Evaluation of the double-zone hemolysis (DZH) test for the detection of livestock-associated methicillin-resistant <i>Staphylococcus aureus</i>

This study evaluated a simple and reliable phenotypic test that can be very useful in the clinical microbiology laboratory to detect livestock-associated (LA) methicillin-resistant <i>Staphylococcus aureus</i> (MRSA) isolates and <i>S. aureus</i> of potential animal origin. The proposed double-zone hemolysis test has shown high positive and negative predictive values, sensitivity, and specificity to detect these LA-MRSA clones and <i>S. aureus</i> of potential animal origin. Most LA-MRSA clones exhibit resistance to different classes of antibiotics, with unique epidemiological characteristics, and their early detection has public health relevance and patient management.

Abstract

This study evaluated a simple and reliable phenotypic test that can be very useful in the clinical microbiology laboratory to detect livestock-associated (LA) methicillin-resistant <i>Staphylococcus aureus</i> (MRSA) isolates and <i>S. aureus</i> of potential animal origin. The proposed double-zone hemolysis test has shown high positive and negative predictive values, sensitivity, and specificity to detect these LA-MRSA clones and <i>S. aureus</i> of potential animal origin. Most LA-MRSA clones exhibit resistance to different classes of antibiotics, with unique epidemiological characteristics, and their early detection has public health relevance and patient management.
