食用菌复合保水颗粒菌种生产工艺及其应用研究

运用微生物发酵技术，配合新型合成材料，研制出食用菌复合保水颗粒菌种。这类菌种可保持活力60d。这一工艺可用于糙皮侧耳、金针菇、灵芝、白灵菇、杏鲍菇、鸡腿蘑和鲍鱼菇等多种食用菌苗种的制作。栽培试验证明，此类菌种的菌丝生长速度、现蕾时间、生物学效率与常用的棉籽壳菌种相似。     

阿莫西林、舒巴坦联用对鸭实验性大肠杆菌病的疗效试验

用试管两倍稀释法测定了阿莫西林、阿莫西林与舒巴坦联合对大肠杆菌的体外抗菌活性,并观察阿莫西林与舒巴坦联合治疗耐阿莫西林大肠杆菌诱发的鸭大肠杆菌病的效果。结果表明:阿莫西林与舒巴坦联合对鸭大肠杆菌产酶菌株体外抗菌活性优于阿莫西林,表现为明显的体外协同作用。阿莫西林与舒巴坦联用治疗耐阿莫西林大肠杆菌诱发的鸭大肠杆菌病,按10mg/kg体重(以阿莫西林量计算)肌肉注射,阿莫西林与舒巴坦联用1∶1和2∶1的有效率、治愈率分别为92.5%、92.5%和85%、80%,均显著高于感染对照组、阿莫西林饮水组及阿莫西林肌肉注射组(P<0.01)。     

Amoxicillin—current use in swine medicine

Amoxicillin has become a major antimicrobial substance in pig medicine for the treatment and control of severe, systemic infections such as Streptococcus suis. The minimum inhibitory concentration 90% (MIC 90) is 0.06 μg amoxicillin/ml, and the proposed epidemiological cut‐off value (ECOFF) is 0.5 μg/ml, giving only 0.7% of isolates above the ECOFF or of reduced susceptibility. Clinical breakpoints have not been set for amoxicillin against porcine pathogens yet, hence the use of ECOFFs. It has also been successfully used for bacterial respiratory infections caused by Actinobacillus pleuropneumoniae and Pasteurella multocida. The ECOFF for amoxicillin against A. pleuropneumoniae is also 0.5 μg/ml demonstrating only a reduced susceptibility in 11.3% of isolates. Similarly, P. multocida had an ECOFF of 1.0 μg/ml and a reduced susceptibility in only 2.6% of isolates. This reduced susceptibility disappears when combined with the beta‐lactamase inhibitor, clavulanic acid, demonstrating that it is primarily associated with beta‐lactamase production. In contrast, amoxicillin is active against Escherichia coli and Salmonella species but using ECOFFs of 8.0 and 4.0 μg/ml, respectively, reduced susceptibility can be seen in 70.9% and 67.7% of isolates. These high levels of reduced susceptibility are primarily due to beta‐lactamase production also, and most of this resistance can be overcome by the combination of amoxicillin with clavulanic acid. Currently, amoxicillin alone is considered an extremely valuable antimicrobial in both human and animal medicine and remains in the critically important category of antibiotics alongside the fluoroquinolones and macrolides by the World Health Organization as well as the third‐ and fourth‐generation cephalosporins, but these cephalosporins show marked resistance to basic beta‐lactamase production and are only destroyed by the extended‐spectrum beta‐lactamases. Amoxicillin alone and in combination with clavulanic acid are currently classed together in Category 2 in the European Union. By reviewing the pharmacodynamic data and comparing this with pharmacokinetic data from healthy and infected animals and clinical trial data, it can be seen that the product has a good efficacy against S. suis and A. pleuropneumoniae, in spite of usage over many years. However, it may be much less efficacious on its own against E. coli, due to reduced susceptibility and resistance associated with beta‐lactamase production, which is largely overcome by the use of clavulanic acid. It is felt that this differentiation may be useful in future classification of amoxicillin alone, in comparison with its combined use with clavulanic acid and thereby preserve the use of the more critically important antibiotics in veterinary medicine and reducing the risk of their resistance being transmitted to human.     

有机生态栽培基质配比对生菜生长及品质的影响

以传统基质草炭、蛭石及腐熟羊粪和玉米秸秆为原料,配制成12种不同配比的栽培基质,以商品叶菜类栽培基质作为对照,研究不同基质配方对生菜生长的影响,以期获得最适合生菜栽培的基质配比组合。结果表明,不同组合基质配比均能满足生菜的正常生长,所有处理的株高、叶面积、单株鲜重和单株干重都较对照组(CK)有着不同程度提高,其中T11(草炭∶腐熟羊粪∶玉米秸秆∶蛭石=1∶4∶3∶4)条件下各指标表现最好,分别较CK提高了31.80%、47.15%、59.43%和79.53%;从生理生化指标来看,T11处理的Vc含量最高,是CK的2.5倍;T10(草炭∶腐熟羊粪∶玉米秸秆∶蛭石=3∶1∶4∶4)的根系活力是所有处理中最高的,达到CK的2.02倍;T12(草炭∶腐熟羊粪∶玉米秸秆∶蛭石=3∶4∶1∶4)处理的叶绿素含量最高,是CK的1.41倍,硝酸盐含量最低,较CK降幅达到74.59%。通过隶属函数进行综合比较分析,我们认为T11是所有供试处理中最适合生菜栽培的基质配比。     

东北“三大硬阔”叶片和叶轴质量分配比较

以3个树种健康复叶为试材,研究了叶内光合构件和支撑构件的生物量投资的种内种间变化规律。结果表明:水曲柳、胡桃楸和黄檗叶轴质量占复叶质量的比例分别为0.18、0.26和0.17,胡桃楸显著大于其它2个树种。跨物种尺度上,复叶大的树种需要更多的叶内支撑结构投资。但物种水平上,水曲柳叶片投资随叶增大而增大,胡桃楸则降低,黄檗基本稳定,表现出与跨物种水平上的叶片投资随叶增大而降低的普遍规律不同。今后需要加深物种水平上叶内生物量分配的异速生长的了解。
