| baylisascaris procyonis demography and egg production in a california raccoon population. | california has more reported human raccoon roundworm cases than any other state due to large and overlapping human and raccoon populations. infection by this parasite, baylisascaris procyonis , is relatively benign in raccoons but can cause severe pathology in other species. disease risk is driven by environmental egg contamination which increases with raccoon density, worm intensity, and worm prevalence. to improve knowledge about risk to humans and other species, 189 raccoons from southern cal ... | 2016 | 27556367 |
| variable infection dynamics in four peromyscus species following experimental inoculation with baylisascaris procyonis. | wild rodents such as peromyscus spp. are intermediate hosts for the zoonotic ascarid baylisascaris procyonis (raccoon roundworm), and previous studies indicate peromyscus leucopus (white-footed mouse) likely serves an important role in parasite ecology. natural infections have been sporadically identified in a few peromyscus spp., but no data are available on differences in susceptibility among the many other species. we compared survival and infection dynamics of b. procyonis in 4 species ( p. ... | 2016 | 27351237 |
| raccoon roundworm eggs near homes and risk for larva migrans disease, california communities. | the raccoon roundworm, baylisascaris procyonis, is increasingly recognized as a cause of serious or fatal larva migrans disease in humans and animals. we assessed the potential for infection in three northern california communities by determining the density and distribution of raccoon latrines, where transmission primarily occurs, and the prevalence of eggs at private residences. we collected fecal samples from 215 latrines and found that 44%-53% of the latrines contained b. procyonis eggs and ... | 2003 | 14720389 |
| baylisascaris procyonis (nematoda: ascarididae) larva migrans in free-ranging wildlife in orange county, california. | baylisascaris procyonis is well recognized as a cause of visceral (vlm), ocular, and neural (nlm) larva migrans in birds and mammals, including man. a study of the prevalence of larva migrans in free-ranging wildlife associated with raccoon latrines as well as a retrospective study of wildlife mortalities with neurological disease was conducted in 2000 in orange county, california. eighty-seven birds of 18 species and 64 mammals of 8 species were found to have nlm or vlm or both. nlm clinical si ... | 2002 | 12054001 |
| baylisascaris procyonis (nematoda: ascaridoidea) eggs in raccoon (procyon lotol) latrine scats in orange county, california. | baylisascaris procyonis is the common intestinal nematode of the raccoon and is well-recognized as a cause of visceral, ocular, and neural larva migrans in many species of wild and domestic birds and mammals, including humans. to develop data on the prevalence of b. procyonis in orange county, california, 800 distinct raccoon latrine sites were sampled in 4 spatial zones from 15 january to 31 december 2000. counts of fecal eggs per gram (epg) were determined and evaluated with reference to spati ... | 2002 | 12053964 |

| baylisascaris procyonis-associated meningoencephalitis in a previously healthy adult, california, usa. | after severe neurocognitive decline developed in an otherwise healthy 63-year-old man, brain magnetic resonance imaging showed eosinophilic meningoencephalitis and enhancing lesions. the patient tested positive for antibodies to baylisascaris spp. roundworms, was treated with albendazole and dexamethasone, and showed improvement after 3 months. baylisascariasis should be considered for all patients with eosinophilic meningitis. | 0 | 27434260 |
| a presumptive case of baylisascaris procyonis in a feral green-cheeked amazon parrot (amazona viridigenalis). | a feral green-cheeked amazon parrot (amazona viridigenalis), also known as the red-crowned amazon, with generalized neurologic symptoms was found in pasadena in southern california and brought in for treatment. the bird was refractory to a wide variety of medications and supportive treatment. tests for polyoma virus, psittacine beak and feather disease virus, and west nile virus as well as chlamydophila psittaci were negative. hospitalized and home care continued for a total of 69 days. the bird ... | 2014 | 24712176 |
| seroprevalence of baylisascaris procyonis infection among humans, santa barbara county, california, usa, 2014-2016. | baylisascaris procyonis (raccoon roundworm) infection is common in raccoons and can cause devastating pathology in other animals, including humans. limited information is available on the frequency of asymptomatic human infection. we tested 150 adults from california, usa, for b. procyonis antibodies; 11 were seropositive, suggesting that subclinical infection does occur. | 2017 | 28726612 |
| diffuse unilateral subacute neuroretinitis. morphometric, serologic, and epidemiologic support for baylisascaris as a causative agent. | several nematodes have been postulated as etiologic agents in diffuse unilateral subacute neuroretinitis (dusn), but the cause of this condition remains uncertain. the authors report the first case of dusn from the western united states (northern california), along with morphometric, serologic, and epidemiologic evidence supporting baylisascaris procyonis as its cause. | 1993 | 8233397 |
| baylisascaris procyonis (nematoda: ascaridae) in raccoons (procyon lotor) in orange county, california. | baylisascaris procyonis is one of the common nematodes of the raccoon (procyon lotor), being well recognized as a cause of visceral, ocular, and neural larval migrans in many species of wild and domestic birds and mammals, including humana. between january 15 and december 31, 2000 in orange county, ca, 640 raccoons (p. lotor) were live-trapped in four spatial distributions zones, and b. procyonis egg shedding prevalence and fecal egg per gram (epg) counts were determined in relation to spatial d ... | 2001 | 12653152 |
