Methylase activities from Haemophilus influenzae that protect Haemophilus parainfluenzae transforming deoxyribonucleic acid from inactivation by Haemophilus influenzae endonuclease R.
Specific methylases that have the properties of deoxyribonucleic acid (DNA) modification enzymes have been isolated from Haemophilus influenzae strain Rd. Two activities ((Methylase IIa and methylase III) were found to protect transforming DNA of H. parainfluenzae from the action of H. influenzae restriction enzymes. To determine the specificty of the protection, a procedure based on biological...
متن کاملGenetic integration in the heterospecific transformation of Haemophilus influenzae cells by Haemophilus parainfluenzae deoxyribonucleic acid.
The in vivo chemical linkage of Haemophilus parainfluenzae deoxyribonucleic acid (DNA) with the H. influenzae genome has been found to occur at a much higher level than is suggested by the low efficiency of the heterospecific transformation of an antibiotic resistance marker. This linkage, about 60% of the level with homospecific DNA, was found to involve alkali-stable bonding. The amount of ho...
متن کاملClustering of an outer membrane adhesin of Haemophilus parainfluenzae.
Haemophilus parainfluenzae synthesizes an outer membrane protein adhesin which mediates binding to oral streptococci, salivary pellicle, and neuraminidase-treated erythrocytes. An indirect gold labeling technique and immunoelectron microscopy verified the location of this outer membrane protein. Further, a clustering of gold particles was observed in irregular patches at the cell surface.
متن کاملLiver abscess caused by Haemophilus parainfluenzae.
A case of liver abscess caused by Haemophilus parainfluenzae in an otherwise healthy adult is described which responded to medical management without surgery. This we believe to be the first reported case of liver abscess caused by this organism in the English medical literature.
متن کاملAntimicrobial susceptibility of Haemophilus parainfluenzae.
Fifty random clinical isolates of Haemophilus parainfluenzae were tested for their susceptibility to 10 antibiotics by a microtiter broth dilution method. Three of the strains tested were resistant to ampicillin, whereas eight were resistant to tetracycline. All strains tested were susceptible to chloramphenicol, kanamycin, gentamicin, cephalothin, and colistin. The ranges of minimal inhibitory...
