Prevalence of antimicrobial resistance among bacterial pathogens isolated from bovine mastitis in northern Jordan

Over the past decade a number of studies have been published on the prevalence of antibiotic resistance among bovine mastitis pathogens. So far, no similar studies have been performed in Jordan or neighboring countries. A pilot study, on emergence of antibiotics resistance among bovine mastitis pathogens, was carried out in the Veterinary Health Center (VHC) in Jordan University of Science and Technology. Records reviews were carried out on 205 mastitis cases between the years of 2002-2006. Culture and sensitivity tests were done. The most prevalent pathogens isolated were Staphylococcus aureus (S. aureus) (53.4%), E. coli (16 %), Streptococcus non-agalactiea (Strep non-ag) (5.9%), and coagulase negative Staphylococci (CNS)(5.9%). The antibiotics for which, most of the isolated pathogens were sensitive to were enrofloxacin (61.2%) and ciprofloxacin (58.7%). While the ones that the pathogens were mostly resistant against were sulfa/trimethoprim (87.4%), and penicillin (84.5%). Apparently, you can notice the risk of an emergence of an antimicrobial resistance among mastitis bacterial pathogens in Jordan.
