| toxoplasmosis in a california sea lion (zalophus californianus). | disseminated toxoplasmosis was diagnosed in a female california sea lion that had been used in thermoregulation studies for about 4 years while housed in a small enclosure with a fresh-water pool at the university of hawaii, honolulu. toxoplasma gondii was demonstrated in and around necrotic lesions of the heart and the stomach. source of the infection was not established; however, studies on toxoplasmosis in cats were being conducted at the institution, and common caretakers attended both group ... | 1977 | 835862 |
| 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 |
| 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 |
| toxoplasma gondii antibody prevalence and two new genotypes of the parasite in endangered hawaiian geese (nene: branta sandvicensis). | toxoplasma gondii is a protozoan parasite transmitted by domestic cats ( felis catus ) that has historically caused mortality in native hawaiian birds. to estimate how widespread exposure to the parasite is in nene (hawaiian geese, branta sandvicensis), we did a serologic survey for t. gondii antibody and genetically characterized parasite dna from the tissues of dead birds that had confirmed infections by immunohistochemistry. of 94 geese sampled, prevalence on the island of kauai, maui, and mo ... | 2016 | 26967138 |
| mortality patterns in endangered hawaiian geese (nene; branta sandvicensis). | understanding causes of death can aid management and recovery of endangered bird populations. toward those ends, we systematically examined 300 carcasses of endangered hawaiian geese (nene; branta sandvicensis) from hawaii, maui, molokai, and kauai between 1992 and 2013. the most common cause of death was emaciation, followed by trauma (vehicular strikes and predation), and infectious/inflammatory diseases of which toxoplasmosis (infection with toxoplasma gondii) predominated. toxicoses were les ... | 2015 | 26161721 |
| toxoplasma gondii isolates from mouflon sheep (ovis ammon) from hawaii, usa. | little is known of toxoplasma gondii isolates circulating in wildlife. the mouflon (ovis ammon) is very popular game animal, hunted for its trophy horns. here, we report the isolation and genetic characterization of t. gondii from two mouflons from hawaii, usa. both sheep had antibodies titers of 1:800 or higher. viable t. gondii were isolated and nested pcr-rflp genotyping revealed two genotypes, a clonal type iii (designated tgmouflonus1), and a new genotype (designated tgmouflonus2, and toxod ... | 2015 | 25066494 |
