Glaesserella is a genus of Gram-negative bacteria in the family Pasteurellaceae. Members of this genus are primarily associated with pigs and include pathogens of veterinary importance.

Taxonomy

[edit]

The genus was established in 2020 following phylogenomic analyses that reclassified species previously placed in the genus Haemophilus. The type species is Glaesserella parasuis, formerly known as Haemophilus parasuis.[1]

Etymology

[edit]

The name Glaesserella honors Karl Glässer, a German veterinarian who first described Glässer’s disease in pigs in 1906. The suffix "-ella" is a diminutive commonly used in bacterial genus names.[2]

Species

[edit]

Recognized species within the genus include:

Clinical significance

[edit]

Glaesserella parasuis is the causative agent of Glässer’s disease, a condition in pigs characterized by polyserositis, arthritis, meningitis, and pneumonia. It mainly affects weaned piglets and can result in significant economic losses in swine production.[3]

Identification

[edit]

Species of Glaesserella can be identified through biochemical testing and molecular methods such as polymerase chain reaction (PCR) assays and 16S rRNA gene sequencing.[4]
