Which of the following agents is associated with bio-safety level 2?

Which of the following agents is associated with bio-safety level 2?

• A. Canine hepatitis
• B. Salmonella
• C. Ebola
• D. HIV

Answer: (B)

Bio-safety level 2 (BSL-2) is a classification used to denote a containment level for handling pathogens that are associated with human disease but pose a moderate risk to laboratory personnel and the environment. These pathogens typically have the potential to cause illness in healthy adults but are not easily transmitted through the air. Salmonella is correctly linked to biosafety level 2 because it is a well-known pathogen that can cause foodborne illness. It is usually transmitted through ingestion of contaminated food or water. In a laboratory setting, standard precautions and practices can effectively manage the risks posed by Salmonella, making it appropriate for BSL-2 containment. In contrast, the other agents listed are associated with higher levels of containment due to their more severe implications for human health. Canine hepatitis is generally not classified at this level because it is primarily a disease in dogs and poses limited risk to humans. Ebola, classified as a BSL-4 agent, presents a high risk, being highly contagious and potentially fatal. HIV, while manageable under certain conditions, is typically classified as BSL-2 but often requires specific safety practices given its modes of transmission and the serious health implications for infected individuals. Thus, Salmonella’s characteristics and the associated risks
