A total of 349 human serum samples were examined for anti-Toxoplasma antibodies by the Murex Single Use Diagnostic System (SUDS) qualitative screening test, indirect hemagglutination assay (IHA), and indirect immunofluorescence assay (IFA). Concordant results with SUDS and IHA were obtained for 91.9% of serum samples; 8.9% were SUDS+ and IHA-; none were SUDS- and IHA+. Comparison of the SUDS as...

To evaluate the pathogenic role of thromoboxane (Tx) in endotoxic shock, the potential protective effects of the Tx synthetase inhibitor, 7-(l-imidazolyl)-heptanoic acid (7-IHA) was assessed and compared to that of imidazole in the rat. 7-IHA (30 mg/kg) administered iv 30 minutes prior to Salmonella enteritidis endotoxin (20 mg/kg, iv) improved the survival rate from 42% (n = 24) at 5 hours in ...

A Bayesian inference model was introduced to estimate community prevalence of Schistosomiasis japonica infection based on the data of a large-scale survey of Schistosomiasis japonica in the lake region in Hubei Province. A multistage cluster random sampling approach was applied to the endemic villages in the lake regions of Hubei Province in 2011. IHA test and Kato-Katz test were applied for th...

AIM To validate the use of a new mouse monoclonal antibody (1D5) directed against the N-terminal domain (A/B region) of the oestrogen receptor in an immunohistochemical assay (ER-IHA) for paraffin wax embedded tissue. METHODS Breast cancer specimens were surgically obtained from 119 previously untreated patients. For comparison, oestrogen receptor was measured from cytosol fractions using an ...

Envelope, capsid, and soluble antigens of Herpesvirus hominis (HVH) types 1 and 2 were compared to crude antigens (disrupted HVH-infected cells) for potency, type-specificity, and diagnostic value in the indirect hemagglutination (IHA) test. The envelope appeared to be the predominant component reacting in the IHA test, but recurrent HVH infections increased the reactivity of human sera with ca...

The aim of this study was to compare the use of indirect haemagglutination (IHA) and gel diffusion (GD) tests for serotyping Haemophilus parasuis by the Kielstein-Rapp-Gabrielson (KRG) scheme. All 15 serovar reference strains, 72 Australian field isolates, nine Chinese field isolates, and seven isolates from seven experimentally infected pigs were evaluated with both tests. With the IHA test, 1...

To evaluate the usefulness of the indirect hemagglutination (IHA) test in the epidemiological investigation of shigellosis, single serum specimens were tested from 50 patients with Shigella dysenteriae 1 (Shiga bacillus) infections, 103 asymptomatic contacts of these cases, 267 adult and 100 student control, and serum specimens collected during two outbreaks caused by S. sonnei and one outbreak...

Primary aldosteronism (PA) has been associated with cardiovascular hypertrophy and fibrosis, in part independent of the blood pressure level, but deleterious effects on the kidneys are less clear. Likewise, it remains unknown if the kidney can be diversely involved in PA caused by aldosterone-producing adenoma (APA) and idiopathic hyperaldosteronism (IHA). Hence, in the Primary Aldosteronism Pr...

Invasive zymodemes of the enteric protozoan Entamoeba histolytica infect the large intestine and cause extra-intestinal lesions such as amebic liver abscess (ALA). The clinical manifestations of ALA are protean, particularly in patients presenting in a non-endemic, desert country such as Kuwait, and diagnosis becomes problematic. In this study, we present cases of ALA to illustrate the clinical...
