Question
A 37-week-old infant was delivered by cesarean section and discharged from a Connecticut hospital when he was ten days old. Two days later he was lethargic and had a fever. When he was readmitted to the hospital, he had multiple brain abscesses caused by Citrobacter diversus. After a prolonged illness, the baby died. A second infant with a normal pregnancy and delivery died of C. diversus meningitis after a short illness. Nine infants in the hospital nursery had umbilical cord colonization by C. diversus. Environmental cultures were negative for hospital equipment. What is the normal habitat of this gram-negative, facultatively anaerobic, non-endospore-forming, lactose-positive rod? Provide a plan for identifying the source of infection and preventing further infection.Explanation / Answer
Citrobacter diverses are mainly isolated from water, sewage, soils, and food, feces of man and can be found in urine, sputum, and other clinical specimens. They can sometimes be opportunistic pathogens particularly in immunocompromised patients in hospitals or in infants. for finding out the source of organism we need to collect sample from all individula and side by side all the sources used in deilvery room to be culture such as saline bottle food source water and the instrument used for operation in theaters. so the antibiogram of each isolates can be matched for similarity and molecular printing such RFLP and other trcik cam be sued to match them.
