Quantitative method for measurement of aerotolerance of bacteria and its application to oral indigenous anaerobes.
نویسندگان
چکیده
An index which expressed the aerobic to anaerobic potential was made for bacteria with intermediate tolerance for oxygen. One method used for this analysis was measurement of the relative bacterial growth ratio. The other method was based on the pattern of the absorbancy versus depth plot. The index was applied to oral indigenous anaerobes.

Role of oxyR in the oral anaerobe Porphyromonas gingivalis.
Porphyromonas gingivalis is an anaerobic microorganism that inhabits the oral cavity, where oxidative stress represents a constant challenge. A putative transcriptional regulator associated with oxidative stress, an oxyR homologue, is known from the P. gingivalis W83 genome sequence. We used microarrays to characterize the response of P. gingivalis to H2O2 and examine the role of oxyR in the re...
متن کاملQuantitative Bacterial Micro-Assay for Rapid Diagnosis of Galactosemia: Application in Galactosemia Neonatal Screening
In the present study a new economic and rapid bacterial micro-assay for simultaneous detection and quantitative measurement of serum galactose was developed. Analysis of the standard curve showed a linearity range for galactose from 2 mg/dL to 180 mg/dL with a regression equation of Y = 0.013X ? 0.083; R² = 0.962. The advantage of the method is its ability to measure serum galactose quantitativ...

SUMMARY During 2 years, 212 patients with PID and 160 women with no sign of PIO (as control group) were selected for the detection of aerobic an<l anaerobic bacteria and possible cause of the disease. Specimens from 58 patients and 60 controls were taken by laparoscopy and laparotomy, 154 patients and 100 controls by swabs from endocervical canal. From laparoscopy and laparotomy group(58) 9 ...

Background and Objective: The use of lactobacilli as probiotics requires the application of accurate and reliable methods for the detection and identification of bacteria at the strain level. Repetitive sequence-based polymerase chain reaction (rep-PCR), a DNA fingerprinting technique, has been successfully used as a powerful molecular typing method to determine taxonomic and phylogenetic relat...

Measurement systems analysis (MSA) has been applied in different aspect of industrial assessments to evaluate various types of quantitative and qualitative measures. Qualification of a measurement system depends on two important features: accuracy and precision. Since the capability of each quality system is severely related to the capability of its measurement system, the weakness of the two...
