Occurrence and molecular characterization of Cryptosporidium spp. isolated from domestic animals in a rural area surrounding Atlantic dry forest fragments in Teodoro Sampaio municipality, State of São Paulo, Brazil

The aim of this study was to assess the occurrence of Cryptosporidium in domestic animals in rural properties surrounding rain forest fragments within the municipality of Teodoro Sampaio, southeastern Brazil. Conventional sucrose flotation method followed by molecular characterization of the parasites by sequencing PCR products amplified from SSU rRNA gene were used. Stool samples were collected from domestic animals raised as pets and livestock in all rural properties surrounding three forest fragments. Samples from cattle (197), equine (63), pigs (25), sheep (11), and dogs (28) were collected from 98 rural properties. The frequency of occurrence of Cryptosporidium within each animal species was 3.0% (6/197) among cattle and 10.7% (3/28) among dogs. Cryptosporidium was not detected in stool samples from equine, sheep, and pigs. All sequences obtained from the six samples of calves showed molecular identity with Cryptosporidium andersoni while all sequences from dog samples were similar to C. canis. The frequency of occurrence of Cryptosporidium in these domestic animal species was low. The absence of C. parvum in the present study suggests that the zoonotic cycle of cryptosporidiosis may not be relevant in the region studied. The presence of Cryptosporidium species seldom described in humans may be, otherwise, important for the wild fauna as these animals are a source of infection and dissemination of this protozoan to other animal species. The impact and magnitude of infection by C. andersoni in wild ruminants and C. canis in wild canids have to be assessed in future studies to better understand the actual importance of these species in this region.

Leishmaniose tegumentar americana: flebotomíneos de área de transmissão no município de Teodoro Sampaio, região sudoeste do Estado de São Paulo, Brasil

Realizaram-se coletas de flebotomíneos em zona de mata secundária no município de Teodoro Sampaio, Estado de São Paulo, no período de 12 meses a partir de maio de 1994. Foram selecionadas duas residências localizadas a 240 e 850m da mata com características de floresta tropical semi-decídua. Coletas noturnas com armadilhas Center of Disease Control foram realizadas quinzenalmente de crepúsculo a crepúsculo, no intradomicílio, margem e interior da mata e nos peridomicílios. Com armadilhas de Shannon, localizadas no peridomicílio, foram realizadas 24 coletas de 6 horas a partir do crepúsculo vespertino e 4 coletas trimestrais noturnas de crepúsculo a crepúsculo. Observou-se baixa densidade populacional desses insetos, com predomínio de Lutzomyia intermedia (93,5%). Foi capturado maior número de insetos nas armadilhas instaladas na margem da mata. No peridomicílio de ambas as casas, capturou-se número equivalente de exemplares, porém, na casa mais distante da mata, houve nítido predomínio de machos. No intradomicílio da casa mais próxima à mata, foi capturado maior número de exemplares com predomínio de fêmeas. Os picos de L. intermedia e L. whitmani ocorreram nas coletas do primeiro horário e caracterizaram-se por maior freqüência nos meses de maio, setembro e dezembro, quando se registraram variações de temperatura média de 21 a 25,7O C e de índice pluviométrico de 66,7 a 195,1mm.

Taeniosis-cysticercosis complex in individuals of a peasants' settlement (Teodoro Sampaio, Pontal of Paranapanema, SP, Brazil)

In order to evaluate the taeniosis-cysticercosis complex in a population of a peasants' settlement, located at Teodoro Sampaio, state of São Paulo, Brazil (longitude 52° 36'12 ", latitude 22° 17'12 ") a series of laboratory markers were determined. After signing an informed consent, participants answered a standardized questionnaire. To determine anti-Taenia solium cysticercus antibodies, the samples were tested by enzyme linked immunoabsorbent assay using 18-and 14-kDa antigen proteins from vesicular fluid of Taenia crassiceps (VF-Tcra). The reactive and inconclusive ELISA samples were tested by immunoblotting. Total IgE levels were determined by chemmiluminescence's assay and hemogram by flow cytometer flux counter. A total of 84 individuals, 5.9% presented anti-T. solium cysticercus antibodies in ELISA and 3.6% were strongly reactive in the 18/14 kDa immunoblotting confirmatory test. All of the individuals with positive antibodies showed elevated Total IgE levels. We conclude that the frequency of anti-T. solium cysticercus antibodies in this population is higher than other regions considered endemic in São Paulo. Thus, it is important to carry out surveys in Peasants' settlement areas with the objective of establishing public health measures for prevention and control of infectious diseases such as taeniosis-cysticercosis.

Efeitos do sexo, do vigor e do tamanho da planta hospedeira sobre a distribuição de insetos indutores de galhas em Baccharis pseudomyriocephala Teodoro (Asteraceae)

Several hypotheses have been proposed to explain the patterns of host plant utilization by herbivorous insects in natural communities. We tested four hypotheses aiming to understand the pattern of attack by gall-inducing insects on the dioecious shrub, Baccharis pseudomyriocephala (Asteraceae). The shrub occurs in the Parque Estadual do Itacolomi, Southeastern Brazil, and supports ten species of galling insects. The following hypotheses were tested: i) male plants are more attacked by galling insects than female plants; ii) larger plant modules are preferentially attacked by galling insects; iii) galling insects perform better on larger modules than on smaller modules; iv) galling insects increase in abundance with meristematic availability. To address these questions, 240 plants (120 of each sex) were sampled in both reproductive and vegetative periods. We recorded the growth rate (4 cm), inflorescence and fruit production, attack rates of the galling insects, and their survivorship and mortality per shoot (module). Modules were separated into size classes (cm) and analyzed by regressions and ANCOVAs. Module size and reproductive effort were positively correlated with host plant size. We did not observe any effect of host plant gender on either variables. In the same way, host plant sex did not show any influence on the abundance and richness of galling insects. Although the abundance of galling insects showed a positive correlation with shoot size, the trend disappeared when the analyses were performed taking into consideration the number of galls per unit of growth (number of galls/cm of shoot) or biomass (number of galls/dry weight). Larval survivorship was not influenced by shoot size. Also, we observed that the abundance of one species of hemipteran galling insect showed a positive relation with leaf biomass. Therefore, we conclude that gender and vigor of this plant species do not influence the community structure of its galling herbivores.

Erosividade da chuva: distribuição e correlação com a precipitação pluviométrica de Teodoro Sampaio (SP)

Foram separadas 812 chuvas individuais consideradas erosivas de uma série contínua de 19 anos de registros de dados pluviográficos. As chuvas selecionadas foram cotadas, digitalizadas e, posteriormente, analisadas pelo programa desenvolvido por Cataneo et al. (1982). O fator erosividade da chuva, expresso pelo parâmetro EI30 médio anual calculado, foi de 7.172 MJ mm ha-1 h-1 ano-1, fator esperado no local pelo menos uma vez a cada 2,33 anos, com uma probabilidade de ocorrência de 42,9 %. Os valores anuais de erosividade de Teodoro Sampaio, esperados nos períodos de retorno de 2, 5, 10, 20, 50 e 100 anos, foram, respectivamente, de 6.831, 8.666, 9.877, 11.046, 12.546 e 13.675 MJ mm ha-1 h-1 ano-1. No semestre de outubro a março, ocorreu 74,0 % da erosividade anual, sendo 45,7 % de dezembro a fevereiro. Observou-se elevada correlação entre o parâmetro EI30 médio mensal e o coeficiente de chuva (P²/P). Portanto, a equação de regressão determinada permite que seja estimado, com boa margem de segurança, o fator R para outros locais que não disponham de dados pluviográficos, mas que, entretanto, tenham dados pluviométricos e condições climáticas semelhantes às de Teodoro Sampaio (SP).

Teodoro Falcón Márquez: El Palacio de las Dueñas y las casas-palacio sevillanas delsiglo XVI.Fundación Aparejadores, Sevilla 2003.

Tal com apunta l'autor en un dels primers apartats del llibre, el lloc preeminent que ocupa el palau de las Dueñas dins el conjunt de les construccions senyorials sevillanes renaixentistes queda evidenciat en el fet que és l'únic d'aquests edificis que és denominat amb el rang de palau; la resta reben la qualificació de cases, indicativa no tant de la menor entitat artística d'aquestes altres mansions, sinó de la importància representativa que adquirí la construcció que ens ocupa, magnificada especialment pel fet que acabà sent propietat de la més distingida de les famílies anomenades «Grandes de España», la casa d'Alba.
