coccidia of the llama, lama glama, in colorado and wyoming.fecal samples were collected from 144 llamas, lama glama, on four premises in northern colorado and southern wyoming. feces were examined for the presence of coccidial oocysts; eimeria alpacae was found in 55.6%, eimeria lamae in 67.3% and eimeria macusaniensis in 1.4% of the samples. an adult female llama was found to be infected with eimeria macusaniensis at necropsy. this is the first report of these species of coccidia in the llama.19911763488

prevalence of eimeria macusaniensis (apicomplexa: eimeriidae) in midwestern lama spp.to compare the prevalence of eimeria macusaniensis among midwestern llamas (lama glama), alpacas (lama pacos), and guanacos (lama guanicoe), feces were obtained from lama spp. in 10 states between october 1989 and february 1996. feces were examined by centrifugal flotation in sugar solution (specific gravity--1.28-1.30), and oocysts were quantified by a modified mcmaster method. data were compared by host species and age classifications. typical oocysts occurred in samples from 28% of 76 herds a ...199910219324

prevalence and significance of gastrointestinal helminths and protozoa in south american camelids in switzerland.a cross sectional study was conducted to determine the prevalence and significance of endoparasitic infections in south american camelids (sac) in switzerland. qualitative and quantitative coproscopic examinations were performed in 38 farms during the grazing period. management practices with possible interference with parasitic infections were analyzed. on the farm level prevalences of endoparasitic infections were: trichostrongyles 87%; trichuris sp. 74%; capillaria sp. 68%; nematodirus battus ...200617009711
eimeria macusaniensis infection in 15 llamas and 34 alpacas.15 llamas and 34 alpacas between 3 weeks and 18 years old with fecal oocysts or intestinal coccidial stages morphologically consistent with eimeria macusaniensis were examined. nineteen of the camelids were admitted dead, and 30 were admitted alive. camelids admitted alive accounted for 5.5% of all camelid admissions during this period.200717199499
diagnosis and treatment of eimeria macusaniensis in an adult alpaca with signs of colic.a young adult pregnant alpaca was presented with an acute episode of abdominal pain. hematology revealed mild anemia, neutropenia with a degenerative left shift and moderate toxic changes in neutrophils, hyperfibrinogenemia, hypoproteinemia, and hypoalbuminemia. abdominal ultrasound showed a small intestinal segment with severely increased wall thickness and collapsed lumen. exploratory laparotomy revealed a markedly thickened 60cm jejunal segment with reddened serosa from which a full-thickness ...200918036857
comparison of methods to detect gastrointestinal parasites in llamas and alpacas.to compare relative sensitivity and overall yields of various methods of fecal examination for gastrointestinal parasites in llamas and alpacas.200818312182
infection of llamas with stored eimeria macusaniensis oocysts obtained from guanaco and alpaca feces.oocysts obtained from a guanaco and an alpaca with natural infections were identified as eimeria macusaniensis and evaluated for host specificity and infectivity over time. in 3 separate trials conducted over 4 yr, 4 adult llamas were fed 500-5,000 sporulated oocysts obtained from guanaco feces stored under laboratory conditions for 41-84 mo. infections with prepatent periods of 36-41 days and patent periods of 38-55 days developed in 4/4 llamas. in a fourth trial, 3 adult llamas and 1 alpaca we ...200818576765
prevalence of eimeria macusaniensis and eimeria ivitaensis in south american camelids of northwest argentina.faecal samples from mostly adult llamas (n=626), vicuñas (n=161) and guanacos (n=4) were obtained between december 2004 and july 2008 in three provinces of northwest argentina in order to study the prevalence of eimeria macusaniensis and eimeria ivitaensis. faeces were examined by a flotation technique using a cl(2)zn+clna solution (specific gravity=1.59). oocysts of e. macusaniensis occurred in 88.3% of 77 llama herds and in 50.3% of 626 llamas sampled whereas oocysts of e. ivitaensis occurred ...200919349120
eimeria macusaniensis associated lesions in neonate alpacas dying from enterotoxemia.histopathological analysis of 108 intestine samples (103 grossly affected ileum and 5 jejunum) taken from clostridium-induced neonatal alpaca (vicugna pacos) enterotoxemia mortalities collected in the departments of arequipa, puno and cusco of southern peru during the 2005-2008 birth seasons (january-march), revealed the presence of large numbers of both asexual and sexual stages of eimeria macusaniensis in 33/108 (30.55%) of the samples with moderate to severe necrotized and/or hemorrhagic ente ...201019926224
zoonotic parasites associated with felines from the patagonian holocene.feline coprolites were examined for parasites with the aim of studying ancient infections that occurred in the patagonian region during the holocene period. eggs compatible to trichuris sp., calodium sp., eucoleus sp., nematodirus sp., oesophagostomum sp. (nematoda), monoecocestus sp. (cestoda) and eimeria macusaniensis (coccidia) were recovered from faecal samples. the results obtained from the analysis provide evidence of consumption by felids of the viscera of both rodents and camelids. this ...200920140380
first paleoparasitological results from late holocene in patagonian coprolites.these are the first paleoparasitological results from the late holocene in patagonian coprolites. coprolites collected from layers dated at 3,480 and 2,740 yr before present (b.p.), from the archaeological site cerro casa de piedra, were examined. the site is a hill located in a forest steppe ecotone in perito moreno national park. the coprolites could belong to humans or to other carnivores such as canids. after rehydration and spontaneous sedimentation of the samples, the parasite contents wer ...201020557211
development of a nested polymerase chain reaction assay for the detection of eimeria macusaniensis in camel id feces.objective-to test the ability of a nested pcr assay to detect eimeria macusaniensis at various stages of infection in alpacas. animals-4 healthy adult alpacas with no detectable e macusaniensis. procedures-alpacas were inoculated with 2 × 10(4) sporulated oocysts. serial fecal samples collected during the next 38 days were tested via sucrose flotation and pcr assay. results-oocyst passage was detected via fecal flotation in all 4 alpacas 31 to 35 days after inoculation. three had positive ...201222204283

parasitic diversity found in coprolites of camelids during the holocene.knowledge of parasitic infections to which fauna was exposed in the past provides information on the geographical origin of some parasites, on the possible dispersal routes and for archaeological fauna on the potential zoonotic risk that human and animal populations could be exposed. the aim of the present study was to examine the gastrointestinal parasite present in camelid coprolites collected from the archaeological site cerro casa de piedra, cave 7 (ccp7), patagonia, argentina. coprolites we ...201525859925
new parasitological findings for pre-hispanic camelids.paleoparasitological examination provides information of parasite-host associations in the past, shedding light on the geographical origin of some parasites, on the possible dispersal routes and on some of the processes that modelled the parasitic communities. the aim of the present study was to examine parasite remains present in camelid coprolites collected from the archaeological site alero destacamento guardaparque, patagonia and to discuss the paleoparasitological findings in a biogeographi ...201728679457
new paleoparasitological investigations from the pre-inca to hispanic contact period in northern chile.paleoparasitological studies have demonstrated that changes in environment or culture are reflected in the patterns of parasitic infection diseases in populations worldwide. the advent of agriculture and animal domestication, with its accompanying reduction in human mobility and expanding population involves changes in or emergence of, parasites, the so-called first epidemiological transition. cultural processes related to territory occupation contribute to both loss and acquisition of parasites ...201829191518
