Diversidade microbiana em infecções endodônticas primárias associadas ao traumatismo dentário

O presente trabalho tem por objetivo investigar a microbiota de canais radiculares, buscando a identificação e a quantificação destes microrganismos. Foram selecionados 31 dentes com infecção primária devido a traumatismo dentário. As amostras microbiológicas foram coletadas dos canais com o aux...

Avaliação clínica e microbiológica das técnicas de full mouth disinfection e raspagem e alisamento radicular associadas à azitromicina ou clorexidina no tratamento da periodontite crônica: ensaio clínico controlado randomizado

O tratamento não cirúrgico da doença periodontal inclui a realização de procedimentos de instrução de higiene oral e a raspagem e alisamento radicular por quadrantes (RAR). Com a finalidade de prevenir a rápida recolonização das bolsas periodontais por bactérias presentes em outros sítios int...

Campylobacter jejuni in commercial eggs

Braz. j. microbiol; 45 (1), 2014
This study evaluated the ability of Campylobacter jejuni to penetrate through the pores of the shells of commercial eggs and colonize the interior of these eggs, which may become a risk factor for human infection. Furthermore, this study assessed the survival and viability of the bacteria in commercial e...

Characterization of Escherichia coli virulence genes, pathotypes and antibiotic resistance properties in diarrheic calves in Iran

Biol. Res; 47 (), 2014
BACKGROUND: Calf diarrhea is a major economic concern in bovine industry all around the world. This study was carried out in order to investigate distribution of virulence genes, pathotypes, serogroups and antibiotic resistance properties of Escherichia coli isolated from diarrheic calves. RESULTS: Total...

The aim of this study was to isolate and characterize virulent strains of Cronobacter sakazakii from food samples of Bangladesh. RESULT: Six (6) Cronobacter sakazakii was isolated and identified from 54 food samples on the...

Acidobacteria appear to dominate the microbiome of two sympatric Caribbean Sponges and one Zoanthid

Biol. Res; 47 (), 2014
BACKGROUND: Marine invertebrate-associated microbial communities are interesting examples of complex symbiotic systems and are a potential source of biotechnological products. RESULTS: In this work, pyrosequencing-based assessment from bacterial community structures of sediments, two sponges, and one zoa...

Screening the antifungal activity of essential oils against decay fungi from palmyrah leaf handicrafts

Biol. Res; 47 (), 2014
BACKGROUND: The whitish tender leaves of Palmyrah are used for making handicrafts. The problem with these articles is discolouration with time and become more brittle due to fungal attack. This could be prevented by some protective coating. Instead of expensive and harmful chemicals we decided to test na...

Apoptosis in HEp-2 cells infected with Ureaplasma diversum

Biol. Res; 47 (), 2014
BACKGROUND: Bacterial pathogens have many strategies for infecting and persisting in host cells. Adhesion, invasion and intracellular life are important features in the biology of mollicutes. The intracellular location ofUreaplasma diversum may trigger disturbances in the host cell. This includes activat...
