title: Experimental induction of cervical lymphadenitis in guinea-pigs with group C streptococci.
abstract: Streptococcal lymphadenitis with macroscopic abscesses was induced in guinea-pigs when an isolate of Lancefield's group C streptococci of guinea-pig origin was sprayed orally. The disease was also produced in guinea-pigs when another isolate was injected sublingually but not when it was sprayed orally. Treatment with prednisolone did not increase the susceptibility to the latter isolant when sprayed orally. Abscesses could not be induced in the cervical lymph nodes of guinea-pigs exposed by injecting group E streptococci sublingually, although the organism was isolated from the cervical lymph nodes 2 days after inoculation. Neither could abscesses be induced by injecting these streptococci sublingually in guinea-pigs treated with prednisolone.
