Blood samples were collected opportunistically at routine post mortem examination from 199 sheep which came from 152 flocks. The location of each submitting flock was mapped. Sera were tested using a goose blood haemagglutination inhibition assay for louping ill virus. There was an animal level prevalence of 8.5%, and a flock level prevalence of 9.8%. The greatest proportion of seropositive ani...

A sensitive immunological assay for plasminogen and/or plasmin was developed by using a haemagglutination inhibition technique. Plasma and the corresponding euglobulin fraction of healthy subjects and of patients with hyperfibrinolysis (liver cirrhosis, thrombolytic treatment) were assayed for plasminogen using immunological and caseinolytic techniques. In hyperfibrinolytic states discrepancies...

There is still some confusion about the ability of monkey and human gonadotrophins to cross react in immunological systems. McGarry & Beck (1963), using a haemagglutination inhibition technique, found a cross reaction between antisera to human fsh and monkey fsh. They also found a similar cross reaction with lh. Neill, Peckham & Knobil (1967), Bagshawe, Orr & Godden (1968) and Faiman, Ryan, Gre...

This paper presents further evidence of the sensitivity and reproducibility of ELISA for the detection of rubella antibody. This test can also be extended to include the diagnosis of recent rubella infections once the index of significance has been computed based on the estimated ELISA ratio of absorbance between the acute and convalescent serum samples. There is a greater than 90% agreement wh...

In the current outbreak, dengue type 1 has been identified in several cases. Initial interpretations of antibody levels (ie. haemagglutination inhibition antibody titres) suggested that dengue types 3 and 4 were causing the current outbreak. Since then, however, more sensitive tests (nucleic acid amplification and virus isolation) have identified only type 1 dengue in the samples, although not ...

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...
