giardia infection in animals in poznań zoo.one hundred and eighty-four faecal samples from 170 animals of 82 different species in poznań zoo were examined with direct wet mounts in physiological saline and permanent smears stained with iron-haematoxylin. giardia spp. cysts were found in one chimpanzee, four marmosets, two north american porcupines, a european wild cat and a serval. the infection in the porcupines was very intense and resistant to metronidazole treatment.19836415896
association of malassezia (pityrosporum) pachydermatis with sarcoptic mange in new york state.malassezia (pityrosporum) pachydermatis consistently accompanied sarcoptic mange in all red foxes (vulpes fulva), porcupines (erethizon dorsatum), and coyotes (canis latrans) examined. this yeastlike microorganism has not heretofore been reported on any of these hosts. its presence on the exoskeleton of sarcoptes scabiei taken from these animals suggests a carrier role for the mite. the yeast may be saprophytic or a secondary pathogen.19806780699
dipetalonema from the eye of a man in oregon, u.s.a. a case report.a 21-mm filarial worm appeared suddenly in the anterior chamber of the right eye of a 32-year-old man in western oregon. by a simultaneous irrigation-aspiration procedure, it was removed alive and only slightly damaged and was identified as a female dipetalonema in the fourth stage of development. it was the third such case to be reported from western oregon. in this and one other case the worms were morphologically similar to adult worms identified as dipetalonema arbuta highby 1943 from the bo ...19807189968
ecology of porcupines (erethizon dorsatum) and colorado tick fever virus in rocky mountain national park, 1975-1977.the involvement of porcupines, erethizon dorsatum (l.), in the ecology of colorado tick fever (ctf) virus in rocky mountain national park was investigated from 1975 to 1977. porcupine dens and feeding activity were found mostly on rocky knolls or on south-facing slopes within open stands of the montane coniferous forest, and 20 adult porcupines were trapped or captured by hand at those locations. an average of 24.6 +/- 5.4 adult dermacentor andersoni stiles ticks were found per animal (annual ra ...19938433332
hepatic capillariasis (capillaria hepatica) in porcupines (erethizon dorsatum) in pennsylvania.tissues of 53 adult porcupines (erethizon dorsatum) from pennsylvania were obtained for histopathologic examination. hepatic capillariasis was recorded in 9% of the porcupines. an additional 11% of the liver sections showed lesions that were compatible with migration by capillaria hepatica. because only 1 section of the liver per animal was examined microscopically, the documented prevalence of c. hepatica in pennsylvania is considered conservatively low. however, this condition was subclinical, ...200011021437
digestibility, nitrogen excretion, and mean retention time by north american porcupines (erethizon dorsatum) consuming natural forages.north american porcupines (erethizon dorsatum) subsist predominantly on low-protein, high-fiber, high-tannin diets. therefore, we measured the porcupine's ability to digest dry matter, fiber, and protein by conducting digestion trials on eight natural forages and one pelleted ration varying in concentration of fiber, nitrogen, and tannins. on these diets, dry matter intake ranged from 5 to 234 g/kg(0.75)/d and dry matter digestibility ranged from 62% to 96%. porcupines digested highly lignified ...200011121350
occurrence of dermacentor variabilis (acari: ixodidae) around a porcupine (rodentia: erthethizontidae) carcass at camp ripley, minnesota.in may 2000, a dead porcupine (erethizon dorsatum culiver) was found on an infrequently traveled dirt road at camp ripley, mn. the presence of late instar calliphoridae suggested that the porcupine died within the past 4 to 7 d. adult carrion (silphidae) and rove (staphylinidae) beetles were observed under the carcass. in june, a large number of adult american dog ticks, dermacentor variabilis (say), were observed questing on the porcupine and the surrounding grass. six zones were established ar ...200312597663
observation of helicobacter-like organisms in gastric mucosa of grey foxes (urocyon cinereoargenteus) and bobcats (lynx rufus).archival specimens of gastric mucosa of 10 raccoons (procyon lotor), 9 porcupines (erethizon dorsatum), 6 grey foxes (urocyon cinereoargenteus), 6 bobcats (lynx rufus), 4 skunks (mephitis mephitis), and 3 black bears (ursus americanus) were microscopically examined for evidence of helicobacter-like organisms. such organisms were seen in the specimens from the grey foxes and bobcats only. histochemical stains (modified steiner and carbol fuchsin methods) revealed long spiral organisms within lumi ...200415188962
behavior, movements, and demographics of rabid raccoons in ontario, canada: management implications.during 1999-2003, 127 cases of raccoon variant rabies were reported in raccoons (procyon lotor) and striped skunks (mephitis mephitis) in ontario, canada. raccoons accounted for 98% (125/127) of the reported cases with behaviors/conditions including aggression, fighting with dogs, ataxia, vocalizations, appearance of being sick, and the presence of porcupine (erethizon dorsatum) quills. seventy-eight percent of the rabid raccoons were adults. juveniles were underrepresented (22%) compared with t ...200617092890
prevalence of cryptosporidium species in wildlife populations within a watershed landscape in southeastern new york state.a cross-sectional study was conducted to determine the prevalence of cryptosporidium in wildlife in the new york city (nyc) watershed in southeastern new york state. a total of 6227 fecal samples were collected and evaluated from 5892 mammals (38 species), 263 birds (14 species), 2 reptiles (2 species), 8 amphibians (4 species), and 62 fish (15 species). cryptosporidium was detected in 30 species. of the species found positive for cryptosporidium, 16 represented new records for this parasite-alo ...200717466459

traumatic, degenerative, and developmental lesions in wolves and coyotes from saskatchewan.a retrospective review was done of traumatic and osseous lesions in 241 wolves (canis lupus) and 316 coyotes (canis latrans) necropsied at the university of saskatchewan between 1971 and 1990. most lesions were the result of interspecific conflict. the most frequently occurring lesion in wolves was fracture of one or more bones, primarily ribs. lesions were healed in most cases and appeared to be compatible with injuries caused by prey animals. one wolf, found dead, died as a result of thoracic ...19921602579
cerebral larva migrans caused by baylisascaris spp. in a free-ranging north american porcupine ( erethizon dorsatum ).a free-ranging north american porcupine ( erethizon dorsatum ) from utah, us, exhibited neurologic symptoms and was submitted for necropsy. histologic examination of the brain revealed severe encephalitis with an intralesional nematode larva consistent with baylisascaris spp. neurologic larva migrans had not been reported in free-ranging porcupines, or from wildlife in utah.201627314480
population dynamics of a northern-adapted mammal: disentangling the influence of predation and climate change.community structure and interspecific interactions are particularly vulnerable to rapidly changing climatic regimes. recent changes in both climate and vertebrate community assemblages have created a unique opportunity to examine the impacts of two dynamic forces on population regulation. we examined the effects of warming winter conditions and the reestablishment of a previously extirpated predator, the fisher (martes pennanti), on regulatory mechanisms in a northern-adapted mammal, the porcupi ...201526552263
intrauterine fetal death with subsequent quill exfoliation and dissemination in a north american porcupine (erethizon dorsatum).an adult female, wild north american porcupine (erethizon dorsatum) presented with bilateral cataracts and naso-ocular discharge. a pregnancy was identified by radiography with a near-full-term fetus, which was delivered stillborn 4 wk later with hard, developed quills. at that time, a repeated examination and further imaging, including computed tomography, demonstrated a uterine mass that was identified as a choriocarcinoma following ovariohysterectomy. additionally, numerous exfoliated quills ...201324450079
winter as a nutritional bottleneck for north american porcupines (erethizon dorsatum).north american porcupines are distributed across a wide variety of habitats where they consume many different species of plants. winter is a nutritional bottleneck for northern populations, because porcupines remain active when environmental demands are high and food quality is low. we used captive porcupines to examine physiological responses to low-quality diets at high energy demands during winter at ambient temperatures as low as -39 degrees c. we did not observe an endogenous pattern of bod ...201020306197
trophoblast-like cells in the tissues of porcupines (erethizon dorsatum).during development and subsequent field evaluation of an oral vaccinia-rabies glycoprotein (v-rg) recombinant virus vaccine, 53 adult porcupines (erethizon dorsatum; 38 females and 15 males) were examined. microscopic examinations revealed the presence of giant epitheloid cells in various tissues (adrenal glands, spleen, liver, and lungs) of 4 (11%) female animals. these giant cells were approximately 20 times the size of the surrounding cells of the parenchyma. the cells were found singly and w ...200818487503
functional anatomy of the limbs of erethizontidae (rodentia, caviomorpha): indicators of locomotor behavior in miocene porcupines.functional analysis of the limb bones of the erethizontid steiromys duplicatus, one of the most abundant miocene porcupines from patagonia, provides evidence to infer their locomotor behavior. remains of the giant neosteiromys pattoni (late miocene of northeast argentina) are also analyzed. osteological and myological features of extant porcupines were evaluated and used as a model to interpret the functional significance of miocene species' limbs. several features in erethizontids are compatibl ...200818157864
hepatic lipidosis and other test findings in two captive adult porcupines (erethizon dorsatum) dying from a "sudden death syndrome".routine postmortem examination and histologic evaluation of tissue sections demonstrated hepatic lipidosis (hl) in 2 adult captive porcupines with a history of sudden death. the male porcupine had a markedly enlarged pale liver that microscopically showed large unilocular vacuoles within hepatocellular cytoplasm. the periparturient female had similar but less marked hepatic lesions and an incidental pulmonary mycosis. these findings suggest hl as an important differential of spontaneous death in ...200717998565

diagnosis and successful treatment of a potentially zoonotic dermatophytosis caused by microsporum gypseum in a zoo-housed north american porcupine (erethizon dorsatum).a female north american porcupine ( erethizon dorsatum ) was evaluated for a unilateral pedal crusting and alopecic dermatopathy. fungal culture and histopathology testing revealed microsporum gypseum dermatophytosis. treatment with topical miconazole was initiated and then discontinued after 9 days and changed to oral terbinafine. twenty-eight days after initial examination, clinical signs were improving, and fungal cultures of the front foot, muzzle, and noninfected area along the dorsum were ...201728749293
genetic characterization of sarcoptes scabiei from black bears (ursus americanus) and other hosts in eastern united states.since the early 1990s there has been an increase in the number of cases and geographic expansion of severe mange in the black bear (ursus americanus) population in pennsylvania. although there are 3 species of mites associated with mange in bears, sarcoptes scabiei has been identified as the etiologic agent in these pennsylvania cases. historically s. scabiei-associated mange in bears has been uncommon and sporadic although it is widespread and relatively common in canid populations. to better u ...201728639466
taxonomic differences of gut microbiomes drive cellulolytic enzymatic potential within hind-gut fermenting mammals.host diet influences the diversity and metabolic activities of the gut microbiome. previous studies have shown that the gut microbiome provides a wide array of enzymes that enable processing of diverse dietary components. because the primary diet of the porcupine, erethizon dorsatum, is lignified plant material, we reasoned that the porcupine microbiome would be replete with enzymes required to degrade lignocellulose. here, we report on the bacterial composition in the porcupine microbiome using ...201729281673
the history of barbed sutures.ligatures have been used for millennia to close wounds. sterilization and synthetic polymers that degrade in a commensurate fashion with wound healing have been the most significant improvements in these age-old devices. however, the constricting loop of a traditional suture and subsequent ischemia ("approximate, don't strangulate") still account for the most common cause of wound dehiscence-necrosis. inspired by the quill of the north american porcupine, i envisioned a bidirectional array of ba ...201324084875
microstructured barbs on the north american porcupine quill enable easy tissue penetration and difficult removal.north american porcupines are well known for their specialized hairs, or quills that feature microscopic backward-facing deployable barbs that are used in self-defense. herein we show that the natural quill's geometry enables easy penetration and high tissue adhesion where the barbs specifically contribute to adhesion and unexpectedly, dramatically reduce the force required to penetrate tissue. reduced penetration force is achieved by topography that appears to create stress concentrations along ...201223236138
