| large scale mortality of nestling ardeids caused by nematode infection. | during the summer of 1976, an epornitic of verminous peritonitis caused by eustrongylides ignotus resulted in large scale mortality of young herons and egrets on pea patch island, delaware. mortality was highest (84%) in snowy egret nestlings ( egretta thula ) and less severe in great egrets ( casmerodius albus ), louisiana herons ( hydranassa tricolor ), little blue herons ( florida caerulea ), and black crowned night herons ( nycticorax nycticorax ). most deaths occured within the first 4 week ... | 1977 | 24228957 |
| pathogenesis of eustrongylides ignotus (nematoda: dioctophymatoidea) in ciconiiformes. | natural (n = 157) and experimental (n = 5) infections with the nematode eustrongylides ignotus are described for ciconiforms collected in florida (usa). larvae perforated the ventriculus in 3 to 5 hr and caused hemorrhage and bacterial peritonitis that sometimes progressed to a fibrous peritonitis with extensive adhesions. severity of the disease was related inversely to the age of the bird and directly to the number of parasites involved. some infections in adult birds were resolved. as a conse ... | 1993 | 8487374 |
| the epizootiology of eustrongylidosis in wading birds (ciconiiformes) in florida. | a total of 2,167 individuals representing 15 species of wading birds was examined for infection with the nematode eustrongylides ignotus in florida (usa). ten of the species were infected with the greatest prevalences occurring in great blue herons (ardea herodius) (33%), great egrets (casmerodius albus) (22%), and snowy egrets (egretta thula) (19%). among nestlings, prevalences increased with age. this parasite was estimated to cause at least 80% mortality among nestling ciconiiforms at one col ... | 1993 | 8487373 |
