A comparative study on parasites of Gadus morrhua in six regions of the North East Atlantic provides new data on parasite infection levels and the structure of the regional parasite faunas in cod with respect to the higher-level taxonomic groupings, host specificity and zoogeographical distribution of the parasites.

The present study provides fossil evidence that Neotropical sand flies were vectors of trypanosomatids in the mid-Tertiary. Lutzomyia adiketis and Paleoleishmania neotropicum are described from Dominican amber.Image:Sand fly vector in Dominican amber
A monoclonal antibody was made to uncharacterised components of Trypanosoma brucei flagella. Novel immuno-electron microscopy reveals that this antibody binds to fibres physically linking the cytoskeleton to the mitochondrion membrane.

The use of Trypanosoma rangeli trypomastigotes as antigens in serodiagnosis may avoid misdiagnosis of Chagas disease. Image:Trypanosoma rangeli blood trypomastigotes in experimentally infected mice.
The use of the stable isotope nitrogen-15 as a semen-label to study mating in the malaria mosquito Anopheles arabiensis is described. Image: Spermatozoa of An. arabiensis.
