Use of the FLOTAC technique for the diagnosis of Aelurostrongylus abstrusus in the cat

Aelurostrongylus abstrusus is a lungworm of the domestic cats distributed worldwide. Its presence, however, is often underestimated due to limitation of common coprological diagnostic techniques. The present study reports, for the first time, the use of the FLOTAC technique for A. abstrusus diagnosis in feline faecal samples with results compared to the following three standard copromicroscopic techniques: the Baermann technique, the McMaster technique and the Wisconsin technique. The comparison study showed that the FLOTAC technique produced mean larvae per gram of faeces significantly (P<0.05) greater than that produced by the other more widely used diagnostic tools. Thus, the FLOTAC technique can be utilised for quantifying lungworm larva burdens in feline faecal samples because of its high sensitivity, as already shown for various parasites of veterinary and human importance.
