Streptococcal L forms. II. Chemical composition.
Suspension of a streptococcal L form in hypotonic solutions is accompanied by loss of viability and structural disintegration (Panos and Barkulis, 1959). Consequently, a variable amount of water soluble material is lost in employing hypotonic solutions for washing procedures and results in only a residue portion remaining. Analyses of such residues in terms of the chemical constituents of the i...
متن کاملStreptococcal L Forms and Phage 1
This study showed that streptococcal L forms could not be isolated from children who were either carriers of group A streptococci or had disease due to this pathogen. It was possible to induce L colony formation in 15 strains of group A. Streptococcal bacteriophages were demonstrated in 20% of group A streptococci isolated from school children who were carriers, but did not have clinical eviden...
متن کاملSerological reactions of glycolipids from streptococcal L-forms.
Parent bacteria and L-forms of some streptococci of group A, group D, and Streptococcus MG share common antigens as shown by cross-reactivity in growth inhibition, complement fixation, and Ouchterlony tests. Cross-reactivity between these streptococci or their L-forms with a staphylococcal L-form, or Mycoplasma pneumoniae, was found only rarely and only in low-titer complement fixation tests. R...
متن کاملGroup A streptococcal L forms. I. Persistence among inoculated mice.
L forms induced from two strains of group A Streptococcus were inoculated intraperitoneally and intravenously into conventional and germ-free mice. After intravenous injection, streptococcal L forms disappeared very quickly from the blood, whereas, after intraperitoneal injection, it was possible to isolate them as long as 25 days after inoculation. Observations suggest that a certain degree of...
متن کاملEstimating the Relative Efficiency of Various Forms of Prevention At Different Stages of a Drug Epidemic
Drug use and problems change dramatically over time in ways that are often described as reflecting an “epidemic cycle”. We use simulation of a model of drug epidemics to investigate how the relative effectiveness of different types of prevention varies over the course of such an epidemic. Specifically we use the so-called LHY model (see Behrens et al., 2000b) which includes both “contagious” sp...
