Which two bacteria are commonly associated with pneumonia in guinea pigs?

• A. Bordetella bronchiseptica and Streptococcus pneumoniae
• B. Pasteurella multocida and Escherichia coli
• C. Staphylococcus aureus and Bacillus subtilis
• D. Mycobacterium avium and Pseudomonas aeruginosa

Answer: (A)

Two bacteria most commonly linked to pneumonia in guinea pigs are Bordetella bronchiseptica and Pasteurella multocida. Bordetella bronchiseptica is a respiratory pathogen that irritates the airways and disrupts normal mucociliary clearance, setting the stage for infection. Pasteurella multocida is a frequent opportunistic invader that can descend from the upper airways into the lungs, especially when the animal is stressed, housed in crowded conditions, or has a concurrent viral URI. Together, they explain the typical bronchopneumonia seen in guinea pigs, often as part of a mixed respiratory disease complex. While other bacteria can cause pneumonia in various species, these two are the classic culprits in guinea pigs.
