Leishmania (Viannia) shawisp. n., a parasite of monkeys, sloths and procyonids in Amazonian brazil

Abstract

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.

“…Diferentemente das outras áreas endêmicas do Estado do Rio de Janeiro, a Lutzomyia whitmani foi à segunda espécie mais freqüente, substituindo a Lutzomyia migonei que comumente precede a Lutzomyia intermedia como a segunda espécie mais freqüente nas áreas endêmicas de LTA 6 . Apesar da baixa densidade de Lutzomyia whitmani, é importante observar que esta espécie é tida como o principal vetor de Leishmania (Viannia) braziliensis em diversas regiões do país 16 20 e associado à transmissão de Leishmania (Viannia) guyanensis e Leishmania (Viannia) shawi 13 .…”

Serological survey for Leishmania sp. infection in wild animals from the municipality of Maringá, Paraná state, Brazil

“…Since Leishmania infection and/or presence of anti-Leishmania antibodies had been already reported in Cerdocyon thous (8,9,20), Lycalopex vetulus (9,20), Cebus apella (11) and Nasua nasua (11), these animals were pinpointed as Leishmania (40) detected parasites of the Leishmania genus in this species.…”

“…Whereas Leishmania (Leishmania) chagasi has been isolated from crab-eating foxes (Cerdocyon thous), Leishmania (Viannia) lainsoni was found in pacas (Agouti paca) (8)(9)(10). Leishmania (Viannia) shawi, in turn, has been detected in capuchin monkeys (Cebus apella), bearded sakis (Chiropotes satanas), coatis (Nasua nasua) (11), three-toed sloths (Bradypus tridactylus) and two-toed sloths (Choloepus didactylus) (11). Leishmania (L.) mexicana has been found in big-eared climbing rats (Ototylomys phyllotis), blackeared rice-rats (Oryzomys melanotis), Yucatan deer-mice (Peromyscus yucatanicus) and hispid cotton rats (Sigmodon hispidus) (12).…”

Cutaneous leishmaniasis of man due toLeishmania (Viannia) shawiLainson, de Souza, Pόvoa, Ishikawa & Silveira, in Pará State, Brazil

“…

Leishmania (Viannia) shawi Lainson, Braga, de Souza, Póvoa, 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 mono clonal antibodies, it was found that 30.5 % of the Leishmania strains from patients, who had contracted cutaneous leishmaniasis in Para 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.
