ferrets as sentinels of the presence of pathogenic cryptococcus species in the mediterranean environment. | cryptococcus gattii is a pathogenic environmental yeast that is considered to be emerging in different areas of the world including the mediterranean basin. exposure to infection might be more likely in animals than in human beings, given their closer relationship with the natural habitat of the yeast, vegetation and soil. thus, animals, and especially pets, can act as indicators of the presence of this yeast in a determined area. domestic ferrets (mustela putorius furo) have become common pets ... | 2014 | 24962111 |
neuroglobin of seals and whales: evidence for a divergent role in the diving brain. | although many physiological adaptations of diving mammals have been reported, little is known about how their brains sustain the high demands for metabolic energy and thus o(2) when submerged. a recent study revealed in the deep-diving hooded seal (cystophora cristata) a unique shift of the oxidative energy metabolism and neuroglobin, a respiratory protein that is involved in neuronal hypoxia tolerance, from neurons to astrocytes. here we have investigated neuroglobin in another pinniped species ... | 2012 | 22864183 |
auditory nerve fibre responses in the ferret. | the ferret (mustela putorius) is a medium-sized, carnivorous mammal with good low-frequency hearing; it is relatively easy to train, and there is therefore a good body of behavioural data detailing its detection thresholds and localization abilities. however, despite extensive studies of the physiology of the central nervous system of the ferret, even extending to the prefrontal cortex, little is known of the functioning of the auditory periphery. here, we provide an insight into this peripheral ... | 2012 | 22694786 |
detection, prevalence and phylogenetic relationships of demodex spp and further skin prostigmata mites (acari, arachnida) in wild and domestic mammals. | this study was conceived to detect skin mites in social mammals through real-time qpcr, and to estimate taxonomic demodex and further prostigmata mite relationships in different host species by comparing sequences from two genes: mitochondrial 16s rrna and nuclear 18s rrna. we determined the mite prevalence in the hair follicles of marmots (13%) and bats (17%). the high prevalence found in marmots and bats by sampling only one site on the body may indicate that mites are common inhabitants of th ... | 2016 | 27802314 |
an atypical distribution of lactate dehydrogenase isoenzymes in the hooded seal (cystophora cristata) brain may reflect a biochemical adaptation to diving. | the brains of some diving mammals can withstand periods of severe hypoxia without signs of deleterious effects. this may in part be due to an enhanced cerebral capacity for anaerobic energy production. here, we have tested this hypothesis by comparing various parameters of the lactate dehydrogenase (ldh) in the brain of the hooded seal (cystophora cristata) with those in the brains of the ferret (mustela putorius furo) and mouse (mus musculus). we found that mrna and protein expression of lactat ... | 2016 | 26820264 |
