Survey of Antibodies to Trypanosoma cruzi and Leishmania spp. in Gray and Red Fox Populations From North Carolina and Virginia

Rosypal, A. C.; Tripp, S.; Lewis, S.; Francis, J.; Stoskopf, M. K.; Larsen, R. S.; Lindsay, D. S. (American Society of Parasitology, 2010-12)

American trypanosomiasis and leishmaniasis are caused by related hemoflagellate parasites, Trypanosoma cruzi and Leishmania spp., which share several common host species. Both zoonotic protozoans are endemic in the United ...

Protective immune response to experimental infection with Sarcocystis neurona in C57BL/6 mice

Witonsky, Sharon G.; Gogal, Robert M.; Duncan, Robert B.; Lindsay, David S. (American Society of Parasitology, 2003-10)

Immunocompetent C57BL/6 mice were infected with Sarcocystis neurona merozoites to assess the protective immune response to active infection. Using a direct agglutination test, all infected mice seroconverted to S. neurona ...

Vaccination of mice with Neospora caninum: Response to oral challenge with Toxoplasma gondii oocysts

Lindsay, D. S.; Lenz, S. D.; Dykstra, C. C.; Blagburn, B. L.; Dubey, J. P. (American Society of Parasitology, 1998-04)

Neospora caninum is a protozoan parasite that can cause severe disease in mammals. Two experiments were conducted to examine the effects of subcutaneous (s.c.) vaccination with Hank's balanced salt solution (HBSS), 1 x ...

Variation in Eimeria oocyst count and species composition in weanling beef heifers

Lucas, A. S.; Swecker, W. S.; Scaglia, G.; Lindsay, D. S.; Zajac, A. M. (American Society of Parasitology, 2006-10)

Rectal fecal samples were collected daily on 10 consecutive days in November 2004 from I I weaned beef heifers to assess daily variation in fecal oocyst count and species composition. Subsequent samples were collected from ...

Effects of high-pressure processing on Toxoplasma gondii tissue cysts in ground pork

Lindsay, D. S.; Collins, M. V.; Holliman, D.; Flick, G. J.; Dubey, J. P. (American Society of Parasitology, 2006-02)

Ingestion of Toxoplasma gondii tissue Cysts can result in severe disease in immunocompromised individuals and pregnant women. Treatment of mean and meat products to eliminate. viable T. gondii tissue cysts would provide a ...

Serological Survey for Antibodies to Encephalitozoon cuniculi in Ownerless Dogs From Urban Areas of Brazil and Colombia

Lindsay, D. S.; Goodwin, D. G.; Zajac, A. M.; Cortes-Vecino, J. A.; Gennari, S. M.; Rosypal, A. C.; Dubey, J. P. (American Society of Parasitology, 2009-06)

There are 3 strains of Encephalitozoon cuniculi that occur in mammals. Strain III is associated with clinical disease in dogs, although some can be asymptomatic carriers and excrete spores in their urine. Several cases of ...

Horses experimentally infected with sarcocystis neurona develop altered immune responses in vitro

Witonsky, Sharon G.; Ellison, Siobhan; Yang, Jibing; Gogal, Robert M.; Lawler, Heather; Suzuki, Yasuhiro; Sriranganathan, Namalwar; Andrews, Frank; Ward, Daniel; Lindsay, David S. (American Society of Parasitology, 2008-10)

Equine protozoal myeloencephalitis (EPM) due to Sarcocystis neurona infection is I of the most common neurologic diseases in horses in the United States. The mechanisms by which most horses resist disease, as well as the ...

Complete development of the porcine coccidium Isospora suis Biester, 1934 in cell cultures

Lindsay, D. S.; Quick, D. P.; Steger, A. M.; Toivio-Kinnucan, M. A.; Blagburn, B. L. (American Society of Parasitology, 1998-06)

Development from inoculated sporozoites to unsporulated oocysts of Isospora suis Biester, 1934 is described in a swine testicular (ST) cell line. Sporozoites penetrated ST cells within 1 hr postinoculation (PI). Development ...

Besnoitia oryctofelisi n. sp (Protozoa : Apicomplexa) from domestic rabbits

Dubey, J. P.; Sreekumar, C.; Lindsay, D. S.; Hill, D.; Rosenthal, B. M.; Venturini, L.; Venturini, M. C.; Greiner, E. C. (Cambridge University Press, 2003-06)

A species of Besnoitia from naturally infected rabbits from Argentina was propagated experimentally in mice, gerbils, rabbits, cats, and cell cultures. Cats fed tissue cysts from rabbits shed oocysts with a prepatent period ...

Isolates of Sarcocystis falcatula-like organisms from South American opossums Didelphis marsupialis and Didelphis albiventris from Sao Paulo, Brazil

Dubey, J. P.; Lindsay, D. S.; Rosenthal, B. M.; Kerber, C. E.; Kasai, N.; Pena, H. F. J.; Kwok, O. C. H.; Shen, S. K.; Gennari, S. M. (American Society of Parasitology, 2001-12)

Isolates of Sarcocystis falcatula-like organisms from South American opossums were characterized based on biological and morphological criteria. Sporocysts from intestinal scrapings of 1 Didelphis marsupialis and 8 Didelphis ...
