primary feather follicle ablation in common pintails (anas acuta acuta) and a white-faced whistling duck (dendrocygna viduata).eight 1-yr-old common pintails (anas acuta acuta) and one 2-yr-old white-faced whistling duck (dendrocygna viduata) were presented for the persistence of primary flight feathers 1 yr after pinioning. the birds were housed outdoors in an open enclosure necessitating flight prevention. the birds were placed under general anesthesia, and a diode laser was used to ablate the primary feather follicles of the previously pinioned wing. swelling was the most common side effect seen in seven out of nine ...201222779239
[helminth fauna anseriformes (aves) in the lodz zoological garden].in the years 1959-1990 429 birds on 30 species of anseriformes were examined post mortem at zoo lódź. the helminths were found in 108 birds (25.17%) of 19 species. in infected birds there were found 4 species of trematodes: one of them, catatropis verrucosa is in poland new for cygnus olor; 9 species of cestodes--7 of them are in poland new for examined hosts; namely: drepanidotaenia lanceolata for dendrocygna viduata, cygnus atratus, branta bernicla, and anas platyrhynchos; microsomacanthus par ...19979424942
cryptococcus neoformans var neoformans isolated from droppings of captive birds in nigeria.the yeast, cryptococcus neoformans, was found in apparently healthy birds at the jos wildlife park and zoo in jos, nigeria. cryptococcus neoformans var neoformans was isolated from feces of four captive bird species. five isolates belonged to serotype a while two were serotype d. serotype a of c. neoformans was isolated from a white face duck (dendrocygna viduata), eagle owl (bubo africanus cinerascene) and peacock (pavo cristatus). the other two (serotype d), were isolated from a spotted eagle ...19979131573
lead gunshot pellet ingestion and tissue lead levels in wild ducks from argentine hunting hotspots.lead poisoning in waterfowl due to ingestion of lead pellets is a long recognized worldwide problem but poorly studied in south america, particularly in argentinean wetlands where duck hunting with lead gunshot is extensive. in 2008, we found high pellet ingestion rates in a small sample of hunted ducks. to expand our knowledge on the extent of lead exposure and to assess health risks from spent shot intake, during 2011 and 2012 we sampled 415 hunter-killed ducks and 96 live-trapped ducks. we de ...201424314629
spm-1-producing pseudomonas aeruginosa st277 clone recovered from microbiota of migratory birds.the production of são paulo metallo-β-lactamase (spm-1) is the most common carbapenem resistance mechanism detected among multidrug-resistant pseudomonas aeruginosa clinical isolates in brazil. dissemination of spm-1-producing p. aeruginosa has been restricted to the nosocomial settings, with sporadic reports of environmental isolates due to contamination by hospital sewage. herein, we described the detection and molecular characterization of spm-1-producing p. aeruginosa recovered from the micr ...201729224710
whole angiosperms wolffia columbiana disperse by gut passage through wildfowl in south america.for the first time to our knowledge, we demonstrate that whole angiosperm individuals can survive gut passage through birds, and that this occurs in the field. floating plants of the genus wolffia are the smallest of all flowering plants. fresh droppings of white-faced whistling duck dendrocygna viduata ( n = 49) and coscoroba swan coscoroba coscoroba ( n = 22) were collected from brazilian wetlands. intact wolffia columbiana were recovered from 16% of d. viduata and 32% of coscoroba samples (to ...201830958251
serological evidence of west nile and usutu viruses circulation in domestic and wild birds in wetlands of mali and madagascar in 2008.the geographical distribution and impact on animal and human health of both west nile and usutu viruses, two flaviviruses of the japanese encephalitis complex, have been increasing during the past two decades. both viruses circulate in europe and africa within a natural cycle between wild birds and mosquitoes, mainly from the culex genus. we retrospectively analyzed sera from domestic and wild birds sampled in 2008 in two wetlands, namely the inner niger delta, mali, and the lake alaotra area, m ...202032197367
isolation of mycobacterium avium serotype 3 from a white-headed tree duck (dendrocygna viduata).tuberculous lesions were observed at necropsy in the liver of 1 of 10 white-headed tree ducks (dendrocygna viduata) imported from nigeria. microscopic examination revealed granulomas with acid-fast bacilli; mycobacterium avium serotype 3 was isolated. two chickens inoculated intraperitoneally with the isolant had gross and microscopic granulomas in the liver at necropsy 62 days after inoculation. isolants from chickens were serologically similar to the strain isolated from the duck.1976962763
