CULTURE SENSITIVITY PATTERNS OF BACTERIA ASSOCIATED WITH RESPIRA TORY ILLNESS IN HUMAN

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.
