indirect hemagglutination test for chlamydial antibodies.an indirect hemagglutination (iha) test is described for chlamydial antibodies in psittacosis diagnostic sera; for this test tanned sheep erythrocytes sensitized with a deoxycholate extract of chlamydia psittaci grown in vero cell monolayers were used. adaptation of the iha test to the microtiter system decreased sensitivity; nevertheless, the microtiter-iha test was more sensitive than the complement fixation test. lymphogranuloma venereum antibodies also were detected by using antigen extracte ...19724626906
detection of chlamydia psittaci by immunofluorescence.a direct fluorescent-antibody (fa) test was developed to detect chlamydia psittaci in dural impressions from specimen-inoculated mice. technical procedures for the test were compared. c. psittaci was found in mice after infection as early by the fa technique as it was by cytochemical staining methods usually used. the lymphogranuloma venereum organism was also stained by conjugated antibody to c. psittaci. a distinctive advantage of the described fa test is that organisms are identified immunolo ...19724626909

some consequences of the multiple infection of cell cultures by tric organisms.in bhk 21 cells infected with more than one tric organism the inclusions coalesce so that 30 hr. after infection only one inclusion per cell remains. six hours after infection the cells are as susceptible to further infection as uninfected cells.19724501841
the development of tric organisms in cell cultures during multiple infection.the relationship between multiplicity of infection and the yield of organisms and of polysaccharide was studied in bhk 21 cells infected with tric organisms. although an increase in the multiplicity of infection resulted in an increase in the absolute number of organisms per culture, there was a decrease in relation to the number of infecting organisms. the amount of polysaccharide produced was independent of multiplicity of infection; it was not limited by the concentration of glucose in the me ...19724501842
