title: [Exposure to organic dust and microorganisms as a factor affecting respiratory function of workers of purebred horse farms].
abstract: In two farms of purebred horses, microbiological studies of the air and medical examination of the workers were performed. The concentration of microorganisms in the air were within the range 29.2-336.0 cfu x 10(3)/m3. The respirable fraction in most cases was between 30-60% of the total count. The levels of dust and endotoxin were low except for one sampling point where the concentration of endotoxin was as high as 3.44 g/m3. As many as 16 workers out of the total of 31 examined reported occurrence of work-related symptoms. However, the results of physical examination and of lung function tests were within normal range. A high proportion of workers showed a positive skin response to Saccharopolyspora rectivirgula (51.6%) and the presence of precipitins to Acinetobacter calcoaceticus (32.3%). No significant relationship could be found between the presence of symptoms and positive allergological reactions. Total medical results indicate the probability of the occurrence of Organic Dust Toxic Syndrome in high proportion of the workers.
