ABSTRACT

Toxocara canis is one of the most common parasitic helminth worms of dogs that causes zoonotic disease in humans. The study was conducted to determine the effectiveness of flotation technique with commonly used flotation fluids in recovering Toxocara canis ova from soil samples collected from different public places viz. public parks, playgrounds, sidewalks/ road side and garden soil. The study revealed that sodium nitrate flotation fluid gave best results in recovering T. canis ova from the soil samples, both positivity as well as in intensity, as compared to sodium chloride and zinc sulphate flotation fluids. Public parks were found to be most contaminated with T. canis ova, followed by sidewalks/road sides, play grounds and garden soil. All the ova recovered from the environment were viable and potentially infective.

Key words: Efficacy, flotation techniques, recovery, soil, Toxocara canis ova
