Cutaneous leishmaniasis in Sri Lanka. An imported disease linked to the Middle East and African employment boom.

Cutaneous leishmaniasis acquired by two Sri Lankan nationals while they were employed in Iraq and Northern Nigeria respectively constitutes examples of an imported disease related to the 'Middle East and African employment boom'. In both cases the diagnoses were confirmed by demonstrating the parasites in smears from the lesions and in tissue sections, and by culturing the parasites in vitro. Since leishmaniasis, neither visceral nor cutaneous is prevalent in Sri Lanka the risks of 'introduced' diseases is discussed here in the context of these two cases.

Alteration in Aedes togoi susceptibility to Brugia pahangi microfilariae induced by Aedes albopictus thoracic homogenate.

Refractoriness to Brugia pahangi microfilarial infection could be induced in the normally susceptible Aedes togoi mosquitoes by intrathoracic injection with crude thoracic homogenate of the refractory Aedes albopictus mosquitoes. The crude thoracic homogenate contained three Sephadex G-200 protein profiles of which the first profile showed strongest inhibition to the parasite development.
