| hymenopteran parasitoids of forensic importance: host associations, seasonality, and prevalence of parasitoids of carrion flies in western australia. | a 2-yr survey of hymenopteran parasitoids associated with carrion-breeding flies was conducted to establish the parasitoid species of potential forensic significance in western australia. host associations, seasonality, and rates of parasitism in the field were examined to assess the value of the identified parasitoids as forensic indicators of time since death. four species of parasitoid emerged from dipteran specimens collected from carcasses: tachinaephagus zealandicus ashmead (encryptidae), ... | 2009 | 19769056 |
| annual and seasonal patterns of insect succession on decomposing remains at two locations in western australia. | this study considered annual, seasonal and shorter term variation in patterns of insect succession onto decomposing remains at two contrasting locations in western australia, bushland and agricultural. the degree of consistency in insect succession patterns over spatial and temporal scales was evaluated through multivariate analysis of occurrence-based distance matrices. insect assemblages were strongly correlated between locations, within corresponding time periods, indicating that patterns of ... | 2009 | 19836175 |
| identification of novel and zoonotic cryptosporidium species in marine fish. | little is known about the prevalence and genotypes of cryptosporidium in fish. the present study investigated the prevalence of cryptosporidium species in cultured fingerlings (n=227), wild freshwater (n=227) and wild marine/estuarine species (n=255) of fish in western australia by pcr amplification at the 18s rrna locus. results revealed a low prevalence of cryptosporidium infection in fish hosts; 0.8% (6/709). four species of cryptosporidium were identified including c. parvum, c. xiaoi and pi ... | 2010 | 20031326 |
| preliminary studies into the characterization of chemical markers of decomposition for geoforensics. | in this paper, we report the results of our preliminary studies into chemical characterization of the fluids produced during decomposition in the absence of a soil matrix. pig (sus domestica) carcasses were used to model the human decomposition process in two separate locations, western australia (perth) and canada (oshawa). analysis involved simple dilution and filtration of the decomposition fluids followed by gas chromatography-mass spectrometry. several previously unreported compounds were d ... | 2010 | 20070470 |
| forensically significant scavenging guilds in the southwest of western australia. | estimation of time since death is an important factor in forensic investigations and the state of decomposition of a body is a prime basis for such estimations. the rate of decomposition is, however, affected by many environmental factors such as temperature, rainfall, and solar radiation as well as by indoor or outdoor location, covering and the type of surface the body is resting upon. scavenging has the potential for major impact upon the rate of decomposition of a body, but there is little d ... | 2010 | 20171028 |
| high prevalence of rickettsia gravesii sp. nov. in amblyomma triguttatum collected from feral pigs. | a survey of ectoparasites on feral pigs identified two commonly occurring ixodid tick species; amblyomma triguttatum triguttatum and ixodes australiensis. molecular screening of a. t. triguttatum and i. australiensis for the presence of rickettsia species detected the presence of rickettsiae belonging to the spotted fever group (sfg) in 78.4% of screened a. t. triguttatum. none of the screened i. australiensis were positive for rickettsiae. sequence analysis of the glta and ompa loci of positive ... | 2010 | 20488632 |
| molecular characterization of cryptosporidium and giardia in pre-weaned calves in western australia and new south wales. | a total of 364 fecal specimens from randomly selected pre-weaned calves, aged up to 4 months, from 5 different farms in the south of western australia and 1 farm from new south wales were screened for the presence of cryptosporidium and giardia using pcr. there were substantial differences in prevalence between the farms and the overall prevalence was 22.3% (81/364) and 26.9% (98/364) respectively for cryptosporidium and giardia. for cryptosporidium, 70 positives were identified at the 18s locus ... | 2010 | 21130578 |
| porcine circovirus-associated disease in weaner pigs in western australia. | to report the occurrence and pathology of porcine circovirus type 2 (pcv2)-associated disease (pcvad) of postweaning pigs in two australian pig herds. | 2011 | 21418168 |
| first report of a trichinella papuae infection in a wild pig (sus scrofa) from an australian island in the torres strait region. | multiple trichinella species are reported from the australasian region although mainland australia has never confirmed an indigenous case of trichinella infection in humans or animals. wildlife surveys in high-risk regions are essential to truly determine the presence or absence of trichinella, but in mainland australia are largely lacking. in this study, a survey was conducted in wild pigs from mainland australia's cape york peninsula and torres strait region for the presence of trichinella, gi ... | 2011 | 22030374 |
| effective surveillance strategies following a potential classical swine fever incursion in a remote wild pig population in north-western australia. | early disease detection and efficient methods of proving disease freedom can substantially improve the response to incursions of important transboundary animal diseases in previously free regions. we used a spatially explicit, stochastic disease spread model to simulate the spread of classical swine fever in wild pigs in a remote region of northern australia and to assess the performance of disease surveillance strategies to detect infection at different time points and to delineate the size of ... | 2014 | 23294519 |
