Antimicrobial resistance and mastitis classification of pathogens in small ruminant mastitis

Abstract

Mastitis is an important disease of small ruminants (SR) that results in substantial morbidity, mortality, and economic losses from treatment or loss of product. There is currently little in­formation on SR mastitis pathogens or antimicrobial sensitivity in U.S. populations. This study 1) identifies breed, age, produc­tion use and stage of lactation of SR diagnosed with mastitis at a veterinary teaching hospital (VTH); 2) characterizes bacterial species and antimicrobial sensitivity in SR mastitis; and 3) clas­sifies SR mastitis into peracute, acute, subclinical and chronic, and correlates with bacterial isolates.
