A group of diseases caused by Rickettsia bacteria.

A bacteria belonging to the Rickettsiaceae family, known for causing various diseases.

Inflammation of blood vessels, often caused by Rickettsia infections.

A serious form of typhus caused by Rickettsia prowazekii, often spread by lice.

A subspecies of Treponema pallidum that causes yaws, a tropical disease characterized by skin lesions that start as a primary ulcer and spread to other parts of the body.

A tropical infection caused by Treponema pallidum subspecies pertenue.

A superficial skin infection caused by Treponema carateum, characterized by depigmentation and scarring of the skin.

A bacterial infection caused by Bartonella quintana, typically spread through the bite of an infected louse.

A genus of bacteria that includes the species Leptospira interrogans, which causes leptospirosis.

A bacterial infection caused by Bartonella henselae, commonly transmitted through a cat's scratch or bite.

A zoonotic disease caused by Leptospira interrogans, transmitted through contact with contaminated animal urine.

A type of bacterial infection that affects blood vessels, particularly in individuals with compromised immune systems.

A genus of bacteria that includes Borrelia burgdorferi, the causative agent of Lyme disease

A group of bacteria that are obligate intracellular parasites, meaning they require a host cell to survive and reproduce.

A tick-borne disease caused by Borrelia burgdorferi, characterized by a distinctive rash, fever, and potential complications affecting the joints, heart, and nervous system.

The metabolically inactive form of Chlamydia that is released from infected host cells and is capable of infecting new cells.

The actively dividing and non-infectious form of Chlamydia that grows inside host cell vacuoles.

A type of Borrelia causing a relapsing fever that is transmitted by ticks.

A protein found on the outer membrane of Chlamydia, which is important for the immune response to the bacteria.

A gram-negative spirochete, which means it has a spiral shape and does not stain purple with Gram staining.

A type of fever caused by Borrelia hermsii, characterized by recurrent high fevers and chills.

A process where Chlamydia inhibits the fusion of lysosomes with the vacuole where it resides, protecting itself from destruction.

A chlamydia-related protein that controls the timing of cell death, delaying it during the growth phase but triggering it at the release stage.

A membrane-bound vesicle created by Chlamydia within the host cell, serving as a protected environment for its replication and growth.

Spiral-shaped bacteria that are elongated, motile (able to move), and flexible. They have characteristic endoflagella, which are flagella-like structures that wrap around the cell and help with movement.
