Bordetella is a genus of bacteria known for causing respiratory infections in humans and animals. The most well-known species, Bordetella pertussis, is responsible for whooping cough, a highly contagious disease that primarily affects children. Other species, like Bordetella bronchiseptica, can cause respiratory issues in pets, particularly dogs. These bacteria are typically spread through respiratory droplets when an infected person coughs or sneezes. Vaccines are available to protect against Bordetella pertussis, and maintaining good hygiene practices can help reduce the risk of infection. Early diagnosis and treatment are essential for managing symptoms effectively.
