Contexto tectônico dos granitóides neoproterozóicos da faixa de dobramentos paraguai, MS e MT

The Neoproterozoic Granitic Province from the southeast of Mato Grosso and Mato Grosso do Sul region is constituted by seven distinctive granitic bodies, emplaced in the epimetamorphic rocks of the Cuiabá Group and related to the evolution of Paraguai Folded Belt. The Northern portion crops out in Mato Grosso State and is constituted by São Vicente, Araguaiana and Lajinha batholiths; the Southern portion crops out in the Mato Grosso do Sul State and is represented the Sonora, Coxim Rio Negro and Taboco massifs. The structural evolution is evidenced by the presence of three deformational phases, the first one is characterized by axial planar foliation (S 1), parallel or sub parallel to S 0, with attitude N60E/70NW; the second constitutes the most important phase for the tectonic arrangement and is defined by a slaty and/or crenulation cleavages (S 2), with attitude N10W/30SW and contact metamorphism associated to the emplacement of granitic bodies, the third phase is characterized by a weak retrometamorphic cleavage (S 3) with attitude N10E/ 80NW, that evolves local and gradually to strike-slip shear zones. The geological data suggest that this province was formed syn- to post tectonic to the D2 deformational set associated to the end of the collisional event in the Southeastern of the Amazonian Craton.

First record of molluscs naturally infected with Angiostrongylus cantonensis (Chen, 1935) (Nematoda: Metastrongylidae) in Brazil

Seeking the identification of Angiostrongylus cantonensis as a potential etiological agent of three clinical cases of eosinophilic meningitis, mollusc specimens were collected in the state of Espírito Santo, Brazil. The snails were identified as Sarasinula marginata (45 specimens), Subulina octona (157), Achatina fulica (45) and Bradybaena similaris (23). Larvae obtained were submitted to polymerase chain reaction and restriction fragment length polymorphism diagnosis. Their genetic profile were corresponded to A. cantonensis. Rattus norvegicus experimentally infected with third-stage larvae, developed menigoencephalitis, and parasites became sexually mature in the lungs. Additionally, larvae obtained from A. fulica snails, from São Vicente, state of São Paulo, also showed genetic profiles of this nematode. This is the first record of Brazilian molluscs infected with this nematode species.

Ocorrência da Mosca-negra-dos-citros (Aleurocanthus woglumi ashby) (Hemiptera: aleyrodidae) em Pernâmbuco

This paper aimed to verify the presence of black-fly of citrus in the state of Pernambuco in Brazil and wordwide. The material with symptoms were collected in the metropolitan area of Recife/PE and subsequently led to the identification in the Insect Biology Laboratory of the Federal Rural University of Pernambuco - UFRPE on February 4, 2011. The samples collected from the branches of citrus and bilocular, found the presence of eggs, nymphs, "pupae" and adults of Aleurocanthus woglumi, confirming its occurrence in the state of Pernambuco. The presence of blackfly of citrus had been detected in the city in the state of Pernambuco as Timbauba, Bom Jardim, Macaparana, Axes, Orobo, Sao Vincent Farrer and Itambe in citrus plants. Before that had a suspect in the Valley Siriji/PE, now it is in the metropolitan area of Recife, therefore we can confirm that the material collected and identified in the metropolitan area of Pernambuco is A. woglumi.

Bacterial contamination of the catfish (Cathorops agassizii - Valenciennes, 1839 and Genidens genidens - Agassiz, 1829) sting

This work aimed to study the bacterial contamination in stings of the catfish Genidens genidens and Cathorops agassizii found in the São Vicente estuarine system (São Paulo State, Brazil). For bacteriological analyses, we used fish samples distributed into a group of 50 specimens (25 C. agassizii and 25 G. genidens) and a group of 14 specimens (7 C. agassizii and 7 G. genidens). Results showed contamination of 13 different bacterial species of Enterobacteriaceae, being Klebsiella pneumoniae the most frequent bacteria (26.80%) followed by Enterobacter sp and Escherichia coli (16.27%), and Serratia marcescens, Serratia sp. and Proteus mirabilis (1.16%). Gram-positive bacteria as well as fungi were not detected in the samples. According to the Gram-negative species characterized and with regard to the environmental conditions, it can also be considered that accidents with these catfish stings may develop significant acute secondary infections in humans.

Caracterização microbiológica do veneno do ferrão do Bagre (Cathorops agassizii and Genidens genidens)

This work aimed to study the bacterial contamination of the catfishes stings Genidens genidens (Valenciennes, 1839); and Cathorops agassizii (Agassiz, 1829) found in the estuary-bay complex of Santos and São Vicente (São Paulo State). Fish samples for bacteriological analyses were obtained and constituted of a group of 50 specimens, being 25 of Cathorops agassizii and 25 of Genidens genidens,. The bacteriological analyses showed that there was contamination of the stings by 13 different strains of Enterobacteriaceae with Klebsiella pneumoniae (26,80%) as the most frequent bacteria and lower percentual frequencies for Enterobacter sp and Escherichia coli (16,27%) and Serratia marcescens, Serratia sp. and Proteus mirabilis (1,16%). Gram positive bacteria, as well fungi species were not detected in the samples. In basis of the Gram negative species characterized, is possible to consider the bacterial strains are representative of the environmental public health conditions, as well as, accidents with these fish stings are able to develop significative acute secondary infections in humans.

Os granitóides brasilianos da faixa de dobramentos paraguai, MS e MT

The Brazilian Granitic Province from southeastern Mato Grosso do Sul and Mato Grosso region, central western Brazil, can be divided into two major groups and/or magmatic events related to the evolution of the Paraguay Fold Belt. The southern portion crops out in Mato Grosso do Sul State and is constituted by the Taboco, Rio Negro, Coxim and Sonora massifs forming NE-SW oriented, elongated small intrusions. The north portion crops out in Mato Grosso State and is constituted by the São Vicente, Araguaiana and Lajinha batholiths. Lithogeochemical aspects of the northern granites point to Type-I granites ranging from K calc-alkaline to high-K, peraluminous to metaluminous in composition, generated in an environment of continental collision and/or post- collision decompression. The southern granites are Type-I, from K calc-alkaline to high-K, peraluminous to subordinate metalummous, in a syn-collision continental arc environment with the exception of some pre-collisional facies from the Rio Negro Massif. The southern granites have less SiO 2 and K 2O, and are less differentiated and evolved than granites from the northern region. The four southern granites can be grouped into two subordinate sets with the degree of differentiation increasing from South (Taboco and Rio Negro) to North (Coxim and Sonora). The granitic rocks are characterized by a magmatism generated by melting of material from the lower crust which suggests that in this province the formation from non-cogenetic magmas with diversified compositions and distinct degrees of fractioning reaching more steady consolidated environments at the end of the collisional event in the southeastern Amazonian Craton.

Influence of seasonality and pollution on the hematological parameters of the estuarine fish Centropomus parallelus

This study investigated the hematological parameters of the tropical estuarine fish Centropomus parallelus and their use as a non-destructive biomarker for aquatic pollution. Individuals were collected, in summer and winter, at two estuaries, Cananéia (CAN) and São Vicente (SVE), and blood was extracted by caudal puncture. The evaluated parameters were hematocrit (Ht), red blood cells (RBC), Mean Corpuscular Volume (MCV), and the leukocyte (WBC) and thrombocyte counts. Fishes from CAN showed higher values of absolute number of thrombocytes in the summer. The fishes from SVE presented lower values of Ht and MCV in winter. Comparing the hematological parameters of fishes from these two sites, Ht, MCV, WBC and RBC were higher in fishes from SVE in the summer, whereas during the winter, Ht and thrombocytes were higher in animals from SVE. The results allow attributing the changes in the blood of fishes to seasonality and the presence of contaminants.
