Why Use the Mini-FLOTAC to Detect Metastrongyloid Larvae in Dogs and Cats?

Abstract

Purpose

Canine and feline cardiopulmonary disease is an emergent condition in several European countries, particularly in non-endemic regions, although it is often underestimated because of the limitations of the common diagnostic techniques. The aim of this study was to evaluate the performance of Mini-FLOTAC to detect cardiopulmonary larvae from dogs and cats compared to reference techniques such as Baermann and FLOTAC.

Methods

A total of 20 fresh faecal samples were collected from ten dogs and ten cats naturally infected with Angiostrongylus vasorum, and Aelurostrongylus abstrusus and Troglostrongylus spp., respectively. Three replicates were performed for each technique. FS3 (zinc sulfate, specific gravity = 1.200) was used as flotation solution for Mini-FLOTAC and FLOTAC. The results were expressed as the arithmetic mean of LPG (larvae per gram of faeces).

Results

The mean LPG calculated by means of Mini-FLOTAC was significantly higher (P < 0.05) than that obtained through the Baermann technique for A. vasorum, A. abstrusus and Troglostrongylus spp., whereas it was significantly higher (P < 0.05) than that obtained through the FLOTAC technique only for A. vasorum and A. abstrusus.

Conclusions

Mini-FLOTAC can be considered a valid alternative for the detection of metastrongyloid larvae of dogs and cats, overcoming the limitation of time required by the Baermann test.
