Physiologic races ofFusarium oxysporum f.sp.melonis in the southeastern anatolia region of turkey and varietal reactions to races of the pathogen

Thirty-four isolates ofFusarium oxysporum f.sp.melonis (F.o.m.) obtained from 205 fields in melon-producing areas in the southeastern Anatolia Region of Turkey were identified on the basis of colony morphology and pathogenicity by the root dip method. In this region the mean prevalence of wilt disease was 88.1% and the mean incidence of disease was 47.5%. Physiologic races 0, 1, 2, and 1,2 of the pathogen were determined by their reactions on differential melon cultivars ‘Charentais T,’ ‘Isoblon’, ‘Isovac’ and ‘Margot’ in the greenhouse. Race 1,2, representating 58.8% (20/34) of all isolates, was widely distributed. Of the other pathogenic isolates, eight were identified as race 0, five as race 1, and one as race 2. This is the first report of physiologic races ofF.o.m. in Turkey. Of 44 melon cultivars tested in the greenhouse for resistance toF.o.m. races, 36 were found to be moderately resistant to race 0, 17 were susceptible to race 1,2, 34.1% were highly resistant to race 1, and 52.2% had moderate resistance to race 2. http://www.phytoparasitica.org posting July 16, 2002.

The relationship between fermentation and the morphological structure of rumen epithelium in sheep fed pelleted feeds]

Wethers were fed complete granular feed rations including 41.81% of grass hay, 25.28% of barley, 15.37% of sawdust, 14.98% of molasses, 1.32% of urea, and 1.24% of mineral supplement in dry matter for 24 weeks. Samples of the dorsal rumen sac of these wethers were subjected to patho-anatomical, histological, histo-chemical, and electron-microscopical examination. Volatile fatty acids were also determined in the rumen fluid of slaughtered animals. The control group was given the same diet in the classical form with long hay. The rumen contents of the slaughtered animals of the experimental group had an increased level of total volatile fatty acids (125.93 mM) and butyric acid (17.8 M%). The acetate:propionate ratio was 3.66. No substantial differences were observed in enzymatic activity. Electronograms recorded an increase in the number of T cells and keratinizing cells -- this suggests an increased intensity of the process of keratinization.     

Reduction and stabilization of hip luxation by the transposition of the ligamentum sacrotuberale in dogs: an in vivo study

OBJECTIVES: To evaluate the effectiveness of transposition of the sacrotuberous ligament (LST) for the treatment of coxofemoral luxation in the dog. STUDY DESIGN: In vivo experimental study. SAMPLE POPULATION: Ten mixed-breed dogs (weighing 12 to 26 kg). METHODS: After general anesthesia, the LST was exposed and released from the sacrum with a sacral bone fragment. Coxofemoral luxation was created by capsulotomy and transection of the ligament of the head of the femur. Suture was passed through 2 small holes in the bone fragment to guide transposition of the LST through a tunnel drilled through the acetabulum and femoral head and neck. The suture material was pulled tight and an interference screw was placed into the femoral tunnel to lock the sacral bone fragment and LST securely in the tunnel. Butorphanol was administered for pain relief and dogs were allowed unrestricted activity. Coxofemoral radiographs were obtained at 15-day intervals. Two dogs were euthanatized for macroscopic and histopathologic examinations at 3 months. RESULTS: Release of the sacral bone was moderately difficult. The transposed ligament and bone fragment were of an appropriate length and were easily and securely fixed by a interference screw method. Visible severe lameness, during the first 7 to 10 days improved to mild lameness within 10 to 21 days. Gait was subjectively normal after 5 weeks. No radiographic abnormalities were observed at any time point. Grossly, the LST was intact and apparently viable and functional. On histopathology, the space in the bone tunnel was filled with new tissue and a hyaline-like layer surrounded the LST. The sacral bone fragment attached to the LST was united with the femoral bone. CONCLUSIONS: Transposition of the LST reduced and stabilized experimentally induced coxofemoral luxation in 10 dogs. Survival of the LST up to 3 months and its adaptation to transposition suggest that this surgical technique could be considered as a permanent treatment option for hip luxations. Transposition and fixation of the LST was easy, but releasing the sacral edge of the LST was difficult because of its deep location and division of the origin into 2 branches in some dogs. CLINICAL RELEVANCE: Results of this experimental study suggest that the technique may be satisfactorily used in dogs with coxofemoral luxation.     

Transposition of the sacrotuberous ligament for the treatment of coxofemoral luxation in dogs

A surgical technique is described for transposition of the sacrotuberous ligament to replace the teres ligament in the treatment of coxofemoral luxation in dogs. Ten dogs with coxofemoral luxation were treated using this technique and all animals regained full limb function within two months of surgery. It is suggested that the technique could be employed in dogs suffering from all types of hip luxations.     

Rate of passage of a non-traditional diet through the digestive tract in sheep

The rate of passage of experimental diets based on non-conventional feeds through the alimentary tract of rams was studied. The composition of diets was as follows: barley straw (D-2, D-1), conditioned beech sawdust (D-2, D-1), waste cellulose fibre (D-2, D-1), lactosylureide (D-2), peanut waste (D-2), urea (D-1), wood molasses (D-2, D-1) and mineral supplement (D-2, W-1). The control feed (K) contained straw, barley, beet molasses and mineral supplement. As a marker was used a single application (50 g) of polyethylene (PE), particle size 0.4 mm and specific weight 0.924, which formed 3.9, 3.5 and 4% of the diet dry matter. After 10 days the recovery of polyethylene amounting to 81.23% (D-2), 84.78% (D-1) and 86.6% (K) was established. The polyethylene losses occurred most probably at its administration in feed (10-12%), elapsing of polyethylene excreted after 10 days following the administration (0.5-1.5%) and by potential retention in rumen and large intestine. Maximal excretion of feces was observed during the second day after administration of the markered feed; after three days the excretion was as follows: group D-2-62%, group D-1-57% and control group 75.6%. A longer retention time in rumen at feeding D-2 and D-1 diets can be contributed to a high content of fibre in these diets. The digestibility of dry matter in diet D-2 amounted to 61.2%, i n diet D-1 to 62.3% and in control diet to 68.7%. Higher digestibility of feed is in accordance with its higher excreting. As shown by the results, the diets based on non-conventional feeds (secondary wood sources) lead to the prolongation of feed retention time in rumen and slow down the rate of passage through the alimentary tract.     

A Proposed Index for Assessment of Row-replacement Intercropping System

A new index has been proposed for assessing an intercropping system where the component crops are in row replacement senes. It determines the Actual Yield Loss or gain (AYL) in respect to a component crop in an intercropping situation Here the sown proportion of the component crops with regard to its sole one is to be considered. This index appears to be more appropriate than other established indices like land equivalent ratio, relative yield loss, etc., particularly when per plant yield is considered. Partial AYLs (which are the two components of this index) can be considered as indicators regarding the competition existing between the component intercrops.     

Comparative therapeutic efficacy and safety of type-II collagen (UC-II), glucosamine and chondroitin in arthritic dogs: pain evaluation by ground force plate

The investigation was conducted on client-owned moderately arthritic dogs with two objectives: (i) to evaluate therapeutic efficacy of type-II collagen (UC-II) alone or in combination with glucosamine hydrochloride (GLU) and chondroitin sulphate (CHO), and (ii) to determine their tolerability and safety. Dogs in four groups (n = 7-10), were treated daily for a period of 150 days with placebo (Group-I), 10 mg active UC-II (Group-II), 2000 mg GLU + 1600 mg CHO (Group-III), and UC-II + GLU + CHO (Group-IV). On a monthly basis, dogs were evaluated for observational pain (overall pain, pain upon limb manipulation, and pain after physical exertion) using different numeric scales. Pain level was also measured objectively using piezoelectric sensor-based GFP for peak vertical force and impulse area. Dogs were also examined every month for physical, hepatic (ALP, ALT and bilirubin) and renal (BUN and creatinine) functions. Based on observations, significant (p < 0.05) reduction in pain was noted in Group-II, III, and IV dogs. Using GFP, significant increases in peak vertical force (N/kg body wt) and impulse area (N s/kg body wt), indicative of a decrease in arthritis associated pain, were observed in Group-II dogs only. None of the dogs in any group showed changes in physical, hepatic or renal functions. In conclusion, based on GFP data, moderately arthritic dogs treated with UC-II (10 mg) showed a marked reduction in arthritic pain with maximum improvement by day 150. UC-II, GLU and CHO operate through different mechanisms of action, and were well tolerated over a period of 150 days.
