This study aimed to examine the effect of probiotics containing Bacillus subtilis and oregano essential oil on growth performance, intestinal morphology, cecal microbial composition in pullets aged 0–18 weeks. A total 324 day-old Hy-Line Brown chicks were randomly assigned three treatment groups, with six replicates per group 18 birds pen. The experimental treatments consisted following: a cont...
The bacterial community of rhizosphere soil maintains properties, regulates the microbiome, improves productivity, and sustains agriculture. However, structure function communities have been interrupted or destroyed by unreasonable agricultural practices, especially excessive use chemical fertilizers. Microbial inoculants, regarded as harmless, effective, environmentally friendly amendments, ar...
Although culture-independent techniques have refuted lung sterility in health, controversy about contamination during bronchoscope passage through the upper respiratory tract (URT) has impeded research progress. We sought to establish whether bronchoscopic sampling accurately reflects the lung microbiome in health and to distinguish between two proposed routes of authentic microbial immigration...
the present study aimed to assess pure planted species (i.e., alnus subcordata l., poplus deltoids l., taxadium distichum l. rich) and a mixed natural forest (i.e., dominated by quercus castaneifolia c. a. mey. - carpinus betulus l. - parrotia persica c. a. meyer) on basis of some soil quality indices in mazandaran province, northern iran. sixteen samples per stand were taken from the top 10 cm...
Cystic fibrosis (CF) is a genetic disease resulting in chronic polymicrobial infections of the airways and progressive decline in lung function. To gain insight into the underlying causes of severe lung diseases, we aimed at comparing the airway microbiota detected in sputum of CF patients with stable lung function (S) versus those with a substantial decline in lung function (SD). Microbiota co...
