Growth and bacteriolytic activity of a soil amoeba, Hartmannella glebae.
A soil amoeba, Hartmannella glebae, could grow on a variety of gram-positive and gram-negative bacteria, although the rate of growth was faster in the presence of gram-negative bacteria. The amoeba, however, could not use yeasts, molds, or a green alga as a nutritional source. The extract prepared from amoebae grown in the presence of Aerobacter aerogenes and Alcaligenes faecalis could lyse int...
متن کاملPurification and specificity of bacteriolytic enzyme I from Hartmannella glebae.
A soil amoeba (Hartmannella glebae), when grown in conjunction with Enterobacter aerogenes and Alcaligenes faecalis, produced two enzymes. Enzyme I was purified by gel filtration on Sephadex G-100 and chromatography on diethylaminoethyl-cellulose. It is a basic protein. The analysis of the enzymic digest of the cell walls of Micrococcus lysodeikticus after reduction and acid hydrolysis showed t...
متن کاملBacteriolytic activity in staphylococci.
The bacteriolytic activity of Staphylococcus aureus and Staphylococcus albus strains was tested with various media. Whereas S. aureus strains were found to be active under all conditions, the percentage of active S. albus strains was significantly influenced by the composition of the medium. Ionic strength and concentration of the organic nitrogen source were found to be the main factors affect...

Identification of "Ryan Virus" as an amoeba of the genus Hartmannella.
A recent paper (Pereira, et al., 1966) reported the isolation in Britain of several strains of an antibiotic-resistant infective agent that caused unusual cytopathic effects when inoculated into cell cultures. The new agent was evidently recoverable from the respiratory tract in certain patients, mostly young children, with illnesses of varying severity but with fever and respiratory symptoms a...
