| pesticide contamination of water rats in the murrumbidgee irrigation areas, new south wales, australia, 1970-72. | organochlorine pesticides were found in all samples of livers, kidneys, mammary glands, and fetuses of eastern water rats (hydromys chrysogaster) collected in the murrumbidgee irrigation areas of new south wales in 1970 and 1972. dde was the predominant residue. livers contained 0.01--3.10 ppm sigma ddt air-dried weight; kidneys, less than 0.01--1.12 ppm; mammary glands, 0.14--23.75 ppm; fetal liver, 0.28--0.66 ppm. variations in residue levels are discussed in relation to the possible effects o ... | 1979 | 461114 |
| experimental infections of brush-tailed possums, common wombats and water rats with leptospira interrogans serovars balcanica and hardjo. | of 12 brush-tailed possums (trichosurus vulpecula) inoculated with leptospira interrogans serovar balcanica 11 developed migroagglutination (ma) antibody to jardjo antigen by 14 days postincubation (pi). leptospiruria was observed in 2 possums 117 to 145 days pi. of 6 possums inoculated with serovar hardjo 4 developed low short-lived titres by day 18 pi. two of 3 wombats (vombatus ursinus) inoculated with balcanica had high ma titres (greater than or equal to 1:128) by day 16 pi and leptospiruri ... | 1979 | 533478 |

| the prevalence of anti-leptospiral agglutinins in sera of wildlife in southeastern australia. | anti-leptospiral agglutinins were found in the serum from 18 (7 species) of 419 (25 species) animals sampled from various areas of southeastern australia. positive serologic reactions were observed in 5 of 25 (20%) brush-tailed possum (trichosurus vulpecula), 1 of 26 (3.8%) tammar wallaby (macropus eugenii), 2 of 12 (16.7%) swamp wallaby (wallabia bicolor), 1 of 3 (33.3%) koala (phascolarctos cinereus), 3 of 41 (7.3%) common wombat (vombatus ursinus), 2 of 100 (2%) bush rat (rattus fuscipes) and ... | 1981 | 7241704 |
| protozoan parasites and pathological findings in hydromys chrysogaster (muridae: hydromyinae) from queensland. | tissues from 23 australian water rats (hydromys chrysogaster) collected from five localities in central and northern queensland, australia, between february 1992 and may 1993, were examined for protozoan parasites and additional pathological changes. we found klossiella hydromyos in the kidneys, toxoplasma gondii in the brain and skeletal muscles and sarcocystis sp. in the somatic musculature. other pathological findings, including interstitial nephritis, interstitial pneumonia and a tongue absc ... | 1996 | 8722276 |
| the fluorescent dye 3, 3' dihexyloxacarbocyanine iodide selectively stains the midpiece and apical region of the heads of murid rodent spermatozoa. | fluorescence microscopy of caudal epididymal spermatozoa stained with 3, 3' dihexyloxacarbocyanine iodide (dioc6(3)) showed intense fluorescence along the concave surface of the apical hook of spermatozoa of rattus species and along the upper concave margin of the sperm head in mus musculus. in the spermatozoa of hydromys chrysogaster, melomys cervinipes, and pseudomys australis, the two ventral processes also fluoresced brightly. in p. australis, fluorescence in the apical hook of sperm heads w ... | 1995 | 9044657 |
| australian helminths in australian rodents: an issue of biodiversity. | the australian public as well as australian funding bodies are generally unsympathetic to native murids, rats and mice, in spite of the fact that 36% have either become extinct or critically endangered since european settlement. the endemic australian parasites of these rats and mice have been even less sympathetically regarded. prior to 1958 very little work was carried out on the helminths of australian rodents and little more is known today. records are known from only 28% of the extant host ... | 1998 | 9673864 |
| energetics of locomotion by the australian water rat (hydromys chrysogaster): a comparison of swimming and running in a semi-aquatic mammal. | semi-aquatic mammals occupy a precarious evolutionary position, having to function in both aquatic and terrestrial environments without specializing in locomotor performance in either environment. to examine possible energetic constraints on semi-aquatic mammals, we compared rates of oxygen consumption for the australian water rat (hydromys chrysogaster) using different locomotor behaviors: swimming and running. aquatic locomotion was investigated as animals swam in a water flume at several spee ... | 1999 | 9914144 |
| structure and innervation of the vibrissal follicle-sinus complex in the australian water rat, hydromys chrysogaster. | light and electron microscopic techniques were used to examine the structure and innervation of the mystacial vibrissal follicle-sinus complex (f-sc) in the australian water rat. the f-scs of this semiaquatic rodent show the same morphologic elements described in terrestrial rats but differ in size, structure, and innervation. most striking is the size of the water rat's caudal f-scs, measuring 6.3 mm in length and 2.4 mm in diameter. the sinus system is divisible into a ring sinus and a caverno ... | 1999 | 10421867 |
| lung morphology in rodents (mammalia, rodentia) and its implications for systematics. | a new nomenclature of the lung lobes and of the bronchial tree is presented, with which the lungs in 40 species of 11 rodent families are described. whole, fixed lungs and silicone casts of the bronchial tree are tested for 23 characters, based on the distribution of lung lobes, the number and geometry of first order bronchi, the pulmonary blood supply, and lung symmetry. ten lung morphotypes are recognized, seven of them representing one or more families: castor type (castoridae), cryptomys typ ... | 2000 | 11077434 |
| cdna nucleotide sequence encoding the zpc protein of australian hydromyine rodents: a novel sequence of the putative sperm-combining site within the family muridae. | this comparative study of the cdna sequence of the zona pellucida c (zpc) glycoprotein in murid rodents focuses on the nucleotide and amino acid sequence of the putative sperm-combining site. we ask the question: has divergence evolved in the nucleotide sequence of zpc in the murid rodents of australia? using rt-pcr and (race) pcr, the complete cdna coding region of zpc in the australian hydromyine rodents notomys alexis and pseudomys australis, and a partial cdna sequence from a third hydromyin ... | 2002 | 12463524 |

| outbreak with clonally related isolates of corynebacterium ulcerans in a group of water rats. | the zoonotic bacterium corynebacterium ulcerans may be pathogenic both in humans and animals: toxigenic strains can cause diphtheria or diphtheria-like disease in humans via diphtheria toxin, while strains producing the dermonecrotic exotoxin phospholipase d may lead to caseous lymphadenitis primarily in wild animals. diphtheria toxin-positive corynebacterium ulcerans strains have been isolated mainly from cattle, dogs and cats. | 2015 | 25887321 |
| trypanosomes of australian mammals: a review. | approximately 306 species of terrestrial and arboreal mammals are known to have inhabited the mainland and coastal islands of australia at the time of european settlement in 1788. the exotic trypanosoma lewisi was the first mammalian trypanosome identified in australia in 1888, while the first native species, trypanosoma pteropi, was taxonomically described in 1913. since these discoveries, about 22% of the indigenous mammalian fauna have been examined during the surveillance of trypanosome biod ... | 2014 | 25161902 |
| masticatory muscle architecture in a water-rat from australasia (murinae, hydromys) and its implication for the evolution of carnivory in rodents. | murines are well known for their generalist diet, but several of them display specializations towards a carnivorous diet such as the amphibious indo-pacific water-rats. despite the fact that carnivory evolved repeatedly in this group, few studies have investigated associated changes in jaw muscle anatomy and biomechanics. here, we describe the jaw muscles and cranial anatomy of a carnivorous water-rat, hydromys chrysogaster. the architecture of the jaw musculature of six specimens captured both ... | 2017 | 28585258 |
| hydrodynamic reception in the australian water rat, hydromys chrysogaster. | the australian water rat, hydromys chrysogaster, preys on a wide variety of aquatic and semiaquatic arthropods and vertebrates, including fish. a frequently observed predatory strategy of hydromys is sitting in wait at the water's edge with parts of its vibrissae submersed. here we show that hydromys can detect water motions with its whiskers. behavioural thresholds range from 1.0 to 9.4 mm s-1 water velocity, based on maximal horizontal water velocity in the area covered by the whiskers. this h ... | 2020 | 32306057 |
