Which of the following is a potential complication of bacterial infections from dog bites?

Sepsis is a serious and potentially life-threatening complication that can arise from bacterial infections following dog bites. When a dog bite occurs, bacteria from the dog's mouth can enter the human body, leading to localized infections. If these infections are not treated adequately, they can progress and enter the bloodstream, resulting in sepsis. Some signs of sepsis include fever, increased heart rate, rapid breathing, and confusion. If not recognized and managed swiftly, sepsis can lead to septic shock and organ failure, making it a critical complication stemming from dog bites.

Other options such as psoriasis, myocardial infarction, and chronic fatigue syndrome are not directly associated with complications from dog bite infections. Psoriasis is a chronic skin condition, myocardial infarction is related to cardiac events often influenced by factors like atherosclerosis, and chronic fatigue syndrome is characterized by prolonged fatigue and other symptoms without a clear infectious cause. Thus, they do not connect in a direct causal manner to bacterial infections from dog bites like sepsis does.
