Protozoal coinfection in horses with equine protozoal myeloencephalitis in the eastern United States
1. A method for estimating the proportions of bacterial- and protozoal-N in the total non-ammonia-N reaching the lower gut of the ruminant under steady-state conditions was evaluated. Three trials using two different diets were conducted with a Holstein steer equipped with a rumen cannula and duodenal re-entrant cannulas. 2. An intraruminal primed infusion of (15NH4)2SO4 was administered for 68...
Finch trichomonosis, caused by the protozoal parasite Trichomonas gallinae, was first recognized as an emerging infectious disease of British passerines in 2005. The first year of seasonal epidemic mortality occurred in 2006 with significant declines of greenfinch Carduelis chloris and chaffinch Fringilla coelebs populations. Here, we demonstrate that large-scale mortality, principally of green...
ferent among treatments. Protozoal counts were not different among treatments (P > 0.05) in ruminal or omasal samples. Generic protozoal counts were not different (P > 0.05) among treatments, corresponding with similar banding profiles from DGGE. Multivariate statistics showed no difference (P > 0.05) in generic distribution of protozoa in ruminal vs. omasal samples, supporting absence of selec...
