Ovine (n=140) and caprine (n=35) raw bulk tank milk samples from farms in central Greece were examined for the occurrence of enterotoxigenic Staphylococcus aureus. The S. aureus isolates were screened for staphylococcal enterotoxin (SE) production, the presence of enterotoxin genes, antibiotic resistance (AR), and methicillin resistance. S. aureus was isolated from 24.3% and 31.4% of ovine and caprine milk samples, respectively. Among the S. aureus isolates of ovine milk (n=34) and caprine (n=11) milk, the enterotoxigenic (SEA-SED) isolates were 21 (61.8%) and 7 (63.6%) for the ovine and caprine milk, respectively. Most toxigenic isolates harbored more than one toxin gene and a total of 11 distinct toxinotypes were detected. The most frequent toxin-gene combinations were "sec, tst" (8 isolates), "seb, seg, sei, tst" (4), "seb, seg, sei" (3), and "seb" (3). Six isolates displayed multiple AR towards up to five antimicrobials. Among ovine milk isolates, the highest resistance frequency was observed towards erythromycin (11.8% of the isolates) and tetracycline (8.8%). Among caprine milk isolates, the most frequent resistance was observed towards erythromycin (18.2%). One methicillin-resistant S. aureus (MRSA) isolate was detected in an ovine milk sample and belonged to spa type t4038. This spa type

“…Moreover, they may develop multi-antimicrobial resistance (Normand et al, 2000;Blahová et al, 2004;Authier et al, 2006). In recent years, much has been written about the emergence of methicillin-resistant S. aureus and methicillin-resistant coagulase-negative staphylococci (Normanno et al, 2007;Leonard and Markey, 2008;Springer et al, 2009;Weese, 2010;Huber et al, 2011).…”

This study was conducted during a six months period (March to August 2008) at the Veterinary laboratory, Department of Animal Resources, Doha, Qatar to determine the incidence of different bacterial genera farm animals in particular the occurrence of Staphylococcus species. The samples were from the rectum, milk, feces, nasal, swab of vagina, cloacal -uterin, intestine, liver and pus. Samples were collected from various animals of different regions. A total 318 of 429 samples gave positive results for Gram-negative and Gram-positive bacteria and 90 cultures were identified as Staphylococcus. The highest isolates were from camels' milk and none were obtained from specimens of cats and horses. A total of 33 selected Staphylococcus isolates were identified to species level and the most common isolated was coagulase-positive S. aureus (14), followed by coagulase-negative, S. lentus (10), S. xylosus (5), S. sciuri (2), S. lugdunensis (1) and S. caprae (1). The antimicrobial susceptibility profiles of these were determined using cephalothin, gentamycin, neomycin, ampicillin, norfloxacin, penicillin, tetracycline and a combination of trimethoprim and sulphamethoxazole. All identified species were sensitive to cephalothin except one strain of S. aureus. Most of the isolates showed multiple antimicrobial resistance profiles.

“…The development of resistance both in human and animal bacterial pathogens has been associated with the extensive therapeutic use of antimicrobials or with their administration as growth promoters in food animal production (Normanno et al 2007). Antibiotics have been extremely useful for the treatment of infectious diseases in the last 50 years and have become indispensable for the treatment of many diseases formerly known as lethal (Pesavento et al 2007).…”

Yurdakul N.E., Erginkaya Z., Ünal E. (2013): Antibiotic resistance of enterococci, coagulase negative staphylococci and Staphylococcus aureus isolated from chicken meat. Czech J. Food Sci., 31: 14-19.We determined the antibiotic resistance of enterococci, coagulase negative staphylococci, and Staphylococcus aureus isolated from chicken meat samples. The antibiotic resistance of the isolated strains was estimated by the KirbyBauer disk diffusion method (according to the NCCLS document M2-A9 suggestions). It was found that all strains of Enterococcus spp. were resistant to tetracycline, 75% of them were resistant to ciprofloxacin, and 50% of them were resistant to erythromycin, vancomycin, and chloramphenicol. Also all strains of S. aureus were resistant to tetracycline and 25% of S. aureus strains were resistant to erythromycin and chloramphenicol, whereas all strains of S. aureus were sensitive to teicoplanin and 25% of them were sensitive to vancomycin and ciprofloxacin. As for the isolate of coagulase negative staphylococci (CNS), 68.1% of them were resistant to erythromycin, 77.2% of them were resistant to tetracycline, 59% of them were resistant to vancomycin, 9% of them were resistant to teicoplanin, and 27.2% of them were resistant to both chloramphenicol and ciprofloxacin. As a result, it was found that most of the strains (all of S. aureus and Enterococcus spp., also 77.2% CNS) were resistant to tetracycline.
