However, in the phylogram based on 5.8S-ITS2 sequences (Figure 3), these two specimens constitute a highly supported clade (PP = 1.00) separate from the clade that includes the H. setigerum complex.
But as herbarium specimens constitute an invaluable resource for the study of genetic diversity of plants, algae and fungi, several comparative studies have addressed the problem of extracting DNA from herbarium specimens.
A first derivation step from a taxon-specific field unit is the individualization of specimens, the specimen thus constitutes a first derivative of the field unit.
In general, limited availability of samples of known origin, or reversely the lack of the information on the true origin of available specimens, constitutes the main drawback of the proposed approach.
Thus, the isolation of P. aeruginosa from blood cultures, as well as respiratory specimens, constitutes strong evidence of true Pseudomonas pneumonia.
Polymicrobial bacteremia identified in single blood specimens constituted on an average of 56% (range 40 to 75%) during the 16 year study period.
Each original description of a new animal species must designate at least one type specimen, which constitutes a physical specimen and not simply a digital image deposited in a permanent institutional collection or repository that is accessible to the scientific community.
A total of 61 breast tissue specimens constituted by fibroadenomas, hyperplastic adenosis/fibroadenomas, ductal carcinomas, lobular carcinomas and other breast carcinomas were collected at 307 Hospital (Beijing, China) from patients undergoing surgery (Table 1).
Both convex and concave configurations with a diverse curvature are considered for the specimens, constituted by four Portuguese bricks bonded by three joints of conventional mortar.
The 1802 variant specimens constitute 234 distinct types of genetic variants (i.e., with a distinct ompA mutational pattern that may be shared by several strains), for which no insertion/deletion or any trace of recombination event was found in ompA.
