WATER QUALITY ASSESSMENT AND THE PREVALENCE OF ANTIBIOTICRESISTANT BACTERIA FROM A RECREATIONAL RIVER IN KUCHING, SARAWAK, MALAYSIA

Recreational activities may affect a river’s water quality, which may pose health risks to those in direct contact with the water. This study aims to analyse the water quality if Jangoi River in Kuching, Sarawak, by measuring the conventional chemical and biological parameters and to characterise th...

This study aims to analyse the water quality if Jangoi River in Kuching, Sarawak, by measuring the conventional chemical and biological parameters and to characterise the bacteria isolated from the water based on their antibiotic susceptibility. The determination of the water quality is based on the Department of Environment’s Malaysian Water Quality Index (WQI), which was carried out at three sampling stations (upstream, middle stream and downstream) in two different sampling trips. Six water quality parameters were measured: Dissolved oxygen, biological oxygen demand, pH, chemical oxygen demand (COD), ammoniacal nitrogen and total suspended solid. The WQI values of the river ranged from 88% to 92%, classifying the river under Class I. The one-way ANOVA analysis revealed that the parameter values for all the three stations are not significantly different, except for the COD. The higher COD value of the upstream water could be due to the release of wastewater from houses and agricultural activities near Jangoi River. The faecal coliform and total coliform counts ranged from 650 CFU/100 mL to 1,000 CFU/100 mL and 20,050 CFU/100 mL to 23,250 CFU/100 mL, respectively.Nine bacteria were isolated and 16S rRNA PCR and DNA sequencing. The DNA sequencing revealed the presence of Escherichia coli, Chromobactium violaceum, Lelliota amnigena,Pseudomonas aeruginosa, Achromobacter xylosoxidans, Stenotrophomonas maltophilia, Pseudomonas hibiscicola, Achromobacter mucicolens and Bacillus pacificus. Antibiotic susceptibility tests demonstrated the highest percentage of susceptibility for ciprofloxacin (100%), followed by ampicillin (40%) and chloramphenicol (40%).
