Currently, there is a lack of surveys that report the occurrence of gastrointestinal parasites in the whiteheaded capuchin monkey (Cebus albifrons). We therefore assessed the presence and richness (= number of different parasite genera) of parasites in C. albifrons in wildlife refuges (n = 11) and in a free-ranging group near a human village (n = 15) in the Ecuadorian Amazon. In the 78 samples collected (median of 3 samples per animal), we identified a total of 6 genera of gastrointestinal parasites, representing protozoa, nematodes, acanthocephalans and cestodes. We observed a high prevalence (84%) across the 26 individuals, with the …

Baylisascaris Procyonis Prevalence In Raccoons (Procyon Lotor) And Its Relation To Landscape Features, Matthew E. Ingle, Stephen G. Dunbar, Jaynee L. Bartsch, Kyle J. Culbertson, Taylor A.

Raccoons (Procyon lotor) are the final host for raccoon roundworm (Baylisascaris procyonis). Raccoon roundworm is the leading cause of a dangerous neurological disease known as larva migrans encephalopathy. Land fragmentation occurs when natural environments are broken up by urban or agricultural landscapes. Raccoons thrive in urban environments, while raccoons in agricultural settings forage over larger areas than raccoons in urban settings do. Land fragmentation affects concentrations of B. procyonis parasites in intermediate hosts. We calculated the prevalence of raccoon roundworm in 9 townships of Greene and Clark Counties by necropsying 226 raccoon intestines. Prevalence is defined as the number of …

Does Baylisascaris Procyonis Phylogeny Correlate With That Of The Raccoon (Procyon Lotor), Matthew E. Ingle, Stephen G. Dunbar, Jaynee L. Bartsch, Kyle J. Culbertson, Taylor A. Fulton, Katherine R. Guffey, Aubrey J. Juris, Ashlie N. Nolan, Daniel P. Nordquist, Carrie E. Rowlands, Joshua A. Sitler

Baylisacaris procyonis, commonly known as the raccoon roundworm, is a parasite that inhabits the small intestine of the North American raccoon (Procyon lotor). Although humans do not typically become the definitive host, humans can become infected through handling soil containing eggs. B. procyonis can induce serious health complications in cases of human infection, including degenerative retinal and behavioral changes, coma, and even death. High prevalence of B. procyonis in a raccoon population increases the probability of transference to human hosts. In our study, we analyzed the genetic structure of B. procyonis harvested from raccoons of southwestern Ohio, and compared this …

Baylisascaris Procyonis Impacts Raccoon (Procyon Lotor) Diets, Matthew E. Ingle, Stephen G. Dunbar, Jaynee L. Bartsch, Kyle J. Culbertson, Taylor A. Fulton, Katherine R. Guffey, Aubrey J. Juris, Ashlie N. Nolan, Dan P. Nordquist, Carrie E. Rowlands, Joshua A. Sitler

Raccoons (Procyon lotor) are the definitive host for raccoon roundworms (Baylisascaris procyonis). Raccoon roundworm is responsible for a dangerous neurological disease known as larva migrans encephalopathy. Raccoons are omnivorous animals and rely on various food items. Dietary analyses help determine how a raccoon changes its diet in response to environmental features. Raccoons eat whatever food resource is most convenient and abundant. Parasite infections can potentially affect host eating habits in order to keep the host alive and active longer. In this study, we analyzed the diets of necropsied raccoons from ten townships of Clark and Greene Counties by examining their …

Does Baylisascaris Procyonis Impact Raccoon (Procyon Lotor) Genetics?, Matthew E. Ingle, Stephen G. Dunbar, Jaynee L. Bartsch, Kyle J. Culbertson, Taylor A. Fulton, Katherine R. Guffey, Aubrey J. Juris, Ashlie N. Nolan, Daniel P. Nordquist, Carrie E. Rowlands, Joshua A. Sitler

Raccoons (Procyon lotor) are the final host for raccoon roundworms (Baylisascaris procyonis). Raccoon roundworm is the leading cause of a dangerous neurological disease, known as larva migrans encephalopathy. Phylogenetic trees illustrate co-evolutionary events between species living in a symbiotic relationship with each other. Throughout the coevolution of host and parasite, many aspects of a population affect the way the members interact with one another and with symbiotic species. In order to evaluate the relationship between host and parasite in regards to diet, we isolated DNA from intestinal wall tissue, amplified a portion of exon 2 from MHC II, and sent …

Seroprevalence Of Antibodies Against Kaposi's Sarcoma-Associated Herpesvirus Among Hiv-Negative People In China, Tiejun Zhang, Zhenqiu Liu, Jun Wang, Veenu Minhas, Charles Wood, Gary M. Clifford, Na He, Silvia Franceschi

Nebraska Center for Virology: Faculty Publications

Background: Little information on the prevalence of Kaposi’s sarcoma associated herpesvirus (KSHV) among HIV-negative individuals is available from Asia.

Methods: In the present study, we report findings from a new survey of KSHV in 983 HIV-negative male migrants from Shanghai and their combination with previous similar surveys of 600 female migrants, 600 female sex-workers (FSW), 1336 sexually transmitted infection (STI) clinic male patients, 439 intravenous drug-users (IVDU), and 226 men having sex with men (MSM) from China. KSHV-specific antibodies against latent and lytic antigens were assessed using Sf9 and BC3 monoclonal immunofluorescence assay. Age-adjusted prevalence ratios (PR) and 95% confidence …

Cooccurrence Of Schistosoma Haematobium, Other Trematode Parasites, An Annelid (Chaetogaster Limnaei Limnaei), And A Nematode Parasite (Daubaylia Potomaca) In Bulinus Globosus, Ogochukwu Okeke, Patience Ubachukwu

Turkish Journal of Zoology

Cooccurrence of Schistosoma haematobium, other trematodes, Chaetogaster limnaei limnaei, and Daubaylia potomaca was investigated in Bulinus globosus collected at Nike Lake from October 2011 to September 2012. The snail sizes as well as the numbers of these organisms were recorded. Single infections of S. haematobium, other trematodes, C. limnaei limnaei, and D. potomaca were 0.3%, 46.38%, 1.03%, and 2.66%. Coinfection of S. haematobium-C. limnaei limnaei was 0.3% while that of S. haematobium-other trematodes was 0.15%. Coinfections of C. limnaei limnaei-other trematodes and D. potomaca-other trematodes were 2.16% each. There was no cooccurrence of C. limnaei limnaei-D. potomaca or S. haematobium-D. …

Infectious Epididymitis Caused By Brucella Ovis In Croatian Sheep Flocks, Zeljko Cvetnic, Maja Zdelar-Tuk, Sanja Duvnjak, Miroslav Benic, Zeljko Mihaljevic, Boris Habrun, Irena Reil, Marija Cvetnic, Silvio Spicic

Turkish Journal of Veterinary & Animal Sciences

The distribution of infection by the species Brucella ovis in rams and abortion cases in sheep in Croatia was investigated in the period from 2011 to 2015. The investigation relied on serological testing in rams and sheep after abortion conducted using a complement fixation test and immunosorbent assay conducted with bacteriological testing of the testes in seropositive rams and aborted material. Seropositive reactions were confirmed in 1100 (6%) of rams samples and in 12 (2.3%) of ewe samples. Isolated strains were also confirmed on the molecular level. In 10 (45.5%) animals asymmetry of the scrotum and unilateral enlargement of the …
