| prevalence of antibodies to toxoplasma gondii and trichinella spiralis in 509 pigs from 31 farms in oahu, hawaii. | serum samples from 509 pigs from 31 farms in oahu, hawaii were examined for antibodies to toxoplasma gondii using the agglutination test in dilutions of 1:25, 1:50, and 1:500 and for trichinella spiralis using the enzyme-linked immunosorbent assay. toxoplasma gondii antibodies were found in 48.5% of pigs. antibody titers were: 5.1% positive at 1:25 dilution, 28.6% positive at 1:50 dilution and 14.7% positive at 1:500 dilution. the prevalence of toxoplasma gondii antibodies in garbage-fed pigs (6 ... | 1992 | 1496803 |

| fatal toxoplasmosis in free-ranging endangered 'alala from hawaii. | the 'alala (corvus hawaiiensis) is the most endangered corvid in the world, and intensive efforts are being made to reintroduce it to its former native range in hawaii. we diagnosed toxoplasma gondii infection in five free-ranging 'alala. one 'alala, recaptured from the wild because it was underweight and depressed, was treated with diclazuril (10 mg/kg) orally for 10 days. antibodies were measured before and after treatment by the modified agglutination test (mat) using whole t. gondii tachyzoi ... | 2000 | 10813600 |
| toxoplasmosis in three species of native and introduced hawaiian birds. | toxoplasma gondii was found in endemic hawaiian birds, including 2 nene geese (nesochen sandvicensis), 1 red-footed booby (sula sula), and an introduced bird, the erckels francolin (francolinus erckelii). all 4 birds died of disseminated toxoplasmosis; the parasite was found in sections of many organs, and the diagnosis was confirmed by immunohistochemical staining with anti-t. gondii-specific polyclonal antibodies. this is the first report of toxoplasmosis in these species of birds. | 2002 | 12435157 |
| toxoplasmosis in a hawaiian monk seal (monachus schauinslandi). | toxoplasma gondii infection in marine mammals is intriguing and indicative of contamination of the ocean environment with oocysts. t. gondii was identified in a hawaiian monk seal (monachus schauinslandi) that had visceral and cerebral lesions. tachyzoites were found in the lymph nodes, spleen, diaphragm, heart, adrenal glands, and brain. a few tissue cysts were found in sections of the cerebrum. the diagnosis was confirmed serologically, by immunohistochemical staining with t. gondii-specific p ... | 2005 | 16108571 |
| [evaluation of toxoplasmosis seroprevalence among 2416 women of childbearing age followed at the pasteur institute of new caledonia]. | evaluation of toxoplasmosis seroprevalence was conducted in 2416 women of childbearing age by pasteur institute of new-caledonia. the estimated seroprevalence was 56.7%, significantly higher in the north-east part of the territory (79.1%), area characterized by strong precipitations, and in the melanesian ethnic group (62.1%). the habits of this population could enhance contamination by ingestion of oocysts during childhood or adolescence, particularly in the north-east territory. melanesian wom ... | 2004 | 17304750 |
| infectious disease monitoring of the endangered hawaiian monk seal. | as part of conservation efforts between 1997 and 2001, more than 25% (332 animals) of the endangered hawaiian monk seal (monachus schauinslandi) population was sampled in the northwestern hawaiian islands. serum samples were tested for antibodies to viruses, bacteria, and parasites known to cause morbidity and mortality in other marine mammal species. antibodies were found to phocine herpesvirus-1 by using an enzyme-linked immunosorbent assay, but seropositive results were not confirmed by virus ... | 2007 | 17495307 |
| evidence of feline immunodeficiency virus, feline leukemia virus, and toxoplasma gondii in feral cats on mauna kea, hawaii. | we determined prevalence to feline immunodeficiency virus (fiv) antibodies, feline leukemia virus (felv) antigen, and toxoplasma gondii antibodies in feral cats (felis catus) on mauna kea hawaii from april 2002 to may 2004. six of 68 (8.8%) and 11 of 68 (16.2%) cats were antibody positive to fiv and antigen positive for felv, respectively; 25 of 67 (37.3%) cats were seropositive to t. gondii. antibodies to felv and t. gondii occurred in all age and sex classes, but fiv occurred only in adult mal ... | 2007 | 17495320 |
