E. Coli

Review of Literature
Osman (1992) collected 150 random, samples from different
broiler farms at Sharkia Government she found that 45 stains were
positive for salmonella species with an incidence of 30%. Serological
typing of the isolated salmonella species revealing 21 (46.7%) were S.
pullorum, 9 (20%) were S.gallinarum, 7 (15.6%) were S.typhimurium
and 8/17 were not identified.
Draz et al. (1996) examined 60 water and 45 litter samples from
poultry environment and farms. Salmonella species was isolated with
the frequency of 1.7% (1/60) and 2.2% (1/45) respectively. The
isolated water borne strain was identified as S. typhimurium.
Rusul et al. (1996) estimated the prevalence of salmonella
species among broilers retailed at wet markets and processing plants
in Malaysia. A total of 158 out of 445 (35.5%) and 52 out of 104
(50%) broiler carcasses obtained from wet markets and processing
plants were contaminated with Salmonella species respectively.
Salmonella species was isolated from 14 out of 98 (14.3%) samples of
intestinal content. Litter sample from broiler and breeder farms were
positive for Salmonella species with the frequency of 8/40 (20%) and
2/10 (20%), respectively. Examined breeder, broilers and layers
flocks, Salmonella species were recovered from litter sample (42%),
water in drinking troughs (36%), feed left over in feed trays (28%),
water in the main tanks (17%), cloacal swabs (13%) and stock feed
(8%).
