Anti-gamma haemolysin as a diagnostic test in staphylococcal osteomyelitis.
The anti-alpha-haemolysin test is widely used in the diagnosis of staphylococcal osteomyelitis. An additional test would be welcomed because raised antibodies to this antigen are not seen in all proven cases. This communication reports that anti-gamma-lysin was present in the serum of most of the 19 patients with proven staphylococcal osteomyelitis studied here. In two cases followed up after c...
متن کاملApplication of Riboflavin-Deficient Rat Erythrocytes in the in Vitro Assay of Faba Bean Toxicity
Background: Faba bean toxicity (favism) is a common condition observed in our region. Objective: To develop a short and simple technique involving the use of riboflavin-deficient rats to test in vivo faba bean toxicity. Methods/Results: Sprague Dawley rats were maintained on a riboflavin-deficient diet and their vitamin B2 status was monitored by the assay of erythrocyte glutathione reductase (...
متن کاملThe clinical evaluation of staphylococcal anti-alpha haemolysin titres in patients' sera.
a haemolysin and the pathogenicity of Staphylococcus aureus has long been a matter for discussion. Christie, North, and Parkin (1946) stated that the production of a haemolysin is essential for full pathogenicity, and that coagulase-positive strains which produced no a haemolysin might be regarded as non-pathogenic. Marks (1952) found a close correlation between pathogenicity and the production...
متن کاملThe staphylococcal toxins γ-haemolysin AB and CB differentially target phagocytes by employing specific chemokine receptors.
Evasion of the host phagocyte response by Staphylococcus aureus is crucial to successful infection with the pathogen. γ-haemolysin AB and CB (HlgAB, HlgCB) are bicomponent pore-forming toxins present in almost all human S. aureus isolates. Cellular tropism and contribution of the toxins to S. aureus pathophysiology are poorly understood. Here we identify the chemokine receptors CXCR1, CXCR2 and...
متن کاملEco-genotoxicology: Micronucleus Assay in Fish Erythrocytes as In situ Aquatic Pollution Biomarker: a Review
The application of fish erythrocyte micronucleus assay in pollution monitoringparticularly in water has been described as sensitive biodetector of genotoxicants. The pervasiveness of this technique has been characterized by varieties of sensitivities and adequacies in forms of early warning of ecodamage and toxicity, stresses on the health of organisms and ecosystems. Since biodiversity-rich fr...
