BOHRF Original Authors' Main Conclusions
The original authors' main conclusions are taken from Abstract, Results and
Discussion. They are decided upon by the authors of the BOHRF occupational
asthma guidelines and form part of the guidelines.
In a survey of 121 workers exposed to dusts containing derivatives of bacillus subtilis, mainly proteolytic enzymes, skin tests showed evidence of sensitisation was higher among atopic subjects - 16/25 (61%) than among non-atopic subjects - 32/96 (33%). Reduced ventilatory capacity was found in 44% of sensitised workers compared with 14% of those not sensitised.
The following comments are from the editors of the BOHRF occupational asthma guidelines
and form part of the guidelines.
A selection of common allergens was tested and the reactions to these extracts were used as the criteria for classifying subjects as atopic and non-atopic
