Animal skin acts as the barrier against invasion by pathogens and microbial colonizers. Environmental microbiota plays a significant role in shaping these microbial communities, which, in turn, have profound implications for host health. Previous research has focused on characterizing microorganisms on bats' skin and in their roosting environments, particularly bacterial communities.

Background: Uncontrolled severe eosinophilic chronic rhinosinusitis (eCRS) is associated with elevated levels of Th2 cells and raised immunoglobulin concentrations in nasal polyp tissue. eCRS is characterized by high eosinophilic infiltration and type 2 inflammation. Gαi1/3 proteins participate in allergic inflammation by regulating immune cells.

Background: Lungs of people with Cystic Fibrosis (pwCF) are characterized by chronic inflammation and infection with P. aeruginosa. High levels of IL-17 A and F have been observed in sputum of pwCF and the interleukin-17(IL-17) family (A-to-F) has been suggested to play a key role in CF pulmonary disease.

We hypothesized that bighorn sheep ewes with chronic nasal carriage are the source of infection that results in fatal lamb pneumonia. We tested this hypothesis in captive bighorn ewes at two study facilities over a 5-year period, by identifying carrier ewes and then comparing lamb fates in groups that did (exposed pens) or did not (non-exposed pens) include one or more carrier ewes. Most (23 of 30) lambs born in exposed pens, but none of 11 lambs born in non-exposed pens, contracted fatal pneumonia.

Background and aim Etiopathogeneses of chronic rhinosinusitis are poorly understood. Recent research emphasizes culture-independent molecular sequencing to identify clusters of flora that may function as drivers of inflammation. Studies also indicate that macrolides are as effective as corticosteroids in controlling chronic rhinosinusitis.
