| newcastle disease virus in double-crested cormorants in alabama, florida, and mississippi. | in order to understand the epidemiology of newcastle disease (nd) outbreaks in double-crested cormorants (phalacrocorax auritus), a study was conducted on wintering migratory cormorants (p. a. auritus) in alabama and mississippi (usa) and non-migratory cormorants (p. a. floridanus) that breed in florida (usa). antibodies against nd virus were detected by the hemagglutination-inhibition method in sera from 86 of 183 (47%) migratory cormorants over-wintering in eight roosting sites in alabama and ... | 2001 | 11763745 |
| defeating diplostomoid dangers in usa catfish aquaculture. | diplostomoid digenean metacercariae have caused widescale mortalities of channel catfish, ictalurus punctatus (rafinesque), at aquaculture farms in louisiana, mississippi and arkansas, usa. originally, based on a tentative diagnosis, the industry considered the primary harmful agent to be an introduced species from europe, bolbophorus confusus (krause, 1914), frequently reported from the american white pelican, pelecanus erythrorhynchos gmelin. our group has now shown, using its 1-2 plus three m ... | 2004 | 15357393 |
| morphologic and molecular identifications of digenetic trematodes in double-crested cormorants (phalacrocorax auritus) from the mississippi delta, usa. | increasing numbers of double-crested cormorants (phalacrocorax auritus) in the mississippi river delta, usa, have been observed over the past few decades. this piscivorous bird is a definitive host for numerous digenetic trematodes, some of which may cause pathology in a fish host. we conducted a 2-yr survey of intestinal trematodes in 35 double-crested cormorants collected in the mississippi delta. we counted gastrointestinal trematodes, identified them to species using morphometric and molecul ... | 2014 | 24171572 |
| prevalence of avian paramyxovirus 1 and avian influenza virus in double-crested cormorants (phalacrocorax auritus) in eastern north america. | although it is well established that wild birds, such as cormorants, carry virulent avian paramyxovirus serotype 1 (apmv-1; causative agent of newcastle disease) and avian influenza virus (aiv), the prevalence of these viruses among double-crested cormorants (phalacrocorax auritus) in the great lakes region of north america has not been rigorously studied. we determined the prevalences of apmv-1 and aiv in double-crested cormorants from the interior population of eastern north america. from 2009 ... | 2013 | 24502724 |
| the influence of geographical location, host maturity and sex on intestinal helminth communities of the double-crested cormorant phalacrocorax auritus from the eastern united states. | here the intestinal helminth infracommunities of 218 double-crested cormorants (phalacrocorax auritus) from 11 locations in alabama, minnesota, mississippi and vermont are documented. trematode infections were present in 98% of hosts; 65% of cormorants carried cestode infections, 4% were infected with acanthocephalans and 66% had nematode intestinal parasites. parasite infracommunities of hosts collected on wintering grounds had higher richness and diversity than did birds collected on breeding ... | 2016 | 27677375 |
| characterization of the life cycle of a fish eye fluke, austrodiplostomum ostrowskiae (digenea: diplostomidae), with notes on two other diplostomids infecting biomphalaria havanensis (mollusca: planorbidae) from catfish aquaculture ponds in mississippi, usa. | ocular diplostomiasis is caused by trematode species in the family diplostomidae, specifically those in the genera austrodiplostomum, diplostomum, and tylodelphys. diplostomid trematodes are globally distributed parasites of fish. heavy infections of diplostomids that parasitize the eyes of fish can result in acute mortality while chronic infections are often characterized by impaired vision or blindness. in the southeastern united states, commercial catfish production is threatened by piscivoro ... | 2016 | 26741049 |
