Abstract
Aerococcus urinae is a Gram-positive, catalase-negative coccus, rarely responsible for urinary tract infections and seldom described for musculoskeletal infections like spondylodiscitis. An 86-year-old man presented to our hospital for groin pain without fever. Pelvic CT-guided biopsy revealed an A. urinae pubic symphysis osteomyelitis. He received a treatment by amoxicillin per os for six weeks, and did not need any surgery. An eight -month- follow-up showed a favorable evolution. Pubic symphysis infection can be induced by a wide variety of pathogens, and may have very different clinical presentations. Some authors recommend systematic surgery, but in case of susceptible pathogen associated with a low level of joint destruction, medical treatment alone should be sufficient to cure and make surgery unnecessary.

Abstract
Aerococcus urinae is a gram-positive organism frequently found in the urinary tract. It is often mistaken for Streptococcus and Enterococcus based on its appearance. It commonly causes urinary tract infections but has rarely been associated with fatal infective endocarditis and sepsis. We present a case of Aerococcus urinae infective endocarditis and discuss echocardiographic imaging findings and management approach.

Abstract
Elderly patients with underlying urological disease have a greater risk of urinary tract infections due to uncommon pathogens. The disease caused by Aerococcus has been underestimated, but mass spectrometry could be a simple method for identifying this pathogen. In this study, we report 2 cases of urinary tract infection by Aerococcus sanguinicola. A descriptive clinical-microbiological study was conducted on the presence of A. sanguinicola causing urinary tract infections. The presence of A. sanguinicola occurred in elderly patients with previous urological disease and a significant count in urine obtained through bladder catheterisation. Correct identification was achieved through mass spectrometry, and the clinical outcome of administering amoxicillin and cefuroxime was satisfactory. In this study, we also report the pathogenic capacity of A. sanguinicola. When there is a significant number of alpha-haemolytic microorganisms in the urine cultures, A. sanguinicola should be ruled out before reporting a result as urogenital microbiota.

Abstract
Objective To determine the incidence, types of organisms and resistance patterns involved in early-onset neonatal sepsis in Canada. Study design Early-onset neonatal sepsis cases were identified through the Canadian Paediatric Surveillance Program. Neonates were excluded if they were asymptomatic or if intracranial procedures preceded a positive cerebrospinal fluid culture. Results One hundred and twenty-seven cases were identified (0.17 cases per 1000 live births). Group B Streptococcus accounted for 41.7%, Escherichia coli for 35.4%. Antibiotic resistance was present in 33.9% of all cases. 55.6% of E coli cases were resistant, most commonly to ampicillin. Infecting organism species were associated with gestational age, being very low birth weight, time at sepsis presentation, maternal antibiotic prophylaxis and rupture of membranes lasting over 18 hours. Group B Streptococcus was most common in term and E coli in preterm neonates. Twenty-two per cent of E coli cases presented after 48 hours, compared to 6% of Group B Streptococcus cases. Conclusion We identify a lower rate of early-onset neonatal sepsis than historically suggested, with differing dominant organisms based on gestational ages and other factors, as well as high rates of resistance especially among E coli cases.

Abstract
Aerococci are Gram-positive cocci with colony morphology similar to viridans streptococci. Most often these isolates in clinical samples are misidentified and considered insignificant. However, with the use newer techniques like Matrix-Assisted Laser Desorption Ionization Time-of-Flight Mass-Spectrometry (MALDI-TOF MS), aerococci have been recognized as significant human pathogens capable of causing a diverse spectrum of infections. Among the different species of aerococci, Aerococcus urinae is the most common agent causing Urinary Tract Infection (UTI) followed by A. sanguinocola. Aerococcus viridans (A. viridans) have been reported rarely in urinary tract infections. The antimicrobial resistance in aerococci in terms of its intrinsic resistance and evolving resistance to penicillin and vancomycin has raised the concern for better understanding of this pathogen. We recently encountered two cases of nosocomial UTI caused by A. viridans which are being reported here.
