Iron acquisition by Haemophilus influenzae.
The mechanisms for acquisition of iron by Haemophilus influenzae and their role in pathogenesis are not known. Heme and nonheme sources of iron were evaluated for their effect on growth of type b and nontypable strains of H. influenzae in an iron-restricted, defined medium. All 13 strains acquired iron from heme, hemoglobin, hemoglobin-haptoglobin, and heme-hemopexin. Among nonheme sources of p...

متن کاملDegradation of certain nucleotides by Haemophilus influenzae and Haemophilus aegyptius.
Little attention has been paid to the degradation of nucleotides by the genus Haemophilus although Lwoff and Lwoff (1937a, b) and McIlwain and Hughes (1948) demonstrated that Haemophilus parainfluenzae was capable of destroying diphosphopyridine nucleotide (DPN). More recently, Kalckar (1954) reported the occurrence of a specific nucleotide pyrophosphatase and associated nucleotide phosphatase ...
متن کاملExtraction and Purification of Haemophilus influenzae Type b Lipooligosaccharide by Modified Phenol Method
Introduction : Haemophilus influenzae type b (Hib) is a Gram negative bacterium and one of the causative agents of acute bacterial meningitis, especially in infants and children less than 5 years old. Lipooligosaccharide (LOS), one of the virulence factors which plays an important role in pathogenesis of Hib, has multiple applications in diagnosis and conjugate vaccines. In this study, LOS ex...
متن کاملSeptic arthritis caused by noncapsulated Haemophilus influenzae.
Since the introduction of type b Haemophilus influenzae vaccination, noncapsulated H. influenzae has become responsible for most cases of invasive H. influenzae diseases. In our two cases of septic arthritis, we isolated strains with β-lactamase-positive amoxicillin-clavulanate resistance (BLPACR). Thus, the increasing prevalence of BLPACR should be taken into account when empirical therapy is ...
