| detection of anti-parelaphostrongylus tenuis antibodies in experimentally infected and free-ranging moose (alces alces). | confirming parelaphostrongylus tenuis infection in moose (alces alces) and other susceptible hosts is difficult. an enzyme-linked immunosorbent assay (elisa) was developed using the excretory-secretory (es) products of third-stage p. tenuis larvae (es-elisa) and the test applied to serum samples obtained from seven moose calves (5-9.5 mo old) given infective larvae (l3) in doses approximating those likely to be received in nature (3-30 l3). anti-p. tenuis immunoglobulin g antibodies were detecte ... | 2002 | 12528449 |
| trace elements in moose (alces alces) found dead in northwestern minnesota, usa. | the moose (alces alces) population in bog and forest areas of northwestern minnesota has declined for more than 25 years, and more recently the decline is throughout northwestern minnesota. both deficiencies and elevations in trace elements have been linked to the health of moose worldwide. the objective of this study was to evaluate whether trace element toxicity or deficiency may have contributed to the decline of moose in northwestern minnesota. livers of 81 moose found dead in northwestern m ... | 2004 | 15325160 |
| landscape influence on spatial patterns of meningeal worm and liver fluke infection in white-tailed deer. | parasites that primarily infect white-tailed deer (odocoileus virginianus), such as liver flukes (fascioloides magna) and meningeal worm (parelaphostrongylus tenuis), can cause morbidity and mortality when incidentally infecting moose (alces alces). ecological factors are expected to influence spatial variation in infection risk by affecting the survival of free-living life stages outside the host and the abundance of intermediate gastropod hosts. here, we investigate how ecology influenced the ... | 2015 | 25498206 |
| necropsy findings in 62 opportunistically collected free-ranging moose (alces alces) from minnesota, usa (2003-13). | the minnesota, us moose population has declined dramatically since the 1990s. all 54 carcasses of moose that died of unknown cause or were euthanized by gun shot by tribal or department of natural resources personnel because of perceived signs of illness between 2003 and 2013 and eight carcasses of moose that died from vehicular accidents between 2009 and 2013 were submitted to the minnesota veterinary diagnostic laboratory and included in our study. the majority of the animals were underweight ... | 2015 | 25390764 |
| seroprevalence, isolation, first genetic characterization of toxoplasma gondii, and possible congenital transmission in wild moose from minnesota, usa. | toxoplasma gondii infections are widespread in white-tailed deer (odocoileus virginianus) but little is known of its prevalence in other cervids in the usa. moose (alces alces) is a popular large game animal, hunted for its meat and trophy antlers. here, we report seroprevalence, isolation, and genetic characterization of t. gondii from moose from minnesota. antibodies against t. gondii were detected in 8 of 79 (10%) moose tested by the modified agglutination test (mat 1:25 or higher). the myoca ... | 2016 | 26472716 |
| winter body condition of moose (alces alces) in a declining population in northeastern minnesota. | assessments of the condition of moose (alces alces) may be particularly informative to understanding the dynamics of populations and other influential factors. during february-march 2003 to 2005, we assessed the nutritional condition of 79 moose (39 females, 40 males) in northeastern minnesota by body condition scoring (bcs(f), scale of 0-10); 67 of these by were assessed by ultrasonographic measurements of rump fat (maxfat), which was used to estimate ingesta-free body fat (ifbf) in all but two ... | 2011 | 21269994 |
| time series sightability modeling of animal populations. | logistic regression models-or "sightability models"-fit to detection/non-detection data from marked individuals are often used to adjust for visibility bias in later detection-only surveys, with population abundance estimated using a modified horvitz-thompson (mht) estimator. more recently, a model-based alternative for analyzing combined detection/non-detection and detection-only data was developed. this approach seemed promising, since it resulted in similar estimates as the mht when applied t ... | 2018 | 29329309 |
