#Listeriosis in pregnancy
1. Febrile gastroenteritis
2. Bacteremia
3. CNS infection uncommon
Most common in 3rd trimester
Listeria can cross placental barrier —> fetal death, premature birth, infected newborn
Granulomatosis infantiseptica

#Listeriosis is a foodborne disease caused by L. monocytogenes bacteria. After ingestion via contaminated food, it can cause severe, life-threatening disease, often manifested as #septicaemia and/or #meningitis.
The severe disease happens particularly among elderly & immunocompromised people. It also may result in complications related to pregnancy.

#Listeria aerobic facultative anaerobic beta-hemolytic, non–spore-forming, short gram-positive rod tumbling motility. single or in short chains. On Gram stain, Listeria may resemble Pneumococci (diplococci), Enterococci, Diphtheroids or be gram variable/confused w/ Haemophilus sp
when a positive blood or CSF culture is preliminarily identified as Diphtheroids, the clinician should consider the possibility that the isolate represents #Listeria
