Phlebotomus sergenti, a vector of Leishmania tropica in Saudi Arabia.
Cette etude confirme que dans les regions montagneuses du sud-ouest de l'Arabie Saoudite, P. sergenti peut etre infecte par un L. tropica qui presente des caracteristiques biochimiques en commun avecExpand
Somaclonal and gametoclonal variation
For several years it has been recognized that introduction of plant cells into culture results in genetic changes. These genetic alterations have been recovered in the plants regenerated from cellExpand
Mixed leishmanial infections in Rhombomys opimus: a key to the persistence of Leishmania major from one transmission season to the next.
Isoenzyme identification of 664 isolates obtained from wild-caught R. opimus showed that L. turanica infections in R.Opimus promote the persistence of L. major between transmission seasons, and in hyper- and meso-endemic foci, the proportion ofL. Expand
Leishmania infecting man and wild animals in Saudi Arabia. 2. Leishmania arabica n. sp.
Leishmania arabica n. sp., found in the rodent Psammomys obesus in the Eastern Province of Saudi Arabia, is described. This parasite, which has also been found in a feral dog in the same area, isExpand
Studies on the leishmaniases in the Sudan. 2. Clinical and parasitological studies on cutaneous leishmaniasis.
In the Omdurman Hospital for Tropical Diseases, Sudan, from 6 October to 1 December 1986, 736 patients with cutaneous leishmaniasis (CL) were studied and patients with severe lesions were given 3 to 4 weeks' treatment with intravenous Pentostam, to which all except 2 responded satisfactorily with minimal side effects.

This review focuses on the unique variation generated by this technique and the current use of somaclonal variation to develop new plant varieties. Expand
Cutaneous leishmaniasis in south-western Ethiopia: Ocholo revisited.
The borough of Ocholo, on the western side of the Ethiopian Rift Valley, is an endemic focus for Leishmania aethiopica infection and has been surveyed thrice between 1987 and 1990, where Phlebotomus pedifer was found to be the major, and possibly the only, vector for L. aETHiopica. Expand
Evidence of genetic recombination in Leishmania.
Isoenzyme analysis and molecular karyotyping of cloned organisms indicated that the putative hybrids are distinct from other species of Leishmania, and possess characteristics of both L. major and L. arabica. Expand
Single Gene Mutations in Tomato Plants Regenerated from Tissue Culture
The recovery of single gene mutations is evidence that plant tissue culture can be mutagenic in Lycopersicon esculentum. Expand
Trypanosoma brucei: Miniature anion-exchange centrifugation technique for detection of low parasitaemias: Adaptation for field use.
The AEC method has been shown to be highly sensitive and to fulfil the first essential criteria for exploitation in the field, namely, that it can be operated in the open air under tropical conditions, and that an adequate number of subjects can be examined in a normal working day at an acceptable cost.
