| attempted cross-transmission of coccidia between sheep and goats and description of eimeria ovinoidalis sp. n. | attempted infection of 2 young lambs with oocysts of eimeria christenseni from a goat was unsuccessful. negative results were obtained also when young kids were fed oocysts of eimeria ninakohlyakimovae from sheep. there was no difficulty in infecting lambs with the sheep coccidium resembling e. ninakohlyakimovae nor goats with the goat coccidium e. christenseni. oocysts from the goat measured 38.4 x 26.7 microns, but were easily distinguished from eimeria ahsata from the sheep by sporocyst size ... | 1979 | 480272 |
| epizootiology of eimeria ahsata coccidiosis in león (spain). | the epizootiology of ovine coccidiosis caused by eimeria ahsata was studied in four flocks in the province of león (spain), between january 1978 and december 1979. the intensity of infection was found to be 25.5 +/- 1.7% and was similar in winter and spring. eimeria ahsata was the most common species in 83.1% of the 1620 samples examined. it was also found in 86.2% of the animals examined. only 0.3% of the positive samples contained oocysts of a single species, and samples containing four specie ... | 1988 | 3369071 |
| eimeria ahsata honess from domestic sheep (ovis aries) in italy. | examination for coccidia of 20 domestic sheep (ovis aries) from a farm in rome province revealed the following 5 species: eimeria ahsata honess, e. intricata spiegl, e. ovina levine & ivens, e. ovinoidalis mcdougald, and e. parva kotlán, mócsy & vajda. of these species, only e. ahsata was not previously reported in italy. for this reason, a description of this coccidium and a statistical analysis of size differences between e. ahsata and e. ovina are given. | 1980 | 7400992 |
| ribosomal rna sequences for the specific detection of toxoplasma gondii by hybridization assay. | we describe the development of five oligonucleotide probes which target the small sub-unit rrna of toxoplasma gondii. these probes bind to different regions within the rrna and all were effective in producing a detectable signal with as little as 10 ng of total cellular rna. one probe in particular, tgb, was able to detect as little as 1 ng of rna and was the most specific. a sixth probe, previously developed for hybridization with sarcocystis spp., was evaluated for its specificity and was show ... | 1993 | 8321257 |
| sensitive and specific polymerase chain reaction detection of toxoplasma gondii for veterinary and medical diagnosis. | a polymerase chain reaction (pcr) method was developed for the detection of toxoplasma gondii. a universal- and a t. gondii-specific primer was used to amplify a region of the small subunit ribosomal rna gene. this approach allows for a theoretical detection limit of 0.01 zoite of t. gondii per sample assayed. experiments showed that this pcr method could detect 0.1 pg of t. gondii dna, which represents about one organism. polymerase chain reaction tests using dnas of cat, dog, swine, cattle, hu ... | 1993 | 8431804 |

| epidemiology of eimeria infections in an austrian milking sheep flock and control with diclazuril. | in a flock of milking sheep from styria (austria), the dynamics of eimeria oocyst excretion was monitored in the lambing season 2003-2004 and a treatment trial with 1 mg/kg diclazuril (single dose on day 0 of study) was conducted in two groups of early weaned lambs. adult animals (n = 30 ewes, 30 yearlings) excreted oocysts of different species (weekly prevalences from week -7 ante partum to week 5 post-partum: ewes 20-60%, yearlings 38-73%) in low intensities (< or = 6000 oocyst per gram of fae ... | 2005 | 15817196 |

| longitudinal prevalence, oocyst shedding and molecular characterisation of eimeria species in sheep across four states in australia. | the prevalence of eimeria in sheep in australia has not been well described, therefore a quantitative pcr (qpcr) was developed, validated and used to study the prevalence and oocyst concentration in lamb faecal samples at three sampling periods (weaning, post-weaning and pre-slaughter) from eight farms across south australia, new south wales, victoria and western australia. a total of 3412 faecal samples were collected from approximately 1182 lambs across the 4 states and screened for the presen ... | 2014 | 25033746 |
| genetic characterization and phylogenetic analysis of eimeria arloingi in iranian native kids. | among the 16 species of eimeria from goats, eimeria arloingi and eimeria ninakohlyakimovae are regarded as the most pathogenic species in the world and cause clinical caprine coccidiosis. e. arloingi is known to be an important cause of coccidiosis in iranian kids. molecular analyses of two portions of nuclear ribosomal dna (internal transcribed spacer1 (its1) and 18s rdna) were used for the genetic characterization of the e. arloingi. comparison of the sequencing data of e. arloingi obtained in ... | 2013 | 23779225 |
