The non-immunoglobulin component of human milk responsible for the inhibition of Escherichia coli cell adhesion (haemagglutination) mediated by colonisation factor antigen 1 (CFA1) was determined by chromatographic fractionation of human whey proteins with Sephadex G-200, DEAE cellulose and heparin-sepharose. Pure free secretory component (fSC) and pure lactoferrin (Lf) were isolated and both c...

A passive haemagglutination test, using sheep red blood cells sensitised with Salmonella typhi lipopolysaccharide, was compared with the Widal test for the serological diagnosis of typhoid fever in an endemic area. The results obtained on sera from 152 patients with bacteriologically confirmed typhoid and 183 patients who did not have typhoid were analysed in terms of sensitivity, specificity, ...

objective: the immunomodulatory effect of geranial, geranial acetate, gingerol, and eugenol essential oils were evaluated by studying humoral and cell-mediated immune responses. materials and method: the essential oils were evaluated for immunomodulatory activity in in vivo studies, using rats as the animal model. the essential oils were tested for hypersensitivity and hemagglutination reaction...

The introduction of the treponemal immobilization (TPI) test by Nelson and Mayer (1949) provided the first verification test for syphilis which proved fully acceptable to the clinician. After 20 years it is still accepted by a large body of opinion as the verification test of choice for the diagnosis of latent and late syphilis. The test's characteristic of becoming positive towards the end of ...
