MICROBIAL DIVERSITY AND ANTIBIOTICS RESISTANT PATTERN IN RURAL WATER SOURCE
Abstract
Water is a critical resource for daily life's existence, sustenance, and continuance. It j :
used in various domestic activities such as drinking, bathing, cooking, and industria]
processes. Although water is a universally important solvent, its role in disease
transmission has been reported. This study was aimed at analyzing the microbial
diversity and antibiotics resistant pattern in a rural water source. A total of 2 water
samples were collected in a sterile plastic containers, 5 from borehole water selected
through random sampling and 1 from boreholes from different streets and location in
Obudu Local Government Area in Cross River State and cultured using nutrient agar.
From this study shows that water sample 2 Ranch road Obudu had the highest bacteria
count ranged from 14.8x10° CFU/ml and water sample Ogoja road with 13.5x105
CFU/ml, while the total coliform count ranged 3.7x10° in sample 2 and 3.3x10° in
sample 1. The contamination rate and percentage distribution accessed on the water
samples revealed that among the water isolates Pectobacterium is the most frequently
occurring isolate, with a percentage occurrence of 4(33.3%). The Percentage
occurrence of Antibiotic resistance in bacterial isolate from the water sample revealed
that Cefuroxime, (CRX) Ceftriaxone (CTR) and Cefotaxime (CTX) had the highest
resistant rate of 12(120.0%). The antibiogram profile of bacterial isolates shows that
Citrobacter spp had the highest number of multi antibiotic resistance to Tetracycline
(TET), Chloramphenicol (CHL), Meropenem (MEM), Cefoperazone (CPZ), and
Gentamicin (GEN). Therefore, this present research work reveals that the Obudu
borehole water is highly contaminated. The consumption of water containing these
drug-resistant bacteria may lead to prolonged treatment for waterborne diseases, as the
standard antibiotics used may no longer be effective
