Participation of metanauplii and juvenile individuals of Artemia parthenogenetica (Branchiopoda) in the circulation of avian cestodes
Parasitology Research, 2011Co-Authors: Stella Redón, Francisco Amat, Francisco Hontoria, Gergana P. Vasileva, Pavel N. Nikolov, Boyko B. GeorgievAbstract:Adult crustaceans of the genus Artemia (brine shrimps) are intermediate hosts in the life cycle of cestode species parasitic in aquatic birds as their definitive hosts. However, there are no data on the role of larval and juvenile brine shrimps in the transmission of avian helminth parasites. In order to examine the possible role of early developmental stages (nauplii, metanauplii and juveniles) of Artemia for the circulation of avian cestodes, the natural cestode infection in the population of Artemia parthenogenetica from La Mata Lagoon, Mediterranean coast of Spain, was studied. Metacestodes (Cysticercoids) of four cestode species were recorded in adult brine shrimps: Flamingolepis liguloides and Flamingolepis flamingo (hymenolepidids parasitic in flamingos), Confluaria podicipina (a hymenolepidid species parasitic in grebes) and Eurycestus avoceti (a dilepidid species parasitic in avocets, stilts, plovers and, to a lesser extent, in flamingos). No Cysticercoids were found in nauplii. Two species, F. liguloides and F. flamingo , were found in metanauplii and juvenile brine shrimps. Only 36.3% of the Cysticercoids of F. liguloides occurred in adult brine shrimps; the remaining 63.7% were parasitic in metanauplii (39.6%) and juveniles (24.1%). Similarly, the metacestodes of F. flamingo were also distributed among various age groups: in adults (44.4% of Cysticercoids), juveniles (27.8%) and metanauplii (27.8%). These results indicate that the early developmental stages of Artemia have an important role for the circulation of certain parasite species. No Cysticercoids of C. podicipina and E. avoceti were recorded in larval and juvenile brine shrimps. The selective infestation of larval brine shrimps with flamingo parasites is probably associated with the feeding behaviour of definitive hosts, which are filtering predators; in contrast, grebes and waders pick brine shrimps individually one by one. The possible underlying mechanism for selective infestation of metanauplii and adults by certain cestode species is associated with the size of parasite eggs, allowing only cestode species with small eggs to be ingested by larval brine shrimps.

records of Cysticercoids of fimbriarioides tadornae maksimova 1976 and branchiopodataenia gvozdevi maksimova 1988 cyclophyllidea hymenolepididae from brine shrimps at the mediterranean coasts of spain and france with a key to cestodes from artemia spp from the western mediterranean
Acta Parasitologica, 2009Co-Authors: Gergana P. Vasileva, Stella Redón, Francisco Amat, Pavel N. Nikolov, Boyko B. Georgiev, Marta I. Sánchez, Thomas LenormandAbstract:Cysticercoids of two cestode species isolated from brine shrimps from the Mediterranean coasts of Spain and France are described. Fimbriarioides tadornae Maksimova, 1976 (adults known as parasites of Tadorna tadorna) was recorded from Artemia parthenogenetica and A. franciscana from Spain (Bras del Port and River Ebro Delta, respectively), and from A. franciscana from Aigues-Mortes, France (new geographical record). Branchiopodataenia gvozdevi (Maksimova, 1988) (adults known as parasites of Larus genei) was recorded from A. parthenogenetica (Bras del Port, Spain), A. salina (San Pedro del Pinatar, Spain) and A. franciscana (River Ebro Delta, Spain); this is the first record of the species in Europe. An illustrated key to Cysticercoids of 12 cestode species from Artemia spp. from the Western Mediterranean is proposed.

cestodes from artemia parthenogenetica crustacea branchiopoda in the odiel marshes spain a systematic survey of Cysticercoids
Acta Parasitologica, 2005Co-Authors: Boyko B. Georgiev, Gergana P. Vasileva, Pavel N. Nikolov, Marta I. Sánchez, Andy J. Green, Radka S MavrodievaAbstract:A total of 3,300 specimens of brine shrimps Artemia parthenogenetica from the Odiel Marshes, Huelva Province, SW Spain, were studied during several seasons of 2002 and 2003 for the presence of cestode infections. Cysticercoids were found in 26.8% of brine shrimps. Eight cestode species were recorded, i.e., Hymenolepididae: Flamingolepis liguloides (adults parasitic in flamingos) with prevalence (P) 18.5%, mean intensity (MI) 1.48 and mean abundance (MA) 0.28; F. flamingo (adults parasitic in flamingos), P 0.9%, MI 1.03, MA 0.01; Confluaria podicipina (adults parasitic in grebes), P 6.5%, MI 1.42, MA 0.09; Wardium stellorae (adults parasitic in gulls), P 0.2%, MI 1.00, MA 0.002; Dilepididae: Eurycestus avoceti (adults parasitic in waders and flamingos), P 2.7%, MI 1.08, MA 0.03; Anomotaenia sp., probably A. microphallos (adults parasitic in waders), P 0.8%, MI 1.04, MA 0.01; A. tringae (adults parasitic in waders), P 2.2%, MI 1.01, MA 0.02; Progynotaeniidae: Gynandrotaenia stammeri (adults parasitic in flamingos), P 0.6%, MI 1.00, MA 0.01. The Cysticercoids are described and accompanying illustrations are presented. This study provides the first record of Anomotaenia tringae in an intermediate host and the first records of C. podicipina, E. avoceti, A. tringae and G. stammeri in Spain.
