Cryptic species in Stachybotrys chartarum.
Stachybotrys chartarum has received much attention as a possible cause of sick-building syndrome. Because morphological species recognition in fungi can hide diversity, we applied a phylogenetic approach to search for cryptic species. We examined 23 isolates from the San Francisco Bay Area, and another seven from around the US. Using markers we developed for three polymorphic protein coding loc...
متن کاملThe Pathogenicity of Stachybotrys chartarum.
Stachybotrys chartarum is a dematiaceous fungus that is ubiquitous in our living environment. This fungus has long been regarded as non-pathogenic and its inhalation effect on humans has been scarcely studied. Recently, however, epidemiologic studies on acute idiopathic pulmonary hemorrhage in infants suggested that the fungus might be potentially pathogenic to humans. To determine the pathogen...
متن کاملStrain differences influence murine pulmonary responses to Stachybotrys chartarum.
When the fungus Stachybotrys chartarum is inhaled, its mycotoxins may cause lung injury and inflammation. The severity of human responses to S. chartarum in both occupational and home settings varies widely. To explore these differences, we intratracheally instilled C3H/HeJ, BALB/c, and C57BL/6J mice with S. chartarum spores suspended in saline. One day later, the mice were humanely killed, bro...
متن کاملTHE EFFECTS OF CAPTOPRIL ON PULMONARY AND SYS TEMIC ARTERIAL PRESSURES IN HIGHALTITUDE PULMONARY HYPERTENSION
The purpose of this investigation was to assess the effect of captopril on both systemic (P.a) and pulmonary arterial pressures (PPA) in patients with high-altitude pulmonary hypertension (HAPH). Seventeen patients (mean age 44±6.8 years) with HAPH and mild to moderate systemic arterial hypertension were included in the study. All patients underwent right heart catheterization with measurem...
متن کاملIloprost inhalation solution for the treatment of pulmonary arterial hypertension.
Pulmonary arterial hypertension (PAH) is a condition that is characterised by increased pulmonary arterial pressure and vascular resistance that can lead to right ventricular failure and death. A variety of disturbances in pulmonary vascular endothelial and smooth muscle function are present in PAH, including reduced production of vasodilator and antiproliferative substances, such as nitric oxi...
