JOURNAL FREE ACCESSProphylactic effect of levamisole hydrochloride to the developing stages of Dirofilaria immitis was studied in both the experimental and the field trials.
Experimental trials: Dogs were medicated orally with 2.5mg/kg/day of levamisole hydrochloride for 30days after experimental infection. They were sacrificed on the 143rd day of infection, but no worms were recovered from their right ventricles or pulmonary arteries. In non-medicated controls the mean recovery rate was 40.9%.
Field trials: Dogs were exposed to natural infection throughout the infectious season and additionally inoculated once with infective larvae to establish the infection steadily. They were divided into two groups. One group of nine dogs were orally given 2.5mg/kg/day of the drug every day for 6months, from June to November. The other group of three dogs were medicated in the same manner, except the drug was given every other day. Both groups were sacrificed at 151 or 152days after inoculation. Of them, 12 dogs had no worms. Three controls had 15 to 66worms, showing a mean recovery rate of 72.7%. No adverse reaction of this drug was recognized in any dogs.View full abstractDownload PDF (682K) -

JOURNAL FREE ACCESSA study was carried out to evaluate the therapeutic effect of BPMC (2-sec-butylphenyl-N-methylcarbamate) on calves affected with ringworm. These calves harboredTrichophyton verrucosumwhich was isolated from skin lesions, and showed keratinization in the horny layer, hyperplasia and edema in the germinal layer of the epidermis, and proliferation of fungi in hair follicles.
After the topical treatment with BPMC once a week for 3 or 4 cosecutive weeks, no fungi were isolated from the lesions, from which the histopathological changes disappeared. It was confirmed that BPMC was very effective against ringworm in calves.View full abstractDownload PDF (10738K) -

JOURNAL FREE ACCESSNineteen cows on a farm were examined periodically with the following results.
1) The positive rate of Fasciola sp. eggs in feces decreased drastically after treatment with a vermicide, and began to increase gradually three to five months after treatment.
2) There was a difference in precipitating antibody titer (geometric mean) between sera collected from the cows in October after treatment with the vermicide and those from the cows in April after treatment. This result seems to be related with the presence of larvae after treatment. There was an individual difference in the rate and period of increase in precipitating antibody titer.
3) In cows treated with the vermicide only in October, α- andβ-globulin increased, and albumin and A/G ratio decreased in serum concurrently with the detection of Fasciola Sp. eggs in feces. GOT, α-globulin and total cholesterol incrcased in value significantly in each cow around the time when antibody titer incrcased.View full abstractDownload PDF (918K) -

JOURNAL FREE ACCESSA survey was conducted on the water pollution of the Arakawa River by examining pyrogen contents and bacterial contamination. Ten samples were collected from rural and urban areas and analysed by the Japanese pyrogen test (PT), Limulus test (LT), and synthetic chromogenic substrate test (ST) for pyrogen contents. Simultaneously, they were examined for total colonies (TC), psychrotrophic bacteria (PB), coliforms (CF), and Gram-negative bacteria (GB). The results obtained are as follows.
CF, GB, PB and TC of the river water showed a tendency to increase gradually toward the urban area (TC, ranging from 0 to 25, 000/ml;PB, 10 to 40, 000/ml;CF, 0 to 410/ml;GB, 0 to 17, 000/ml).
PT of the river water showed a tendency for pyrogen contents to increase gradually toward the urban area.LT of the river water showed a tendency for endotoxin contents to increase gradually toward the urban area. ST ranged from 6 to 426ng/ml. The results of PT tended to be parallel to those of LT.View full abstractDownload PDF (792K) -

JOURNAL FREE ACCESSSerum and blood samples were collected from 40 steers of 1, 3, 6 or 12months old and two male newborn goats. Ceruloplasmin was measured with its oxidase activity as an indicator. In the steers, serum ceruloplasmin increased with growth and was correlated significantly (p<0.01) with serum copper, iron, total protein and hemoglobin. In the goats, serum ceruloplasmin increased gradually after birth for 32days of observatio.View full abstractDownload PDF (458K) -

JOURNAL FREE ACCESSOver a period from 1981 to 1983, 270 feral pigeons (Columba livia domestica) were captured at 5 areas of Nagoya and Inuyama. Of them, forty were infested with Tetrameres fissispina, which was identified by Dr. S. L. Eduardo, the College of Veterinary Medicine, University of the Philippines System, Quezon City, Philippines. A typical reddish cyst was observed in the wall of the proventriculus. It was a female body itself. Number of cysts per the proventriculus ranged from 1 to more than 50, increasing with the advance in growth of the pigeon. Especially, heavy infbstations did occur in adult birds.
A rate of infestation range from 8% to 33% depending upon the area pigeons inhabit. The average rate of infestation among the birds captured in the Nagoya areas was 15%. It was significantly higher than those among feral pigeons in Tokyo or some other areas. The significance of such topographical difference in the infestation rate was discussed.View full abstractDownload PDF (2654K) -

JOURNAL FREE ACCESSIn November, 1983, 34 Japanese Black beef cattle approximately 12months old were purchased from Hokkaido and introduced in to a farm in Nagano Prefecture. Of them, six died within the first 16days. Of them, three manifested respiratory symptoms for 4-5days before death. The other three died suddenly without showing any specific symptom.
When examined, one of the former three was affected with severe fibrinous necrotic pneumonia. Pasteurella multocida was isolated from its lungs and the nasal discharge of some surviving cattle showing respiratory symptoms, as well asparainfluenzavirustype3. The respiratory disease was diagnosed as a double infection withP. multocidaandparainfluenza virus type3.View full abstractDownload PDF (3440K) -

JOURNAL FREE ACCESSAntibodies against infectious pancreatic necrosis virus (IPNV) and infectious hematopoietic necrosis virus (IHNV) were detected in wild waterfowls (mainly ducks) examined in Hokkaid oover a period from 1977 to 1980. In the immunodiffusion (ID) test, 58.1% and 3.2% of the sera of the waterfowls formed precipitin lines against at least one of the 5 strains of IPNV and 1 strain of IHNV, respectively. The positive sera neutralized the 5 strains of IPNV with very low neutralizing titers. No precipitin line against IPNV or IHNV was observed in the ID test of sera collected from minks fed minced fish meat.
No virus was recovered from duck embryos experimentally inoculated with IPNV and IHNV. When mice, nude mice, and rabbits were inoculated with these viruses, they showed no clinical signs. In them, no viruses were recovered from the blood, oral or rectal swabs, or any internal organ. No cytopathic effect was observed in any mammalian line cells inoculated with IPNV or IHNV. Thus, there is a possibility that feral ducks may be infected naturally with IPNV or IHNV, but the possibility for mammals and wild birds, other than waterfowls, to be infected with these viruses seems to be negligible. The role of wild waterfowls in the viral transmission was discussed.View full abstractDownload PDF (2721K) -
