Resume of Ph.D. Work

In the Ph.D programme I had studied various aspects of Salmonella

contamination in fish and crustaceans such as their prevalence, antibiotic resistance

pattern and survival strategies in natural waters such as fresh water and sea water.

More than 1000 samples were analysed for the prevalence of Salmonella. Confirmed

strains were serotyped at National Salmonella and Escherichia Centre, Central

Research Institute, Kasauli, Himachal Pradesh, India. All the serotypes were subjected

to antibiotic sensitivity sensing in order to find out the level of resistance acquired by

them and multiple antibiotic resistance (MAR) indexing in order to assess the risk

associated with these strains. Important strains were tested for their survival strategies

in natural waters such as fresh water and sea water. The ability of the predominant

serotypes to adjust to the changes in salinity and temperature were also studied using

microcosms. The major findings were as follows:

Fourteen percentage of fishes and 17 percentage of crustaceans were

contaminated with Salmonella.

Serotyping revealed the presence of Salmonella weltevreden, S. mgulani, S.

typhi, S. typhimurium, and S. senftenberg.

S. senftenberg was encountered in only crustaceans while the other serotypes

were encountered in both fishes and crustaceans.

Antibiotic sensitivity testing revealed high degree of multiple antibiotic

resistance among the strains.

Multiple antibiotic reisistance (MAR) indexing of the strains showed that all

the strains were originated from high risk sources of contamination such as

human, poultry and dairy cattle, where antibiotics are often used.

Survival studies using microcosms of freshwater and seawter was carried out

to find out the role of various physico-chemical and biological parameters in

the self-purificationof natural waters when contaminated with Salmonella. The

results revealed biological factors such as predatioin, antibiosis, competition

and protozoan bacteriovory were the most important factors in neutralising the

Salmonella contaminants in natural waters. Physical factors such as uv and

visible light exerted only a secondary effect, while the chemical composition

of natural waters did not exert much negative impact.

Experiments to reveal the ability of selected strains of Salmonella to tolerate

changes in salinity and temperature showed that they are well suited to

estuarine conditions.

The findings of Ph.D were published in leading international journals

such as Food Microbiology (Academic Press Ltd., UK) and Letters in Applied

Microbiology (Society for Applied Bacteriology, UK).

During Ph.D I had also done considerable works on the bacterium

Escherichia coli and the finding were published in international journals of repute

such as World Journal of Microbiology and Biotechnology (Rapid Communication of

Oxford Ltd. UK) and Zentralblatt fur Hygiene und Umweltzmedizin (Gustav Fisher

Verlag, Stuttgart and New York).
