JOURNAL FREE ACCESSA portable ultrasonic linear electronic scanner was used for the detection of the uterus in pregnant sows. No images of the uterus were displayed in the scanned picture of non-pregnant or pregnant sows until day 18 of gestation. On the following day the images of the gravid uterus were first recognized. The gravid uterus increased remarkably in diameter on day 24 of gestation. Fetuses began to be detected in it on day 32 of gestation.View full abstractDownload PDF (8627K) -

JOURNAL FREE ACCESSDay-old chicks were highly susceptible to Pseudomonas aeruginosa isolated from chickens affected with cerebral necrosis when inoculated intracerebrally. In them, fatality was 100% with 102 viable organisms. They decreased gradually in susceptibility when administered subcutaneously, intraperitoneally or orally. Fatality after oral administration was 20% with 108 viable organisms. Deaths usually occurred 5 days postinoculation. Age-dependent susceptibility was also observed.
When administered subcutaneously with 108 viable organisms, chicks 1, 7, 14, and 24 days old presented a fatality of 100, 100, 50, and 10%, respectively. The 50% Lethal dosis of the isolate was 104.6 and 107.5 in day-old chicks and 4-week-old mice, respectively, by the subcutaneous route. Cerebral necrosis similar to that of the field case was reproduced in 4 chicks inoculated subcutaneously with more than 106 viable organisms.View full abstractDownload PDF (3712K) -

JOURNAL FREE ACCESSThe relationship between the bacterial flora on diarrhea of piglets and the climate were investigated. The results obtained are summarized as follows.
In the flora of the feces of piglets, resident organisms were Bacteroidaceae, Lactobacillus, Streptococcus, curved rods, Bifidobacterium, Peptococcaceae, and Escherichia coli. At 8-10 days of age, Clostridium perfringens was not found in the predominant genes.
Rapid recovery from diarrheal feces of piglets showed a decrease in E. coli and an increasing tendency in Lactobacillius, and Bifidobacterium. Few other bacteria showed a great variation among individuals.
In diarrheal piglets, E. coli increased rapidly in the ileum and intestine and lactic acid bacteria decreased in the upper part of the ileum. In one of these piglets C. perfringens seemed to have taken part in the occurrence of colibacillosis.
It was considered that low temperature and high humidity might have stimulated the outbreak of diarrhea of pigiets.View full abstractDownload PDF (893K) -

JOURNAL FREE ACCESSBovine tuberculosis broke out collectively among beef cattle in Kumamoto Prefecture in 1979 and 1980, and 74 cattle were condemned. Bacteriological and pathological examinations were carried out in 6 cattle positive for tuberculin test. Autopsy revealed lesions in lung, liver, stomach, and lymph node in all the cattle. Histologically, tuberculous nodules were formed in most lesions. Their centers showed caseation and were surrounded by proliferating epithelioid cells, including scattered Langhans' cells and a few acid-fast cells. These cells were identified as Mycobacterium bovis on the basis of their biological properties and infectivity to guinea pigs.View full abstractDownload PDF (5472K) -

JOURNAL FREE ACCESSShedding of gravid proglottids of Mesocestoides paucitesticulus continued for 5 to 7 consecutive days and followed by a pause of 13 to 15 days in light infections. It took place every day in heavy infections, but shed proglottids varied in number with the season. Its total number in summer was about twice as large as that in winter.
Eggs in gravid proglottids survived 22 days in winter and only 9 days in summer when kept in water. They survived 32 days in winter and 15 days in summer when kept in atmospheric condition.View full abstractDownload PDF (4640K) -

JOURNAL FREE ACCESSGastric mucormycosis was found in a 4-year-old Large Yorkshire sow. Macroscopically, soybean-sized hemorrhagic necrotic lesions were seen in the fundus ventriculi. Histopathologiccally, infiltration of neutrophils, thrombi, and proliferation of hyphae were seen in these lesions. These hyphae were characteristic of the family Mucoracea.View full abstractDownload PDF (4260K) -
