ABSTRACT

A total of 60 milk samples collected from different milk vendors of different areas of the
Faizabad district were subjected to different microbial counts and antibiotic sensitivity of bacterial
isolates. Range (Mean ± SE) of different microbial counts viz., coliform, E. coli, faecal streptococci,
Staphylococcus aureus, yeast and mould, and total viable counts were found as 0.00 - 4.50 (3.00
± 1.15), 0.00 - 1.20 (0.70 ± 0.46), 1.00 - 2.80 (1.80 ± 0.64), 0.00 - 3.00 (2.10 ± 1.14), 0.00 -
2.40 (1.00 ± 0.78), and 3.80 - 7.20 (5.50 ± 0.99) log10 cfu/ml, respectively. On the basis of
different microbial counts viz., coliform, E. coli, faecal streptococci, Staphylococcus aureus,
yeast and mould, and total viable count, the milk samples of rejected category were found as
58.33%, 50%, 51.67%, 56.67%, 41.60%, and 53.33%, respectively. E. coli; Salmonella spp.;
Klebsiella pneumoniae; Proteus ammoniae; Campylobacter jejuni; Staphylococcus aureus and
Bacillus cereus isolated in this study showed highest sensitivity against norfloxacin and ofloxacin
(93.33% each); amikacin, ciprofloxacin, gentamicin and chloramphenicol (100% each); ofloxacin
(100%); gentamicin (100%); ofloxacin (75%); enrofloxacin (91.43%) and amikacin (100%),
respectively. Moreover, some isolates of E. coli, Salmonella spp. and Campylobacter jejuni showed
multiple resistance against some antibiotics.
