It is shown that an EHEC luxS mutant, unable to produce the bacterial autoinducer, still responds to a eukaryotic cell signal to activate expression of its virulence genes, implying a potential cross-communication between the luxS/AI-3 bacterial QS system and the epinephrine host signaling system.

Results establish that the conidia of S. atra contain trichothecene mycotoxins, and the inhalation of aerosols containing high concentrations of these conidia could be a potential hazard to health.
Characterization of Stachybotrys from water-damaged buildings based on morphology, growth, and metabolite production.
This study characterized and identified 122 Stachybotrys isolates, mainly from water-damaged buildings, by combining three different approaches: morphology, colony characteristics, and metabolite production, and shows that the three taxa/chemotypes should be treated separately.
Acute pulmonary hemorrhage in infants associated with exposure to Stachybotrys atra and other fungi.
Infants with pulmonary hemorrhage and hemosiderosis were more likely than controls to live in homes with toxigenic S atra and other fungi in the indoor air.
Building-associated pulmonary disease from exposure to Stachybotrys chartarum and Aspergillus versicolor.
This outbreak of disease associated with exposure to Stachybotrys chartarum and Aspergillus species represents a likely human response to inhaled fungal toxins in indoor environments and represents a public health issue currently inadequately addressed by building, health, or housing codes.
Apoptosis induction by the satratoxins and other trichothecene mycotoxins: relationship to ERK, p38 MAPK, and SAPK/JNK activation.

The results suggest that the satratoxins are among the most potent trichothecenes and that MAPKs may play integral roles in the diverse toxic manifestations of these mycotoxins.
Study of Toxin Production by Isolates of Stachybotrys chartarum and Memnoniella echinata Isolated during a Study of Pulmonary Hemosiderosis in Infants
Because of an interest in the possibility that trichothecene mycotoxins might be involved in this illness, a number of isolates of Stachybotrys chartarum were grown in the laboratory on rice and extracts were analyzed both for cytotoxicity and for specific toxins.
Health and immunology study following exposure to toxigenic fungi (Stachybotrys chartarum) in a water-damaged office environment.

It is concluded that prolonged and intense exposure to toxigenic S. chartarum and other atypical fungi was associated with reported disorders of the respiratory and central nervous systems, reported Disorders of the mucous membranes and a few parameters pertaining to the cellular and humoral immune system, suggesting a possible immune competency dysfunction.
Molecular and phenotypic descriptions of Stachybotrys chlorohalonata sp. nov. and two chemotypes of Stachybotrys chartarum found in water-damaged buildings.

The results show that S. chartarum sensu lato can be segregated into two chemotypes and one new species, S. chlorohalonata, which differs morphologically from S.chartarum by having smooth conidia, being more restricted in growth and producing a green extracellular pigment on the medium CYA.
