Plague (Yersinia pestis) is transmitted to humans primarily through:
Answer: The bite of infected fleas from rodents
Plague is most commonly transmitted via the bite of an infected flea, particularly the oriental rat flea (Xenopsylla cheopis), which acquires the bacterium from infected rodents.
A pest management professional recommends installing door sweeps on all exterior doors of a food facility. This recommendation addresses which aspect of pest management?
Answer: Exclusion to prevent pest entry
Door sweeps seal the gap at the bottom of doors, preventing rodents, cockroaches, and other pests from entering the facility — an exclusion measure.
Which condition is most likely to promote fungus gnat infestations in an interior plant display?
Answer: Overwatering potted plants, creating wet soil conditions
Fungus gnats breed in moist soil rich in organic matter; overwatered plants provide the ideal wet conditions for larval development.
The primary public health justification for controlling feral pigeon populations in urban environments is:
Answer: Reduction of histoplasmosis risk and ectoparasite (mite) infestations associated with accumulating droppings and nests
Pigeon droppings accumulate fungal spores (Histoplasma capsulatum) and support ectoparasites like mites, presenting direct public health risks.
When cleaning up a rodent-infested area suspected of hantavirus contamination, which practice is MOST critical?
Answer: Wearing an N95 respirator and wetting materials with disinfectant before removal
Wetting droppings with a disinfectant (e.g., 10% bleach solution) before removal prevents aerosolization of hantavirus particles, and an N95 respirator protects against inhalation.
Which arthropod-borne disease is directly associated with poor sanitation and overcrowding due to its louse vector?
Answer: Trench fever (Bartonella quintana)
Trench fever, caused by Bartonella quintana, is transmitted by the body louse and is endemic in populations with poor hygiene and overcrowded conditions.
A 'clean-out' treatment for cockroaches in a commercial kitchen should ALWAYS be followed by:
Answer: A sanitation program to eliminate food, water, and harborage that sustained the infestation
Without addressing the underlying sanitation deficiencies, cockroach populations will reestablish because the resources supporting them remain available.
