| blood parasites of amphibians from sichuan province, people's republic of china. | two hundred forty-six amphibians from sichuan province, people's republic of china, were examined for blood parasites between april and june 1990. six trypanosome species were found, 2 of which were not identified because of poor material. trypanosoma rotatorium (sensu mayer, 1843) was found in rana limnocharis and rana nigromaculata. trypanosoma chattoni and a t. rotatorium-like species were found in bufo gargarizans. a sphaeromastigote similar to trypanosoma tsunezomiyatai was seen in r. limno ... | 1993 | 8501591 |
| first record of trypanosoma chattoni in brazil and occurrence of other trypanosoma species in brazilian frogs (anura, leptodactylidae). | the present study provides the first record of trypanosoma chattoni mathis and leger, 1911, in a new host, leptodactylus fuscus schneider, 1799 (anura, leptodactylidae), and the occurrence of trypanosoma rotatorium-like species in leptodactylus chaquensis cei, 1950. the anurans were captured in the state of mato grosso, brazil. blood samples were obtained by cardiac puncture, and blood smears were examined for the presence of hemoparasites. the trypanosoma rotatorium-like species in this study r ... | 2008 | 18372634 |
| Pathological Study of Blood Parasites in Rice Field Frogs, Hoplobatrachus rugulosus (Wiegmann, 1834). | One hundred and forty adult rice field frogs, Hoplobatrachus rugulosus (Wiegmann, 1834), were collected in Srakaew province, Thailand. For blood parasite examination, thin blood smears were made and routinely stained with Giemsa. The results showed that 70% of the frogs (98/140) were infected with 5 species of blood parasites, including a Trypanosoma rotatorium-like organism, Trypanosoma chattoni, Hepatozoon sp. a, Hepatozoon sp. b, and Lankesterella minima. Pathological examination of the liver ... | 2011 | 21918731 |
| sexual differences in prevalence of a new species of trypanosome infecting túngara frogs. | trypanosomes are a diverse group of protozoan parasites of vertebrates transmitted by a variety of hematophagous invertebrate vectors. anuran trypanosomes and their vectors have received relatively little attention even though these parasites have been reported from frog and toad species worldwide. blood samples collected from túngara frogs (engystomops pustulosus), a neotropical anuran species heavily preyed upon by eavesdropping frog-biting midges (corethrella spp.), were examined for trypanos ... | 2016 | 26977404 |
| phylogenetic position of the giant anuran trypanosomes trypanosoma chattoni, trypanosoma fallisi, trypanosoma mega, trypanosoma neveulemairei, and trypanosoma ranarum inferred from 18s rrna gene sequences. | phylogenetic relationships within the kinetoplastid flagellates were inferred from comparisons of small-subunit ribosomal rna gene sequences. these included 5 new gene sequences, trypanosoma fallisi (2,239 bp), trypanosoma chattoni (2,180 bp), trypanosoma mega (2,211 bp), trypanosoma neveulemairei (2,197 bp), and trypanosoma ranarum (2,203 bp). trees produced using maximum-parsimony and distance-matrix methods (least-squares, neighbor-joining, and maximum-likelihood), supported by strong bootstr ... | 2002 | 12099428 |
| anuran trypanosomes: phylogenetic evidence for new clades in brazil. | trypanosomes of anurans and fish are grouped into the aquatic clade which includes species isolated from fish, amphibians, turtles and platypus, usually transmitted by leeches and phlebotomine sand flies. trypanosomes from brazilian frogs are grouped within the aquatic clade with other anuran trypanosome species, where there seems to be coevolutionary patterns with vertebrate hosts and association to brazilian biomes (atlantic forest, pantanal and amazonia rainforest). we characterised the anura ... | 2015 | 25862033 |
| phylogenetic relationships among anuran trypanosomes as revealed by riboprinting. | twenty trypanosome isolates from anura (frogs and toads) assigned to several species were characterized by riboprinting-restriction enzyme digestion of polymerase chain reaction amplified small subunit ribosomal rna genes. restriction site polymorphisms allowed distinction of all the recognized species and no intraspecific variation in riboprint patterns was detected. phylogenetic reconstruction using parsimony and distance estimates based on restriction fragment comigration showed trypanosoma c ... | 2006 | 7728144 |
