objectives: with side effects of antibiotics taken into consideration, the necessity of antibiotic therapy after simple implant placement procedures is still a subject of debate and the existing literature on this topic is widely controversial. the aim of this study was to assess the effect of postoperative amoxicillin therapy on early colonization of peri-implant sulcus after implant placement...

the objective of this research was to study the feasibility of a two stage continuous system employing anaerobic-aerobic microbial film for domestic wastewater treatment and the effect of iron on the behavior of sulfate reducing bacteria in anaerobic metabolism. a bench scale system with an anaerobic filter followed by aerobic fixed units used plastic media and was operated in up flow manner wi...

materials and methods one hundred ssis specimens were obtained by needle aspiration from purulent material in depth of infected site. these specimens were cultured and incubated in both aerobic and anaerobic condition. for detection of antibiotic susceptibility pattern in aerobic and anaerobic bacteria, we used disk diffusion, agar dilution, and e-test methods. results a total of 194 bacterial ...

Although the bacterial flora of the conjunctiva in children and adults has been studied, there has been no previous comparison between these two age groups of anaerobic as well as aerobic bacteria. Conjunctival cultures from 229 eyes of 144 uninfected subjects were analysed for aerobic, microaerophilic, and anaerobic bacteria. Adults showed a greater number of species per eye than did younger s...

Clinafloxacin was more active than ciprofloxacin against 4,213 aerobic and facultative anaerobic bacterial isolates from 10 medical centers, as tested by broth microdilution and disk diffusion methods. The percentage of 201 anaerobes susceptible to clinafloxacin by broth microdilution was comparable to cefoxitin. Our data support the proposed disk diffusion interpretive criteria for aerobic bac...

We report here the 5.19-Mb draft genome sequence of Bacillus galactosidilyticus PL133 isolated from poultry litter. The isolate was an important member of the cultivable aerobic bacteria identified to have ureolytic activity, which is responsible for ammonia generation in poultry litter residue.

We report the 2.7 Mb draft genome sequence of Staphylococcus sp. NA309 isolated from poultry litter. The isolate was a dominant member of the cultivable aerobic bacteria identified to have ureolytic activity, responsible for ammonia generation in poultry litter residue.

The genomic GC contents of both nitrogen-fixing and non-fixing members of eight genera of bacteria are investigated. Analysis by t-tests showed that in the two aerobic general investigated (Aquaspirillum and Vibrio) there is a significantly higher GC content in the nitrogen-fixing members of the genus than in those unable to fix nitrogen, whilst in aerobic genera there is either no GC bias, or ...
