Four variants of merozoite surface protein 2 (MSP-2) of Plasmodium falciparum were used in serology to examine whether changes in repeat units affect its recognition by antibodies during infection with parasites of known MSP-2 types. The results indicate that variation in MSP-2 repeats may represent a mechanism for parasite immune evasion.

In a previous paper, Dewhurst (in press) surveyed the incidence, course, and natural history of the neurosyphilitic psychoses by analysing the clinical histories of 91 patients whose illnesses necessitated their admission to mental hospitals between 1950 and 1965. Selection bias was avoided as only patients requiring treatment in mental hospitals were included. In spite of the advanced stage of...

The diagnostic value of toxoplasma serology in ocular disease was evaluated in the following groups of patients: (I) uveitis cases of various causes (n = 291); (II) consecutive posterior and panuveitis patients (n = 60); (III) patients with definite congenital and ocular toxoplasmosis (n = 8); (IV) cases of clinical ocular toxoplasmosis (n = 25); and control patients with uveitis of non-toxopla...

Serological tests for syphilis are of fundamental importance in studying treponemal infections in experimental animals. Non-human primate species have been increasingly employed in treponematology in the past few years. However, Fribourg-Blanc, Niel, and Mollaret (1963, 1966) found an endemic treponeme in cynocephalus monkeys from Guinea. Sepetjian, Guerraz, Salussola, Thivolet, and Monier (196...

ent ways to produce Coombs serum are described with little or no attempt to define how important they are in the overall scheme of human blood and serum groups. But perhaps because this is a reference book it is more important to detail everything than to discuss those areas that the authors deem important. Some subjects, the Lewis, the I, i, and the leukocyte groups, for example, are discussed...

Abstract Introduction/Objective Benchmarking establishes baseline laboratory utilization patterns across health systems. Nicholas et al. (2021) recently evaluated the use of test volume ratios to identify intervention targets at VA hospitals. We aim investigate potential differences reported with those non-VA Methods/Case Report Using Vizient® Clinical Data Base permission from Vizient, Inc. (A...
