Streptococcus faecalis sex pheromone (cAD1) response: Evidence that the peptide inhibitor excreted by pAD1-containing cells may be plasmid determined
(Elsevier, 1987-01)
Streptococcus faecalis strains harboring the conjugative plasmid pAD1 excrete a small peptide, iAD1, which inhibits the sex pheromone cAD1. Studies making use of the host strain Streptococcus faecium 9790, which normally ...
Benzoylarginine peptidase and iminopeptidase profiles of Treponema denticola strains isolated from the human periodontal pocket
(Springer-Verlag; Springer-Verlag New York Inc., 1986-03)
Seven clinical isolates and the ATCC strain 35405 of Treponema denticola , obtained from human periodontal pockets, were studied for peptidase activity with several chromogenic compounds as substrates. The cell sonicates ...
int-h: an int mutation of phage [lambda] that enhances site-specific recombination
(Elsevier, 1980-07)
The mutation int-h3 maps in the int gene of coliphage [lambda] and results in the synthesis of an integrase with enhanced activity, which is manifested by an ability to support [lambda] site-specific recombination relatively ...
Sex pheromones and plasmid transfer in Enterococcus faecalis
(Elsevier, 1989-05)
Plasmid-free Enterococcus faecalis excrete peptides (sex pheromones) which specifically induce a mating response in strains harboring certain conjugative plasmids. The response is characterized by the synthesis of a "fuzzy" ...
Presence of Acinetobacter species among the predominant bacteria found in a contaminated metal-working fluid
(Elsevier, 1987-08)
The distribution of Acinetobacter species among the bacteria isolated from an unusually heavily contaminated petroleum-based water-soluble metal-working fluid used in a large North American automotive machining operation ...
Etiologic role of lactic dehydrogenase virus infection in an age-dependent neuroparalytic disease in C58 mice
(Elsevier, 1980-05)
Lactic dehydrogenase virus (LDV) associated with transplantable line Ib lymphocytic leukemia in C58/Wm mice, K36 lymphocytic leukemia in AKR/J mice, and the Gardner lymphosarcoma in C3H/HeJ mice elicited a fatal neuroparalytic ...
Analytical solutions to a generalized growth equation
(Elsevier, 1984-10-30)
Systems of the form occur in the analysis of biological networks. They also include as special cases the known growth laws and probability functions, famous differential equations like those of Bessel, Chebyshev, and ...
Growth equations: A general equation and a survey of special cases
(Elsevier, 1980-04)
Although growth in its various manifestations has been studied for centuries and although there are a large number of well-established growth "laws," that work is almost entirely empirical and lacks a theoretical foundation ...
