The incidence of infectious syphilis in men who have sex with men and human immunodeficiency virus-infected patients has increased steadily in Victoria, Australia, since 2002. A TaqMan real-time PCR assay targeting the polA gene of Treponema pallidum (TpPCR) was developed. The analytical sensitivity of the assay was estimated to be 1.75 target copies per reaction. Initially, the assay was used ...
background and objective: opportunistic infections are the leading cause of death among patients subjected to the human immunodeficiency virus (hiv) infection and acquired immune deficiency syndrome (aids). the aim of this study was to compare the seroprevalence of cytomegalovirus (cmv) and toxoplasmosis infection in newly diagnosed hiv infected patients with healthy controls and it’s correlat...
BACKGROUND Autoimmune serologies are often obtained in the initial evaluation of uncharacterized interstitial lung disease (ILD). Whether this practice is helpful in delineating connective-tissue disease related ILD (CTD-ILD) is not well known. We assessed the frequency of incident CTD-ILD as detected by autoimmune serology testing and presenting clinical signs and symptoms. METHODS Consecuti...
background : the ifa test is one of the most usual methods for detecting anti- toxoplasma antibodies, although it has not any unique standardization. it seems that the microscopic judgment of results is an important confounder in ifa test. therefore, we conducted the present study to clarify the role of microscopic observer, and other confounders on the test. methods: eighty sera were collect...
A qPCR array was designed to facilitate forensic serological identification of unknown stains and fluids. In our approach, the flow-through of a DNA purification column is further purified for total RNA. Therefore, the DNA preparation is fully available for forensic DNA analysis whereas the RNA fraction is processed for serological examination by mRNA analysis. The RNA fraction is first subject...
Although automation was introduced into biochemistry in 1957 (Skeggs, 1957), it was not until 1963 that McNeil, Helrick, and Ferrari (1963) first described a mechanized technique forABO grouping. This was followed a few months later by a method employing the AutoAnalyzer continuous flow principle by which up to 40 samples per hour could be both ABO and Rh (D) grouped (Sturgeon, Cedergren, and M...
chemical foundation of these disciplines. The author avoids the principal pedagogic sin of talking, in an equal tone of voice, of subjects of widely varying importance. This is clearly one man's account, but it is balanced, reasonable, and so lucid that one can read it with pleasure. It is a pity that the production of the book is not of as high a standard as its contents. In the review copy a ...
Schmidt, Jean M. (State University of Iowa, Iowa City) and Robert L. Richardson. Serology of Bacterionema matruchotii. J. Bacteriol. 83:584-589. 1962.-Serological relationships of Bacterionema matruchotii were studied by means of the complement-fixation reaction. A common complement-fixing antigen was demonstrated in 37 strains of this organism. Serological relationships to species in the gener...
Both molecular and serological assays have been used previously to determine the etiology of community-acquired pneumonia (CAP). However, the extent to which these methods are correlated and the added diagnostic value of serology for respiratory viruses other than influenza virus have not been fully evaluated. Using data from patients enrolled in the Centers for Disease Control and Prevention (...
Syphilis serology is a basic screening test for the workers who want to go abroad. Many countries reject migrant workers who have reactive syphilis serology. Biological false reactives warrant repeated syphilis serology. We prospectively studied 30 patients (25 males and 5 females) who had biological false reactive VDRL tests (VDRL reactive, confirmatory TPHA negative). Affirmative tests for sy...
