Abstract: Ecological alterations in the environment may have contributed significantly for the increase of nonhematophagous bats in urban perimeter. This migration has also brought the virus into the cities. This work aimed to describe rabies cases in bats caught from the urban areas of Campo Grande, Mato Gorsso do Sul – Center West Brazil. During the period of February the December of 2001,a total 526 bats were sent for rabies diagnosis. After the identification and classification of bats, fragments of brain, salivary gland and interscapular brown fat collected from each animal were submitted for direct fluorescent antibody (dFA) test and mouse inoculation test (MIT) for rabies diagnosis. Among the 526 sample examined, six (1.13%) were found positive for rabies by the both tests, and of theses, three belonged to insectivorous bats and the other three, frugivorous bats. Among the frugivorous bats, one was identified as the Artibeus fimbriatus. The presence of this species had never been reported in the city of Campo Grande, and this is also the first report of rabies in this species in our country. Altera es ecológicas nos ecossistemas silvestres tem contribuído significativamente para o aumento das col nias de morcegos n o hematófagos no perímetro urbano. O presente trabalho tem por objetivo, descrever casos de raiva em morcegos n o hematófagos no perímetro urbano de Campo Grande-MS, Brasil. No período de fevereiro a dezembro de 2001, foram estudados 526 morcegos n o hematófagos. Amostras de sangue foram e tecido, de cada animal, que foram submetidas as provas de imunofluorescência direta (IFD) e prova biológica (inocula o em camundongos), para pesquisa do vírus rábico. De todas amostras examinadas, seis foram positivas para o vírus da raivas (1,13%), sendo três de morcegos frugívoros e três de insetívoros. Entre os morcegos frugívoros identificados, registra-se o Artibeus fimbriatus, sendo a primeira descri o desta espécie na cidade de Campo Grande e o primeiro caso de raiva citado na literatura científica nesta espécie, no Brasil.

Revista Brasileira de Zoologia , 2004, DOI: 10.1590/S0101-81752004000300026
Abstract: this paper describes and analyzes the causes of dental formula anomalies in the bats artibeus lituratus (olfers, 1818) and artibeus fimbriatus gray, 1838 (phyllostomidae) belonging to populations inhabiting the southernmost brazilian state of rio grande do sul. based on material examined and descriptions reported in the literature, is presented a general discussion on variation in the presence or absence of the third superior and inferior molars within members of the genus artibeus (leach, 1821). of the 104 a. lituratus skulls examined was found one with an extra upper incisor and one with an extra upper right third molar, along with one case of lower third molar agenesis. in the 44 a. fimbriatus skulls examined was found one with an extra upper right second premolar, a tooth which is usually absent in this species. the occurrence of the extra molar in a. lituratus and the second premolar in a. fimbriatus are atavistic, probably reflecting the ancestral a. lituratus in the case of the extra molar and, for the premolar, an even more ancient ancestor which lived before the divergence of the phyllostomidae family. regarding the genus as a whole, there is variation in the presence or absence of the third superior molar in practically all artibeus species, such variation occurring at both the intrapopulational level and geographically. there is also already a low frequency of absent third inferior molars in various artibeus species. both superior and inferior third molars are in the process of exclusion from the dentition of artibeus and do not occur in some species, and, when present, are always reduced in size and extremely simplified in their cuspidal pattern and do not participate in food processing: indicating a clear evolutionary trend to the loss of these teeth. such variation is important because variability in the presence and absence of third molars means that these teeth are not appropriate characteristic for the identification of artibeus species.

Abstract: The genus Artibeus represents a highly diverse group of bats from the Neotropical region, with four large species occurring in Brazil. In this paper, a comparative cytogenetic study was carried out on the species Artibeus obscurus Schinz, 1821, A. fimbriatus Gray, 1838, A. lituratus Olfers, 1818 and A. planirostris Spix, 1823 that live sympatrically in the northeast of Brazil, through C-banding, silver staining and DNA-specific fluorochromes (CMA3 and DAPI). All the species had karyotypes with 2n=30,XX and 2n=31,XY1Y2, and FN=56. C-banding showed constitutive heterochromatin (CH) blocks in the pericentromeric regions of all the chromosomes and small CH blocks at the terminal region of pairs 5, 6, and 7 for all species. Notably, our C-banding data revealed species-specific autosomic CH blocks for each taxon, as well as different heterochromatic constitution of Y2 chromosomes of A. planirostris. Ag-NORs were observed in the short arms of chromosomes 5, 6 and 7 in all species. The sequential staining AgNO3/CMA3/DA/DAPI indicated a positive association of CH with Ag-NORs and positive CMA3 signals, thus reflecting GC-richness in these regions in A. obscurus and A. fimbriatus. In this work it was possible to identify interespecific divergences in the Brazilian large Artibeus species using C-banding it was possible provided a suitable tool in the cytotaxonomic differentiation of this genus.

Abstract: the influences of relief, precipitation, temperature, and seasonally was evaluated on the cattle rabies spatial distribution in the state of s?o paulo. in that way, a geographic data bank was developed in order to create a kernel function with the cases of cattle rabies from 1992 to 2003 and its relation with other variables. results showed that the rainy hilly areas with low temperature in the "planalto atlantico" and "província costeira" were linked to areas with the higher density of the function in opposite to the plane areas of the "planalto ocidental" with low rainy index and high temperatures. there were no relations between seasonality and cattle rabies in the state of s?o paulo. the flat region of the "depress?o periférica" and urban area between s?o paulo and campinas are barriers that determine the disease occurrence in east-west and east-south regions of the state.
