Caracterização genética do vírus da diarreia bovina detectada em bovinos do Sul de Minas Gerais, Brasil, persistentemente infectados

Isolates of bovine viral diarrhoea virus (BVDV) detected in serum samples of two persistently infected animals (PI) identified in a herd located in the southern state of Minas Gerais, Brazil, underwent genetic characterization trough partial nucleotide sequencing and analysis of the 5' Untranslated Region (5'UTR) of the viral genome. The isolates were characterized as belonging to genotype BVDV-1, subgenotype BVDV-1b. The results of this study suggest BVDV-1b as an agent of importance in the occurrence of bovine viral diarrhoea (BVD) in the herds of the region. Moreover, the genotypic characterization of isolates of BVDV helps to better understand the epidemiology of the disease, as the genetic variability of BVDV interferes in the serological tests and has implications for the use of vaccines, whose majority is produced only with reference strains of BVDV. Therefore, the investigation on the genetic diversity of BVDV existing in Brazil is required for the improvement of the disease prevention and control measures.

Forámenes emisarios del cráneo humano: Características anatómicas y sus relaciones con la neurocirugía clínica

The recognition of emissary foramens is important not only for understanding the regional neurovascular anatomy, but also to distinguish normal from potentially abnormal structures. Thus, the aim of this study was to review the literature on anatomical and clinical aspects of the mastoid, parietal and sphenoid emissary foramens. It was found that the emissary foramen presents importance in clinical practice because it acts as a route of spread of extracranial infection to the intracranial structures and also possible complications in neurosurgery, due to its influence in the performance of techniques such as radiofrequency rhizotomy for treatment of trigeminal neuralgia. The anatomical knowledge of the emissary foramens is important due to variability in their incidence in the human skull and its relation to the dura mater sinuses.

Co-infecção por vírus dengue, sorotipos 1 e 4, em paciente de cidade de porte médio no Brasil

The natural co-infection with dengue virus can occur in highly endemic areas where different serotypes have been observed for many years. We report one case of DENV-1/DENV-4 co-infection in human serum detected by molecular tests. Phylogenetic analysis of the sequences obtained indicated the presence of genotype V and II for DENV-1 and DENV-4, respectively.
