Investigation on the clinical efficacy and safety of meloxicam (Metacam) in the treatment of non-infectious locomotor disorders in pigs     

Friton GM  Philipp H  Schneider T  Kleemann R 《Berliner und Münchener tier?rztliche Wochenschrift》2003,116(9-10):421-426

The clinical efficacy and safety of meloxicam (Metacam 20 mg/ml) in the treatment of non-infectious locomotor disorders in pigs was investigated in a randomised double-blind, placebo controlled, multi-centre field study. A total of 220 pigs were examined, 211 pigs were suitable for evaluation. Treatment was performed on Day 1 with meloxicam (0.4 mg meloxicam/kg) or placebo by intramuscular injection. If necessary, treatment was optionally repeated on Day 2. Clinical examinations were conducted daily from Day 1 (immediately prior to initiation of therapy) to Day 4. The primary parameter, mean "Clinical Lameness Score" (CLS, a sum of the scores of "Lameness at Rest" and "Lameness at Walk"; range 2 to 11) improved from 6.8 and 6.3 on Day 1, to 3.5 and 4.7 on Day 4 in the meloxicam and placebo groups respectively (p < 0.001). At the final examination mean changes from baseline for CLS (Day 1) were 3.25 for meloxicam treated animals and 1.7 for placebo treated animals (p < 0.001). Behaviour score and feed intake improved during the study period with statistically significant differences in favour of meloxicam at all time points after initiation of therapy. Significantly fewer pigs received a second treatment in the meloxicam group than in the placebo group, 46% versus 73% (p < 0.001). A 'very good' or 'good' clinical efficacy assessment was recorded in 83% of the meloxicam cases compared to 42% of the placebo controls at the final examination (p < 0.001). No adverse events were reported due to the use of meloxicam. Furthermore safety of meloxicam in pregnant sows was demonstrated. It is concluded that intramuscular injection of meloxicam (Metacam) at a dosage of 0.4 mg/kg is efficacious and safe for the treatment of non-infectious locomotor disorders in pigs.  相似文献

The Effect of Probiotics in a Litopenaeus vannamei Biofloc Culture System Infected with Vibrio parahaemolyticus     

Dariano Krummenauer  Luis Poersch  Luiz A. Romano  Gabriele R. Lara  Pedro Encarnação 《Journal Of Applied Aquaculture》2013,25(4):370-379

We analyzed the effect of commercial bacterial probiotics on a Litopenaeus vannamei biofloc culture system infected with Vibrio parahaemolyticus. Three replicates of two experimental treatments were conducted: a control system (without probiotic) and a system with the application of a multistrain probiotic containing Bacillus spp., Enterococcus spp., Thiobacillus spp., and Paracoccus spp. applied to the water and another multistrain probiotic containing Bacillus spp., Enterococcus spp., and Lactobacillus spp. added to the feed. Growth and survival rate were significantly higher in the probiotic treatment group (P < 0.05), and the shrimp in the probiotic group also had a lower (P < 0.05) FCR compared to the shrimp in the control group (1.4 vs. 2.7).  相似文献   

Induction of systemic resistance,root colonisation and biocontrol activities of the rhizospheric strain of <Emphasis Type="Italic">Serratia plymuthica</Emphasis> are dependent on N-acyl homoserine lactones     

Yandong Pang  Xiaoguang Liu  Yingxin Ma  Leonid Chernin  Gabriele Berg  Kexiang Gao 《European journal of plant pathology / European Foundation for Plant Pathology》2009,124(2):261-268

Quorum sensing regulation, mediated by N-acyl homoserine lactone signals, produced by strain Serratia plymuthica HRO-C48 isolated from the rhizosphere of oilseed rape, was found to be responsible for this strain’s ability to produce the broad spectrum antibiotic pyrrolnitrin. In this study, we have shown that some other biocontrol-related traits of strain HRO-C48, such as protection of cucumbers against Pythium apahnidermatum damping-off disease, induced systemic resistance to Botrytis cinerea grey mold in bean and tomato plants, and that colonisation of the rhizosphere also depends on AHL signalling. The results prove that quorum sensing regulation may be generally involved in interactions between plant-associated bacteria, fungal pathogens and host plants.  相似文献

Soil structure of arable and non‐arable land in the Western Siberian Grain Belt in Russia—Application of the soil fingerprint code for topsoil characterization          下载免费PDF全文

Soil structure is a key indicator for soil quality. Often, a degradation of the soil structure is the result of inappropriate land management. This investigation was carried out in the Western Siberian forest steppe, because soil degradation is an important issue in this part of the Siberian Grain Belt. Therefore, soil structure and further soil properties were examined in the vicinity of the city of Tyumen, Russia. Arable and non‐arable sites were compared by means of the soil fingerprint code (SFC). With SFC the soil surface conditions, chemical and physical parameters of the topsoil were recorded and evaluated in two depths: 0–5 cm and 5–30 cm. The suitability of the SFC to quantify changes of the soil structure of the topsoil was tested. The SFCs of arable and non‐arable sites show that soil structure deteriorates due to arable use. The percentage of granular aggregates decreases and the percentage of subangular blocky and angular blocky aggregates increases. Furthermore, ploughing leads to strong clod formation. Differences in soil structure between 0–5 cm and 5–30 cm soil depth were smaller at arable sites in comparison to non‐arable sites. It was ascertained the SFC is suitable to quantify changes of the soil structure.  相似文献   

Untersuchungen zur Verticillium-Welke im Hopfenanbaugebiet Hallertau     

Katja A. Maurer  Gabriele Berg  Stefan Seefelder 《Gesunde Pflanzen》2014,66(2):53-61

Verticillium wilt is a devastating disease in hops and causes considerable crop losses. V. albo-atrum is the most widespread species, whereas V. dahliae is rarely found. Due to the survival of the fungus for several years in soil by resting structures and the lack of effective chemical control, a fast detection method is needed. One aim of this study was to evaluate the occurrence of Verticillium spp. in the Hallertau region (Germany). Therefore, 76 hop plants, with or without wilt symptoms, were analyzed using a real time PCR (polymerase chain reaction) assay. V. albo-atrum was identified in 57 bine samples. The pathogen can sporadically appear without showing visual symptoms. The abundance of the fungus inside the plants was analyzed. Furthermore, four beneficial bacteria, Burkholderia terricola ZR2-12, Pseudomonas poae RE*1-1-14, Serratia plymuthica 3Re4-18, and Stenotrophomonas rhizophila DSM14405^T, were evaluated as biological control agents in hops. The colonization competence in the root system, plant growing promotion, and antagonistic effects were assessed. All strains colonized the endorhiza and the rhizosphere. The bacterial strains B. terricola ZR2-12, S. plymuthica 3Re4-18, and S. rhizophila DSM14405^T are promising candidates for further biocontrol strategies. Thus, first steps towards the biological control of Verticillium wilt were presented.  相似文献   

Time-dependent alterations in gene expression of interleukin-8 in the bronchial epithelium of horses with recurrent airway obstruction     

Ainsworth DM  Wagner B  Franchini M  Grünig G  Erb HN  Tan JY 《American journal of veterinary research》2006,67(4):669-677

OBJECTIVE: To evaluate time-dependent alterations in gene expression of chemokines in bronchial epithelium of recurrent airway obstruction (RAO)-affected horses and whether alterations resulted from increases in gene expression of interleukin (IL)-17 in cells isolated from bronchoalveolar lavage fluid (BALF). ANIMALS: 8 RAO-susceptible horses and 9 control horses. PROCEDURE: In 2 experiments, both groups of horses were evaluated after being maintained on pasture and after being stabled and fed dusty hay for 1, 14, 35, and 49 days (experiment 1) or 14 and 28 days (experiment 2). In experiment 1, gene expression of IL-8, chemokine (C-X-C motif) ligand 1 (CXCL1), granulocyte-macrophage colony-stimulating factor (GM-CSF), granulocyte colony-stimulating factor (G-CSF), and Toll-like receptor 4 (TLR4) in epithelium and IL-8, IL-17, and TLR4 in BALF cells was measured. In experiment 2, bronchial biopsy specimens were evaluated for IL-8 immunoreactivity. RESULTS: In RAO-susceptible horses after 14 days of challenge exposure, there was a 3- and 10-fold increase in gene expression of IL-8 for epithelial and BALF cells and an increase in IL-8 immunoreactivity in epithelial cells. Challenge exposure failed to alter gene expression of CXCL1, GM-CSF, G-CSF, and TLR4 in epithelial cells of any horses at any time point. During challenge exposure, gene expression of BALF cell IL-17 was downregulated in control horses (day 1) and upregulated in RAO-affected horses (day 35). CONCLUSIONS AND CLINICAL RELEVANCE: Epithelial-derived IL-8 may promote airway neutrophilia, but the inciting stimulus is unlikely to be IL-17 because upregulation of this gene is subsequent to that of IL-8 in epithelial cells.  相似文献   

<Emphasis Type="Italic">Cornus mas</Emphasis> (L.) Fruit as a Potential Source of Natural Health-Promoting Compounds: Physico-Chemical Characterisation of Bioactive Components     

Marta De Biaggi  Dario Donno  Maria Gabriella Mellano  Isidoro Riondato  Ernest N. Rakotoniaina  Gabriele L. Beccaro 《Plant foods for human nutrition (Dordrecht, Netherlands)》2018,73(2):89-94

Interest in new sources of anti-inflammatory and antioxidant compounds has recently become a major research issue, with the cornelian cherry (Cornus mas L.) receiving particular attention for its significant amounts of phenolic compounds and vitamins, which exhibit a wide range of biological and pharmacological properties. This study was aimed at increasing knowledge regarding the cornelian cherry in Italy through the analysis of biologically active substances in the locally available genotype “Chieri”. Spectrophotometric methods were applied to evaluate antioxidant activity, total anthocyanin content and total polyphenolic content. Identification and quantification of the main phytochemical compounds (polyphenols, monoterpenes, organic acids and vitamin C) was performed via high performance liquid chromatography coupled to a diode array detector. C. mas extracts showed high levels of total soluble solids and low acidity. High amounts of phenolic secondary metabolites were observed, with particular reference to anthocyanins (134.71 mg_C3G/100 g_FW), which confer remarkable nutraceutical properties to the analysed samples. These results highlight the potential of C. mas fruits as a good source of natural antioxidants, suggesting their use as a functional food. Future studies should focus on identifying other specific phytochemical compounds and the genetic traits of local varieties in order to improve cornelian cherry cultivars for food and medicine production.  相似文献
