Canine filariae coiled around the Chordae tendineae of the right ventricle in 13 of 278 dogs subjected to autopsy at the author's laboratory over a 3-year period beginning with April, 1964. The 13 dogs showed essentially the same general signs as those of chronic filariasis, such as congestion and enlargement of the liver, ascites, embolism of branches of the pulmonary artery by worms, and dilatation of this artery with roughened endothelium. Six of the 13 dogs were examined histo-pathologically. In 4 dogs, the coiling worms retained their normal structure well, causing thrombosis, swelling and loosening of tissues, and mild cellular infiltration. In the other 2 dogs, the coiling worms presented a very obscure structure, inducing the appearance of giant cells against foreign body and numerous plasma cells.
Dairy cows showing prolapse of the vagina at the time of slaughter were examined for histopathological changes in the sacral nerve. All of them exhibited such changes of neuritis as degeneration and disappearance of nerve cells in the ganglion, proliferation of stellate cells, infiltration of lymphocytes and eosinophils around nerve bundles, and swelling, demyelination, and vacuolation of nerve fibers. On the other hand, these changes were very mild in the sacral nerve of dairy cows free from prolapse of the vagina. In conclusion, the pathogenesis of this disorder in dairy cows consists in autonomic nerve disturbances accompanied by organic changes of those nerves distributed in the vagina and vulva.
Cabbage and carrot were boiled, cooled, and mixed with sliced dried bonito for a school lunch program in Kazo, Saitama, in October, 1969. Of 992 persons who had had lunch, 775 persons (78.1 %) were involved in food poisoning, manifesting fever, diarrhea, celialgia, vomiting, and headache. The incubation period ranged from 3 to 79 hours, mostly 25 hours. Salmonella enteritidis was isolated from the feces of the patients, the preserred specimen of the lunch, and the remainder of dried bonito. It was presumed that the incriminated dried bonito might have been contaminated with 100, 000 to 1, 000, 000 Salmonella organisms per gram when served as lunch.
