Final answer:
Bacillary angiomatosus is associated with infection by Bartonella henselae.
Step-by-step explanation:
Bacillary angiomatosis is a bacterial infection caused by Bartonella henselae or Bartonella quintana. These bacteria are gram-negative bacilli that can infect humans, causing a vascular proliferative disease characterized by the formation of vascular lesions. Bacillary angiomatosis is most commonly associated with immunocompromised individuals, such as those with HIV/AIDS, but it can also occur in individuals with intact immune systems.
Bacillary angiomatosus is associated with infection by Bartonella henselae, which is a gram-negative bacterium.
