Sera from six outbreaks of legionellosis and four outbreaks of pneumonia of other etiologies were tested with the indirect immunofluorescence assay (IFA) as currently performed. The current IFA is at least as sensitive as the original test in detecting cases of Legionnaires disease (78 to 91%). By using Center for Disease Control criteria for a positive (fourfold increase in titer during conval...
A commercially available (cELISA) kit for diagnosing Anaplasma marginale infection in cattle was validated for diagnosing A ovis infection in sheep using the bovine serum controls as supplied by the manufacturer (BcELISA) and sheep serum controls from pathogen-free sheep (OcELISA). True positives were identified using two previously established assays, a nested PCR (nPCR) test and an indirect i...
Intraperitoneal free air (IFA) is sometimes accompanied by pneumatosis cystoides intestinalis (PCI); therefore, proper diagnosis is essential for PCI management. We report two cases of PCI with IFA. A 70-year-old female taking anti-psychotic medication for schizophrenia presented with repeated vomiting and high-grade fever. Computed tomography revealed small, linear gaseous cysts in the intesti...
In experimental tumor immunotherapy, incomplete Freund's adjuvant (IFA) has been considered as the "gold standard" for T-cell vaccination in mice and humans in spite of its considerable adverse effects. Recently, we succeeded in eliciting strong CTL responses in mice after vaccination with biodegradable poly(D,L-lactide-co-glycolide) (PLGA) microspheres (MS). In our study, we compared the immun...
چکیده مقدمه: ژیاردیا لامبلیا یکی از شایع ترین تک یاخته های روده ای انسان در سراسر جهان می باشد. تشخیص آن عمدتاً از طریق مشاهده مستقیم صورت می گیرد ولی روشهای مبتنی بر elisa، ifa، بعنوان تکنیکهای برتر، کاربردهای تحقیقاتی و اپیدمیولوژیکی دارد. برای طراحی تستهای قدرتمند با قدرت تشخیصی بالا نظیر دیپ استیک و یا کیت های تشخیصی سریع، اولین قدم تولید آنتی بادی پلی کلونال می باشد. لذا بر آن شدیم تا آنتی ...
Results, and Innovations in Nutrition Globally (SPRING) project that use secondary analysis of Demographic and Health Survey data to determine barriers to distribution and consumption of iron–folic acid (IFA) through antenatal care systems in a range of countries. This brief describes key characteristics of and barriers to successful IFA supplementation in Senegal. SPRING NUTRITION TECHNICAL BRIEF
We determined and compared the method detection limits (MDLalpha) of a PCR and an immunofluorescence assay (IFA) for detection of Cryptosporidium parvum oocysts in soils. Based on the MDLalpha and the quantitative nature and stability of the IFA, PCR analysis is not a useful screening step for soil studies of oocyst transport.
Functional neuroimaging studies suggest that neural networks that subserve reading are organized differently in dyslexic readers (DRs) and typical readers (TRs), yet the hierarchical structure of these networks has not been well studied. We used Granger causality to examine the effective connectivity of the preparatory network that occurs prior to viewing a non-word stimulus that requires phono...
The relationship between viral infection with Kaposi sarcoma-associated herpesvirus (KSHV) and the onset of Kaposi sarcoma (KS) in AIDS patients is incompletely understood. This study investigates the use of three serological assays to predict the development of KS in HIV-positive patients. Serially collected serum samples from 36 patients with KS and matched controls in the Swiss HIV Cohort St...
This study compared the three most commonly used assays for detecting Cryptosporidium sp. infections in cell culture: immunofluorescent antibody and microscopy assay (IFA), PCR targeting Cryptosporidium sp.-specific DNA, and reverse transcriptase PCR (RT-PCR) targeting Cryptosporidium sp.-specific mRNA. Monolayers of HCT-8 cells, grown in 8-well chamber slides or 96-well plates, were inoculated...
