SUMMARYThe objective of this study was to describe the occurrence of intestinal parasites inside public restrooms and buses from a Brazilian city. Sample material was obtained using a transparent adhesive tape. Thirty two public restrooms were investigated and two (6.25%) were contaminated with helminth eggs (Ascaris lumbricoides and Enterobius vermicularis). Of the sixteen different bus lines, three (18.7%) were found to harbor eggs of E. vermicularis. Public restrooms and buses can be an important source of parasite transmission and sanitary education could be improved by using these points. KEYWORDS:Public restroom contamination; Bus contamination; Intestinal parasites; Brazil.Enteroparasites are a serious public health problem in developing countries and they are directly related to precarious sanitation 14 . The transmissible stages (eggs, larvae, cysts and oocysts) can be found in the environment, either in soil, water or food, as a consequence of direct or indirect contamination with human or animal feces 2 . The prevalence of soil-transmitted helminthes (A. lumbricoides, the hookworms Ancylostoma duodenale and Necator americanus, Trichuris trichiura and Strongyloides stercoralis), provides useful information about the extent of the public health problem, and are being used to guide the growing efforts to control disease. To reduce the prevalence of these parasites, it is necessary to improve social economic conditions and provide better basic sanitation. Sanitary education along with changes in cultural habits is also a relevant factor 12 . The contamination of bathroom installations can promote the dissemination of enteroparasites 1,5,9 . In this sense, public transport vehicles are also an important source of infection 7,10,11 .The objective of this study was to determine the occurrence of intestinal parasites in public restrooms and buses in the city of Uberlândia, Minas Gerais, during the period from August to November, 2007.The research was conducted in the urban area of Uberlândia (18° 91' 86" S and 48° 27' 72" W), Minas Gerais, in the southeast region of Brazil. Uberlândia has a population of 608,369 4 , with 97.6% living in the urban area. The city offers 100% treated water and more than 90% sewage treatment.Thirty-two public restrooms were examined in thirteen locations: one bus station, five urban bus terminals, six public squares, and one public park. In each place, one female restroom and one male restroom were investigated, except for the public park, where four female restrooms and four male restrooms were evaluated. Inside the restrooms, a total of 192 samples were collected from door latches, toilet seats, which were divided into four quadrants (front, rear, right and left rim) and flush cords 1 .In Uberlândia, the public transport system is composed of 16 different bus lines that start from downtown and reach different regions of the city. One bus from each line was analyzed and the samples were collected from the turnstile, support bars (front and rear), seats (front and rear), and stop...

“…es un parásito intestinal que se ha relacionado con síntomas como náuseas, vómito, flatulencia, prurito anal, disminución de peso, malestar general, anorexia, fiebre y pérdida de sangre en las deposiciones. También se ha asociado con otros trastornos tales como urticaria, eosinofilia y síndrome de colon irritable (5)(6)(7)(8). En los niños es más frecuente asociarlo con diarrea aguda y crónica, dolor y distensión abdominal (1,9).…”

“…Since the number of dogs bred in rural areas and in cities has recently been increasing worldwide, the human risk of parasitic infections has been expected to increase as well (DUBNÁ et al, 2007). Different cases of human infections caused by Trichuris spp., Hymenolepis nana, E. granulosus, Giardia lamblia and Toxocara canis, were reported in the provinces of Buenos Aires, Neuquén, and Salta, in Argentina (TARANTO et al, 2000;BASUALDO et al, 2007;CESANI et al, 2007;PIERANGELI et al, 2007;DOPCHIZ et al, 2011;GAMBOA et al, 2011). One important parasitic disease is the cystic echinococcosis (CE), an infection of humans and herbivorous animals, caused by the larval stage of the parasite E. granulosus.…”

Dogs are definite hosts for several zoonotic helminthes and protozoan. Rural areas from the Lobos District in the northeast of Buenos Aires province, Argentina, are mainly used for livestock activity, increasing in this way the number of dogs on farms as well as the human risk of parasitic infections. The aims of this research were to evaluate the endoparasitic infections in dogs from farms in the Lobos District and analyze their zoonotic importance as well as several risk practices and habits of the rural population. Forty-two dog fecal samples obtained in 21 farms were analyzed through coproparasitological methods and coproantigen tests, which resulted in an overall parasite prevalence of 69.05% and 80.95% of the parasitized farms. The most frequent parasites were Trichuris vulpis and Eucoleus aerophila (26.19%), Echinococcus granulosus (19.05%), Uncinaria stenocephala and coccids (14.29%). The analysis of epidemiological files showed several habits of the rural population considered as risk factors associated with the presence of fecal samples parasitized and the presence of E. granulosus on the farms. It is clear that people involved with the farms studied were exposed to several helminthes that could cause serious diseases like cystic echinococcosis, which can become an important public health issue and affect the economy worldwide.Keywords: Parasites, zoonoses, rural areas, dogs. ResumoOs cães são hospedeiros definitivos de vários helmintos e protozoários zoonóticos. As áreas rurais do distrito de Lobos, no nordeste da província de Buenos Aires, Argentina, destinam-se principalmente à atividade pecuária aumentando desta forma o número de cães em fazendas, bem como o risco humano de infecções parasitárias. Os objetivos desta pesquisa foram avaliar as infecções endoparasitas em cães de fazendas do distrito de Lobos e analisar a sua importância zoonótica, bem como as práticas de risco e hábitos da população rural. Quarenta e duas amostras de fezes de cães obtidos em 21 fazendas foram analisadas pelos métodos coproparasitológicos e testes de coproantígenos, resultando numa prevalência de parasitas de 69,05% e 80,95% das propriedades parasitados. Os parasitas mais frequentes foram Trichuris vulpis e Eucoleus aerophila (26,19%), Echinococcus granulosus (19,05%), Uncinaria stenocephala e coccídeos (14,29%). A análise dos arquivos epidemiológicos mostraram vários hábitos da população rural como fatores de risco associados com a presença de amostras fecais parasitadas e a presença de E. granulosus em propriedades rurais. É evidente que as pessoas das fazendas estudadas foram expostas a vários helmintos que podem causar doenças graves como equinococose cística, que constitui importante problema de saúde pública e econômico a nível mundial.
