Lesteriosis in animal By Mariam Magdy Abdel Motaleb Salma N. el yamany

Is an infection but not * contagious disease. (life_threating disease)* *it is called circling disease. *Also winter_spring disease of feedlot or haused ruminant. defination 26/10/2015 Pm lecture

1/ 2/ 3/ 4/ 5/ Listeria monocytogenes bacteria 1/ it is a gram positive 2/ extremely antibiotic resistant coccoid to bacillus shaped bacteria found in environment 3/ live in soil,in poorly made silage & spoiled forages & DI tract & mammary GI 4/ found in feces of infected birds, wild mammals fish,insects& fetal feces ( meconium) 5/ shedded in nasal discharge, uterine discharge, aborted fetus 26/10/2015 Pm lecture

Listeriosis is most prevalent during spring & winter months, w` suggests prevalance of l. monocytogenes thus management practice can be applied to minimize the risk of infection 26/10/2015 Pm lecture

* Common in domestic animal ( domestic mammals & poultry) espacially adult ruminant w` are feed contaminated silage than human beings * Newly born, elder ages & pregnant. 26/10/2015 Pm lecture

 1) through ingestion of contaminated feed or water or by fecal shedding of bacteria (( oral _fecal route )) 2) through inhalation **Infected animal could die if improperly treated **Zoonosis cosumption of contaminated unpasteurised milk by human can lead to meningitis & meningoencephalitis if pregnant, abortion N.B 26/10/2015 Pm lecture
