“…Canine feces are frequent in public places and playgrounds in other countries, as reported by other authors around the world 1,5,15,22,24,33 . Although limited studies about soil contamination with Toxocara eggs in Peru have revealed a frequency ranging from 30% to 80% 19 . It is possible that the infection occurring in this population might have also happened by an accidental ingestion of infective Toxocara eggs from the soil of those public places.…”

“…In Peru, a few reports have informed of frequencies from 7.8% to 44.92% in rural populations from different places [7][8][9]19,30,31 . However, seroepidemiological studies about human toxocariasis in Peruvian Amazonian populations have not been reported.…”
SUMMARYThe aim of this study was to determine the seroprevalence of the infection by Toxocara in the general population of the Amazonian city of Yurimaguas, Peru. From March to August 2008, a total of 300 subjects were sampled and tested by means of a Toxocara ELISA-IgG test. A clinical and epidemiological questionnaire was used to assess the symptomatology and risk factors associated with human toxocariasis. The overall rate of seropositivity was 35.66%, with a significant high proportion in children (p < 0.001). The clinical evaluation revealed that 95.33% of the seropositive group had some type of symptomatology: headache (66.36%), respiratory compromise (63.55%), abdominal pain (54.21%), cutaneous signs (40.19%) and ocular manifestations (36.45%), and almost all of them were statistically significant (p < 0.001). Furthermore, 56.07% of the seropositive subjects presented at least one intestinal pathogen parasite with predominance of helminthes, but without significant association (p = 0.334). The analysis of risk factors showed only that the use of public places and geophagia exhibited a significant association with the seropositivity (p < 0.001). Clinical, serological and epidemiological findings associated to infection with Toxocara were observed in the present study and future studies should be done to assess this serious health problem.

“…Eggs of ascarids, and particularly of Toxocara, are highly resistant to environmental conditions, remaining viable and infective for long periods 63 reported the retention of infectivity of at least 11 months for Toxocara canis eggs maintained at 28 o C in a 2% formalin solution. In addition, CHUNG et al 30 observed a greater survival rate when the eggs were maintained at 4 o C. However, certain environmental factors can influence the evolution of Toxocara eggs in the soil 48,54 .…”

SUMMARYIn the present paper the main aspects of the natural history of human infection by Toxocara larvae that occasionally result in the occurrence of visceral and/or ocular larva migrans syndrome were reviewed. The contribution by Brazilian researchers was emphasized, especially the staff of the Tropical Medicine Institute of São Paulo (IMT).
