ABSTRACT
Analysis of bacterial diversity in soils along the banks of the Solimões and Negro rivers, state of Amazonas, Brazil, was by partial sequencing of the genes codifying the rDNA16S region. Diversity of operational taxonomic units (OTU) and of the divergent sequences obtained were applied in comparative analysis of microbiological diversity in the two environments, based on richness estimators and OTU diversity indices. The higher OTU diversity in the Solimões was based on the higher number of parameters that evoke this. The interaction between the nucleotide sequences of bacteria inhabiting the two riverine environments indicated that the two microrganism communities are similar in composition.

Pacientes com insuficiência renal crônica apresentam um alto índice de alterações sistêmicas, e a presença dedano renal afeta significativamente o diagnóstico e a conduta terapêutica. A perda das funções regulatória eexcretória dos rins causa manifestações orais e múltiplas complicações os quais têm implicações no tratamentoodontológico. Os cuidados odontológicos nesses pacientes podem ser complexos devido à condição sistêmicaque resulta da função renal inadequada. Desta forma, o cirurgião-dentista deve estar familiarizado com acomplexidade desse grupo de pacientes. A manutenção da saúde oral é muito importante, uma vez que essespacientes são candidatos em potencial ao transplante renal.
Patients with chronic renal failure present a high number of systemic alterations which greatly affect diagnosis and therapeutic measures. The loss of the regulatory and excretory functions of the kidneys causes oral manifestations and multiple complications which carry implications in dental care. The latter may become very complex on account of the medical conditions that result from inadequately functioning kidneys. Therefore,the maintenance of these patients' oral health is very important since they are potential candidates to renal transplantation.
