A total of 319 fleas belonging to 5 species in 5 genera were collected inside and outside the houses, an average of 44 per house (maximum 71): Pulex
irritans, Echidnophaga gallinacea, and Ctenocephalides canis fleas were collected inside the houses (244, 76.
After sequencing the entire genomes of 11 sexual and asexual genotypes of Daphnia pulex
, a model organism for the study of reproduction that is more commonly known as the water flea, the team discovered that every asexual genotype shared common combinations of alleles for two different chromosomes transmitted by asexual males without recombination.

STEED, MEGAN L.
A flea Pulex
irritans commonly serves as an intermediate host for D.
D) Sequence alignment of the PTX/RDX binding site for several species: Danio rerio, Tetraodon nigroviridis, Homo sapiens, Pan troglodytes, Rattus norvegicus, Mus musculus, Gallus gallus, Xenopus tropicalis, Anolis carolinensis, Anopheles gambiae, Daphnia pulex
, and Caenorhabditis elegans.
Opossums were also parasitized by the flea Pulex
simulans and the tiny fur mite Didelphilichus serrifer; the latter species represents a new state record for Nebraska.
Washington, Feb 09 (ANI): Scientists have discovered that the near-microscopic freshwater crustacean Daphnia pulex
, or water flea is the animal with the most genes, about 31,000.
Lactose causes heart arrhythmia in the water flea Daphnia pulex
An ecological relationship between Aphanizomenon and Daphnia pulex
In Gilbert (1990), this is seen as the strain of Daphnia pulex
that had coexisted with toxic Anabaena affinis had evolved resistance to toxin (Gilbert 1990).
