“…Despite the economic importance associated with mastitis, it is not thoroughly investigated in Nigeria (Ameh et al, 1999;Junaidu et al, 2011). Staphylococcus aureus is a major bacterium implicated with contagious bovine mastitis (Suleiman et al, 2013), that is difficult to prevent and control in the affected farms. Therefore, identification of S. aureus from mastitic milk is necessary for the control and prevention of this disease.…”

“…are the most typical contagious organisms causing mastitis (Suleiman et al, 2013; http://dx.doi.org/10.4314/bajopas.v10i1.38 while the environmental organisms are streptococci, Enterobacteriaceae and coagulase-negative staphylococci (CONS) (Bradley 2002;Barkema et al, 2009). Other organisms such as Pseudomonas spp., Pasteurellaceae, some pyogenic and anaerobic bacteria, yeasts and algae are also implicated in some cases of mastitis Economic losses involving mastitis are mainly decrease in milk production, increased culling rate, cost involved with veterinary care and to a larger extent poor milk quality (Seegers et al, 2003;Rahman et al, 2009;Hashemi et al, 2011).…”

“…Although oxacillin resistance is rare in S. aureus strains, some of them could be resistant to methicillin or oxacillin and lack the gene coding for antibiotic resistance (12). The inconsistency in the frequency and extent of antimicrobial resistance reported by studies in Iran and rest of the world (15,(17)(18)(19)(20)(21) could be due to different of the techniques used, geographic area, and type of samples collected and common antibiotics prescribed during a particular period of time. High level of contamination in raw milk could have several reasons including cross-contamination caused by preparation by hand and failure to comply with code of hygienic practices for the milking process.…”

Background and Objective: Antibiotic-resistant Staphylococcus aureus strains have become a problem in treatment of infections caused by S. aureus. This study aimed to evaluate antibiotic resistance in S. aureus isolates from raw milk and detect femA gene in these isolates, as a confirmatory test for identification of S. aureus species.Methods: This cross-sectional study was performed on 110 raw milk samples. After culture in Cooked Meat broth, presence of S. aureus in grown colonies was confirmed in accordance with Iranian National Standard, No. 1194. Antibiotic resistance was then evaluated according to guidelines recommenced by the Clinical Laboratory Standards Institute. FemA-specific polymerase chain reaction was performed on antibiotic-resistant strains using specific primers and standard strains to differentiate S. aureus from other species.Results: S. aureus were found in 43 (39.09%) of the 110 collected samples. Among these isolates, 79.07% and 76.75% were phenotypically resistant to penicillin and ceftazidime, respectively. In addition, the femA gene was detected in all isolates. Conclusion:The results of this study show a high prevalence of resistance to penicillin and ceftazidime among S. aureus strains isolated from raw milk.

Staphylococcus aureus is an opportunistic Gram positive pathogen and the causative agent of many human and animal diseases. It is also an important human foodborne pathogen. Certain strains of S. aureus can produce staphylococcal enterotoxins (SEs) in foods and cause staphylococcal food poisonings (SFP). In recent years S. aureus has been increasingly associated with antibiotic resistance. Methicillin-resistant S. aureus (MRSA) includes those strains that have acquired genes conferring resistance to methicillin and essentially all other beta lactamantibiotics. MRSA was initially reported as a nosocomial pathogen in human hospitals (or hospital-associated MRSA, HA-MRSA). Since the 1990s, community-acquired or community-associated MRSA (CA-MRSA) infections have also been reported to affect people having no epidemiological connection with hospitals. More recently, MRSA has been isolated from most food-producing animals and foods of animal origin, raising public health concerns. MRSA strains have been isolated from cows’ or small ruminants’ milk and various dairy products in many countries. The MRSA prevalence in milk and dairy products recorded in different countries or even regions of the same country differs significantly.High MRSA prevalence have been recorded in milk produced in most African countries, for instance as high as 60.3% in Ethiopia. The MRSA prevalence in Asian countries varies from high e.g. 28.3% in Iran to low (e.g. in Korea and Japan). In most European countries, the MRSA prevalence in milk and dairy products has been generally found to be low. In the US and Canada, zero to low MRSA prevalence estimates have been reported. The investigation of MRSA prevalence in milk may serve as a tool for assessing both the sanitary conditions employed in dairyherds and the health risks that humans may encounter when infected with antibiotic-resistant strains.
