Antibiotic susceptibility testing of bacteria in drinking water sources in Akungba‐Akoko, Ondo State, Nigeria

Abstract

In present investigation, the bacteriological analysis and antibiotic sensitivity

pattern of drinking water samples collected from different sources of

Akungba

â€ÂAkoko, Nigeria was done. The antibiotics mainly considered in our

study for determining the sensitivity were amongst the commonly used in

this area for treatment of infectious diseases. As a result, the bacteriological

index, especially coliform count was observed notably high with 72 x10

1 cfu/

ml for stream sample and 26.4 x 10

1 cfu/ml for borehole sample. The major

bacterial isolates identified in the water samples were

Staphylococcus sp,

E.coli

â€Ânegative bacteria were

observed showing 75% and 65% resistant to Septrin and Amoxicillin respectively.

Also, multiple drug resistance was observed for many antibiotics.

Therefore, the presence of high amount antibiotic resistant bacteria of clinical

importance is reported in these water sources which are usually consumed

by students and members of the University community. Hence, this

study necessitates the need for water treatment so that epidemics of waterborne

bacterial disease can be averted in this region.

, Klebsiella sp, Pseudomonas sp., Enterococcus sp., Bacillus cereus and

others. With regards to the antibiotic sensitivity test, all isolates showed

100% resistance to Ampicillin and Cloxacillin and 85.7% resistance to Zinnacef

[a cephalosporin product]. However, the gram
