EPIDEMIOLOGY AND PATHOGENESIS OF STAPHYLOCOCCAL INFECTION I. AN EXPERr~c~.NTALLY INDUCED ATTENUATED STAPHYLOCOCCAL INFECTION IN GUINXA PIGS AND ITS MODIFICATION BY TETRACYCLINE*

Infection with "pathogenic" microorganisms but without clinically apparent disease has been variously defined as latent, subclinical, dormant , occult, and inapparent. These terms are employed with varying meanings by clinicians, veterinarians, phytopathologists, and other biologists. For the sake of greater consistency, however, three general categories of infections without apparent disease have been proposed, defined, and broadly grouped under the te rm "a t tenua ted infection" (1). These three categories are the carrier state, microbial persistence, and latent infection.
