Description ABSTRACT
newlineThe present study has been taken up, to assess Salmonella contamination in the
newlinecontent and shell of commercial layer hen eggs, non-commercial layer hen eggs,
newlineJapanese quail and duck eggs, collected from the retail outlets of Kottayam, Kerala.
newlineThe various Salmonella strains encountered in the present study has been subjected to
newlineserotyping to see the prevalence of various serotypes. Which revealed the presence of
newlineprevalence of serotype such as S. Worthington, S. Weltevreden, S. Typhimurium, S.
newlineBareilly, S. Dublin S. Enteritidis, S. Infantis were observed. Further, antibiotic
newlineresistance of the strains has been studied to find out the prevalence of multiple
newlineantibiotic resistance (MAR) among these strains. Drug resistance pattern of the
newlineisolates showed high degree of multiple antibiotic resistance among strains with
newlinevariety of different patterns indicating a large pool of resistance plasmids among
newlinethese organisms. The high degree of drug resistance among Salmonella strains from
newlinethe egg samples may be due to the sub therapeutic regimen of antibiotics in the
newlinecommercial poultry farming operations. The growth and survival of Salmonella in
newlinealbumen and yolk of eggs, heat resistance of S. Enteritidis in liquid whole eggs as well
newlineas in pasteurized liquid whole eggs and the thermal inactivation of S. Enteritidis in
newlineeggs subjected to cooking in water were also studied. Extract of four different spices
newlinesuch as garlic, ginger, onion and green chili were also tested for their antibacterial
newlineactivity against Salmonella in eggs from commercial layer hen eggs, non-commercial
newlinelayer hen eggs, Japanese quail and duck. The experimental studies were done using
newlineegg microcosm. In view of the above mentioned reasons it was considered worth
newlinewhile to undertake a study. Accordingly, the present study was planned and the result
newlineof the study was presented under the title Studies on Salmonella contamination
newlinein the eggs of layer hens, ducks, and Japanese Quail the work is presented
newlineunder five chapters.
