Abstract

Marburg virus (MARV) nucleic acid was detected in Rousettus aegyptiacus bats in 2005 and 2006 in the midwest and southeast of Gabon. In this study we used MARV-specific real-time reverse-transcription polyermase chain reaction (RT-PCR) and MARV-specific nested RT-PCR assay to screen 1257 bats caught during July 2009, December 2009, and June 2010 in 3 caves situated in northern Gabon. Nine specimens tested positive by the real-time assay, with cycle threshold values ranging from 35 to 39, of which only 1 R. aegyptiacus specimen collected in 2009 was positive in the nested VP35 RT-PCR assay. Together with MARV-positive bats in the south and west found in 2005 and 2006, confirmation of phylogenetically closely related MARV-positive bats 5 years later and in northern Gabon suggests that MARV is now enzootic in Gabon and emphasizes the importance of long-term monitoring of bat populations and human-bat interfaces.

Abstract

Hepatitis C virus (HCV) is among the most relevant causes of liver cirrhosis and hepatocellular carcinoma. Research is complicated by a lack of accessible small animal models. The systematic investigation of viruses of small mammals could guide efforts to establish such models, while providing insight into viral evolutionary biology. We have assembled the so-far largest collection of small-mammal samples from around the world, qualified to be screened for bloodborne viruses, including sera and organs from 4,770 rodent

Abstract

Hepatitis C virus (HCV) is among the most relevant causes of liver cirrhosis and hepatocellular carcinoma. Research is complicated by a lack of accessible small animal models. The systematic investigation of viruses of small mammals could guide efforts to establish such models, while providing insight into viral evolutionary biology. We have assembled the so-far largest collection of small-mammal samples from around the world, qualified to be screened for bloodborne viruses, including sera and organs from 4,770 rodents (41 species); and sera from 2,939 bats (51 species). Three highly divergent rodent hepacivirus clades were detected in 27 (1.8%) of 1,465 European bank voles (Myodes glareolus) and 10 (1.9%) of 518 South African four-striped mice (Rhabdomys pumilio). Bats showed anti-HCV immunoblot reactivities but no virus detection, although the genetic relatedness suggested by the serologic results should have enabled RNA detection using the broadly reactive PCR assays developed for this study. 210 horses and 858 cats and dogs were tested, yielding further horse-associated hepaciviruses but none in dogs or cats. The rodent viruses were equidistant to HCV, exceeding by far the diversity of HCV and the canine/equine hepaciviruses taken together. Five full genomes were sequenced, representing all viral lineages. Salient genome features and distance criteria supported classification of all viruses as hepaciviruses. Quantitative RT-PCR, RNA in-situ hybridisation, and histopathology suggested hepatic tropism with liver inflammation resembling hepatitis C. Recombinant serology for two distinct hepacivirus lineages in 97 bank voles identified seroprevalence rates of 8.3 and 12.4%, respectively. Antibodies in bank vole sera neither cross-reacted with HCV, nor the heterologous bank vole hepacivirus. Co-occurrence of RNA and antibodies was found in 3 of 57 PCR-positive bank vole sera (5.3%). Our data enable new hypotheses regarding HCV evolution and encourage efforts to devel

Abstract

At the moment, a 70MeV cyclotron is under construction by the IBA company. This cyclotron will be able to accelerate H- beam from a multicusp source and with a beam intensity in the range of 10mA at the source extraction. A He1+2+ beam is also required. This beam will be produced by a PANTECHNIK ECR ion source (SUPERNANOCAN) with an extracted current of 1 to 2mA. In this paper the studies and design of the two sources with a common axial injection in the cyclotron are described.

Abstract

The monitoring of ecosystem processes and states is a critical step in the management of protected areas. It allows for the assessment of the success or failure of practices ranging from ‘laissez-faire’ to strong hands-on policies. Much effort is for instance devoted to the monitoring of wildlife abundance, particularly when associated with large ecological influence or socio-economical values (Gordon, Hester & Festa-Bianchet, 2004). In Africa, the diversity of large herbivores represents both a major asset of protected areas and a global conservation target as a consequence of the dramatic decline of wildlife populations under other land uses. In addition to the local importance of such monitoring data, collation of data from multiple sites ultimately allows general patterns to be revealed (e.g. Fritz & Duncan, 1994). Here, we contribute to the general knowledge on large African herbivores by reporting on their seasonal abundance, using road transect counts, in Hwange National Park (thereafter HNP), north-western Zimbabwe.
