Enteroparasites prevalence among daycare and elementary school children of municipal schools, Rolândia, PR, Brazil Prevalência de enteroparasitoses em crianças de creches e alunos da rede municipal de ensino de Rolândia, Paraná

Coproparasitological analyses were performed on 191 daycare children and 434 elementary school children from urban and rural areas in Rolândia, Parana State, Brazil. The overall prevalence of enteroparasites was 15.2 % for daycare children and 52.5% for elementary school children. Risk factors are discussed.<br>Exames coproparasitológicos realizados em 191 crianças de creches e em 434 alunos da primeira à quarta série das áreas urbana e rural da rede municipal de Rolândia, PR, evidenciaram enteroparasitas em prevalência de 15,2% nas creches e de 52,5% entre os escolares.

Correlação entre condições de saneamento básico e parasitoses intestinais na população de Assis, Estado de São Paulo Correlation between sanitation conditions and enteroparasitoses in the population of Assis, São Paulo State, Brazil

Foi estudada a distribuição dos enteroparasitos mais freqüentes na população de Assis, São Paulo, de 1990 a 1992. Foram analisados 18.366 exames oriundos de seis postos de atendimento sanitário (PAS): Vila Marialves, Vila Progresso, Centro, Vila Xavier, Vila Fiúza e Vila Bonfim. A prevalência de enteroparasitoses geral foi 23,3%. Os enteroparasitos mais encontrados foram: Giardia intestinalis (8,7%), Ascaris lumbricoides (5,5%), Trichuris trichiura (2,4%) e Hymenolepis nana (1,9%). Na Vila Marialves, região de baixo nível sócio-econômico essas freqüências foram, respectivamente: 17%; 13,1%; 5,9% e 4,2%. A faixa etária 3 a 12 anos apresentou maior número de indivíduos parasitados. Estabeleceu-se uma correlação entre as condições de saneamento básico, expressos pelo número de ligações de água e esgoto, e a freqüência de parasitoses. Houve queda na freqüência de parasitoses nos PAS entre 1990 e 1992, coincidindo com o aumento do número de ligações de água e esgoto nestas regiões.<br>The distribution of the most frequent enteroparasites in the population of Assis, State of São Paulo, was studied from 1990 to 1992. A total of 18,366 medical examinations from six sanitary care centers in the neighbourhoods of Marialves, Progresso, city center, Xavier, Fiúza and Bonfim were analized. The general prevalence of enteroparasites was 23.3%. The most frequently found enteroparasites were: Giardia intestinalis (8.7%), Ascaris lumbricoides (5.5%), Trichuris trichiura (2.4%) and Hymenolepis nana (1.9%). In Marialves, a low income neighborhood, the prevalences were: 17%; 13.1%; 5.9% and 4.2%, rspectively. The age group from 3 to 12 years showed the largest number of infected individuals. There was a correlation between basic sanitation conditions, expressed as the number of places connected to the city water and sewage systems, and the prevalence of parasites. There was also a decrease of parasite prevalence in all sanitary care centers from 1990 to 1992, which coincided with the increase in the number of new water and sewage systems in these neighborhoods

Estudo morfométrico do gênero Panstrongylus Berg, 1879 (Hemiptera, Reduviidae, Triatominae) Morphometric study of the genus Panstrongylus Berg, 1879 (Hemiptera, Reduviidae, Triatominae)

<abstract language="eng">The subfamily Triatominae is actually represented by 137 species distributed among 6 tribes and 19 genera. Within this subfamily, the genus Panstrongylus, Berg 1879, is composed by 13 species widespread in sylvatic, peridomestic, and domestic habitats of Neotropical regions. These species are vectors of Chagas disease and consequently are found associated with its main hosts, such as birds and mammals. Interest in species of this genus has been increasing in the last few years. Reports of several authors indicate these Triatominae to invade and colonize houses, increasing their epidemiological significance. Morphometry was used in this study to investigate correlations among possible closely related species. We measured 224 specimens among 13 species through a set of metric variables of the head. The results indicated that the genus Panstrongylus seems to be homogeneous since 10 of the 14 species were shown to be closely related
