“…Upon calibration using the FA-1 sampler calibration table, the quantity of aerobic bacteria was calculated based on sampling time and sampling flow rate (Rosas et al, 2001). The colonies on agar plates were isolated and purified, and the identities of isolated bacterial strains were verified using a conventional Analytical Profile Index (API) system.…”

Numerous studies have been conducted to analyse bacterial aerosols in animal houses, which is beneficial for the control of animal diseases. However, little information on aerosols in enclosed rabbit sheds was available. An FA-1 sampler was employed to collect air samples in an enclosed rabbit house in the Qingdao region of China. Concentration, composition, and aerodynamics of bacterial aerosols inside the enclosed rabbit shed were systematically analysed. The concentration of airborne bacteria inside the rabbit shed was 2.11-6.36×10 4 colony forming unit/m 3 (CFU/m 3 ). Seventeen species of bacteria belonging to eight genera were identified. Among these, there were 11 species belonging to 4 genera of gram-positive bacteria, and 6 species belonging to 4 genera of gram-negative bacteria. The dominant species of bacteria were, in descending order, Micrococcus luteus (49.4%), Staphylococcus epidermidis (25.5%), and Alcaligenes odorans (10.2%). A total of about 76.3% of airborne bacteria was distributed in stages C-F of the FA-1 sampler (that ranges from A to F), with aerodynamic radii <3.3 µm in diameter. These particulates could enter lower respiratory tracks and even alveoli, posing a potential threat to the health of both animals and breeders.

Airborne bacteria, fungi, and endotoxin levels in residential microenvironments: a case study

Limited data are currently available on the concentrations of airborne bacteria, fungi, and endotoxins in indoor environments. The levels of aerial bacteria and fungi were measured at several microenvironments within a well-ventilated residential apartment in Singapore including the living room, kitchen, bedroom, toilet, and at a workplace environment by sampling indoor air onto culture medium plates using the 6-stage Andersen sampler. Total microbial counts were determined by collecting the air samples in water with the Andersen sampler, staining the resultant extracts with a fluorescent dye, acridine orange, and counting the microbes using a fluorescent microscope. The levels of airborne endotoxins were also determined by sampling the airborne microorganisms onto 0.4 lm polycarbonate membrane filter using the MiniVol sampler at 5 l/min for 20 h with a PM 2.5 cut-off device. The aerial bacterial and fungal concentrations were found to be in the ranges of 117-2,873 CFU/m 3 and 160-1,897 CFU/m 3 , respectively. The total microbial levels ranged from 49,000 to 218,000 microbes/m 3 . The predominant fungi occurring in the apartment were Aspergillus and Penicillium while the predominant bacterial strains appeared to be Staphylococcus and Micrococcus. The average indoor endotoxin level was detectable in the range of 6-39 EU/m 3 . The amount of ventilation and the types of human activities carried out in the indoor environment appeared to be important factors affecting the level of these airborne biological contaminants.
