Cryptococcal osteomyelitis in a dog     

M. J. Brearley  N. Jeffery 《The Journal of small animal practice》1992,33(12):601-604

Osteomyelitis caused by Cryptococcus neoformans was diagnosed in a three-year-old male Irish wolfhound. The case details and radiological findings of radiolucency and periosteal reaction of the left third metatarsal bone had lead to an initial diagnosis of a malignant bone tumour. Biopsy revealed a fungal granuloma and culture identified the causal organism. A four month course of ketaconazole was instigated and the lameness resolved. Twelve months after the end of treatment there was no recurrence of the problem.  相似文献

Genotypic Variability in Biomass Protein and Nucleic Acids in Four Linum Species to Sodicity Stress     

A. K. Singh  B. B. Singh 《Journal of Agronomy and Crop Science》1991,167(1):1-7

Differences in gas exchange parameters i.e. carbon exchange rate (CER), transpiration (Tr), water vapor conductance (g) were investigated, under a controlled environment, in a semi-dwarf (SD) Triticum aestivum line, its tall (TL) near isoline and the Payne (PA) variety characterized by small leaves. The plants were maintained in: (a) optimal substrate moisture condition (CTR); (b) salinized by watering with a 0.12 m NaCl solution (SLT); (c) water stressed by withholding waterings during a period of six days (STR); (d) stressed and salinized during the same period and with the same saline solution (S + S). CER and Tr were negatively affected by the stresses; SLT and S + S treatments had a higher WUE compared to their respective controls CTR and STR.
SD line had a better performance in terms of CER and WUE, particularly when water and salt stresses interacted. Leaf anatomy and assimilation/internal CO₂ concentration curves contributed to explaining the SD performance.  相似文献

Antibody response to crustacean ectoparasites in rainbow trout, Oncorhynchus mykiss (Walbaum), immunized with Argulus foliaceus L. antigen extract     

N. RUANE  T. K. MCCARTHY  P. REILLY 《Journal of fish diseases》1995,18(6):529-537

Abstract. A humoral antibody response was demonstrated by ELISA in rainbow trout immunized intraperitoneally with extracts from the branchiuran ectoparasite Argulus foliaceus. A similar immunization protocol produced a higher titre response in a rabbit. Both trout and rabbit identified several antigenic components on immunoblots. ELISA and immunoblotting indicated that rainbow trout and rabbit anti-A. foliaceus sera identified components from the parasitic copepods Lepeophtheirus salmonis and Caligus elongatus.  相似文献

Behaviour of laying hens in a deep litter house   总被引：4，自引：0，他引：4  

M C Appleby  B O Hughes  G S Hogarth 《British poultry science》1989,30(3):545-553

1. Flocks of medium hybrid laying hens were housed in a modified deep litter system; the house was divided into 2, 3 and 4 pens in three successive years. Flock size was 300 or 370 and stocking density varied from 3.4 to 10.7 birds/m2. Higher densities used were above those recommended by the Ministry of Agriculture, Fisheries and Food (MAFF). 2. A random sample of 100 birds was identified with individual tags in each of the 9 flocks; regular observations using a scanning technique were made in each laying cycle to determine bird location and behaviour. 3. In all flocks the use of area by some individuals was uneven, that is, they were sighted in certain areas significantly more often than would have been expected by chance. The proportion of such individuals varied between flocks from 35 to 65%. Overall, birds spent more time on the slatted area than would have been expected from the area that it occupied. 4. A wide variety of different behaviour patterns was observed both on litter and on slats, but with foraging occurring more on litter and feeding more on slats. 5. Movement appeared to be constrained by crowding, because time spent in locomotion decreased in approximately linear fashion with increased stocking density. This provides support for MAFF recommendations of limits on stocking density in deep litter houses.  相似文献

苗期夜温对番茄畸形果发生的影响   总被引：15，自引：1，他引：14  

李天来  王平  须晖  郭泳  孙国娟  陈伟之 《中国蔬菜》1997,1(2):1-0

试验表明番茄苗期低夜温不仅提高了畸形果发生率，而且也提高了畸形果平均级数和综合指数，并增加了畸形果的类型，同时乱形果在畸形果中所占的比例也增大。试验还认为：引起番茄畸形果大量发生的界限温度在大于６℃和小于１２℃的范围内，低温所需时间为幼苗２片子叶充分展开后１０～１６天，幼苗低温敏感期为２～４片真叶展开期。因此，番茄育苗期间应避免２～４片真叶展开期夜温低于１２℃。  相似文献
