=Marseilles Swine Plague Bacillus.= This microbe was found by Rietsch and Jobert in a febrile epizoötic of swine at Marseilles, and was studied by Caneva and Bunzl-Federn separately. The latter identified it with the bacillus of ferret septicæmia, as described by Eberth and Schimmelbusch. It was longer and thicker than the hog cholera bacillus, twice as long as broad, actively motile, with flagella, and differed from bacillus choleræ suis, in its polar staining, its free growth in acid media, in acidifying and coagulating milk, and in its forming both indol and phenol in peptonized bouillon. In this case the source of the disease was in importations from Africa (Fouquet), and it spread widely in Southern France for nine months. It proved almost constantly fatal, in from four days to two or three weeks. The symptoms were weakness especially in the hind limbs, with more or less fever, constipation often followed by diarrhœa, an infrequent cough, and red blotches on the skin. In chronic cases ulcers formed in the mouth and intestines especially the cæcum and colon. Appetite was often retained to the end. The young, under a year old, were the chief sufferers. It made 20,000 victims in several months in the province of Bouches-du-Rhone. SEPTICÆMIA HÆMORRHAGICA OF BOVINE ANIMALS. Synonyms. Definition. Historic notes. Resemblance to black quarter. Bacteriology; saprophytic cocco-bacillus, nonmotile, ærobic, related to microbe of swine plague, chicken cholera, and rabbit septicæmia. Pathogenic to deer, buffalo, cattle, horses, swine, rabbits, rats, mice, goats, and sheep. Variability. Vitality: great in soil, dies in 6 to 20 days when dried, and quickly in antiseptics, resistant to heat. Accessory causes: rise of soil water in winter or in spring, drying of marshes in summer, wet, rich, swampy, mucky soils; youth, gregariousness, carnivorous habit, insects, vermin, wild animals and birds, epizoa, entozoa, wire fences, wounds of all kinds, hard, woody provender; inoculations in wounds the most fatal. Symptoms: superficial with hyperthermia, functional disorder; muscular tremors; violet mucosæ; segregation; swelling in intermaxillary space, tongue, throat, neck, dewlap, or elsewhere, not pitting on pressure. Petechiæ. Death in six hours to four days; thoracic form kills in four to eight days; abdominal form with colics, and bloody often frothy fœtid fæces. Chronic forms usually pulmonary. Lesions: straw-colored exudations subcutem or intramuscular; blood extravasations; in lungs resembles lung plague; on bowels blood effusions, and exudates; softened, blood-stained lymph glands. Spleen usually normal in size. Blood black. Petechiæ extensive. Chronic lesions. Bacillus in exudate, blood and bronchial mucus. Diagnosis: from anthrax, black quarter, lung plague, rinderpest, and malignant œdema. Mortality 50 to 80 per cent.
