Survival of Salmonella Typhimurium and Salmonella Seftenberg in Solid Fraction of Slurry from Pig Farm Wastewater Treatment Plant Amended with Zeolite

چکیده
This study deals with influence of 1vol% and 2 vol% zeolites to survival of Salmonella typhimurium, S. seftenberg and indicator bacteria (psychrophilic, mesophilic, coliform and faecal coliform) in the solid fraction of pig slurry from agricultural wastewater treatment plant. PVC bottles with openings served as test carriers. In solid fraction with 1 vol% zeolites S. typhimurium survived for 9 days and S. seftenberg for 12 days. In solid fraction with 2 vol% zeolites S. typhimurium survived for 6 days and S. seftenberg for 9 days. In the control samples (solid fraction without zeolites) S. typhimurium survived 28 days and S. seftenberg 40 days. The present study demonstrated that addition of 1 vol% and 2 vol% zeolites have good desinfecting effect.

Prevalence of Salmonella enterica on a Danish pig farm presenting recurrent infections was investigated. A comparison of the pulsed-field gel electrophoresis patterns of fecal isolates from piggeries, waste slurry, and agricultural soil amended with Salmonella-contaminated animal waste (slurry) and subclinical isolates from the same farm (collected in 1996 and later) showed identical patterns, ...

The survival of Salmonella sp. in pig slurry submitted to treatment in a stabilization ponds system from a pig breeding farm in southern Brazil were evaluated. The stabilization ponds system proved to be efficient, reducing 93% of the Salmonella sp. population present in the slurry. The resistance pattern of 161 Salmonella Typhimurium strains isolated throughout the system were evaluated agains...

The effect of cattle manure and slurry application on percolation and survival of Escherichia coli O157:H7 and Salmonella enterica serovar Typhimurium was investigated for different soil depths after the addition of water. Four treatments were chosen for the first set of experiments: (i) addition of inoculated farmyard manure on the soil surface, (ii) mixing of inoculated farmyard manure with t...

The clonal relationship among Salmonella enterica serotype Typhimurium isolates from selected pig production units in Denmark was investigated by the pulsed field gel electrophoresis (PFGE) typing method to determine environmental survival and spread of Salmonella in different herds. Thirty-four Typhimurium isolated during 1996^1998 from porcine faeces and environmental samples from three pig f...
