though lyignieres first demonstra- 

 ted this as a bacteridian disease in the Argentine Republic, he 

 was, after his return, able to identify the same affection in the 

 flocks of almost every department of France, in newly imported 

 English lyincolns, and German Merinos, so that there can be 

 little doubt that the malady exists in all or nearly all countries 

 engaged in sheep husbandry, though it has been usually attribu- 

 ted to parasitisms of the lungs, liver or alimentary canal alone.
