BACKGROUND: Aggregatibacter aphrophilus, a commensal of the oro-pharyngeal flora and member of the HACEK group of organisms, is an uncommonly encountered clinical pathogen. It has already been described as the causative agent of brain abscesses, empyema, meningitis, sinusitis, otitis media, bacteriemia, pneumonia, osteomyelitis, peritonitis, endocarditis and wound infections. Herein we report the first case of bartholinitis due to A. aphrophilus. CASE PRESENTATION: A 33-year-old woman was admitted for a 3-day genital pain without fever and urinary functional signs...

Brain abscess is a rare but potentially lethal infection of brain parenchyma, requiring prompt surgical intervention and high-dose antibiotic therapy. Brain abscess is a known complication of surgically treated intracerebral hemorrhage (ICH), but it is exceptionally rare that it occurs at the same site of a nonoperated ICH. Such cases may result from hematogenous spread from distant foci (pneumonia, infectious endocarditis) or contiguous sites. Herein, the authors report a case of 75-year-old woman presenting with a brain abscess 6 weeks after a nonoperated ICH...

Central nervous system (CNS) infections, including meningitis, encephalitis, and brain abscess, are rare but time-sensitive emergency department (ED) diagnoses. Patients with CNS infection can present to the ED with nonspecific signs and symptoms, including headache, fever, altered mental status, and behavioral changes. Neuroimaging and CSF fluid analysis can appear benign early in the course of disease. Delaying therapy negatively impacts outcomes, particularly with bacterial meningitis and herpes simplex virus encephalitis...

Phaeohyphomycosis is a term used to describe infections caused by dematiaceous fungi, i.e. fungi which contain melanin in their cell wall. Cladophialophora bantiana has been implicated to cause brain abscess in immunocompromised patients. Infection caused by Cladophialophora bantiana in an immunocompetent host is relatively rare. Surgical site infection at abdominal subcutaneous tissue caused by Cladophialophora bantiana was noted in this case, which was rarely reported.

BACKGROUND: Mycoplasma hominis, a well known cause of neonatal infection, has been reported as a pathogen in urogenital infections in adults; however, central nervous system (CNS) infections are rare. We report here the first case of M. hominis meningitis in China, post neurosurgical treatment for an intracerebral haemorrhage in a 71-year-old male. CASE PRESENTATION: We describe a 71-year-old man who developed M. hominis meningitis after neurosurgical treatment and was successfully treated with combined azithromycin and minocycline therapy of 2 weeks duration, despite delayed treatment because the Gram stain of cerebrospinal fluid (CSF) yielded no visible organisms...

We report a case of intratumoral brain abscess due to Bacillus cereus in an adult male patient, which was managed successfully with excision of lesion and piperacillin-tazobactam for the duration of 5 weeks. To the best of our knowledge, this is a first case report of B. cereus infection leading to intratumoral brain abscess in a patient with a history of steroid administration by the intravenous route.

Nocardiosis is a rare bacterial infection occurring mainly in patients with deficient cell-mediated immunity. Although disseminated nocardiosis after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a rare complication, it is associated with high mortality. Moreover, after allo-HSCT, nocardiosis may be mistaken for other bacterial or fungal infections because clinical and radiographic findings of pulmonary, cerebral, and cutaneous nocardiosis lesions are non-specific. Here, we report a case of disseminated nocardiosis (caused by Nocardia abscessus) with skin, pulmonary, liver, lymph node, and multiple brain abscesses in a patient after allo-HSCT...

Previous in vitro data showed that was inhibited by limonene. We further evaluated effects of limonene on growth of in vitro as well as on ruminal concentrations of in vivo. With in vitro cultivation in anaerobic brain-heart infusion broth, limonene decreased growth of . Thymol also reduced growth of , but it was less effective than limonene. Tylosin effectively reduced growth of in vitro. Although the response over fermentation times and concentrations of antimicrobials differed somewhat between tylosin and limonene, the 2 antimicrobial agents yielded similar inhibitory effects on growth of at concentrations ranging from 6 to 24 mg/L...

Nocardial brain abscesses are uncommon and rarely occur in patients without predisposing factors. They may be mistaken for gliomas or necrotic metastases, and surgical intervention may be required to make the diagnosis. We report the first case of Nocardia farcinica cerebellar abscess in a patient without immunosuppression. He presented to us with headache and instability beginning a week before. Brain magnetic resonance imaging (MRI) revealed a cystic lesion located at the right cerebellar hemisphere, hypointense in T1 and hyperintense in T2, with a fine wall that enhanced after injection of gadolinium...

This article describes a patient whose intracerebral MRSA may have been caused by a spider bite to the thigh 2 months earlier. The patient's headache, nausea, and vomiting initially were thought to be caused by a high-grade glioma. Most brain abscesses have otogenic sources and are not from distant hematogenous spread. Although systemic antibiotics help with symptomatology, surgical eradication (when feasible) followed by IV antibiotics, provides definitive treatment.

Intracranial mucormycosis is a very unusual presentation of an infection after a depressed skull fracture due to an assault. Only sporadic cases have been reported in the literature previously. A 30-year-old male with a traumatic brain injury following an assault, status-post debridement and elevation of a depressed skull fracture, was discharged home several weeks postoperatively. A CT scan of the head with contrast was obtained due to mental status changes and revealed an enhancing ring-shaped lesion in the right frontal lobe consistent with a brain abscess...

Intracranial complications of chronic otitis media have been on the decline with advent of antibiotics. Septic thrombosis of the sigmoid sinus is rarer compared to commoner complications such as otogenic brain abscesses and meningitis. This patient presented with recurrent infection after left mastoidectomy secondary to cholesteatoma and a contralateral internal jugular vein thrombosis with parapharyngeal abscess, which was drained. He recovered well postoperatively with antibiotics.

Abiotrophia defectiva, a nutritionally variant streptococci can cause bacteremia, brain abscess, septic arthritis and in rare cases, infective endocarditis, which accounts for 5-6% of all cases. A. defectiva is characteristically difficult to diagnose and the mortality, morbidity and complication rates are high. Here, we discuss a case of infective endocarditis caused by A. defectiva. A 62-year-old female had previously undergone prosthetic valve replacement 6 years prior to admission. She developed infective endocarditis after tooth extraction...

HISTORY AND ADMISSION FINDINGS: A 55-year old man suffers from progressive, distinctive dyspnoea and physical weakness since 5 days. Due to ST-segment changes in the ECG and a positive troponin-test, the primary care physician initiates an hospitalization. INVESTIGATIONS: After admission, the laboratory tests confirm the elevated troponin-values, and show additionally elevated pro-brain-natriuric-peptide-values. The coronary angiography presents a highly reduced left ventricular function, an aortic insufficiency III° and a coronary heart disease...

INTRODUCTION: The Streptococcus anginosus group of bacteria are low-virulence bacteria existing as commensals in the oral flora and gastrointestinal tracts of humans. S. anginosus may spread to the blood in individuals with poor oral hygiene in cases of oral infections, such as gingivitis and tooth abscesses, that develop following the loss of mucosal unity. This may lead to infections in the whole body, primarily as brain and liver abscesses. CASE PRESENTATION: A 32-year-old male patient presented with complaints of nausea, vomiting, and diffuse abdominal pain...

Nocardia farcinica is a gram-positive, partially acid-fast, methenamine silver-positive aerobic actinomycete that is infrequently associated with nocardiosis. The relative frequency of Nocardia farcinica isolates in nocardiosis is unknown but thought to be under diagnosis. It is increasingly been recognized in immunocompetent patients. We report a case of disseminated Nocardia farcinica causing brain abscess in 55 year old immunocompetent man who was successfully treated with long term antibiotics. The present report illustrates that early detection and treatment of disseminated Nocardia farcinica can lead to a good outcome...
