| antibody prevalence of toxoplasmosis in arabian gazelles and oryx in saudi arabia. | we determined the antibody prevalence of toxoplasmosis (toxoplasma gondii infections) in antelopes in saudi arabia. serum samples from 324 gazella subgutturosa marica, 202 gazella gazella, 70 gazella dorcas, and 12 arabian oryx (oryx leucoryx) were tested by the indirect hemagglutination test. antibodies to t. gondii were detected in 13(4.0%) g. subgutturosa marica, 12(5.9%) g. gazella, 3(4.3%) g. dorcas, and in none of the arabian oryx sampled. more adult gazelles were seropositive than juvenil ... | 1994 | 7760490 |
| sarcocystis infections in gazelles at the king khalid wildlife research centre, saudi arabia. | the prevalence of sarcocystis species in muscle samples from gazelles kept as breeding groups at the king khalid wildlife research centre, saudi arabia, was determined by fibreoptic examination, pepsin digestion and histological techniques. no macroscopic sarcocysts were detected by fibreoptic examination, and the overall prevalence of sarcocystis was 66 x 7 per cent by pepsin digestion, and 39 x 9 per cent by histological examination. by digestion, the tongue contained the highest density of br ... | 2000 | 10731071 |
| comparative analysis of reproductive cycles in female persian gazelle (gazella subgutturosa subgutturosa) (central asia) and sand gazelle (gazella subgutturosa marica) (arabian peninsula). | this study was conducted at the bukhara breeding centre (ouzbekistan, central asia) on persian gazelles (gazella subgutturosa subgutturosa) and at thumammah (saudi arabia) on sand gazelles (gazella subgutturosa marica). plasma prolactin (prl) and progesterone were determined in groups of females. because these females were under two different photoperiods (20 degrees n in saudi arabia and 40 degrees n in uzbekistan), some persian females were treated with melatonin implants. both groups of femal ... | 2001 | 11161770 |
| the efficacy of ivermectin and levamisole against natural nematodirus spathiger infection in the arabian sand gazelle (gazella subgutturosa marica) and the arabian mountain gazelle (gazella gazella) in saudi arabia. | the efficacy of two broad spectrum anthelmintics (ivermectin and levamisole) against the nematode nematodirus spathiger in the reem (arabian sand gazelle) and idmi (arabian mountain gazelle) at king khalid wildlife research centre (kkwrc) was determined. gazelles of both species naturally infected with n. spathiger were each divided into 3 groups. one group was treated with ivermectin, the other group with levamisole and the last group was left as untreated control. faecal egg counts were employ ... | 2007 | 17951010 |
| coagulation profile and platelet parameters of the arabian sand gazelle (gazella subgutturosa marica): comparison with humans and camels. | during march 2009, we evaluated the hemostatic profile and platelet indices of 18 arabian sand gazelles (gazella subgutturosa marica) and compared the results with those from humans and camels (camelus dromedarius). gazelles and camels had shorter activated partial thromboplastin times, lower proconvertin and higher antihemophilic factor coagulation activity, and plasma fibrinogen levels than humans. prothrombin time was longer in sand gazelles and shorter in camels than it was in humans. plasma ... | 2010 | 20966267 |
| data on phylogenetic analyses of gazelles (genus gazella) based on mitochondrial and nuclear intron markers. | the data provided is related to the article "phylogenetic analyses of gazelles reveal repeated transitions of key ecological traits and provide novel insights into the origin of the genus gazella" [1]. the data is based on 48 tissue samples of all nine extant species of the genus gazella, namely gazella gazella, gazella arabica, gazella bennettii, gazella cuvieri, gazella dorcas, gazella leptoceros, gazella marica, gazella spekei, and gazella subgutturosa and four related taxa (saiga tatarica, a ... | 2016 | 27054158 |
| fatal transmission of contagious caprine pleuropneumonia to an arabian oryx (oryx leucoryx). | contagious caprine pleuropneumonia (ccpp) is an infectious respiratory disease mainly affecting domestic goats. as ccpp has never been documented in grazing antelopes (subfamily hippotraginae), they were not considered susceptible. mycoplasma capricolum subspecies capripneumoniae (mccp) was isolated from pleural liquid collected during the necropsy of a severely emaciated arabian oryx with mild nasal discharge. the mccp isolate was then genotyped using a multilocus sequence scheme; the sequence ... | 2014 | 25069622 |
| macroscopic digestive tract anatomy of two small antelopes, the blackbuck (antilope cervicapra) and the arabian sand gazelle (gazella subgutturosa marica). | the digestive tract anatomy of 14 blackbucks (antilope cervicapra) and seven arabian sand gazelles (gazella subgutturosa marica) was quantified by dimensions, area and weight. data from the two small-sized antilopinae were evaluated against a larger comparative data set from other ruminants classified as having either a 'cattle-type' or 'moose-type' digestive system. the digestive anatomy of the blackbuck resembled that of 'cattle-type' ruminants, which corresponds to their feeding ecology and p ... | 2016 | 26514913 |
| retrospective evaluation of histopathologic findings in captive gazelle species. | capturing disease trends among different species has indisputable value to both veterinary clinicians and zoo managers for improving the welfare and management of zoo species. the causes of mortality for eight species of gazelle (addra gazelle, nanger dama; dorcas gazelle, gazella dorcas; grant's gazelle, nanger granti; sand gazelle, gazella leptoceros; saudi goitered gazelle, gazella subgutturosa; soemmerring's gazelle, nanger soemmerringii; thomson's gazelle, eudorcas thomsonii; and speke's ga ... | 2016 | 27010271 |
| digesta kinetics in gazelles in comparison to other ruminants: evidence for taxon-specific rumen fluid throughput to adjust digesta washing to the natural diet. | digesta flow plays an important role in ruminant digestive physiology. we measured the mean retention time (mrt) of a solute and a particle marker in the gastrointestinal tract (git) and the reticulorumen (rr) of five gazelles and one dikdik species. species-specific differences were independent from body mass (bm) or food intake. comparative evaluations (including up to 31 other ruminant species) indicate that mrt git relate positively to bm, and are less related to feeding type (the percentage ... | 2015 | 25637787 |
| does size matter? comparison of body temperature and activity of free-living arabian oryx (oryx leucoryx) and the smaller arabian sand gazelle (gazella subgutturosa marica) in the saudi desert. | heterothermy, a variability in body temperature beyond the normal limits of homeothermy, is widely viewed as a key adaptation of arid-adapted ungulates. however, desert ungulates with a small body mass, i.e. a relatively large surface area-to-volume ratio and a small thermal inertia, are theoretically less likely to employ adaptive heterothermy than are larger ungulates. we measured body temperature and activity patterns, using implanted data loggers, in free-ranging arabian oryx (oryx leucoryx, ... | 2012 | 22001971 |
| comparison of the effects of racemic ketamine and s-ketamine for anesthesia in rheem gazelles (gazella subgutturosa marica) and subgutturosa gazelles (gazella subgutturosa subgutturosa). | to evaluate effects of racemic ketamine and s-ketamine in gazelles. | 2011 | 21879973 |
| physiological adjustments of sand gazelles (gazella subgutturosa) to a boom-or-bust economy: standard fasting metabolic rate, total evaporative water loss, and changes in the sizes of organs during food and water restriction. | to test the hypothesis that desert ungulates adjust their physiology in response to long-term food and water restriction, we established three groups of sand gazelles (gazella subgutturosa): one that was provided food and water (n = 6; ctrl) ad lib. for 4 mo, one that received ad lib. food and water for the same period but was deprived of food and water for the last 4.5 d (n = 6; expt(1)), and one that was exposed to 4 mo of progressive food and water restriction, an experimental regime designed ... | 2006 | 16826507 |
| heterothermy of free-living arabian sand gazelles (gazella subgutturosa marica) in a desert environment. | to test whether free-living desert ungulates employ heterothermy to reduce water loss, we measured core body temperature (t(b)) of six free-living arabian sand gazelles (gazella subgutturosa marica), a small desert antelope (12-20 kg) that lives in the deserts of saudi arabia, where air temperature (t(a)) often exceeds 40 degrees c. we found that the mean daily t(b) varied by 2.6+/-0.8 degrees c during summer (june-july) and 1.7+/-0.3 degrees c during winter (january-february); over both seasons ... | 2006 | 16574802 |
| experimental infection of arabian sand gazelles, gazella subgutturosa marica with eimeria rheemi. | three young arabian sand gazelles (gazella subgutturosa marica) were each infected with 20,000 sporulated oocysts of eimeria rheemi collected from a naturally infected rheem gazelle. both prepatent and patent periods were 7 days and the infected animals consistently passed large numbers of oocysts in their feces during patency. infection with e. rheemi at this dose was associated with clinical coccidiosis in the form of 2 days of diarrhea before patency, continuing to day 15 postinoculation. the ... | 1996 | 8604118 |
| serum chemistry values for arabian sand gazelles (gazella subgutturosa marica). | values for urea, creatinine, glucose, total bilirubin, sodium, potassium, chloride, calcium, phosphates, magnesium, alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, lactate deshydrogenase, and creatine-kinase are reported for the first time for 32 sand gazelles (gazella subgutturosa marica) in saudi arabia. comparisons were made between two groups: one sampled before a trip and the other sampled after a 14 hr trip. only aspartate aminotransferase was higher in the seco ... | 1994 | 7933288 |
| chromosomal polymorphism in sand gazelles (gazella subgutturosa marica). | a total of 84 gazella subgutturosa from three captive populations (two in saudi arabia, one in qatar) were karyotyped. the number of chromosomes is 33, 32, or 31 for the males and 32, 31, or 30 for the females because of the x-autosome translocation that is common in the genus and a centric fusion between the two pairs of acrocentric chromosomes. the g- and r-banded karyotypes of gazelles translocated show that this fusion is the same as that previously reported for gazelles from jordan. the pre ... | 2004 | 8270771 |
