DNA base sequence homologies among strains of Streptococcus sanguis.
DNA was isolated from 19 strains and substrains of Streptococcus sanguis and analysed for guanine plus cytosine (GC) contents and base sequence homologies. Three groups could be discerned: group 1 strains had 40-8 to 42-8 mol % GC; group 2, 42-7 to 44-0 mol % GC; group 3, 43-8 to 46-4 mol % GC. DNA homologies between groups 1 and 3 were 40 to 60% at 67 degrees C and 40% at 72 degrees C. The hom...
متن کاملInferring phylogenies from DNA sequences of unequal base compositions.
A new method for computing evolutionary distances between DNA sequences is proposed. Contrasting with classical methods, the underlying model does not assume that sequence base compositions (A, C, G, and T contents) are at equilibrium, thus allowing unequal base compositions among compared sequences. This makes the method more efficient than the usual ones in recovering phylogenetic trees from ...
متن کاملPrevalence of cdt Gene in Campylobacter jejuni Strains Isolated from Surface Waters of Rasht, Iran
ABSTRACT Background and Objective: Campylobacters are infectious zoonotic agents, and among the main bacterial causes of gastroenteritis in humans. Studies have shown that Campylobacter jejuni is of the main causes of infection among humans. Detection of these infectious agents in water resources is of great importance for maintaining the health of hu...
متن کاملUnzipping of DNA with correlated base sequence.
We consider force-induced unzipping transition for a heterogeneous DNA model with a correlated base sequence. Both finite-range and long-range correlated situations are considered. It is shown that finite-range correlations increase stability of DNA with respect to the external unzipping force. Due to long-range correlations the number of unzipped base pairs displays two widely different scenar...
متن کاملCampylobacter jejuni strains from patients with Guillain-Barré syndrome.
Campylobacter jejuni was isolated from stool cultures from 14 (30%) of 46 patients with Guillain-Barré syndrome and from 6 (1.2%) of 503 healthy persons, and the difference was highly significant (p < 0.0001). In addition, serological evidence of recent C. jejuni infection was found in 5 of 29 patients with negative stool cultures. Therefore, 41% of patients were associated with C. jejuni infec...
