[Comparison of 4 technics for collecting bacteria on cement, asbestos-cement and steel in hen-breeding buildings].
A comparative study between 4 sampling techniques (swabbing, pistol-washing, printing on agar medium either with or without neutralizer) was performed on three materials (concrete, asbestos-concrete, steel) following numeration of three bacterial flora (the total aerobic flora, faecal streptococci, pseudomonas). The highest levels of contamination were detected with pistol-washing irrespective of the substrate and flora recovered. A correlative study carried out from the contamination levels reveals that a significant correlation exists in all cases, with a low probability of error.
