The phrase "a date of isolation" is correct and usable in written English.
It can be used to refer to a specific date when someone or something was isolated, often in contexts related to health, research, or personal experiences.
Example: "The study began on a date of isolation, marking the start of the participants' quarantine period."
Alternatives: "a period of separation" or "a time of seclusion."
All 107 F. tularensis subsp. holarctica isolates showed the same fingerprint pattern by PFGE with the restriction enzyme XhoI, irrespective of their geographic origin, host, or date of isolation (isolate TU41 was not typeable by PFGE analysis).
We used the jModelTest program59 to select the best-fitting substitution model for our sequences according to the Bayesian information criterion, and the date of isolation of each isolate was used to calibrate the tree, and finally these analyses were performed using a log-normal relaxed molecular clock, which allows for different mutation rates on different branches.
These data were used to plot a linear regression curve against date of isolation of the strain.
A plot of the root-to-tip distance of the isolates within the PMEN2 clade relative to their date of isolation revealed a significant linear correlation (n = 168, R = 0.63, P value <2.2 × 10-16) that suggested a date of origin around 1967 [see Additional file 9: Figure S8A].
Surveillance laboratories upload raw sequence reads that are processed and added to a single tree that harbors all sequenced S. enterica isolates and associated metadata (date of isolation, isolation source, location, unique identifier).
Patient information such as age, sex, clinical presentation, isolated site and date of isolation are given in Table 1.
This conclusion is supported by the number of isolates recovered from HIV-positive patients (n=177), the age distribution, which peaks between 20 and 40 years of age, and the date of isolation with a peak corresponding to the 1990s.
MLST showed that, regardless of their geographic origin, date of isolation, or isolation source, chromosomal cpe isolates, i) assemble into one definitive cluster ii) lack pfoA and iii) lack a plasmid related to the cpe plasmid.
The date of isolation was the date a suspected case-patient was transported to an ETU.
From a comparison of MLVA type, geographic area, and date of isolation, it was concluded that what was originally thought to be 1 outbreak was actually caused by 2 different MLVA types (MLVA052 and MLVA056), which differed at loci STTR5 and STTR6 with 13 and 2 repeat units, respectively.
