1. Isoenzymatic genotyping of Staphylococcus aureus from dairy cattle and human clinical environments reveal evolutionary divergences
ABSTRACT Background The genetic variability of 610 S. aureus isolates from the hands of professional dentists (A), dental clinic environment air (B), bovine milk from cows with and without mastitis (C), an insufflator for milking equipment (D) and milking environment air (E) was studied by isoenzyme genotyping and genetic and cluster analysis. Results Mo

2. In silico analysis of amino acid variation in human respiratory syncytial virus: insights into immunodiagnostics
BACKGROUND The highly contagious nature of human respiratory syncytial virus (HRSV) and the gravity of its infection in newborns and vulnerable adults pose a serious public health problem. Thus, a rapid and sensitive diagnostic test for viral detection that can be implemented upon the first appearance of symptoms is needed. The genetic variation of the vir

3. Diversidade em Psidium guajava L. por caracteres morfológicos, moleculares e citogenéticos / Diversity in Psidium guajava L. by morphological, molecular and cytogenetics
Guava (Psidium guajava L.) is one of the most economically important fruit crop from Myrtaceae family. Brazil is one of the largest producers of guava in the world, which is a potential crop in growth and profitability. Cross-pollination of the species and the existence of heterogeneous seminal propagation orchards result in variability, allowing the selecti

4. Caracterização da diversidade genética de Teca (Tectona grandis) de diferentes procedências usando marcadores microssatélites / Characterization of genetic diversity of teak (Tectona grandis) from different provenances using microsatelliate markes
Teak (Tectona grandis) is one of the main timber species in the world with high economic value, famous for its beauty, strength and durability. The species occurs naturally in India, Myanmar, Thailand, Laos and Indonesia, where diversity studies have been conducted with regard to the conservation of genetic resources. However, there is a need for studies of

5. Usos tradicionais e manejo incipiente de Spondias tuberosa Arruda no Semi-Árido do Nordeste do Brasil
The people select edible plants for the attendance its economic, social and cultural necessities, being such action responsible human being for modification genetic and fenotipics, being such evolutive process called domestication. The present study has for aim to study the influence of practice of collection and management on the populations of Spondias tub

6. Estrutura genética e fenóis totais de populações naturais de barbatimão (Stryphnodendron adstringens) / Genetic structure and total phenols of the natural populations of barbatimão (Stryphnodendron adstringens)
Four natural populations of the Struphnodendron adstringens in the cerrado strictu sensu, North region of Minas Gerais State were studied, three from the Grão Mogol district and one from the Montes Claros district. Through the analyzes of 5 isoenzimatic polimorphic locos, estimates of the allelic frequencies of 276 adult individuals were obtained. Based on

7. Relationship of Maize Testers Selection and their Genetic Divergences / Relações entre seleção de testadores de milho e suas divergências genéticas
The objectives of this study were to relate the magnitudes of the correlation between testcrosses with the genetic divergences of the testers in order to verify if the genetic similarity of the testers could allow the reduction of testers, and if the level of selection intensity that should be applied is also a function of the genetic similarity of the teste

8. Estudos de diversidade genética em estoques reprodutores de camarões Litopenaeus vannamei cultivados no Brasil.
The identification of genetic marks can provide information about the distribution of genetic variability in relation to populational size and parental generation, besides the discrimination of lines and/or individuals. Researches carried out in different shrimp species reared at captivity have demonstrated that a regular monitoring of the genetic variabilit

9. Evaluation of genetic divergence of borrelial isolates from Lyme disease patients in Hokkaido, Japan, by rRNA gene probes.
Eight spirochetal isolates (JEM1 to JEM8) were obtained from cutaneous lesions of patients with Lyme disease in Hokkaido, Japan, and were analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, reactivities with monoclonal and polyclonal antibodies, and Southern blot hybridization. The protein profiles of these borrelial isolates were variable

10. Lack of phylogeography in European mammals before the last glaciation
In many extant animal and plant species in Europe and North America a correlation exists between the geographical location of individuals and the genetic relatedness of the mitochondrial (mt) DNA sequences that they carry. Here, we analyze mtDNA sequences from cave bears, brown bears, cave hyenas, and Neandertals in Europe before the last glacial maximum and

11. Evolutionary Relationships among Five Subspecies of MUS MUSCULUS Based on Restriction Enzyme Cleavage Patterns of Mitochondrial DNA
The intra- and intersubspecific genetic distances between five subspecies of Mus musculus were estimated from restriction enzyme cleavage patterns or maps of mitochondrial DNA (mtDNA). The European subspecies, M. m. domesticus and Asian subspecies, M. m. bactrianus, M. m. castaneus, M. m. molossinus and M. m. urbanus were examined. For each subspecies, excep

12. Genomic Divergences between Humans and Other Hominoids and the Effective Population Size of the Common Ancestor of Humans and Chimpanzees
To study the genomic divergences among hominoids and to estimate the effective population size of the common ancestor of humans and chimpanzees, we selected 53 autosomal intergenic nonrepetitive DNA segments from the human genome and sequenced them in a human, a chimpanzee, a gorilla, and an orangutan. The average sequence divergence was only 1.24% ± 0.07%
