Med., 1979 , 128 (3). 241-249 The nucleoprotein (NP) antigen isolated from influenza A virus by solubilization with Triton X-100 (TX-100) and further electrophoresis with SDS-cellulose acetate membrane gave a single band on SDS-pol...

A clinical, parasitologic, and serologic study carried out between 1988 and 1996 on 59 acute-phase patients in areas of western Venezuela where Chagas' disease is endemic showed 19 symptomatic patterns or groups of symptoms appearing in combination with different frequencies. The symptomatic pattern with the highest frequency was that showing simultaneously fever, myalgia, headache, and Romaña'...

Ovine Johne's disease, or paratuberculosis, occurs in many countries. In Australia, surveillance using serology is used as part of a control program, but the testing regime is costly relative to its sensitivity. For this reason, culturing of Mycobacterium avium subsp. paratuberculosis in fecal samples pooled from a number of sheep was evaluated. Initially, the effect of pooling on the sensitivi...

ALI, A. S., M. M. LILA: Serologic relationship and antigenic dominance among five Aujeszky’s disease virus isolates. Vet. arhiv 75, 399-405, 2005. ABSTRACT The serologic relationship and antigenic dominance among five Aujeszky’s disease virus (ADV) isolates, designated VBA1, VBA2, VBA3, mA1p and CD, was studied using homologous and heterologous antigens and sera. Cross-serum neutralization test...

Serologic evaluation for Zika virus (ZIKV) infection currently includes an initial screen using an anti-ZIKV IgM antibody capture enzyme-linked immunosorbent assay (MAC-ELISA) followed by supplemental testing of specimens with nonnegative results by a plaque reduction neutralization test (PRNT). We compared the performance characteristics of three ELISAs for the detection of IgM class antibodie...

PURPOSE To investigate whether Helicobacter pylori infection is associated with normal tension glaucoma (NTG). METHODS One hundred consecutive NTG patients (group 1) from an outpatient glaucoma clinic were enrolled. Medical records of the 88 control participants (control 1) of the outpatient clinic, and 104 NTG patients (group 2) and 1116 healthy controls (control 2) (1220 subjects in total) ...

BACKGROUND Rheumatic symptoms were commonly described among soldiers who served in previous wars. OBJECTIVE To describe the frequency of rheumatology consultations, along with the diagnoses, and abnormal results on serologic testing in Gulf War veterans evaluated for Gulf War syndrome. METHODS The medical records of the first 250 consecutive Gulf War veterans referred to the comprehensive c...

To the Editor: We read with great interest the article by Xynos et al. reporting 2 cases of leishmaniasis in patients treated with biologic drugs (1). Although we agree with most of the article, we are not totally convinced that serologic analysis alone could be used to screen for leishmaniasis before initiation of biologic or immunosuppressive treatments. Evidence indicates that serologic anal...

BACKGROUND Clinical algorithms for the workup of celiac disease often recommend the use of serologic assays for initial screening, followed by duodenal biopsy for histologic confirmation. However, the majority of duodenal biopsies submitted to pathology for "rule out celiac" are negative. The objective of this study was to determine the underlying causes for this low diagnostic yield. METHODS...

A new method for the detection of pseudorabies antibody in swine sera was developed by use of the indirect immunoperoxidase plaque staining test. The indirect immunoperoxidase plaque staining test demonstrated serologic responses in pigs that were subcutaneously infected with pseudorabies virus. The test had a sensitivity and a specificity comparable to those of the complement-dependent neutral...
