| antibodies to human influenzavirus neuraminidase (the a-asian-57 h2n2 strain) in sera from australian pelagic birds. | sera collected from australian pelagic birds specifically inhibited the neuraminidase of the asian/57 (h2n2) strain of human influenzavirus. neuraminidase inhibition titres of some sera were high and the avidity of the inhibitor was comparable to that of specific antibody. the neuraminidase of a/hong kong/1/68 (h3n2), which has undergone considerable antigenic drift in man since 1957, was inhibited to a lesser extent by the bird sera, while the neuraminidases of the a/bel/42 (h0n1) and a/fm/1/47 ... | 1972 | 4541008 |
| status of breeding seabirds on the northern islands of the red sea, saudi arabia. | we undertook breeding surveys between 2010 and 2011 to assess the status of breeding birds on 16 islands in the northern saudi arabia. sixteen bird species were found breeding at three different seasons; i.e. winter (osprey), spring (caspian and saunder's terns), and summer (lesser crested, white-cheeked, bridled terns). it is postulated that food availability is an important factor influencing the breeding of seabirds in the northern saudi arabian red sea. several species laid eggs earlier in n ... | 2014 | 24955009 |
| developing a bioindicator in the northwestern persian gulf, iran: trace elements in bird eggs and in coastal sediments. | levels of arsenic (as), cadmium (cd), cobalt (co), lead (pb), nickel (ni), selenium (se), and vanadium (v) were evaluated in coastal sediments, egg contents, and eggshells of crab plover (dromas ardeola), bridled tern (sterna anaethetus), lesser crested tern (s. bengalensis), and western reef heron (egretta gularis) breeding in the northwestern persian gulf. levels of cd, pb, ni, v, and se were greater in eggs of terns than in eggs of crab plover, perhaps due to the higher trophic level of terns ... | 2015 | 25330737 |
| risk to breeding success of waterbirds by contaminants in hong kong: evidence from trace elements in eggs. | concentrations of 17 trace elements (as, se, rb, sr, ag, sb, cs, tl, pb, v, cr, mn, co, cu, zn, cd, and hg) were determined in eggs of little egrets (egretta garzetta), black-crowned night herons (nycticorax nycticorax) and bridled terns (sterna anaethetus) from northwestern and northeastern coastal areas of hong kong. results indicated significant differences among the three species. eggs of little egrets and black-crowned night herons appeared to be good bioindicators for monitoring selected e ... | 2005 | 15749545 |
| implications of foraging and interspecies interactions of birds for carriage of escherichia coli strains resistant to critically important antimicrobials. | globally, gulls have been associated with carriage of high levels of escherichia coli strains resistant to critically important antimicrobials (cias), a major concern, as these antimicrobials are the sole alternative or one among only a few alternatives available to treat severe life-threatening infections in humans. previous studies of australian silver gulls demonstrated high levels of resistance to cias, particularly fluoroquinolone and extended-spectrum cephalosporins, among e. coli strains ... | 2020 | 32801178 |
| lead, mercury, and cadmium in feathers of tropical terns in puerto rico and australia. | levels of lead, cadmium, and mercury were examined in breast feathers of terns nesting on offshore islets near culebra, puerto rico and on michaelmas cay and heron island on the great barrier reef, australia. levels of all metals in these tropical terns were predicted to be lower than those of terns nesting in temperate regions, because the tropical species feed offshore of non-industrial areas where contamination should be less than for temperature-nesting species that feed in inshore estuaries ... | 1991 | 1958083 |
