Notes on the occurrence of Trypanosoma sp. (Kinetoplastida: Trypanosomatidae) in freshwater fishes from South Africa.

Leptoconops nosopheris sp. n. (Diptera: Ceratopogonidae) and Paleotrypanosoma burmanicus gen. n., sp. n. (Kinetoplastida: Trypanosomatidae), a biting midge--trypanosome vector association from the Early Cretaceous.

Leptoconops nosopheris sp. n. (Diptera: Ceratopogonidae) is described from a blood-filled female biting midge in Early Cretaceous Burmese amber. The new species is characterized by a very elongate terminal flagellomere, elongate cerci, and an indistinct spur on the metatibia. This biting midge contained digenetic trypanosomes (Kinetoplastida: Trypanosomatidae) in its alimentary tract and saliva...

Phylogeny of Trypanosomatidae and Bodonidae (Kinetoplastida) based on 18S rRNA: evidence for paraphyly of Trypanosoma and six other genera.

Phylogenetic analysis of 18S rRNA sequences from the families Trypanosomatidae and Bodonidae (Eugelenozoa: Kinetoplastida) was conducted using a variety of methods. Unlike previous analyses using unrooted trees and/or smaller numbers of sequences, the analysis did not support monophyly of the genus Trypanosoma, which includes the major human parasites T. cruzi (cause of Chagas' disease) and T. ...

Massive experimental inoculation of Trypanosoma rangeli (Kinetoplastida, Trypanosomatidae) in Rhodnius neglectus Lent, 1954 (Hemiptera, Reduviidae) and Mus musculus.

Trypanosoma (Megatrypanum) saloboense n. sp. (Kinetoplastida: Trypanosomatidae) parasite of Monodelphis emiliae (Marsupiala: Didelphidae) from Amazonian Brazil.

Trypanosoma (Megatrypanum) soloboense n. sp., is described in the Brazilian opossum Monodelphis emiliae (Thomas, 1912) from primary forest in the Salobo area of the Serra dos Carajás (6 degrees S, 50 degrees 18' W) Pará State, North Brazil. Two morphologically different trypomastigotes were noted. Slender forms, regarded as immature parasites, have a poorly developed undulating membrane adherin...

Myxobolus spp. (Myxosporea: Myxobolidea) from fishes of the Zayandeh-Rud River (Esfahan, Iran); new hosts and locality record

In a parasitic survey of the native and introduced fishes in the Zayandehrud River, 5 Myxobolus spp. were found in the gills, fins and skin of examined fish specimens. They include M. varicorhini from fin and M. samgoricus from skin of Capoeta damascina, M. musajevi from gills of Capoeta capoeta gracilis, Myxobolus cristatus from Capoeta aculeata, and M. saidovi from Alburnus sp. Data on the lo...
