18, 19 Other microbial agents reportedly associated with rosacea are Bacillus oleronius, Staphylococcus epidermidis, Helicobacter pylori, and Chlamydophila pneumoniae.
Perhaps most novel and interesting of these is the possibility of protective immunomodulatory influence from microbial diversity (suggested by the understudied 'biodiversity hypothesis') and other bioactive agents associated with biodiverse environments.
Early-life exposure to environmental microbial agents may be associated with the development of allergies.
Exposure to microbial agents in animal housing is associated with an increased prevalence of respiratory symptoms, including bronchial hyperresponsiveness, accelerated lung function decline, and neutrophil-mediated inflammation.
102 By definition, JIA is idiopathic with no identifiable cause; nevertheless, several microbial agents, particularly viruses, have been associated with the onset of JIA and suggested to initiate or augment this chronic disorder.
Second, we aimed to explore whether these selected home characteristics in addition to quantitatively measured exposure to the microbial agents in mattress dust are associated with current asthma symptoms and lung function in adults.
Exposure to high concentrations of bacterial endotoxin in the first months of life and dog ownership during the first two years of life, but not exposure to fungal microbial agents or home dampness, was associated with lower FeNO at school age.
However, exposure to increased levels of mold and other microbial agents has been implicated in diseases associated with damp indoor environments (Menzies and Kreiss 2006; Park et al. 2006).
Regarding indoor factors associated with higher indoor microbial agents levels, previous studies observed that early life exposure to indoor mould and dampness increases the risk of asthma [ 15- 17].
Exposure to microbial agents in a swine-confinement environment is associated with an increased prevalence of respiratory symptoms, including bronchial hyperresponsiveness (BHR), accelerated lung function decline, and neutrophil-mediated inflammation, 2, 4 without IgE-mediated sensitization against swine and food allergens.
