Profiling bacterial community in upper respiratory tracts

Profiling bacterial community in upper respiratory tracts

BACKGROUND Infection by pathogenic viruses results in rapid epithelial damage and significantly impacts on the condition of the upper respiratory tract, thus the effects of viral infection may induce changes in microbiota. Thus, we aimed to define the healthy microbiota and the viral pathogen-affected microbiota in the upper respiratory tract. In addition, any association between the type of vi...

Assessing Bacterial Populations in the Lung by Replicate Analysis of Samples from the Upper and Lower Respiratory Tracts

Microbes of the human respiratory tract are important in health and disease, but accurate sampling of the lung presents challenges. Lung microbes are commonly sampled by bronchoscopy, but to acquire samples the bronchoscope must pass through the upper respiratory tract, which is rich in microbes. Here we present methods to identify authentic lung microbiota in bronchoalveolar lavage (BAL) fluid...

Fungal Diseases of the Respiratory Tracts-Section 4

Fusarium spp., have been recognized during the past decade to cause disseminated infection, particularly in granulocytopenic patients undergoing intensive antileukemic chemotherapy or bone marrow transplantation. The lung, sinuses, and skin are the primary portals of entry. The periungual regions of the toes notably may be a particularly important site of initial invasion. Invasive Fusarium inf...
