Title: A Study On The Nasal Carriage Of Staphylococci In Man In Khartoum State
Author: MIRGHANI, AMIRA
Abstract: The nasal carriage of staphylococci in diseased and healthy individuals was studied. The sensitivity of isolates to different antibacterial agents was determined to express the effect of hospitalization in acquiring drug resistance. Sixty nasal swabs were collected, 50 samples from patients (spent different periods in the hospital) and 10 samples fromhealthy individuals. Isolation was achieved on Baird-Parker medium. The isolated staphylococci from patients included Staph. aureus(20, 33.3%), Staph. auricularis(2, 3.3%),Staph. caprae(1, 1.7%), Staph. caseolyticus(4, 6.7%),Staph. chromogens(10, 16.7%), Staph. epidermidis (5, 8.3%), Staph. gallinarium(1, 1.7%), Staph. haemolyticus(3, 5%), Staph.hyicus (5, 8.3%), Staph. kloosii(2, 3.3%), Staph. lentus(2, 3.3%), Staph. lugdunensis(1, 1.7%), Staph. sciuri (2, 3.3%), Staph. saprophyticus(1, 1.7%), Staph. schleiferi(1, 1.7%). The isolated staphylococci from healthy individuals included Staph aureus(3, 30%), Staph. epidermidis (3, 30%), Staph .hyicus(1, 10%), Staph. intermiduis(2, 20%), Staph. lugdunensis(1, 10%). The antibiotic sensitivity patterns of isolates recovered from patients showed the gradual development of resistance as the patients spent more time in the hospital. Staphylococci isolated from normal individuals showed lower degree of resistance to the tested antibacterial agents. It was concluded that many staphylococci including S. aureus colonize the nasal cavity of patients and begin to acquire resistance against different antibacterial agents with time in the hospital.
