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.
The inoculation loop is first sterilized by passing it through a flame. When the loop is cool, it is dipped into an inoculum such as a broth or patient specimen containing many species of bacteria. The inoculation loop is then dragged across the surface of the agar back and forth in a zigzag motion until approximately 30% of the plate has been ...
An inoculation needle is a laboratory equipment used in the field of microbiology to transfer and inoculate living microorganisms. [1] [full citation needed] It is one of the most commonly implicated biological laboratory tools and can be disposable or re-usable. [1] A standard reusable inoculation needle is made from nichrome or platinum wire ...
When responding to a possible outbreak, health officials should consider which is best, ring vaccination or mass vaccination.In some outbreaks, it might be better to only vaccinate those directly exposed; variable factors (such as demographics and the vaccine that is available) can make one method or the other safer, with fewer people experiencing side-effects when the same number are ...
The phage can then be isolated from the resulting plaques in a lawn of bacteria on a plate. Viral cultures are obtained from their appropriate eukaryotic host cells. The streak plate method is a way to physically separate the microbial population, and is done by spreading the inoculate back and forth with an inoculating loop over the solid agar ...
Genetic testing, such as via polymerase chain reaction (PCR), DNA microarray, and loop-mediated isothermal amplification, may be used to detect whether bacteria possess genes which confer antibiotic resistance. [9] [23] An example is the use of PCR to detect the mecA gene for beta-lactam resistant Staphylococcus aureus. [9]
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.
Some injectors are triggered by simply pushing the nose ring against the injection site. In these designs, the protective cap is the primary safety. Other designs use a safety mechanism similar to nail guns : The injection is triggered by pushing the nose ring against the injection site and simultaneously, while applying pressure, pushing a ...
