The anticomplement immunofluorescence (ACIF) test was compared with complement fixation and fluorescent antibody to membrane antigen procedures for the detection of antibody to varicella-zoster virus. All of 50 sera from pregnant women contained antibody measured by ACIF (titer, greater than or equal to 1:10); only 27 (54%) were positive by complement fixation (P less than 0.01). For 16 paired ...
A direct rapid immunohistochemical test (dRIT) was evaluated under field and laboratory conditions to detect rabies virus antigen in frozen and glycerol-preserved field brain samples from northwestern Tanzania. Compared to the direct fluorescent antibody test, the traditional standard in rabies diagnosis, the dRIT was 100% sensitive and specific.
Rapid and accurate immunological confirmation of presumptively positive gonococci could be facilitated with the Phadebact Gonococcus Test, a slide coagglutination procedure. The test was compared with carbohydrate utilization and fluorescent-antibody tests on 235 clinical isolates. With the coagglutination procedure, 97.1% of the isolates were identified as compared with 93.1% by carbohydrate u...
the biological control ability of fluorescent pseudomonas spp. results from competition for space and untrient, antibiosis and colonization in the rhizosphere. biocontrol fluorescent pseudomonads produce a wide variety of antibiotics. in this study, the biocontrol ability of 39 strains of biocontrol pseudomonas fluorescens, was examined against fusarium graminearum the causal agent of wheat fus...
We evaluated a rapid, simple-to-perform assay for detecting antibodies to varicella-zoster virus by latex agglutination (LA); dilutions of test sera were added to latex particles coated with varicella-zoster virus antigen. We tested 878 serum specimens by LA and with fluorescent antibody to membrane antigen; of these, 227 were also tested by a commercially marketed enzyme-linked immunosorbent a...
BACKGROUND The need for economical rabies post-exposure prophylaxis (PEP) is increasing in developing countries. Implementation of the two currently approved economical intradermal (ID) vaccine regimens is restricted due to confusion over different vaccines, regimens and dosages, lack of confidence in intradermal technique, and pharmaceutical regulations. We therefore compared a simplified 4-si...
The rapid fluorescent-antibody staining technique described by Kellogg and Deacon for staining Neisseria gonorrhoeae and Treponema pallidum was applied to fluorescent-antibody tests for group A streptococci and enteropathogenic Escherichia coli. Results obtained with this staining technique were compared with results using the conventional staining procedure; excellent correlation was obtained....
