BACKGROUND Known predictors of neurosyphilis were mainly drawn from human immunodeficiency virus (HIV)-infected syphilis patients, which may not be applicable to HIV-negative populations as they have different characteristics, particularly those with neurological symptoms. This study aimed to identify novel predictors of HIV-negative symptomatic neurosyphilis (S-NS). METHODS From June 2005 to...

Serological test based on IHA (Indirect Haemagglutination Method) was performed in 100 cases of hepatic abscess. The test was 100% sensitive and 94% specific. The cut off point of antibody titer between normal population and patients with invasive amoebiasis was 1:128. Antibody titer in amoebic liver abscess was 1:5242 +/- 2795. A significant (P less than 0.001) correlation was found between to...

BACKGROUND Hepatitis B virus (HBV) infection is the most common cause of liver disease in endemic areas such as South Korea. After HBV vaccination, hepatitis B surface antibody (HBsAb) titers gradually decrease. Trends in HBsAb titers have not been evaluated among children in South Korea over the past decade. METHODS We screened 6155 patients (aged 7 months to 17 years) who underwent HBV anti...

OBJECTIVE Acute respiratory worsening is defined as the unexpected rapid deterioration of idiopathic pulmonary fibrosis (IPF), and idiopathic acute respiratory worsening is known as an acute exacerbation of IPF. Torque teno virus (TTV) is a circular single-stranded DNA virus whose pathological significance remains unclear. The aim of the present study was to investigate the prevalence and titer...

BACKGROUND Repeated nontreponemal serologic test for syphilis titers is recommended to evaluate treatment response. However, it is unknown whether serum rapid plasma reagin (RPR) titer can serve as a surrogate for determining the efficacy of treatment in general paresis (GP) remains unknown. METHODS We retrospectively reviewed data from 105 GP patients, who were divided into two groups (62 CS...

The infectious bronchitis (IB) is divesting diseases of poultry. Hence, this study determined the maternally derived antibody (MDA) titer IBV and comparison two IB vaccine in layer. A total 1600 birds were equally allocated into groups (group-A group-B). group-A group-B vaccinated by different vaccines having strain “B1-Strain ND+Massachusetts B-41 Strains IBV” “Hitchner-B1 Strain H120 respecti...

A new latex agglutination test for rubella virus was used to test sera with a hemagglutination inhibition titer of less than or equal to 8 (97 specimens) or greater than or equal to 256 (158 specimens). Maximum latex agglutination test sensitivity was achieved when low-titer sera were tested undiluted and high-titer sera were diluted (1:10). A modification of the protocol of the manufacturer re...

OBJECTIVE The purpose of this study was to assess the effect of several maternal variables on the serologic response following the treatment of syphilis in pregnancy. METHODS A 5-year chart review identified 95 patients coded with syphilis at Hermann Hospital. Inclusion criteria were 1) serologically confirmed syphilis infection during the index pregnancy, 2) complete treatment during the ind...

1. Antibodies can be extracted from the brain and spinal cord of rabbits actively or passively immunized with typhoid bacilli. 2. The titers of the antibodies in the extracts of brain and cord depend upon the titer of the blood serum. In actively immunized rabbits the following numerical relationships exist between the titers of the serum and of these organ extracts: The ratio of the titer of t...

BACKGROUND AND OBJECTIVES We recently demonstrated that direct antiglobulin titer (DAT) positive, blood group A or B newborns born to group O mothers had a high incidence of hyperbilirubinemia, attributable to increased hemolysis. We reanalyzed our data asking whether increasing DAT strength plays a modulating role in the pathophysiology of the hemolysis and hyperbilirubinemia. METHODS Data f...
