| [the effect of glucocorticoids on the diluting capacity of the kidney of a desert rodent: gerbillus campestris]. | the ability to excrete a water load was studied in wistar rats and in gerbils (gerbillus campestris). the rat excreted the entire water load in less than 2 h whereas gerbillus campestris excreted less than 60% of the water load in 4 h. the gerbils which had received a dose of 15 micrograms/100 g body weight dexamethasone improved their rate of excretion which attained 92 +/- 6% in 2 h 30 min. the antidiuretic hormone (adh) measured by radioimmunoassay at the time of maximum diuresis was undetect ... | 1991 | 1768308 |
| increase in cytochrome oxidase capacity of bat and other tissues in cold-acclimated gerbils. | to determine the effects of cold acclimation on the oxidative capacity of different tissues and their possible role in nonshivering thermogenesis (nst) in a desert rodent, the gerbil (gerbillus campestris), measurements of cytochrome oxidase activity (cox) were performed on homogenates of liver, brown adipose tissue (bat), and subsarcolemmal (ss) and intermyofibrillar (imf) fractions of skeletal muscle. total organ mass was also measured. gerbils were maintained either at thermoneutrality (tn) o ... | 1990 | 2159730 |
| adaptation to extreme ambient temperatures in cold-acclimated gerbils and mice. | to explain tolerance of heat and cold in gerbils (gerbillus campestris) in their natural environment, a comparative study was made of thermoregulatory reactions in these animals and white mice (mus musculus) of the same body mass exposed for 2-3 h to ambient temperatures (ta) ranging from -23 to 40 degrees c. metabolic rate (mr), evaporative heat loss (ehl), colonic temperature (tb), and electromyographic activity (emg) were measured. nonshivering thermogenesis (nst) was also evaluated from the ... | 1987 | 3605389 |
| substitution rate variation in closely related rodent species. | the existence of evolutionary rate variation has previously been demonstrated between different orders, different species and even between different regions of the same gene. to examine rate variation between closely related species of rodents we have sequenced the adenine phosphorybosyltransferase (aprt) gene from mus spicilegus, mus pahari, mastomys hildebrandtii, stochomys longicaudatus and gerbillus campestris and compared these sequences with the previously published mus musculus, rattus no ... | 1997 | 9023989 |
| safety evaluation of the sag2 rabies virus mutant in tunisian dogs and several non-target species. | the safety of the sag2 rabies virus, a highly attenuated mutant of the sad strain intended to vaccinate dogs by the oral route, was evaluated in local tunisian dogs and in five other local species likely to consume vaccine baits. these species were the domestic cat (felis catus), the jackal (canis aureus), the jerboa (jaculus orientalis), the merion (meriones sp.) and the gerbil (gerbillus campestris). the vaccine was administered orally to 21 dogs, 11 cats and eight jackals and orally or intram ... | 1999 | 10478416 |
| [action of cortisone and pilocarpine on the development of the salivary virus in the field-mouse (apodemus sylvaticus), the gerbil (meriones shawi) and the jerboa (dipodillus campestris)]. | | 1964 | 14190402 |
| epidemiology of tick-borne borreliosis in morocco. | the presence in morocco of argasid ticks of the ornithodoros erraticus complex, the vector of tick-borne relapsing fever (tbrf) in north africa, has been known since 1919, but the disease is rarely diagnosed and few epidemiological data are available. | 2012 | 23029574 |
| molecular detection of leishmania infantum and leishmania tropica in rodent species from endemic cutaneous leishmaniasis areas in morocco. | leishmaniasis remains a major public health problem in african nations, including morocco, where little is known about the vertebrate reservoirs involved in the causal parasites' transmission cycles. the present study investigates the role of rodent species as potential reservoirs of leishmania spp. in central morocco, where both l. tropica and l. infantum have been reported. | 2017 | 28969710 |
| molecular phylogenetics of the genus gerbillus (rodentia, gerbillinae): implications for systematics, taxonomy and chromosomal evolution. | although gerbils forms an important component of the mammalian fauna of arid and semi-arid area, the taxonomic and phylogenetic relationship within the species of the genus gerbillus are still ambiguous. the present paper introduces findings based on the whole cytochrome b (1140 bp) mitochondrial genes of seven species (gerbillus campestris, g. latastei, g. nanus, g. tarabuli, g. gerbillus, g. simoni and g. nigeriae) six of which are present in tunisia. our results show that all the gerbillus sp ... | 2010 | 20412863 |
| synaptonemal complex study in some species of gerbillidae without heterochromatin interposition. | synaptonemal complexes were studied in gerbillus campestris, meriones libycus, m. shawi, m. crassus, and in two hybrids m. shawi x m. libycus (gerbillidae, rodentia). in both the pure species and hybrids, there was no pairing of x and y chromosomes, as was previously observed in psammomys obesus and other gerbillidae species with gonosome-autosome translocations. a pair of autosomes was also located in proximity to the sex chromosomes in pachytene and showed unusual meiotic behavior with no, inc ... | 1989 | 2612211 |
| great adaptability of brown adipose tissue mitochondria to extreme ambient temperatures in control and cold-acclimated gerbils as compared with mice. | 1. the gerbil (gerbillus campestris) is a desert rodent able to tolerate high (38 degrees c) and low (-20 degrees c) ambient temperatures, probably due to both its low resting metabolic rate in hot environment and its high peak metabolic rate in cold. 2. measurement of mitochondrial state iv respiration and cytochrome-oxidase activity (cox) were made in interscapular brown adipose tissue (ibat), liver and hind limb muscles of gerbils and mice of nearly equal body mass, acclimated for 4 weeks at ... | 1988 | 2840240 |
| [metabolic adaptations of the gerbil, gerbillus campestris, to a desert climate. comparison with white mice]. | metabolic rate of gerbils was lower than that of mice (35%). we tried to assess the part played by brown adipose tissue in this low level. mitochondrial respiration (state 4), protein content and cytochrome-oxidase activity of interscapular bat mitochondria were very low in gerbils compared to mice, whereas in liver and muscle these parameters were not significantly different. like in fasting animals, the low level of basal energy expenditure of gerbils may be ascribed to low activity of bat. | 1987 | 2842012 |
