Three urban rabies outbreaks have been reported in Colombia during the last two decades, one of these is occurring in the Caribbean Region (northern Colombia), while the other two occurred almost simultaneously in Arauca (eastern Colombia) and in the Central Region and ended in 1997. In order to derive phylogenetic relationships between rabies viruses(More)
During the period 2000-2003, wild grey foxes (Urocyon cinereoargenteus) in northern Colombia became infected with rabies. In order to derive phylogenetic relationships between rabies viruses isolated in foxes, dogs and humans in this region, 902 nt cDNA fragments containing the G-L intergenic region and encoding the cytoplasmic domain of protein G and a(More)
OBJECTIVES A sylvatic rabies outbreak during March 2008 caused two human deaths in the town of Santander de Quilichao in Cauca, Colombia. This article describes the diagnostic laboratory techniques used, the field investigation and focus control used, as well as this outbreak's epidemiological significance and implications for public health. METHODS(More)
cDNA subtraction was employed to uncover differences in gene expression between myeloproliferative polycythaemia vera (PV) and normal haematopoietic precursors. Following cDNA subtraction using mRNAs isolated from PV and normal CD34+/CD33- bone-marrow cells, expression of the tumour suppressor H19 was found to be low or absent in the PV sample. Low levels(More)
Grapevine (Vitis vinifera L.) is one of the most important fruit crop worldwide. Commercial cultivars are greatly affected by a large number of pathogenic microorganisms that cause diseases during pre- and/or post-harvest periods, affecting production, processing and export, along with fruit quality. Among the potential threats, we can find bacteria, fungi,(More)
The cDNA and derived amino acid sequence of human diadenosine 5',5"'-P1,P4-tetraphosphate pyrophosphohydrolase have been determined with the aid of the GenBank Expressed Sequence Tag database. This enzyme possesses a modification of the MutT sequence motif found in certain nucleotide pyrophosphatases. It is unrelated to the enzymes of diadenosine(More)
Three urban rabies outbreaks have been reported in Colombia during the last two decades, one of which is ongoing in the Caribbean region (northern Colombia). The earlier outbreaks occurred almost simultaneously in Arauca (eastern Colombia) and in the Central region, ending in 1997. Phylogenetic relationships among rabies viruses isolated from the three(More)
