JOURNAL FREE ACCESSTrimenol Powder (TA-068), a compound of sulfadimethoxine and trimethoprim, was administered to piglets affected experimentlly with colibacillary diarrhea. Therapeutic effect was revealed by administration with doses of 300 to 500mg/kg/day for 3days. When doses of 100, 300 and 500mg/kg/day were orally given to 74 critical and 54 non-critical piglets for 3 to 5days, rate of healing and rate of prevention were 37.5%, and 89.5%, 91.9% and 100%, and 90.5% and 100% at the three doses, respectively. High therapeutic and preventive effects were obtained with both 300 and 500mg/kg/day.
Escherichia coli separated from diarrheal stool showed a high sensitivity to TA-068. Especially, its strains resistanto some other antibacterial agents were highly sensitive to TA-068.View full abstractDownload PDF (773K) -

JOURNAL FREE ACCESSMilbemycin D (MD)(Sankyo Co., Ltd., Tokyo) is a compound produced by Streptomyces hygroscopicus subsp. aureolacrimosus. Over a period from April, 1983, to May, 1984, 92 apparently healthy dogs were examined in ten veterinary clinics, nine in Tolyo and one in Nagoya. Dirofilaria immitis infection was enzootic in both cities. All the dogs were negative for microfilariae in blood at the time of the initial examination. Each dog was administered orally with 0.1g/kg of MD (powder concentrated 100times) enclosed in a gelatin capsule or wrapped in a piece of gelatin sheet once a month over a period from April to December, 1983. All the dogs, except one, were ready to take the drug every month and remained free from any adverse effect of the drug and any danger of treatment. The exceptional dog vomited three times after the initial administration and was discarded from the experiment. The 91 dogs were all negative for microfilariae in blood up to May, 1984, when the experiment ended. It was demonstrated clinically that MD had a preventive effect against D. immitis infection.View full abstractDownload PDF (655K) -

JOURNAL FREE ACCESSA preliminary exposure to Theileria sergenti by inoculation with infected bovine blood was suspected to be a cause of artificial transmission of bovine leukemia virus (BLV) among cattle. To check the incidence of BLV infection, serum samples were collected, over a period from 1968 to 1979, from 304 cattle in 21 pastures and 37 experimental areas in total (before and after preliminary infection). The presence of antibody against BLV was determined by the agar gel immunodiffusion test.
The rate of antibody prevalence was low in herds inoculated with blood vaccine prepared in essentially the same manner as the authorized biological products, as well as in uninoculated control herds. No significant difference was observed between the two herds.
In other herds, however, where cattle were inoculated with blood vaccines which had not so carefully been prepared, the antibody prevalence increased. There was a significant difference in the prevalence between these herds and the herd inoculated with the former blood vaccine. It was suggested that the transmission of BLV by the blood vaccine was controlled when the donor was carefully selected and supervised.View full abstractDownload PDF (737K) -

JOURNAL FREE ACCESSA serological survey for antibodies against feline and other animal viruses was conducted on 231 cat sera collected from various districts in Japan. Serum neutralization and microplate hemaggluttination inhibition techniquse were used. Of the sera, 169 (73.2%) were positive for antibody against feline viruses and 35 (70%) of 50 sera against some other animal viruses.
On the 231 sera, 142 (61.5%) had antibody against feline panleukopenia virus, 40 (17.3%) against feline rhinotracheitis virus, and 169 (74.0%) against feline calicivirus.
Besides, 56% was positive for canine parvovirus, 10% for canine parainfluenza 5 virus, and 4.0% for canine distemper virus. There were significant regional differences especially in the frequencies of the latter 2 viruses.
When 50 sera were selected at random, all were negative for antibodies against Japanese encephlitis and swine influenza viruses.View full abstractDownload PDF (3260K) -

JOURNAL FREE ACCESSThe Nitroblue tetrazoliumdye (NBT) test was carried out in cattle and swine affected with various diseases.
The NBT positive rate was 4-8% in normal cattle and swine. It decreased in cattle infected with infectious bovine rhinotracheites virus. It was more than 15% in cattle infected with Haemophilus somnus or some other bacteria. It decreased in swine infected with hog cholera virus. It was more than 15% in swine infected with Pasteurella, Haemophilus or some other bacteria.View full abstractDownload PDF (1827K) -

JOURNAL FREE ACCESSWhen milk from each quarter was examined in lactating cows, Pseudomonas aeruginosa was detected from most of the quarters. It belonged to serotype II-B or III-G. It was also detected from the granulation tissue of mastitis quarters and the tissue of normal quarters of a killed cow. It belonged to the same serotypes as mentioned above.
The isolated strains were sensitive to Colistin, Polymyxin B., Chloramphenicol, Oxytetracycline, and Tetracycline.View full abstractDownload PDF (656K) -

JOURNAL FREE ACCESSIn November, 1983, Japanese Black beef cattle approximately 12 months old were purchased from Hokkaido and brought so a farm in the Matsumoto area. Within 16days, six died. Of them, three died suddenly, showing no specific symptoms and the other three showed respiratory symptoms for 4-5days before death.
Autopsy on one of the former three revealed severe hemorrhage in the small intestine. The mucous membrane was necrotic and the liver had many necrotic foci. Toxic Clostridium perfringens type A (10 9.3/g) and a minute quantity of coccidial oocysts (Eimeria bovis) were found in the intestinal contents. No viruses were isolated. The disease was diagnosed as necrotic enteritis induced by C. perfringens type A.View full abstractDownload PDF (3841K) -
