How is Citrobacter transmitted?

MODE OF TRANSMISSION: Citrobacter may be spread by direct contact with hospital staff members, mother to child transmission or through ingestion of environmental sources (fecal-oral route) but person-to-person transmission is more prevalent 7, 11.

What is Citrobacter in urine?

[1,2] The genus Citrobacter is distinct group of aerobic, gram negative bacilli from the Enterobacteriaceae family, widely distributed in water, soil, food and intestinal tract of man and animals. UTIs caused by Citrobacter species have been described in 5 to 12% of bacterial urine isolates in adults.

How did Citrobacter get?

Citrobacter are found in a variety of environmental sources, including soil and water, and in the human intestines. They are rarely the primary source of illness, though some strains can cause infections of the urinary tract, sepsis, and infant meningitis.
