| rat-bite f. |
either of two clinically similar but etiologically distinct acute infectious diseases, usually transmitted through the bite of a rat: (1) The bacillary form is caused by Streptobacillus moniliformis and has a latent period of about a week, during which the initial wound heals without inflammation; however, later the bite site becomes inflamed and indurated, and this is followed by adenitis, chills, vomiting, headache, high fever, morbilliform eruption, especially on the hands and feet, and polyarthritis that is often severe. This form may also be caused by ingestion of contaminated raw milk or its products (Haverhill fever), in which case there is no initial wound and the first symptoms are systemic. (2) The spirillary form (called also sodoku) is caused by Spirillum minus and has a latent period of usually more than ten days. Inflammation recurs at the primary wound site; the rash is less evident than in the bacillary form; arthritis is rare; and the fever is commonly of the relapsing type.
