Abstract

Abstract Toxocara spp. are zoonotic helminths of domestic and wild mammals and have been implicated in serious human disease. The present study was undertaken to differentiate among various adult Toxocara spp. infecting some wild and stray mammals and to evaluate the frequency of infection by Toxocara in wild mammals that may serve as a potential source of Toxocara infection in humans. Infection by adult Toxocara canis (Warner, 1782) was found in 31 of 58 (53.4%) domestic dogs (Canis lupus familiaris), 20 of 41 (48.8%) red foxes (Vulpes vulpes), 27 of 43 (62.8%) grey wolves (Canis lupus); and 25 of 42 (59.5%) Egyptian mongooses (Herpestes ichneumon); the grey wolf and the Egyptian mongoose are new host records for Egypt. Toxocara cati (Schrank, 1788) Brumpt, 1927, was found in 27 of 46 (58.7%) wild cats (Felis sylvestris). The mean intensity and abundance of T. canis was highest in grey wolves and lowest in red foxes. The prevalence, intensity, and abundance varied with host species, sex, and season. Prev...
