The previously established model for determining dermal granulomatous reactivity of Q fever vaccines uses footpad injections to sensitize Hartley guinea pigs. We describe a substantial refinement to that model by substituting an alternate injection route and replacing the model with the hairless Hartley guinea pig. The experimental design incorporates a matrix of various antigen and adjuvant combinations administered by subcutaneous (SC) and intradermal routes of administration. The two Coxiella burnetii antigens evaluated were phase-I whole-cell vaccine (WCV) and phase-I chloroform-methanol residue vaccine. The adjuvants used were complete Freund's (CFA), incomplete Freund's, and RIBI's De-Tox. Phase-I C. burnetii WCV in CFA administered SC provided the most efficacious regimen evaluated for sensitizing hairless guinea pigs. The establishment of this animal model allows evaluation of candidate Q fever vaccines in a more humane model than that previously available.

D007114	Immunization	Deliberate stimulation of the host's immune response. ACTIVE IMMUNIZATION involves administration of ANTIGENS or IMMUNOLOGIC ADJUVANTS. PASSIVE IMMUNIZATION involves administration of IMMUNE SERA or LYMPHOCYTES or their extracts (e.g., transfer factor, immune RNA) or transplantation of immunocompetent cell producing tissue (thymus or bone marrow).

D007700	Kinetics	The rate dynamics in chemical or physical systems.
D011778	Q Fever	An acute infectious disease caused by COXIELLA BURNETII. It is characterized by a sudden onset of FEVER; HEADACHE; malaise; and weakness. In humans, it is commonly contracted by inhalation of infected dusts derived from infected domestic animals (ANIMALS, DOMESTIC).

D000276	Adjuvants, Immunologic	Substances that augment, stimulate, activate, potentiate, or modulate the immune response at either the cellular or humoral level. The classical agents (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity.
