The investigation of bioaerosols in the recent years has become more important both indoors and outdoors. Due to expanding of livestock farm capacity, raising attention is paid to this source of emissions. The objective of the present study was to estimate the distribution of bioaerosols in the animal husbandry and its surroundings. Over 2 fattening periods with different animal ages and weights, the main emphasis was put on the total concentrations of mesophilic bacteria and Staphylococcus spp., especially the species S. aureus. The bioaerosols were sucked in with an AGI-30 Impinger, and nasal and neck skinfold swab samples were collected supplementary from randomly selected pigs. From the first series of measurements, the total concentration of mesophilic bacteria was 6.2 × 105 cfu/m3 and dropped to 2.6 × 105 cfu/m3 with increasing growth of the swine. The concentration of Staphylococcus spp. was 8.8 × 104 cfu/m3 and decreased to 9.4 × 103 cfu/m3 by the end. In the empty barn, the total concentration of mesophilic bacteria was 9.1 × 104 cfu/m3 and for Staphylococcus spp., 1.1 × 104 cfu/m3. At the beginning of the second series of measurements, the total concentration of mesophilic bacteria was 6.6 × 104 cfu/m3 and dropped to 4.4 × 104 cfu/m3 with the increasing growth of the piglets. The concentrations of Staphylococcus spp. fluctuated along the second measurement series. The species Staphylococcus aureus was detected in nasal swabs of selected swine including MRSA. Temperature and humidity had no influence on the concentrations of mesophilic bacteria in the swine barn.

猪舍中育肥期间的生物气溶胶测量重点关注葡萄球菌属的存在。

近年来，生物气溶胶的研究在室内和室外都变得更加重要。由于畜牧养殖场容量的扩大，这一排放源受到越来越多的关注。本研究的目的是估计生物气溶胶在畜牧业及其周围环境中的分布。超过2个不同动物年龄和体重的育肥期，主要重点放在嗜温细菌和葡萄球菌属的总浓度上，特别是金黄色葡萄球菌。用 AGI-30 Impinger 吸入生物气溶胶，并从随机选择的猪身上补充收集鼻和颈部皮褶拭子样本。从第一组测量中，嗜温细菌的总浓度为 6.2 × 105 cfu/m3，并下降到 2。6 × 105 cfu/m3 随着猪的生长增加。葡萄球菌属的浓度。为 8.8 × 104 cfu/m3，最后下降到 9.4 × 103 cfu/m3。在空猪舍中，嗜温细菌的总浓度为 9.1 × 104 cfu/m3，葡萄球菌属的总浓度为 1.1 × 104 cfu/m3。在第二轮测量开始时，嗜温细菌的总浓度为 6.6 × 104 cfu/m3，随着仔猪生长的增加而下降到 4.4 × 104 cfu/m3。葡萄球菌属的浓度。沿着第二个测量系列波动。在包括 MRSA 在内的选定猪的鼻拭子中检测到金黄色葡萄球菌。温度和湿度对猪舍中嗜温细菌的浓度没有影响。8 × 104 cfu/m3 并最终降至 9.4 × 103 cfu/m3。在空猪舍中，嗜温细菌的总浓度为 9.1 × 104 cfu/m3，葡萄球菌属的总浓度为 1.1 × 104 cfu/m3。在第二轮测量开始时，嗜温细菌的总浓度为 6.6 × 104 cfu/m3，随着仔猪生长的增加而下降到 4.4 × 104 cfu/m3。葡萄球菌属的浓度。沿着第二个测量系列波动。在包括 MRSA 在内的选定猪的鼻拭子中检测到金黄色葡萄球菌。温度和湿度对猪舍中嗜温细菌的浓度没有影响。8 × 104 cfu/m3 并最终降至 9.4 × 103 cfu/m3。在空猪舍中，嗜温细菌的总浓度为 9.1 × 104 cfu/m3，葡萄球菌属的总浓度为 1.1 × 104 cfu/m3。在第二轮测量开始时，嗜温细菌的总浓度为 6.6 × 104 cfu/m3，随着仔猪生长的增加而下降到 4.4 × 104 cfu/m3。葡萄球菌属的浓度。沿着第二个测量系列波动。在包括 MRSA 在内的选定猪的鼻拭子中检测到金黄色葡萄球菌。温度和湿度对猪舍中嗜温细菌的浓度没有影响。在第二轮测量开始时，嗜温细菌的总浓度为 6.6 × 104 cfu/m3，随着仔猪生长的增加而下降到 4.4 × 104 cfu/m3。葡萄球菌属的浓度。沿着第二个测量系列波动。在包括 MRSA 在内的选定猪的鼻拭子中检测到金黄色葡萄球菌。温度和湿度对猪舍中嗜温细菌的浓度没有影响。在第二轮测量开始时，嗜温细菌的总浓度为 6.6 × 104 cfu/m3，随着仔猪生长的增加而下降到 4.4 × 104 cfu/m3。葡萄球菌属的浓度。沿着第二个测量系列波动。在包括 MRSA 在内的选定猪的鼻拭子中检测到金黄色葡萄球菌。温度和湿度对猪舍中嗜温细菌的浓度没有影响。在包括 MRSA 在内的选定猪的鼻拭子中检测到金黄色葡萄球菌。温度和湿度对猪舍中嗜温细菌的浓度没有影响。在包括 MRSA 在内的选定猪的鼻拭子中检测到金黄色葡萄球菌。温度和湿度对猪舍中嗜温细菌的浓度没有影响。
