| molecular identification of heterakis spumosa obtained from brown rats (rattus norvegicus) in japan and its infectivity in experimental mice. | heterakis spumosa is a nematode of invasive rodents, mainly affiliated with rattus spp. of asian origin. despite the ecological importance and cosmopolitan distribution, little information is available on the genetic characteristics and infectivity to experimental animals of this roundworm. heterakis isolates obtained from naturally infected brown rats caught in 2007 in the city of sagamihara, east central honshu, japan, and maintained by laboratory passages were subjected to mitochondrial seque ... | 2014 | 24997621 |
| survival of ascaris suum and ascaridia galli eggs in liquid manure at different ammonia concentrations and temperatures. | eggs of ascaris suum from pigs are highly resistant and commonly used as a conservative indicator of pathogen inactivation during slurry storage. eggs of ascaridia galli, the poultry ascarid, are also known to be highly resistant but the suitability as an indicator of pathogen inactivation has never been tested. pig slurry has to be stored for several months to inactivate pathogens but chemical treatment of slurry may reduce this time. the suitability of a. galli as an indicator of slurry sanita ... | 2014 | 24893691 |
| response to ascaridia galli infection in growing chickens in relation to their body weight. | it was hypothesized that chickens with extremely varying body weights (bw) from an otherwise homogeneous host sample cope differently with ascaridia galli (schrank 1788) infection. small and large birds, falling into either the lower or the upper 5% quantiles of bw distribution of a parent stock flock, were selected at an age of 4 weeks, housed separately and fed restrictively with the same amount of feed. at week 5, all the small and large birds (635 and 1,297 g/bird, respectively; p < 0.001) w ... | 2014 | 24585156 |
