Microbiome influence on host community dynamics: Conceptual integration of microbiome feedback with classical host–microbe theory

open access: yesEcology Letters, Volume 24, Issue 12, Page 2796-2811, December 2021., 2021
Microbiome influence on host ecology has been investigated using classical ecological theory which represent mechanistic interactions, but are difficult to evaluate empirically. Alternatively, host–microbiome feedback theory represents microbiome dynamics impacts on host fitness as simple net effects, but are easily amenable to experimental evaluation.

Diurnal variation in egg excretion by Heterakis gallinarum

open access: yesParasitology, 2018
AbstractPeriodicity in nematode egg excretion may be of evolutionary origin as it can favour dispersal of the eggs in the environment. We investigated whether egg excretion by Heterakis gallinarum shows a repeatable pattern of periodicity. The faecal egg concentration and total number of eggs excreted within 4-h intervals were significantly affected by

Transmission of histomoniasis with male Heterakis gallinarum (Nematoda)

open access: yesParasitology, 1969
Histomoniasis was transmitted to poults inoculated orally with recently harvested whole intact male worms in three trials (4/5, 5/6, 2/4), but not with female worms (0/5, 0/9, 0/3). When triturated male worms were given in two trials, the rate of transmission was reduced (3/5, 0/10).
