The double diffusion precipitin test in human fascioliasis.

A Useful Application of the Agar Double-Diffusion Technique in the Precipitin Test

Descriptive study of Fascioliasis in Mazandaran province from seasonal

Introduction: About 2.400.000 human cases in 61 countries and 180000000 people at Fascioliasis infection risk, show the importance of human aspects of Fascioliasis around the world. In the north of our country (Iran) huge outbreaks of Fascioliasis have been seen and up to 10000 people have been infected with Fascioliasis in one of these outbreaks. So this study tries to show better criteria a...

Serum precipitin reactions in Hashimoto's thyroiditis.

Sera from certain patients with Hashimoto's disease or a related condition contain a non-precipitating antithyroglobulin which produces in double-diffusion tests with thyroglobulin a line of clearing in the agar. Two such sera are described. Other sera from examples of the disease give negative precipitin tests with thyroglobulin but combine with sera containing ;clear line', non-precipitating ...

New Approaches for the Laboratory Recognition of M Types of Group a Streptococci

The successful classification of Group A streptococci by the capillary precipitin technique requires a complete series of M type antisera which are sufficiently potent and specific to give unequivocal type-specific reactions with all the serotypes. Specific antisera for this purpose have been prepared by absorption with heterologous streptococci. Unabsorbed antisera have been employed here in t...

Immunodiagnosis of Human Fascioliasis by Elisa Using Excretory–Secretory Products as Antigen

Background: Different immunological methods are used for the serodiagnosis of Fasciola hepatica infections, however, they have limited specificity and/or sensitivity.Objective: To improve the specificity of ELISA using a partially modified method for preparation of excretory-secretory (ES) antigens.Methods: Studied groups were as follows: 75 patients with parasitological evidence of fascioliasi...
