Septic arthritis due to Haemophilus influenzae serotype a in the post-vaccination era in Brazil

Septic Arthritis and Hemarthroses Caused by Haemophilus influenzae Serotype A in Children

“… 12 More recently, the first case of Hia septic arthritis in Australia and the first case in Brazil were reported. 13 , 14 In both cases, Hia septic arthritis seems to respond well to antibacterial therapy and does not seem to leave behind any sequelae (as in our patient). Cases reported so far have been summarized below ( Table 1 ).…”

Haemophilus influenzae serotype a septic arthritis in an immunized central Australian indigenous child

“…We have found one case report of septic arthritis caused by Hia in Brazil. 6 Studies from the North American Arctic indigenous peoples have found an increase in the incidence of invasive Hia since the introduction of the Hib vaccine coinciding with a fall in Hib incidence. 7,8 These studies also report Hia septic arthritis.…”

Characteristics of invasive Haemophilus influenzae serotype a (Hia) from Nunavik, Canada and comparison with Hia strains in other North American Arctic regions

“…19 Biotype III Hia has also been described from Brazil. 20,21 Since the microbiology of the Hia isolates from Nunavik has not been described, this study, therefore, describes the characteristics of the invasive Hia isolates from Nunavik and compares them with previous data on Hia isolates from Nunavut 15 and Alaska. 13 Our aim is to find out if a single clone or multiple clones of Hia are causing invasive disease in the North American Arctic.…”
