Bioaerosols include fungi, bacteria, viruses, and pollen.Their concentrations are greatest in the planetary boundary layer (PBL) and decrease with altitude. Survival rate of bioaerosols depends on a number of biotic and abiotic factors which include climatic conditions, ultraviolet (UV) light, temperature and humidity, as well as resources present within dust or clouds.
Indoor bioaerosols may originate from outdoor air and indoor reservoirs. [3] [4] Although outdoor bioaerosols cannot easily migrate into large buildings with complex ventilation systems, certain categories of outdoor bioaerosols (i.e., fungal spores) do serve as major sources for indoor bioaerosols in naturally ventilated buildings at specific periods of time (i.e., growing seasons for fungi).

An inoculation loop (also called a smear loop, inoculation wand or microstreaker) is a simple tool used mainly by microbiologists to pick up and transfer a small sample of microorganisms called inoculum from a microbial culture, e.g. for streaking on a culture plate. [1] [2] This process is called inoculation.
An inoculation needle is an essential tool in inoculating a stab culture. [ 4 ] [ 7 ] A sterile stab culture cap is removed and the open end is flamed. The needle tip and its length is then pushed into the stab media and stopped once the needle tip reaches 0.5 inches away from the bottom of the stab media. [ 7 ]
The Diamond Calk Horseshoe Company of Duluth, Minnesota, USA was founded in 1908 by blacksmith Otto Swanstrom.. Initially manufacturing horseshoes with a special type of calk to improve the animals' foothold on slippery surfaces, the company successfully adapted to the development of motorised transport for the masses and produced a range of adjustable wrenches and pliers from the 1920s.
In biology, inoculum (pl.: inocula) refers to the source material used for inoculation. Inoculum may refer to: In medicine, material that is the source of the inoculation in a vaccine
Cell spreaders. In microbiology, a cell spreader or plate spreader is a tool used to smoothly spread cells and bacteria on a culture plate, such as a petri dish.. Cell spreaders can be made from glass, plastic, or metal, and come in various shapes.
The cost of a biological weapon is estimated to be about 0.05 percent the cost of a conventional weapon in order to produce similar numbers of mass casualties per kilometer square. [67] Moreover, their production is very easy as common technology can be used to produce biological warfare agents, like that used in production of vaccines, foods ...
