an ultrastructural study on gastric endocrine cells in the stomach gland patch of the koala phascolarctos cinereus.the endocrine cells in the stomach gland patch of the koala (phascolarctos cinereus) were studied ultrastructurally. they were classified into 3 types based on the ultrastructural profiles of their endocrine granules and tentatively categorized as type i, ii, and iii endocrine cells. type i cells contained round granules that were for the most part larger than those observed in the other 2 cell types. the granules ranged from moderate to relatively high in electron density. type ii cells were an ...19902220027
a survey of koala road kills in new south wales.between 1984 and 1990, 75 koalas (phascolarctos cinereus) from the central northern coast of new south wales (australia) were presented for necropsy due to motor vehicle accidents. the koalas consisted of 44 males and 31 females. fifty one of these were between 2 and 7 yr (39 males and 12 females). the greater proportion of koalas, especially males, were struck by vehicles between june and december. the main injuries detected were head injuries (44), hemoperitoneum (16), limb injuries (16), hemo ...19911758032
topography of the major superficial lymph nodes and their efferent lymph pathways in the koala (phascolarctos cinereus).the koala has an inguinoaxillary lymph trunk on either side of the ventral midline, and this carries efferent lymph from the superficial inguinal lymph node directly to the deep axillary lymph node. the superficial lymph nodes are large and soft compared with those of the domestic species, and each lymph centre usually contains only one or two large lymph nodes. koalas have a rostral mandibular lymph node which has not been described in other species, but lack popliteal and subiliac lymph nodes. ...19911769900
conservation genetics of the koala (phascolarctos cinereus). ii. limited variability in minisatellite dna sequences.we have examined variability in taqi and ecori restriction fragment sizes of dna from the koala (phascolarctos cinereus) using six hvr (hypervariable region) probes which reveal complex, individual-specific restriction patterns in humans and other species. frequency of band-sharing among unrelated koalas was extremely high. this result is likely to be a consequence of the history of near-extinction and artificial recolonization of the populations we have studied, rather than a general marsupial ...19911747097
semen characteristics in free-living koalas (phascolarctos cinereus).spermic electroejaculates (range in motile sperm/ejaculate, 0.50-122.9 x 10(6); mean +/- s.e.m., 38.6 +/- 4.9) were recovered from 47 of 48 adult koalas captured from 3 wild populations in australia. semen was characterized by (i) a high density of globular bodies, which prevented the estimation of sperm motility without dilution; (ii) a brownish colour; and (iii) an acidic ph. spermatozoa were categorized on the basis of 10 head forms, most cells being a curved or hooked shape. the koala popula ...19912056498
phenotypic characterization of co2-requiring strains of streptococcus bovis from koalas.we examined phenotypic characteristics of six mannitol-fermenting strains of streptococcus bovis, including two unusual co2-requiring strains isolated from koala feces. these strains did not grow in air, but grew in air supplemented with co2 and under reduced oxygen conditions. all six strains had the same biochemical characteristics, except that the co2-requiring strains did not produce beta-n-acetylglucosaminidase.19911746961
1h nmr spectroscopic survey of plasma and erythrocytes from selected marsupials and domestic animals of australia.1. 1h nmr spectra were acquired from whole plasma, intact erythrocytes, and ultrafiltrates of erythrocytes from nine native and eight introduced (domestic) australian animals; single-pulse, spin-echo and 2-dimensional spectra were obtained. the aim was to detect and at least semi-quantify metabolites in the samples and compare the profiles amongst the species. 2. the australian natives that were studied were all marsupials: greater brown bandicoot; bettong; eastern grey kangaroo; red kangaroo; k ...19911769206
tyzzer's disease (bacillus piliformis) in australian marsupials.tyzzer's disease (bacillus piliformis infection) was diagnosed in nine marsupials (six possums, a koala, a wombat and a dasyurid). all but two of the possums were captive. five of the seven marsupials, for which ages were recorded, were juvenile. affected marsupials were either found dead or were showing non-specific illness for up to two days before death. affected livers and hearts showed gross haemorrhage and scattered areas of white discolouration. microscopically, areas of coagulative necro ...19911779038
serological assessment of chlamydial infection in the koala by a slide eia technique.a rapid and simplified slide enzyme immunosorbent assay (eia) was developed for the diagnosis of chlamydial infection in the koala. hela 229 cells infected with koala strain chlamydia psittaci were fixed on the surface of multiwell slides and used as the antigen. the assay consisted of first reacting koala antiserum with the fixed c psittaci antigen, followed by reaction with biotinylated rabbit anti-koala igg, abc reagent and substrate. the chlamydial eia antibody titres obtained were compared ...19911807246
evaluation of an immunofluorescence test on direct smears of conjunctival and urogenital swabs taken from koalas for the detection of chlamydia psittaci.the chlamydia-cel vet if test (ccvit), a commercially available immunofluorescence test for use on direct smears of clinical specimens, was evaluated in a colony of 43 captive koalas. the test is based on a monoclonal antibody directed against the chlamydial common group specific lipopolysaccharide antigen. swabs were taken from conjuncitva and penis or urogenital sinus and used for direct smear evaluation and cell culture isolation. compared with isolation of the organism in cell culture, the c ...19911883293
chlamydial infection in a colony of captive koalas.forty three koalas in a captive colony were investigated for the presence of chlamydia psittaci infection and associated disease. swabs were taken from conjunctivae and urogenital sites for cell culture isolation of c psittaci and for cytological examination (direct smears) for chlamydial inclusions and evidence of inflammation. on the basis of cell culture isolation, 28 samples from 25 koalas were positive for c psittaci (that is, infected). three koalas were positive from both sites, 5 from co ...19911883294
purification and initial characterisation of koala immunoglobulins.the production of koala immunoglobulins (ig) was elicited by the immunisation of a koala (phascolarctos cinereus) with bovine serum albumin. this ig was then purified using the highly specific techniques of affinity chromatography. the purified protein was compared with a "potential" koala ig protein which was subsequently purified by protein g chromatography and both proteins were further characterised by agarose/sds-page and immunoelectrophoresis. results indicate that koalas do produce ig in ...19911949580
detection of chlamydia psittaci using dna probes and the polymerase chain reaction.fewer than 10(5) elementary bodies of chlamydia psittaci could be detected by using dna hybridisation with a plasmid probe specific for avian chlamydial strains. pcr amplification of chlamydial dna using primers specific for conserved regions of the major outer membrane protein gene enabled the detection of fewer than 10 elementary bodies. dna could be amplified from 22 of the 24 chlamydial strains tested including avian, feline, ovine, caprine, koala and lymphogranuloma venereum strains.19912037227
keratitis in free-ranging koalas (phascolarctos cinereus) on magnetic island, townsville.seventy free-ranging koalas (phascolarctos cinereus) from magnetic island (queensland, australia) underwent an ocular examination, blood collection and serological examination for chlamydia psittaci antibodies, and an examination of their teeth and genitalia. in 12 koalas long-standing unilateral keratitis was noted and in another 10 animals long-standing bilateral keratitis was observed. all animals were seronegative for chlamydia psittaci and apart from some nasal discharge and a variety of as ...19921380994
koala lymphoid cells: analysis of antigen-specific responses.bovine serum albumin (bsa) and ovine immunoglobulin (ovigg) were used to induce humoral immune responses in two koalas which were also painted with 2-4-dinitrofluorobenzene (dnfb) and subsequently tested for local delayed-type hypersensitivity (dth) reactions. the responses observed support the suggestion that the koala is 'immunologically lazy'. antibody responses to bsa and ovigg were not detected until 12 weeks after the initial antigen injection and antigen-specific in vitro proliferative re ...19921387489
comparison of nine antigen detection kits for diagnosis of urogenital infections due to chlamydia psittaci in koalas.chlamydia psittaci is the major cause of infectious disease in the koala (phascolarctos cinereus). it causes four disease syndromes in the koala, namely, conjunctivitis, rhinitis, cystitis, and infertility (females only). diagnosis of chlamydial infections in koalas relies primarily on isolation of the organism in cell culture. serology has generally not been useful, and little use has previously been made of the commercially available antigen detection kits. we examined the sensitivity, specifi ...19921452703
