Abstract:
This study was designed to identify and determine in-vitro antibiotics sensitivity patterns of bacteria associated
with respiratory illness of human. A total of 60 throat swab samples were aseptically collected from 3 age
groups of 1-20 years (young), 21-40 years (adult) and 41-60 years (old). Isolated bacteria then subjected to
determine their in-vitro antibiotic sensitivity patterns. From this study, it was observed that bacterial flora
present in the throat swab of human with their percentage of distribution were Staphylococcus spp. (40.54%) of
which Coagulase positive Staphylococcus (32.43%) and Coagulase negative Staphylococcus (8.11 %), Klebsiella
spp. (24.325%), Pseudomonas spp. (18.92%), E. coli (8.11 %) and Bacillus spp. (8.11 %). Percentages of isolated
bacteria in different age groups were 29.73% in young, 40.54% in adult and 29.73% in old. Among the isolates
Coagulase positive Staphylococcus, Klebsiella and Pseudomonas were the predominant species. Percentages of
Coagulase positive Staphylococcus spp. were high in age groups of 21-40 years (21.62%) whereas Klebsiella
spp. were the predominant species of age groups of 1-20 years (10.81%) and 41-60 years (8.11%).
Pseudomonas spp were the predominant species (8.11%) in age groups of 41-60 years. The isolated Coagulase
positive Staphylococcus spp and Klebsiella spp were resistant 10 amoxicillin and ampicillin but sensitive to
ciprofloxacin, enrofloxacin and norfloxacin. Isolated Pseudomonas spp. showed resistant properties against
amoxicillin, ampicillin petloxacin, gentamycin and furazolidone but sensitive to ciprofloxacin and nortloxacin.
