| Case title [Ref] | Characteristics |
|---|---|
| Epidural abscess due to []12 | A 67-year-old male presented with a 48-hour history of fever, chills, and low back pain. Physical examination revealed no significant findings. His medical history included cohabitation with domestic animals but no history of bites or scratches. Laboratory findings showed leukocytosis (15 100/mm) with neutrophilia. Microbiological analysis identified [] sensitive to various antibiotics. MRI revealed an anterior epidural abscess at the L4–L5 level involving surrounding structures. Treatment with ciprofloxacin for 4 weeks resulted in resolution of the abscess and symptoms |
| Osteomyelitis of the heel with : A case report []13 | A 31-year-old female nurse presented with a history of a heel injury followed by chronic osteomyelitis. Physical examination, imaging, and bacterial culture confirmed the diagnosis of []. Surgical excision and antibiotic therapy were initiated, resulting in complete healing with no recurrence |
| Bilateral interstitial pneumonia in a patient with AIDS []14 | A 27-year-old male patient with HIV presented with fever and respiratory symptoms. He reported owning several dogs, which frequently licked his face.Bone marrow biopsy revealed persistent leishmaniasis, and treatment with pentavalent antimony led to immediate improvement and resolution of fever. However, fever and respiratory symptoms recurred 1 week later. Bronchoscopy revealed gram-negative bacilli, later identified as []. Treatment with penicillin resulted in symptom resolution |
| Septicemia due to : 16S rRNA sequencing for diagnosis confirmation []15 | A 72-year-old female patient was admitted with an 18-day history of fever, chills, night sweats, and asthenia. Her medical history included mitral stenosis due to rheumatic fever, valve replacement with a Saint-Jude prosthesis, and permanent pacemaker implantation for sick sinus syndrome. On admission, there were no cutaneous lesions or signs of scratches or bites.Laboratory findings showed leukocytosis (18 800/mm) with neutrophilia. Blood cultures confirmed [], with diagnosis validated by 16S rRNA gene sequencing. Treatment details were not provided |
| Colonization of the respiratory tract by []16 | A 58-year-old female patient with severe emphysema presented with purulent secretion from her tracheostomy and erythema around the site. Her medical history included alpha-1 antitrypsin deficiency with a homozygous Z allele. Laboratory findings showed leukocytosis (15 300/mm) with a predominance of polymorphonuclear cells.Culture on chocolate agar supplemented with Polyvitex revealed [], which was sensitive to various antibiotics. The diagnosis was confirmed using the API 20E system (bioMérieux) |
| First reported case of tricuspid valve endocarditis []17 | A 72-year-old female patient was admitted with an 18-day history of fever, chills, night sweats, and asthenia. Her medical history included mitral stenosis due to rheumatic fever, valve replacement with a Saint-Jude prosthesis, and permanent pacemaker implantation for sick sinus syndrome. On admission, there were no cutaneous lesions or signs of scratches or bites.Laboratory findings showed leukocytosis (18 800/mm) with neutrophilia. Blood cultures confirmed [], with diagnosis validated by 16S rRNA gene sequencing. Treatment details were not provided |
