| biology of crassicutis cichlasomae, a parasite of cichlid fishes in mexico and central america. | field study on the biology of crassicutis cichlasomae manter, 1936 (digenea: homalometridae) was carried out in a small swamp in a limestone factory near mérida, yucatán, mexico. aquatic snails, littorina (littoridinopis) angulifera, harbouring c. cichlasomae rediae, cercariae and metacercariae, served both as the first and second intermediate hosts. feeding experiments confirmed the conspecificity of metacercariae from naturally infected snails with adults from naturally infected fish. gravid c ... | 1995 | 7622794 |
| cenotes (sinkholes) of the yucatan peninsula, mexico, as a habitat of adult trematodes of fish. | examination of a total of 581 fish specimens of 15 species from 39 cenotes (sinkholes) in the yucatan peninsula, southeastern mexico, revealed the presence of 10 species of adult trematodes. these were as follows: saccocoelioides sogandaresi lumsden, 1963, saccocoelioides sp. (family haploporidae), cichlasotrema ujati pineda et andrade, 1989 (angiodictyidae), crassicutis cichlasomae manter, 1936 (homalometridae), magnivitellinum simplex kloss, 1966 (macroderoididae), stunkardiella minima (stunka ... | 1995 | 9599426 |
| potential interactions between the intestinal helminths of the cichlid fish cichlasoma synspilum from southeastern mexico. | this study presents and analyzes positional data on 18 helminth species forming the intestinal infracommunities of 59 cichlasoma synspilum from southeastern mexico. interspecific interactions were found between 4 pairs of host specialists: crassicutis cichlasomae (digenea) with neoechinorhynchus golvani (acanthocephala), spirocamallanus rebecae (nematoda) with n. golvani, and raillietnema kritscheri (nematoda) with n. golvani. the interactions were expressed as negative correlations, positional ... | 2000 | 10958441 |
| on some trematodes parasites of fishes from paraná river. | crassicutis cichlasomae manter, 1936 is redescribed for the first time in south america and from a new host: geophagus brasiliensis (cichlidae). iheringtrema iheringi travassos, 1948 is redescribed for the first time since its original description from pseudopimelodus zungaro (pimelodidae); and new host records are referred to genarchella genarchella travassos et al., 1928, and to parspina argentinensis (szidat, 1954). other reported species are: microrchis oligovitellum lunaschi, 1987, neoclado ... | 2002 | 11706574 |
| description of a new species of crassicutis manter, 1936, parasite of cichlasoma beani jordan (osteichthyes: cichlidae) in mexico, based on morphology and sequences of the its1 and 28s ribosomal rna genes. | a new species of crassicutis manter, 1936 is described from the sinaloan cichlid cichlasoma beani (jordan) (osteichthyes: cichlidae) in the upper río santiago basin. crassicutis choudhuryi n. sp. differs from most of the other nominal species by having testes located in a symmetrical position. the only other species of the genus that includes some specimens exhibiting this trait is crassicutis intermedius (szidat 1954), a species found in 5 species of siluriforms and 1 species of characiform in ... | 2008 | 18372648 |
| phylogenetic analysis of nuclear and mitochondrial dna reveals a complex of cryptic species in crassicutis cichlasomae (digenea: apocreadiidae), a parasite of middle-american cichlids. | we obtained nuclear its-1 and mitochondrial cox1 sequences from 225 crassicutis cichlasomae adults collected in 12 species of cichlids from 32 localities to prospect for the presence of cryptic species. this trematode is commonly found in species of cichlids over a wide geographic range in middle-america. population-level phylogenetic analyses of its-1 and cox1, assessments of genetic and haplotype diversity, and morphological observations revealed that c. cichlasomae represents a complex of sev ... | 2010 | 19853608 |
| discordant genetic diversity and geographic patterns between crassicutis cichlasomae (digenea: apocreadiidae) and its cichlid host, "cichlasoma" urophthalmus (osteichthyes: cichlidae), in middle-america. | genetic analyses of hosts and their parasites are key to understand the evolutionary patterns and processes that have shaped host-parasite associations. we evaluated the genetic structure of the digenean crassicutis cichlasomae and its most common host, the mayan cichlid "cichlasoma" urophthalmus, encompassing most of their geographical range in middle-america (river basins in southeastern mexico, belize, and guatemala together with the yucatan peninsula). genetic diversity and structure analyse ... | 2013 | 23859473 |
