Note: + = Positive, - = Negative[7] L. Ivanovii conony characteristics are observed on nutrient agar plates or slants.

Listeria ivanovii can be distinguished from L. monocytogenes and other Listeria species by culturing it on sheep or horse blood agar, which will produce a wide, clear or double zone of haemolysis, producing a so-called positive Christie-Atkins-Munch-Petersen (CAMP) reaction with Rhodococcus equi but not with haemolytic Staphylococcus aureus.

[8] L. ivanovii's unique feature compared to most species in this genus is that it can ferment D-ribose.

[10] Infection with L. ivanovii can lead to septicemic disease with enteritis, neonatal sepsis and even abortion.

[1] Although L. ivanovii is most typically found in sheep, it can be passed to humans via food such as fresh cheese.

[13] The best way to avoid this infection, especially for those at risk (elderly, weakened immune systems, and pregnant women) maintain a clean kitchen and to avoid foods such as unpasteurized milk, cheese made from unpasteurized milk, and raw fish.

L. ivanovii was identified, thus characterizing the species as an enteric opportunistic human pathogen.

Antibiotics effective against Listeria species include ampicillin, vancomycin, ciprofloxacin and azithromycin.
