Rationale for concerns regarding Stachybotrys . It is only recently that the idea that Stachybotrys can cause significant disease has risen to national prominence ( 137 ), although the documented pulmonary effects of exposure to some fungal species date to the 18th century. The transient acute upper respiratory symptoms in workers exposed to contaminated materials during the equine Stachybotrys outbreak ( 312 ), as well as anecdotal reports ( 11 , 423 ), suggested that this fungus could exert at least minor pulmonary effects. Concerns in the United States regarding Stachybotrys developed primarily due to reports linking an unusual cluster of pediatric IPH and mold exposure in the Cleveland area ( 65 , 123 , 278 ). Coincidentally, S. chartarum, and in some cases its mycotoxins, was isolated in building materials and air samples in buildings associated with moisture problems and complaints of SBS-like illnesses ( 41 , 79 , 164 , 168 , 267 ; E.
I heard about "toxic molds" that grow in homes and other buildings. Should I be concerned about a serious health risk to me and my family? The term "toxic mold" is not accurate. While certain molds are toxigenic, meaning they can produce toxins (specifically mycotoxins), the molds themselves are not toxic, or poisonous. Hazards presented by molds that may produce mycotoxins should be considered the same as other common molds which can grow in your house. There is always a little mold everywhere - in the air and on many surfaces.
Stachybotrys chartarum , also called Stachybotrys atra , Stachybotrys alternans or Stilbospora chartarum , is a black mold that produces its conidia in slime heads. It is sometimes found in soil and grain, but the mold is most often detected in cellulose -rich building materials from damp or water-damaged buildings. [ 1 ] S. chartarum was originally described from the wall of a house in Prague in 1837 by Czech mycologist August Carl Joseph Corda . It requires high moisture content in order to grow and is associated with wet gypsum material and wallpaper. [ 2 ]
L’International Mycological Association (Association internationale de mycologie) répertorie, dans sa banque de données fongiques, 87 espèces nommées faisant partie du genre Stachybotrys {3971}. Par ailleurs, il y a quinze espèces nommées de Stachybotrys inscrites dans la banque de données internationale du consortium Universal Protein Resource (UniProt) et plus de dix souches non nommées {3318}. C’est de fait le S. chartarum qui fait l’objet de multiples études scientifiques et d’articles profanes à cause de son rôle potentiel dans les problèmes de santé associés à la mauvaise qualité de l’air des édifices contaminés par des moisissures ou des édifices dits « malsains ». Ces problèmes de santé seraient attribuables aux puissantes mycotoxines produites par certaines souches de S. chartarum. Taxonomie L’espèce type est le Stachybotrys chartarum ( Stachybotrys atra Corda).
