ABSTRACT. The Pantanal basin seismic zone has experienced earthquakes with magnitudes up to 5.4 mb. New information on historical events was searched for in regional newspapers, especially the "Correio do Estado", Campo Grande, Mato Grosso do Sul State, Brazil. Several small new events, not previously reported in the Catalog of Berrocal et al. (1984), were discovered.  Five events had new macroseismic information from different localities allowing magnitudes to be estimated from the felt area. Ten new events were also discovered, each one felt in a single locality. The event of 1906-Oct-24, with previous magnitude 4.2, was felt in a larger area indicating magnitude 4.9 mb. The large event of 1919-June-01, reported in the Catalog with 4.9 mb, was false, and had resulted from joining a local tremor probably due to a meteorite fall in Santa Luzia (GO) with wrong interpretation of records of the RDJ station, Rio de Janeiro, as if they were from the same event in Mato Grosso. The revised catalog for the West-Central Brazil, compared with geophysical maps, shows that earthquakes occur in areas of low velocities in the upper mantle, as well as in areas of positive gravity free-air anomalies. Stress concentration in the upper crust can be explained as due to both lithospheric thinning and flexure.Keywords: historical seismicity, Pantanal, macroseismic information. Revisão da Sismicidade História do Centro-Oeste do Brasil: Novos Sismos Recém Descobertos e Implicações para Ameaça SísmicaRESUMO. A zona sísmica da bacia do Pantanal tem sismos até 5,4 mb. Informações mais detalhadas sobre eventos históricos foram pesquisadas em jornais regionais, especialmente o "Correio do Estado", Campo Grande, Mato Grosso do Sul. Vários pequenos eventos novos foram descobertos que não constavam do Catálogo anterior de Berrocal et al. (1984). Cinco eventos tiveram novas informações macrossísmicas de diferentes localidades, permitindo estimar magnitudes pela área afetada. Foram descobertos dez novos eventos, cada um com informações de uma única localidade. O evento de 24-Out-1906, com magnitude anterior 4,2, foi sentido em uma área maior, indicando magnitude de 4,9 mb. Já o grande evento de 01-Jun-1919, relatado no Catálogo com magnitude 4,9 mb, era falso, sendo resultado da junção de um tremor local, possivelmente devido à queda de um meteorito em Santa Luzia (GO), com interpretação errada dos registros da estação RDJ (Rio de Janeiro), como se fossem provenientes de um único evento em Mato Grosso. O catálogo revisado para a região Centro-Oeste do Brasil, comparado com mapas geofísicos, mostra que os sismos ocorrem em áreas de baixas velocidades no manto superior, bem como em áreas de anomalias ar-livre positivas. A concentração de tensões na crosta superior pode ser explicada tanto por afinamento litosférico, como por flexura.Palavras-chave: sismicidade histórica, Pantanal, informação macrossísmica.

Abstract Hemotropic mycoplasmas in dogs, such as Mycoplasma haemocanis, have been described worldwide. Recently, these pathogens have been reported to be causative agent of zoonosis. It is known that its transmission may occur through the action of blood-sucking arthropods (e.g. ticks or fleas), through blood transfusion, contaminated fomites and/or transplacentally. In Brazil, M. haemocanis is present in practically all regions and the tick Rhipicephalus sanguineus sensu lato is suspected the main vector. In the municipality of Campo Grande, state of Mato Grosso do Sul, there is little information about infection of dogs by M. haemocanis, or on the main epidemiological features associated with it. Thus, the aim of the present study was to determine the occurrence of M. haemocanis among dogs infested by ticks and to assess possible associations with some epidemiological factors. The polymerase chain reaction (PCR) and DNA sequencing were used to analyze dog blood samples (n = 94). DNA from M. haemocanis was detected in four samples. No significant associations were observed with any epidemiological parameter analyzed here. However, the results from this study confirm that this pathogen is circulating in this region and should be considered in the differential diagnosis of diseases among anemic dogs.

Abstract This study evaluated the parasite fauna of farmed hybrid surubim (Pseudoplatystoma reticulatum x P. corruscans) and the host-parasite-environment relationship in two fish farms located in Mato Grosso do Sul, Central Brazil, South America. A total of 120 hybrids from two different farms, 60 in each season (30 in the hot and 30 in cold season) were examined during a year. Water quality was weekly measured to evaluate the interaction among environmental conditions and parasitism. Histopathology was used to observe the effects of the parasites and environment on the fish gills. The ciliate protozoan Ichthyophthirius multifiliis and the monogeneans (Ameloblastella sp., Amphocleithrium paraguayensis, Vancleaveus ciccinus, V. fungulus and V. janacauensis) were the most prevalent parasites detected in both seasons in both farms, with prevalence above 80%. It was stated that parasites did not cause important damage in the health status of the hybrid surubim. These results might be related to general good management practices and environmental quality implemented by the fish farmers. The presence of uncommon monogenean parasites to this hybrid compared to their parents causing an environmental and ecological concern is here discussed.

A New Species

A new Hypoptopomatinae, Corumbataia britskii, is described based on specimens recently collected in a tributary of the upper Rio Paraná basin, Mato Grosso do Sul State, Brazil. Corumbataia britskii differs from its congeners by having a more depressed head profile (vs. a more rounded head profile in C. cuestae and C. tocantinensis), by having a more developed and conspicuous tuft of enlarged odontodes on the tip of the supraoccipital (vs. its reduced condition found in C. cuestae and C. tocantinensis), and by heaving a partially enclosed arrector fossae (vs. an almost completely enclosed arrector fossae in C. cuestae and C. tocantinensis).

Trichomycterus dali, new species, is described from flooded limestone caves in Serra da Bodoquena karst area, State of Mato Grosso do Sul, Central Brazil. The new species is diagnosed by a unique character in the genus, the presence of conspicuous, ridge-like adipose folds lining dorsally throughout the body. Trichomycterus dali can be further distinguished readily from epigean congeners by the reduction of eyes and skin pigmentation (except for T. gorgona), and from remaining congeners (i.e., all hypogean plus T. gorgona) by the total loss of eyes, not visible externally (except for T. sandovali and T. spelaeus). Other diagnostic features includes very long barbels, especially the nasal (99.3-143.5% HL) and the maxillary (97.0-131.3% HL), pectoral-fin ray count reaching I,9 and a unique cranial fontanel with a conspicuous constriction on the meeting point of supraoccipital and the two frontal bones. The troglobitic status of the species is suggested by the presence of troglomorphisms on an advanced degree, especially the reduction of skin pigmentation, the total loss of eyes and the enlarged barbels. In addition, the presence of a well developed adipose fold in adults may indicate a distinctive adaptation acquired by neoteny to withstand the food scarce conditions of its hypogean habitat.

Prey availability in an environment may change seasonally and these changes should be considered as determinant factors for the diets of anurans. Scinax species are generalist predators that feed on arthropods, but data concernning their diet in relation to prey availability are lacking. In this study, we describe the diet of Scinax fuscomarginatus by evaluating its possibly generalist diet related to prey availability in its environment. We studied the diet of Scinax fuscomarginatus by analysing the stomach contents of 48 individuals captured in the Campo Grande municipality, Mato Grosso do Sul state, Brazil. We found eight prey categories, the most common and most representative being Hemiptera. The selectivity index of the two most important prey varied inversely between dry and wet seasons. Prey availability also varied between seasons. These results suggest a temporal pattern in prey composition and in the diet of Scinax fuscomarginatus.

In order to determine the prevalence of hepatitis C virus (HCV) infection in quilombo remnant communities in Central Brazil, 1,007 subjects were interviewed in all 12 communities existing in Mato Grosso do Sul State, Central Brazil. Blood samples were collected and sera were tested for anti-HCV by enzyme-linked immunosorbent assay. Positive samples were retested for confirmation using a line immunoassay and were also subjected to HCV RNA detection. The prevalence of HCV infection was 0.2%. This finding shows a low prevalence of HCV infection in quilombo remnant communities in Central Brazil.
