Drug Resistance and Conjugative R Plasmids in Escherichia Coli Strains Isolated From Migratory Waterfowl

Abstract

We evaluated drug resistance and R plasmids of 554 strains of Escherichla coll isolated from feces of migratory waterfowl, including whistling swans (Cygnus columblanus), pintails (Anas acuta) and black-tailed gulls (Larus crassirostris)

Retrospective and Longitudinal Study of Salmonellosis in Captive Wildlife in Trinidad

“…The regulations governing the presence of antibiotics in meat and milk in Trinidad and Tobago is not presently enforced (Adesiyun et al, 1998c). Transfer of resistance factor among enterobacteriaceae is well documented (Marsik et al, 1975;Tsubokura et al, 1995).…”

Antibiotic-Resistant Escherichia coli Bacteria, Including Strains with Genes Encoding the Extended-Spectrum Beta-Lactamase and QnrS, in Waterbirds on the Baltic Sea Coast of Poland

“…Studies of resistant E. coli isolates have been mostly based on phenotype characterization of these isolates (20, 24, 26, 51, 58, 71,75,76,82), and the genes determining resistance to oldgeneration antibiotics were sporadically detected (17,21,22,29). Isolates of E. coli from birds on the Polish coast of the Baltic Sea were commonly resistant to old-generation antibiotics, and they were highly variable in phenotype and genotype characteristics.…”

“…In particular, bird populations sympatric to areas inhabited by people and areas with a high density of livestock were colonized with antibiotic-resistant E. coli strains possibly selected by the antibiotic practice in humans and domestic animals. Antibiotic-resistant E. coli isolates have been found in corvids (Corvus corone, C. frugilegus, C. macrorhynchos, Pica pica, and Pyrrhocorax pyrrhocorax) (3,46,48,53,74), house sparrows (Passer domesticus) (22,61), house martins (Delichon urbica) (73), feral pigeons (Columba livia forma domestica) (68), ducks, geese, and swans (Anas platyrhynchos, Anas acuta, Branta canadensis, and Cygnus columbianus) (17,26,51,82), cormorants (Phalacrocorax auritus and P. cristatus) (20,71), Egyptian vultures (Neophron percnopterus) (2), and, most frequently, in various gull species throughout the world (Larus argentatus, L. atricilla, L. audouinii, L. cachinans, L. crassirostris, L. glaucoides, L. hyperboreus, L. marinus, L. ridibundus, and L. vagae) (4,7,21,23,29,66,71,76,82). Corvids and gulls feeding on garbage dumps and in urbanized areas are frequently colonized with resistant strains of E. coli, and they are considered to be important reservoirs and vectors of these isolates in the environment (23,46).…”

Antimicrobial Susceptibility of <i>Escherichia coli</i> Isolated from Feces of Wild Cranes Migrating to Kagoshima, Japan

“…Tsubokura et al [19] reported that whistling swans harbored multi-antimicrobial-resistant E. coli at a higher rate (80%) than pintail (22%) and black-tailed gulls (46%) among migratory waterfowl in Japan. Thus, the distribution of resistant bacteria in wild animals varies according to the geographic location and animal species [8,17].…”
