Ocorrência de parasitos gastrintestinais em amostras fecais de felinos no município de Andradina, São Paulo

The purpose of this study was to verify the occurrence of gastrointestinal parasites in fecal samples from cats of the Andradina city, SP. This work was carried out from March to November of 2007, and used 51 cats delivered to the Center of Zoonoses Control of that city. Techniques of Willis and Faust were used in the fecal examination and resulted in detection of Ancylostoma spp. in 96.1% of the animals; Toxocara spp. in 43.1%; Cystoisospora spp. in 43.1%; Dipylidium caninum in 21.6% and Giardia spp. in 5.9% samples. Cryptosporidium spp. oocysts were detected in 3.9% fecal samples by the use of malachite green negative stain. There was no significant association between the occurrence of endoparasites and consistency of fecal samples. The results confirm that these cats represent important hosts of parasites, some of those with high zoonotic potential.

Prevalência de oclusopatias e comparação entre a Classificação de Angle e o Índice de Estética Dentária em escolares do interior do estado de São Paulo - Brasil

INTRODUÇÃO: as oclusopatias estão entre os principais problemas de saúde bucal em todo o mundo, juntamente com a cárie dentária e a doença periodontal, e vários índices têm sido utilizados para registrá-las. OBJETIVOS: verificar a prevalência de oclusopatias utilizando a Classificação de Angle e o Índice de Estética Dentária (DAI), sua severidade e a necessidade de tratamento ortodôntico registradas pelo DAI, e comparar os resultados de ambos os índices, visando correlacionar o padrão dos dados coletados e a viabilidade de utilizá-los de forma conjunta. MÉTODOS: a amostra consistiu de 734 escolares com idade de 12 anos, de ambos os sexos, da rede pública do município de Lins/SP. Foram realizados exames nos pátios das escolas com utilização de sondas IPC a olho nu. RESULTADOS: pela Classificação de Angle, encontrou-se 33,24% das crianças com oclusão normal e 66,76% com má oclusão. Pelo DAI, observou-se que 65,26% das crianças apresentavam-se sem anormalidades ou com más oclusões leves. A má oclusão definida esteve presente em 12,81%, a má oclusão severa foi observada em 10,90% e a muito severa ou incapacitante em 11,03%. A maioria das crianças (70,57%) apresentou relação molar normal, e o overjet maxilar anterior foi a alteração mais frequentemente observada. No cruzamento dos índices houve semelhanças e divergências. CONCLUSÃO: o DAI não foi sensível a alguns problemas de oclusão detectados pela Classificação de Angle, e a recíproca foi verdadeira, demonstrando que ambos os índices possuem pontos distintos na detecção das oclusopatias, podendo ser utilizados de forma reciprocamente complementar.

Peso ao nascer e padrões de atendimento ao parto em município do Estado de São Paulo, Brasil, 1986

Foram estudados 4.776 recém-nascidos nos hospitais de Araraquara, SP (Brasil), durante o ano de 1986 para analisar sua distribuição quanto ao peso ao nascer, tipo de parto e categoria de internação. A incidência de baixo peso ao nascer foi de 9,2%. Quanto ao tipo de parto, a proporção de cesáreas foi a maior, com 76,0% do total de partos. Na associação do tipo de parto com a categoria de internação, a incidência de cesáreas entre as parturientes com assistência médica gratuita foi de 44,0% e entre as de assistência particular foi de 92,4%. A maior proporção de recém-nascidos com baixo peso ao nascer foi observada em parturientes com assistência gratuita, 10,8% seguida das previdenciárias, com 9,8% e particulares, 5,6%.

Short report: Application of an alternative Aedes species (Diptera : Culicidae) surveillance method in Botucatu City, São Paulo, Brazil

One of the main problems with dengue is the control of Aedes aegypti, its major vector. In Brazil, the current control program for Ae. aegypti and Aedes albopictus populations includes larval density surveys. An interesting alternative is the use of a distinct index, the Premise Condition Index (PCI). This tool relates conditions of property, such as houses and yards, and the degree of shade with the occurrence of Aedes sp. oviposition, and is calculated as scores from 3 to 9. The lowest score indicates property in good condition and an unfavorable breeding environment, while the highest score indicates property at high risk for infestation by Aedes sp. The present study is based on the application of the PCI in an urban area of Botucatu, Brazil to confirm its effectiveness.

Helminths of toad Rhinella icterica (Bufonidae), from the municipality of Botucatu, São Paulo State, Brazil.

Fifteen specimens of bufonid toad Rhinella icterica (Spix, 1824), 7 males and 8 females, collected in the municipality of Botucatu, São Paulo State, Brazil, from March 2002 to January 2003, were examined for helminth parasites. All toads were infected with at least one parasite species (overall prevalence = 100%). Five helminth species were found, including four nematode species, Rhabdias fuelleborni Travassos, 1926, Oswaldocruzia subauricularis (Rudolphi, 1819), gen. sp. no identified Cosmocercidae Travassos, 1925 and larvae of Physaloptera Rudolphi, 1819, and one acanthocephalan species, Acanthocephalus saopaulensis Smales, 2007. Rhabdias fuelleborni and A. saopaulensis were the most abundant species. Except for Physalopteridae larvae, all helminths occur in high prevalence (> 70%). All helminth species presented a distribution toward to more aggregated pattern in these host samples.

NEW HOSTS and DISTRIBUTION RECORDS FOR NEMATODE PARASITES of FRESHWATER FISHES FROM São Paulo STATE, BRAZIL.

(Spirocamallanus) saofranciscensis in Acestrorhynchus lacustris; Contracaecum sp. (larvae), Guyanema sp., Hysterothylacium sp. (larvae) and Icthyouris sp. in Cyphocharax modestus; Contracaecum sp. (larvae), Cosmoxynemoides aguirrei and Pharyngodonidae gen. sp. in C. nagelii; Dioctophyma renale (larvae), Hysterothylacium sp. (larvae) and Rhabdochona sp. in Gymnotus sylvius; Capillariidae gen. sp. in Hoplosternum littorale; Cosmoxynema vianai, Guyanema sp., Ichthyouris sp. and Travnema travnema in Steindachnerina insculpta; Contracaecum sp. (larvae), Procamallanus (Spirocamallanus) rebecae (larvae) in Triportheus angulatus and Rhabdochona acuminata in Triportheus nematurus. This is first study of nematode parasites from the Peixe River, therefore all the species found are new geographical records and 19 are new host records.

Ecological distribution and reproductive period of the hermit crab Loxopagurus loxochelis (Anomura, Diogenidae) on the northern coast of São Paulo State, Brazil

The present study aimed to determine the ecological distribution of Loxopagurus loxochelis as a function of selected environmental factors, as well as its reproductive period based on the combined analysis of the presence of ovigerous females and the development of the gonad. The collections were carried out monthly from January to December 2000 in the region of Ubatuba (SP), using a fishing boat equipped with two double rig nets, in isobaths of 5, 10, 15, 20, 25, 30, 35 and 40 m, at which depths samples of sediment and water were collected. The cephalothoracic shield length and sex of the animals were determined; the abdomen was dissected to verify gonad development stages. A total of 334 individuals was obtained ( 196 males, 48 ovigerous females and 90 non-ovigerous females) with sizes varying from 3.0 to 8.6 mm (5.7 +/- 1.0 mm). A greater abundance of L. loxochelis (95.2%) was observed at depths of 20 and 25 m. These sites mainly revealed a substratum stable with a very fine sand fraction, which facilitates the habit of embedding shown by this hermit. With regard to gonadal analysis, it was possible to classify four gonad development stages for each sex: immature, rudimentary, developing and developed. It was observed that in the winter months about 71% of the females had gonads either developing or developed and 67% were ovigerous. Therefore, the winter period can be considered the peak of reproduction for this species, characterizing a typical seasonal-continuous reproduction.

Patterns of shell utilization in Petrochirus diogenes (Decapoda, Anomura, Diogenidae) in the Ubatuba region, São Paulo, Brazil

The objective of this study is to investigate the patterns of shell utilization in Petrochirus diogenes in the Ubatuba region, SP, Brazil. Hermit crabs were obtained from 1993 to 1996 with the aid of a shrimp fishery boat equipped with two double-rigged trawling nets. Shells were identified and weighed, and their maximum aperture width was measured. Hermit crabs were weighed, and their shield length was recorded. A total of 634 P. diogenes specimens, occupying shells of 12 gastropod species, was obtained. The shells of Tonna galea, Zidona dufresnei and Strombus pugilis were the most frequently occupied, the first marked by its larger aperture width and lower average weight. Small hermit crabs inhabited a wide variety of gastropod shells due to their higher availability. However, the utilization of T. galea shells became predominant as the crabs attained larger sizes. Differences in weight and aperture width are known to encourage certain shell utilization patterns and may affect growth and reproduction of hermit crabs.

Anurofauna em área de cerrado aberto no município de Borebi, estado de São Paulo, Sudeste do Brasil: uso do habitat, abundância e variação sazonal

O bioma Cerrado encontra-se descaracterizado e menos de três por cento de suas áreas originais está legalmente protegida. A anurofauna desse bioma não é muito rica quando comparado a outros biomas, porém há um grande número de espécies endêmicas. Aqui apresentamos uma lista de espécies de anuros registrados em uma lagoa em área de cerrado aberto do município de Borebi, região Centro-Oeste do estado de São Paulo, sudeste do Brasil. Durante 24 meses de estudo (2008 e 2009) caracterizamos a distribuição das espécies na lagoa estudada e descrevemos a variação sazonal das espécies. Foram registradas 27 espécies pertencentes a seis famílias: Bufonidae (duas espécies), Cycloramphidae (uma espécie), Hylidae (13 espécies), Leiuperidae (quatro espécies), Leptodactylidae (cinco espécies) e Microhylidae (duas espécies). A riqueza de espécies e abundância estiveram relacionadas com a precipitação. Dendropsophus minutus foi a espécie mais abundante e com registro de vocalização durante o ano inteiro. Rhinella ornata e Odontophrynus americanus foram restritas ao período seco e frio (abril a agosto). As outras espécies tiveram seu período de maior atividade nos meses chuvosos e quentes (setembro a março). A ocupação da lagoa variou com o tipo de vegetação e conforme a variação do seu volume de água, principalmente nos período de estiagem. A alta riqueza e abundância de anuros da lagoa pode ser resultado da ausência de peixes predadores, dos diversos tipos de microambientes do local e da ausência de outros corpos d'água próximos.

Contextualização da pesca mundial de lagostas e características de comercialização de Scyllarides spp. E Panulirus spp. na Baixada Santista, estado de São Paulo, Brasil

This study aimed to contextualize the world's lobster fishing and identify the characteristics of their trades in Santos region (SP). For this purpose, were realized surveys about the captures of 56 years referring the families traded in the world through the informations supplied by the FAO (Food and Agriculture Organization). To State of São Paulo, consults were made in the data base Propesq (Fishing Institute) about the fishing and prices. Besides interviews in fishmonger, businessmen of fishing and restaurant, we observed the trade and the economical potential compared the lobsters Scyllarides spp. and Panulirus spp. The worldwide the family Nephropidae is the one that has been presenting bigger growth in the captures from 1950 and the one that has the biggest observed captures, the Palinuridae showed a little growth of the captures up to the 80' years, and leaving from there it is oscillating without many expressive changes; Scyllarides began to stand out as fisheries only 70' in Asia, precisely where the other two Families had low catches proportional. In the State of São Paulo, two types of lobsters are sold in Baixada Santista, with conspicuous differences in prices between them. There is also a difference in the flow of trade in relation to active fishing gear. Traders notice a decrease in both abundance and size of individuals of both genders and a clear preference to sell the slippers lobsters (Scyllarides spp.) both for the quality of meat as the lowest price.
