Shewanella putrefaciens: a rare cause of purulent otorrhoea
More LessShewanella putrefaciens is a Gram-negative, non-fermenting, motile and oxidase-positive bacillus. Its incrimination in human pathology is very rare, although there has been a resurgence in Shewanella infections in recent years. We report the first case in Morocco of a purulent otorrhoea caused by S. putrefaciens , resistant to conventional treatment, occurring in a 25-year-old female, afebrile, without deterioration of the general state and possibly acquired during sea bathing. We also describe the bacteriological characteristics of and antibiotic susceptibility results for the isolate.

Infective endocarditis due to Haemophilus sputorum
More LessIntroduction. Haemophilus species are gram-negative, non-motile, facultative anaerobic coccobacilli in the larger family of Pasteurellaceae . Implicated in a variety of human diseases, Haemophilus species are also included in the ‘HACEK’ group of organisms, which are fastidious gram-negative bacteria, a well-described but uncommon cause of endocarditis. Among the Haemophilus species responsible for endocarditis, Haemophilus parainfluenzae is the most frequently isolated. However, novel species of Haemophilus have recently been described, and their clinical significance remains uncertain.
Case presentation. A 35-year-old man was admitted to the hospital after presenting with a 3 month history of nightly fevers, night sweats and unintentional weight loss, with a new murmur detected on cardiac auscultation. Blood cultures returned positive for Haemophilus sputorum identified by matrix assisted laser desorption ionization – time of flight MS, and confirmed with whole genome sequencing. Echocardiography revealed the presence of an aortic valve vegetation, with aortic and mitral valve leaflet perforations. He was successfully treated with surgical bioprosthetic valve replacements and pathogen-directed antibiotics without complications.
Conclusion. We describe a case of infective endocarditis due to H. sputorum , a newly identified Haemophilus species, which to the best of our knowledge has yet to be reported, and discuss the available literature regarding this organism.

A rare case of neonatal meningoencephalitis from Paenibacillus thiaminolyticus
More LessPaenibacillus infections can be life threatening and are being reported with increasing incidence. There are only a few case reports of infections and are mainly described in patients who are immunocompromised, injection drug users, or those with prosthetic devices. Due to improved testing and identification, it appears that these infections may not be as rare as once perceived. We present a case of a 16-day-old term neonate who presented with status epilepticus and was found to have Paenibacillus thiaminolyticus meningoencephalitis. The patient was successfully treated with a combination of ampicillin and ceftazidime then meropenem. To our knowledge, this is the first reported case of an infant in the United States who survived this serious invasive infection. We also present an option for therapy given the difficulty treating invasive intracranial infections.

Actinomyces and Shewanella algae complicated paediatric mastoiditis: a case report of a multidisciplinary approach
Cerebral venous sinus thrombosis in children is a rare complication of acute mastoiditis that can potentially be fatal. Clinical expertise is essential for early diagnosis and management due to its subtle course. We present the first known case of paediatric acute mastoiditis with venous sinus thrombosis caused by Shewanella algae and Actinomyces europaeus .
A 17-year-old male presented clinical signs of right acute otitis media and mastoiditis. Brain computed tomography showed mastoid opacification, cerebral sinus thrombosis and an extradural collection. Microbiology revealed the presence of S. algae and A. europaeus . A multidisciplinary approach combining medical and surgical treatment allowed the patient to make a full recovery.

MRSA in the bursa: an unusual complication of MRSA bacteremia causing bilateral acromioclavicular septic arthritis
More LessBackground. Bacteraemia is known to cause serious complications including metastatic infections such as infective endocarditis, vertebral osteomyelitis, iliopsosas abscesses and septic arthritis. Bilateral septic arthritis, however, is a rare medical emergency with limited previous reports. Staphylococcus species are the most common organisms identified as a result of suspected haematogenous spread from bacteraemia, direct inoculation or translocation from adjacent tissues. While unilateral septic arthritis due to intravenous drug use is a common phenomenon warranting prompt treatment to preserve mobility, function and quality of life, cases of bilateral infections are exceedingly rare. Furthermore, infections involving the acromioclavicular joint are not commonly documented in the literature.
Case Presentation. We present a case of a 41-year-old female with a history of intravenous drug use who presented with low back pain and was found to have methicillin-resistant Staphylococcus aureus bacteraemia that was complicated with metastatic infections causing bilateral acromioclavicular joint septic arthritis.
Conclusions. Metastatic infections from bacteraemia are serious complications that can lead to septic arthritis. Though septic arthritis is best known in previous case reports to present as a unilateral infection, rare cases of bilateral involvement warrant further consideration. A thorough history and physical examination evaluating all joints can identify such atypical presentations. Septic arthritis remains a medical emergency, and it is imperative that clinicians recognize unusual presentations to avoid delays in treatment that can lead to detrimental impacts to quality of life.
