Bacillus of haemorrhagic septicaemia, also known as Pasteurella multocida, is a type of bacteria that causes a severe and often fatal disease known as haemorrhagic septicaemia in various animal species, particularly domestic livestock. Haemorrhagic septicaemia is characterized by high fever, hemorrhaging in multiple organs, difficulty in breathing, lethargy, and ultimately, death.
This gram-negative, rod-shaped bacterium is a facultative anaerobe, meaning it can survive in both oxygen-rich and oxygen-poor environments. It possesses a polysaccharide capsule that helps it evade the host's immune response, allowing it to cause severe infections. The bacterium primarily targets the respiratory system, causing inflammation and necrosis of the respiratory tract, which can quickly lead to systemic infection.
Bacillus of haemorrhagic septicaemia is usually transmitted through close contact between infected and susceptible animals, such as through inhalation of respiratory droplets or ingestion of contaminated feed or water. It can also enter the bloodstream directly through wounds or other open avenues, contributing to the rapid dissemination of the bacteria throughout the body.
Effective prevention and control strategies for haemorrhagic septicaemia typically involve vaccination of susceptible animals, proper hygiene practices, quarantine measures, and prompt treatment with antibiotics. Early diagnosis is crucial for successful treatment, as haemorrhagic septicaemia progresses rapidly.
Overall, Bacillus of haemorrhagic septicaemia is a highly infectious and pathogenic bacterium that poses a significant threat to animal health and livestock industries worldwide.
