  The anti-ulcer effect of betaine was evaluated in rat model of HCl-ethanol induced gastric ulcer. Oral administration of HCl-ethanol caused a significant increase in the number of lesions in the gastric mucosa, volume of gastric juice, acidity and decreased activity of the pepsin. An increased level of lipid peroxidation and diminished tissue antioxidant system was also observed. Pre oral treatment with betaine (250 mg/kg/day for 21 days) counteracted all these changes induced by HCl-ethanol and maintained the rats at near normalcy. The gastro protective potential was further confirmed by histopathological studies of the gastric mucosa. The anti-ulcerogenic activity of betaine might be ascribable to its ability to neutralize the hydrochloride secreted into the stomach and/or to its free radical scavenging activity which protects the gastric mucosa against oxidative damage by decreasing lipid peroxidation and strengthening the mucosal barrier.

  Enteric bacterial population associated with farmed freshwater prawn and its environment, water quality of prawn farm and the existing association between these parameters were studied. Microbiological parameters were determined following the United States Food and Drug Administration (USFDA) methods and the physico-chemical parameters as per the standard methods of American Public Health Association (APHA). Prawn samples yielded a mean Total Plant Count (TPC) in the range of 4.57 to 6.66 log cfu g-1 and was the highest among all other samples. Prawns followed by water samples had the higher level of enteric indicator organisms. Sediment showed higher count of sulphite reducing clostridia. Emerging pathogen E. coli O157:H7 were absent in all the samples analyzed. Enterobacter (31.5%) followed by Citrobacter (13.2%) and non enteric bacteria Aeromonas (11%) were the dominant flora recovered. Escherichia, Klebsiella, Hafnia, Serratia, Salmonella and Shigella were the other opportunistic enteric bacterial pathogens detected from this system. The rearing practices such as use of cow dung as fertilizer and microbiologically contaminated feed could have influenced the enteric flora. Study on various physico-chemical parameters of pond water revealed that they were within the suitable range for the freshwater prawn culture. Correlation analysis revealed a significant positive correlation between pollution indicator parameters such as Total Organic Carbon (TOC), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD) with that of Total Plate Count (TPC) and Total Enterobacteriaceae Count (TEC) of the pond water and prawn samples. Presence of bacteria of public health significance in the aquaculture pond envisages strict hygienic handling, processing of prawn from this system and cooking prior to consumption to ensure public health safety.

  A study was designed to investigate the enteric bacterial population associated with farmed freshwater fish and its environment, limnological quality of carp farm and the existing association between these parameters. Enteric indicator bacterial counts were determined following the United States Food and Drug Administration (USFDA) methods and the physico-chemical parameters according to the standard methods of American Public Health Association (APHA). Fish samples yielded mean microbiological counts in the range of 4.19 to 4.85 log CFU g-1, sediment in the range of 5.18±0.01 to 6.34±0.01 log CFU g-1, pond water in the range of 3.64±0.03 to 6.10±0.04 log CFU mL-1. Fish and feeder canal water showed higher count for all indicator bacterial count. Sediment showed 2 log cycle higher count of sulphite reducing clostridia. Emerging pathogen E. coli O157:H7 were absent in all the samples analyzed. Aeromonas (26.2%) followed by Enterobacter (24.6%) were the dominant flora recovered. Escherichia, Klebsiella, Serratia, Hafnia, Plesiomonas, Shigella, Salmonella, Morganella and Yersinia were the other opportunistic enteric bacterial pathogens detected from this system. The rearing practices such as natural fertilization and feeding could have influenced the enteric flora. Study on the various physico-chemical parameters of pond water revealed that they were within the suitable range for the freshwater fish culture throughout farming phase. Correlation analysis revealed a significant positive correlation between physico-chemical parameters such as total organic carbon (TOC), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD) with that of Total Plate Count (TPC), Total Enterobacteriaceae Count (TEC), Total Coliforms (TC), Faecal Coliforms (FC) and E. coli (EC). Presence of bacteria of public health significance in the aquaculture ponds envisages a strict hygienic handling and processing of fish from the culture systems for ensuring public health safety.
