What is a potential consequence of antibiotic treatment for glanders?

• A. Potential development of asymptomatic carriers
• B. Immediate cure
• C. No carriers
• D. Vaccine-induced immunity

Answer: (A)

The key idea is that treatment can suppress disease without completely eradicating the bacteria, leading to a carrier state. Glanders is caused by Burkholderia mallei, which can persist in parts of the host, such as the nasal mucosa. Antibiotics may clear clinical signs, but if bacteria remain, the animal can appear normal while shedding the organism and transmitting it to other horses or even people. This means a potential consequence of antibiotic treatment is the development of asymptomatic carriers. Immediate cure or elimination of all carriers is not guaranteed by treatment, and there is no standard vaccine-induced immunity to rely on in this context.
