Leishmania (Viannia) shawi Lainson, Braga, de Souza, Pόvoa, Ishikawa & Silveira, 1989, was originally recorded from monkeys (Cebus apella and Chiropotes satanas), sloths (Choloepus didactylus and Bradypus tridactylus) and coatis (Nasua nasua) and the sandfly, Lutzomyia whitmani. With a panel of Leishmania specific monoclonal antibodies, it was found that 30.5 % of the Leishmania strains from patients, who had contracted cutaneous leishmaniasis in Pará State, were similar, but not identical to L. (V.) guyanensis. The enzyme profiles of 18 of these strains were determined, and it was found that 12 isolates belonged to the same zymodeme as the type strain of L. (V.) shawi. The other 6 belonged to a second L. (V.) shawi zymodeme that only differed from the other by having a slightly faster PEP band. These results are the first records of infections of L. (V.) shawi in man and suggest that this parasite is probably common in areas of Pará State to the south of the Amazon River.
Résumé
Leishmania (Viannia) shawi Lainson, Braga, de Souza, Pόvoa, Ishikawa & Silveira, 1989 a été décrite initialement chez des singes (Cebus apella et Chiropotes satanas), des paresseux (Choloepus didactylus et Bradypus tridactylus), des coatis (Nasua nasua) et le phlébotome Lutzomyia whitmani. L’utilisation d’anticorps monoclonaux spécifiques pour le genre Leishmania a montré que 30,5 % des souches de Leishmania isolées d’individus ayant contracté la leishmaniose cutanée dans l’État du Pará, sont semblables mais non identiques à L. (V.) guyanensis. Les profils enzymatiques de 18 parmi ces isolats ont été étudiés et 12 se sont révélés identiques à la souche de référence de L. (V.) shawi. Six isolats appartiennent au deuxième zymodème de L. (V.) shawi avec cependant la bande de l’enzyme PEP légèrement plus rapide. Ce parasite, probablement commun dans les zones de l’État du Pará situées au sud de l’Amazone, est associé pour la première fois à des infections humaines.
