Verminous (Strongylus vulgaris) myelitis in a donkey     

I G Mayhew  B D Brewer  M K Reinhard  E C Greiner 《The Cornell veterinarian》1984,74(1):30-37

A fifth stage Strongylus vulgaris migrated through the spinal cord of a 2-year-old, male donkey resulting in progressive paraparesis and then tetraplegia. A profound neutrophilic pleocytosis was detected on analysis of cerebrospinal fluid. The parasite appeared to have entered the mid-lumbar spinal cord, migrated to the cranial thoracic segments, exited, then re-entered the spinal cord a few segments craniad. It then traveled further cranially and was found in the third cervical spinal cord segment. Some parts of the lesion were remarkably free from tissue necrosis, hemorrhage and inflammation. Severe granulomatous myelitis with hemorrhage and necrosis were seen at other sites. The latter were quite similar to lesions seen in equine protozoal myeloencephalitis.  相似文献   

Studies on the chemical control of blackgrass (Alopecurus myosuroides Huds.) in winter wheat in the West Midlands     

L. R. K. SCOUREY  I. YOUNG  J. B. PAGE 《Weed Research》1982,22(1):23-26

In trials carried out in 1978–80, blackgrass populations in winter wheat growing on heavy soil were substantially reduced by all chemical treatments tested, the least effective being methabenzthiazuron. Wild oat populations were also reduced by all treatments except chlofop-isobutyl and methabenzthiazuron. On average of the 3 years only metoxuron treatment gave wheat yields significantly higher than the unsprayed crop.  相似文献   

Two Hungarian isolates of cucumber mosaic virus from sweet pepper (Capsicum annuum) and melon (Cucumis melo): Identification and antiserum preparation     

I. Tóbiás  D. Z. Maat  H. Huttinga 《European journal of plant pathology / European Foundation for Plant Pathology》1982,88(5):171-183

Two Hungarian virus isolates from sweet pepper (K8) and melon (S4) were identified as cucumber mosaic virus (CMV) on the basis of host plant reactions and serology. The isolates were purified and antisera prepared. Homologous antiserum titers in double-diffusion tests were 256 (K8) and 512 (S4). They were serologically closely related to each other and to other CMV isolates. On the basis of symptoms they belong to different symptomatological groups of CMV; this was supported by serological properties. Sedimentation coefficients were c. 93 S, at 2 mg ml^–1. Purified preparations, stained with 2% uranyl acetate, showed spherical particles. In ELISA purified preparations reacted with each other's antisera.Samenvatting Twee hongaarse virusisolaten uit paprika (K8) en meloen (S4) werden geïdentificeerd als komkommermozaïekvirus (CMV) met behulp van toetsplanten en serologie. Beide isolaten werden gezuiverd en er werden antisera tegen bereid. De homologe titers van de antisera in de agar-geldiffusietoets bedroegen 256 (K8) en 512 (S4). K8 en S4 waren serologisch nauw verwant aan elkaar, evenals aan andere CMV-isolaten. Op grond van hun symptomen op toetsplanten behoren ze tot verschillende symptomatologische groepen van CMV. Dit laatste werd gesteund door de serologische eigenschappen. Beide isolaten hebben een sedimentatiecoëfficiënt van ca 93 S, bij een concentratie van 2 mg ml^–1. Gezuiverde preparaten, gekleurd met 2% uranylacetaat, bleken bolvormige deeltjes te bevatten. In ELISA reageerden gezuiverde preparaten van K8 en S4 met elkaars antisera.  相似文献

Parental and revertant Brucella canis induced changes in the rabbit.          下载免费PDF全文

I N Egwu  A Korenyi-Both    J Schalles 《Canadian journal of veterinary research》1979,43(2):180-186

Chronic brucellosis was produced in the rabbit by parental and penicillin-induced L-phase revertant of Brucella canis. Animals in the experimental groups were injected with 1.2 x 10(8) organisms/ml of appropriate strains by specified routes at intervals. At a maximum of 12 weeks postinfection, animals were killed and samples were taken for bacteriology, serology, histology, immunofluorescent and electron microscopy. Results revealed faecal shedding in some animals from 72 hours up to three weeks postinfection. High agglutinating antibody titres of 1:1280 were sustained in all infected animals. Histopathological and ultrastructural changes attributed to the invading organisms were apparent and evidence of mitochrondriopathic changes are provided. The implication and indirect role of L-phase in brucellosis are discussed.  相似文献

Successful,repeated non-surgical collection of blastocysts from virgin and repeat breeder heifers     

T. Linares  W. A. King  K. Larsson  I. Gustavsson  A. Bane 《Veterinary research communications》1980,4(1):113-118

A total of 55 non-surgical collections, 7 days after spontaneous heat, was made in 19 heifers. Recovery rate was 57% (17/30) from 10 repeat breeder heifers and 72% (18/25) from 9 virgin heifers, this difference was not significant. Fertilization rate in both groups was 94%. The eggs were always recovered in the first 100 ml of flushing medium. Mean lengths of oestrous cycle after non-surgical collection were, respectively, 16.9 and 18.1 days in repeat breeder and virgin heifers. This difference was not significant. However, the cycle in which the first collection was made was significantly shorter (P<.005) than the cycle immediately before the collections. Only 61% of possible eggs were non-surgically collected from 4 superovulated repeat breeder cows and no further eggs were found after slaughter, one to two hours later.  相似文献
