Cross-Sectional Study of Major Strains of Salmonella enterica Subspecies Enterica Serovar Typhi among Borehole Used in Uli Community

Abstract

Salmonella enterica subspecies enterica serovar Typhi; a dominant species found in borehole water, has been receiving drastic attention not only in causing human infections but also for its involvement in antibiotic resistance, of which 80% of these resistant genes are encoded in the plasmid. This study was undertaken to evaluate the cross-sectional study of enteric Salmonella species in borehole water used in Uli community. Samples were randomly collected from different boreholes from different locations in Uli community using standard microbiological techniques. The prevalence of the different strains encountered in the samples were also determined. The study revealed the presence of Salmonella enterica subspecies enterica serovar Typhi strain CMCST (STCM), Salmonella enterica subspecies enterica serovar Typhi strain WG51146 (STWG) and Salmonella enterica subspecies enterica serovar Typhi strain R192829 (STR1)of which 58.00% were positive to Salmonella ser. Typhi, and the occurrences of STCM, STR1 and STWG were 31.03 %, 24.14 % and 44.83 % respectively. From the above study, different strains of Salmonella enterica ser. Typhi were isolated from borehole water used at Uli community, of which isolate STWG was most predominant strain in the study samples.
