Abstract
The occurrence of Salmonella in (1770) poultry was assessed from July
2010 through July 2011. The samples included the paper-lined boxes of
imported day-old broiler chicks (n=900), breeder chicks (n=300),
grandparent chicks (n=330), ducklings (n=150), and turkey poults
(n=90).Imported ducklings, and turkey poults were mostly Salmonlla
free. Although 16.7% of the imported broiler chicks were positive for
Salmonella, the imported breeders and grandparent chicks exhibited 10%
and 9.1% respectively. The most prevalent serotype isolated from broiler
chicks was S.enteritidis, imported from Turkey, Jordan, France, England,
and Saudi Arabia in all seasons of year. Serotype isolated from breeder
chicks was S.amherstana, imported from France in spring season.
S.enteritidis was isolated from grandparent chicks and imported from
England in winter season. Senteritidis is sensitive to phosphomycin with
tylosin, ciprofloxacin; colistin sulphate and oxytetracycline. On other
hand (240) imported birds was assessed for E.coli. The samples included
the internal organs of imported day-old broiler chicks (n=90), breeder
chicks (n=30), grandparent chicks (n=30), ducklings (n=60), and turkey
poults (n=30).The prevalence rate were 23.3%,20%,13.4%,46.7%
and13.3% respectively .The most prevalent serotype isolated from broiler
chicks were O91,O26,O11,O158, O44, O114, O125 and O145, imported
from Turkey, Jordan, Saudi Arabia, Poland and Serbia during all seasons
of year. The most prevalent serotype isolated from breeder chicks were
O91, O26, O11, O145, O114 and O124 imported from Ireland, France
and Holland during summer, winter and spring seasons.O91, O26
andO145 serotypes isolated from grandparent chicks during winter and
spring seasons imported from France, Germany and USA.
Concerning ducklings; the most prevalent serotype isolated were O91,
O26, O124 and O145, imported from France during summer, autumn and
winter seasons. Regarding turkey poults, isolated serotypes were O91,
O127, O124, O145, O114 and O64, imported from France, Germany,
Ireland and Poland during all seasons of year. E.coli is sensitive to
phosphomycin with tylosin, ciprofloxacin and colistin sulphate.
