A total of 297 individuals of indoor Mus musculus Linnaeus, 1758 were trapped in two villages (Duplín and Potoky) in north-eastern Slovakia during 2015–2017 from small private farmstead buildings, i.e. in breeding yards with poultry, pigs and pigeons. Analysis of the demographic structure of the mouse populations showed that the sex ratio did not deviate from a 1:1 ratio. The prevalence of adult mice was significantly higher than of subadults, and this was particularly noticeable in females. The season did not affect the litter size (mean ± SD = 4.9 ± 1.5, with 2–8 embryos) in mice, and winter breeding was confirmed. Results from our microbiological analysis showed that the house mouse populations inhabiting small farmstead buildings could be important reservoirs of potentially pathogenic and multidrug-resistant bacteria.

室内小家鼠共297人1758年的Linnaeus在2015-2017年期间被困在斯洛伐克东北部的两个村庄（Duplín和Potoky）中，这些村庄来自小型私人农舍建筑，即家禽，猪和鸽子的繁殖场。小鼠种群的人口统计结构分析表明，性别比例没有偏离1：1的比例。成年小鼠的患病率明显高于亚成年小鼠，这在雌性动物中尤为明显。季节没有影响小鼠的产仔数（平均数±SD = 4.9±1.5，有2-8个胚胎），并确认了冬季繁殖。我们的微生物学分析结果表明，居住在小型农舍内的家鼠种群可能是潜在致病和耐多药细菌的重要储存库。
