Descriptive herd-level data, frequency of CM (overall and pathogen-specific), and frequency of Strep. agalactiae isolates that were cryopreserved, re-cultured, and selected for genotyping assessment and antimicrobial susceptibility testing.

Descriptive herd-level data, frequency of CM (overall and pathogen-specific), and frequency of Strep. agalactiae isolates that were cryopreserved, re-cultured, and selected for genotyping assessment and antimicrobial susceptibility testing.本数据集涵盖描述性畜群水平数据、临床乳腺炎（CM）的发生频率（含总体发生情况与病原体特异性发生情况），以及经冷冻保存、重新培养后被选取用于基因分型鉴定与抗菌药物敏感性试验的无乳链球菌（Strep. agalactiae）分离株的发生频率。
