Regardless of the cfu counts, corrective actions must be dictated by the identification of the microorganisms recovered. Do not disinfect gloves with Isopropyl alcohol immediately prior to sampling. Aureobasidium spores are difficult to identify on spore traps because of morphologic variation. Follow your training practices 4. The compounding process includes complex aseptic manipulations other than the single volume transfer. Coveralls and coats can be used for one shift.
Personnel shall perform didactic review, writ-ten testing, media fill testing or aseptic manipulative shills initially and at least annually for low and medium risk levels and semi annually for high risk level compounding. Its most distinguishing feature is the production of primary blastospores spores produced by a budding process arising directly from pigmented, vegetative hyphae on short denticles protuberances in the hyphae. The brown hyphae can differentiate to form chlamydospores resting spores or arthroconidia a spore type resulting from fragmentation of a hypha at maturity. Filling of reservoirs of injection and infusion devices with multiple sterile drug products 3. While sampling in addition to documenting sample location, volume of air collected, etc. Don't contaminate compounding surfaces, products, raw material or analytical samples 5.
Media fill challenge testing will be used to access the quality of aseptic skills. In the absence of any adverse comments the proposed revisions will become official on December 1, 2019. The mycelium is characterized by irregular, dichotomous two part branching, with cells sometimes rounding off and separating, and is variable in thickness. When swabbing is used in sampling, the area covered should be greater than or equal to 24cm 2 but no larger than 30 cm 2. In culture, Aureobasidium species grow rapidly on and, at first, produce colonies that are yeast-like and cream or pink in color. Products manufactured as an aseptic parenteral have the greatest risk, and therefore the greatest level of control over manufacturing must be proven. Aureobadisium pullulans has been used to produce pullulan, a biodegradable polysaccharide which, when processed, becomes a shiny and strong fiber used to package food and drugs.
Junctures of ceilings to walls should be coved and caulked. Please see for submitting public comments on. The comment period for this revision ends on November 30, 2018. All other coverings are to be discarded and new ones donned prior to reentry. .
Impaction on a media plate is the preferred method for culturable air sampling. This article was originally published on September 2008. Transfer of multiple ampules or vials into a single final container or product 1. If ceilings consist of inlaid panels, the panels should be impregnated with a polymer to render them impervious and hydrophobic and they should be caulked around each perimeter to seal them to the support frame. The compounded sterile products do not contain broad spectrum bacteriostatic substances and they are administered over several days. Consideration must be given to the overall effect the chosen sampling method may have on the unidirectional airflow within a compounding environment. Procedure involve only a few closed system, basic, simple aseptic transfers and manipulations 4.
As the colony ages, a slimy exudate appears and the coloration changes to dark brown or black on the surface. Any colony forming unit cfu count that exceeds its respective action level should prompt a re-evaluation of the adequacy of personnel work practices, cleaning procedures, operational procedures, and air filtration efficiency within the aseptic compounding location. For high risk preparations in the absence of passing a sterility test the storage periods cannot exceed the following; 24 hours at controlled room conditions, 3 days at cold temperatures and 45 days for solid frozen state at -20 C or colder. As seen from the reverse side of the agar plate the colony is a pale beige. Sampling for the airborne viable particles must be conducted based on a risk assessment of the compounding activities performed. Should you have any questions, please contact Jeanne Sun, Manager to the Compounding Expert Committee.
Environmental monitoring data must be collected and trended as a means of evaluating the overall control of the compounding environment. We use science and innovation to provide accurate data that people trust and to create solutions that save time and resources. Comments should include corresponding line number s to the proposed revisions to the General Chapter. The spores may be hyaline colorless or pigmented, variable in size, one-celled, ellipsoid or ovoid, and completely encased in a slimy coat. Filling of reservoirs of injection and infusion devices with volumes of sterile drug solutions that will be administered over several days at ambient temps between 25-40 C 4. There are approximately 20 accepted species in this genus with the most commonly known being A.
Generally, we report irregular clumps of dark brown hyphae, dividing in more than one plane to form chlamydospores, as A. This genus has also been observed to grow on textiles, foodstuffs, fruits and painted surfaces. Air Sampling: Use an impaction sampler to collect as much air as possible without drying the media. The purpose of the regulation is to prevent infections in patients using pharmaceutical products, as well as to protect pharmacy staff members that are ordinarily exposed to pharmaceutical products. When sampling at these higher sampling volumes, we strongly suggest verifying that the manufacturer states that the device is capable of taking these volumes without drying out the media. The spores are usually disseminated by wind when dry and water.
The compounding process requires and unusually long duration, such as that required to complete dissolution or homogenous mixing. It has also been used industrially to remove unwanted components of raw textile materials. The barrier isolator should be supported by adequate procedures for operation, maintenance, monitoring, and control. Because this fungus is sticky and slimy, spores do not readily become airborne and are not commonly found on spore traps. Surfaces should be resistant to damage from sanitizing agents. Both air and surface samples may be taken based on the requirements of the individual situation.
