Multiresistant and especially Methicillin-Resistant Staphylococcus aureus (MRSA) poses a serious public health problem that requires their immediate identifcation and antibiotic resistance characteristics. In order to determine antibiotic resistance S. aureus poultry and bovine origin, 8840 samples were collected from slaughterhouses in the northern region of Algeria between years 2009 and 2014. 8375 samples were from an avian origin (1875 from laying hens and 6500 from broiler chickens) and the rest was from bovine origin. Bacteriological isolation and identifcation were made by classical culture method and antibiotic resistance patterns were determined by disc difusion test. Te prevalence of S. aureus was 42% in laying hens, 12% in broilers, and 55% in bovine samples. Te prevalence of MRSA was 57%, 50%, and 31% in laying hens, broiler chickens, and bovine, respectively. While MRSA strains isolated from poultry showed cross-resistance to aminoglycosides, fuoroquinolones, macrolides, sulphonamides, and cyclins, those isolated from bovine also revealed similar multiresistance except for sulphonamide. Tis high percentage of methicillin resistance and multidrug resistance in S. aureus poultry and bovine origin may have importance for human health and curing of human infections. 1. Introduction Antibiotic resistance is prevalent in all parts of the world. Antibiotic resistance developed by bacteria is an increasingly serious threat to global public health that requires imme- diate actions [1]. Methicillin-resistant Staphylococcus aureus (MRSA) is a well-known pathogen of human and animals most commonly isolated from clinical cases [2]. MRSA was frst identifed in England in 1961 afer which it emerged worldwide [3]. It was reported that MRSA clone ST80- IV, an epidemic community-acquired Methicillin-Resistant Staphylococcus aureus (C-MRSA), is widespread in the Algiers hospital and community settings [4]. Nasal carriage of multiresistant Staphylococci and MRSA in calves was detected and emphasized that they can be a cause of severe disease in humans [5]. In another study, antibiotic resistance Staphylococci isolated from poultry in the 1970s and 2006 was reported. Carriage of MRSA in healthy poultry was reported and emphasized that antibiotic resistance was higher in the recent isolates than prior isolates [6]. A high percentage of methicillin resistance in Staphylococci isolated from bovine mastitis was also reported in Algeria [7]. Tis study aimed to determine the occurrence of MRSA from laying hens, broilers, and bovine and their antibiotic resistance.
