Traditional methods for detection and serotyping of enterovirus infections are virus isolation and immunofluorescence assay (VI-IFA), which are labor-intensive and time-consuming. Recently, VP1 gene has been targeted to develop a CODEHOP-based RT-PCR (VP1-CODEHOP) for the same purpose. In this study, we conducted a 5-year enterovirus surveillance comparing the VI-IFA and VP1-CODEHOP tests. Thro...
BACKGROUND T cell receptor (TCR) peptide vaccination is a novel approach to treating multiple sclerosis (MS). The low immunogenicity of previous vaccines has hindered the development of TCR peptide vaccination for MS. OBJECTIVE To compare the immunogenicity of intramuscular injections of TCR BV5S2, BV6S5 and BV13S1 CDR2 peptides in incomplete Freunds adjuvant (IFA) with intradermal injections...
Anti-nuclear antibody (ANA) testing is widely used as a screening test in Autoimmune diseases. The most commonly used method for ANA testing is ANAimmunofluorescence assay (ANA-IFA). This study compared the diagnostic performance of Enzyme linked immuno sorbent assay (ELISA) with IFA for the detection of ANA. 125 samples were tested which included 75 samples from patients with clinical suspicio...
This study evaluated an indirect immunofluorescence assay (IFA) to detect feline immunodeficiency virus infection (FIV) antibody in a comprehensive epidemiological survey of FIV in Argentina. IFA modified in our laboratory, was compared with two other immunoassays, western blot (WB) and a sandwich immunochromatographic commercial kit (SI), and also with a direct polymerase chain reaction (PCR) ...
The utility of the indirect immunofluorescent antibody (IFA) technique for diagnosis of herpes simplex virus (HSV) infection was examined by testing specimens for this agent from 31 patients with encephalitis or meningitis, 17 with conjunctivitis, 19 with genital disease, and 1 with genital disease and meningitis. Brain biopsy tissue from four patients with encephalitis was positive by IFA and ...
Infection with Borrelia burgdorferi is common in horses and ponies from the New England and mid-Atlantic regions of the United States. Here, we evaluated luciferase immunoprecipitation systems (LIPS) for profiling antibody responses against three different antigenic targets for the diagnosis of equine B. burgdorferi infection. LIPS testing of horse serum samples suspected of Lyme infection reve...
Violence involving firearms poses a serious threat to public safety in urban areas. The present study examines how illegal firearm availability (IFA) is related to firearm violence at the neighborhood level. We analyzed 3 years (from 2005 to 2007) of recovered firearm and violent index crime data from Newark, New Jersey. Violent index crime is separated into three categories by level of firearm...
In this study, we examined the diagnostic accuracy of the InBios Scrub Typhus Detect IgM enzyme-linked immunosorbent assay (ELISA) and determined the optimal diagnostic optical density (OD) cutoffs for screening and diagnostic applications based on prospectively collected, characterized samples from undifferentiated febrile illness patients in northern Thailand. Direct comparisons with the sero...
OBJECTIVE To describe the epidemiology of respiratory syncytial virus (RSV) and human metapneumovirus (hMPV) in Colombia from 2000 - 2011, including seasonal trends. METHODS Nasopharyngeal aspirates and/or throat swabs from 14 870 patients with acute respiratory infections (ARI) were studied. Two subgroups were analyzed using molecular biology techniques. The first consisted of 264 RSV indire...
هدف: تعیین کمترین عیار با ارزش آنتی بادی ضد توکسوپلاسماگوندی آی در تشخیص آلودگی گوسفند، در الایزای غیر مستقیم و IFA، با استفاده از آنتی ژن محلول SAG-1 دروسترن بلات، به عنوان یک پروتئین مشخص کننده عفونت. حیوانات: یکصدوده راس گوسفند بومی بالغ از 14 گله در اطراف ارومیه. روش: جدا نمودن سرم و تعیین آخر رقت مثبت هر سرم با آزمونهای IFA، والایزا انجام شد و آخرین رقت مثبت هر سرم با آنتی ژن محلول SAG-1...
