Influence of [beta]-glucan on innate immunity and resistance of Lutjanus guttatus to an experimental infection of dactylogyrid monogeneans
of the siluriform fishes of the old world.
A bibliometric survey (Machado, 2007; Macias-Chapula, 1998) of the main markers used in phylogenetic analyses on monogeneans
, digeneans and cestodes parasites was undertaken to establish research methodologies with fish parasites.
Myxosporean hyperparasites of gill monogeneans
are basal to the Multivalvulida.
Mounting of monogeneans
carried out under binocular magnifying glass; the determination of the various species was further done using the optical microscope.
Of the 941 parasites collected, Sciadicleithrumphithimum monogeneans
found were parasitizing the gills and the Capillaria sp.
For the study of monogeneans
and copepods, the gills were isolated whole and placed in water at 560C with vigorous agitation for one minute.
2010), 19 species of monogeneans
, nine digeneans and one species of acanthocephalan, together with 16 various larval forms have been found infecting this catfish; although the number of named species will undoubtedly grow in the future (Chibwana et al.
in introduced and native cichlids in Mexico: evidence of transfer.
New methods for collection and preservation of spirorchiid trematodes and polystomatid monogeneans
osteomystax reached where today is the Rosana's reservoir, the monogeneans
, that are specific, may had been lost because of the impacts and the new environmental conditions.
The objectives are: (1) identify the ectoparasites and endoparasites found among fish sample according to organ and water source/station; (2) determine the incidence rate of infection with Protozoans, Nematodes,Cestodes,Crustaceans, Acanthocephalans, Monogeneans
, and Digeneans according to the organs and source of tilapia; and (3) make morphological descriptions of the different parasites collected and identified from the fish samples.
