Aerococcus urinae is often misclassified in routine diagnostic laboratories. A. urinae shares features with staphylococci, streptococci and enterococci as the bacterium grows in clusters, displays a-haemolysis when grown on blood agar, and is resistant to sulphonamide. We report here, a case study of A. urinae, which initially was misdiagnosed. Identification and susceptibility testing were per...

Osteomyelitis is a challenging disease for clinicians and patients despite the many advances in diagnosis and treatment. Chronic suppurative osteomyelitis (CSO) of the mandible is often considered difficult to treat. Several authors conclude that CSO can be treated successfully by a combination of intravenous antimicrobial therapy and surgery consisting of sequestrectomy or decortication, the r...

Post-traumatic pulmonary pseudocyst is an uncommon cavitary lesion of the lung, which generally develops after blunt chest trauma. We saw a 22-year-old man with chest trauma, hemopneumothorax, and hemoptysis, on the day he fell from an electrical pylon. Intubation in the emergency department was followed by 4 days of mechanical ventilation. Computed tomogram found a post-traumatic pulmonary pse...

Two hydroquinone derivatives were prepared and their antimicrobial activity evaluated. Their minimum inhibitory concentrations (MICs) were determined using a broth dilution method. Gentamycin and ciprofloxacin were used as reference antibiotics. The antimicrobial activity of 4-(benzyloxy)phenol (monobenzone) was also evaluated based on its structural similarity to the new compounds; activity wa...

In this study, the patterns of resistance to 10 antibiotics by 730 Vibrio cholerae non-O1 and non-O139 species isolated from both environmental and seafood samples were investigated. Susceptibility to different antimicrobial agents was assessed by the disc diffusion technique. The frequencies of resistance to 10 antimicrobial agents--ampicillin, chloramphenicol, bacitracin, erythromycin, gentam...

To shed light on the role of Streptococcus equisimilis (SE) in the pathogenesis of intervertebral disc infection, we report here a case of lumbar spondylodiscitis in a 37-year-old male caused by SE, with identification of this strain by cultures from L4-L5 lumbar disc biopsy. Intravenous therapy with penicillin and gentamycin combined with immobilization resulted in a rapid and complete recover...

A 54-year old-man presented with a two-day history of severe pain and decreased vision. Examination revealed a corneal ulcer associated with a loose suture from cataract surgery done approximately two years ago. The suture was removed and the patient was started on topic antibiotic treatment with cefazolin and gentamycin. Cultures revealed methicillin-resistant Staphylococcus aureus (MRSA). The...

Dear Editor, A 39-year-old man with stable aortic regurgitation secondary to congenital bicuspid aortic valve was diagnosed with Streptococcus mitis infective endocarditis with low minimum inhibitory concentration to penicillin. Initial transoesophageal echocardiography demonstrated aortic root oedema with vegetations seen on the aortic valve. Despite improving clinical parameters on intravenou...
