The diagnosis of occult staphylococcal infection of bone is often difficult. Two cases are presented that illustrate the use of the anti-alpha haemolysin titration. In the second case this test appears to have been of value as a guide to effective chemotherapy. Such cases are now infrequent and we publish these results in the hope that further knowledge of the efficiency of this test may be sou...

A novel serological test, IPAzyme Chlamydia (Savyon Diagnostics Ltd., Beer Sheva, Israel), was compared with an enzyme immunoassay (EIA) for the ability to detect serum immunoglobulin G and A antibodies in the diagnosis of acute chiamydial pelvic inflammatory disease. In comparison with cell culture, which is the "gold standard," IPAzyme Chlamydia and EIA exhibited sensitivities of 63 and 68% a...

A rapid serodiagnostic test for the diagnosis of paratrachoma (TRIC ophthalmia neonatorum, inclusion conjunctivitis, TRIC punctate keratoconjunctivitis, and trachoma of sexually transmitted origin) has been developed. The technique is based on using a modified micro-immunofluorescence test for detecting antichlamydial IgG and IgM in the blood and IgG and IgA in tears. The blood samples are coll...

The latex slide test (L.S.T.) has been shown to be simple to perform and easy to read. It gives results comparable with the more complicated serological procedures used in the diagnosis of rheumatoid arthritis.In 603 cases the L.S.T. and differential agglutination test gave a high degree of correlation. There were only four discrepancies between the two tests. The L.S.T. is the more practicable...

A COMPARATIVE STUDY OF AN ELISA TEST AND AN INDIRECT IMMUNOFLUORESCENCE TEST FOR SEROLOGICAL DIAGNOSIS OF BABESIA BOVIS INFECTION. Detection of antibodies to Babesia bovis in cattle is essential for the understanding of the epidemiology of babesiosis and this study was concerned with comparing the indirect fluorescent antibody with the ELISA. Both assays gave rise to 100% sensitivity whilst the...

An indirect fluorescent antibody technique has been developed for the serological diagnosis of gonorrhea. The selected strain(s) of Neisseria gonorrhoeae possesses a heat-labile surface antigen (L-antigen). Sera are diluted 1:10, and an aliquot is hear inactivated at 59 C for 30 min. The treated and untreated aliquots are then examined for human immunoglobulin G anti-L-antigen. In a prelimiary ...

because of possible increase in the incidence of brucellosis in the city ghom , serological and bacteriological studies were conducted to investigate the rate of infection in this city. a total of 819 blood samples from human , “suspected” cases were investigated (serologically) 121 of these were positive for brucellosis ,(14/6%).of 182 samples of milk collected from cattle 50 were positive (27...

Ten to fifteen percent of patients with myasthenia gavis (MG) have an underlying thymoma. Such patients do less well and it may be important to detect them early. Conventional tests for thymoma such as immunofluorescent demonstration of skeletal muscle antibodies and CT scanning of the anterior mediastinum may give false positive and false negative results. We have attempted to validate a repor...
