Antimicrobial resistance is a significant public health threat and a major challenge for treatment of companion animal skin infections. Antimicrobial susceptibility testing (AST) is a critical tool which clinicians should employ when a patient may need antimicrobials beyond those deemed "first-tier." Clinicians may have noted that many more isolates of Staphylococcus sp. and Pseudomonas aeruginosa appear more resistant which likely reflects both the emergence of acquired antimicrobial resistance, but also changes to clinical definitions which are outlined in this article.

Background: Group B streptococcus (GBS) causes neonatal invasive disease, mainly sepsis and meningitis. Understanding the clinical characteristics, laboratory tests, and antibiotic resistance patterns of GBS invasive infections provides reliable epidemiological data for preventing and treating GBS infections.

Methods: Clinical characteristics and laboratory test results from 86 patients with neonatal invasive disease (45 cases of early-onset disease [EOD] and 41 cases of late-onset disease [LOD]) recruited from Fujian Maternity and Child Health Hospital between January 2012 and December 2021 were analyzed.
