A 41-year-old male presents to the emergency department with a 5-day history of flu-like symptoms, fever, cough, and now shortness of breath. This chapter will discuss laboratory and vivarium facilities used at Biosafety Level 2 and Biosafety Level 3. Class II Type A1 cabinets recirculate HEPA filtered air into the room, and are generally adequate for changing of contaminated cages and other procedures that do not involve flammable or toxic chemicals or vapors. These spaces often must be decontaminated, and reconfigured to support individual research protocols. In addition to protection from infectious agents, diagnostic laboratory staff must also be protected during postmortem examinations from physical injury by sharp instruments, power tools, heavy carcasses, noise, and slips and falls, and from chemical injury or hypersensitivity reactions to fixatives, disinfectants, cleaning solutions, animal-derived allergens, and toxins. Since air locks do not allow continuous airflow through the cracks under the doors, they require HEPA filtered transfer grilles, control systems, or special system balancing to ensure containment. If recirculated back into the room, the air should pass through a HEPA filter. OVERVIEW. HEPA filtration of the supply air may be warranted if there is a desire for very clean air in the containment facility. Pseudotyped lentiviruses bearing hantavirus Gn/Gc proteins have been used to characterize the fusion loops within Gc (Cifuentes-Muñoz et al., 2011) and to selectively transduce vascular endothelial cells (Qian et al., 2006). Utilize professional vermin control personnel to provide control plans. By continuing you agree to the use of cookies. These include all medical and nonmedical implements that come into contact with Salmonella-infected or at-risk horses. Sterilization involves the destruction of all microbial life. Ideally, these items should be manufactured to be readily decontaminated or incinerated when no longer in use. Tradeline’s 27th annual animal research and biocontainment facilities conference details the new standards and solutions for lower operating and labor costs, flexibility, high space utilization, and facility decisions relative to recurring directional shifts in research and species, regulatory compliance, safety, and security. View Mobile Biocontainment Equipment Germfree is internationally recognized as a leading manufacturer of Biological Safety Cabinets. Different types of biological safety cabinets have different exhaust requirements (Richmond and Mckinney, 2000). A cart is required on both sides of the autoclave to hold the load rack outside of the chamber as the cages are loaded onto and off the load rack. The product type to be used should be considered, as well as the regular implementation of the methods by hospital personnel. Examples might include cardboard tubes and small nylon chew bones for rodents, shredded paper/foraging boxes for primates, and large smooth-surfaced balls or stainless steel chains for pigs. The most efficient way to maintain both barrier and containment conditions is the distributive approach in which the autoclave is an integral part of the parameter of a dedicated barrier and/or containment area, so that items can be autoclaved either into or out of the area, thus eliminating the need to wrap or otherwise protect items to be autoclaved. Danielle B. Pedrolli, ... Graciely G. Correa, in Precision Medicine for Investigators, Practitioners and Providers, 2020. Research and manufacture of biopharmaceutical products involves the use of genetically engineered (GE) organisms and/or pathogenic organisms. Ventilated containment caging can be recirculated back into the room or exhausted to the outside. In the hospital, horses are more likely to shed or acquire an infectious agent than those in the general population because they are more likely to be under stress, may be less able to respond immunologically to infectious agents, have altered nutrition or disturbances in normal flora, may be receiving antimicrobials, may undergo procedures that are known risk factors for infection of various types, and are concentrated in close proximity with other animals that have similar risk factors. A co-worker has been complaining of some of the same symptoms since yesterday. Since aquatic facilities are “wet” facilities, the media that gives lives to organisms also facilitates the spread of potential pathogens. Block open rafters in barns using wire mesh nailed to the rafters to reduce bird roosting above horse stalls and feed storage areas. Specifically, the VSV glycoprotein is targeted to the plasma membrane, which is the site of VSV budding (Brown and Lyles, 2003; Green et al., 1981; Johnson et al., 1998), whereas hantavirus Gn/Gc proteins are largely targeted to the Golgi complex (Deyde et al., 2005; Pensiero and Hay, 1992; Ruusala et al., 1992; Spiropoulou, 2001; Spiropoulou et al., 2003) and Old World hantaviruses bud into this organelle (Hung, 1988; Hung et al., 1983). Control measures included cleaning and disinfection of the surfaces in the foaling barn, thorough bathing of mares immediately after foaling, frequent removal of mare's feces from the stall, and giving the newborn foal colostrum from a bottle before suckling from the udder. They also place a heavy demand on building HVAC systems, as they exhaust a large volume of air and operate at a significantly higher system static pressure than do Class II Type A BSCs (NSF/ANSI 49 2002). Biosafety Course Overview. Bruce Whitney, in Ensuring National Biosecurity, 2016. Eva Mittler, ... Rohit K. Jangra, in Advances in Virus Research, 2019. There is . The skid for the autoclaves can also be located in the interstitial space. BSL2 . FAD PReP/NAHEMS Guidelines: Biosecurity - Overview. Enrichment items used in biocontainment facilities should not contribute to pathogen aerosol but should be selected to improve environmental complexity. For high-level biocontainment, redundancy of the exhaust system is a must. Vector Biocontainment Laboratory. can be minimized by reducing chances of oral exposure to the organism. We utilize cell cultures from humans, insects, plants, and animals and genetically engineer them for our therapies. ScienceDirect ® is a registered trademark of Elsevier B.V.

Heinz Feldmann, in, Encyclopedia of Virology (Second Edition), Because Marburg and Ebola viruses are highly virulent, special precautions need to be taken when samples are handled, and for some procedures, To avoid health risks to personnel, the zoonotic risk should be managed in a very specific way. Containment of biohazards is the goal of a biosafety program and combinations of specific elements in the triad of containment controls (i.e., safe methods, facilities and equipment) have been grouped into increasing levels of protection labeled Biosafety Levels (BSL), with BSL-1 appropriate for work with agents with the least risk and BSL-4 required for work with agents with the greatest risk. Moreover, healthcare providers will have to be trained to deal with bioengineered microorganisms, and detailed protocols will have to be established. After treatment, a clearance protocol should be taken to eliminate therapeutic microbes from patients to prevent unintended consequences. On the plus side, the educational facilities category in August advanced 17 percent, lifted by the start of the $705 million National Bio and Agro-Defense Facility in Manhattan, Kan., which is a biocontainment laboratory for the Department of Homeland Security that will study diseases affecting the nation's agricultural industry and public health. Test. At ABSL2, ABSL3 and ABSL4, biological safety cabinets can be recirculated back into the room, directly exhausted to the outside through the building exhaust system or indirectly exhausted by use of an air gap (thimble) connection. Lehner, ... Mark E. Fitzgerald, in Planning and Designing Research Animal Facilities, 2009. Living therapeutics must be equipped with efficient, Such items can be introduced through a vestibule or fumigation chamber. Their rule of thumb is that adding an anteroom to a laboratory or animal room creates a LPF of 100 from the room where the hazard might be generated. As a rule of thumb, there should be a minimum airflow of 100 cfm through doors when opened to maintain directional movement of air. Regardless of the size, autoclaves to be used for routinely autoclaving cages and other animal-care supplies should be pit mounted and floor loading (Figure 31-23) to achieve maximum operational efficiency. A central arrangement may involve having a double-door pass-through autoclave located between the soiled and clean sides of the cage sanitation area so that it can be used for decontaminating items taken out of, Heating, Ventilation and Air Conditioning (HVAC), ACH) when controlling airborne particles is a high priority. Directional airflow should enter the facility corridor, go into the anteroom and then into the animal holding room, where the air will be exhausted. Pseudotyped VSVs have also enabled the production of large viral preparations necessary to efficiently evaluate neutralizing antibodies against both Old World and New World hantaviruses (Higa et al., 2012; Kallio-Kokko et al., 2001; Lee et al., 2006; Levanov et al., 2019; Ogino et al., 2003; Paneth Iheozor-Ejiofor et al., 2016) and immunization with these viruses induces production of neutralizing antibodies and protection in animal models (see Section 10 for details) (Brown et al., 2011; Lee et al., 2006; McClain et al., 2000; Prescott et al., 2014). Not all hantavirus glycoproteins are amenable to efficient pseudotyping in VSV vectors, however, likely due to a mismatch in the sites of VSV and hantavirus budding within cells. Because the performance of postmortem examinations and long hours sitting at the microscope and computer can also result in fatigue and physical injury, ergonomic desks, chairs, and instruments, including microscopes, should be part of the occupational health program.

In cases where pit mounting is not an option, a low-profile platform lift with a modest ramp can be used to raise autoclave load carts or other rolling equipment from the floor to the level of the bottom of the autoclave chamber and back to the floor. Cleaning and disinfection of equipment used on equine patients between uses or use of dedicated equipment for high-risk patients is important in controlling spread of Salmonella between hospitalized patients. This roadblock has been eased by the development of surrogate viral systems bearing the hantavirus glycoproteins, Gn/Gc, which are necessary and sufficient for hantavirus entry. Whether or not the additional autoclaves that may be required for the distributive approach make this method cost-effective as compared to the more labor-intensive central approach depends on the volume of materials to be autoclaved. The location or locations of the autoclave(s) depends on how they will be used, how many autoclaves will be installed, and, to a large degree, the operational philosophy of the planning team. Most barrier facilities would not have a fumigation chamber such as would be used in a high-level, Hendra and Nipah Virus Attack (Hendra Virus Disease and Nipah Virus Encephalitis), Special Fixed Equipment for research Animal Facilities, The location or locations of the autoclave(s) depends on how they will be used, how many autoclaves will be installed, and, to a large degree, the operational philosophy of the planning team. Animals may need to be individually housed … During viremia particles can usually be visualized by electron microscopy. Assuming containment caging and protocols provide a minimum LPF of 100, the anteroom creates an LPF of 100 and the door from the anteroom to the corridor creates and additional LPF of 100, a six log (1,000,000×) reduction in the aerosol contamination from the containment caging to the corridor has been created. In instances where small volumes of chemicals are used, Class II Type A2 cabinets with an air gap connection to the facility exhaust system, or Class II Type B1 cabinets may be appropriate. Housing horses in veterinary hospitals based on risk level may reduce cross-contamination between patients. For confirmation virus isolation should be initiated in appropriate cell cultures (Vero E6 cells, MA 104 cells) from acute-phase serum or biopsy/autopsy materials (liver, spleen, lymph nodes, kidney, heart). Fellow in the National Biosafety and Biocontainment Training Program . David R. Smith, in Food Animal Practice (Fifth Edition), 2009, Biosecurity is the sum of actions taken to prevent introducing a disease agent into a population (pen, herd, region), whereas biocontainment describes the actions taken to control a pathogen already present in the population.39 In theory outbreaks of undifferentiated neonatal calf diarrhea could be prevented by eliminating the pathogens, decreasing calf susceptibility, or altering the production system to reduce opportunities for pathogen exposure and transmission.
