Soroprevalência de Toxoplasma gondii em rebanhos caprinos no Estado de São Paulo

Four hundred forty-two serum samples were collected from dairy goats in seven regions of São Paulo State. These were tested for Toxoplasma gondii antibodies using the indirect immunofluorescent antibody test. Sixty-four (14,5%) serologically positive animals were found from all these goat farms studied.

Efeito da salinidade e do esgoto orgânico sobre a comunidade zooplanctônica, com ênfase nos copépodes, do estuário do rio Itanhaém, Estado de São Paulo

The objective of this work is to analyze the effects of salinity and wastewater on the zooplankton community of the Itanhaém river estuary, São Paulo state. Samples of zooplankton as well as physical and chemical variables of water were collected in four sites, located between the coastal line and the superior part of the estuary, including a secondary channel where wastewater is thrown without previous treatment. The samples were collected in low and high tide in winter and summer. Results showed that the estuary presents a temporal and spatial variation of physical and chemical characteristics, especially salinity, in function of the tide and seasonal variation of rain. The high values of salinity occurred in winter and high tide. Zooplankton community was adapted to the dynamic of salinity, and marine and estuarine species occurred in the low part of the estuary in winter. Although the Itanhaém river estuary has the same temporal and spatial dynamic of other estuaries, the values of salinity are low when compared with others located in the southern coast of São Paulo. Consequently, mainly oligohaline and fresh water species constitute the zooplankton community. These characteristics are due to the great drainage area of the Itanhaém river basin. The waste water modified physical and chemical characteristics of water that now presents higher concentrations of nutrients, higher values of suspended matter and lower concentrations of oxygen. It was observed a positive relation between the density of nauplii of copepods and organic pollution in this estuary.

Habitat, distribuição e aspectos adaptativos de peixes da microbacia do ribeirão Grande, Estado de São Paulo, Brasil

The ichthyofauna of ribeirão Grande microbasin that runs through one of the few remaining fragments of Atlantic Forest (in Mantiqueira mountain range, Valley of Paraíba) was studied. Fish samples were obtained with an electric fishing powered by a maximum capacity generator of 155 V and 60-Hz alterning current, gill-nets and traps. In three collecting days, during July/2001, October/2001, January/2002 and April/2002, 2865 fishes were sampled. These fishes belonged to 12 families, 23 genera and 37 species. The species were more abundant between the piedmont and the plain of the Valley of Paraíba. The Characidium, Trichomycterus genera and the Imparfinis minutus species presented only one ovary or testis and no swim bladder. The ecological significance of morphological features in stream mountain fishes was used to predict the niche adaptation for those conditions, towards K-strategy.

Espécies do gênero Eimeria Schneider, 1875 (Apicomplexa: Eimeriidae) em caprinos leitros mantidos em sistema intensivo na região de São Jose do Rio Preto, estado de São Paulo, Brasil.

Were examined 58 dairy goats, 41 kids and 17 adults, Saanen and Alpine breeds, males and females, in intensive system, in the São José do Rio Preto region, São Paulo state, for detection and identification of Eimeria spp. oocysts. The 58 feces samples analyzed by the Centrifugal-flotation technique, were positive for, at least, one Eimeria species. The Eimeria species found in this research were: E. ninakohlyakimovae (77,6%), E. jolchijevi (72,4%), E. alijevi (63,8%), E. christenseni (63,8%), E. arloingi (62,1%), E. caprovina (56,9%), E. hirci (50,0%) and E. caprina (48,3%). It follows that the high rate of the positive animals and the high frequency of the Eimeria species among the animals demonstrated that the disease is common in dairy goats, kids and adults, in intensive system.

As rochas intrusivas da Formação Serra Geral na Porção leste da Bacia do Paraná no Estado de São Paulo: Aspectos petrográficos e geoquímicos - Resultados preliminares

The purpose of this paper is to present preliminary aspects of the petrography and chemistry of intrusive rocks (sills and dykes) from the eastern portion of the Parana Basin in the State of Säo Paulo. Data from 80 samples of the region show a subaphyric and subophitic nature and have plagioclase (25-50%), augite (3-39%), pigeonite (0-10%) and magnetite (4-20%) as an essential minerals. Apatite and quartz are present as accessory minerals. The geochemical data of intrusive rocks show a basic to intermediate composition (48% < SiO 2 < 56%) and a high Ti nature (TiO 2 > 2%). Based on the minor and trace composition of the intrusive rocks, two different magma types were recognized, named Paranapanema and Pitanga. The spatial distribution of these magma types is not alleatory in the studied region. The intrusive rocks of Pitanga magma type are displayed in the Campinas-Paulinia region, while the Paranapanema magma type cover a large region above that one, between Rio Claro and Cajuru. Furthermore, the chemical composition of the lava flows of the Serra Geral Formation, sampled in this work, reveals a magma of Urubici type. So, the intrusive rocks of the eastern portion of the of State Säo Paulo are not the extension of the lava flows, or they aren't a portions which don't reach the surface.

Propriedades físicas e infiltração de água de um Latossolo Vermelho Amarelo (Oxisol) do noroeste do estado de São Paulo, Brasil, sob três condições de uso e manejo

This study presents the results obtained in a field experiment carried out at Glicério, Northwest of São Paulo state, Brazil, whose objective was to analyze changes of selected soil physical properties and water infiltration rates on a Yellow-Red Latosol, under three different management conditions. The experimental design was arranged as completely randomized split-block with twelve treatments, which corresponded to four depths (0-0.05 m; 0.05-0.10 m; 0.10-0.20 m and 0.20-0.40 m) and three conditions of soil use and management with four replications. The soil surface conditions were: conventional tillage (one disking with moulboard plus two levelling passes with harrow), nine months before starting filed experiences; recent conventional tillage (also one disking with moulboard plus two levelling passes with harrow) and native forest. The conventional tillage areas were cropped for about fifteen years with annual cultures. The considered soil general physical properties were: macroporosity, microporosity, total porosity, bulk density, soil moisture and penetration resistance and, in addition; soil water infiltration rates were also recorded. According to our results, differences on general soil physical properties and infiltration rates appeared when both tilled sub-treatments and native forest were compared. Both, plots recently prepared by conventional tillage and those prepared by tillage but left nine months in rest, presented a statistically significant decrease of constant (final) water infiltration rates of 92.72% and 91.91% when compared with native forest plots.

Fitoterapia no sistema de saúde pública (SUS) no Estado de São Paulo, Brasil

Phytotherapy is a form of familiar treatment throughout the world and recommended by the World Health Organisation to be used in all regions, especially in the poorer countries, to improve the state of health of their people. The aim of this study was to describe the use of herbal medicine as an alternative therapy in the public health system in Sao Paulo State. The fieldwork consisted in obtaining information, from all the Regional Health Authorities in the State, about which municipal health areas use this therapy and sending them a questionnaire requesting details about the application of phitotherapy: when the therapy had been adopted, which plants were used, whether the programme had been discontinued or not and if so, for what reason. The cities that use the phytotherapy are: Campinas; Canas; Guaratingueta; Herculandia; Piquete; Pindamonhangaba; Roseira e Sao Jose do Barreiro, Ribeirao Preto, Sao Lourenço da Serra, Cruzeiro e Dobrada. And the three plant more used are: Guaco (Mikania glomerate); Calendula (Calendula officinalis) e Babosa (Aloe vera) The lack of support has led some Authorities to discontinue their active in 08 programmes. Nevertheless, it is concluded that the efficacy and low cost of herbal treatments has engendered a growing interest among health professionals in placing proposals for implanting this therapy in 13 cities in the Municipal Health. Thus, there should be growing practical support for the establishment of such programmes in the future.

Relação peso-comprimento e fator de condição de Brycon opalinus (Pisces, Characiformes) no Parque Estadual da Serra do Mar-Núcleo Santa Virgínia, Mata Atlântica, Estado de São Paulo, Brasil

In this study, the length-weight relationship and the condition factor of Brycon opalinus were analyzed in three rivers within the Santa Virgínia Unit, at Serra do Mar State Park, in São Paulo State. The different conditions in these three environments were evidenced, such as the seasonality, reproductive period, and the differences between females and males according to the parameters which evidenced the best physiological condition of the fish. In this species, the condition factor varied along the seasons at all three collection sites. The length of the first gonadal maturation and the reproductive period were long, with the highest intensity in the spring and summer.

Concentração de flúor nas águas de abastecimento público de municípios da região noroeste do estado de São Paulo, Brasil

It may be difficult for small and medium cities to obtain information about the fluoride content of public water, because of the lack of equipments and technicians. This study aimed to analyze the fluoride levels of the water supplied by the public treatment stations of 40 cities situated in the northwest region of São Paulo State, during a period of 6 months, to verify if fluoridation occurs in a continuous manner and if the fluoride levels are within the recommended. Maps of the water distribution system were obtained from the water treatment companies and utilized to randomize the addresses of the collection sites, so that they included all regions with treated water sources. One water sample by month was collected and analyzed in duplicate using an ion-specific-electrode. Samples with 0.6 to 0.8 mgF/L were considered acceptable. In the 38 cities that regularly provided the samples in the 6 months of the study, water from 144 collection sites was collected and a total of 864 samples were analyzed, of which 61.81 percent were classified as unacceptable. It was observed that 33 cities performed fluoridation but in 78.79 percent of these cities there were variations in the fluoride level among the sites and in the same site during the period of study. One can conclude that most of these cities do not control the fluoride levels in the public water, since fluoridation occurs in a discontinuous manner and in most of the situations not within the recommended concentrations.

Distribuição e tamanho populacional do papagaio-de-cara-roxa Amazona brasiliensis no estado de São Paulo

The Red-tailed Amazon Amazona brasiliensis is one of most threatened psitacid in the world. In the state of São Paulo, SE Brazil, it is restricted to a narrow coastal zone. The total population of A. brasiliensis has been estimated to be around 4,000 birds, but no detailed information is known for São Paulo. We studied the population status and mapped the distribution of A. brasiliensis in the state of São Paulo. Simultaneous censuses were carried out in three main islands (Cananéia, Ilha do Cardoso and Ilha Comprida) with A. brasiliensis populations in 2003 and 2004. We searched the parrots in an area of 1413.28 km2 and visited 69 sites. Amazona brasiliensis were recorded in 55 localities and 12 sleeping roosts. Our census estimated a population of at least 1,221 parrots in the stronghold of their distribution in the state of São Paulo. The highest number of parrots were recorded outside the main protected areas in the region (64% of the population), which may threaten the future of this population. Urban growing is the main threat for the population of São Paulo, and the creation of protected areas in Cananéia and Comprida island is critical for the future of the A. brasiliensis in the area.

Conclusion: Nevertheless the low prevalence rate of cicatricial trachoma in our region, to prevent trachoma blindness is the cicatrical form of the disease is very important to treat the trichiasis.

Avaliação da assistência pré-natal e puerperal desenvolvidas em região do interior do Estado de São Paulo em 2005

Objectives: to evaluate the structure and process of the prenatal and puerperal care given by Direção Regional de Saúde (DIR) XI, at the city of Botucatu, State of São Paulo, Brazil. Methods: an evaluation of resources and activities developed during prenatal and puerperal care in twenty municipalities comprising DIR XI which had adhered the Prenatal and Birth Humanization Program until 2003. Interviews with city managers and analysis of 385 sampled patient charts taking into account recommendations by the Health Department. Results: structure analysis showed that caregiving was centered on medical work; basic equipment and instruments were available; 85.2% of patients began prenatal care with up to 120 days of pregnancy, and 75.9% had at least six prenatal consultations. The active search for absentees and strategies for early prenatal care initiation were observed in 30% and 50% of the municipalities, respectively. Process indicators showed that 3.6% of women had six prenatal consultations, one puerperal consultation, all basic exams and tetanus immunization. Recording of gestational age, arterial blood pressure and weight was of approximately 90%; 58.7% of the women underwent childbirth review and 31.5% were vaccinated. Conclusions: the performance of the set of activities is a challenge to prenatal care at DIR XI.

Análise da evolução da paisagem no entorno da represa dos rios jaguari e jacareí, estado de são paulo, com base em sensoriamento remoto e SIG

The primary objective of this study is to evaluate by means of remote sensing and GIS, the landscape evolution around the Jaguari and Jacareí River Dam, located in the eastern section of the State of São Paulo, Brazil. For this purpose we used LANDSAT 5/YM and CBERS-2/CCD images from 1984/1985 and 2006, respectively, considering the following classes of land use: forest, cultivated forest, agriculture, urban areas and water bodies. The two selected dates reflect important changes in the region such as the installation of the dam and subsequent urbanization of parts of its margins and the enlargement of the Fernão Dias Federal Highway, which contributed to an increase of areas of anthropic activities in the studied region. The results also indicate an increase in areas covered by native and planted forests, thus confirming a similar trend in other areas of the State of São Paulo.

Categorização functional trófica das comunidades de macroinvertebrados de dois reservatórios na região centro-oeste do Estado de São Paulo, Brasil

The use of the concept of guild can be useful for the functional trophic categorization of communities, because there is no requirement identification of organisms in the level of species and not to treat each species as a separate entity. The aim of this study was to analyze the functional feeding groups (collectors-gatherers, collectors-filterers, shredders, predators and grazer-scrapers) of the macroinvertebrate communities of two reservoirs in the Midwestern region of São Paulo State. Sampling was carried out in rainy (March/April - 2001) and dry (July/August - 2001) seasons and the data obtained indicate that 'collectors-gatherers' is the most frequent guild. This fact suggests a great importance of organic matter as a food source in the diet of the macroinvertebrates analyzed.

Proposição e validações de equações para estimativa da erosividade de dois municípios do estado de São Paulo

The equations and extrapolation use to localities whose characteristics of soil and climate, even if partial, distinguish the town to which they were generated, still permeate in studies to estimate the rainfall erosivity (EI 30). This work has objective to propose and validate mathematical equations to estimate the rainfall erosivity of two cities of Sao Paulo State's. The adjusted to estimate obtaining and validate data of equations of erosivity (EI 30) according to values of coefficient of rain (Rc) were obtained from pluviographic and pluviometric rainfall data, respectively, using of distinct historical rainfall series. Mutiple comparisions test and confidence intervals were performed to compare absolute average of EI 30, pluviometric data (Pp), and Rc. The correlation between EI 30 and Rc was verified by of Pearson correlation coefficient. Test of the hypothesis of equality between population variance was used to compare the equations. Pluviometrics data of historical series rainfall data different than those that the models were generated were used to validate and to assess the performance of the equations, proposed of this study and compare them with another equation already consolidated in literature. The results show that for the conditions under which the study was conducted, the simple linear equations, shown to be the most appropriate to estimate the rainfall erosivity these two cities. According to the test of the hypothesis of equality variances between populations, the equations adjusted for each city differ statistically so that the rainfall erosivity of each city must be estimated by their respective equation.
