A comparison of the indirect haemagglutination test (IHAT) with the dye test (DT) in 23 infants with congenital toxoplasmosis showed that in the early part of the first year of life the IHAT titres were nearly all lower than the DT titres. In six cases the IHAT was negative or the titre was so low that the cases could have been missed in routine screening. Later in the first year the IHAT titre...

Lymphogranuloma venereum (L.G.V.) has been known for many years under such names as lymphogranuloma inguinale, lymphopathia venereum, climatic bubo, poradenitis, or Nicolas and Favre's disease. Frei (1925) introduced a skin test, for long regarded as specific, using a treated suspension of pus from a bubo as antigen. With this he obtained in patients with lymphogranuloma venereum a papular reac...

Brucellosis is an infectious disease that affects many organ systems. Osteoarticular involvement, especially spondylitis, is the most common complication of brucellosis, but psoas abscess is very rare.

I have assumed some background knowledge and elected to di...

results in this setting, detection rate of the disease is 34.86%, if the high normal titer for the wrights test titer assumed 1/80 and is 44.95% if the titer assumed 1/40, while elisa test had detection rate of 58.72% for those suspicious cases. furthermore, the detection rate for diagnosis of active brucellosis with 2me tests was 17.54% with high normal titer of 1/80 and was 59.64% with a high...
