“…The phylogenetic trees were useful, however, in providing preliminary hypotheses for how the various clades were related to one another (see the paragraph below). Relative to other paramphistomoid molecular phylogenetic studies involving specimens from African ruminants and snails, we recovered five out of the six previously reported taxa from Kenya, Egypt and Tanzania noted by Lotfy et al ( 2010 ), three of the three identified taxa from Zimbabwe, Zambia and Botswana (Dube et al 2015 ) and one of the two identified taxa from Algeria (Titi et al 2014 ). The extent of overlap among specimens recovered from all four studies suggests that at least some of the species have broad distributions in Africa.…”

“…The most common paramphistomoid genus we collected was Calicophoron (40 out of the 120 specimens examined), and the most abundant species was Calicophoron microbothrium which is transmitted by bulinid snails. This species is the most geographically widespread paramphistome in Africa, its presence confirmed with molecular markers from Egypt, Kenya, Tanzania, Zambia, Zimbabwe, South Africa, Algeria and Botswana (Lotfy et al 2010 ; Titi et al 2014 ; Dube et al 2015 ). Given the difficulties in discriminating this species from others based on morphology alone, the broad geographic distribution, and the diversity of different bulinid snails reported as hosts, this species is a good candidate for further inspection as a possible complex of cryptic species.…”

“…The number of studies that use molecular techniques to provide assessments of the diversity of paramphistomoids have in general been limited, especially so for African species (Lotfy et al 2010 ; Mansour et al 2014 ; Sibula et al . 2014 ; Titi et al 2014 ; Dube et al 2015 ).…”

Loads of trematodes: discovering hidden diversity of paramphistomoids in Kenyan ruminants

SUMMARYParamphistomoids are ubiquitous and widespread digeneans that infect a diverse range of definitive hosts, being particularly speciose in ruminants. We collected adult worms from cattle, goats and sheep from slaughterhouses, and cercariae from freshwater snails from ten localities in Central and West Kenya. We sequenced cox1 (690 bp) and internal transcribed region 2 (ITS2) (385 bp) genes from a small piece of 79 different adult worms and stained and mounted the remaining worm bodies for comparisons with available descriptions. We also sequenced cox1 and ITS2 from 41 cercariae/rediae samples collected from four different genera of planorbid snails. Combining morphological observations, host use information, genetic distance values and phylogenetic methods, we delineated 16 distinct clades of paramphistomoids. For four of the 16 clades, sequences from adult worms and cercariae/rediae matched, providing an independent assessment for their life cycles. Much work is yet to be done to resolve fully the relationships among paramphistomoids, but some correspondence between sequence- and anatomically based classifications were noted. Paramphistomoids of domestic ruminants provide one of the most abundant sources of parasitic flatworm biomass, and because of the predilection of several species use Bulinus and Biomphalaria snail hosts, have interesting linkages with the biology of animal and human schistosomes to in Africa.

“…For example, Calicophoron calicophorum is the most common species in Australia whilst Paramphistomum cervi is described as the most common species in countries as far apart as Pakistan and Mexico [ 14 , 10 , 9 , 6 ]. In Mediterranean and temperate regions of Algeria and Europe, Calicophoron daubneyi predominates [ 15 , 1 , 16 ], and it has recently also been recognized as the main rumen fluke in the British Isles [ 17 , 18 ]. Traditionally, rumen fluke species were identified on the basis of morphology, but microscopic methods are increasingly being replaced with molecular typing methods, including PCR and sequencing approaches targeting the ITS-2 or tRNA-Thr/Cox1 regions [ 17 , 19 , 18 ].…”

An abattoir survey was performed in the French Melanesian archipelago of New Caledonia to determine the prevalence of paramphistomes in cattle and deer and to generate material for molecular typing at species and subspecies level. Prevalence in adult cattle was high at animal level (70% of 387 adult cattle) and batch level (81%). Prevalence was lower in calves at both levels (33% of 484 calves, 51% at batch level). Animals from 2 of 7 deer farms were positive for rumen fluke, with animal-level prevalence of 41.4% (29/70) and 47.1% (33/70), respectively. Using ITS-2 sequencing, 3 species of paramphistomes were identified, i.e. Calicophoron calicophorum, Fischoederius elongatus and Orthocoelium streptocoelium. All three species were detected in cattle as well as deer, suggesting the possibility of rumen fluke transmission between the two host species. Based on heterogeneity in ITS-2 sequences, the C. calicophorum population comprises two clades, both of which occur in cattle as well as deer. The results suggest two distinct routes of rumen fluke introduction into this area. This approach has wider applicability for investigations of the origin of rumen fluke infections and for the possibility of parasite transmission at the livestock-wildlife interface.

Peu de données sont disponibles concernant le traitement de la pathologie liée à la forme immature de Calicophoron daubneyi. Pour étudier l’efficacité du closantel dans cette indication, 10 agneaux placés pendant 42 jours sur une parcelle connue comme étant infestée par C. daubneyi ont ensuite été répartis en deux lots, témoin et traité, puis autopsiés 7 à 10 jours après traitement. Les parasites présents dans le duodénum ont été dénombrés en différenciant les formes libres et les formes intramuqueuses. La réduction du nombre de parasites libres (61 %) s’est avérée très variable et non-significative. En revanche, la réduction du nombre de parasites intramuqueux (56 %) a été très significative (p = 0,002). Etant donné le pouvoir pathogène des larves intramuqueuses, le closantel pourrait être utile aux animaux récemment infestés.
