RESUMO

We present a case of endocarditis with embolic stroke and digital infarction due to the recently renamed Aggregatibacter aphrophilus. The isolation and identification of this organism can be problematic but was achieved in this case using both older phenotypic and newer genotypic methods. A benign tongue lesion is suggested as the likely portal of entry for this oropharyngeal organism. The patient made a good recovery with six weeks of intravenous ceftriaxone but will need cardiac valvular surgery at some point in the future.

RESUMO

Human diseases caused by Haemophilus paraphrophilus (H.paraphrophilus) are unusual. The following case report describes a 67-year-old man who presented with pain and swelling of the right side of the face. Fine needle aspiration suggested a parotid gland abscess. Microbiological studies identified H.paraphrophilus. This is the first time a parotid abscess has been found to be caused by this organism.

RESUMO

OBJECTIVES: Acute appendicitis is a common surgical emergency. The etiology and pathophysiology of appendicitis have been well investigated. Aggregatibacter aphrophilus is a fastidious gram-negative coccobacilli. Detection of this organism in clinical samples and its differentiation from Haemophilus aphrophilus or from Aggregatibacter actinomycetemcomitans in routine microbiology settings could be difficult. METHODS: In this rare case, we report the isolation of Aggregatibacter aphrophilus from the appendix of a 14-year-old boy presented with acute appendicitis. The genotypic method using 16S rRNA sequencing was used for identification of the organism at species level. CONCLUSION: This case highlights the importance of detecting fastidious and rare microorganisms such as Aggregatibacter aphrophilus that could be associated with acute appendicitis.

RESUMO

Patients with alcoholic cirrhosis who have ascites have a high risk of developing spontaneous bacterial peritonitis (SBP). The authors report a case of SBP caused by Haemophilus paraphrophilus, the first-reported SBP in literature with this pathogen. Later on, the patient also developed tuberculous (TB) peritonitis associated with thoracic Pott's disease, a combination never reported before. The diagnoses were confirmed by positive mycobacterium cultures of both omental tissues and vertebral tissues. This report also illustrates prominent computed tomography findings of TB peritonitis and magnetic resonance imaging of spinal cord compression of Pott's disease. Tuberculosis is a treatable and curable disease and should be considered as a potential offending pathogen on differential diagnosis in SBP of alcoholic cirrhotic patients. Timely biopsy and surgical intervention with these kinds of TB are needed to lead early diagnosis and result in an excellent outcome.

RESUMO

Aggregatibacter aphrophilus was previously known as Haemophilus aphrophilus and is a rare cause of disease in humans. A recent reclassification of these organisms has placed them in the new genus of Aggregatibacter species. The organism seems to be a normal component of oral flora and has been reported to cause endocarditis, sinusitis, pneumonia, empyema, soft tissue abscess, meningitis, vertebral discitis, and septic arthritis. Brain abscess due to Aggregatibacter is rare. We report a case of cerebral abscess due to Aggregatibacter aphrophilus and discuss the characteristics of this organism.

RESUMO

The authors report a case of orbital cellulitis with abscess formation that developed after surgical management of canaliculitis. The patient developed pain, erythema, proptosis, and limited eye movements 3 days after canalicular debridement. She required urgent drainage of an orbital abscess and was treated with intravenous antibiotics for 2 weeks. Complications from surgical management of canaliculitis are unusual. Clinicians should be aware of the rare but serious risk of spread of the infection to the orbit.

RESUMO

Haemophilus paraphrophilus is a normal inhabitant of the naso- and oropharynx and has been rarely reported as a cause of endocarditis. H. paraphrophilus is a slow-growing and fastidious gram-negative bacterium and belongs to the HACEK group. We experienced a case of infective endocarditis due to H. paraphrophilus. The organism was repeatedly isolated from the blood cultures of a 60 year -old patient presenting with high fever, chills, cardiac murmur, and change of mental state. The patient had a history of mitral and tricuspid valve replacements and had been followed up for complications of cirrhosis of liver such as esophageal varix and oral bleeding. The isolate was identified as H. paraphrophilus by the characteristics, including factor V requirement, negative indole, urea and ornithine decarboxylase and acid production from glucose and lactose. Antimicrobial susceptibility testing by the disk diffusion method showed that the organism was susceptible to ampicillin, chloramphenicol, tetracycline, trimethoprim/sulfamethoxazole, cefotaxime, ceftazidime, aztreonam, imipenem, and ciprofloxacin. The patient expired on hospital day 8, probably due to complications of cirrhosis of liver To our knowledge, this is the first case of infective endocarditis caused by H. paraphrophilus in Korea.
