Hypokalaemic episodic polymyopathy in cats fed a vegetarian diet     

A. LEON  SAF BAIN  WR LEVICK 《Australian veterinary journal》1992,69(10):249-254

A previously undocumented hypokalaemic condition with a cyclical nature, comprising acute bouts of polymyopathy followed by spontaneous recoveries, is described in the cat. Cats being fed a high protein vegetarian diet developed recurrent episodes of polymyopathy, characterised by ventroflexion of the head and neck, stiff forelimb gait, lateral head-resting and generalised muscle weakness. Plasma potassium concentrations (mean +/- standard deviation) were reduced from 3.28 +/- 0.33 mmol/l at the beginning of the experiment to 2.45 +/- 0.24 mmol/l during bouts of myopathy. This hypokalaemia was associated with increased creatine kinase activities indicative of muscle damage, and decreased urinary potassium concentrations, and was caused by insufficient dietary potassium. Cats that received the same diet supplemented with potassium did not develop hypokalaemic polymyopathy. Spontaneous recoveries of affected cats were not associated consistently with increases in plasma potassium concentrations. Plasma taurine concentrations decreased and glutamic acid increased markedly in all cats fed the experimental diet. There was no evidence of thiamin deficiency associated with the high glutamic acid intake. Veterinarians should be aware that hypokalaemic cats, and in particular those on potassium-deficient diets, may show cyclical disease with episodes of polymyopathy recurring after periods of spontaneous clinical recovery. This condition in cats may be a useful animal model for familial hypokalaemic periodic paralysis in humans.  相似文献   

Root rot of cabbage caused by Phytophthora drechsleri     

A. H. THOMPSON  A. J. L. PHILLIPS 《Plant pathology》1988,37(2):297-299

A root rot of cabbage is reported from South Africa. The causal pathogen was identified as Phytophthora drechsleri , based on morphological characters and electrophoretic patterns of soluble proteins.  相似文献   

Cross reactions of an antiserum to plum pox potyvirus1     

D. JAMES  D. A. THOMPSON  S. E. GODKIN 《EPPO Bulletin》1994,24(3):605-614

In the early spring of 1992, plum pox-like viruses (PPLVs) were detected by standard ELISA in some Prunus species. The isolates reacted positively with plum pox potyvirus (PPV) antisera in immunosorbent electron microscopy and Western blot analysis. In Western blot analyses, bands associated with the coat protein subunits of the PPLVs were 48–56 kDa, whereas bands associated with the coat protein subunits of known PPV isolates were 32–37 kDa in size. Also, the PPLVs differed from known PPV isolates in their symptoms on woody and herbaceous indicators, and in their herbaceous host range. None of these PPLVs appears to be an isolate of PPV.  相似文献

Variations in composition of pasture herbage     

J. K. THOMPSON  R. W. WARREN 《Grass and Forage Science》1979,34(2):83-88

Changes in the chemical composition of pasture samples from five dairy farms were observed over a 2-year period. Many of the minerals were at their lowest concentration in samples taken in the spring and early summer. At these times the concentrations of P, Mg and Na were often less than sufficient to meet the calculated requirements of the dairy cow fed on pasture alone. Cu and Co concentrations in the herbage were also generally low relative to the needs of the dairy cow.  相似文献   

Efficacy of avermectin B₁ given orally against equine intestinal strongyles and Onchocera microfilaria     

TD MOGG †  CC POLLITT  JP WILLMORE  H. THOMPSON ‡ 《Australian veterinary journal》1990,67(11):399-401

Three groups of horses and ponies (N = 13, 13 and 12) were treated with ivermectin paste (0.2 mg/kg p.o.), avermectin B1 solution (0.2 mg/kg p.o.), or fenbendazole suspension (10 mg/kg via nasogastric tube). The avermectin B1 was a 1% solution in a propylene glycolglycerol formal base. Faecal strongyle egg counts were performed before, and 14, 28, 42, 56 and 70 d, after treatment. Full-thickness skin biopsies from the neck, pectoral and umbilical regions were examined for Onchocera microfilaria before treatment, and again 14 and 70 d later. Ivermectin therapy produced a significant (P less than 0.01) decrease in mean strongyle egg counts 14, 28, 42 and 56 d after treatment. Avermectin B1 therapy resulted in significant (P less than 0.01) decreases in mean strongyle egg counts 14, 28 and 42 d after treatment. All horses given ivermectin or avermectin B1 had zero strongyle egg counts 14 and 28 d after treatment. Fenbendazole failed to significantly decrease strongyle egg counts. Both ivermectin and avermectin B1 resulted in zero microfilaria counts in all horses 14 d after treatment. On day 70 the percentage decrease in microfilaria counts were 100% and 99.6% respectively. Fenbendazole failed to significantly decrease microfilaria counts. The oral administration of this formulation of avermectin B1 appeared to be highly efficacious against intestinal strongyles and Onchocera microfilaria. The duration of anti-strongyle activity was, however, significantly (P less than 0.01) shorter than that of ivermectin paste.  相似文献
