Abstract:
A total of 159 patients with Streptococcus milleri (S. milleri) infection were diagnosed in our hospital between January 2014 and January 2019. The demographic data, underlying diseases, infection sites, laboratory tests, and prognosis of patients were retrospectively analyzed; the clinical and microbiological data were compared among different age groups. Of the 159 patients there were 103 were males and 56 females; there were 19 patients aged<18 years [(8.1±5.3) years], 113 patients aged ≥18 and < 65 years [(45.5±13.1) years] and 27 patients aged ≥65 years[(74.7±8.6) years]. The incidence peaked in the 34-55 year age group (50 cases, 31.4%). Streptococcus anginosus was identified in 97 cases (61.0%), Streptococcus constellatus in 55 patients (34.6%) and Streptococcus intermedius in 7 cases (4.4%). The abdomen (44 cases, 27.7%) and the chest (19 cases, 11.9%) were the main involving sites. For patients younger than 18 years and those aged ≥18 and<65 years, suppurative appendicitis was the most common condition[12 cases(12/19) and 21 cases(18.6%), respectively]; while in patients aged ≥65 years, chest infection ranked the first (9 cases, 33.3%). All 159 patients were treated with anti-infection therapy alone or anti-infection and invasive procedures with a favorable prognosis, 2 patients died with a overall fatality rate of 1.3%.
