- Abstract:
- 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 andStaphylococcusspp., especially the speciesS. 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 x 10(5) cfu/m(3)and dropped to 2.6 x 10(5) cfu/m(3)with increasing growth of the swine. The concentration ofStaphylococcusspp. was 8.8 x 10(4) cfu/m(3)and decreased to 9.4 x 10(3) cfu/m(3)by the end. In the empty barn, the total concentration of mesophilic bacteria was 9.1 x 10(4) cfu/m(3)and forStaphylococcusspp., 1.1 x 10(4) cfu/m(3). At the beginning of the second series of measurements, the total concentration of mesophilic bacteria was 6.6 x 10(4) cfu/m(3)and dropped to 4.4 x 10(4) cfu/m(3)with the increasing growth of the piglets. The concentrations ofStaphylococcusspp. fluctuated along the second measurement series. The speciesStaphylococcus aureuswas 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.
