“…The elevated levels of fungal aerosol in farmhouses compared to urban homes were also shown during Finnish studies [5,11,17]. In the study by Pasanen [11], the highest total culturable fungal spore counts were recorded in old rural houses (geometric mean 1012 CFU/m 3 . Moreover, the microbial contamination of indoor air was similar in farmhouses and in other rural buildings, suggesting a spread of microorganisms from agricultural sources to indoor environments [17].…”

The aim of this study was to characterize the microbial contamination of the air in farmhouses (defined as residential buildings on farms) on the basis of volumetric (using a six-stage Andersen impactor) measurements of bacterial and fungal aerosols. The microbial air quality (including both the total concentration of bioaerosols and their respirable fractions) in farmhouses was collated with the bacterial and fungal air contamination in urban dwellings. In comparison with the urban dwellings, the air in the farmhouses was characterized by significantly higher concentrations of culturable bacteria and fungi. However, respirable microorganisms in the farmhouses constituted the smaller fraction of all culturable bacteria and fungi. The results indicate that the microbial air quality in the farmhouses was most likely affected by the presence of farm buildings, which acted as additional bioaerosol emission sources. The smaller respirable bioaerosol fraction observed in the farmhouses could be explained by the indirect transfer of bacteria and fungi on workers' clothing and bodies from farm buildings to the habitable environments.

“…Many fungi pose health risks, causing not only frequent allergic diseases but also immunotoxic diseases such as sick building syndrome (Burch & Levetin, 2002). Indoor fungal spores are strongly linked to respiratory diseases (Stryjakowska-Sekulska et al, 2005) and there is considerable evidence to suggest that elevated spore counts inside buildings can prompt allergy symptoms (Peltola et al, 2001). Some of the genera isolated in this study such as Stachybotrys are widely associated with symptoms of ill health in exposed people (Salkinoja-Salonen et al, 2003) and biodeterioration of damp materials (Kasznica-Kocot et al, 2007).…”

“…Recently, a pumilacidin-producing B. pumilus has been implicated in a case of food poisoning (13). A study by Brophy and Knoop (9) reported experimental induction of enterocolitis in guinea pigs, while some compounds produced by B. pumilus were reportedly toxic to mice, eukaryotic cells and humans (20,21,24,32).…”

Bacillus species constitute a diverse group of bacteria widely distributed in soil and the aquatic environment. In this study, Bacillus strains isolated from the coastal environment of Cochin, India were identified by detailed conventional biochemical methods, fatty acid methyl ester (FAME) analysis and partial 16S rDNA sequencing. Analysis of the data revealed that Bacillus pumilus was the most predominant species in the region under study followed by B. cereus and B. sphaericus. The B. pumilus isolates were further characterized by arbitrarily primed PCR (AP-PCR), antibiotic sensitivity profiling and PCR screening for known toxin genes associated with Bacillus spp. All B. pumilus isolates were biochemically identical, exhibited high protease and lipase activity and uniformly sensitive to antibiotics tested in this study. One strain of B. pumilus harboured cereulide synthetase gene cesB of B. cereus which was indistinguishable from rest of the isolates biochemically and by AP-PCR. This study reports, for the first time, the presence of the emetic toxin gene cesB in B. pumilus.
