“…The L. gerbilli, L. arabica and L. enriettii phenetic complexes formed by only one unit are consi dered as subsets of the type single. Although fundamental diffe rences exist between the notion of complex as used here and that established by Lainson and Shaw, 1972, a congruence of the two classifications should be noted.…”

“…27 Infectivity of parasites decreased in hamsters, even though parasites proliferated in Novy-McNeal-Nicolle agar culture that contained rabbit blood. 29 In several studies, researchers have tried to increase the infectivity of Leishmania parasites that were long-term cultured in vitro and had low infectivity. 4-6, 16 , 17, 30-33 Promastigotes of L. braziliensis were exposed to heat shock by changing the temperature of their culture from 26°C to 34°C.…”

Abstract. In vitro cultivation of Leishmania parasites plays an important role in diagnosis and treatment of leishmaniasis and in vaccine and drug development studies. Conversely, long-term cultivation of Leishmania parasites usually results in decreased infectivity potential. Some studies reported a stimulatory effect of human urine in Leishmania promastigotes. However, there is no information about the effects of urine within culture on the infectivity of Leishmania parasites. Analysis of the effect of urine have showed that proliferation indexes were significantly increased in culture medium supplemented with human urine ( L. tropica = 38.17 ± 5.12, L. donovani = 34.74 ± 5.6, L. major = 34.22 ± 4.66, and L. infantum 35.88 ± 6.40) than in controls. Infection indexes were 13 ± 1.7 for L. tropica , 55 ± 2.2 for L. infantum , 41 ± 3.14 for L. donovani , and 49 ± 3.26 for L. major . Our results showed that human urine increased the infectivity and proliferation of Leishmania parasites.* Address correspondence to Adil M. Allahverdiyev,

“…What was thought to probably be the same parasite was later isolated from the viscera of C. didactylus, from Acará, Para, by Lainson and Shaw (1972). This was undoubtedly a Leishmania species, which these authors later considered to «... differ from L. b. braziliensis and L. chagasi... », and to be «... closest to L. b. guyanensis... » (Lainson andShaw, 1979, 1987).…”

SUMMARY. Leishmania (Viannia) shawi sp. n., is described from the monkeys Cebus apella and Chiropotes satanus, the sloths Choloepus didactylus and Bradypus tridactylus, the procyonid Nasua nasua, and the phlebotomine sandfly Lutzomyia whitmani, all from primary forest in the State of Par, north Brazil. L. (V.) shawi is variably distinguished from all other known species within the subgenus Viannia by a combination of biological, biochemical and serological cha racters, as revealed by studies on morphology, isoenzyme profiles, kDNA buoyant densities and monoclonal antibodies.
