bacteria play an important role in the initiation and progression of diseases (not only in disease but affect health status of individual). populations of digestive microflora in chicken gut change with age and also affected by diet, stressors, and performance enhancers as well as in disease conditions. the aim of the pre-sent study was to know bacterial makeup in chicken gut, using denaturing ...

the intestinal bacterial diversity of stichopus japonicus was investigated using 16s ribosomal rna gene (rdna) clone library and polymerase chain reaction/denaturing gradient gel electrophoresis (pcr-dgge). the clone library yielded a total of 188 clones, and these were sequenced and classified into 106 operational taxonomic units (otus) with sequence similarity ranging from 88 to 100%. the cov...

agricultural sustainability is closely related with the efficient use of natural resources, which are primarily transformed by the action of microorganisms. soil microorganisms are usually used as early indicators of soil quality since they rapidly respond to changes in soil management. a field experiment was carried out aiming to evaluate the effect of siratro (macroptylium atropurpureum), bah...

Dryland ecosystems cover more than 30% of the terrestrial area of China, while processes that shape the biogeographic patterns of bacterial and fungal β-diversity have rarely been evaluated synchronously. To compare the biogeographic patterns and its drivers of bacterial and fungal β-diversity, we collected 62 soil samples from a typical dryland region of northwest China. We assessed bacterial ...

Plant species, plant community diversity and microbial interactions can significantly impact soil microbial communities, yet there are few data on the interactive effects of plant species and plant community diversity on soil bacterial communities. We hypothesized that plant species and plant community diversity affect soil bacterial communities by setting the context in which bacterial interac...

Productivity and predation are thought to be crucial drivers of bacterial diversity. We tested how the productivity-diversity of a natural bacterial community is modified by the presence of protist predators with different feeding preferences. In the absence of predators, there was a unimodal relationship between bacterial diversity and productivity. We found that three protist species (Bodo, S...

Mud volcanoes are taken into consideration by geologists and oil industry experts have given their association with oil and gas reserves and methane greenhouse gas production in hydrosphere and atmosphere. Gomishan mud volcano phenomenon in the southeastern edge of the Caspian Sea, given its oil and gas resources, has been studied by some geologists in terms of geology and tectonics but not in ...

to investigation of pathogenisity and genotype diversity of xanthomonas oryzae pv. oryzae (xoo) caused rice bacterial blight, several samples were collected from paddy field of rice in rasht-sangar, soumeh sara, rezvan shahr, daboudasht amol and rice-institute-research guilan during the summer of 2012, from plants that showed blight and yellowing in their leaves. bacterial isolates were identif...
