| isolation of giardia from a llama and from sheep. | giardia cysts were detected in feces of a domestic llama (lama glama) and in feces of lambs (ovis aries) from wisconsin, u.s.a. all of the animals examined were immature, and they had recent histories of poor condition and passing unformed or semiformed, pale stools. giardia cysts from both host species were excysted in vitro, and the trophozoites were cultivated axenically. furthermore, giardia cysts from both sources were shown to produce infection in mongolian gerbils (meriones unquiculatus). ... | 1987 | 3607656 |
| blood serum concentrations of selenium in female llamas (lama glama) in relationship to feeding practices, region of united states, reproductive stage, and health of offspring. | serum se and vitamin e concentrations were determined twice in each of 35 female llamas from a high-se region and 96 female llamas from a low-se region of the united states. the first determination was taken at a random time during gestation and the second shortly after parturition. at the time of postpartum sampling, a sample was also taken from the cria. dietary information was collected from each llama owner and a subjective estimate of strength and vigor was assigned by the owner to each cri ... | 1995 | 7601762 |
| genetic differentiation of mites of the genus chorioptes (acari: psoroptidae). | in an effort to clarify the species status of mites of the genus chorioptes the second internal transcribed spacer of the rrna gene was characterized in 14 isolates from cattle, horse, sheep and llama of different geographic origins. the genotypes segregated into two clearly separated groups of dna sequences. in addition, two phenotypes could be distinguished by the lengths of the outer opisthosomal setae of male adults which had previously been designated as chorioptes bovis and chorioptes texa ... | 1999 | 10399307 |
