Continuous feed medication with nitroscanate for the removal of Hymenolepis nana in naturally infected mice and rats.     

B G?nen?  H O Sarimehmeto?lu 《DTW. Deutsche tier?rztliche Wochenschrift》2001,108(10):434-436

In this study, the effects of nitroscanate were investigated in naturally acquired Hymenolepis nana infections in rats and mice. The natural infection was determined by centrifugal flotation technique of faeces. The infected rats and mice were divided into two treatment and two control groups (N = 10). Nitroscanate at the dose of 50 mg/kg per day was given in the diet for 4 days. The rats and mice of treatment groups were necropsied on 7th day after the last treatment together with those of control groups. Following necrospsy, in the treatment group a geometric mean of 1.07 Hymenolepis nana were recovered out of ten mice, compared with 8.14 in the control group. In the rat treatment group no Hymenolepis nana were found in ten rats, while the control group showed a geometric mean of 6.23. Nitroscanate was found to be effective 100% and 86.8% at the treatment of H. nana infection in rats and mice respectively.  相似文献

Immunohistochemical localization of matrix proteins in the femoral joint cartilage of growing commercial pigs.     

S Ekman  D Heineg?rd 《Veterinary pathology》1992,29(6):514-520

The immunocytochemical localization of several matrix macromolecules, including collagen type II and proteoglycans, in the distal femoral articular-epiphyseal cartilage complex of 15 commercial pigs between the age of 6 and 18 weeks was studied. Early osteochondrotic lesions, i.e., chondronecrosis in the resting region of the growth cartilage, as well as extensions of necrotic cartilage into the subchondral bone, were present in all animals, except those 6 weeks old. A battery of antibodies were used for identification of macromolecules in the matrix at different stages of the disease. Chondrocyte involvement in the process could be studied by identifying the sequence of alterations in matrix macromolecules as the lesion developed. The immunostaining for aggrecan (large aggregating proteoglycans), cartilage oligomeric matrix protein, fibronectin, collagen type II, fibromodulin, and biglycan was more prominent in the areas of chondronecrosis, extending into the subchondral bone, than in the normal resting region. This altered pattern of matrix macromolecules resembled that of the matrix of the proliferative chondrocytes and suggests that the chondrocyte maturation had stopped in the proliferative zone. The matrix in the areas of chondronecrosis in the resting region resembled that in the normal resting region. Thus the chondronecrosis appears to have preceded alterations of the matrix composition. The antibody reactivity pattern was, however, altered in the matrix of the clustered chondrocytes in areas of chondronecrosis. Staining in these regions suggested a more prominent appearance of fibronectin and collagen type II than in the normal matrix of the resting region. These changes are suggestive of attempt to repair.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献   

Ochratoxigenic moulds and ochratoxin A in forages and grain feeds.     

M Skrinjar  R D Stubblefield  I F Vujici? 《Acta veterinaria Hungarica》1992,40(3):185-190

The contamination of forages and grain feeds with ochratoxigenic moulds and ochratoxin A was examined. The investigations were carried out over a period of three years in all seasons. Feeds were found to be contaminated with moulds at a high level throughout the three research years. The highest percentage (95 to 100) of contaminated feed samples was noticed during the second year. Total viable counts of moulds established in 1 g of feed samples ranged from 0.5 to 7.8 x 10(6). Penicillium spp. were dominant in mycopopulations isolated from feeds. Ochratoxin-A producing moulds were present permanently. In the summer period of the second research year as much as 94% of the feed samples were contaminated by ochratoxigenic Penicillium species. P. verrucosum var. cyclopium P. verrucosum var. verrucosum, P. commune and P. chrysogenum, i.e. ochratoxin-producing moulds, were the most prevalent Penicillium species throughout the three-year investigation. Ochratoxin A was found in various feeds in all seasons, except in summer of the first research year. Concentrations of the toxin varied from traces to 400 micrograms/kg. It occurred consistently in the same types of feeds (hay, dried alfalfa, fresh alfalfa, concentrate, pelleted sugar beet pulp, corn silage).  相似文献   

Resistance to tick-borne fever in young lambs.     

S Stuen  F Hardeng  H J Larsen 《Research in veterinary science》1992,52(2):211-216

Lambs were inoculated with Ehrlichia phagocytophila infected blood at the age of either two or six weeks. The temperature response and degree of parasitaemia were both most pronounced in the lambs inoculated at six weeks old. The half-life of antibodies to E phagocytophila was estimated to be 17.5 days. Lambs inoculated with tick-borne fever (TBF) had lower liveweights in the autumn than TBF-free controls.  相似文献   

The extraction particles from winter rapeseed with different glucosinolate fractions in swine with regard to the iodine supply. 3. Apparent digestibility of crude nutrients with special regard to the carbohydrate and nitrogen balance]     

F Sch?ne  H Lüdke  A Schneider  R Zander  A Hennig 《Archives of Animal Nutrition》1992,42(1):11-24

In two digestibility and N-balance experiments the following solvent extracted meals were examined in a grain (barley and wheat in equal parts) or in a starch diet with four female pigs/group fitted with urethra catheters during the 5 days sampling period: 48% soyabean meal (SBM) (1), 24% conventional rapeseed meal (RSM) (2), 24 (3) or 48% (4) RSM from a newly bred low glucosinolate variety, groups 1 to 4 with grain, 48% low glucosinolate RSM (5) or 48% SBM (6) both with starch. In numeric order of the groups 88, 85, 86, 84, 79 and 89% N were digested. Pigs responded to the additional faecal N excretion from RSM diets by a lower urinary N excretion and thus they reached the N-balance of the animals fed on SBM. In numeric order of the groups 86, 79, 80, 73, 73 and 92% of the organic matter of the solvent extracted meals were digested. In comparison with SBM even 48% RSM in the feed significantly lowered the digestibility of organic matter. Using detergents the additional faecal organic matter excretion of RSM versus SBM could quantified as two third lignin. In the case of 24% RSM in the diet--i.e. 15% of the carbohydrates given--the carbohydrate digestibility is estimated with a high error, that an energetic feed value should not calculated. Investigating 48% SBM or RSM respectively in a grain diet the net energy content was 9.8 MJ (666 Energetic Feed Units, EFU pig) or 8.3 MJ (569 EFU pig)/kg dry matter (DM). Based on the starch diet, however, little relevant for estimation of normal pig diets, there were evaluated 10.6 MJ (720 EFU pig) for SBM and 8.3 MJ (567 EFU pig) net energy/kg DM for RSM.  相似文献   

Chronic valvular disease in the cavalier King Charles spaniel in Sweden.     

J H?ggstr?m  K Hansson  C Kvart  L Swenson 《The Veterinary record》1992,131(24):549-553

The prevalence of chronic valvular disease was studied in 494 cavalier King Charles spaniels with a mean (+/- sd) age of 3.0 +/- 2.7 years. Cardiac murmurs were detected in 65 (13.2 per cent) of the dogs. Among 61 cavalier King Charles spaniels with a mean age of 6.4 +/- 2.8 years, cardiac murmurs were detected in 32 (52 per cent). In both groups of dogs the prevalence of cardiac murmurs was low among dogs younger than three years (1.9 per cent) but increased with age (P < 0.001). The estimated ages at which 50 per cent of the dogs had developed murmurs were 7.5 and 6.2 years, respectively. When 39 of the 61 dogs were re-examined three years later, cardiac murmurs were detected in 28 (72 per cent), and the intensities of the murmurs had generally increased (P < 0.05). Nine (28 per cent) of the dogs which had previously had murmurs had been euthanased for signs of congestive heart failure whereas none of the dogs which had been free of murmurs had died from congestive heart failure. Animal insurance statistics from 1982 to 1990 (1983 excluded) for dogs less than 10 years old showed that claims for veterinary care or death or euthanasia were five times more common in the cavalier King Charles spaniel than in dachshunds (P < 0.001) and eight times more common than the mean for all other insured breeds (P < 0.001).  相似文献

A globular periodontal cementous dysplasia in a 18 years old black rhinoceros (Diceros bicornis) is diagnosed by gross pathology, X-ray, and by histological examinations. The findings are discussed.  相似文献
