Because of its relative ease of operation the haemagglutination inhibition (HAI) test has been widely used in diagnostic virus serology for detecting specific antibody to haemagglutinating viruses. Erythrocyte species of animal origin are used more frequently than human group 'O' cells in haemagglutination (HA) and HAI tests because they are usually more sensitive to agglutination by certain vi...

Sera from 48 Kenyan Africans with rheumatoid arthritis, 43 patients with other diseases, and 98 blood donors were tested for the presence of rheumatoid factor by latex fixation tests using human European, human African, and rabbit immunoglobulin, and a sheep cell haemagglutination test. In the patients with rheumatoid arthritis the frequency of rheumatoid factor was comparable to that reported ...

A rapid whole cell protein antigen (iron restricted Mycoplasma gallisepticum) based latex agglutination test (LAT) was developed to detect the presence of antiMycoplasma gallisepticum antibodies in the sera of poultry affected with mycoplasmosis. The test was found to be sensitive, specific and accurate in comparison with Haemagglutination Inhibition (HI) test. The rapidity, simplicity and econ...

AIMS To characterise a novel strain of adenovirus (Ad) type Ad8 (genome type Ad8I) involved in an epidemic keratoconjunctivitis (EKC) outbreak in Hiroshima city using serological testing and sequence analysis of the fibre and hexon gene. METHODS A neutralisation test (NT) was performed in microtitre plates containing a confluent monolayer of A549 cells using 100 tissue culture infectious dose...

Background and Aims: Herpes simplex virus (HSV) is responsible for several significant human viral diseases, with severity ranging from subclinical to fatal infection. Herpes simplex virus type 2 (HSV2) infections are more commonly seen in association with the genitalia and surrounding areas, and can be transmitted to newborns during childbirth. Generalized infections in newborns are also predo...

The immunomodulatory activity of Cod liver oil (CLO) was evaluated by mice lethality test, carbon clearance assay, neutrophil adhesion test, cyclophosphamide-induced neutropenia, indirect haemagglutination test and effect on serum immunoglobulin levels. CLO was administered orally at a dose of 0.5 g/kg or 1 g/kg body weight. In mice lethality test, low dose of CLO (0.5 g/kg, po) produced 40% de...

  Humoral immune response of vaccine-I (supermatent from sonicated sporulated oocyst), vaccine –II (sediment from sonicated sporulated oocyst) and vaccine –III (un-sonicated sporulated oocyst) against conccidiosis in chickens was determined by indirect haemagglutination (IHA) test. IHA antibody titre was significantly higher (p
