The word Pasteurella is spelled with a stress on the second syllable, /ˌpæstəˈrɛlə/. The first syllable is pronounced with a schwa /ə/ sound, followed by the consonant cluster 'st'. The next syllable has the primary stress, with the vowel sound 'ɛ' and the consonant 'r'. The final syllable has the 'l' and 'ə' sounds. Pasteurella is a genus of bacteria that can cause infections in both humans and animals. Proper spelling and accurate pronunciation of scientific names are essential for clear and effective communication in the field of microbiology.
Pasteurella is a genus of gram-negative, non-motile, rod-shaped bacteria belonging to the family Pasteurellaceae, named after the French scientist Louis Pasteur. This genus encompasses several species that primarily exist as commensals or pathogens in animals, including mammals and birds. Pasteurella species are known for their role in causing various infections, especially respiratory-related illnesses in animals and humans.
These bacteria are typically facultative anaerobes, capable of both aerobic and anaerobic growth. They typically inhabit the mucous membranes of the upper respiratory tract and can cause a range of diseases, including pneumonia, otitis media, sinusitis, and systemic infections such as septicemia. In humans, Pasteurella infections are commonly acquired through animal bites or scratches, particularly from cats and dogs. These infections can lead to localized cellulitis, abscess formation, and lymphadenitis.
Pasteurella bacteria are often susceptible to many common antibiotics, including beta-lactam agents such as penicillin. However, some species have developed resistance to certain antibiotics, making treatment more challenging. Accurate diagnosis of Pasteurella infections is crucial for appropriate treatment and management.
While Pasteurella primarily affects animals, it has the potential to cause significant health problems in humans, particularly those with compromised immune systems or underlying respiratory conditions. Proper hygiene and cautious handling of animals, especially those with bite or scratch injuries, are key preventive measures to reduce the risk of Pasteurella infections.

The word "Pasteurella" is derived from the surname of French chemist and microbiologist, Louis Pasteur. Pasteurella is a genus of bacteria that was named in honor of his significant contributions to science and medicine. Louis Pasteur is renowned for his work in the field of microbiology, particularly regarding the understanding and prevention of diseases.
