This study was performed in the period February 2009 through January 2010 to determine the role of dairy cattle in transmitting listeriosis to in Beni-Suef Governorate, Egypt. Individual milk samples and rectal swabs were gathered from 175 dairy cows (125 clinically diseased and 50 apparently healthy). A total of 7S kariesh cheese and 150 dairy shop milk samples were randomly collected from the same localities where the examined cattle were reared. Stool and blood samples -we.e taken from 125 humans comprisiog 75 individuals residing in close contact with tbe examined COoNS and SO feverisb inpatients. Tbe occurrence of Listeria spp. in the. examined dairy cattle revealed that 1.14 % of individual.,milk samples barboured Listeria spp.; 1. innocua (0.57 %) and L. seeliiger; (0.57 %). None of rectal swabs revealed a positive result. 1. monocytogenes could not be recovered from any of tbe examined cattle samples. Examination of kariesh cbeese demonstrated a p6sitive result to L lnnocua (1.33 %). Concerning dairy sbop milk examined, 5.33 % was Listeria si,Jp.4posilive; tbey were identified as L monocytogenes (2.67 %), L. innocua (1.33 0/0) and L. seeligeri (1,33 %). Examination of bumans revealed a positive result for 1. welshimeri in a stool sample (0.8 %) taken from an apparently bealthy woman while all tbe examined blood samples Were Listeria-negative.
