| output of gastrointestinal nematode eggs in the feces of captive gazelles (gazella dama mhorr, gazella cuvieri and gazella dorcas neglecta) in a semiarid region of southeastern spain. | feces from 62 captive african gazelles, including mhorr gazelles (gazella dama mhorr), cuvier's gazelles (gazella cuvieri), and dorcas gazelles (gazella dorcas neglecta), were examined over the course of a year to quantitate nematode egg excretion patterns. strongyloides sp. eggs appeared only in g. dama during the rainy season. trichostrongylidae egg excretion showed a marked seasonal variation, with very low levels during the dry and hot period, a finding that is probably attributable to hypob ... | 2006 | 17319122 |
| copro-antigen capture elisa for the detection of teladorsagia (ostertagia) circumcincta in sheep: improvement of specificity by heat treatment. | a copro-antigen capture elisa for the detection of teladorsagia circumcincta infection in sheep was developed and evaluated. experiments with faeces from worm-free sheep, that had been spiked with known concentrations of excretory-secretory (e-s) antigen indicated that a positive signal was generated with 180 ng of e-s/ml. a nested design, based on 8 infected and 8 worm-free sheep, was employed to assess the stages during sample preparation contributing to variation in signal from the assay. thi ... | 2004 | 15267118 |
| dose determination studies for monepantel, an amino-acetonitrile derivative, against fourth stage gastro-intestinal nematode larvae infecting sheep. | monepantel is the first compound from the recently discovered amino-acetonitrile derivative (aad) class of anthelmintics to be developed for use in sheep. three dose determination studies were conducted in australia and switzerland to identify the minimum therapeutic dose of monepantel when formulated for the oral treatment of sheep to control fourth stage (l4) gastro-intestinal nematode larvae. in each study, sheep infected with the target nematodes (selected from haemonchus contortus, teladors ... | 2008 | 18760536 |
