BACKGROUND The purpose of this study was to evaluate the immunoglobulin (Ig) G avidity of serological toxoplasmosis testing in patients with ocular inflammation and to determine the clinical manifestations of ocular toxoplasmosis. METHODS A retrospective review of all patients presenting with ocular inflammation to the Hospital Universiti Sains Malaysia, Kelantan, Malaysia between 2005 and 20...

results in this setting, detection rate of the disease is 34.86%, if the high normal titer for the wrights test titer assumed 1/80 and is 44.95% if the titer assumed 1/40, while elisa test had detection rate of 58.72% for those suspicious cases. furthermore, the detection rate for diagnosis of active brucellosis with 2me tests was 17.54% with high normal titer of 1/80 and was 59.64% with a high...

The virological surveillance of 3582 wild waterfowl in northern Australia from 2004 to 2009 for avian influenza virus (AIV) found an apparent prevalence (AP) of 1% (31 of 2989 cloacal swabs; 95% CI: 0.71%-1.47%) using a Taqman Type A real-time reverse transcription polymerase chain reaction test and no viral isolations from 593 swabs tested by the embryonating chicken egg culture method. From s...

Lyme disease is emerging in eastern and central Canada, and most cases are diagnosed using the two-tier serological test (Enzyme Immuno Assay [EIA] followed by Western blot [WB]). Simplification of this algorithm would be advantageous unless it impacts test performance. In this study, accuracy of individual proteins of the IgG WB algorithm in predicting the overall test result in samples from C...

To investigate the changes in personal attitudes and behaviour before after negative serological test results for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies. Cross-sectional questionnaire survey. A survey was conducted with 200 industry workers (68% males 32% females) who had previously tested SARS-CoV-2 The examined participants' self-reported general towards disea...

The Italian workers D'Alessandro, Oddo, Comes, and Dardanoni (1949) and D'Alessandro and Dardanoni (1953) described the isolation of four serologically active components of Reiter's treponeme. These contributions represent milestones in the sero-diagnosis of syphilis since they were the initial systematic investigations into the serological components of treponemes. One of the components was co...

Tularaemia is an emerging anthropozoonosis transmitted by contact with infected animals and through arthropod bites, inhalation, or ingestion. We describe a pulmonary nodule suggesting cancer in a 70-year-old man. Histological analysis excluded neoplasia, and bacteriological culture excluded tuberculosis. Serological testing and PCR Francisella were positive for this hunter patient, then treate...

Retrospective analysis of IgG test results and patterns for measles, mumps, and rubella revealed generally high seropositivity rates, with that of mumps being the lowest. A simplified cost analysis shows that when there is a suspicion of nonimmunity, serological testing may be cheaper than vaccination.

OBJECTIVES To analyze postvaccination serological status in pregnant women inadvertently vaccinated against rubella in the state of Rio de Janeiro, Brazil. METHODS This was a cross-sectional study of pregnant women 15 to 29 years old, vaccinated against rubella and measles from November 2001 to March 2002, who were unaware of their pregnancy at the time of vaccination or who became pregnant w...

BACKGROUND/OBJECTIVES Herpes simplex virus type 2 (HSV-2) is a common infection among HIV infected people. HSV type specific serologies permit the diagnosis of previously unrecognised HSV-2 infection. While substantial psychosocial morbidity has been associated with a clinical diagnosis of genital herpes, the burden associated with a serological diagnosis of HSV-2 is unclear. This study prospec...
