Abstract
Hiochermcal and serological charactenzation to
isolated bacteria was encountered.
This study included 90 poultry carcasses, products and
environmental samples {( 10 environmental samples, 3l\ poultry meat
samples and 42 poultry products sample which included ( 11 liver, 19
luncheon , 9 gizzard , 3 heart samples )} were collected from different
markets at Cairo and Menoufia Governorates. The samples were
transported in ice tank to laboratory as soon as possible and culture on
selective media. The isolated bacteria were identified by growth
characters, motility, and biochemical reaction and serotyping using
specific antisera.
Results of investigation revealed that Salmonella species were
detected in environmental samples (utensils, water), poultry carcasses
and poultry products (gizzard, liver, luncheon and heart) at a
percentage of 10%, 2.6% and 2.3% respectively. Out of these positive
salmonella isolates (66.6%) strains were belonged to Salmonella
enteritidis and 33.3%. strains were belonged to S. typhimurium.
The results of isolation of different bacteria from poultry
products indicate that Proteus vulgaris and P. mirabilis were the most
isolated species from poultry products with a percentage of (14.3% for
each ) followed by Serratia marcescens , Staphylococcus aureus , Morganella morganii . E coli . Shigella dysenteriae and S. enteritidis

Results of bacteria isolated from local luncheon samples
indicated that the most prevalent species were Proteus vulgaris,
Serratia marcescens, Enterobacter aerogenes, Pseudomonas
aeruginosa, Enterococcus faecalis and Klehsielfa pneumoniae (11.1 ~/o
for each) , followed by Proteus inirabilis, Proteus morganii , Serratia
liquefaciens , E. coli , S. aureus and Shigella dysentery with a
percentage of 5.5% each. Meanwhile, results of bacteria isolated from
liver samples revealed that Proteus mirabilis was the most prevalent
species (33.3%) followed by Serratia marcescens and Enterobacter
aerogenes with the percentage of (20% each ) while Serratia
liquefaciens, E coli. S aureus and Klebsiella pneumoniae were
isolated with a percentage of 6.6 %for each.
Results of bacteria isolated from gizzard samples showed that
Proteus vulgaris was the most prevalent one (30%) followed by P.
morganii (20%) while S. enteritidis, S. aureus. Shigella dysenteriae,
Enterococcus faecalis, Pneumococci were isolated with a percentage of
10% each. Results of bacteria isolated from heart samples it was found
that Pseudomonas aeruginosa , S. aureus and P. vulgaris were isolated
with a percentage of333% for each.
Concerning environmental samples (water -utensils and poultry
processing plant), results revealed that 10 environmental samples of
water and utensils in processing plant harbouring bacteria with a total
number of 9 isolates. Shigella dysentenae. Enterobacter hafniae, S.
