Several assays have been developed for detection of immunoglobulin G antibodies to Human herpesvirus 8 (HHV-8), including immunofluorescence assays (IFAs) and enzyme-linked immunosorbent assays (ELISAs). However, the specificity and sensitivity of these assays are not completely defined due to the lack of a "gold standard." Although IFAs based on primary effusion lymphoma (PEL) cell lines are u...
Controlling anaemia in pregnant women is carried out through iron folic acid tablets (IFA) supplementation. The IFA supplementation for Indonesia has been a long time, but the prevalence of among still high. results from evaluation management Locus Stunting 2021, showed that proportion anaemic higher who have taken IFA. Therefore, analysis was to identify risk factors had Data descriptively, al...
An indirect immunofluorescence assay (IFA) was evaluated as a confirmatory test for antibody to human immunodeficiency virus type 1 in U.S. blood donor sera previously found to be repeatedly reactive by enzyme immunoassay. IFA results were 100% concordant with a licensed Western blot (immunoblot) for 53 negative and 49 positive samples. Four samples which exhibited antibody to viral proteins fr...
The Bartels respiratory virus panel detection kit is an indirect fluorescent-antibody (IFA) method that uses pooled and individual antisera for tissue culture confirmation of seven respiratory viruses. We evaluated these reagents for detecting viral antigen in shell vial cultures and by direct staining of cells from respiratory specimens. The isolation from 254 specimens of respiratory viruses ...
Leptospirosis is a widespread zoonotic disease that affects all mammals, including humans, in different parts of the world. Clinical recognition of leptospirosis is challenging, and the definitive serologic diagnosis assay, the microscopic agglutination test (MAT), is time-consuming and difficult to conduct. In this study, an indirect immunoperoxidase (IIP) test to detect Leptospira-specific an...
The monoclonal antibody (anti-IFA) raised (Pruss et al., 1981, Cell 27:419-428) against an intermediate filament antigen, which is widespread throughout phylogeny, has been shown here to cross-react with higher plants. On immunoblotting, anti-IFA cross-reacted with proteins in homogenates of carrot suspension cells and of meristematic cells from onion root tips. A 50-kD cross-reactive protein w...
An indirect immunofluorescent antibody procedure (IFA) for the detection and typing of herpes simplex virus (HSV) and an enzyme-linked immunosorbent assay (ELISA) procedure were compared with conventional viral culture. Specimens for culture and ELISA were inoculated into serum free viral transport medium (VTM) and, for IFA, onto slides provided in the kit. Tissue cultures (MRC-5 and primary ra...
BACKGROUND The indirect immunofluorescence assay (IFA) is considered a reference test for scrub typhus. Recently, the Scrub Typhus Infection Criteria (STIC; a combination of culture, PCR assays and IFA IgM) were proposed as a reference standard for evaluating alternative diagnostic tests. Here, we use Bayesian latent class models (LCMs) to estimate the true accuracy of each diagnostic test, and...
An indirect fluorescence assay (IFA) with monoclonal antibodies developed for the detection of Cryptosporidium oocysts in fecal smears (Meridian Diagnostics, Inc., Cincinnati, Ohio) was compared with the Zeihl-Neelsen-modified acid-fast stain (MAFS) in 119 human fecal specimens collected between 1984 and 1987. The sensitivity of the IFA was 100%; all 56 specimens positive by MAFS exhibited fluo...
Iterated Finite Automaton (IFA) is invented by Wolfram for studying the conventional Finite State Automata(FSA) by means of A New Kind of Science (NKS) methodology. An IFA is a composition of a finite state automaton and a tape with limited cells. The complexity of behaviors generated by various FSA operating on different tapes can be visualized by two dimensional patterns. Through enumerating ...
