Identification of L. monocytogenes and atypical isolates by MALDI TOF MS.

The data represent the results of research within the scientific activity Miniatura 5 entitled "Characterization of atypical Listeria monocytogenes strains isolated from the food production environment financed by the National Science Center (no. DEC 2021/05/X/NZ9/00143). The aim of this part of the project was (i) to determine the peptide composition using the MALDI - TOF MS method and to create a database of profiles of reference L. monocytogenes strains (ii) to compare the protein composition profiles of atypical isolates to reference ones.
This dataset contains:
- Reports generated from the MALDI TOF MS instrument
 - Spectra of atypical L. monocytogenes isolates - spectra of reference L. monocytogenes strains
 - Peptide profiles of reference and atypical L. monocytogenes isolates.
 All necessary information regarding the above data and the type of instructions for viewing them are included in the README.docx file.

本数据集为科研活动"Miniatura 5"的研究成果，该活动的研究主题为"食品生产环境分离的非典型单核细胞增生李斯特菌（Listeria monocytogenes）菌株表征"，由国家科学中心（National Science Center）资助，项目编号为DEC 2021/05/X/NZ9/00143。
本项目此部分的研究目标为：(i) 采用基质辅助激光解吸电离飞行时间质谱（MALDI-TOF MS）方法测定肽组分，并构建单核细胞增生李斯特菌参考菌株的谱型数据库；(ii) 对比非典型分离菌株与参考菌株的蛋白质组成谱型。
本数据集包含以下内容：
- 基质辅助激光解吸电离飞行时间质谱（MALDI-TOF MS）仪器生成的检测报告
- 非典型单核细胞增生李斯特菌分离菌株的质谱图，以及单核细胞增生李斯特菌参考菌株的质谱图
- 参考菌株与非典型单核细胞增生李斯特菌分离菌株的肽谱图。
上述所有数据的相关说明以及查看操作指南均收录于README.docx文件中。
