What does the word "Pasteurelleae" mean?

The term "Pasteurelleae" refers to a specific group of bacteria within the family Pasteurellaceae. This family is known for its diverse members, some of which are significant in veterinary and human medicine. Understanding the term "Pasteurelleae" requires delving into the taxonomy of these organisms, their characteristics, and their implications in various fields.

At its core, "Pasteurelleae" represents a clade of gram-negative bacteria that share certain morphological and biochemical traits. These bacteria are primarily known for their rod-shaped appearance and are often studied due to their association with infectious diseases in animals and humans. This group includes important genera such as:

• Pasteurella: This genus includes species like Pasteurella multocida, known to cause respiratory infections in animals and humans.
• Actinobacillus: Bacteria from this genus are often involved in infections in livestock, particularly swine, leading to significant economic implications.
• Haemophilus: Some species within this genus can cause respiratory diseases in both humans and animals.

The significance of the Pasteurelleae tribe extends beyond their biological characteristics. They have been associated with various zoonotic diseases, meaning they can be transmitted from animals to humans. For instance, Pasteurella multocida is known to cause infections following bites or scratches from cats and dogs. Understanding these bacteria is crucial for both public health surveillance and the management of animal health.

In addition to their clinical importance, the study of Pasteurelleae can provide insights into microbial ecology and evolution. Research into their genetic makeup helps reveal how these organisms interact with their hosts and adapt to different environments. This understanding is vital for developing vaccines and treatments for diseases caused by these bacteria.

In summary, "Pasteurelleae" refers to a significant group of gram-negative bacteria known for their pathogenic potential in both animals and humans. Their role in public health and veterinary medicine makes understanding this term essential for professionals in these fields. Further research into the Pasteurelleae group continues to shed light on their biological behaviors, interactions, and implications for health and disease management.
