Increased prevalence of indicator and pathogenic bacteria in Vembanadu Lake: a function of salt water regulator, along south west coast of India.

Increased Prevalence of Indicator and Pathogenic Bacteria in the Kumarakom Lake: A Function of Salt Water Regulator in Vembanadu Lake, A Ramsar Site, Along West Coast of India

Prevalence of indicator bacteria such as Escherichia coli and pathogenic bacteria like Vibrio Cholerae, Vibrio Parahaemolyticus and Salmonella were analysed in Vembanadu lake (9035'n 76025'e), along the west coast of India for a period of one year (October 20042005 September). Estuarine water samples were taken monthly from ten stations on the southern (inside bund region) and northern sides (o...

Potential public health significance of faecal contamination and multidrug-resistant Escherichia coli and Salmonella serotypes in a lake in India.

OBJECTIVE To assess the prevalence of faecal coliform bacteria and multiple drug resistance among Escherichia coli and Salmonella serotypes from Vembanadu Lake. STUDY DESIGN Systematic microbiological testing. METHODS Monthly collection of water samples were made from ten stations on the southern and northern parts of a salt water regulator constructed in Vembanadu Lake in order to prevent ...

An assessment of potential public health risk associated with the extended survival of indicator and pathogenic bacteria in freshwater lake sediments.

Microcosm studies were performed to evaluate the survival of Escherichia coli, Salmonella paratyphi and Vibrio parahaemolyticus in water and sediment collected from the freshwater region of Vembanad Lake (9'35 °N 76'25 °E) along the south west coast of India. All three test microorganisms showed significantly (p < 0.01) higher survival in sediment compared to overlying water. The survival in di...

Influence of river discharge on abundance and dissemination of heterotrophic, indicator and pathogenic bacteria along the East Coast of India.

In order to examine the influence of discharge from different rivers from peninsular India and urban sewage on intensity and dissemination of heterotrophic, indicator and pathogenic bacteria, a study was carried out during peak discharge period along coastal Bay of Bengal. The coastal Bay received freshwater inputs from the river Ganges while Godavari and Krishna contributed to the south. Contr...
