| parastrongylus (=angiostrongylus) cantonensis now endemic in louisiana wildlife. | parastrongylus (=angiostrongylus) cantonensis, a lung worm of rats, was first reported in the united states in 1987, with a probable introduction by infected rats from ships docking in new orleans, louisiana, during the mid-1980s. since then, it has been reported in nonhuman primates and a boy from new orleans, and in a horse from picayune, mississippi, a distance of 87 km from new orleans. parastrongylus cantonensis infection is herein reported in a lemur (varencia variegata rubra) from new ibe ... | 2002 | 12435151 |
| serologic evidence of exposure of wild mammals to flaviviruses in the central and eastern united states. | serosurveys were conducted to obtain flavivirus and west nile virus (wnv) seroprevalence data from mammals. sera from 513 small- and medium-sized mammals collected during late summer and fall 2003 from colorado, louisiana, new york, ohio, and pennsylvania were screened for flavivirus-specific antibodies. sera samples containing antibody to flaviviruses were screened for wnv-specific antibodies by epitope-blocking enzyme-linked immunosorbent assays and confirmed with plaque reduction neutralizati ... | 2005 | 15891139 |
| serologic evidence of west nile virus infection in free-ranging mammals, slidell, louisiana, 2002. | after an outbreak of west nile virus (wnv) infections in slidell, louisiana, in 2002, we detected neutralizing antibodies to wnv in 13 of 120 mammals, representing five of six species sampled. seroprevalence was measured in opossum, didelphis virginiana (75%, n = 8), raccoons, procyon lotor (60%, n = 5), black rats, rattus rattus (6%, n = 36), hispid cotton rats, sigmodon hispidus (4%, n = 24), and eastern gray squirrels, sciurus carolinensis (2%, n = 43). | 2005 | 16187899 |
| serologic evidence of west nile virus exposure in north american mesopredators. | sera from 936 mammalian mesopredators (virginia opossums, gray foxes, striped skunks, hooded skunks, raccoons, a bobcat, and a red fox) were collected during 2003 and 2004 in california, arizona, texas, louisiana, ohio, and wyoming and screened for flavivirus-specific antibodies by an epitope-blocking enzyme-linked immunosorbent assay (blocking elisa). serum samples positive for antibodies against flaviviruses were screened for west nile virus (wnv)-specific antibodies by blocking elisa and sele ... | 2007 | 17255248 |
| besnoitia darlingi infection in a virginia opossum (didelphis virginiana). | this is a case report of natural infection with besnoitia darlingi in a virginia opossum (didelphis virginiana) in louisiana. clinical pathologic data included a severe nonregenerative anemia, inflammatory leukogram, increased hepatocellular leakage enzymes, renal azotemia, hyperkalemia, hypoglycemia, hypoalbuminemia, and proteinuria. tissue cysts containing bradyzoites were found in the majority of organs, especially the skin, mucous membranes, kidneys, adrenals, lungs, and heart. images of the ... | 2009 | 19368269 |
| prevalence of antibodies to trypanosoma cruzi, toxoplasma gondii, encephalitozoon cuniculi, sarcocystis neurona, besnoitia darlingi, and neospora caninum in north american opossums, didelphis virginiana, from southern louisiana. | we examined the prevalence of antibodies to zoonotic protozoan parasites ( trypanosoma cruzi, toxoplasma gondii, and encephalitozoon cuniculi) and protozoans of veterinary importance ( neospora caninum, sarcocystis neurona, and besnoitia darlingi) in a population of north american opossums ( didelphis virginiana) from louisiana. samples from 30 opossums were collected as part of a survey for t. cruzi in louisiana. frozen sera from these 30 opossums were examined using an indirect immunofluoresce ... | 2010 | 21158620 |
| endogenous lipid pneumonia in opossums from louisiana. | endogenous lipid pneumonia was present in 19 of 27 opossums (didelphis virginiana) trapped in the vicinity of baton rouge, louisiana. the severity of lesions varied from small pleural and subpleural aggregates of foamy macrophages with minimal disruption of pulmonary architecture to large nodular accumulations of foam cells with cholesterol clefts and localized emphysema. the cause of the lipid pneumonia may be related to pulmonary nematode parasite infections, which were evident in 13 of the af ... | 2012 | 3373627 |
