“…Apart from Penicillium glabrum, a fungus implicated in the early descriptions of suberosis, recently, Chrysonilia sitophila has been also identified throughout the manufacturing process of cork (Danesh et al 1997) and, as in the logging industry, may play a role in cork workers' occupational asthma (Tarlo et al 1996). In our study, using skin testing and immunoblotting for the detection of specific IgE antibodies to Penicillium glabrum, Chrysonilia sitophila and Trichoderma longibrachiatum, the most prevalent moulds in the manufacturing process of stoppers (Danesh et al 1997), we did not find evidence of allergic sensitisation in patients with asthma in the cork industry, although an antibody response (IgG4) was evident in some cases (Fig.…”
