| seroprevalence of toxoplasma gondii in llamas (lama glama) in the northwest usa. | serum samples from 283 llamas (lama glama) from oregon, washington state and idaho were tested for antibodies to toxoplasma gondii using the modified agglutination test. antibodies were found in 95 (33.5%) llamas. percent seropositivity in serum dilutions of 1:25, 1:50, 1:500, and 1:5000 was 9.5%, 18.3%, 4.9%, and 0.7%, respectively. | 1992 | 1466137 |
| redescription of trichuris tenuis chandler, 1930, from llamas (lama glama) in oregon with a key to the species of trichuris present in north american ruminants. | whipworms collected from llamas (lama glama) in oregon were identified as trichuris tenuis chandler, 1930. a redescription, based on the specimens collected from llamas and examination of the paratypes, is presented. the unique form of the cloaca in t. tenuis separates males of this species from all other species of trichuris known to occur in ruminants. among species of trichuris for which adequate descriptions of the female exist, t. tenuis can be distinguished using an array of characters inc ... | 1991 | 1992097 |
| identification of lamanema chavezi becklund 1963 infection in a llama (lama glama) in the united states. | infection with lamanema chavezi, a parasitic nematode of new world camelids, was diagnosed by examination of feces and formalin-fixed liver from a 14-month-old female llama (lama glama) that died after a 6-week illness. infection with l. chavezi was initially suspected when a granuloma containing an unidentified nematode was detected microscopically in the hepatic parenchyma from a necropsy specimen. the subsequent diagnosis of l. chavezi infection was based on the morphologic features of 2 imma ... | 2014 | 24398908 |
| prevalence of neoplasia in llamas and alpacas (oregon state university, 2001-2006). | prevalence and type of neoplastic disease were determined in 551 camelid submissions (368 alpacas [lama pacos], 180 llamas [lama glama], and 3 cases in which species was not identified) over a 5-year period. forty neoplasms were identified in 38 animals (6.9%). prevalence of neoplasia in llamas was higher (11%) than in alpacas (4.9%). mean age of camelids with neoplasia was 9.42 +/- 4.9 years. mean age of alpacas with neoplasia (5.48 +/- 3.7 years) was significantly less than of llamas with neop ... | 2007 | 17402619 |
| development and application of a dot-elisa test for the detection of serum antibodies to fasciola hepatica antigens in llamas. | a microenzyme-linked immunosorbent assay (dot-elisa) was developed to detect serum antibodies against fasciola hepatica antigens in llamas. sera from five f. hepatica-infected and 11 non-infected llamas were used in initial test development. nitrocellulose filter disks containing f. hepatica excretory-secretory product were placed in 96-well microtiter plates, washed, blocked with tween-20, then incubated with four-fold serial dilutions of llama sera. after incubation with rabbit anti-llama igg ... | 1995 | 7676604 |
| fecal survey of llamas (lama glama) in oregon: incidental recovery of nematodirus battus. | between september 1985 and march 1987, 243 fecal specimens from llamas (195 adults, 48 crias) were examined for parasite eggs. of the adults, 78% had at least one type of egg. trichostrongyles were found in 67% of the adults, nematodirus spp in 23%, strongyloides spp in 9%, capillaria spp in 8%, and trichuris spp in 5%. of the crias, 90% had at least one kind of egg. trichostrongyles were found in 71% of the crias, nematodirus spp in 52%, strongyloides spp in 17%, and trichuris spp and capillari ... | 1987 | 3693012 |
| prevalence of eimeria spp. (apicomplexa: eimeriidae) in oregon llamas. | eimeria alpacae, e. punoensis, e. lamae, and e. macusaniensis were identified in fecal samples from 189 llama (lama glama (l.] adults and 50 llama crias (animals less than one year of age of any species in the genus lama) from central and western oregon. in both adults and crias, e. alpacae was the most common species found. the least common was e. macusaniensis, which was found in only two adults. overall prevalence and numbers of animals with mixed infections was approximately twice as high in ... | 1988 | 3183993 |
