| dc.description.abstract | Freshly prepared fruit juices sold by local market vendors in Dinajpur
city were analyzed for the bacteriological quality. Forty (40) fresh
fruit juices were collected from different areas around Dinajpur city.
Standard plate count techniques were followed to assess Total viable
bacterial count (TVC), Total coliform count (TCC), and Total
Staphylococcal count (TSC). The total viable bacterial count ranged
from 1.8×104 to 5.6×107cfu/ml. Total coliform count and Total
Staphylococcal count of juice samples were ranged from 1.36×103 to
5.76×106 cfu/ml and 0 to 5.85×106 cfu/ml respectively. The juice
samples were also found to be contaminated with Escherichia coli,
Staphylococcus spp., Salmonella spp. & Klebsiella spp. Out of 40
freshly prepared fruit juice samples collected, 38 samples (95%)
showed the presence of E. coli. The percentage of Staphylococcus
spp., Salmonella spp. & Klebsiella spp. of the tested samples were
75%, 12.5%, and 10% respectively. So the fruit juice samples were
unsafe for drinking. Antibiotic resistance pattern of the isolated
bacteria revealed that, among the four isolated bacteria E. coli,
Salmonella spp., Klebsiella spp. were 100% resistant to Ampicillin but
Staphylococcus spp. were 87% resistant to Ampicillin. Isolated
Klebsiella spp. was found to be 75% resistant to Amoxicillin and
Salmonella spp. were 20% resistant to Vancomycin. Such drug
resistance properties may render these pathogens cause serious
health hazards because of ineffective treatment of the sufferers by
the commonly prescribed antibiotics. It was concluded that due to
unhygienic fruit handling in the unsanitary environmental conditions
vi
the juices become contaminated with bacteria which are harmful for
public health.
