PASTEURELLA HAEMOLYTICA Meaning and
Definition
-
Pasteurella haemolytica is a gram-negative bacterium belonging to the Pasteurellaceae family. It is commonly found in the respiratory tract and oral cavity of various animals, especially domesticated livestock such as cattle and sheep. This bacterium is known to be a significant pathogen in veterinary medicine, particularly in causing respiratory diseases in these animals.
Pasteurella haemolytica is primarily responsible for bovine respiratory disease complex (BRDC), which is a highly contagious and debilitating syndrome affecting cattle. It is one of the leading causes of morbidity and mortality in feedlot cattle and causes severe economic losses to the livestock industry.
The bacterium can be transmitted between animals through direct contact or inhalation of respiratory secretions. Once established in the respiratory tract, Pasteurella haemolytica adheres to the respiratory epithelium and produces various toxins that damage the lung tissue, leading to clinical symptoms like coughing, fever, nasal discharge, and difficulty in breathing.
In severe cases, this bacterium can lead to pneumonia, causing consolidation of lung tissue and decreased oxygen exchange. Pasteurella haemolytica can also cause septicemia, leading to systemic inflammation and endotoxemia, which further exacerbate the respiratory symptoms.
Effective prevention and control of Pasteurella haemolytica infections in livestock involve strategies such as vaccination, proper nutrition, and reducing stress factors. Early diagnosis and treatment of the disease with antibiotics are also crucial to minimize the impact of the infection and prevent its spread within the herd.

Etymology of PASTEURELLA HAEMOLYTICA
The word "Pasteurella haemolytica" is formed by combining two different components: "Pasteurella" and "haemolytica".
1. "Pasteurella": This component of the word is derived from the name Louis Pasteur, a French chemist and microbiologist who is known for his numerous contributions to the field of microbiology. Pasteur discovered Pasteurella multocida, another bacterium within the genus Pasteurella, and therefore the genus was named after him.
2. "Haemolytica": This component is derived from the Greek word "haima" meaning "blood" and the suffix "-lytic" derived from "lýsis", meaning "loosening" or "dissolving". Therefore, "haemolytica" refers to the ability to lyse or break down red blood cells.
