Rapid Point-of-Care Detection of Pathogens for Lower Respiratory Tract Infections in ICU Patients
Published on: September 19, 2026
[Forty-seven cases of lower respiratory tract infections due to E. ictaluri]
1Department of Respiratory Diseases, Xuan Wu Hospital, Capital University of Medical Sciences, Beijing 100053.
Objective:
To study the risk factors and treatment of lower respiratory tract infections due to E. ictaluri, and the cause of its improved detection by sputum culture in recent years.
Methods:
To sum up the number of positive cultures and analyze the clinical features of the cases with positive sputum culture tested from 1959 to 1998.
Results:
Before 1996, there were no positive cultures (0%) in 17,500 sputum samples using manual techniques, in 1997 and 1998 the aggregate positive rate was 2.3% (47/1,962), using SCEPTOR detecting instrument. On chi square testing of the two results derived from the two methods, P < 0.001. On drug sensitivity testing, E. ictaluri was sensitive to imipenem, cefotaxime and tobramycin.
Conclusions:
E. ictaluri is an uncommon opportunistic pathogen of lower respiratory tract infections. Lowered body resistance is a risk factor, and improved technology is the principal cause for detection of E. ictaluri infections.
