Isolation of various Arcobacter species from domestic geese (Anser anser).
In this study, the prevalence and distribution of various Arcobacter spp. were investigated in samples taken from the cloacae of healthy domestic geese raised in Turkey. A membrane filtration technique with a non-selective blood agar was employed after enrichment in Arcobacter enrichment broth (AEB) to isolate a wide range of Arcobacter spp. In addition, the isolates were characterized phenotyp...
متن کاملJuvenile Greylag Geese (Anser anser) Discriminate between Individual Siblings
Social species that maintain individualised relationships with certain others despite continuous changes in age, reproductive status and dominance rank between group members ought to be capable of individual recognition. Tests of "true" individual recognition, where an individual recognises unique features of another, are rare, however. Often kinship and/or familiarity suffice to explain dyadic...
متن کاملStress assessment in captive greylag geese (Anser anser).
Chronic stress--or, more appropriately, "allostatic overload"--may be physiologically harmful and can cause death in the most severe cases. Animals in captivity are thought to be particularly vulnerable to allostatic overload due to artificial housing and group makeup. Here we attempted to determine if captive greylag geese (Anser anser), housed lifelong in captivity, showed elevated levels of ...
متن کاملKaryotype and C-banding pattern of the domestic geese Anser anser populations (Aves: Anatidae) in Egypt.
The karyotype and C-banding pattern of domestic Greylag geese Anser anser anser populations collected from five localities in El Minia, Egypt, that have either whitish grey or white feather color patterns were described. All populations have a diploid number of 2n= 80 chromosomes. Of the 80 chromosomes, 10 pairs, including ZW chromosomes, were macrochromosomes and the remaining 30 pairs were mi...
متن کاملSocial and environmental factors modulate leucocyte profiles in free-living Greylag geese (Anser anser)
BACKGROUND Blood parameters such as haematocrit or leucocyte counts are indicators of immune status and health, which can be affected, in a complex way, by exogenous as well as endogenous factors. Additionally, social context is known to be among the most potent stressors in group living individuals, therefore potentially influencing haematological parameters. However, with few exceptions, this...
