Since the spring of 1960,an apparently infectious disease has been prevailing among sheep in the range of North-western part of Szechuan,attacking both lambs and adult sheep.The causal bacterium was found to be a streptococcus belonging to the Group C of Lancefleld.It was very similar to Strep.Zoo-epidemicus in several respects except that it did not ferment salicin and caused milk coagulation. The disease usually run an acute course with symptoms of septicemia,causing death in 2-5 days.At other times,it took a subacute form,menifested by rise of temperature,re- duced appetite,cough,lachrimation and profuse nasal discharge which was serious at first, then mucoid and finally muco-purulent.Leucocytosis with left depletion of neutrophils was marked.In this form of disease,most animals died usually in 1-2 weeks. Postmortem examination in acute cases revealed congestion and hemorrhage in internal organs.Spleen was softened and enlarged,and the gall-bladder distended markedly.In sub- acute cases the most prominent changes consisted of serofibrinous pleuro-pneumonia and peritonitis.Lymph nodes were swollen and edematous.Microscopically,there were marked edema and leucocytic infiltration in connective tissues.Parenchymatous organs showed de- generation,cellular infiltration,necrobiosis and hemorrhages of various extent.A great number of streptococcus were seen in the blood,as well as pulmonary and pleural exudates,many of them being found within the phagocytes of various kinds.Toxemia and/or septicemia were as- sumed to be the cause of death.

SUMMARY Penicillin was found to be effective in treating experimentally infected sheep inoculated with the. culture of Streptococcus ovis if used fairly early in the Coursc of disease; while sulfonamides cured only a few. of 42 cases treated with penicillin, all were cured clinically except 1, which died apparently from asphyxia due to excessive oedema in the laryngeal region. However, 10 Sheep among the recoveray animals, under certoin stress, relapsed after a longer or shorter interval of convalescense and died the same infection when theg reeieved no further treatment. Twenty-nine reeoved sheep were killed at various intervals within 1 year since they had been cured , and a thorough search for the evidence of carrier State was made by the cultural toothed. Streptococcus ovis was recovered in 12 carcasses, mostly from the lymph nodes of different regions, a few from the brain, spinal cord, liver, lungs, adrenal glands and nosal passages. The longest interval for the maintenance of the carrier State was found to be 7.5 months. The cultures isolated from the lymph nodes retained avirulence as high as that of the original Strain. The other 24 recovered sheep were challenged with virulent culture, in doses of 10—1000 M.L.D., at various inte rvals 1 year since they had been cured, and all but 1 were well toleraled.

Thirty one appatently healthy sheep were infected intranasally with streptococcus group C,isolated from enzootic streptococcosis of sheep.The dissemination of the infective agent and the alterations in body temperature,blood constituents as wall as anatomical and histological changes were systematically recorded.Twenty four sheep were searificed at 6,12,18,24,36,48,72,108,and 120 hours after infectioil.The remaining seven sheep were kept under observatioil until died them selves. The results indicated that both the course of the disease and the pathological changes after the nasal infection were quite different from that infected by the routes other than the respiratory tract.There were also certain disagreements as well in comparison with the findings obtained threugh intratracheal ineculation,This implied that the portal of infection and the route of dissemination played a major role as far as the course of disease as well as the nature and the localization of the lesions were concerned.The experimentally infected sheep all bagan with naso-pharyngitis and tonsillitis,followed subsequently by the inflammation of the satellite lymph nodes in the naso-pharyngeal region.Finally,all the sheep were succumbed to pyemia-septicemia.As to the cause of the death the bacterial intoxication and breakdown of the defence mechanism of the lymphatic tissue were inerimated on the one hand,while the anoxia brought about by the dyspnea resnlted from swollen larynx was accounted for on the other.

本实验采用滴鼻接种绵羊31头,首次对C组链球菌在体内的播散情况以及在体温、血液和解剖、组织方面引起的变化的发展经过,作了比较系统的观察。分期扑杀羊共24头,计划听任自然病死羊七头,其中死亡的五头,只表现体温反应和血液变化的两头。初步结果如下: (1) 在滴鼻接种后12小时,便可从咽背淋开始获得细菌,到接种后36小时,进一步可在全部颈中淋里发现,到接种后72小时,亦可从其他某些脏器发现细菌。接种后自然病死的绵羊,按计划进行菌检的10个脏器和心血,几乎都可以分离到细菌。败血过程看来是在接种72小时后酿成的。 (2) 在滴鼻接种后24小时检温时,发现分期扑杀绵羊和自然病死绵羊,都由接种前的39℃左右上升到了41°——41.5℃之间,稽留约二日,然后开始降低,但仍停留在40.5℃上下。临死时有的继续下降。 (3) 伴随体温上升,白细胞的总数和多形核的比例都有增加的趋势,嗜伊红白细胞计数则有明显的减少,多形核和淋巴细胞变性形态也逐渐多见。与β球蛋白量出现升高趋势的同时,γ球蛋白量则有降低的倾向。 (3) 细菌在器官组织里所引起的反应,首先的也是最主要的是多形核白细胞浸润,开始在局部淋巴组织以后在其他淋巴结和脾里以弥散状...
