title: Polyarticular septic arthritis caused by non-encapsulated haemophilus influenzae biotype I in a rheumatic adult.
abstract: Haemophilus influenzae causes less than 1% of all septic arthritis cases in adults. Most often serotype b is responsible. Here we describe a rare case of non-encapsulated H. influenzae-induced polyarticular septic arthritis in a rheumatic patient with no other infectious focus.
