Escherichia coli is a microorganism that is found in the normal intestinal microbiota of humans and warm-blooded animals, causing intestinal or extra-intestinal infections. Many pathogenic E. coli strains can cause diarrhea, septicemia, neonatal meningitis, mastitis, urogenital system infections and various intra-abdominal, lung, soft tissue and skin infections in pets. Determining the genotypic and phenotypic characteristics of Escherichia coli strains isolated from animals is very important for the prevention of infections caused by E. coli. In recent years, a new animal pathotype mammary pathogenic E. coli (MPEC), which causes mammary gland infections in animals has been included in the extraintestinal pathogenic E. coli group. The fact that approximately %25-%35 of the use of antimicrobials in the treatment of Gram-negative agents is unsuccessful indicates that the use of correct diagnostic tools should take place in routine before etiological diagnosis. Profiles in bovine milk with mastitis suggest that clinical mastitis is associated with dysbacteriosis and that the microbial community in an intact mammary gland helps prevent intramammary infection. In this review, the change in bacterial diversity of milk microbiota due to antimicrobial use in E. coli-induced mastitis cases is discussed together with current studies.
