“…Concerning the Brazilian cities, our results with hookworms in Guarulhos were similar to the recorded in Araçatuba (São Paulo State) by NUNES et al (2000) 28 , who found 46% of the sand samples contaminated with Ancylostoma spp. larvae.…”

“…In this study, soil samples were analyzed using the flotation technique according to DADA (1979) 9 with sodium dichromate (d = 1.35) and zinc sulphate (d = 1.20) for helminth eggs and the modified Baermann method for larvae recovered according to RUGAI et al (1954) 38 . Although the methods used to recover zoonotic parasites in soil are not standardized and are not always comparable 23,26 , the techniques used in our study are in agreement with others studies and they are considered effective 16,21,23,28 . Another important aspect in parasite detection is the type of soil 21,22,23,26,41 .…”

“…larvae. On the other hand, the degree of contamination by hookworm was higher than recovered in some cities, such as Fernandópolis, São Paulo (1.8%) 5 , Santos, São Paulo (15%) 35 , Duque de Caxias, Rio de Janeiro (33.5%) 42 and Araçatuba, São Paulo (37.5%) 28 . In contrast, contamination rates higher than our results were noted in Santa Maria (Rio Grande do Sul State) by CORRÊA & MOREIRA (1996) 8 , who found 93.3% of the public squares' land contaminated with eggs of Ancylostoma spp.…”

SUMMARYThe contaminated soil with mammal feces is an important factor of risk to infection with zoonotic diseases. Amongst these zoonoses are visceral larva migrans and cutaneous larva migrans caused by Toxocara spp. and Ancylostoma spp., respectively. The aim of this study was to assess the environmental contamination by Toxocara spp. eggs and hookworms (Ancylostoma spp.) in public parks and squares in the city of Guarulhos, a metropolitan area of São Paulo, São Paulo State, Brazil. Soil samples were collected, between September and December 2010, and examined using the centrifugal flotation technique with sodium dichromate and zinc sulphate as well as the modified Baermann method. Notably, 35 (74.5%) of the 47 districts surveyed in Guarulhos possessed samples contaminated with Toxocara spp. and/or eggs or larvae of Ancylostoma spp. The frequency of Toxocara spp. and Ancylostoma spp. in the samples from public areas was 68.1% and 46.8%, respectively. Overall, the eastern side of Guarulhos is the region with the highest occurrence of causative agents of larva migrans. In all collection sites, the presence of feces from dogs and cats accompanied by their owners and stray animals were observed. Notably, it is important to adopt measures to control dog and cat breeding, to treat infected animals, and provide health education to the population.

“…No Brasil, o A. braziliense e o A. caninum são os principais agentes etiológicos desta afecção (Nunes et al, 2000). Esta zoonose pode ocorrer nos locais que possuem cães e/ou gatos infectados por ancilostomídeos (Nunes et al, 2000). Porém, esta zoonose se torna mais grave e é mais freqüente em praias e em terrenos arenosos (caixas de areia, campos de futebol, quadras de vôlei), onde as condições ambientais favorecem a evolução destes nematódeos até a sua forma infectante.…”

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.

Toxocarosis is one of the most prevalent human helminthosis caused by larvae of Toxocara canis and Toxocara cati, the most widely distributed nematode parasites of dogs and cats respectively. Soil is considered as the principal source of transmission of Toxocara infection to human beings. With increasing population of dogs and cats, soil contamination with ova or eggs of Toxocara can be detected in public and private locations of city backyards, playgrounds, streets, sand pits and so on, regardless of the season of the year. In this context the present study was carried out to estimate the extent of soil contamination with Toxocara eggs in public parks, playgrounds and few kennels situated in different parts of Chennai city. A total of 105 soil samples from 40 public places and 5 kennels were screened for the presence of parasitic eggs. Toxocara eggs were recovered from 5 soil samples indicating an overall prevalence rate of 4.75 %. Out of 80 samples collected from public places, three samples, one each from Mogappair, My lady park (Periamet) and Madras Veterinary College showed the presence of Toxocara spp. eggs indicating an overall prevalence of 3.75 per cent. Out of the 25 samples from 5 kennels, two samples one each from Tambaram and Thorappakkam kennels were positive for Toxocara eggs with prevalence of 8 per cent. Low prevalence of Toxocara eggs in soil samples of these areas can be attributed to the less population of pups, the carriers of adult worms and the active source of soil contamination. The progress made in ABC (animal birth control) programme carried out by both governmental and nongovernmental organizations has contributed to reduction of birth rate in dogs and thereby reduced the chances of soil contamination with Toxocara eggs to a certain extent in Chennai city.
