This study was conducted to determine the relationship between eosinophilia and parasitic infection in HIV-infected individuals. HIV-positive patients attending an HIV clinic in Birmingham were recruited and classified as either eosinophilic (>400 eosinophils/mm(3)) or non-eosinophilic. A demographic and parasitic risk history was taken and clinical examination was performed. Urine and stool we...

BACKGROUND Screening for syphilis with treponemal chemiluminescence immunoassays (CIA) identifies patients with discordant serology who are not identified with traditional screening methods (eg, CIA-positive, rapid plasma regain (RPR)-negative). We sought to describe the clinical characteristics and management of patients with discordant syphilis serology. METHODS From August 2007-October 200...

Comparative study on toxoplasma serology among HIV positive and HIV negative illicit drug users in Ahvaz, Iran

BACKGROUND & OBJECTIVES Mycoplasma pneumoniae is the most important and common cause of community-acquired pneumonia (CAP). The conventional detection methods (culture and serology) lack sensitivity. PCR offers a better approach for rapid detection but is prone to carry over contamination during manipulation of amplification products. Quantitative real-time PCR (qRT-PCR) method offers an attrac...

Antibodies are highly functional glycoproteins capable of providing immune protection through multiple mechanisms, including direct pathogen neutralization and the engagement of their Fc portions with surrounding effector immune cells that induce anti-pathogenic responses. Small modifications to multiple antibody biophysical features induced by vaccines can significantly alter functional immune...

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...

I F A SERUM contains a gamma globulin which will react with ( agglutinate, hemolyze or sens tize ) certain enetically well-defined red blood cells but not others, it is said to possess an antibody and the antibody is said to be specific for a certain property of the red cells. Thus the specificity of an antibody depends on this selective reactivity. This is often difficult to demonstrate if the...

Serology using a species-specific antigen for Mycobacterium leprae, PGL-I, could be a marker for the bacterial load of patients with leprosy. Various studies have identified the potential use of serology in the classification of patients for treatment purposes, case monitoring, identification of the risk of relapse and selection of household contacts with a higher risk of contracting the diseas...
