To investigate the prevalence of spotted fever group rickettsioses in Korea, a serosurvey of Japanese spotted fever rickettsiosis in patients with acute febrile illness was conducted with an indirect immunofluorescence assay. Overall, 19.88% of the patients were found to have polyvalent antibody against Rickettsia japonica. This study is the first documentation of spotted fever group rickettsio...

Babesiosis is an emerging zoonosis now found in several areas of the world. Using PCR and indirect immunofluorescence assay, we have diagnosed the first case of human babesiosis caused by Babesia microti in Spain. Diagnosis was delayed because of the nonspecific clinical symptoms that occurred in an immunocompetent patient.

In four cases of pulmonary toxoplasmosis occurring in patients with acquired immunodeficiency syndrome, Toxoplasma sp. was discovered in bronchoalveolar-lavage fluid (three cases) and in lung biopsy specimen (one case) by using the following methods: direct examination of smears stained with eosine-methylene blue fast stain, indirect immunofluorescence assay, and inoculation of MRC5 fibroblast ...

We studied antibody response in 9 healthcare workers in Jeddah, Saudi Arabia, who survived Middle East respiratory syndrome, by using serial ELISA and indirect immunofluorescence assay testing. Among patients who had experienced severe pneumonia, antibody was detected for >18 months after infection. Antibody longevity was more variable in patients who had experienced milder disease.

We determined the optimal cutoff titers in admission and convalescent-phase samples for scrub typhus indirect immunofluorescence assay using Bayesian latent class models. Cutoff titers of ≥1:3,200 in an admission sample or of a ≥4-fold rise to ≥1:3,200 in a convalescent-phase sample provided the highest accuracy (sensitivity, 81.6%; specificity, 100%).

The AA describe the first italian case of Lyme Disease in a middle aged woman: the patient developed after a tick bite the classical erythema chronicum migrans lesions and one month later an oligoarthritis. By indirect immunofluorescence assay it has been found a significant titre compatible with an infection by Borrelia burgdorferi, the causative agent of Lyme Disease.

We describe the development and evaluation of an indirect immunofluorescence assay (IFA) kit for rapid and sensitive detection of coxsackievirus A2, -4, -5, -6, and -10. This IFA kit was determined to have 95.9 to 100% sensitivity and 95.8 to 97.2% specificity. It also proved to be beneficial in reducing the number of enteroviruses that are untypeable in the clinical virology laboratory.

Simian cytomegalovirus was substituted for human cytomegalovirus in an enzyme-linked immunoassay. Unlike the indirect immunofluorescence assay which demonstrates a two-way cross-reactivity, only one-way cross-reactivity was observed. Altering the method of simian antigen preparation gave some insight other this different reactivity.

Background: Immune thrombocytopenia is a hematologic disorder characterized by low platelet count and variable bleeding manifestations due to immune-mediated platelet destruction and/or suppression of platelet production. This study was performed to evaluate characteristics and clinical presentations of adult patients with immune thrombocytopenia and to explore the clinical value of platelet an...
