2. Description of a human Bocavirus recombinant strain in the Americas
Human bocaviruses (HBoV) are mainly associated with respiratory and gastroenteric infections. These viruses belong to the family Parvoviridae, genus Bocaparvovirus and are classified in four subtypes (HBoV1-4). Recombination and point mutation have been described as basis of parvovirus evolution. In this study three viral sequences were obtained from positiv

3. Effect of probiotic Lactobacillus reuteri XC1 coexpressing endoglucanase and phytase on intestinal pH and morphology, carcass characteristics, meat quality, and serum biochemical indexes of broiler chickens
ABSTRACT This study investigated the effect of transformed Lactobacillys reuteri on intestinal pH and morphology, carcass characteristics, meat quality, and serum biochemical indexes of broiler chickens. A total of 480 broilers were assigned to six treatment groups and fed a phosphorus-adequate diet, a phosphorus-deficient diet, or a phosphorus-deficient die

4. An overview of the molecular and epidemiological features of HIV-1 infection in two major cities of Bahia state, Brazil
BACKGROUND The high mutation rate of the human immunodeficiency virus (HIV) has created a public health challenge because the use of antiretroviral drugs can generate selective pressure that drives resistance in these viruses. OBJECTIVE The aim of this work was to characterise the molecular and epidemiological profile of HIV in Bahia, Brazil. METHODS D

5. A glycoprotein E gene-deleted bovine herpesvirus 1 as a candidate vaccine strain
A bovine herpesvirus 1 (BoHV-1) defective in glycoprotein E (gE) was constructed from a Brazilian genital BoHV-1 isolate, by replacing the full gE coding region with the green fluorescent protein (GFP) gene for selection. Upon co-transfection of MDBK cells with genomic viral DNA plus the GFP-bearing gE-deletion plasmid, three fluorescent recombinant clones w

6. Protective microcirculatory and anti-inflammatory effects of heparin on endotoxemic hamsters
RESUMO OBJETIVO: Além de suas propriedades anticoagulantes, a heparina apresenta efeitos vasodilatadores e anti-inflamatórios que podem ajudar na reversão das alterações sépticas da microcirculação. Este artigo investiga os efeitos da heparina sobre alterações da microcirculação relacionadas com endotoxemia e compara-os com os observados com o u

8. Differential detection of transposable elements between Saccharum species
Cultivars of sugarcane (Saccharum) are hybrids between species S. officinarum (x = 10, 2n = 8x = 80) and S. spontaneum (x=8,2n=5-16x =40-128). These accessions have 100 to 130 chromosomes, 80-85% of which are derived from S. officinarum, 10-15% from S. spontaneum, and 5-10% are possible recombinants between the two genomes. The aim of this study was to analy

9. Cloning of a novel xylanase gene from a newly isolated Fusarium sp. Q7-31 and its expression in Escherichia coli
A strain of Q7-31 was isolated from Qinghai-Tibet Plateau and was identified as Fusarium sp. based on its morphological characteristics and ITS rDNA gene sequence analysis. It has the highest capacity of degrading cell wall activity compared with other 11 strains. To do research on its xylanase activity of Fusarium sp. Q7-31 while the degrading the rice cell

10. Determinantes virais envolvidos na adaptabilidade diferencial de dois begomovírus em tomateiro e Nicotiana benthamiana / Viral determinants involves in the differential adaptation of two begomovirus in tomato and Nicotiana benthamiana
Begomoviruses (family Geminiviridae) have a genome composed of a one or two components of circular, single-stranded DNA and infect dicotyledoneous plants. Symptoms induced by the begomovirus Tomato yellow spot virus (ToYSV) in tomato and Nicotiana benthamiana are more severe and appear earlier compared to those induced by Tomato rugose mosaic virus (ToRMV).

11. Caracterização biológica e molecular de recombinantes naturais de HIV-1. / Biological and molecular characterization of HIV-1 natural recombinants.
Recombination during reverse transcription is an important factor promoting HIV-1 diversity and adaptive change, allowing advantageous mutations arising on different genomes to undergo linkage in the same progeny recombinant genome more frequently than what would be expected under random mutation alone. In Brazil, several recombinant viruses were reported, a

12. Caracterização molecular de recombinantes intersubtipos do vírus da imunodeficiência humana tipo 1(HIV-1) em pacientes provenientes da epidemia do estado de São Paulo. / Molecular characterization of recombinant intersubtipos of human immunodeficiency virus type 1 (HIV-1) in patients from the epidemic in the state of Sao Paulo, Brazil.
The extensive HIV-1 genetic diversity has several implications on the viral adaptive and evolutionary capabilities. This diversity is due to intensive mutational rates derived from error-prone activity of viral reverse transcriptase and RNA genomic instability, generating a highly diverse and heterogeneous viral population named quasispecies. However, even t
