Burkholderia mallei is the causative agent of glanders, a disease primarily affecting horses but can infect humans.

Pseudomonas aeruginosa is known for producing a blue-green pigment called pyocyanin.

Pseudomonas aeruginosa is primarily transmitted through direct contact with contaminated surfaces, especially in healthcare environments.

Pseudomonas aeruginosa typically appears as green colonies on culture media and has a characteristic fruity odor.

Pseudomonas aeruginosa can cause a wide range of infections, including pneumonia, urinary tract infections, and sepsis in immunocompromised patients.

Vancomycin is often ineffective against Pseudomonas aeruginosa, as it is primarily effective against Gram-positive bacteria.

Burkholderia cepacia is most commonly associated with respiratory infections, particularly in patients with cystic fibrosis.

Cystic fibrosis is a common risk factor for Burkholderia cepacia infection due to the compromised lung function.

Burkholderia pseudomallei infection is often characterized by abscess formation, particularly in the lungs and other organs.
