Liquid medium for growth of Legionella pneumophila.
The medium described is a simple yeast extract broth capable of growing large number of Legionella neumophila, the causative organism of Legionnaires disease. Filtration was chosen as a means of sterilization, since medium that was autoclaved did not support growth without the presence of Norite A. The filtered medium gave rapid cell growth and maintained the initial antigen production. The obs...
متن کاملChemically defined medium for Legionella pneumophila growth.
A chemically defined medium containing 18 amino acids, inorganic salts, rhamnose, choline, and ferric pyrophosphate has been developed. The final concentrations of salts and amino acids were modeled after yeast extract. This medium supported the growth of four serogroups of Legionella pneumophila. Growth in shake cultures at 37 degrees C produced a lag time of approximately 5 h and a generation...
متن کاملCharcoal-yeast extract agar: primary isolation medium for Legionella pneumophila.
Charcoal-yeast extract agar is a new bacteriological medium that supports excellent growth of the Legionella pneumophila. It results from modifications made in an existing L. pneumophila medium, F-G agar. Yeast extract, instead of an acid hydrolysate of casein, serves as the protein source. Beef extractives and starch are not added. Activated charcoal (Norit A or Norit SG) is included at 0.20% ...
متن کاملInvestigation of Legionella Pneumophila bacteria in hospital water supply systems
Introduction: Legionella Pneumophila bacteria is known as one of the most important nosocomial infections and the most common cause of death in patients. This study was aimed to identify Legionella Pneumophila bacteria in hospital water supply systems. Material and Methods: This descriptive cross-sectional study was performed to identify Legionella pneumophila in hot and cold-water systems of i...
متن کاملUltrastructure of Legionella pneumophila.
Eleven lung samples positive for Legionnaires' disease, 12 strains of Legionella pneumophila cultured on various bacteriological media, and one strain growth in the yolk sac of fertile hens' eggs were examined by negative staining, thin sectioning, and scanning electron microscopy. All organisms studied were ultrastructurally similar irrespective of strain, source, or method of cultivation, pre...
