| antimicrobial resistant salmonella spp. isolated from double-crested cormorants (phalacrocorax auritus) and common loons (gavia immer) in florida. | antimicrobial resistant salmonella spp. were found in double-crested cormorants and common loons in florida. single or multiple resistance occurred in all salmonella agona isolates from cormorants, primarily to ampicillin, sulfonamids, streptomycin, neomycin, and kanamycin. similar patterns of resistance were found in s. agona isolates from common loons. in addition, isolates of s. saint paul from loons were found resistant to tetracycline and streptomycin, while 2 of 7 isolates of s. infantis w ... | 1979 | 384026 |
| 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 |
| wintering of neurotropic velogenic newcastle disease virus and west nile virus in double-crested cormorants (phalacrocorax auritus) from the florida keys. | during november 2002, six double-crested cormorants (dccs; phalacrocorax auritus) were found moribund in big pine key, fl, exhibiting clinical signs indicative of neurologic disease. postmortem diagnostic evaluations were performed on two adult birds. virulent newcastle disease virus (ndv) was isolated from a cloacal swab from cormorant 1. west nile virus (wnv) was isolated from the brain and lung of cormorant 2. nucleotide sequence analysis of a portion of the fusion (f) protein gene of the ndv ... | 2005 | 16094838 |
| brevetoxicosis in seabirds naturally exposed to karenia brevis blooms along the central west coast of florida. | harmful algal bloom events caused by the dinoflagellate karenia brevis occurred along the central west florida, usa, coast from february 2005 through december 2005 and from august 2006 through december 2006. during these events, from 4 february 2005 through 28 november 2006, live, debilitated seabirds admitted for rehabilitation showed clinical signs that included disorientation, inability to stand, ataxia, and seizures. testing of blood, biologic fluids, and tissues for brevetoxin by enzyme-lin ... | 2013 | 23568900 |
| genetic characterization of members of the genus contracaecum (nematoda: anisakidae) from fish-eating birds from west-central florida, usa, with evidence of new species. | specimens of contracaecum spp. from phalacrocorax auritus and pelecanus occidentalis from florida were characterized by sequencing of the small subunit of the mitochondrial ribosomal rna gene (rrns) and by pcr-based rflp analysis of the same gene and of the internal transcribed spacers (its) of nuclear ribosomal dna. analyses of the rrns sequence data using the mp and upgma approaches yielded trees with similar topologies, delineating 3 main clusters. specimens from ph. auritus, morphologically ... | 2007 | 17352849 |
| clinicopathologic features of suspected brevetoxicosis in double-crested cormorants (phalacrocorax auritus) along the florida gulf coast. | outbreaks of morbidity and mortality in double-crested cormorants (phalacrocorax auritus) along florida's gulf coast have occurred sporadically for at least 30 yr. during these outbreaks, the clinic for the rehabilitation of wildlife, located on sanibel island in florida, has admitted a substantial number of cormorants with consistent presentation of primarily neurologic clinical signs. in order to investigate the association of these outbreaks in cormorants with exposure to brevetoxin, we compa ... | 2002 | 12216798 |
