JOURNAL FREE ACCESSThe author previously devised an apparatus that displayed a remarkable effect when used inthoracotomy in cattle. The first type of this apparatus used pressed air (1954), the second type pressed oxygen (1955), and the third type a closed circuit system (1955-1962). In the present study, an anesthetic apparatus with a closed circuit system was developed for large animals. It had a fitted artificial respiration unit. The new apparatus had the following points improved.
1. The tracheal tubes were made shorter (to 100 cm) and wider (1.7, 2.5, and 3.2 cm in inside diameter). The resliration tube inlet and outle was a winding one 4.5 cm in inside diameter and 160 cm in length. Two respiration bags 20 and 40 liters in capacity were prepared.
2. The dry flow meter for circuit oxygen was graduated 1-15 liters and 13-30 liters per minute, the vaporizer 100-2, 500 ml per minute, and stickoxydul 1-15 liters per minute.
3. Acooper kettle 350 ml in capacity was used for the maintenance of ether and halothane during the induction of anesthesia. Fluotec (Fluoretter) 135 ml in capacity was uesd for the maintenance of anesthesia with halothane. Halothane concentration was measured by a fluothane-meter.View full abstractDownload PDF (8008K) -

JOURNAL FREE ACCESSIn spring and early summer in 1968, Salmonella typhimurium infection occurred in a herd of growing dairy cattle consisting of 118 calves and 16 cows in Fukui Prefecture. More than half the animals of the herd suffered from diarrhea. Main clinical signs were anorexia, depression, slight weakness accompanied by fetid, whitish-yellow, watery diarrhea' Insome cases, blood and mucus were contained in feces. All the animals recovered from the disease, except ten calves less than 20 days old which died within several days after clinical manifestation.
Postmortem examination revealed that the small intestine was dilated and filled with large amounts of milky and whitish-yellow contents. The wall of the small intestine was remarkably thinned out. Swelling of the mesenteric lymph nodes, and mild cloudy swelling of the liver and kidney were also observed.
Histological findings were characterized by catarrhal enteritis with necrosis of the mucous membrane of the small intestine, activation of the reticuloendothelial system, and focal necrosis of the liver. Thrombosis which included a bacterial mass was recognized in small blood vessels in many organs.
Salmonella typhimurium was isolated from the liver, spleen, mesenteric lymph nodes, and intestinal contents of a dead calf, and from the rectal feces of 14 animals (11.3%) out of 124.
The Widal reaction was carried out on sera of all the animals of the herd, by using an antigen prepared. from Salmonellatyphimurium isolated from the mesenteric lymph nodes of a dead calf. As a result, 1: 80 or higher titers were given by about 23% of the tested animals. It was noticed that highly positive reactors were among animalswhich had already recovered from the disease.View full abstractDownload PDF (4497K) -

JOURNAL FREE ACCESSA total number of 57 strains of Erysipelothrix insidiosaisolated from swine erysipelas (including 3 strains of stock cultures) were examined for sensitivity to 26 antibacterial drugs by means of a plate dilution method.
1) All the strains tested were completely sensitive to penicillin G, aminobenzyl penicillin, phenoxyethyl penicillin, methylchlorophenylisoxazolyl penicillin, erythromycin, and tylosin. Most of them were fairly sensitiveto spiramycin, leucomycin, oleandomycin, mikamycin, and the tetracyclines, as compared with the other drugs.
2) A very few of the strains tested were sensitive to chloramphenicol, thiophenicol, streptomycin, and dihydrostreptomycin. Furthermore, few of them were sensitive to novobiocin, fradiomycin, kanamycin, polymyxin, colistin, and sulfa drugs.
3) There were no differences in sensitivity to many of the drugs tested among the strains isolated from septicemic, endocardiac, and arthritic forms.
4) It was difficult to make anyof the strains resistant to penicillin G by means of an artificial process in vitro.View full abstractDownload PDF (913K) -
