One of more lobes of the lung may be affected, with the infection being very localized to these areas. Most cases are infectious and frequently arises as a secondary bacterial infection following a viral respiratory infection like influenza. Bronchopneumonia Affects the terminal parts of the airways ...
A range of host defence mechanisms exists to protect the lung from infection. These defence mechanisms include physical defences such as the filtration of air and the mucociliary escalator as well as the innate immune mechanisms such as the alveolar macrophage. The activity of these cells is ...
They belong to Enterovirus genus and family Piconaviridae. The three species of rhinovirus include around 160 recognised types of human rhinovirus that differ according to their surface proteins (serotypes). The infection is spread through two modes: respiratory droplets and from fomites. ...

(Supplementary Fig.2a, b). The effects of pathogenic microorganisms during acute and chronic infections on hosts or tumors are remarkably different. To determine whether acute bacterial infection has the same effects on promoting tumor cell metastasis, we constructed an acute pulmonary infection mouse ...
Here we found that bacterial taxa chronically infecting a patient were both persistent and common, whereas intermittent taxa were typically infrequent and rare. Or rather, the chronic and intermittent colonizing taxa respectively represent the resident and transient portions of the wider lung infection ...
Bacterial infection stimulates an intense neutrophilic response which fails to eradicate the infection leading to sustained release of pro-inflammatory mediators, continuous influx of inflammatory cells and bacteria persistence [2]. Despite advances in our understanding of the molecular and cellular basis ...
Thus, Tregs deploying a mecha- nism normally associated with elimination of virus-infected cells are key effectors responsible for immune regulation in the lung during acute viral infection. RESULTS Loss of Tregs increases T-cell-driven lung inflammation and RSV disease severity Bacterial artificial ...
Symptoms depend on whether the abscess is caused by anaerobic or other bacterial infection. A lung abscess may be asymptomatic in a small proportion of patients in the early stages. Typical symptoms are below. Anaerobic infection in lung abscess Patients often present with indolent symptoms that evo...
