Contamination by Toxocara spp. and Ancylostoma spp. in areas of leisure from Canoinhas County, Santa Catarina state

Visceral and cutaneous larva migrans are zoonoses caused by the Toxocara spp. and Ancylostoma spp. respectively. The objective of this research was to evaluate the contamination for these agents in areas of leisure from the city of Canoinhas, Santa Catarina, by means of the techniques of spontaneous sedimentation, centrifugal sedimentation and centrifugal fluctuation. From the examined areas of leisure, 100% had disclosed the contaminated sand and 80% excrements contaminated by Ancylostoma spp and/or Toxocara spp.. Of these, 100% had presented contamination for the Ancylostoma spp and only one presented contamination with eggs of Toxocara spp..The presence of Ancylostoma spp. and Toxocara spp. in the analyzed sand samples was of 39%. In the excrement examinations collected in the leisure areas 17% of positive samples had been detected, being detected only eggs of Ancylostoma spp. The study it demonstrated that the contamination of the areas of leisure of the Canoinhas city, is preoccupying, strengthening the necessity to implement measured effective for control of zoonoses in leisure areas.Larva migrans visceral e cutânea são zoonoses causadas por Toxocara spp. e Ancylostoma spp., respectivamente. O objetivo desta pesquisa foi avaliar a contaminação por estes agentes em áreas de lazer do município de Canoinhas, Santa Catarina, por meio das técnicas de sedimentação espontânea, centrífugo sedimentação e centrífugo flutuação. Das áreas de lazer examinadas (n=5), 100% apresentaram a areia contaminada e 80% apresentaram fezes contaminadas por Ancylostoma spp e/ou Toxocara spp. Destas, 100% apresentaram contaminação pelo Ancylostoma spp e apenas uma apresentou contaminação com ovos de Toxocara spp.. A presença de Ancylostoma spp. e de Toxocara spp. nas amostras de areia analisadas foi de 39%. Nos exames de fezes coletadas nas áreas de lazer foram detectadas 17% de amostras positivas, sendo detectado apenas ovos de Ancylostoma spp. O estudo revelou que a contaminação das áreas de lazer do município de Canoinhas é preocupante, reforçando a necessidade de implementar medidas efetivas para controle de zoonoses em áreas de lazer

First isolation of Dioctophyme renale eggs from an urban environment and identification of those from animal urine

Abstract Dioctophyme renale is a zoonotic parasite with worldwide distribution, although its occurrence is little known. The objective here was to evaluate the presence of parasite eggs in the environment and in the urine of dogs and cats in an urban area. Soil samples and urine were evaluated respectively by means of the Caldwell-Caldwell technique and urinalysis. Out of the 100 soil samples, 3% presented D. renale eggs, and out of the 43 urine samples, 18.6% were positive, including the feline samples. Thus, D. renale eggs are present in the urban environment, and dogs and cats are parasitized by this nematode, which therefore represents a risk to public health
