Fig. 2From: Angiostrongylus vasorum and Aelurostrongylus abstrusus: Neglected and underestimated parasites in South AmericaIllustration of modified Baermann funnel techniques. This technique is considered as the gold standard for the diagnosis of lungworm infections in cat and dog faeces. a A household funnel is combined with a plastic tube of 10 cm length and closed by a metal tubing clamp. The funnel is filled with handwarm tap-water. Then a wire mesh screen (9 cm diameter, 0.20–0.25 mm aperture) has to be set in the top of the funnel. b Modification by Conboy et al. [104]: instead of a funnel, 50 ml screw-top centrifuge tubes containing warm tap water are used. The faeces need to be placed in a double layer of cheesecloth, placed in the tube and the cap is screwed onto the tube catching a small part of the cheesecloth to keep it in place at the top at the tube.
