| surveillance potential of non-native hawaiian birds for detection of west nile virus. | west nile virus (wnv) was first detected in north america in 1999. alaska and hawaii (hi) remain the only u.s. states in which transmission of wnv has not been detected. dead bird surveillance has played an important role in the detection of the virus geographically, as well as temporally. in north america, corvids have played a major role in wnv surveillance; however, the only corvid in hi is the endangered hawaiian crow that exists only in captivity, thus precluding the use of this species for ... | 2015 | 26304918 |
| characterization of poxviruses from forest birds in hawaii. | two strains of avian pox viruses were isolated from cutaneous lesions in hawaiian crows (corvus hawaiiensis) examined in 1994 and a third from a biopsy obtained in 1992 from an infected bird of the apapane species (himatione sanguinea) by inoculation of the chorioallantoic membranes (cam) of developing chicken embryos. the resulting proliferative cam lesions contained eosinophilic cytoplasmic inclusion bodies characteristic of pox virus infection. the pathogenicity of these three viruses in dome ... | 2000 | 10813603 |
| 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 |
| characteristics of naturally acquired plasmodium relictum capistranoae infections in naive hawaiian crows (corvus hawaiiensis) in hawaii. | indigenous to hawaii, the hawaiian crow (corvus hawaiiensis) is the world's most severely endangered species with only 3 reproductively active pairs remaining in the wild. seven captive-reared, avian malaria-naive c. hawaiiensis were exposed in an outdoor aviary and hematologically and serologically monitored for 9 wk. three birds showed plasmodium relictum capistranoae parasitemia (6.35%, 2.15%, and 0.60%). all birds were seroconverted for malaria on week 7 as determined by enzyme-linked immuno ... | 1996 | 8627494 |
