Study of Type of Bacteria That Found in Ear, Mouth, Nose of Second Stage Nursing Department Student

Abstract

The samples collected from 70 nursing student second stage ,the sample was mouth ,ear ,nose .The sample
cultured on nutrient agar ,MaCconkey agar ,Mannitol agar ,and brain heart agar. Observed different type of
bacteria on MaCconkey agar (lactose fermenting ,lactose non fermenting ,lactose slow fermenting ,Mucoid
shape ,and different type of bacteria on Mannitol Agar and nutrient agar .after that the isolate tested with
Gram stain , Catalase test and then Analytic profile index perform. The results showed the bacteria is (5 )
(0,5%)isolates of Staphylococcus aureus and (2)(0,2%) isolates of pseudomonas aeruginosa from 70 ear
samples , (5 )(0,64%)isolates Staphylococcus aureus and ( 4 )(0,51%)isolates of Staphylococcus epidermedis
from 70 mouth samples and 5(0,5%) isolates from pseudomonas aeruginosa ,(2)(0,2%) isolates of Serratia
marcescens from70 nose samples.And then the antibiotic sensitivity tested against :
Ciprofloxacin ,Gentamycin,Vancomycin,Pencilin,Azithromycin,Cefex,Amikacin,levofloxacin3 and the
result as in table below :
