Keywords: Chryseobacterium indologenes, ventilator-associated pneumonia, newborn |
Chryseobacterium indologenes is a gram-negative, non-fermentative bacillus that causes opportunistic
infections, especially in the newborns and immunocompromised patients. This bacterium, which is resistant
to chlorination, creates a potential source of infection by contaminating respirators, intubation tubes and
humidifiers in the hospital. In the literature, there are studies reporting Chryseobacterium indologenes as
a causative agent of bacteremia, ventilator-associated pneumonia, meningitis, peritonitis, endocarditis,
pyelonephritis and lumboperitoneal shunt infection. Studies have reported that this bacterium was resistant
to antibiotics, such as carbapenems, cephalosporins and aminoglycosides. Also, the susceptibility rates of
trimethoprim sulfamethoxazole, ciprofloxacin and piperacillin tazobactam were also found to be high, and
it was emphasized that the most appropriate antibiotics for treatment may be the new quinolones, such
as levofloxacin and gatifloxacin. Levoloxacin is an antibiotic used in the treatment of ventilator-associated
pneumonia caused by multidrug-resistant microorganisms, as it reaches high concentrations in the lung tissue
and respiratory secretions. Although there are limited data about the use of levofloxacin in newborns, there
are studies that show clinical success when used in appropriate dose and duration. In this case report, C.
indologenes isolated as a causative agent of ventilator-associated pneumonia in a newborn with cerebral palsy
and its antibiotic resistance is presented.
