Abortion listeriosis

Ingestion ofL. monocytogenes can cause abortion in humans and animals and in the case of listeriosis a prime characteristic is an increase in monocytes. 

Listeria monocytogenes, a bacterium that, when transmitted to humans, causes listeriosis. Listeriosis is characterized by flu-like symptoms, but can cause swelling of the brain and induce abortions. 

Zoonotic diseases are those transmitted from animals to humans, with a wide range of manifestations in humans from simple illness to death. Some of these are of special concern to pregnant women. Toxoplasmosis and listeriosis can cause, among other things, spontaneous abortions. 

Listeria A genus of rod-shaped aerobic motile Gram-positive bacteria. Only one species, L. monocytogenes, causes disease (listeriosis). It is resistant to physical and chemical treatments and can occur as a contaminant in certain foods, in faeces, etc. Listeriosis can take various forms, depending on the site of infection localization in the central nervous system causes meningo-encephaUtis, while uterine infection can result in abortion or congenital handicap in the fetus. 

Low dry matter silages contaminated with soil may also contain Listeria monocytogenes, a bacterium known to be responsible for several diseases such as meningoencephalitis, anterior uveitis, and placentitis and subsequent abortion in cattle. A number of fatalities in ruminant animals (mainly sheep) on silage diets have been confirmed as listerioses. Listeriosis in horses is uncommon, probably because silage is rarely given to horses.
