CONTEXT Although the first commercial polyurethane condom was approved for use several years ago, no U.S. clinical trial has compared its performance to that of the latex condom. METHODS In a masked crossover study, 360 couples were randomized to use three polyurethane condoms and three latex condoms. After each use, couples recorded condom breaks, condom slips and other aspects of performanc...

The purpose of this experiment was to study the possible anthelmintic activity of papaya latex (Carica papaya) against Heligmosomoides polygyrus in experimentally infected mice. Five groups of BALB/C mice were infected with 100 Heligmosomoides polygyrus infective larvae/mouse. After patency (day 22) four groups of mice (groups B, C, D and E) were given papaya latex suspended in water at dose le...

This solid-phase immunoassay for detection of rheumatoid factor involves a specially prepared indium surface that renders protein layers visible and therefore does not require tagged protein. Using appropriate discriminatory values, we found agreement with results of a standard latex-fixation test in controls and patients with rheumatoid arthritis. About half of the patients with rheumatoid art...

In both the complement fixation test (CFT) and the serum agglutination test (SAT) titres were reproducible for the most part within a twofold range. They seldom exceeded these limits and never a fourfold range. Brucella abortus was successfully isolated in 86% of serologically positive cases and evidence is presented to confirm the use of the 30 International Units/ml level in the CFT as being ...

The aim of this study was the application of fluorescence polarisation assay (FPA) for the examination of bovine sera and comparison of the results of the assay with the results of Rose Bengal test (RBT), serum agglutination test (SAT), complement fixation test (CFT), and ELISA. Six hundred thirty-five sera from cattle, including 300 sera from healthy animals, 32 sera from animals regarded as s...

IgM rheumatoid factor was assayed by three routine methods: latex fixation; haemagglutination; and end point laser nephelometry in 69 patients with definite or classical rheumatoid arthritis and 58 patients with other non-rheumatoid arthropathies, selected prospectively according to the American Rheumatism Association clinical criteria. The operators of the assays were unaware of the clinical d...

Aim: To study the seroprevalence of leptospirosis in dogs in Kerala and to identify the most prevalent serovar. Materials and Methods: A total of 205 sera collected from dogs were screened for the presence of antibodies against leptospirosis by Microscopic Agglutination Test (MAT). Results: A seroprevalence rate of 71.12 per cent was observed. Leptospira interrogans serovar Autumnalis was found...

Sera collected from 63 sheep older than one year of age in two regions of Yalova were tested for anti- Toxoplasma gondii antibodies using the Sabin-Feldman Dye Test (SFDT) and Latex Agglutination Test (LAT). Of the 63 samples tested, 42 (66.66%) and 41 (65.08 %) were determined to be seropositive by SFDT and by LAT, respectively. Of the positive sheep serum samples, 23 were positive at a diluti...

The study was conducted to determine the prevalence and risk factors of toxoplasmosis in goats in Southern and central Ethiopia between October 2005 and May 2006. A total of 641 goats sera were tested using Modified Direct Agglutination Test (MAT), of which 480 (74.8% CI: 71.3, 78.2) were found to be positive. The highest prevalence was recorded in South Omo zone (82%) while the lowest was obse...
